Warnings & Safety Instructions

The unit incorporates components that are directly connected to the power supply network. The rear section of the main board and the covered left section of the power manager board remain energized even after the unit has been turned off. The voltages present in this section of the circuit are the line voltage and the pre-stabilized direct voltage (which amounts to 390 V after the unit has been switched on and drops to the peak value of the mains voltage after the unit has been turned off). This section is specially marked on the main board. Three other voltages can be present as well: the medium-frequency supply voltage for the screen illumination after the unit has been turned on, the power controller’s output voltage of up to 200 VDC as soon as the unit is activated, and the HF output voltage of up to 12 kVpp. Therefore, be sure to disconnect the power cord from the power supply before performing any repairs. This is the only way to de-energize all components inside the unit! For certain servicing tasks, it is necessary to operate the ME402 in an open condition because measurements or settings must be carried out. In such cases, be sure to observe the usual safety guidelines for preventing electric shocks. Since the switching power supply unit incorporates capacitors that may remain energized for some time after the unit has been turned off, an electric shock may be caused if you touch them. This danger is particularly high in the event of internal faults.

Service Functions

4.1

Service Menu

The maxium® offers basic setting and service functions. These are grouped in the “Service” submenu.

MENU

Service menu Pressing the MENU button on the maxium® and selecting the Setup menu item takes you to the Setup submenu. Selecting the last item, Service, takes you to the text editor, which is usually used for entering program names. In this context, the editor is used for restricting access to the Service functions, as some of them can lead to irreversible actions that are possibly unintended by normal users. Therefore, you must first enter 2020 and select the “Enter” button in order to access the Service menu. Selecting “Escape” takes you to the next higher menu level. Pressing the MENU button a little longer returns you directly to the top or main level.

KLS Martin maxium® / maxium® Beamer Service Manual The filling level of the argon gas cylinder is displayed on the screen. The parameter used for deriving the indicated filling level is the gas pressure present at the input of the Beamer. However, this is not a constant value, as the output pressure of the pressure reducer – which is identical with the input pressure of the Beamer – varies with the input pressure of the pressure reducer. Such input pressure, in turn, is identical with the current pressure of the gas cylinder – which also represents the filling level of the cylinder. To make sure that the filling level of the cylinder is indicated correctly, the symbol displayed can be adjusted to reflect actual conditions. Proceed as follows: •

First, open the corner valve on the gas cylinder. The gas pressure reading on the manometer of the pressure reducer must be at least 100 bar for the procedure to be carried out. Subsequently, close the corner valve again.

•

Via the menu path Beamer Parameters / Filling Level Calibration, select the item Measure 100 bar and press the rotary switch. This calls up a numerical display.

•

Use the PURGE button on the MB402 to activate a gas flow, thereby observing the manometer on the pressure reducer. Hold the button down until the indicated residual pressure has dropped to 100 bar with the corner valve closed. Wait until the display has settled to show a stable value, then press the rotary switch to log the value.

•

Select the Measure 30 bar menu item and press the rotary switch.

•

Again, use the PURGE button on the MB402 to activate a gas flow, thereby observing the manometer on the pressure reducer. Hold the button down until the residual pressure indicated has dropped to 30 bar with the corner valve closed. Wait until the display has settled to show a stable value, then press the rotary button to log the value.

•

Select the Ready menu item and press the rotary switch for confirmation.

This terminates the procedure. Reset to Standard (from SW0.311) Service menu

Service menu




Please press ENTER button as soon as measured value is stable




If the gas cylinder pressure has already dropped below 100 bar, a standard setting can be selected instead of calibration via the two pressure levels (as described above). This means using fixed values good enough for sufficiently precise pressure indication. Select Beamer Parameters / Filling Level Calibration from the menu, then select Reset to Standard and press the rotary switch for confirmation.

Pressure alarm threshold : 30 bar


If the filling level drops below the set minimum value, a warning signal is automatically emitted. The minimum value (or alarm threshold) can be adjusted by selecting Beamer Parameters and then the Alarm Threshold item and confirming by pressing the rotary switch. Thereafter, you can adjust the alarm threshold across a range of 30 to 80 bar by turning the rotary switch. The factory presetting is 30 bar – a level that provides sufficient reserve when using a 10-liter gas cylinder. When using smaller gas cylinders, the alarm threshold should be set higher.

From HW02, the maxium® features a clock with calendar function supporting the log functions. Once the unit has been switched off, this clock is powered by a battery located on the controller board. As the clock is not required for operating the unit as intended, a discharged battery does not restrict its usability in any way. The clock is set to Central European daylight saving time (CET) ex factory. There is no automatic changeover from daylight saving time to standard time. The time is also displayed, together with the battery status, via the Device Status / System Information menu path. To set the clock via the path Device Settings / Time, select the Set Time menu item. The parameters “year”, “month”, “day of month”, “hour” and “minute” can then be individually selected and adjusted.

Block all currents with output voltages > 4 kVp


Cancel Yes No

This menu item allows you to limit the maximum output voltage to 4 kV for all currents, e.g. in order to protect endoscopic accessories against overload. However, this setting option makes sense only for units up to (and including) HW02. In higher hardware versions, the newly implemented HF output voltage control function ensures that output voltages exceeding 4 kV are limited to open-surgical spray and argon coagulation currents.

Bar graph: Measured power instead of set power

Basic settings


Cancel Yes No

If used in the factory-preset mode, the horizontal bar graph below the dosage indicator shows the current dosage setting relative to the maximum value available. As the rotary switch has no left or right end stop indicating the minimum and maximum positions of the adjusting range, the bar graph is intended to keep users informed about their currently set output power level relative to the overall adjusting range. The menu item “YES” allows you to switch the bar graph from indication of the set power to indication of the actual HF output power relative to the set power. In this mode, the bar lights up on only when HF power is actually emitted. This function is useful in cases where the user is in doubt about the correct power setting for an application. For automatic cutting processes, the preset power should always be higher than the power actually required for the task at hand, as this provides “reserve” for controlling power peaks. If the indicated actual value constantly reflects the maximum level, then the preset power is possibly too low. Selecting the “No” menu item returns you to the original bar graph mode (setpoint indication).

During HF current activation, the unit is locked against changes in its settings – except for HF output power adjustments, which are possible also during activation (when using the factory presetting). By selecting “Yes”, however, this menu function allows you to lock the unit against output power adjustments during activation as well. The previous function (power adjustment during activation enabled) can be restored at any time by selecting the “No” item, thus releasing the lock.

Sound of activation tones and of channel differentiation


Escape Sound Scheme 1 Sound Scheme 2 Sound Scheme 3 Sound Scheme 4

Previously, the activation tone for cutting was lower-pitched than that for coagulation, while there was no difference in pitch between the monopolar and bipolar operating modes. With the implementation of SW2.360, this system has been changed. Now there are four different sound schemes as follows: Sound scheme 1: This is the new default sound set: Cut = high pitch, Coag = lower pitch, plus pitch difference between monopolar and bipolar, i.e. 4 different acoustic activation signals altogether. Sound scheme 2: Same as scheme 1: Cut = high pitch, Coag = lower pitch, but no pitch difference between monopolar and bipolar, i.e. 2 different acoustic activation signals altogether. Sound scheme 3: Same as scheme 1, but additional differentiation between M1 and M2, B1 and B2, and monopolar and bipolar, i.e. 8 different acoustic activation signals altogether. The difference between Bipol Cut B1 and B2 has been made particularly noticeable in response to user requests. Sound scheme 4: “Martin Classic”: Coag = high pitch, Cut = lower pitch. This setting corresponds to the previous maxium® sounds used up to software version V1.357, reflecting the delivery status of all units with hardware versions up to HW03 inclusive. This means that KLS Martin customers can set their familiar sounds. Sound scheme 1 is automatically activated during software updates (default setting). Users who wish to work with their familiar sound configuration therefore must switch over to sound scheme 4 in a one-time action.

This menu item allows you to check the release status of the software of all the programmable systems of the unit. Apart from the main controller, programmable systems are the two CPLDs (complex programmable logic devices) for the sound generator and the HF current pulse pattern generator located on the controller board, the controller on the patient circuit side of the monopolar board, and the Argon Beamer. These programmable peripheral systems can also be supplied with program updates by the main controller. However, the patient-circuit and Argon Beamer controllers require a bootloader for this purpose (a bootloader is a program part that maintains communication with the main controller independent of the main program while the old main program is being erased and the new main program installed). Whether the bootloader is installed or not is indicated here as well. The updating process is carried out automatically where possible. If not possible because there is no bootloader installed, both the current version and the new version (the one that could be installed with a bootloader) are displayed. The controllers can only be programmed with a bootloader from outside, using the programming interface provided on the respective board. A CAN bus adapter for smoke evacuator control is recognized as well and indicated here if connected.

Starting with hardware version HW02, all electronic components are equipped with identifiers, i.e. small, non-volatile memories in which the module’s ID number, serial number and version number are stored. All of this information can be displayed in this menu. From HW04, SW2.360, the unit automatically recognizes and displays the socket version as well. The identifier data is used to determine and display the hardware version of the unit. In this process, non-permitted module combinations are detected as well – in which case an error message is displayed and the unit blocked as a result. The size of the main-board program memory is displayed in addition. Up to HW01, the respective storage space was only 1 MB; from HW02, 2 MB are now available. This larger memory size is required for software updates for V2.368 or higher versions.

Service Setup With some HW00 and HW01 versions, there may be problems with nominal power setting for high-voltage coagulation currents, notably spray coagulation. In such cases, the menu now (SW0.251 or higher) allows switching over to another setpoint table to achieve the desired output power. There are two alternatives available in addition to the standard table (index 0). The high spray output power “spread” is due to an insufficiently dimensioned HF generator control circuit. However, this problem was already detected and cleared during HW01 production and therefore is no longer relevant to subsequent hardware releases. For maxium® versions HW02 or higher, access to this function therefore has been blocked.

4.1.6

Service menu Device settings


Service menu Device settings



Service Setup To update the operating program of the main controller, it is normally enough to connect the ME402 to the RS232 interface of a PC and then start the marFlash tool. With HW00 and HW01 units, as well as in cases where it is not possible, for whatever reason, to start the updating process directly (USB RS232 adapters tend to cause problems, for example), the unit must be set to boot mode manually by selecting the corresponding menu function. This clears the screen, causing it to turn violet or dark. If no data transfer takes place, the unit will remain in this state, but restarting it is enough to make it ready for operation again. For more detailed information on the topic of updating, please see the following section.

V 5.0

31


4.2

Updating the Operating Program

On the maxium®, updating the operating program (software update) requires no program memory exchange. Rather, this can be done externally by simply overwriting the memory contents by data transfer from a PC. As from software status 1.336, even the memory contents of the patient circuit controller and the maxium® Beamer controller can be updated in this way in addition to those of the main controller. However, this presupposes a bootloader in these controllers (see section 4.1.4). For a detailed description of the updating process, please refer to the CD which, among other material, contains the new operating software and can be obtained from the Martin Service Center.

4.2.1

Aids Required for the Update

To update the internal maxium® software, the following equipment is required: •

A serial RS232 modem cable (1:1) with male DSUB9 connector at one end and a female one at the other end. Do not confuse this with a null modem cable used for connecting two PCs. Such cables have female connectors at both ends and cannot be used even with an adapter (gender changer)!

•

This cable must be connected to the female 9-pin DSUB9 socket designated “RS232” on the maxium®, and to the PC’s socket that is either designated “Serial”, “RS232” or labeled “I0I0I“ (usually a male DSUB9 socket or, in the case of laptops, frequently a PS/2 socket (such as the mouse connector)). In the latter case, you also need a PS/2-DSUB9 adapter. For portable PCs that no longer feature an RS232 serial interface, a USB-RS232 adapter must be used.

•

A laptop/PC with Microsoft Windows operating system and a free serial interface that can be used by the operating system, e.g. COM1.

•

Program marFlash, which is also available from the CD containing the current software. For installation and troubleshooting, please refer to section 4.2.4. The previously used “Flashit” tool should not be used anymore since it does not support the program memory extension to 2 MB. As a result, software version 2.368 or higher versions can no longer be programmed with that tool.

•

The current operating program for the ME402 maxium® in the form of a me402_VX.XXX.h86 file, with “X.XXX” standing for the current version. This program is available on a CD together with the installation program.

If a maxium® Beamer is available, you should connect it, although this is not mandatory because from version 1.335, the maxium® can automatically update the Beamer later.

4.2.2

Normal Software Updating Procedure

Once the PC and the maxium® have been connected with each other via the specified serial cable, and after the current download program has been installed from the CD if necessary, proceed as follows: 1. Turn on the PC and the ME402.

32

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 2. Call up the marFlash program and load the file with the new software via the “File” dropdown menu item. 3. On HW00 or HW01 versions of the ME402, select the Setup menu item and then the Service item as described in section 4.1.6. This activates the text editor. Enter the access code “2020” and confirm with Enter. Now select the item Program update in the Service menu and confirm by pressing the rotary switch. The screen will now turn completely blue and then dark – a normal process. The ME402 is now in boot mode and awaits commands and data via the serial interface. This step is obsolete with units from HW02, since the boot mode will be activated directly from the PC via the serial interface in this case. 4. Click Upload in the marFlash dialog box to start the updating process. After deleting the old program memory contents, the new data will be transferred and burnt in. The whole process will take approximately four minutes for the ME402. Upon completion of the reprogramming process, the ME402 should be automatically restarted. If this is not the case, switch the unit off and on again. The program version indicated on the starting screen should now be the new one. Thereafter, perform the periodic safety checks as specified in section 11. For units with hardware status HW00 and – partly – HW01, the basic setting (calibration) for the monopolar high-voltage coagulation currents must be checked in addition, following the instructions given in section 4.1.5. 4.2.3

Extended Software Updating Procedure

If the normal updating procedure is interrupted (due to an interruption of the data transmission process or some other malfunction that causes a data transmission breakdown), turn off the ME402 maxium® and restart it again. If the unit can be switched on again in the normal way, with the old software version indicated on the starting screen, you can simply repeat the normal updating process described in section 4.2.2. However, if the screen remains dark, the reprogramming had already been started but could not be completed, with the consequence that the program memory contains only a non-executable fragment of the new software. In this case, it is no longer possible to prepare the unit for the updating process via the operator interface. Instead, proceed as follows: 1. Open the unit as described in section 6.1. 2. Using a pointed object, shift one of the two slide switches of the boot mode switch to the ON position. If necessary, disconnect the X4 connector (which connects the front board to the controller) from the controller board to facilitate access to the boot mode switch. The two slide switches have the same function; their contacts are connected in parallel. Then reconnect the cable to X4. 3. Reconnect the serial connecting cable to the PC, then start the marFlash program. 4. Reconnect the mains cable to the PC. CAUTION!

7. The unit will not be restarted automatically. Once marFlash indicates that the data transfer has been successfully completed, switch off the ME402 and disconnect the power cord as well as the connecting cable to the PC from the unit. 8. Reset both slide switches of the boot mode switch to their OFF position. If necessary, again disconnect the front board’s connecting cable to X4 and reconnect it afterwards. 9. Perform functional check. Reconnect the power cord to the unit and turn it on. The self-test screen must now indicate the new software version. 10. Disconnect the power cord again, then close the unit as described in section 6.1. 11. Thereafter, perform the periodic safety checks specified in section 11. For units with hardware status HW00 and – partly – HW01, the basic setting (calibration) for the monopolar high-voltage coagulation currents must be checked in addition, following the instructions given in section 4.1.5.

The marFlash Program

In principle, the marFlash program does not require installation – marFlash can be started also from the CD/DVD directly. Nonetheless, it certainly makes sense to test the software first because access to the serial port can cause problems. Once the system has been configured successfully, experience shows that it runs very smoothly. The “marFlash” program can only be used for updating Martin units of type ME402 maxium® with the associated maxium® Beamer. Neither a dongle nor licenses are required for this. When starting the program, the following problems can occur: •

Despite the fact that a serial port is available on the PC, this port may not be available because it is used/blocked by another software. The culprit may also be the maxiumPC program described in section 4.3! In all other cases, try to find out which software is currently using the port, then cause it to unblock it. A typical representative of such programs is the Nokia Communicator, which is a self-triggering program and blocks the serial port permanently. It is easy to deactivate such programs via the task bar. This reliably unblocks the port.

•

Whether a RS232 serial port is really available or not can best be checked with the terminal program Hyperterm, a Microsoft Windows accessory. The baud rate should be left at 57,600 BAUD.

•

Find out the correct serial port (COM port). This requires some testing on a trial-and-error basis. Note that this involves some traps. Other programs that use the serial interface can block marFlash – e.g. the mouse driver or unintentionally opened programs (e.g. mobile address management via Outlook, or the Nokia Communicator software), internal modems or IrDAs (changeover switch often hidden in the PC’s setup). Normally, however, it should be possible to run the program with any serial port that can be opened with Hyperterm, the Microsoft Windows terminal program. Note: Be sure to terminate Hyperterm prior to starting marFlash! If not terminated, Hyperterm itself could block the serial port!

Advanced portable PCs no longer have an obligatory RS232 interface. Rather, they use adapters that can be operated at the USB port and provide a RS232 cable connector. However, experience shows that these adapters do not always work properly. Especially in light of the great number of possible combinations between PC models and adapter models, it is hard to give reliable advice regarding the best choice. In case of problems with a USB adapter, the following “tricks” might help: •

Terminate all other programs: Messenger, Firewall and any other tool that sporadically draws on the computer’s resources (e.g. disconnect from network).

•

Use a different make of RS232/USB adapter.

•

Reset the protocol of the serial interface used (but only this one!!) from “None” to “Hardware flow control”. (This is not really logical, but it may help!)

In a nutshell: Just find out whether the adapter really “holds out” to the end of the programming process in a given configuration without any communication error or breakdown. Otherwise, only the use of a PC with RS232 interface will help.

Updating the Subsystems of the ME402 and MB402

The ME402 maxium® with MB402 maxium® Beamer features several programmable subsystems. While previous software updates lacked the software required for these subsystems, software versions 1.336 or higher are capable of updating some of these subsystems as well if necessary. This applies to the monopolar patient circuit controller, the CPLDs on the controller board and the maxium® Beamer. The version check is carried out during the initial self-test. The subsystem updating process takes place only once (if required), namely immediately after the first restart of the system following updating of the main controller’s operating program (as described above). Of course, such subsystem updates require some additional time during the first restart. It also presupposes that the software of these subsystems already includes a bootloader. The presence of a bootloader can be checked via the Service menu as described in section 4.1.4. HW00 and HW01 units do not have a bootloader as a serial feature; programming of a bootloader is possible only directly via the programming interface of the module or the main board of the Beamer, respectively. This also requires special programming adapters and tools. If installation of bootload capability on such a system is required, please contact the Martin Service Center.

4.3

Readout and Transfer of the Unit’s Settings

From SW2.368, the settings of a unit can be transferred to another ME402 unit or be stored on a PC or loaded/restored from a PC. This is done via the serial RS232 interface that is also used for software updates. The minimum software status required for transferring settings from or to a ME402 is V2.368. The software status is displayed during power-on or may be checked as described in section 4.1.4. If a software version lower than V2.368 is used, then a software update has to be performed in the first place. However, this requires an extended program memory of 2 MB, which is a serial feature only in units with HW02 or higher hardware versions.

4.3.1

Transfer from one ME402 Unit to Another (Back2Back)

If a unit’s settings are to be copied to another unit, then the serial RS232 interfaces of the two units have to be connected with each other. To do this, please use the serial connection cable (which is also used for software updates) in combination with a null modem adapter that changes the gender of the cable plug from female to male. Do not connect the female end of the cable without adapter to the adjacent CAN socket! A standard null modem cable as commonly used for connecting two PCs cannot be used here since it features female connectors at both ends.

36

V 5.0


As soon as both units are connected to each other, a menu appears on both screens which is not accessible via the other menu levels. Selecting the appropriate menu item enables you to decide whether to transfer or receive only the stored programs, only the settings (preferences) associated to the stored programs, or both together. To transfer the unit’s complete setup to another unit, choose the item “Send both” for uploading or “Receive both” for downloading. Note that the function of your choice needs to be selected only on one of the two units. Subsequently pressing the rotary switch for confirmation automatically sets the other unit to the complementary operating mode, no separate setting required.

Transfer starts upon pressing the rotary switch, type and status are displayed.

V 5.0

37

KLS Martin maxium® / maxium® Beamer Service Manual At the end, a message is displayed informing the user about success or failure of the data transfer. If the transfer failed, the procedure has to be repeated, else the receiving unit cannot be operated.

To exit the transfer operating mode, the two units must be separated again by disconnecting the serial cable and pressing the rotary switch.

4.3.2

The maxiumPC Program

maxiumPC is a simulation of the ME402 on a PC. Along with other tools, the simulation program is available on the software update CD, together with a detailed description.

maxiumPC simulates the ME402 with the same software version with which it is stored on the CD. Consequently, maxiumPC always has the same version status as the simulated software. The hardware to be simulated can be selected, which enables simulation of older hardware versions as well. Among other options, maxiumPC can be used for the following: •

Learning and demonstration of the functions and the handling/operation of the ME402 without any need for a physical unit.

•

Generation of graphics of the screen contents (screenshots) for use in user manuals, service manuals and sales/marketing literature.

•

Generation of user-specific settings on a PC, which can then be uploaded to the maxium®.

Reading out user-specific settings for filing them or transferring them to other maxium® units.

The program can be run on any PC with Microsoft Windows operating system and can be started from the CD directly. No special installation is required. 4.3.3

Transfer from a maxium® Unit to a PC or Vice Versa (Back2Laptop)

The transfer of settings from a ME402 to a PC or vice versa is done in the same way as described in section 4.3.1 for two maxium® units, with one of the units simulated on a PC using the maxiumPC program. In a first step, using the serial connection cable without null modem adapter, connect the ME402 to the PC in the same way as for software updates, then start the maxiumPC program. The data transfer menu must now be displayed on both the ME402 and the simulated unit. You can now set the transfer mode either on the ME402 or on the simulated unit. The simulated unit can be loaded with a stored setup from the PC in order to transfer it to the ME402. Conversely, a setup can be transferred from the ME402 to the PC and can be stored there. MaxiumPC generates setup files with the “X” icon of the maxium® logo and the extension .EPM. The files for setting the hardware configuration have the extension .HWC and are also marked with the “X” icon. The programs maxiumPC and marFlash should not be opened simultaneously on the PC since both of them use the serial interface independently and therefore may impede each other in accessing the serial interface.

Hardware and Software Statuses, Spare Parts Lists

5.1

General Procedure

Most technical products offered on the market are subject to a continuous process of improvement that leads to technical changes at more or less regular intervals. This poses a problem for the service technician insofar as he must be able to deal with several versions of the same type of unit. Before starting any repair or servicing work, therefore, it is mandatory to determine the version status of the unit at hand! In the case of KLS Martin ME units, you can easily check this via the serial number, which has the following structure: ME402 m XX XX XXXXXX

Type of unit Type of socket module Hardware status Software status (not identical w. version number!) Consecutive production number In addition, ME402 units indicate the current software version number (a consecutive number) on the screen during the initial self-test (carried out after turning on the unit). V 5.0

5.2

Hardware Status

The hardware status is determined by: •

Revision status of the boards

•

Revision status of the mechanical construction

•

Adjustment revision status

The boards feature one or two labels with the module ID number (“C40” number or 6-digit item number), a 6-digit serial number and a version number. As from hardware (HW) status 02, some ME402 boards are additionally equipped with an electronic identifier, i.e. a small memory that also stores this data and can be accessed by the main controller. From HW02, the hardware status of any such board therefore can be easily checked via the “Service” menu. If the hardware of a board is changed in the way of a technical improvement that does not affect the interfaces or the intended use of any of the features of the unit, then the version number is simply incremented and the HW status remains the same. Only if the new version is no longer connection-compatible to the previous hardware, or if it provides modified or new features, the module is assigned a new item number and the hardware status is incremented in addition. If a board is repaired by the manufacturer, it is marked with an additional repair label. Where possible, such boards are upgraded to current revision status and are then used as replacement boards (“exchange boards”) for repairs following comprehensive testing. The following paragraphs are intended to give you an overview of the various configurations, with details on the differences as well as the compatibilities between the various revision statuses. If revised boards are released, this is always accompanied by a description of the new configuration. The corresponding documentation is distributed by the Martin Service Center through the same channels as this service manual.

ME402 Hardware Configurations and their Components

5.3.1

Hardware Configurations HW00 and HW01

The hardware version 00 (HW00) is the first serial hardware configuration. HW01 was mainly motivated by the launch of the maxium® Beamer MB402. To this end, the maxium® ME402 had to be fitted with a Beamer connector. In addition, the connector for the screen connecting cable was transferred to the rear side of the controller board. Apart from general optimizations, the following functions have been newly integrated: maxium® Beamer operation (from SW00.296), new monopolar coagulation currents with lower output voltages (from SW00.311), improved regime for the SealSafe currents (from SW00.263), new argon coagulation currents with time regime (Pulsed Argon, from SW00.325), and an optional “baby” neutral electrode (from SW00.331). With SW00.331 and higher software versions, the output voltage can be limited to 4 kV by way of a special Service menu function; besides, the Standard program and the factory-preset (suggested) programs have been revised, with inclusion of a new Service menu function that allows modification of the Standard program.

HW00 serial numbers:

ME402x0000 040100 to ME402x0000 040149


ME402x0100 040149 to ME402x0100 040599

First software version in HW00:

00.247

First software version in HW01:

0.263 (does not support the maxium® Beamer yet!) 0.296 (supports maxium® Beamer)

Upgrade options: Use of the new bipolar board II (C40-2155) with improved impedance monitoring and bipolar expander support. This requires version 5 or higher for both the main board and the controller board (so a board upgrade will be necessary if this requirement is not met). The bipolar board II is supported from SW01.333 onwards.

This can be done in two ways: the unit can be subjected to a hardware upgrade by the manufacturer, or the controller board I can be replaced with a new board having an expanded memory. In this latter case, however, all user-specific settings will be lost. The controller board I has no battery backup and therefore no clock. Consequently, it is not possible to use service functions requiring time management. This cannot be upgraded either.

The socket illumination board is powered by the activation indicator board via a plug-and-socket connection. Owing to the design of this connection, both boards must be dismounted if one of them needs to be replaced. As this process involves disassembly of the entire socket module, the plug-in connection has been modified. Both of these boards are no longer available as spare parts.

The following items should be used as spare parts instead: Activation indicator board II: 08-027-00-18, spare part no. 77 (C40-2173-11) and Socket illumination board II: 08-003-00-51, spare part no. 80 (C40-2173-14) Please note that these two boards are not conX10 nection-compatible with the previous models!

Hardware Configuration 02

The main board C40-1925 has been replaced by the new version C40-2165 which, however, is not backward-compatible with HW00 and HW01, and the power manager board C40-1927 has been replaced by the new version C40-2169 (also not backward-compatible with HW00 and HW01). Apart from a newly added electronic “version recognition” function, these two modules do not provide any new functions. The connector plugs of choke L6 have been modified. This also necessitated a new version II of the monopolar board (C40-2224), which differs from version I only with regard to plug connector X4, and a new version II of the monopolar socket module, also fitted with a new connector. The bipolar board I (C40-1930) has been replaced with the bipolar board II (C40-2155). Board II has a new impedance monitor offering a higher resolution for higher tissue resistances – a change necessitated by the introduction of the Auto Start/Stop functions. Moreover, the bipolar board II supports the use of the bipolar port expander, which allows connecting two instruments (for bipolar cutting and bipolar coagulation) to the bipolar output B2 in the Martin (“m”) version. This is controlled via the instrument recognition function that is available from SW1.336. To ensure that the old hardware configuration can be distinguished from the new one, an electronic module recognition function has been integrated for the major boards. This function also allows displaying the hardware versions and serial numbers of the various modules for servicing purposes.

Hardware Configuration HW03

This hardware configuration does not represent a production status of its own. Rather, some HW02 devices have been rebuilt for limitation of the monopolar output voltage – a feature that is a regular part of serial production only in units with hardware status 04 or higher. The HW03 configuration was built only in the KLS Martin (“m”) version. Nonetheless, it is possible to retrofit the front part with connections for other accessories. As the HW03 front is identical with that of HW02, the HW02 spare part numbers are to be used when changing over to a different socket module. Lowest software version required: 1.343

Hardware Configurations HW04 and HW05

Compared with HW02, this configuration newly offers the additional option of limiting the monopolar HF output voltage to defined levels. Besides, the properties of some monopolar currents have been optimized by a general improvement of the HF output current regulators. Moreover, relative to HW02, a new main board III (C40-2346), a new power manager board III (C40-2337) and a new monopolar board III (C40-2281) have been used in this configuration. These three boards had already been introduced with HW03. Due to the manufacturer’s discontinuation of an electronic component, the controller board has been redesigned (version III, C40-2327). This included a modification of the screen connecting cable and its connector. Besides, the converter for the fluorescent lamps of the screen module has been transferred from the controller board to the front board. And taking future extensions into consideration, SPI bus addressing has also been changed to allow connection of additional users. All LEDs located on the boards of the front part have been replaced with SMD versions. This also necessitated changes regarding the optical guides of the front part. The board with the NE status indicators has been additionally equipped with a hardware identifier to enable the operating program to identify the socket configuration. The front board IIIa (C40-2424) now features the converter for the fluorescent lamps, which was previously located on the controller board. As a new screen module with a different connector for the fluorescent tubes was needed, the front board had to be adapted as well (version IIIb, C40-2471). These changes resulted in the HW05 system configuration. HW04 serial numbers:

Hardware Configuration HW06

Compared with previous versions, this hardware configuration has a completely redesigned bipolar part. This change was mainly motivated by user requests for special bipolar TUR currents and for improved bipolar ligation currents allowing the use of advanced endoscopic ligation instruments. The most prominent feature are the new bipolar connecting sockets. The round combination socket at output B2 of the “m” (KLS Martin) version has been eliminated; instead, both bipolar outputs (B1 and B2) now have the same new combination socket that allows connecting conventional forceps cables with an 8mm coaxial plug as well as instruments with a 4mm plug (either with or without additional control contacts for finger switch operation and instrument recognition). In the international (“i”) version, the 8mm coaxial socket has been eliminated; in the Erbe (“e”) version, the 8mm socket has been replaced with a 12mm socket. This means, of course, that the previous bipolar port expanders can no longer be used, which is why a new port expander has been developed for HW06 units and higher hardware versions. The bipolar board II (C40-2155) has been replaced with a “bipolar module III” consisting of two boards: C40-2532 and C40-2533. Even though the module connects two separate boards with each other, only the complete bipolar module III is available as a spare part because preadjustment of the module would otherwise not be possible. The scope of functions has been expanded to a point that it is now possible to measure and regulate the HF output voltage, the HF output current, as well as the direct voltage that is superimposed on the HF output voltage during the cutting process. A dedicated microcontroller supports the new as well as the old functions. The previous standby circuit for the mains voltage has been replaced with a relay that works like a mains switch. This in turn necessitated replacing the power manager board III (C402337) with power manager board IV (C40-2510) to ensure support for the changed function. Due to the modified bipolar part and the modified standby circuit, the main board has been replaced with a new version IV (C40-2509). This change also involved a replacement of the main-board optocouplers (used for communication with the monopolar patient circuit controller) with versions that offer a higher transmission frequency. This in turn made it necessary to adapt the interface on the monopolar board, so this module had to be replaced by a new monopolar board IV (C40-2511). However, the functions of this board have not been changed.

The controller board newly introduced with HW04 continues to be used. The controller board has no adjusting positions. With the launch of HW06, bipolar TUR currents are optionally available against an extra charge. This option therefore requires special release.

To this end, the serial number of the unit is stored on the controller board. If bipolar TUR currents have already been released for use, orders for a controller board III as a spare part for HW06 should always include the serial number of the unit, together with a notice requesting the bipolar TUR option to be enabled again.

Software Status and Software Version Numbers

5.4.1

General Information

The “ME402 maxium® & MB402 maxium® Beamer” system incorporates altogether four independent program memory systems: •

Program memory of the main controller

•

Non-volatile memories in the CPLDs for HF current acoustic signals and pulse patterns

•

Program memory of the monopolar patient circuit controller

•

Program memory of the maxium® Beamer controller

The main controller program can be updated from outside via the serial RS232 interface. The main controller in turn is capable of updating the programs stored in other modules of the system as necessary, and provided those modules have the required boot-load functionality. However, such functionality is available only from software version 08 in the case of the patient circuit module, and from software version 2.07 in the case of the Beamer. This can lead to a situation in which the ME402 can no longer be operated after updating the software of HW00 or HW01 units because it may not be possible for the new software to update the patient circuit controller. The same applies to the Argon Beamer. Therefore, prior to updating the software of hardware versions 00 or 01, please check whether the intended update also affects the patient circuit controller and the Beamer or not! In case of doubt, contact the Martin Service Center. Status and version number of the main controller software are briefly displayed in the format “SS.VVV” after turning on the unit. Whereas the three digits after the dot (“VVV”) represent a consecutive version number reflecting the development status, the two digits preceding the dot (“SS”) indicate the software status (as displayed in the serial number as well). If the software status number indicated in the serial number (digits preceding the dot in the number displayed on the screen) changes, additional hardware upgrades or external software updates for specific peripheral modules loaded with programs may be necessary as well to ensure that the new software version is executable and all new features are available for use. Please check in such case! 94

V 5.0

5.4.5


First software installed in HW01 serial units. Even though HW01 meets all the requirements for operating and controlling the maxium® Beamer, this version still does not support the maxium® Beamer! Installation ex factory in units with serial end numbers 040150 to 040220. Improvements against 0.257: 1. Improved automatic bipolar coagulation function. 2. Improved SealSafe function.

5.4.6


Update for 0.263 in units up to HW01. Installation ex factory in some units with serial end numbers 040150 to 040225.

V 5.0

95

KLS Martin maxium® / maxium® Beamer Service Manual Improvements and new functions against 0.263: 1. Complete integration of the maxium® Beamer into the user interface of the ME402. 2. Improved CAN communication with the Argon Beamer MB 181. 3. Active leakage current limitation for monopolar cutting currents as well. The following faults have been removed: •

Failure of the bipolar auto-start function if both bipolar channels (B1 and B2) are activated simultaneously in a specific way.

•

Display of the NE field with a wrong background color if a previously selected argon current is deselected and the channel subsequently activated.

5.4.7


Update for 0.263 and 0.296 in units up to HW01. Installation ex factory in units with serial end numbers 040226 to 040234. Improvements and new functions against 0.296: 1. Acoustic acknowledgement signal indicating SealSafe termination. 2. When selecting a bipolar current at B1, a footswitch pedal is automatically offered if not assigned already. 3. Improved active leakage current limitation. 4. Simplified procedure for adjusting high-voltage coagulation currents to setpoint power; procedure extended to include all high-voltage coagulation currents. 5. Plain-text messages updated for other languages. 6. Improved internal temperature monitoring.

5.4.8


Update for 0.263, 0.296 and 0.305 in units up to HW01. Installation ex factory in some units with serial end numbers 040150 to 040235. New functions, compared with 0.305: 1. Teach-in function for calibrating the argon filling level indicator. 2. Czech included as a new language regarding plain-text messages. 3. Improved monopolar Auto Stop function.

96

V 5.0



New release for HW01 units, plus update. Installation ex factory in units with serial end numbers 040236 to 040339. Improvements and new functions against 0.311: 1. Two new monopolar contact coagulation currents – Clamp Coag and Forced Clamp – with a lower output voltage to reduce the glove puncture risk when using clamps for coagulation. 2. Two new endoscopic argon coagulation currents with pulse/pause time regime. 3. Improved view angle switching function for the display screen. 4. Acoustic acknowledgement signal for SealSafe termination improved. 5. Special activation tone for simultaneous HF current activation in Duo Spray mode. 6. Improved text editor for entering program names.

5.4.10


New release for HW01 units, plus update. Installation ex factory in units with serial end numbers 050340 to 050447. Improvements and new functions against 0.325: 1. Version 0.331 is the first version that can be programmed with the new marFlash flashloader. marFlash cannot be used for older versions! 2. The Standard program has been modified slightly: instead of Contact Coag, the new Clamp Coag current with lower output voltage is now offered. 3. The Standard program can now be adapted to user needs (via Service menu, to be performed by service technician). 4. It is now possible to select – via the Service menu – whether the maxium® is to start up with the last-used program (in its unmodified form) or with the Standard program. 5. To enable adaptation of the maximum output voltage to third-party accessories with a specified dielectric strength of only 4 kVp, the Service menu now provides the option of locking all types of current with an output higher than 4 kVp. In effect, this leaves only Endo Spray as a spray current, since the Spray, Argon Beam, Forced Uro Coag, Duo Spray and Macro Spray currents all exceed the limit of 4 kV and are automatically locked when using this setup option.

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 6. The following factory-preset programs have been newly included: Gyn. Portio Gyn. Hysterectomy Lap. Hernia Lap. Hernia with EndoSeal Uro Open with SealSafe Visceral Surg. with SealSafe Gen. Surg. with Beamer Mamma with Axilla Pediatrics 7. The following programs have been removed from the list of factory-preset programs: Visceral Surgery Uro Rollerball Mucosal Resection Papillotomy (needle) Lap. Cholecystectomy I Canady Applicators Polypectomy (pedicled) 8. All programs equipped with the new, “glove-compatible” coagulation currents (with reduced output voltage) where applicable. 9. The current type attributes – such as coagulation degrees or auto-start delays – are now handled correctly including all transitions: retain, accept, reject, etc. 10. The footswitch pedal field now features a clock for the “auto-start delay” attribute. 11. Baby NE completely implemented – see “Pediatrics” program. The attribute is saved. Currents that should not be used for pediatric purposes are completely locked. The remaining currents are limited to power settings that can be safely used with baby NEs. As it is the current increase and not the output power increase that takes a neutral electrode to its limits, it is not possible to specify a maximum power setting for all currents; rather, the maximum setting depends on the selected current but never exceeds 100 W. If the given maximum is reached, or if the user attempts to select a locked current, a corresponding text message is displayed. Bipolar currents are not affected by this setting. 12. The foreign-language texts have been revised and supplemented. 13. Text editor improved in terms of color and shadow silhouettes; plus return to small, more pleasing characters. 14. Automatic offering of a pedal: function extended for pedal-typical currents. 15. Additional plain-text error messages included for maxium® Beamer. 16. Program preview build-up process on screen accelerated.

98

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 17. The bipolar impedance monitor now triggers the message “Tissue contact” if auto-stop occurred or if the electrode is already in touch with the tissue at the time when an auto-start current is selected. 18. When grasping tissue while using the auto-start delay function, the red frame now jumps to the new channel immediately – and not only after the delay time has elapsed, as previously the case. 19. During auto-start delay, a corresponding message is displayed on the screen: “Bipolar auto-start delay in progress…”. 20. The channel texts for SealSafe are now displayed as “Bipo Sealing” instead of “Bipo Coag”. This is intended to make clear that the process involved is not just plain coagulation. 21. The Duo Spray activation alert has been changed: triple tone (triad) retained, but pitch set a little higher. 22. The indicators (LEDs) on the front panel are now successively switched on group-wise during the initial self-test. This is intended to facilitate recognition of a missing color. The following functions have been debugged: •

Representation and handling of argon currents in all Argon Beamer constellations.

•

First release for HW02 units, plus update. Installation ex factory in units with serial end numbers 050496 to 061010. Changes and new functions against 0.331b: 1. Integration of automatic internal module recognition via one-wire bus. 2. Support for bipolar board II. This is a new HW02 board with improved (more sensitive) automatic function when using forceps, thus minimizing patient auxiliary currents. This new board is connection-compatible, but requires at least software 0.336, due to differences in internal control. V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 3. Optional “bootload” software updating for monopolar patient circuit controller and Argon Beamer. This presupposes, however, that the patient circuit controller and the Beamer are already run with a software that incorporates a bootloader. 4. Bipolar instrument recognition for the new bipolar expander implemented. Different instrument codes are now recognized at the multifunctional bipolar socket B2, thanks to its additional control contacts. Provided the expander is recognized, the Cut current and the Coag current are conducted to two separate outputs of the expander. This enables two different instruments to be connected to the multifunctional socket B2. 5. Support of an adapter for activating a connected smoke evacuator via the CAN interface. 6. The Argon Beamer MB181 is no longer supported.

5.4.13


First release for HW03 units, plus update. Installation ex factory in units with serial end numbers 061011 to 061085. Improvements and new functions against 1.336: 1. Self-test as well as continuous self-monitoring expanded. As a result, the potential error messages have become both more detailed and more numerous. 2. Preparation of parallel tables for the monopolar currents Pure Cut, Uro Pure Cut and Argon Cut, for which the maximum output power is now limited to 350 W. However, these tables are not effective yet in HW02 units. 3. Preparation of changeover to a different current logo and a different name – “Air Beam” – for the Macro Spray current. However, this measure is not effective yet in HW02 units. 4. The Macro Spray (AIR Beam) current has been transferred from the first to the second page of the current selection list, thereby exchanging places with the plain Spray current. This is due to the fact that the plain Spray current is preferred by many users. 5. The Polyp Cut I current symbol has also been provided with a graphical coagulation seam in order to prevent the potential impression that it offered no coagulation at all or less coagulation capability than the current used for large polyps. 6. As the option to adjust the output power during HF current activation is not appreciated by all users, this feature can now be disabled for good via the Service menu. As a result, power adjustment is possible only as long as no activation takes place. 7. The maximum output voltage for Micro Coag has been slightly reduced to prevent spark formation. 8. All error messages and alerts are now displayed in red to ensure easy capture by users. 9. The acoustic error signal regime has been harmonized: two deep tones are now emitted in succession.

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 10. Serious errors are now no longer reversible. Instead, current activation is automatically blocked and the unit must be turned off and restarted before activation is possible again. Repeated activation attempts are rejected and the error message 164 displayed for information. Besides, the error code of the serious event that triggered the locking action is displayed again in such case. 11. The papilla and polyp currents previously tended to be too unstable in their pulse emission performance. Therefore, these and all other currents characterized by a periodic change in their power output have been revised to provide them with a fixed time regime that prevents unwelcome output variations, thus preventing loop electrode damage even in extreme cases. The effectiveness of the DC regulator has also been improved and the voltages have been slightly reduced. To prevent output power fluctuations caused by rapid reoperation of the footswitch, the regime has been changed so that the output sequence now starts with a coagulation phase and ends with the cutting pulse. 12. Introduction of bipolar auto-start currents. These differ from existing Auto Start/Stop currents in that a fixed switch-off threshold subject to a very high resistance has been implemented. This ensures that automatic switch-off takes place only upon releasing the tissue. However, these Auto Start currents are available only if the hardware ID recognition function correctly identified the bipolar board II in HW02 units, as only this board features the higher-Ohmic impedance monitor required for this function. 13. Voltage limitation (from HW03) supported: The monopolar board III (C40-2281) required for this function is automatically recognized. While the power manager board III (C402337) is not a mandatory requirement for running this software, we highly recommend implementing it nonetheless. 14. Various currents have been modified regarding maximum voltage limitation. This change requires a C40-2281 monopolar board (HW03 or higher) to be effective. Besides, the monopolar patient circuit controller must be loaded with version 9.00 at a minimum. 15. Polish has been generally implemented as a 7th interactive language, but still has – like Czech – a limitation in that country-specific special characters cannot be displayed. 16. Portuguese is included as well. All characters are correctly displayed in this case. 17. Fine adjustments implemented for Italian and French. 18. Hardware and software configuration now displayed in the Service menu. 19. Instructed specialized personnel can now put the unit into operation for error/fault analysis purposes even if the initial self-test failed. To this end, “backdoor entry” is now possible by pressing the MENU button (repeatedly if more than one error occurs) and entering the service password into the text editor which is then displayed. 20. This version for the first time has a basic activation log for maximum 36 entries (ring-type memory). Actual output values are not recorded, however, but only represented by fixed values serving as examples. Storage is permanent (non-volatile) in units having a controller board with buffer battery.

101

KLS Martin maxium® / maxium® Beamer Service Manual 21. The new software version V3.02 of the maxium® Beamer is also included for download in this maxium® software version. However, this presupposes a bootloader in the maxium® Beamer. You can check this situation via the Service menu (version indication). The changes implemented relative to V3.01 are limited to the expansion of one tolerance range to ensure that series-specific fabrication spread in some Beamer components is tolerated. Besides, the pressure alarm threshold (e.g. 30 bar) indicated on the maxium® display now fully reflects the true Beamer value. However, it is hardly necessary to update the Beamer specifically with the new software version. Beamer updating is initiated via item “UB” in the Password menu. 22. The ME402 can now display additional activation statistics for the Beamer: Number of (successful) Beamer activations for Cut Number of (successful) Beamer activations for Coag Number of power-on actions This information has previously been stored in the error log – which caused irritation in some cases. We therefore decided to transfer this data from the error log to a separate log. However, deletion of the corresponding entries in the error log should be done only by the manufacturer. 23. The power display of the ME402 has always incorporated a quasi-analog “control bar graph” below the numerical value, indicating the set power relative to the maximum power setting available. It is now possible to choose between this previous indication mode and indication of the actual power output. This setting can be changed permanently and globally via the Service menu. Switching the setting to actual power indication will mean that the bar responds only when power is actually emitted (current activated) at the corresponding channel. 24. The LED self-test has been improved to ensure that LED failure is more easily recognized. 25. Software support for the internal real-time clock to make this clock available for servicing purposes. This presupposes a processor board C40-C2217 version 01 or higher (shipped since February 13, 2006). This clock has no functional relevance at all for the unit. Therefore, if it does not work correctly or has meaningless settings, this does not have any adverse effects. A corresponding Service menu item for setting the clock has been implemented as well, but is offered only if a matching hardware version of the controller board (with functioning buffer battery) is recognized: C40-2217, board version 01 or higher. 26. The buffer battery (3.0 V, Li-cell) – which works only with board versions C40-2217 V01 (delivery started February 13, 2006) or higher – is now monitored. Battery discharge is automatically registered in the Service menu (periodic safety check). The user is not troubled with this in any way. 27. Commonly used bipolar instrument codes are now correctly identified in units with old-type bipolar boards I (C40-1930) as well. An error message is displayed in case of unknown codes. 28. The external Beamer MB181 is no longer supported. Corresponding items have been removed from all the menus. 29. KLS Martin logo and support address, as well as the klsmartin.com e-mail address, have been updated.

5.4.16


First release for HW04 units. Installation ex factory in units with serial end numbers 071231 to 071592. The version V2.360 is the first release version of software SW02, designed for supporting hardware version HW04. When updating previous hardware versions with this software, it is to be noted that such installation will have two consequences: a change in the appearance of the user interface, and a necessity for internal conversion of the codes of user-defined programs. The latter means that it is no longer possible to return to previous software versions (as these cannot handle the new code) – unless a loss of all user-defined programs is accepted. The new software offers the following improvements and new functions, compared with 1.346: 1. This software version for the first time supports units with hardware status HW04, which is characterized by monopolar voltage control (same as in HW03), a new graphics controller, front board illumination control, socket modules (“e”, “i”, “e”) that can be read out, etc. 2. The various different hardware versions are recognized and handled accordingly. V 5.0

103

KLS Martin maxium® / maxium® Beamer Service Manual 3. The top menu level has been modified. There are now 6 last-used programs (LUPs) instead of just 3. The main menu items “Power”, “Current type”, “Pedal” and “Flow” have been removed. This change also necessitated a revision of the Operating Instructions (updated to V4.00). However, this menu change takes effect only for recognized hardware versions HW03 or higher; HW02 and older units will still show the same menu as previously after installing this software version. 4. The initial screen has a new entry: Users Manual V4.xx. This entry is intended as a reference to the valid version of the user manual (“Operating Instructions”) of the maxium®, thus making clear which version of the user manual belongs to the current software version and enabling the user to check whether the user manual at hand is still valid or not. 5. Limitation of the monopolar HF output voltage for HW03 and higher versions. This requires the monopolar board III (C40-2281) as used in HW03 and higher-version units. The following currents are affected by this change (i.e., use monopolar voltage limitation as from HW03): Pure Cut, Blend Cut, Uro Pure Cut, Uro Blend Cut, Polyp I, Polyp II, Papilla I, Papilla II, Care Cut, Soft Cut, Argon Cut; Clamp Coag, Forced Clamp (not in the DUO version), Contact Coag, Forced Coag (not in the DUO version), Uro Coag, Forced Uro Coag, Care Coag, Desiccation. When updating units equipped with older hardware, the new software automatically recognizes and correctly identifies the current hardware configuration. To support the new functions, however, the monopolar patient circuit controller must be loaded with software version 9.0 or higher. 6. The software version 11.02 of the monopolar patient circuit controller with bootloader is included as an update. To automatically update the monopolar patient circuit controller via the main controller, the software version installed in the monopolar patient circuit controller must be V8.0 or higher because the required bootloader is not included in lower versions. Updating systems with hardware statuses lower than HW03 is not necessary, since such older versions simply lack the hardware resources for which the updated software is intended. Where necessary and possible, the update is performed automatically and unavoidably when starting the system for the first time. Upon completion of the updating process, the unit must be switched off and restarted. 7. An Argon Beamer software update (V3.03) is included as well. When connecting a Beamer with older software, it is updated automatically. This process is triggered after switching on the unit for the first time. Upon completion, the system must be turned off and on again. 8. The maximum nominal output power has been reduced from 400 W to 360 W. This change merely affects the monopolar currents Pure Cut, Uro Pure Cut and Argon Cut. Such limitation takes effect automatically and selectively in units with recognized HW03 status. Older hardware versions retain their properties, including the 400W limit.

104

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 9. For HW03 or higher-version units, the Macro Spray current has been renamed “AIR Beam”. This is designed to highlight the superior spray performance of this current compared with competition products, due to the fact that the maxium® generates a higher ionization voltage and, therefore, a surface quality coming close to Argon Beamer standards. The AIR Beam current has also been assigned a new pictogram to set it apart from the conventional spray current. In HW02 or older units, the old pictogram remains in place and the previous name (Macro Spray) is retained as well. 10. Introduction of two new monopolar coagulation currents in Duo mode. In addition to DUO Spray, DUO Prep and DUO Coag are now available as well. These two latter currents are the Duo versions of the coagulation currents Forced Clamp and Forced Coag. All three Duo currents have been set to a default output power of 80 W. As no new hardware resources are required for them, the two new Duo currents are available for units with older hardware versions as well. 11. The properties of the monopolar Super Blend Cut current have been modified by giving it a higher crest factor and higher matching impedance. This makes it particularly well suited for dissecting cuts. In units with hardware versions lower than HW03, the original properties of this current are retained. 12. New current “Soft Cut”. This current is intended for cutting with needle or wire electrodes. It requires the hardware resources of the monopolar board III, which is used from HW03 onwards. Therefore, this current is not offered in units with hardware statuses lower than HW03. 13. The default power for the “Papilla 1” current has been slightly increased to 30 W. This change applies to all hardware versions. 14. The SealSafe and EndoSeal currents have been improved for better sealing results. This change applies to all hardware versions. 15. A new stylistic element has been introduced for current selection, designed to mark currents that are currently not available: the corresponding pictograms are faded down, i.e. displayed in pale blue or pale yellow, respectively. Just as previously, a message is displayed explaining why the current is not available currently. For example, this can be due to activated 4kV limitation or enabled baby NE. 16. The hardware recognition function has been extended to include the monopolar board plus a new function for identifying the type of socket module used. 17. This software version is the first serial version based on the new world language system and therefore capable of representing almost all character sets in use around the world. This enabled us to update the previously “restricted” languages Czech, Danish and Polish. Their special characters are now also displayed correctly. 18. Portuguese (also for Brazil) has been newly added. 19. Danish and Czech have been furnished with an appropriate character set. 20. The editor can now extend over several pages (due to world language system). However, this only concerns languages with double or very comprehensive character sets, such as Russian and Chinese.

105

KLS Martin maxium® / maxium® Beamer Service Manual 21. The program storage function has been converted to a new format already prepared for inclusion of various improvements and additional options foreseeable for the future. This measure was unavoidable because the world language system requires up to three times more memory space for representing program names than the previous system did. Of course, existing programs are not lost when updating existing units. Instead, they are automatically converted to the new format. The user or service representative will notice this by the lengthy startup process (with 65% indicated continuously on the progress bar), but this is a one-time procedure. Switching off the unit during this process is not critical. Only the (hypothetical) step of returning to the original (old) software and the old program format would involve a loss of all converted programs. 22. The names of the various currents have been harmonized across all languages: they are now proper names, so to speak, and as such identical in all languages (using Roman characters). A uniform procedure has been used to identify the various currents as follows: Identification (unchangeable)

23. The Service menu item “Create Programs” has been renamed “Reset Programs”. 24. The NE menu items “Single-plate and split NEs” and “Split NEs only” have been changed from a program-specific setting to one that applies to all programs. However, this does not apply to the separate (independent) item “Baby NE allowed” – which continues to be a program-specific setting. 25. Connected NEs are now classified by the software, with the consequence that a valid nonsplit NE can become a non-valid one. This is a new feature, as displaying a non-valid (i.e. red) single-surfaced NE was not possible previously. 26. The acoustic activation signals have been reversed in pitch: Cut is now high-pitched, whereas Coag is lower-pitched. This reversal is a concession to market conventions, as many users are accustomed to this sound regime from working with competition products. However, it is possible to change this via the Service menu, so “dyed-in-the-wool” KLS Martin customers can easily retain their customary sound scheme. 27. The Service menu offers four different activation tone sets or “sound schemes” allowing users to distinguish acoustically not only between monopolar and bipolar, but even between all 8 channels (e.g. B1 Cut vs. B2 Cut): V 5.0

107

KLS Martin maxium® / maxium® Beamer Service Manual Sound scheme 1: This is the new default tone set: Cut = high pitch, Coag = lower pitch, plus pitch difference between monopolar and bipolar, i.e. 4 different activation signals altogether. Sound scheme 2: Same as scheme 1: Cut = high pitch, Coag = lower pitch, but no pitch difference between monopolar and bipolar, i.e. 2 different activation signals altogether. Sound scheme 3: Same as scheme 1, but additional differentiation between M1 and M2, B1 and B2, and monopolar and bipolar, i.e. 8 different activation signals altogether. The difference between Bipol Cut B1 and B2 has been made particularly noticeable in response to user requests. Sound scheme 4: “Martin Classic”: Coag = high pitch, Cut = lower pitch. This setting corresponds to the previous maxium® sounds used up to software status V1.357, as well as to the delivery status of all units with hardware versions up to HW03 inclusive. This means that all KLS Martin customers get back their familiar activation signals. This function is also available after updating the software. In this case, however, it is necessary to reselect sound scheme 4 (in a one-time action) if the user wishes to work with the familiar KLS Martin setting, due to the fact that sound scheme 1 is now the new default setting at the time of delivery. 28. The total number of activations is now registered and displayed in the activation log headline. 29. With this software version, PC simulation is now available for the ME402 by way of a program that allows displaying all maxium® functions on a personal computer in a manner sufficiently true to detail. This program can be used for graphics dumps (for inclusion in the user manual and marketing literature) as well as for training purposes (using video beamer) or for “virtual” hands-on exercises without the hardware. Screen dumps are available in original quality with genuine color rendition. The images can be easily copied to a file or to clipboard. No PC installation is required for this purpose because the simulation program can be run directly.

First release for HW05 units. Installation ex factory in units with serial end numbers 071593 to 071795. The new software offers the following new functions, compared with 2.360: •

Recognition of the new hardware version HW05.

108

V 5.0



This is the first software version that is no longer backward-compatible with previous ME402 standard hardware versions as delivered, due to the need for a program memory extended to 2 MB (flash ROM). Hardware conversion from 1 MB to 2 MB was implemented in the HW01 series by way of upgrading the controller board I (C40-1926) to version V06. All HW02 units were shipped with the new controller board II (C40-2217) – which always offers an expanded memory of 2 MB – already in place. Upgrading the controller board I to 2 MB is basically possible but must be done at the factory. However, as this step alone would not be sufficient for utilizing all of the new functions offered by the new software (meaning that additional hardware resources would be required), updating the software to V1.346 might be the better (more cost-effective) alternative. Update for units with hardware statuses HW02 to HW05 Installation ex factory in units with serial end numbers 071796 to 082299 This software offers the following new functions, compared with 2.361: 1. New function “maxiumPC”. The maxiumPC program enables users to simulate the maxium® on a PC, so that all operating/control functions of the maxium® are available for use just as with the real unit. User-specific programs set up with maxiumPC, as well as user settings, can be transferred from the PC to the maxium® via the RS232 interface – and vice versa if users wish to save such programs or settings or copy them to another maxium® unit. 2. New function “Back2Back”. Allows programs and settings to be transferred from one maxium® unit to another via the RS232 interface.

First release for HW06 units. This version is not backward-compatible with previous hardware versions! Installation ex factory in units with serial end numbers 082300 to 082410. This software version offers the following improvements and new functions: 1. New bipolar TUR currents for resection in saline solution using bipolar current. This includes the following currents: Uro Bipol Pure Cut with and without booster pulse: Bipolar cutting currents with low hemostasis for use with resectoscope in saline solution. The intensity of the cut can be controlled via 5 different grade settings, which means that power setting differs from that used for monopolar TUR currents. To facilitate starting the cut upon activation, the HF output power can be temporarily increased (“boosted”) by periodic pulses. If 10 successive pulses have elapsed but the cutting process still has not been started, current activation is automatically stopped and a warning signal sounded. This current can also be used without the booster pulse function. Uro Bipol Blend Cut with and without booster pulse: Bipolar cutting currents with increased hemostasis for use with resectoscope in saline solution. The intensity of the cut can be controlled via 5 different grade settings, which means that power setting differs from that used for monopolar TUR currents. To facilitate starting the cut upon activation, the HF output power can be temporarily increased (“boosted”) by periodic pulses. If 10 successive pulses have elapsed but the cutting process still has not been started, current activation is automatically stopped and a warning signal sounded. This current can also be used without the booster pulse function. Bipol TUR Coag: Bipolar coagulation current for hemostasis with resectoscope in saline solution. An HF output power presetting of up to 180 W is conventionally used. These currents represent an extra option available only against an extra charge, which is why special release is required. To this end, our Logistics department creates a release code for each unit based on its serial number. To enable the bipolar TUR function, users have to enter this code via the text editor. 2. Improved currents for polypectomy and papillotomy. As the usual power setting procedure is rather impractical for these currents, the cutting intensities are now controlled via 5 different grade settings. In addition, the short cutting phases are now process-controlled (whereas they were previously subject to a rigid time regime). These currents are characterized by alternating coagulation and cutting phases. Upon activation, the whole process starts with a coagulation phase. This setting can be globally reversed for these currents via a new submenu item in the Service menu. However, the default setting still starts with a coagulation phase. 3. Additional selection of the footswitch as an activation source for bipolar Auto Start currents is no longer possible. 4. The maximum argon flow setting can now be globally limited to 3.0 l/min via the new submenu item “Endo Flow” in the Service menu.

If the unit has been turned off with a non-saved setting (characterized by the notice “modified” in the program-name text line of the screen), it will not be immediately ready for operation after switching it on again. Instead, a message will be displayed alerting the user to the fact that the currently loaded setting differs from the last-used one. The user is then required to confirm this information by pressing the rotary switch. This change is designed to prevent accidental changes in settings (e.g. in the event of power failure). If the unit has been switched on as a result of voltage recovery after power failure (and not with the power switch), this will be indicated in line 2. 6. Swedish has been integrated as an additional interactive language. 7. HW06 now offers two equivalent bipolar outputs, thus allowing instruments with finger switches, instrument recognition function and port expansion function to be connected to both bipolar outputs. However, this software version still does not support the instrument recognition and port expansion functions. 8. If the application status of the neutral electrode changes from “OK” (green) to “alarm” (red), the system now sounds two short alerts if no current has been activated. The alarm sounded if HF activation is attempted remains the same as previously. 9. In the event of Argon Beamer problems, a short alert is sounded even if no HF current has been activated. If the gas flow is obstructed, the HF current is now blocked as well. 10. If central gas supply is used, the filling level indicator now no longer displays any intermediate values – just “full” or “empty”. The filling pressure for the full gas cylinder no longer needs to be “taught in”; instead, it can now be selected across a range of 200 bar to 140 bar. 11. This software includes an updated software version V3.8 for the Argon Beamer. Updating takes place automatically as soon as the Beamer has been connected to the maxium®, provided the Beamer already has a bootloader. 12. The activation log has been extended to more than 2,000 entries. Moreover, the error and activation logs are now no longer deleted when updating the software. 13. As a corresponding maxiumPC program is also available for this software version, the activation and error logs can now be read out and stored in a PC. 14. Two faults detected in SW2.368 have been removed.

Replacing Modules and Components on the ME402

This section explains how to dismount and reinstall the components of the ME402. Special aspects are discussed where applicable in this context. The numbers given in parentheses relate to the spare parts lists provided in section 5, with several numbers referring to the different socket modules. First thing with any unit is to clarify the hardware status. Specific differences between the various hardware releases are highlighted as well.

6.1

Opening and Closing the Unit

1. Before opening the unit, disconnect power supply cable. 2. Remove the two screws located at the front of the housing bottom (at bottom edge of cover), then remove the two screws located at the top of the rear panel. 3. Withdraw housing top (1) backwards. 4. To close the housing, slide housing top (1) in place from the rear, inserting it correctly into the groove provided in the front part (20) and into the two slots on the rear. Be sure to slide top forward as far as it will go. 5. Reinsert the two screws at bottom front (bottom edge of cover) and the two screws at top of rear panel, but do not tighten them until all four screws have been inserted. Place the unit on a level surface to check that the reassembled housing is distortion-free. Take care that the screws are mounted complete with contact washers. These washers ensure that the cover has proper protective conductor contact. 6. Thereafter, perform the safety checks specified in section 10.

Lift front part and remove it forwards. 9. To reinstall the front part of units up to HW03, first connect the cable of the lower fluorescent tube to X6 on the bottom left of the controller board’s component side. To this end, the cable must be run underneath the bottom edge of the board. If necessary, remove the board from its guide rails and reinstall it with the cable connected. With units from HW04, the fluorescent lamps are connected to the front board. 10. Connect the NE socket to X9 and the shield to X14 on the main board. 11. Swing front panel upwards, engaging it with the bottom edge of the housing bottom (2). 12. Connect the cable from the choke on the main board to X9 of the monopolar socket module. Then put the insulating cover (49/59/69) in place on the socket module, making sure that the three spacers on the socket module engage with the holes provided in the insulating cover, with the cable leading to the choke being guided out downwards. 13. Connect the screen connecting cable to X2, the front board connecting cable to X4 and, for units up to HW03, the upper fluorescent tube cable to X5 on the controller board. 14. Connect the cables of the two bipolar sockets to connectors X3 and X4 on the bipolar board. 15. Screw front part to housing bottom on left and right. 16. Close unit as described in section 6.1, then perform safety checks.

6.3

Replacing the Socket Panel

To satisfy different markets, the ME402 comes with one of three different socket panels. If the unit must be converted to adapt it to a different system, we recommend exchanging the entire socket panel. 1. Open the unit as described in section 6.1, then remove the front part following the instructions given in section 6.2. 2. Disconnect cable (25) – which connects the front board to the activation indicator board – from the activation indicator board (77). 3. Disconnect the membrane keypad’s flexible cable from X5 on front board. 4. Disconnect cable (26) – which connects the front board to the NE status indicators – from the small indicator board (78) which carries the LEDs. 5. Remove the six screws with which the socket panel is fastened to the front frame, then remove the socket panel from the front panel. 6. Attach new socket panel from the front and fix it in place with the 6 screws. 7. Connect the membrane keypad’s flexible cable to X5 on the front board. 8. Reconnect connecting cables to activation indicator board and NE status indicator board. 9. Reinstall front part as described in section 6.2, then reconnect unit as specified in section 6.1. Thereafter, perform functional check and safety checks.

6.4

Replacing the HF Output Sockets

As an alternative to replacing the entire socket panel, individual sockets can also be replaced in case of wear or defect. However, this only applies to the bipolar sockets. As the two monopolar sockets form an integrated connection unit (43, 53 or 63), they must always be replaced together. 1. Open unit as described in section 6.1, then remove front part as described in section 6.2. 2. Remove the screws of the defective socket, then take out the socket or socket module. 3. Insert the replacement part. Be sure to insert the monopolar socket module in the correct position – the HF power supply connector must be on the inner side. Transfer the plastic supports of the insulating cover from the old part to the new one. In the case of the B2 bipolar socket of the “m” (KLS Martin) version (45), it is important to ensure that the outerring cutout is located at the top. In the case of the 4-mm B2 bipolar socket of the “i” version (55), the additional control contacts must be located on the outside, not the inside. 4. Reinstall front part as described in section 6.2, then reconnect unit as described in section 6.1. Thereafter, perform functional check and safety checks.

6.5

Replacing the Socket Module Indicators and Backlights

The channel-selector and NE-status indicators consist of light-emitting diodes whose light is transmitted through the socket module carrier to the front by (molded) transparent plastic parts. While defective plastic light guides can be replaced individually, LED failure requires replacement of the whole board. From hardware version 02, the connector between the activation indicator board (77) and the socket backlight board (80) has been changed. Therefore, it is no longer compatible with old boards (HW statuses 00 and 01). Only the new version is available as a spare part. Therefore, both boards must be replaced in the case of HW00 or HW01 units. From HW04, the light guides and the LEDs have been changed to surface-mount style (SMD). 1. Open the unit as described in section 6.1, then remove the front part following the instructions given in section 6.2. 2. If the NE status indicator is defective, disconnect cable (26) from the NE status indicator board, then remove the screws and the board (and if necessary, the plastic light guide). 3. If an activation indicator or the socket backlight is defective, the “m” and “i” versions require removal of the socket module carrier as described in section 6.3 before you can remove the socket backlight board (80). This is also necessary for replacing the activation indicator board (77) because both boards are connected to each other. If you need to replace the socket-illumination light distributor (42, 52, 62), all boards and all sockets must be taken out (see section 6.4). 4. During reinstallation, be sure to insert the plastic light guides correctly into the socket module frame. The plastic light guides for the activation indicators (48, 58, 68) are identical for all versions, whereas the plastic parts for the NE status indicators are different for the “m” and “e” versions (47, 67) on the one hand and the “i” version (57) on the other hand. As all of these components have an asymmetrical light exit, be sure to verify from the front

In units with HW statuses 00 and 01, install the activation indicator board (77) first and then the socket illumination board (80). When mounting the latter, be sure to insert the 2-pin connector correctly into the socket provided on the activation indicator board. With the new board versions, it is the other way round: here, you must first install the socket illumination board (80) and then the activation indicator board (77). Finally, install the socket module carrier in the front frame, proceeding in accordance with the instructions given in section 6.4. 5. If applicable, connect the flexible cable of the channel-selector membrane keypad to X5 on the front board, then reconnect cable (25) to the activation indicator board and cable (26) to the NE status indicator board. Finally, reinstall front part as described in section 6.2. 6. Reconnect the unit as described in section 6.1, then perform functional check and safety checks.

1. Open unit as described in section 6.1, then remove front part as described in section 6.2. 2. Disconnect the connecting cable from connector X2 on the front board. 3. Remove the two fixing screws with which the unit is mounted on the front frame, then take out unit backwards, thereby disconnecting the LED/backlight board (79) from ring (34). If you need to replace this board as well, first disconnect cable (27) from the board. 4. If you do not need to replace the entire unit, continue by taking out the rotary button (32) backwards with your fingers. This requires application of some force. 5. Use a screwdriver to loosen the screw located at the front of hub (33), then remove the hub from its shaft. Thereafter, remove backlight ring (34) together with rubber ring (90). 6. Use a wrench to loosen the bearing bush (35) with which the rotary switch is screwed to fixing bracket (36). 7. During reinstallation, begin by mounting rotary switch (31) to fixing bracket (36), together with bearing bush (35). Be sure to position the grounding cable connector correctly.

Place rubber ring (90) over the collar of the bearing bush, then put backlight ring (34) on top so that the surface offset towards the inside is located on the upside. 9. Place the plastic hub (33) on the shaft, then slide it downwards as far as it will go and tighten the front screw. Subsequently, install the rotary button (32), inserting it as far as it will go. 10. If required, change the grounding cable from the old part to the new one. 11. Insert the rotary switch unit into the front part. As the switch projects from the frame, place the front part so that the region of the switch is “free-standing” (e.g. let this part project over the edge of the table or support on which you place the front part with its front surface down). Rotate the backlight ring so that the straight part of its edge is on the upside (aligned horizontally). With units up to HW03, the LEDs of the backlight board (79) have to be inserted into the three bore holes; with units from HW04, the three pins of a small plug connector (pin header) are used for board fixation. The board is not fixed in place separately, but is only supported by a vertical bar molded to the front part that prevents it from falling back out after installation. Mount the fixing bracket to the front frame with the two screws. Note that in units with HW status 00 or 01, the lower of the two screws is used also for fastening the grounding cable (18) which has its own connector on the fixing bracket in units from HW02. Reconnect the rotary switch cable to X2 on the front board and (if applicable) cable (27) to board (79). 12. Before installing the front part, check that the switch can be rotated freely and that the axial switching function (“axial click”) has a clear action point. 13. Reinstall front part as described in section 6.2. 14. Reconnect the unit as described in section 6.1, then perform functional check and safety checks.

6.7

Replacing the ON-OFF Button

The ON-OFF button (22) is not a power switch but simply a button transferring a control signal to the standby interface of the power manager board. 1. Open unit as described in section 6.1 and disconnect front part as described in section 6.2. It is enough to disconnect the upper cable connectors and tilt the front part a little forward. 2. Disconnect the button cable from connector X4 on the front board (top), then press the button out of the front part from the rear. 3. Insert the new button (22) into the front part from the front, ensuring that the centering lug points upwards, so it can engage with the corresponding slot provided for this purpose in the opening of the front part. 4. Reconnect cable to connector X4 on front board (76). 5. Reinstall front part as described in section 6.2. 6. Reconnect the unit as described in section 6.1, then perform functional check and safety checks.

6.9

Replacing the Screen Module and the Protective Glass Pane

The screen module (75) should be replaced in a dust-free environment to prevent any unwanted particles between the screen and the protective pane (21). To prevent the screenmodule and protective panes from getting electrostatically charged, we recommend placing them on a clean, antistatic surface (e.g. covered with a soft, lint-free, natural-fiber cloth). When handling the screen module, be sure to observe the working guidelines relating to ESDsensitive components. Unlike the other electronics components, the screen module cannot be repaired and, therefore, is not available as a (refurbished) exchange part. 1. Open unit as described in section 6.1 and disconnect front part as described in section 6.2. 2. Remove front board (76) as described in section 6.8. 3. Disconnect the four screws that attach the screen module to the front part. The screw located next to the connecting cable connector is used also for fastening the electrical connection required for shielding the module. Remove screen module upwards and disconnect connecting cable (23) if necessary. 4. If you just need to replace the fluorescent tubes, unlock the black plastic clips (lifting them a little), then withdraw the tubes longitudinally. Insert the new tubes fully, making sure that the plastic clips engage correctly. 5. If you want to replace the protective pane, remove the inner gasket, then take out the glass pane (complete with its outer seal) by pressing it inwards. 6. Before installing the new pane, check it for cleanness (no dust or finger prints!). If necessary, clean it with a soft cloth. 7. Place the protective glass pane on a clean, antistatic surface with its outer surface upside, then put the new, soft external gasket supplied in place on the glass pane (around the shoulder or inner part). Verify that the rounded-off edge of the outside contour of the protective pane is upside, whereas the bottom edge is not rounded off – so the glass can only be installed in this way. Insert both components into the front part from the inside (hold front part over the glass pane thus prepared, with its outer surface upside). Take care not to touch the glass surface with your fingers when doing this (we recommend using a piece of cloth or wearing gloves). Then turn the whole assembly around and check that the external seal is correctly in place on the shoulder of the glass pane and does not protrude underneath the glass. 8. Install the dark inner gasket on the inner side of the protective pane, then put the screen module in place, installing it straight/perpendicularly from above and fitting it to the front part with the four screws. Note that the tube connectors must be on the side of the HF output sockets. The screw next to the connector is used also for connecting the shield (in units up to HW03: the cable lug of connecting cable (23); in units from HW04: a separate cable). Connect cable (23) to the plug connector.

Replacing the Controller Board

The controller board (71) stores the user settings. As far as possible, therefore, these settings should be saved prior to replacing this module, or loaded down as described in section 4. When handling the controller board, be sure to observe the working guidelines relating to ESDsensitive components. This board is available as a (refurbished) “exchange part”. Spare or replacement parts are shipped with the most recent software available, so no update is required. 1. Open unit as described in section 6.1. 2. Unlock the controller board by removing the locking pins located at the upper ends of the support rails. 3. Disconnect the serial interface cable (8) from X10 and the front-board connecting cable (24) from X4. 4. Disconnect the cables of the two footswitch sockets (5) and (6) from X8 and X9. 5. Disconnect the screen-module connecting cable (23) from X2 at the controller board. With units up to HW03 (controller boards I and II), this connector is located on the board’s rear side. If necessary, loosen the screws of the front part according to 6.2 and tilt the front slightly forward to get better access to the connector. 6. With units up to HW03, disconnect the connecting cables of the fluorescent tubes from the connectors X5 and X6. To disconnect the lower tube’s cable from the connector X6 at the board’s lower edge, pull the board a little upward in its rails, then withdraw board upwards. X4

7. Prior to installing a new board of version I or II, check jumper X500 for correct position. If necessary, set it to the same position as used with the old board (concerns adjustment to Erbe footswitch). With units up from HW04, check the jumper array X3 and configure X3 of the new part in the same way as X3 on the old part. 8. For reinstallation in units up to HW03 (with controller board I or II), start with inserting the board into its supporting rails, then connect the cable of the lower fluorescent tube to X6 first. The cable must be routed underneath the bottom edge of the board to the connector located on the upper side. Note that the connecting plug is not rotationally symmetric and can only be inserted in one position. Thereafter, with units of up to HW03, connect the screen-module cable (23) to X2 on the board’s rear side, then press the board downwards in its support rails and lock it with the locking pins provided at the upper ends of the rails. If necessary, screw front part in place again. 9. Reconnect the cables of the two footswitch sockets (5) and (6) to X8 and X9, respectively. As the cable connectors differ in pin number, misconnection is prevented. 10. Connect the connecting cable of the upper fluorescent tube to connector X5 (units up to HW03 only), the serial interface cable (8) to X10 and the front-board connecting cable (24) to X4. Since the serial interface cable also fits X4 in units up to HW03, it is important to ensure a correct match to prevent misconnection. 11. With units up from HW04 (controller board III), connect the flexible flat connector from the screen to X2 on the component side. For this purpose, the connector is to be guided around the support rail. Take care that the flat connector is not subject to mechanical stress or kinked in the plug area. 12. The controller board has no adjusting positions. Before closing the unit, reconnect the power cord and verify that the unit is operational. Thereafter, disconnect power cord again. 13. Reconnect the unit as described in section 6.1, then perform functional check and safety checks.

Reinstall front part as described in 6.2 and controller board (71) as described in 6.10. 14. Reconnect the power cord and verify that unit is operational. Although there are no adjusting positions on the main board, the basic power setting as well as the transfer characteristic of the optical link must be checked – and adjusted if necessary – if the main board has been replaced (for power setting, see section 10.2; for optical link adjustment, see section 10.3). Thereafter, disconnect the power cord again. 15. Close the unit as described in section 6.1, then perform functional check and safety checks.

6.15

Replacing the Footswitch Sockets or Loudspeakers

If one of the footswitch sockets (5) or (6) or the loudspeaker (10) is defective, the entire module complete with connecting cable must be replaced. 1. Open unit as described in section 6.1. 2. Remove front part as described in section 6.2 and controller board (71) as described in section 6.10. If required for better access to the defective module on the rear wall, remove power manager board (72) as well (see section 6.11). 3. Disconnect the cable of loudspeaker (10) from connector X8 located on the right at the front of the main board. 4. Using a size-7 socket wrench, remove the eight self-locking nuts that hold the main board to the housing bottom. Lift the board a little on the right side so the bunch of cables located underneath can be pulled out more easily. 5. Cut the cable fasteners holding the cables together, then disconnect the connecting cable of the defective module and dismount the latter from the rear wall. In the case of the small footswitch socket of HW00 and HW01, you need a special tool to do this. However, the threaded ring that holds the socket in place (sometimes two rings were used, one on top of the other) can also be removed with a normal screwdriver – just insert the blade into one of the slots and – instead of rotating the screwdriver – apply counterclockwise tangential pressure to the ring. Spare parts feature a hex nut which is easier to mount. As from hardware status 02, the loudspeaker comes mounted on M3 threaded bolts with insulating nipples. 6. Install the new module on the rear wall. In the case of the small footswitch socket, place the part into the mounting hole, pull the cable through the hex nut and screw nut in place on the socket. Be sure to meet the plastic fine pitch thread correctly (no jamming!) and do not tighten too much. Take the connecting cable to the right and combine it with the two other cables. Install the loudspeaker in the same way as you removed it. 7. Lift the main board a little on its right, place the cables underneath it and lay them out behind the stay-bolts in such a way that they can be easily routed upwards, without getting

Replacing the Power Supply Socket, the Serial Interface Unit or the Argon Beamer Connector

The power supply socket (3), the serial interface unit (8) and – in units with HW status 01 or higher – the connecting socket for the maxium® Beamer (7) are all located on the rear panel of the unit and can be replaced without any need to remove the main board. 1. Open unit as described in section 6.1. 2. If better access to the defective part is needed, remove power manager board (72) as well (see section 6.11). 3. If you need to replace the power supply socket (3), disconnect the main-board connecting cable (15) and the protective conductor (PE). Remove the two fixing nuts, then remove the socket inwards. When installing the new socket, do not forget to transfer the fuse holder (4) from the old part to the new one. 4. If you need to replace the serial interface unit (8), remove the four nuts and withdraw the unit inwards. When installing the new unit, ensure that the male DSUB9 socket is located on the left (towards the power supply socket) and the female DSUB9 socket is located on the right (footswitch socket side). 5. If you need to replace the Argon Beamer connecting socket (7), begin by disconnecting the cables from connectors X2 and X21 on the main board. With HW01 units, this socket is still mounted by way of a threaded ring (sometimes even two rings are used, one on top of the other). A special tool is usually needed to remove the threaded ring(s). However, you can also use a normal screwdriver. Just insert the blade into one of the slots and – instead of rotating the screwdriver – apply counterclockwise tangential pressure to the ring. Spare parts are provided with a hex nut which is easier to mount. Insert the new component into the opening from the outside, then guide the two connectors and the PE terminal through the nut and screw nut in place on the socket, taking care to introduce the plastic fine thread correctly (no jamming). Do not overtighten! Fix PE conductor cable in place on the rear wall, then reconnect the two cable plugs to X2 and X21 on the main board. 6. Reconnect the power cord and check that unit is operational, then again disconnect mains cable. 7. Close the unit as described in section 6.1, then perform functional check and safety checks.

Technical Description of the ME402 with MB402 Option

7.1

General Information

The Martin ME402 maxium® is a universally applicable high-frequency (HF) surgical unit satisfying all requirements of clinical users as well as specialized private practitioners. As an accessory, the Argon Beamer MB402 is available, which has been specially optimized for use with the ME402 maxium® and is completely controlled via the latter. Both units and the gas cylinder can be conveniently installed on the maxium® Cart, a special equipment trolley. Compared with its predecessors, the ME402 has been upgraded with a range of new features, especially the following: •

Wide-range power supply unit for supply voltages of 100 VAC to 240 VAC, 50 Hz to 60 Hz.

•

Operation through an 8.4-inch TFT color screen with background illumination (provided by 2 fluorescent tubes).

•

Selection of numerical values via rotary switch with axial switching function and channel selector buttons.

•

Novel operating concept taking ergonomic aspects into account.

•

Two equivalent monopolar HF outputs that can be activated either by finger switches (pushbuttons) on the electrode handle or by a freely assignable footswitches.

•

Neutral electrode monitoring with on-screen indicators.

•

Two bipolar HF outputs – one activated with a freely assignable footswitch or by impedance-dependent automatic control; the second activated with a freely assignable footswitch, or by impedance-dependent automatic control, or with the instrument’s finger switches. This second output features an instrument recognition function as well. From HW02, it also allows connecting two different instruments – for bipolar cutting and bipolar coagulation – which can be activated separately.

•

Exchangeable socket modules for connection of KLS Martin accessories and US-specific accessories. Besides, an extra version is available for connecting Erbe accessories.

•

Up to 100 settings can be stored as user-specific application programs.

•

The Argon Beamer MB402 (available as an accessory) is completely powered, controlled and activated through the ME402.

•

Serial CAN interface for making the ME402 part of an integrated OR system, as well as for communication with other medical equipment.

•

RS232 serial interface for convenient software updating directly from your PC, for transferring settings and for other servicing purposes.

7.2

Design and Servicing Concept

The bottom part of the ME402’s housing functions simultaneously as a chassis for all the other modules and assemblies. The front part, also fitted to the bottom of the housing, serves as a separate mounting rack (module carrier) for the instrument connecting sockets, the display screen, the rotary switch and the buttons and indicators, plus the associated boards with the electronic components required for their operation. Whereas the large front board is an “exchange part” that can be repaired/refurbished by the manufacturer and is offered at a reduced “exchange price”, the small boards accommodating only the light sources for the indicators and backlights are not available as refurbished parts. The same applies to the TFT screen board. The main board houses the power electronics for the power supply units, the HF current generator and four other modules required for the associated signal electronics. While the latter can only be replaced by the Technical Service, the main board can be both replaced and repaired on the component level (by the specialized dealer or the hospital technician himself). The main board features only the large power electronics components. While it is true that these components have the highest failure probability, checking/testing and replacing them is relatively easy. The Argon Beamer MB402’s main board contains the pneumatic valve block with associated control and regulation electronics including a microcontroller. Moreover, the MB402 has a small front board containing the status indicator LEDs. The PURGE button is also connected to this small board. The MB402 is powered and operated/controlled through the ME402 via a connecting cable attached on the rear side of the unit.

7.3

Functional Description of the ME402

The electronics of the ME402 can be subdivided into the following functional units: •

Power supply units

•

HF generator and HF current paths

•

Monopolar applied part

•

Bipolar applied part

•

Main controller with interfaces

•

Front part

7.3.1

Power Supply Units (PSUs)

From the mains alternating voltage, the power supply units generate the voltages required for the HF generator, the control system and, if connected, the Argon Beamer MB402. In this process, the mains voltage – nominally ranging between 100 V and 240 V, depending on the location – is rectified and brought to a fixed, direct voltage of 390 V. Thereafter, two paralleled stages generate the fixed auxiliary supply voltages of +15 V and +5 V for the main controller and the Argon Beamer, as well as the variable voltage VDC needed for HF generator operation.

KLS Martin maxium® / maxium® Beamer Service Manual The power supply system consists of five units: •

power input,

•

step-up converter with power factor correction,

•

auxiliary supply voltage,

•

power controller,

•

standby interface.

The power electronics part is located in the rear section of the main board. The associated signal electronics are located on the power manager module.

7.3.1.1 Power Input The mains input circuit has four tasks: •

Limitation of the transient inrush current after connecting the unit to the power supply system in order to prevent the network installation’s protective devices from being tripped (inrush restraint);

•

internal voltage limitation in the event of overvoltage (caused e.g. by lightning);

•

cutting off short-circuit currents caused by faults;

•

limitation of internal interference voltages to the legally prescribed maximum value. X1.1

to PFC stage

X1.2

Mains inlet

Main Board

Limitation of the transient inrush current is ensured by NTC thermistors (resistors) located on the main board. For overvoltage limitation, a voltage-dependent resistor (VDR) is provided on the main board. The fuses for fault-current interruption have a nominal value of T6.3A (6.3 A slow-blow) and are located in the power supply socket for the detachable power cord. The filter assembly for limiting the interference voltages generated by the unit consists of a filter integrated into the connecting socket for the power cord and filter components integrated into the power input circuit on the main board.

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.1.2 Step-Up Converter with Power Factor Correction The step-up converter rectifies the alternating voltage supplied by the mains and generates a direct voltage of 390 V independent of the line voltage. The main components of the step-up converter are the rectifier V1, the choke L3, the switching transistor V2, the diode V3, the capacitor C8 and the resistor R4. Upon switching on transistor V2, choke L3 is charged by the rectified mains input current. Upon switching off V2, this current is redirected to diode V3, charging the capacitor C8. At C8, the voltage DC+ achieves a value that exceeds the peak value of the mains input voltage. This process is repeated periodically at a frequency of approx. 100 kHz. The voltage at C8 can be regulated by varying the switching-on/switching-off ratio (i.e. the duty factor) of V2. This is done by a regulator located on the power manager module (pulse width modulation, PWM).

This voltage regulator also features an internal control loop that controls the mains power input so that it is proportional to the mains voltage. In this process, the actual-value signal of the power input current is picked off at resistor R4. As a result, the unit responds like a resistive load connected to the line and does not generate the power input harmonics that are otherwise typical for devices having a rectifier as part of their power input circuit (power factor correction). At a high power output, the cos ϕ is 1; in non-activated condition (with unit ready for operation, i.e. in standby mode), this value is lower due to the reactive current of the filter capacitors in the mains input circuit. A fast-discharge circuit ensures that C8 is discharged within 10 seconds to a non-dangerous level as soon as the unit is disconnected from the supply voltage. As from hardware version 02, a red LED B1 lights up if C8 is energized. The auxiliary supply voltage VH for the signal electronics and the drivers of the mains-circuit power transistors is provided by an auxiliary winding of choke L3. A green LED “VH” located in the upper left section of the power manager board indicates presence of voltage. As this circuit supplies power only after the step-up converter stage has built up, a starting circuit is provided as well which, through a high-ohmic resistor, charges a capacitor directly from the rectified

KLS Martin maxium® / maxium® Beamer Service Manual mains voltage. The energy of this capacitor is then used to bridge the time interval until the auxiliary circuit takes over power supply at L3. This explains why it takes a few seconds for the unit to be turned on with the button located on the front panel following connection to the mains. This time interval is greater if the unit is connected to a 100-V supply network, compared with operation on the basis of 230-V power supply. If the line voltage drops below 85 V, the unit can no longer be turned on. In the event of a step-up converter fault, the device fuses located in the power supply socket assembly will be blown. The main board component with the highest failure probability is the transistor V2, due to line-side overvoltages or overload due to a fault in downstream stages.

7.3.1.3 Auxiliary Supply Voltage To generate the supply voltages required for the control and signal electronics, the transformer T2 is operated with the prestabilized direct voltage “DC+”, protected by a fuse F1 (M0.125 A), via an inverter half-bridge consisting of the transistors V4 and V5 connected in series with R15 plus C9 and C10. This half-bridge is controlled through the power manager module, which also hosts the rectifier and the controller for the secondary circuit of T2. Current limitation is ensured by V5, which measures the current at R15.

The power manager module generates the auxiliary supply voltages of +15 V and +5 V from the medium-frequency secondary voltage of T2.

Through a second secondary winding, the transformer T12 (main board) is powered for auxiliary supply of the monopolar patient circuit (MAC pair of signals). A short in the auxiliary supply circuit blows the F1 fuse. The components with the highest failure probability are transistors V4 and V5 (with pair-wise/simultaneous failure most of the time), the power-manager-module rectifier and the downstream constant-voltage regulators or converters, including those on the main controller module.

7.3.1.4 Power Controller To generate the operating voltage for the HF generator, the transformer T6 is operated with the prestabilized direct voltage DC+ present at C8, protected by a fuse F2 (M1.6 A) via an inverter half-bridge consisting of transistors V6 and V7 plus capacitors C11 and C12. This halfbridge is controlled via transformers T4 and T5 from the intermediate circuit side of the power manager module. The current transformers T7 and T8 capture the current flowing into this half-bridge. The secondary side of T6 features a rectifier consisting of diodes V8 and V9 plus L5 and C13. At C13, a direct voltage (VDC) can be set across a range of 0 V to 180 V.

main controller board The output level of this power controller is set by one of three regulators (up to HW03), or by one of four regulators (from HW03), whose open-collector outputs act upon a joint pull-up resistor at the control input. The first regulator regulates the output voltage VDC to a level defined by the main controller’s signal USO, its actual value being identical with the direct current voltage (VDC) at C13. When this (first) regulator is active, the red LED designated “UR” lights up on the power manager module. This is the case with some coagulation currents as well as in no-load operation or in the event of mismatch (if required parameters are not achieved by other regulators). The second regulator controls the current flowing into the power controller to a level defined by the PSO signal. Its actual value is generated by current transformer T8. As the power controller operates on a prestabilized voltage, its input current is identical to the direct-current input power supplied to the controller. This power input, in turn, represents the sum of internal losses plus HF output power. Which means that under conditions of reproducible internal losses, the current actual value signal I1 is a measure of the actual value of the HF output

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual power. When this (second) regulator is active, the green LED designated “PR” lights up on the power manager module. This occurs with most currents when operated in the nominal load range. The third regulator controls the direct-voltage component generated between the electrode and the patient during the cutting process, and superimposed on the HF voltage, to a predefined value. This DC component is indicative of the type of electrosurgical cutting process generated as a result. The controller is located on the monopolar module, where it receives the actual value “DCI” from a sensor circuit and the reference or setpoint value “DCS” from the microcontroller on the monopolar board, which in turn receives it from the main controller. For details, refer to section 7.3.3.2. The control deviation (or error) signal is optically transmitted to the power manager module via a plastic fiber (waveguide), and the receiver amplifier acts upon the control input, just as the two other regulators do. When this (third) regulator is active, the yellow LED designated “FR” lights up on the power manager module. This only happens when monopolar cutting currents are used. From HW03 onwards, there is a second regulator in parallel to the DC regulator, intended for limiting the HF output voltage especially at no-load. The corresponding setpoint “ACS” is supplied by the microcontroller on the main board, which in turn receives this input from the main controller. For details, refer to section 7.3.3.2. The control deviation (or error) signal is optically transmitted to the power manager module via the same plastic fiber as used for transferring the DC regulator signal. When this (fourth) regulator is active, the yellow LED designated “FR” lights up on the power manager module as well. On the monopolar board, the red LED “ACR” lights up if the AC regulator is active, whereas the yellow LED “DCR” lights up if the DC regulator is operative. The power controller is activated by the main controller with the signal “DCEN”. Through the signal “PPK”, the main controller can briefly set the power controller to maximum to achieve a transient output power overshoot. In the event of shorts or overload, the F2 fuse is blown. The components with the highest failure probability are diodes V8 and V9 on the main board, caused by a short in the HF generator or by overload abuse. This can subsequently lead to failure of transistors V6 and V7 (usually affecting both).

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.1.5 Standby Interface A button located on the front panel turns the ME402 on and off in the sequence of button operation. An interface circuit stores the on or off status, thus isolating the pushbutton circuit from the mains for safety reasons. The auxiliary transformer T1 supplies the mains-isolated current for pushbutton operation. The button signal is transmitted to an asymmetric flip-flop in the mains circuit via an optocoupler located on the power manager module. The flip-flop in turn controls an enable input of the PFC controller. In this way, the step-up controller – and with it the generation of primary auxiliary supply voltage for the downstream stages – is switched off, while the mains voltage continues to be present on the primary sides of these stages.

In the first hardware versions (01 and 02), this flip-flop always returns to reset state following disconnection from the mains, which means that the unit remains switched off after a power failure. As from hardware version 02, the flip-flop maintains its current state for approx. 5 seconds, so the unit remains on if the power supply is briefly interrupted and no restart is required. The power manager module features a jumper X10 (underneath the protective cover) that allows disabling the flip-flop by setting (replugging) the jumper to the 2-3 position. This can be useful for servicing and performing the technical safety checks.

7.3.2

HF Generator

The electrosurgically effective high-frequency current is generated in a full bridge consisting of transistors V10, V11, V12 and V13, which is powered by the power controller’s VDC output voltage and acts upon one of two output transformers. The relays K2 and K3 switch the voltage to one of two different primary windings of the monopolar output transformer T11, which allows low- to medium-ohmic or high-ohmic output adjustment. The relays K4 and K5 switch the output of the bridge to the primary winding of the bipolar output transformer, either directly or via a series capacitor. The bridge is driven by the two main-board switching amplifiers N1 and N2, supported by transformers T9 and T10. The main controller module generates signals GT1 and GT2 required for driving the bridge. The signal HFON, from which the control signal TON is generated, is picked off at the output of the control amplifier N2. This signal switches on the acoustic generator on the main controller board, independent of the main controller.

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.3.1 Finger Switch Interface The monopolar outputs M1 and M2 allow connection of electrode handles with finger switches (pushbuttons) for activating the cutting and coagulation functions. These switches relate to the conductor leading to the active electrode. In the KLS Martin handles featuring a circular coaxial plug, two diodes polarized for different conducting directions are connected in series with the switches, so one additional lead suffices for both switches. Differentiation between which of the two switches has been selected is possible by decoding the current flow direction once alternating current has been applied. In contrast, US handles with 3-pin flat connectors have a separate conductor for each switch. Therefore, the monopolar socket module board features two diodes for each of the two connectors. These diodes re-code these 3-pin connectors to adapt them to the Martin format to ensure that both types of handle can be used in the same way. X5.2 X5.1 X4.2

Through optocouplers, the finger-switch activation signals CT1 and CG1, or CT2 and CG2, are transmitted to the NE-side microcontroller. LEDs connected in series with the optocouplers indicate the presence of an activation signal – yellow for cutting and green for coagulation. When using instrument cables with a plain 4-mm connector, misconnection may occur because this plug – which should be inserted into the inner conductor of the coaxial socket – technically fits the adjacent 4-mm sockets for the finger switch signals as well. Such misconnection could damage the finger switch because when the HF current is activated with the footswitch (which is the usual source of activation when using instruments with such cables), the current would be rerouted through the finger-switch control circuit. To prevent damage, HF current flow through the finger switch circuit is monitored. As soon as a critical limit is exceeded, the signal PIN1 or PIN2 is generated and indicated by a red LED. While presence of such a signal is normal in connection with one of the finger switch activation signals, the generator is switched off and an error message displayed if the signal PIN1 or PIN2 occurs alone or in conjunction with a footswitch activation signal.

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.3.2 Monopolar Regulators In electrosurgical cutting, tissue dissection is achieved by a very high power density at the point of contact between the active electrode and the tissue. In this process, water vapor is released from the tissue in the cutting canal, separating the tissue from the electrode (the socalled Leidenfrost effect) so that the current cannot pass unhindered from the electrode to the tissue. Therefore, a correspondingly high electric current is needed to overcome (break down) the insulating vapor layer. In this process, gas discharge occurs inside the vapor layer, whereby the vapor must be ionized to make it electrically conductive. As the energy necessary for this is taken from the electric circuit, this leads to a voltage drop above the vapor layer. Ionization takes place above the surface of the cathode. However, since high-frequency alternating current is used here, the electrode and the tissue alternatingly function as the cathode. This is a highly asymmetrical pair of electrodes, though, leading to varying energetic conditions for the ionization process. For example, it can be observed that the breakdown of the negative half-wave takes place at an apparently lower resistance than that of the positive half-wave. Therefore, the current of the negative half-wave would be greater than that of the positive half-wave, which means that a direct current would be superimposed on the high-frequency alternating current – which must definitely be prevented because it would cause nerve irritation. For this purpose, capacitors C19 and C20 have been included. They build up direct current that is used to shift the HF alternating voltage symmetrical to the zero line (as present at the secondary side of T11) into the positive range to such an extent that negative and positive current half-waves carry the same amount of electric charge.

The same direct voltage builds up between the neutral and active electrodes and is again superimposed on the HF voltage. By capturing the voltage between the output sockets and filtering out the superimposed direct-voltage content, it is possible to arrive at a quantity that can be used as the actual value for cutting canal formation. As this voltage continuously increases along with the increase in the electric power used/applied in the cutting canal, it can be regulated as well. With the ME402, this is the task of the control circuit termed “arc regulator”.

The regulator’s deviation signal controls an LED that serves as the sender side in an optocoupler consisting of a separate sender and receiver and connected to the receiver of the power manager module via an plastic optical fiber. There, the signal acts upon a busbar via an amplifier (the voltage and power regulators acting upon it as well). When using a capacitive neutral electrode on the patient, it is not possible to capture the direct-voltage component, so arc regulation is not possible in this case.

From HW03, the monopolar board features a second HF output voltage regulator at outputs M1 and M2, designed for HF output voltage limitation in no-load condition to reduce the load on connected instruments and minimize HF leakage currents. Apart from measurements for the DC component, there is also an HF voltage measuring path. The PWM output of the microcontroller in the monopolar applied part must be multiplexed in order to obtain separate setpoints for the AC regulator and the DC regulator, formed by downstream PWM demodulators. Both regulators act upon the same LED which, via a plastic optical fiber, transmits the control signal to the power controller located on the power manager board, as described in section 10.3.2. If the HF voltage regulator is active, this is indicated by the red LED “ACR” lighting up brightly (while glowing darkly if the regulator is non-active). The same applies to the “DCR” LED indicating DC regulator action or non-action. The microcontroller of the applied part can bypass these regulators by using the CRB signal to control the LED at the optical link directly. This allows it to switch off the HF output power very quickly.

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.3.3 Neutral Electrode Monitoring The ME402 allows connection of both single-plate and split neutral electrodes. The NE-side HF current path is split on the main board by capacitors C20 and C21, and both paths are then conducted to the NE. The impedance between the two lines is monitored by a monitor consisting of a free-running oscillator whose amplitude is attenuated by the parallel resistance at the NE. In the case of single-plate NEs, the two lines are connected to each other directly at the electrode, so the monitor recognizes a short if such an NE is used (and the cable connection is O.K.), interpreting this correctly as connection of a single-plate NE. Consequently, the singleplate NE symbol appears in green on the unit’s display. It is possible, however, to exclude the use of single-plate NEs via the “Setup” item of the control menu. In this case, a message will inform the user that single-plate NEs are not permitted (disabled by user). As from software version 1.328, the use of small-surfaced baby NEs can be enabled through the setup as well. This limits the output power of appropriate currents to values that allow only smaller NE currents.

If split NEs are used, impedance measurement is possible only on the patient’s skin because the patient closes the monitoring circuit. The alarm is switched off as soon as impedance drops below a limit of approx. 250 ohms and a green split-NE symbol is shown on the screen. Usually, however, impedance is much lower, but the minimum is reached only after a few minutes. The monitor stores this minimum and uses it as a reference value for the alarm decision. Exceeding this minimum by a predefined value triggers NE alarm with the consequence that no monopolar HF current can be generated or power output is interrupted. This ensures NE alarm in cases where the NE detaches from the patient unnoticed – irrespective of electrode or patient skin properties. The unit offers a special graphical indicator informing the user about NE contact quality, i.e. the degree to which it makes contact with the patient’s skin. It has the form of a horizontal bar graph or scale with a slide and three fields in the colors red (alarm range, no HF output), V 5.0

The transmission format of the synchronous serial interface, which serves for communication with the main controller, is equivalent to an SPI bus. Due to the insulation required between the patient circuit and the intermediate circuit, the optocouplers U1…U4 are used to deliver the signals MOSI, MISO, CLK and CSM to the main board. While the sender and receiver circuit of the high-voltage side is found on the monopolar module, the associated circuit of the intermediate circuit side is located on the bipolar module. In normal operation, a yellow LED flashes on the monopolar module at a frequency of approx. 1 Hz. A red LED lights up if communication between the main controller and the patient circuit controller – via the SPI bus – is interrupted. This is also the case during to the main controller’s self-test. A green LED lights up when the main controller is sending an activation command.

KLS Martin maxium® / maxium® Beamer Service Manual 7.3.4.1 Impedance Monitors Parallel to each of the two bipolar outputs B1 and B2, the unit features an impedance monitor that delivers the signal IMP1 or IMP2, respectively. This signal represents the tissue resistance measured between the conductors and serves for controlling the automatic and half-automatic activation of the bipolar coagulation currents having such an auto-function. If a half-automatic type of current (Auto Stop) is activated (by the surgeon), the monitor connected to the activated channel superimposes on the HF current a low medium-frequency voltage that generates a current which in turn serves as a measure of tissue impedance. When starting the coagulation process, tissue impedance typically begins to drop to a minimum, then increases again. If a certain level is reached relative to the minimum, the HF current is switched off. This limit or rise can be set by the user for the various types of current via a submenu. Following cut-off, renewed activation is possible only after releasing the switch and operating it again. In fully automatic operation (Auto Start + Auto Stop), the impedance monitor of the channel for which a bipolar coagulation current with auto-start/auto-stop function has been selected controls the switching-on process as well. The HF current is activated if the resistance between the output poles of the electrode leads drops below a defined value. Switching off follows the same rules as described above for semi-automatic currents with Auto Stop. Activation can be delayed by a certain time factor that can be set via the same submenu as the switch-off level.

The signals IEN1 and IEN2 are used to activate or deactivate the impedance monitors of the outputs B1 or B2, respectively. In these two identical monitors, a multivibrator generates a periodic signal that is fed to the poles of the corresponding bipolar output socket via a filter network. Tissue contact of the active electrode creates a shunt that attenuates the signal. The resulting decrease in the signal’s amplitude (due to attenuation) is then used as a tissue resistance measure. The signal amplitude is determined by rectification; the trimmers IMP1 and IMP2 are used to set the output voltages for operation without tissue contact, with the output signals IMP1 and IMP2 transmitted to the main controller in analog form.

At the same time, the transformers T2 and T3 provide the required electrical isolation between the bipolar applied part and the intermediate circuit in this network. The frequency of the multivibrators must be adjusted to the parallel resonance of the respective filter networks. This is done with the trimmers F1 and F2.

When the Auto Start type of current was implemented with HW02, a monitor with higher sensitivity was required. The monitor signal is now a periodic sequence of groups of individual pulses (bursts) whose instantaneous values are registered via sample-and-hold elements to restore analog DC signals IMP1 and IMP2. Adjustment to the resonance frequency of the filter network is done with the switches S1, S2 and S3 by setting a division ratio by which the monitor frequency is derived from the fixed frequency of a quartz. When activating HF current, the circuit of the HF output transformer T13 (on main board) is connected in parallel to the filter network via C1 and C2 on the bipolar board. This not only changes the resonance frequency of the filter network, but the output signal IMP1 or IMP2 as well. Therefore, the amplification of these signals is switched depending on the position of the output relays – which also explains why the basic setting of the signals IMP1 and IMP2 must be done separately for the open source circuit (OC) and for the closed source circuit (CC). The yellow and green LEDs next to the trimmers indicate the current state of the circuit. With the HF output socket shorted, the trimmers SC1 and SC2 are used to adjust the output signal to a defined value. The operating modes with automatic activation of HF power upon tissue contact pose high risks in endoscopic interventions because unintentional tissue contact is almost unavoidable when placing the instruments in the surgical field. For this reason, the ME402 requires the user to expressly confirm the Auto Start/Auto Stop mode when calling up a program that includes such V 5.0

157

KLS Martin maxium® / maxium® Beamer Service Manual a fully automatic type of current. The same applies if the unit starts up with a program that includes such a current. In fully automatic operation, it is not possible to use a cutting current at the same output because the ME402 cannot differentiate whether the decrease in resistance at the leads has been caused by tissue contact of a coagulation or a cutting instrument. So if a current with Auto Start/Auto Stop is selected, the cutting channel belonging to the same output is switched off. Conversely, the current with Auto Start/Auto Stop is switched off if the cutting channel is reselected with the yellow channel selector button.

7.3.4.2 Finger Switch Interface and Instrument Coding The B2 bipolar output socket also allows users to connect instruments with finger switches that can activate the cutting and coagulation functions, just as with monopolar handles. In the case of the circular Martin socket, the auxiliary contacts required are located on the rim of the socket – which means that the small coaxial plug of the forceps connecting cable does not support this function. The international (“i”) socket module, in contrast, provides an additional 2-mm socket for this purpose, but this requires a corresponding plug with a 2-mm pin, of course. The multifunction socket of the Erbe (“e”) version also allows connection of this plug. An optocoupler transmits the corresponding signals to the intermediate circuit, and from there they are passed on to the main controller as signals BCT and BCG.

KLS Martin maxium® / maxium® Beamer Service Manual In addition, the B2 socket offers a resistance-coded instrument recognition function. If an instrument coded in this way is connected, the system automatically assigns a specific program to this output that optimally serves the instrument. As this function is also controlled through the additional contacts of the B2 socket, instruments with special connecting plugs are required. The pulse width-modulated signal is passed on to the intermediate circuit via an optocoupler, where it is demodulated by a low pass and then transferred to the main controller as the analog signal IC. 7.3.5

The Main Controller and its Interfaces

The main controller board coordinates all processes inside the ME402. Its central component is a C167 microcontroller equipped with a number of peripheral functions. This assembly can be subdivided into the following functional blocks: •

controller core and graphics controller

•

I2C bus and its associated circuitry (periphery)

•

SPI bus

•

CAN bus, RS232 and footswitch (SIP/SOP) interfaces

•

one-wire bus (as from HW02)

This module is located on the main board, directly behind the front panel.

7.3.5.1 Controller Core and Graphics Controller The microcontroller used is a 16-bit system (C167) with integrated timer/counter functions and integrated A/D converter. Its configuration includes a non-multiplexed, 15-bit-wide address bus (LSB A0 not used) with four additional port signals as addresses A16 to A19, plus a 16-bitwide data bus. An I2C bus master, a CAN controller and a RS232 transceiver (UART) are integrated as well. Its immediate environment includes an external flash EEPROM as program memory, a static RAM and an external watchdog. In HW00 and HW01 units, the main controller board version I (C40-1926) has a program memory of only 1 MB; this has been increased to 2 MB in units with HW02 or higher hardware status. Upgrading the C40-1926 to 2 MB is basically possible, but requires returning either the board or the entire HF unit to the manufacturer. However, such memory extension is an absolute requirement for running SW2.368 or higher software versions. The controller allows you to reprogram the EEPROM via the serial interface. The boot program required for this task is executed in registers inside the controller. Therefore, software updates can be carried out very easily from outside – no need to open the unit. For HW00 and HW01 units, this involves setting the unit to boot mode via the Service menu. From HW02, this is no longer necessary, as the controller board version II (C40-2217) offers all the hardware features required. From HW02 – with controller board II (C40-2217), change status V02 or higher – the static RAM is buffered by a battery that also powers the internal clock. This allows administration and non-volatile storage of activation and error logs. For user functions, however, the battery is irrelevant. V 5.0

159

KLS Martin maxium® / maxium® Beamer Service Manual To reduce the workload for the main controller, a separate graphics controller has been integrated that manages the screen contents and generates all signals needed for LCD screen control. The generated image has a resolution of 640 x 480 color pixels; each color can be displayed with a resolution of 6 bits. However, this function is used only for representing gray shades, as the color impression is more or less independent from the viewing angle for the full colors red, green and blue, the mixed full colors yellow, magenta and cyan, and white and black. Units with hardware statuses HW00 to HW03 – with main controller boards I (C40-1926) and II (C40-2217) – have a graphics controller with integrated video RAM. Due to discontinuation of this component by the manufacturer, the main controller board III uses a graphics controller with external video RAM whose resolution of the colors red and blue is only 5 bits. However, this is of no significance for the specific application. A much more important difference between versions I and II on the one hand and version III on the other hand relates to the converter used for operating the fluorescent tubes (screen backlight) – this converter has been transferred from the controller board to the front board. In HW00 to HW03 units, the LCD screen is connected to the graphics controller via a 34-pole ribbon cable. From HW04, a 31-pole, flexible flat connector is used for this purpose. This cable supplies the screen not only with power, but with all the signals required for its operation as well.

7.3.5.2 I2C Bus and Associated Bus Users To enable control of a large number of peripheral indicators via LEDs – such as activation indicator, rotary switch backlight and NE status indicator – there is now a port expander available in the form of a serial synchronous data bus (I2C bus). These port expanders are connected to the main controller via a bidirectional data line and a clock line. This bus also serves for connecting additional peripheral functions to the main controller. A serial EEPROM is provided for the non-volatile storage of user-defined as well as basic settings. Besides, this bus is used for controlling the two external D/A converters that deliver the two analog signals TLS (for sound generator volume control) and PVW (for generating the comparison setpoint needed for HF output power overdose monitoring). An external calendar clock, buffered by a lithium battery, is connected to this bus as well. It allows checking the state of charge of the battery, thus enabling the microcontroller to check and display the battery status during the initial self-test.

However, an exhausted battery is of no consequence for the usability of the ME402 because the calendar clock, as well as the volatile parallel RAM, is intended only for service purposes such as saving error and activation logs. User-defined settings, in contrast, are stored in the non-volatile serial EEPROM, which needs no battery.

7.3.5.3 SPI Bus Communication with internal functional groups on the controller module, as well as with the external functional groups “monopolar patient controller” and “Argon Beamer”, is ensured by a serial interface consisting of three bus lines for data transfer from the main controller (MOSI), data transfer to the main controller (MISO) and clock synchronization (CLK), plus an address line for each bus user. Connection to the monopolar patient circuit controller is established via

162

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual optocouplers, while connection to the external Argon Beamer is made through a main board driver linked to the connecting socket for the Argon Beamer. The main controller board features two SPI bus users: The pulse pattern generator provides the signals used for controlling the HF generator; the sound generator generates the acoustic signals that indicate HF power activation, button operation (clicks) or alarm.

Two driving signals, GT1 and GT2, are required for driving the HF generator’s transistor bridge. These involve pulse patterns that are specific for each type of current. The patterns are generated by a programmable logic device (CPLD) but are set/provided by the main controller. In this process, the main controller charges the internal registers of this generator via the SPI bus. The internal signal GTEN enables the controller to switch the pulse pattern generator on and off. Similar to the HF generator’s driving signals, the sounds for the acoustic indication of HF activation and alarm statuses are also generated by a CPLD whose registers can be controlled by the main controller via a serial interface. While the acoustic generator has a frequency range of two octaves for four voices, only the first, the fourth and one of the two middle voices can be delivered to two separate outputs – which corresponds to a major or minor chord.

V 5.0

163

KLS Martin maxium® / maxium® Beamer Service Manual These voices can be switched on or off by the controller via the internal signal TEN, either individually or collectively. Irrespective of this, the first voice can be switched on by the external signal TON that is derived from the HF generator’s driver stage. This ensures that an acoustic signal is present also during unintended activation of the HF generator. A small audio amplifier drives the loudspeaker located on the unit’s rear panel. It allows volume adjustment across a range of 45 dB to 65dB through the analog direct-voltage signal TLS. The corresponding setting can be made on-screen via a submenu.

The main controller board III (C40-2327), implemented with HW04, involves a change in the internal address system for the SPI bus users, designed to increase the number of users that can be addressed. The software takes these differences into account by querying the hardware configuration. If an error occurs in this process and the hardware configuration is not identified correctly, this may lead to incorrect addressing of the SPI bus users, resulting in an error message such as “Patient circuit controller does not respond” or “CPLD xxx does not respond” or similar.

Besides, it can be used for transferring all user settings to another unit, e.g. to a temporary replacement unit in the event that the regular unit must be repaired. The large (dual-pedal) footswitch must be connected to the larger of the two footswitch sockets. The two pedal activation signals are received by optocouplers on the intermediate circuit side and then passed on to the controller as signals FCT1 and FCG1. In HW00 to HW03 units with main controller boards I (C40-1926) and II (C40-2327), the jumper X500 can be used to configure the input so that it can also be used for connecting an Erbe footswitch (for HF units of the ACC/ICC series) whose connector is basically identical to the KLS Martin plug but different in terms of pin assignment. In units with HW04 or higher – with a controller board III (C40-2327) – the jumper array X3 not only allows operation of the Erbe ICC footswitch, but also supports the large footswitch with three contacts (basic setting) and enables connection of a small footswitch with two pedals. Besides, a footswitch interface circuit can be connected as well, e.g. for telemetric footswitch activation with power supply from the socket. The small single-pedal footswitch must be connected to the smaller of the two footswitch sockets. It generates the controller input signal FCG2. However, this socket can also be used for connecting the small bipolar dual-pedal footswitch of the ME411 HF unit. In this case, the blue pedal corresponds to the black pedal of the single-pedal footswitch. In HW00 to HW03 units, the signal of the yellow pedal is supplied as FCT2 signal to the controller as well, but is currently not used by the software. From HW04, this signal is supplied to the jumper array X3, from where it can also be assigned to the FCT2 signal. To supply the line drivers of the serial interfaces and the optocouplers with voltage isolated from the intermediate circuit, the controller module features a small resonance converter that powers the interfaces via the T1 transformer.

One-Wire Bus

As from hardware version 02 and software version 1.336, the controller routinely checks the version statuses of the various boards. Therefore, from hardware version HW02 onwards, all boards feature a small memory with a one-wire bus interface, used for storing the respective ID data. This is necessary because the hardware version HW02 introduces new board versions with partially different properties. As these are used along with the boards already in use, the operating program must be capable of differentiating between the different types of board.

7.3.6.1 Display Screen The unit features a liquid-crystal color display (LCD) with an 8.4-inch (21-cm) screen diagonal that allows straightforward indication of all essential information – the currents assigned to each socket (including their parameters), the NE status, the menus and plaintext messages. Illumination is ensured by two fluorescent tubes installed at the upper and lower edges, respectively, which are powered by a converter – which is located on the controller module (up to HW03) or on the front board (from HW04) – and can be adjusted in brightness. Their average service life is approx. 20,000 hours, depending on the brightness level selected and ambient temperature. A low ambient temperature, in particular, tends to cause rapid tube ageing. When room temperature is low, the tubes may flicker after turning on the unit, but this effect usually subsides after a few minutes because the unit heats up during operation. The screen is supplied and driven by the controller module via a 34-pole flat (ribbon) cable. At the front, a solid glass window protects the display screen. The intermediate space between the pane and the screen surface is sealed to prevent ingress of foreign bodies.

These four button pairs are assigned to the four instrument connecting sockets. They are used to select either a cutting or a coagulation function (or current) for the respective output. The selected parameters are then displayed on the screen. A flexible cable is used to connect the membrane keypad to the front board, where the signal lines connect to a keyboard matrix. From there, the signals are transmitted to the main controller.

7.3.6.3 Rotary Switch with Backlighting The central input device is the rotary switch located to the right of the display screen. By rotating the button, the user can increase or decrease parameter values or cycle through the items of a selection menu. Pressing the button (“axial click”) completes and confirms the selection. The rotary switch is also connected to the front board, from where its signals are sent to the main controller. The pressure switch function is integrated into the keyboard matrix of the channel selector buttons. The rotary switch is surrounded by an illuminated ring that indicates its current functional assignment. If it lights yellow, the rotary switch can be used for setting a cutting parameter. Blue means availability for coagulation parameter setting, while a white ring allows navigation in the menu. A currently inactive, dark ring means that rotary switch operation would not trigger an action. In this case, it must first be activated by pressing a channel selector button or activating an HF current. The three light-emitting diodes (LEDs) that give the ring the appropriate color are located on a small board at the edge of the ring. This board is connected to the front board by cable, where the LEDs are connected to a driver circuit controlled by an I2C bus expander that is connected to the main controller via the I2C bus.

7.3.6.4 MENU Button To the right of the display, the unit features a membrane key with which the various menu levels can be accessed. This button is connected to the front board via a flexible cable, where it is integrated into the keyboard matrix in the same way as the channel selector buttons.

7.3.6.5 Activation Indicators Four light exits (light guides) next to the instrument connecting sockets indicate which of the HF outputs is currently activated. They light up yellow for cutting and blue for coagulating. The eight light-emitting diodes (LEDs) that illuminate the light guides are located on a small board connected to the front board by cable, where the LEDs are connected to a driving circuit controlled by an I2C bus expander that in turn is connected to the main controller via the I2C bus.

In standby mode, the red LED flashes with only half its normal brightness. The light intensity will increase as soon as the user activates monopolar HF current. The two light-emitting diodes (LEDs) that illuminate the light guide are located on a small board connected to the front board by cable, where the LEDs are connected to a driving circuit controlled by an I2C bus expander that is connected to the main controller via the I2C bus. From HW04, the board is equipped with a one-wire identifier which identifies the socket configuration for the system.

7.3.6.7 Socket Illumination To ensure that the electrode cable plugs can be easily and safely inserted into the sockets even in darkened rooms, the edges of the sockets are illuminated by a transparent plastic plate whose inner edge features a number of white LEDs. A plug-in connection links the board carrying these LEDs to the board carrying the LEDs for the activation indicators.

7.3.6.8 ON-OFF Button The key with which the ME402 can be turned on and off is a pushbutton connected to the front board. There, the two lines are looped through to the main controller only, then from the main controller board to the main board only, and from there to the power manager module.

The maxium® Argon Beamer MB402 is an accessory unit for use with the ME402 maxium® HF unit. It generates a defined gas flow in the range of 0.1 to 12 l/min. The gas flow is simultaneously activated with the HF current. As this Beamer is exclusively controlled through the ME402, all settings (gas flow rates, etc.) are made on the latter. The argon gas and the HF current eventually merge in the patient-side (distal) part of the applicator. To irrigate the applicator with argon gas prior to connection (in order to remove the air still present in it), a special button is available on the unit (the PURGE button/function). It allows the user to generate a pure gas flow without HF current activation. The coagulation process utilizes a special property of the inert or noble gas argon, namely its easy ionizability. By delivering the HF coagulation current to the tissue surface as part of (or “packed” in) a directed, ionized gas beam (argon beam), better – i.e. more targeted and more uniform – surface coagulation results can be achieved than in conventional spray coagulation. The cutting process, in contrast, uses the argon gas as a protective gas flowing around the cutting electrode. While the gas is neither actively involved in the current delivery nor in the cutting process, it counteracts the generation of combustion products. And in both applications, the gas beam helps to clear the surgical field by blowing aside any liquids present on the surface.

KLS Martin maxium® / maxium® Beamer Service Manual Argon gas is usually supplied in pressurized cylinders having a filling pressure of 20 MPa (200 bar). This high internal pressure is reduced to 250–450 kPa (2.5–4.5 bar) by means of the MABS pressure reducer mounted directly on the cylinder. At this reduced pressure, the gas is then delivered to the MB402 maxium® Beamer. Alternatively, the MB402 can be connected to a central argon gas supply system (if available), provided its operating pressure lies in the required range. For such connection, you need a special adapter hose available on request (special KLS Martin accessory). Through its controller, the MB402 automatically ensures that the actual gas flow available at the distal (patient-side) end of the applicator matches the set rate. Different applicator flow resistances are automatically taken into account and compensated – and therefore do not affect the gas flow rate. This makes the MB402 suitable also for endosurgical applications, where applicators with very thin flexible tubes are used. In the usual setup, the MB402 and the ME402 are placed on top of each other. This is a particularly convenient and ergonomic arrangement if the maxium® Cart is used (which has been specially designed for this purpose, offering ample storage space for the argon gas cylinder as well). Via a special connecting cable, the MB402 is both powered and controlled through the ME402.

Argon

The chemical element argon (atomic number 18) is an inert or noble gas present in the ambient air in a concentration of 0.93%. It is extracted from air by liquefaction. Due to its inertness, argon by itself does not undergo chemical reactions, which means that, while odorless, it is neither ignitable nor aggressive nor poisonous. This prevents the formation of argon-based disintegration products in the argon beam plasma. Moreover, its release into the ambient air (from which it has been extracted) poses no environmental problems at all. Although all noble gases can basically be used for beamer operation, the MB402 has been designed for operation with argon because this inert gas is not only by far the cheapest available, but the one most readily accessible as well. Gebrüder Martin recommends using “quality 4.8” argon characterized by a purity of more than 99.998%. Although such a high degree of purity is not really required for maxium® Beamer operation, only such high-purity gases – which are primarily used in chemical analytical procedures – can be obtained in cylinders that are not part of the usual production and distribution cycle (which includes cylinders used in the manufacturing and craft sectors, which may be heavily contaminated). While it is possible to use argon gas of a quality level higher than 4.8, this would not bring any additional application advantages. Due to its inertness, and unlike carbon dioxide (also used for medical-technical purposes), argon gas has no adverse influence on the lung’s gas exchange processes. Nonetheless, if present in very high concentrations, argon can displace the air needed for breathing. No such concentration can occur, however, if the room is ventilated in a normal way and the MB402 is used as intended, thus ruling out suffocation under normal operating conditions. But one should bear in mind that argon does constitute a potential danger if it escapes in poorly ventilated places or is released in pits or cavities. Since argon is heavier than air, it can accumulate on the floor if ventilation is insufficient.

Microcontroller

The MB402 Argon Beamer is capable of generating a defined argon flow in the range of 0.1 to 12 liters per minute at the patient-side (distal) output of the applicator. The pneumatic unit required for this has been combined in a monolithic valve block located on the main board. In the MABS pressure reducer that is directly mounted on the cylinder’s angle valve, the argon gas, which is usually delivered in cylinders with an internal pressure of up to 200 bar, expands to an intermediate pressure (output pressure) of 2.5 to 4 bar. At this pressure, the gas is then supplied to the MB402 via a hose connected to a quick-action coupling (as used with compressed-air-operated tools) located on the unit’s rear panel. Inside the Beamer, a hose (or flexible tube) delivers the gas to the valve block, which features a filter at its input side to prevent ingress of foreign bodies. Immediately behind the filter, the unit has a connector for the pressure sensor S1, which is located on the board outside the valve block. S1 has the task of measuring the input pressure to provide the system with information on whether the pressure is inside the permitted range or not. Besides, it provides information on the cylinder’s current filling level. Valve V1 behind the input has the function of a shutoff valve that opens only upon activation of the MB402, provided the input pressure is in the permitted range. This valve is followed by the control valve V2 used for setting the gas flow rate. V2 is driven by a variable current supplied by a switching amplifier. The actual flow rate is measured by the pressure difference created when the flow passes through a narrowing in its path. This value is picked up by the differential-pressure sensor S2 located outside of the valve block. The pressure signal increases quadratically (i.e. by square law) relative to the flow, which means – given the flow range of 0.1 l/min to 12 l/min – a maximum ratio of 120 between the two flow values, which in turn would translate into a maximum ratio of 14,400 between the pressure values measured. As this would make excessive demands on the properties of the measuring amplifiers used, the cross section of the 172

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual aperture/orifice is increased as soon as a flow rate of 1 l/min is exceeded. This is done by opening a bypass with a larger cross section via valve V3. As a result, the entire control range is subdivided into two separate ranges characterized by roughly identical setting ratios of 10. In addition, the relay K1 allows switching the amplification of the signal amplifier mid-way through each setting range for optimized control of the microcontroller’s analog input. During the initial self-test, the flow control is checked as well. This requires gas flow activation at a very low rate, but this flow cannot be directed towards the applicator. Therefore, valve V4 opens a path that releases this gas flow inside the unit. V4 is opened also during the recalibration cycles run in standby mode. Behind the gas outlet, the unit features another valve (V5) that is closed in standby mode but releases/opens the output upon activation of the MB402. This prevents a return flow through the applicator in the event of back-pressure (as can be the case in endoscopic interventions when using insufflation). This valve is preceded by the pressure sensor S3 that measures the output pressure. This accounts for (i.e. compensates) the flow resistance of the applicator. A high flow resistance causes overpressure in the valve block, relative to the atmospheric pressure. If the gas flow were regulated to meet the setpoint at the valve block output, this would actually mean a higher flow rate at the applicator’s distal end than the rate set, due to the fact that the gas expands while passing through the applicator. By measuring the excess pressure, the control system therefore takes account of this effect, with the result that the flow rate available at the distal end of the applicator exactly matches the set flow rate. The pressure sensors are piezoresistive sensors, with a measuring transducer that consists of a semiconducting diaphragm into which four identical resistors have been diffused and interconnected into a resistance bridge. When charging the diaphragm with pressure, the values of these resistors change as a result of diaphragm deformation, which translates into an output voltage differential. Unavoidably, a non-negligible output offset voltage characterizes such sensors. In the case of the MB402, these offset voltages of the sensors S2 and S3 are picked up and automatically compensated during the initial self-test after starting the unit. Such compensation is subsequently checked by recalibration at intervals of approx. 5 minutes in order to capture offset temperature drift as well. Gas flow control is performed by a microcontroller that also controls all other functions of the unit and monitors operation, displaying error messages if malfunction occurs or blocking gas flow activation if need be. Moreover, the controller periodically activates a charge pump that in turn actuates the relay K1. In the event of controller failure, the charge pump is no longer operated and K1 drops out, thereby de-energizing and therefore closing all valves.

Measuring the Filling Level of the Gas Cylinder

The status indicators on the ME402’s display include an optional indicator that keeps the user informed about the argon supply (or filling level) of the pressurized cylinder connected to the MB402. Because, unlike carbon dioxide for example, argon does not liquefy under high pressure but remains a compressed gas inside the cylinder, its pressure is a direct measure of the filling level. The column shown on the ME402’s screen, which represents the cylinder’s filling level, is consequently not in line with the physical facts. However, it is much easier to represent the process of continuous draining simply by means of a column than by trying to give a graphical description of the gas expansion process (that actually takes place in the cylinder). Therefore, the filling level can be indicated by the cylinder’s internal pressure, as evidenced by the manometer provided on the pressure reducer. The manometer indicates the gas pressure inside the cylinder when the angle valve has been opened. The maximum filling pressure of 200 bar corresponds to a full cylinder.

As the pressure reducer with the manometer is usually located either behind the units or inside the trolley (Cart), checking the pressure level in this way is possible only by looking behind the systems or opening the Cart’s door. However, the filling level can also be determined indirectly, using the pressure present at the Argon Beamer’s inlet. This method takes advantage of a specific property of pressure reducers – namely that the pressure reducer’s output pressure is not a constant quantity but, rather, depends on the input pressure too. A brief description of the functional principle of pressure reducers may help to understand this:

A valve that controls the gas flow is located between the high-pressure input and the lowpressure output of the pressure reducer. The disc of this valve is driven by a diaphragm that in turn is pressed upwards with a force FF by a spring located underneath the diaphragm, thus opening the valve. On the upside, however, the force FN acts upon the diaphragm due to output pressure. As gas flows through the valve gap from the high-pressure side, output pressure builds up to a point at which the force FN (exerted by output pressure) is exactly equal to the force FF exerted by the spring. If the output pressure subsequently continues to rise, the diaphragm moves downwards, thus closing the valve with the result that no gas can flow in any longer. As gas flows off at the output pressure side, the spring will again open the valve enough so gas can flow in again from the high-pressure side to restore the balance between the forces acting on the diaphragm. In this way, output pressure is automatically regulated. However, there is still another, third factor involved in this system: the force FH, which is the product of the high pressure and the effective valve surface, and which supports the force FN. Therefore, the question of what amount of output pressure is required to achieve a balance

174

V 5.0


Output Pressure in bar

between the forces acting on the diaphragm also depends on the high pressure. If the cylinder’s internal pressure is very high, this balance is achieved with a comparatively low output pressure – and vice versa. This means that output pressure increases while the cylinder is being drained, as can be seen from the pressure reducer’s output characteristic. Consequently, the cylinder’s filling level can be determined by measuring the output pressure. 4

Nonetheless, this method is subject to certain limitations and peculiarities that require some explanations: 1. This type of pressure measuring works only when the MB402 is in standby mode (as long as no argon gas flow is activated). As soon as argon flows to the MB402 through the pressure reducer and the hose, a pressure drop occurs, depending on the selected flow rate. This leads to a different pressure at the MB402’s gas inlet that cannot be used any longer for determining the cylinder’s filling level. Therefore, the filling level indicator is “frozen” during gas flow activation – which constitutes no problem, though, because there is no noticeable change in the filling level during activation. This can cause irritation, however, if the user forgot to open the angle valve, in which case only the gas contained in the pressure reducer will expand while the pressure on the pressure reducer’s input side rapidly decreases. As a result, the filling-level indicator will drop heavily (or even trigger the alarm) upon deactivating the gas flow – even though gas was indicated to be in sufficient supply prior to activation.

KLS Martin maxium® / maxium® Beamer Service Manual 2. The pressure reducer valve does not close by itself (force-free). Rather, a closing force is required for closing it tightly. Such force is created by the slowly increasing output pressure. At the end of an activation phase, when the argon flow through the pressure reducer stops, the valve disc is initially lightly pressed against the gasket. Due to untightness, however, a small amount of gas continues to flow through the valve, causing the output pressure to increase slowly until the closing pressure is high enough to close the valve tightly. This effect actually differs from one pressure reducer to another and can also be influenced by environmental operating conditions. Usually, such output-pressure “lagging” takes only a few seconds. The MB402 automatically takes this effect into account by starting pressure measurement only a few seconds after gas flow activation has been stopped. However, if such “lagging” takes longer, this will cause the filling-level indicator column to jump upwards, then returning slowly to its original (final) level. 3. If the pressure reducer is not charged with high pressure, the valve is pressed fully open by the spring and the elastomeric gasket of the valve seat expands. Once the pressure reducer has been charged with pressure, with the valve working as a gas flow regulator, the elastomeric gasket is mechanically loaded as well, which slightly changes its shape (creep). This means that the output pressure will continue to change slightly after the high pressure begins to act on the valve, reaching its stationary value only after a few minutes. This must be taken into account when calibrating the unit’s pressure measuring system (“teach-in”). 4. As the shape of the output pressure curve is slightly different for different MABS pressure reducers, it may be necessary to adjust the MB402. Through the so-called “teach-in” procedure, it is possible to record the parameters of the connected pressure reducer and store them in the non-volatile memory. Such adjustment has already been made at the factory for the pressure reducer supplied with the MB402, so there is usually no need to repeat the process during installation of the unit and initial user instruction. However, if the user has doubts about the accuracy of the filling levels indicated on the screen (e.g. after exchanging the pressure reducer or the MB402), check and adjust the filling-level indicator following the instructions provided in section 4.1.2.

Besides, check the internal path of the NE line from the socket to the main board and from there to the monopolar board. Particularly if the error message 35 appears alternatingly with error message 50, it is very likely that the fault is located in the NE monitor of the monopolar board itself. 41. Conflicting activation actions – HF output interrupted! Application error. The unit recognizes two simultaneous activation signals from the same activation source. This prevents an unambiguous decision as to which type of current should be activated. 48. This channel must be selected first: no activation! The user attempted to activate a channel for which no current has been selected. 49. Single-plate NE not allowed by setup, therefore NE error! The unit recognizes connection of a single-plate (non-split) NE, although such NEs have been excluded in the “Setup” menu. 50. NE error: NE cannot be evaluated! Short circuit? System or electrode error. The signal of the NE monitor is out of the specified range, which is possible only if the monitoring circuit is purely capacitive (due to contact between the two halves of a split NE) or monitor failure occurred. As a result, monopolar HF current activation is blocked. 51. Pin error on monopolar channel M1: Please correct! Application error. The single-pin 4-mm plug of a monopolar instrument connecting cable has been inserted into the wrong socket contact belonging to the finger-switch control of a 3-pin plug (see Operating Instructions). As a result, the HF current flows through the finger-switch control circuit when activated with the footswitch. To prevent damage to this control circuit, the HF current is cut off as soon as it exceeds a certain limit and the above message is displayed. 52. Pin error on monopolar channel M2: Please correct! Same as 51, but for the M2 monopolar output. 54. Attention: Instrument makes tissue contact. Activation locked! During the initial self-test of the bipolar impedance monitors, the unit expects output signals corresponding to open output circuits. If this is not the case, this message is displayed. If a bipolar instrument connected to the unit already makes tissue contact, this instrument must be briefly disconnected from the unit to enable completion of the self-test. If the message persists even after switching the unit off and on again, one of the two impedance monitors inside the unit is defective. V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual 56. Int. error 56: Dosing error. Intermediate circuit relay released! The overdosage monitoring circuit detected an excessively high HF output power (exceeding the tolerance limit of the power value displayed). If this message is displayed generally or frequently (i.e. for many power settings), this indicates an internal fault. If the excessive power can be measured with an HF power meter, it is likely that the fault is in the power manager board. If little or no power is available, the fault is in the main board. If this error message is displayed only at partial load when performing safety checks on some monopolar contact coagulation currents, check whether this is possibly caused by a coiled-up cable. If a long cable (e.g. the 5-m cable of a monopolar handle) is used for power measurement, be sure to uncoil it first (no loops!). 57. Int. error 57: Power monitoring I1<>I2! System fault. The two measuring points at which the same internal current is monitored provided significantly deviating signals I1 and I2 although the measured values should be identical. In this case, the fault is located either in the signal electronics of the power manager board or in the measuring transducers on the main board. 72. Internal communication error! System fault. Malfunction in main controller communication via SPI bus. If this error message is displayed after switching on the unit, the cause could be a problem in reading out the hardware identifiers. Turn unit off and restart it. 75. Overtemperature: Power output interrupted! The temperature limit of 120°C has been exceeded at one of the heat sinks of the HF generator’s semiconductors. To protect the semiconductors from overheating, HF output is blocked until the temperature has dropped to 80°C. 76. Self-test: Activation attempt during system start! Warning notice. During the self-test routine, the unit registered an activation signal from one of the control sources. Activation will not be carried out, not even after completion of the selftest. Activation will be possible only after the signal has turned passive (and is then activated again). 78. 79. 80. 81. 82.

KLS Martin maxium® / maxium® Beamer Service Manual 87. Internal scaling error 87: I1 power measurement overflow! System fault. The internal signal I1, which represents the actual power, is out of range. The fault is located in the power manager board or the controller board, or possibly also in the current transformer for I1 on the main board. 89. Internal error 89: WDC oscillator out of range! System fault. The frequency of the WDC rectangular signal is also used as a reference for monitoring the main controller’s clock frequency. In case of mismatch, there has been a change either in the clock frequency (controller board fault) or the WDC frequency (fault on power manager board). This fault can also occur as a result of brief mains voltage interruptions. Can be cleared in this case by switching unit off and restarting it. 91. NE communication with monopolar sub-controller! System fault. SPI bus communication between the main controller and the patient circuit controller is interrupted. This error may also be displayed alternatingly with errors 92 and 140. If the fault does not disappear by itself, it may be located in the controller board, the bipolar board or the monopolar board. However, it could also be caused by a defective optocoupler. Before replacing the monopolar board, check that power supply to the NE-related parts of the circuit is OK on this board. 92. Activation communication with monop. sub-controller! System fault, same as 91. 93. Self-test: Disconnect bipolar instrument at B1! An impedance signal has been registered during the initial self-test for the bipolar impedance monitor 1. If the error message was definitely not caused by a connected instrument or test cable, then the bipolar board must be defective. 94. Error 94: Mono-subcontroller firmware version conflict! This message can be displayed after updating the software. In this case, the monopolar board still operates with an old software version lacking boot-loading capability. In such case, the board must be programmed separately. To replace the board, contact the Martin Service Center. 95. Error 95: Unable to restore user programs from EEPROM! 96.

This may be due to failure of a peripheral component of the microcontroller. If it is not possible to clear the error by turning off and restarting the unit, the main controller board is defective. If the error is displayed after updating the software, repeat the update procedure. 101. Argon Beamer warning: Low dosage 102. Argon Beamer warning: Argon input pressure too low 103.

Module Status Lamps and Their Functions

The boards feature a number of indicator lights (LEDs) representing specific signals or indicating the presence of voltage. They can be used for recognizing faults. 9.2.1

Main Board

From HW02, the main board has a red LED B1 that indicates whether voltage is present at the output of the PFC stage of the electrolytic capacitor C8. In units up to HW05, this LED is always on under normal conditions if the unit has been connected to the mains. From HW06, it lights up only after the unit has been turned on. If this LED does not light even though mains connection has been established, then either the mains input circuit or the B1 circuit itself is defective. Frequently, the line fuse (located in mains connector socket) has been blown in this case, but this is only a secondary fault caused by a PSU short. 9.2.2

Controller Board

Up to HW0q1, the controller board features a red heartbeat LED; from HW02, this LED is green. Under normal conditions, it flashes continuously at a frequency of 1 Hz to indicate correct execution of the operating program of the main controller. Certain error/fault conditions are indicated by changes in the flashing regime (periodic flash sequences followed by pauses) as follows: 1 pulse:

non-used

2 pulses:

RAM test error; cannot be consistently written with “0”

3 pulses:

RAM test error; cannot be written with bit pattern

4 pulses:

Trap B interrupt

5 pulses:

Device ID of graphics controller cannot be read.

All of these error messages indicate a fault in the core of the controller. If reprogramming (i.e. updating the software) does not help, the controller board must be replaced. The controller board versions I and II (C40-1926, C40-2217) of units with hardware status HW00 to HW03 additionally feature a red LED that lights up continuously but has no indicating function. Controller board III (C40-2327), used in units with hardware status HW04 or higher, has a red LED that is off in normal operation. If it lights up, this means that the protective circuit of the converter powering the serial interfaces and the footswitches has been tripped due to overload. The serial interfaces and the footswitches function no longer in this case. If the overload has not been caused by connecting a plug with incompatible pin assignment to a serial interface, then one of the interfaces is defective and the controller board must be replaced. 9.2.3

Power Manager Board

The LEDs located on the power manager board indicate the following operating and error conditions: VH: Green LED hidden behind the protective cover in the upper left section of the board. It lights up continuously in normal operation to indicate presence of the line-side auxiliary supply voltage generated by the step-up converter. If the auxiliary supply voltage (VH) is missing

WDC: Green LED hidden behind the protective cover, indicating that the prestabilized output voltage provided by the step-up converter is present within the normal tolerance range. This LED does not light up continuously; in fact, it is switched on and off periodically at a frequency of 130 Hz. As the human eye cannot perceive such rapid changes, however, the LED seems to light up continuously with medium brightness. If it remains dark or is unusually bright, this V 5.0

195

KLS Martin maxium® / maxium® Beamer Service Manual indicates that the stabilized DC+ direct voltage is outside of the tolerance range or the detection circuit itself is defective. In normal operation, DC+ has a value of 390 V. If the tolerance range is exceeded, the “WDC” LED remains dark; if the voltage drops below the threshold, it lights up brighter than usual. This is caused by a fault either in the corresponding regulator on the power manager board or in the actual-value sensor on the main board. 15V: Green LED that indicates presence of the auxiliary supply voltage of +15 V. The control system of the ME402 cannot work without this auxiliary voltage. If this voltage is not available, this can be due to a fault in the auxiliary PSU located on the main board (check fuse F1), or to failure of the corresponding voltage regulator on the power manager board, or to a short somewhere in the 15V supply circuit. 5V: Green LED indicating presence of the auxiliary supply voltage of +5V. This voltage is derived from the +15V voltage. If it is not available even though the +15V is present, no sound is available and some bipolar board functions will be missing. This can cause error messages concerning some bipolar board functions to be displayed, even though the fault is not located on the bipolar board. A missing +5V voltage can be caused by a short in the +5V circuit or by a defect in the voltage regulator on the power manager board.

Monopolar Board

The monopolar board has two interfaces for finger switch signal transmission to the HF output sockets M1 and M2, plus a section that is connected to the NE and also contains the microcontroller of the monopolar patient circuit. The following signals are indicated by monopolar board LEDs: CT1: Yellow LED that lights up if the yellow finger switch (for cutting) is operated on an electrode handle connected to M1. CG1: Green LED that lights up if the blue finger switch (for coagulation) is operated on an electrode handle connected to M1. PIN1: Red LED. If it comes on after monopolar HF current has been activated, this indicates that HF current passes through the finger switch interface connected to M1 because the 4mm connector of an instrument cable has been wrongly plugged into one of the control contacts instead of inserting it in the left part of the HF socket. During high-voltage coagulation, this LED may also come on as a result of “crosstalk” (feedover) in the handle cable when using finger switch activation. In this case, however, it does not signal a fault. If no HF current has been activated and this LED comes on, it indicates that both finger switches have been operated. CT2: Yellow LED that lights up if the yellow finger switch (for cutting) is operated on an electrode handle connected to M2. CG2: Green LED that lights up if the blue finger switch (for coagulation) is operated on an electrode handle connected to M2. PIN2: Red LED. If it comes on after monopolar HF current has been activated, this indicates that HF current passes through the finger switch interface connected to M2 because the 4mm connector of an instrument cable has been wrongly plugged into one of the control contacts instead of inserting it in the left part of the HF socket. During high-voltage coagulation, this LED may also come on as a result of “crosstalk” (feedover) in the handle cable when using finger switch activation. In this case, however, it does not signal a fault. If no HF current has been activated and this LED comes on, it indicates that both finger switches have been operated.

REG: From HW00 to HW02, the monopolar boards I and II feature this yellow LED. It indicates that the board’s DC regulator is active. Along with the REG LED, the FR LED located on the power manager board lights up as well. By setting the jumper to its alternative position on plug connector X6, it is possible to bypass the regulator, which causes the REG LED to light up continuously. This procedure is used to adjust the operating point (transfer characteristic) of the optical link with trimmer DCM on the power manager board in units with hardware versions HW00 to HW02. If you forget to move the jumper back to its original position on X6 after the adjustment has been made, the power controller will be blocked as a result. An error message (error 190: “VDC self-test failed”) will then be displayed during the initial self-test. DCR: From HW03, the monopolar board (version III or higher) features this yellow LED that lights up brightly to indicate that the DC regulator on the monopolar board is active. Along

KLS Martin maxium® / maxium® Beamer Service Manual with the DCR LED, the FR LED located on the power manager board lights up as well. If the DC regulator is not active, the DCR LED glows only faintly. However, it is never fully dark. ACR: From HW03, the monopolar board (version III or higher) features this red LED that lights up brightly to indicate that the AC regulator for the HF output voltage on the monopolar board is active. Along with the ACR LED, the FR LED located on the power manager board lights up as well. If the AC regulator is not active, the ACR LED glows only faintly. However, it is never fully dark. DCR and ACR can only light up in normal operation if monopolar HF current has been activated. If one of these two LEDs lights up brightly, even though no current has been activated, this indicates a fault on the monopolar board. In this case, it is not possible to generate HF output power, as the power controller is blocked and an error message is displayed during the initial self-test. A possible explanation is that the Care Cut or Care Coag current is still set to setpoint “0”. In this case, the setting must be changed to deblock the power controller. HBT: Green LED that flashes at a frequency of 1 Hz to indicate that an operating program is being executed in the monopolar board microcontroller. If this LED is not flashing while other LEDs are on, either the operating program stored in the program memory is incompatible (due to update failure), or there is a hardware defect on the monopolar board. ACTI: Yellow LED that lights up if HF current has been activated. It also comes on when activating bipolar current. COM: Red LED signaling interruption of the SPI bus communication between the main controller and the monopolar board controller. As the self-test of the monopolar board controller is very much shorter than that of the main controller, this LED lights up with interruptions (when communication with the controller in the monopolar applied part is checked during the selftest) until the main controller’s self-test is completed. If it is still on although the LED HBT is flashing, this signals an SPI bus communication problem caused by interruption of an SPI bus signal on the monopolar board, the bipolar board, the controller board or the main board, with the latter being the most likely candidate (optocouplers U1 to U4). If communication is resumed after an interruption, the LED goes out again. FAIL: Red LED signaling that the microcontroller in the monopolar applied part detected a fault during the self-test. Die FAIL LED remains on even after the error or fault has been cleared. It goes out only after a new initial self-test has been carried out following reset. CRB: Green LED signaling (in HW03 or higher) that the power controller has been blocked via the optical link. If CRB is on, the FR LED on the power manager board is on as well and no HF power can be emitted.

Bipolar Board

Up to HW05, the bipolar board has two sections in which signals are indicated via LEDs; from HW06 onwards, there are three sections of this kind. The first of them is the interface for the finger switch signals; the second section refers to the impedance monitors; and from HW06, the bipolar board III has a dedicated microcontroller that also uses LEDs to indicate operating states. Whereas only finger switch signals are indicated on the bipolar board I (HW00 and HW01), the bipolar board II (from HW02) and the bipolar module III (from HW06) provide indicators for the operating states of the two impedance monitors as well.

Faults in the Power Supply System of the ME402

Unit cannot be turned on: The ME402 shows no response after pressing the ON-OFF button (power switch); both the screen and the indicators remain dark. Provided a fault in the power cord or the building installation can be ruled out, you should first check the fuses located in the power supply socket. If both fuses have been blown and are black inside, a short in the mains input circuit is likely. In fact, it is highly probable that the transistor of the step-up converter has been shorted. In this case, the main board must be taken out and either repaired or replaced. If the unit is still inoperable after replacing the main board and the fuses, the power manager board is defective as well. If both device fuses are OK or only one has been blown without being blackened inside, the fault has likely been caused by a mains input circuit overload (due to a fault in the power electronics system powered by the mains input circuit) or by a fault in the signal section of the power manager board. To check this, replace the blown fuse (if applicable) and try to restart the unit. Attention! Never remove or insert the power manager board as long as the unit is connected to the mains because this could destroy the semiconductors of the mains circuit! If, with the power cord connected, the green VH LED lights up after pressing the ON-OFF button, this means that the PFC stage is working. Together with VH, the WDC LED will light up as well in this case. A voltmeter connected between the measuring point “DC-” and the left side of fuse F1 or F2 must then indicate a direct voltage DC+ of 390 V. If the two LEDs VH and WDC are off (dark) and no voltage can be measured at F1/F2, then the mains input circuit is interrupted, with the fault located either in the power supply socket, the main board or the connecting cable between these two components. If the two LEDs are off and only a voltage in the range of the mains voltage peak (approx. 325 V in a 230-V supply network, approx. 165 V in a 115-V supply system) can be measured at F1/F2, then the input controller either does not work or cannot be switched on. This can be checked with the S1 switch located on the power manager board, which is connected in parallel to the ON-OFF switch located on the front panel. If the unit can be turned on with this switch, then the path of the ON-OFF switch is interrupted or the switch itself is defective. This path leads from the power manager board to the main board to the controller board, and from there – via the connecting cable – to the front board (to which the switch is connected). However, if operating S1 generates no response, this may mean that the fault is in the power manager board. If replacing the power manager board does not help, the fault must be on the main board. If the VH LED is on but the WDC LED is off, this indicates a fault in the input controller’s control circuit. In this case, the voltage measured across DC- and F1/F2 significantly deviates from 390 V. This indicates a fault in the power manager board.

V 5.0

203

KLS Martin maxium® / maxium® Beamer Service Manual If both LEDs, VH and WDC, are on or light up intermittently while the green LEDs +15V and +5V remain dark, then the 15-V auxiliary supply voltage of the intermediate circuit either broke down or has been shorted. First check the F1 fuse protecting the auxiliary voltage supply. If blown, replace the fuse (M0.125A, i.e. 125-mA, medium time-lag). Caution! The fuse is located in the primary part of the power supply section, carrying voltage to ground even in switched-off condition as long as the unit is connected to the mains! If, upon starting the unit, the +15V LED lights up either briefly or continuously, this indicates a short in one of the switching circuits powered by +15V. Therefore, you need to locate the faulty circuit. Chances are that the short is located either on the power manager board itself or on the controller board. In such an event, the rectifier diodes on the power manager board (which are located next to the version number) can get unsoldered and displaced, resulting in a short. However, the short as such is only a sequential or secondary fault. If the +15V LED remains dark and F1 is blown immediately again, this indicates a short in the primary section of the auxiliary voltage supply circuit and the main board needs to be replaced in this case. Frequently, however, such a short is merely a sequential fault caused by overload due to overload on the secondary side. If the +15V LED is on but the unit shows no visible response, then the fault is in the controller board. If the +15V LED is on but the +5V LED remains dark, this indicates a fault in the 5-V auxiliary voltage supply, either in its generation or due to a short. Although screen contents are available in this case, the unit cannot be activated because important functional groups are not powered. If, especially after performing repairs or safety checks, the unit can no longer be switched off, you probably forgot to set the jumper X10 back to its “2-3” basic position on the power manager board. The “1-2” position is used to ensure that the unit comes on again after power interruption during automated safety tests (which would not be the case otherwise).

9.4

Faults in the HF Generator and the Energy Flow Path of the ME402

If the ME402 can be operated normally but only little or no HF output power is available at the four outputs without any error message being displayed, this indicates a fault in the power controller or the HF generator or the drive circuit. In standby mode, the three LEDs FR, PR and UR are off (dark). As soon as the unit is activated without load, the UR LED lights up to indicate that the voltage regulator is active. When activating cutting current at nominal load, the green LED PR comes on to indicate that the power controller is active. When selecting Pure Cut 400 and activating the cutting current at no-load, a direct voltage of 140 V can be measured across the measuring points VDC (X15) and GND (X16) on the main board, with UR lit. If, upon activation, only very little or no direct voltage is present at the VDC measuring point, this can have several reasons: no direct voltage generated, or a short occurred, or the overdosage monitoring circuit interrupted the current path between the power controller and the HF generator. It may also be that HF output was blocked by a monitoring (e.g. NE alarm) function in the normal course of operation. This must be checked as well. 204

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual If the yellow FR LED is on even in non-activated state, you forgot to reset the X6 jumper to its original position on the monopolar board following calibration of the optical link for the arc regulator’s deviation (or control error) signal. If FR is on although X6 is in the correct position, this indicates a fault either on the monopolar board or on the power manager board. If FR goes out upon interrupting the optical link (i.e. disconnecting the fiber at one end), the fault is on the monopolar board. If, upon activation, the green PR LED comes on although no external load is connected to the output, this indicates a short either in the HF generator or in the rectifier of the power controller. As the nominal (output) power is then wasted inside the defective stage, the latter heats up strongly and can thus be easily located. In this case, the main board must be replaced. If the overdosage protective circuit responds, this releases the relay K1 on the main board. As a result, the REL LED lights up on the power manager board upon activation. If the relay dropout is a little delayed after activation, the monitoring circuit interprets this as caused by excessive output power. If the relay is no longer switched off after disconnecting the load from the HF output, you should check the power controller’s basic setting for correctness (for procedure, see section 9.1). If the relay is still switched off or the setting turns out to be correct, then there is probably a fault on the power manager board or – less likely – on the main board or the controller board. If the relay dropped out even prior to activation, then you should measure the voltage present between the DC- measuring point on the power manager board and the left ends of the main-board fuses F1/F2. If the measured direct voltage deviates from 390 V by more than 10%, the fault is in the input controller’s control circuit, very likely to be found on the power manager board. If, upon activation, a voltage can be measured across the measuring points VDC and GND on the main board but no HF power is available at the output, this indicates a fault either in the drive circuit of the generator bridge or the drive circuit of the output relays. The latter is likely if only one output or only one type of adjustment (high-impedance current or low-impedance current) is affected. The driving signals for the generator bridge are accessible at the two measuring points GT1 and GT2 on the main board. The measured value must be approx. 7 V at both terminals when activating Pure Cut current. If the signal is missing at one or both of these measuring points, this indicates a fault on the controller board. If only one of the two (monopolar or bipolar) channels is non-functioning, the fault is located either on the monopolar or bipolar board or on the controller board. And if only one type of adjustment is working, the fault is on the main board or the controller board.

9.5

Activation Path Faults

If the HF current cannot be activated through one of the activation paths while all of the other paths are functioning correctly, a basic fault in the HF generator can be ruled out. As a general rule, an HF activation path is in proper working order if the associated activation signal can be heard. If an HF output cannot be activated via the footswitch assigned (provided a fault in the footswitch itself can be ruled out), it is very likely that the fault is located in the SIP/SOP interface on the controller board. In such a case, the ME402 cannot be activated through either one of the two footswitch sockets.

V 5.0

205

KLS Martin maxium® / maxium® Beamer Service Manual If only coagulation current (blue pedal) but no cutting current (yellow pedal) can be activated, check whether the X500 jumper on the controller board is set correctly or whether an Erbe footswitch intended for ACC or ICC units has possibly been connected. While KLS Martin and Erbe ICC footswitches have the same type of connector, the pin assignment is different. You can adjust the ME402 to one or the other of these footswitches by simply resetting the X500 jumper on the controller board I or II. For controller boards III, the jumpers on plug connector X3 must be set as appropriate. If one or both monopolar HF outputs (M1 and M2) cannot be activated manually, you should check the finger-switch interface circuits on the monopolar board. Upon operating the yellow pushbutton on a handle connected to the M1 or M2 monopolar HF output, the yellow CUT1 LED for M1 or CUT2 for M2 must light up on the monopolar board (this can be more easily checked from the rear because the board’s upper side is hidden). Similarly, the green COG1 LED for M1 or COG2 for M2 must light up on upon activation of the blue handle pushbutton. If one of these LEDs remains dark or lights up only faintly, this probably indicates a fault in the monopolar board or the socket board. However, it can also be that the cable connection (individual conductor loop) between the main-board transformer T12 and the monopolar board is not OK. In addition to the above-mentioned LEDs for cutting and coagulation current activation, each of the two finger switch control circuits on the monopolar board features a red LED – PIN1 or PIN2, respectively – which indicates wrong current flow through the finger switch control if the instrument cable has been incorrectly plugged into the HF output socket M1 or M2. These LEDs may also light up faintly or fully when activating a finger switch (no fault condition). However, a fault is indicated if they light up during current activation via the footswitch. If automatic current activation by tissue contact is not possible, you need to check the impedance monitors (located on the bipolar board) for proper functioning. To do this, connect a voltmeter to the measuring points GND and IMP1 or IMP2, respectively (in the case of bipolar board I, these are separate measuring points; in the case of bipolar board II, the voltage is present at pins 9 and 10 of plug connector X24, to be measured with a bipolar measuring adapter). With the HF circuit open, the measured voltage must be approx. 5 V (bipolar board I) or 4.5 V (bipolar board II), provided an auto-coag current has been selected for the output. When shorting the circuit, the measured value must be below 0.5 V. If it is significantly higher, the cause may be incorrect adjustment. However, if the short-circuit value cannot be set as described in section 10.4, or if the signal does not respond to external shorting at all, the fault is in the bipolar board. If the impedance monitor works normally but activation is still impossible after shorting the circuit, then the fault is either in the signal transmission line between the bipolar board and the controller board or in the signal processing section of the controller board.

Settings and Checks & Tests

As all spare part modules have been pretested and adjusted at the factory, the correct basic setting is guaranteed when replacing an electronics module, so no special adjustment is necessary. Nonetheless, certain safety checks and tests are mandatory after any repair to verify correct reassembly of the unit.

10.1

Adjusting Positions of the ME402

All ME402 adjustments are made via adjustable resistors (trimmers) or via switches. Adjustment is necessary for the following functions: •

Setting the setpoints for the output power regulator and the regulator for the powercontroller output voltage, both located on the power manager board.

•

Setting the operating point of the fiber-optic (optical) receiver on the power manager board.

•

Setting the operating point of the HF output voltage regulator on the monopolar board (from HW04).

•

Setting the operating point of the NE monitor on the monopolar board.

•

Setting the operating frequencies and output signals of the two impedance monitors on the bipolar board.

•

Basic setting of the bipolar instrument recognition function on the bipolar board.

10.2

Setting the Power Manager Board

Upon replacing the main board, the power manager board or the controller board, it is necessary to check the basic setting of the two regulators for generator operating voltage and power limitation, as well as the setting of the monopolar optical receiver (and from HW06, the setting of the bipolar optical receiver as well). If a fiber-optic transmission link (optical link) to the power manager board has been interrupted, it is always necessary to check the basic setting of the optical receiver for correctness. The following tools and working aids are needed for these tasks: •

HF power meter (e.g. KLS Martin EPM3). This instrument should at least allow setting the following resistances: 50 Ω, 100 Ω, 300 Ω, 400 Ω and 600 Ω.

•

Monopolar test leads (connecting cable from NE socket to HF power meter with shorted jack plug, and laboratory cable with 4mm plugs for connecting the active electrode to the power meter).

•

Voltmeter with a measuring range of up to 200 V at a minimum.

•

Adjusting screwdriver.

KLS Martin maxium® / maxium® Beamer Service Manual If power setting is not possible, please check and make sure that the settings are correct on both the portable testing set and the HF unit. If the settings are correct, but the red LED UR lights up, the voltage setting may be too low. The arc regulator is active only while cutting tissue using the cutting currents Pure Cut, Uro Pure Cut, Soft Cut or Care Cut. It is not possible to activate this regulator via the HF power meter with its ohmic (non-reactive) load, as the direct-voltage component typically associated with the cutting process cannot be generated in this case. To obtain a control signal to which the optical link can be adjusted, it is therefore necessary to change the signal path: •

Check the screw connection at both ends of the optical fiber for tightness. The screws may only be finger-tightened; do not use tools!

•

Move jumper X6 next to the sender (transmitter) of the fiber-optic transmission link on the monopolar board to position 2-3 (set jumper to upper position). The yellow LED below the optical transmitter on the monopolar board, as well as the yellow LED FR on the power manager board, must come on as a result.

•

When rotating trimmer DCM clockwise, the LED FR remains bright; when rotating it counterclockwise, the LED grows darker. Adjust trimmer DCM to a point where the FR LED just starts growing darker.

•

Activate monopolar cutting with the previous Pure Cut setting (200 W). Rotate trimmer DCM counterclockwise until the power meter indicates HF power, then rotate trimmer DCM clockwise until the HF output power reading just reaches zero.

•

Reset jumper X6 next to the fiber-optic transmitter on the monopolar board to position 1-2 (move jumper back to lower position).

If it is not possible to set the trimmer so that the HF output power can be adjusted all the way down to zero, check the optical fiber for proper connection. It is likely that the fiber has not been fully inserted into the screw connection on one side. If mounted correctly, the fiber end penetrates into the connection for approx. 17 mm. And if the HF unit does not deliver any HF output power while the yellow LED FR lights up continuously, you likely forgot to re-set jumper X6 on the monopolar board.

10.2.2

Power Manager Boards III (from HW03) and IV (from HW06)

From HW03 onwards, the HF output voltage for most monopolar currents – with the generator at no-load – is no longer limited by the internal voltage of the regulator USO, but by the new HF output voltage regulator located on the monopolar board (identifiable by the yellow LED DCM). To set USO, the regulator on the monopolar board therefore must first be disabled. As a result, the checking and adjusting procedure differs a little from that applicable to power manager boards I and II: •

Disconnect the optical fiber from the monopolar board. This ensures that the output voltage regulator cannot be activated.

•

Connect voltmeter to measuring points VDC and GND on the main board.

KLS Martin maxium® / maxium® Beamer Service Manual If power setting is not possible, please check and make sure that the settings are correct on both the portable testing set and the HF unit. If the settings are correct, but the red LED UR lights up, the voltage setting may be too low. If the error message “Err 56” is displayed soon after current has been activated, the fault protection circuit has been triggered because the power setting is too high. In this case, rotate trimmer PSO fully counterclockwise, switch unit off and on again to clear the fault, and then set the power, starting from bottom of range. The arc regulator is active only during the process of tissue cutting using the Pure Cut, Uro Pure Cut, Soft Cut and Care Cut cutting currents. It is not possible to activate this regulator via the HF power meter with its ohmic (non-reactive) load, as the direct-voltage component typically associated with the cutting process cannot be generated in this case. To obtain a control signal for adjusting the optical link, the DC regulator located on the monopolar board is set to its lowest control position by adjusting the setpoint to zero and setting an actual-value offset: •

Reconnect the optical fiber to the monopolar board, inserting it fully (17 mm) into the connector, then finger-tighten screw. Do not use a tool!

•

Select Care Coag on ME402 and set it to an output power of 0. The yellow LED DCR located on the monopolar board – only faintly glowing to this point – must now light up together with the yellow LED DCM on the power manager board.

•

When rotating the DCM trimmer clockwise, the DCM LED remains bright; when rotating the trimmer counterclockwise, it grows darker. Adjust trimmer DCM to the point that the LED DCM just starts growing darker when rotating the trimmer counterclockwise.

•

Set power meter to 100 Ω. Activate monopolar coagulation, leaving Care Coag set to 0. Rotate trimmer DCM counterclockwise until the power meter indicates a low HF power level, then rotate trimmer DCM clockwise until the HF output power displayed just reaches zero. The VDC voltage will drop below 1 V during this process.

•

Thereafter, set Care Coag higher than 0 to ensure that HF power is available for subsequent measurements!

•

If it is not possible to adjust the trimmer so that the HF power can be regulated down to zero, a likely cause is that the optical fiber has not been fully inserted into the screw connection on one side. If mounted correctly, the fiber end extends into the connector for approx. 17 mm.

From HW06, the bipolar board also features regulators that are connected to a second fiberoptic receiver using a second optical fiber. To adjust this second receiver, proceed as follows: Select the Micro Coag bipolar current on the ME402 and set its output power to 0. This causes the yellow LED BRDC on the bipolar board and the yellow LED DCB on the power manager board to light up. •

When rotating trimmer DCB clockwise, the DCB LED remains bright; when rotating the trimmer counterclockwise, it grows darker. Adjust trimmer DCB to the point that the DCB LED just starts growing darker when rotating the trimmer counterclockwise.

•

Activate the Micro Coag current and rotate trimmer DCB first counterclockwise until a VDC voltage of approx. 8 V is displayed, then rotate the trimmer clockwise until the VDC voltage drops just below 1 V. Thereafter, set Micro Coag higher than 0 to ensure that HF power is available for subsequent measurements!

Setting the Monopolar Board

When replacing the monopolar board, the setting of the fiber-optic transmission link (optical link) must be checked and adjusted if necessary. Preadjustment is not possible in this case, as the efficiency of both the optical transmitter and the sensitivity of the receiver are subject to high manufacturing tolerances, which causes high spread in the coupling of the two components. The neutral electrode monitor, in contrast, has been factory-preset, so the setting usually needs to be checked for correctness only. The following tools and working aids are needed for this task: •

Voltmeter

•

Adjusting screwdriver

•

From monopolar board III: HF power meter (e.g. KLS Martin EPM3). This instrument should at least allow setting the following resistances: 50 Ω, 100 Ω, 300 Ω, 400 Ω and 600 Ω.

•

From monopolar board III: monopolar test leads (connecting cable from NE socket to HF power meter with shorted jack plug, and laboratory cable with 4mm plugs for connecting active electrode to power meter).

•

Optional: NE test plug (NE plug with built-in 270Ω resistor).

If the “slide” of the NE indicator moves unsteadily to and fro, this may be caused by a loose contact in the NE monitoring circuit (e.g., the contact force of the NE socket may be insufficient). If the fault cannot be corrected by adjusting the contact spring, the socket must be replaced.

Setting the Monopolar Boards III (from HW03) and IV (from HW06)

When removing or replacing this module, the setting (transfer characteristic) of the optical link and – from HW04 upwards – the operating point of the HF output voltage regulator must be checked for correctness. Spare boards are delivered with the NE monitor preset, so no readjustment is necessary in this case. Setting the operating point of the voltage regulator (for HW04 or higher) should obviously be done after the transfer characteristic of the optical link has been checked/adjusted according to section 10.2.2. Proceed as follows: Select Care Cut current at output M1 and set it to 1 (minimum). Set the HF power meter to 600 Ω.

•

Setting the Bipolar Board

Each of the two bipolar HF outputs has a monitor that measures impedance between the two electrodes. The results are used as inputs from which the main controller calculates a criterion for switching off the HF current (Auto Stop function) or activating the HF current (Auto Start, Auto Start/Stop functions). Replacement (spare part) boards are delivered with these monitors preset, so no readjustment is necessary. Up to and including HW05, only the output B2 incorporates an instrument code recognition function; from HW06, both bipolar outputs (B1 and B2) have this capability. The corresponding operating points are also preset on spare boards and need not be adjusted. To check the settings, the following tools and working aids are required: •

Voltmeter

•

10.4.2

Setting the Bipolar Board II from HW02 to HW05

Replacement boards are delivered fully preset. Impedance monitor setting is a little more time-consuming for bipolar module II than it is for bipolar module I, as the measuring signals are collected via connector X24 and a test adapter is needed to connect a voltmeter to connector X24. However, it is also possible to pick up the signals directly at the contacts of the connector if a sufficiently fine test tip or test terminal is used. With this module, there are two different regimes for setting the impedance monitors. Board versions V00 and V01 are set to resonance with the source circuit open, whereas versions V03 and higher are set to resonance when the source circuit is closed. The version number is indicated on the label with module number C40-2155. The board is available as a spare part only as version 03 or higher, i.e. set to resonance with closed source circuit. To check the settings of the impedance monitor of a bipolar board version V00 or V01 (resonance with open source circuit) in case of need, proceed as follows: •

Select the Macro Stop or Micro Stop current at the two bipolar coagulation channels and set them to minimum power.

•

Connect the bipolar test adapter to X24 on the bipolar board and the voltmeter to the test adapter, then set switch to UGL1 (alternative procedure: move jumper at X8 from position 2-3 (bottom) to position 1-2 (top) and connect voltmeter to X24.8 and GND (X16)). The PULS LED (B6) lights up as a result.

The operating frequencies of the bipolar board III are again set with trimmers, with separate procedures for the open source circuit and the closed source circuit.

This requires an HF power meter (e.g. KLS Martin EPM3). This instrument should allow setting at least the following resistances: 50 Ω, 100 Ω, 200 Ω, 300 Ω, 400 Ω and 600 Ω. The reference values to be used for comparison are the values measured initially as indicated in the Works Test Report (supplied with the unit). The measured HF output power values should not deviate by more than 20% both from these reference values and from the specified nominal output values. •

Connect the HF power meter to socket M1 (using a handle) and to the NE socket. Set power meter to 400 Ω. Select the Pure Cut current for M1 and assign both the yellow and the blue pedal to M1.

•

Set an output power of 10 W and activate the current. Check the reading on the power meter.

•


•


•

Select the Blend Cut current, set an output power of 320 W and activate the current. Check the reading on the power meter.

•

Select the Desiccation current and set an output power of 120 W. Set the power meter to 100 Ω. Activate the current, then check the reading on the power meter. Attention: In HW00 and HW01 units, this value may have changed more than other values due to software update.

•

Select the Contact Coag current and set an output power of 250 W. Set the power meter to 100 Ω. Activate the current and check the reading on the power meter.

•

Select the Forced Coag current and set an output power of 150 W. Set the power meter to 300 Ω. Activate the current and check the reading on the power meter.

•

For HW00 and HW01 units, select the Macro Spray current and set an output power of 150 W. Set the power meter to 1200 Ω. For HW02 and higher-version units, use the Spray Coag current and 600 Ω. Activate the current and check the reading on the power meter. Thereafter, activate the current and slowly but steadily reduce the output power down to 2 W, thereby verifying the correspondingly steady change that should take place in the value displayed on the power meter. Pay attention to internal (transient) disturbances!

If the deviation is high in HW00 and HW01 units for this operating mode (P < 120 W or P > 180 W), you can switch to an alternative table via the “Setup” menu item (select “Service” and enter the service access code “2020”) as described in section 4.1.5. There are three tables available (SPR0, SPR1, and SPR2), with SPR0 representing the basic (default) setting. If SPR0 provides insufficient power, you should switch to SPR1. If this still gives you less than 120 W, select SPR2. As a rule, you should select the table that is best suited for compliance with the specified tolerance range of 120–180 W. Such deviations are caused by a weakness in the driving circuit of the HF generator, which can be corrected by a hardware change if switch-over to another table will not help.

•

Connect the monopolar handle to output M2, then assign the blue pedal to M2 and select the Macro Spray current for this output, setting an output power of 150 W. Activate the current and check the reading on the power meter. The value displayed on the power meter should be identical to the M1 value, with deviation limited to 1 W at a maximum.

•

Connect the B1 bipolar output to the HF power meter using the bipolar test cable (for the “international” socket module, use laboratory cables; for the Erbe “e” module, use an adapter). Select Bipol Pure Cut at B1 and assign the yellow pedal, then select 300 Ω on the power meter. Set output power to 1 W and activate the current. Check the reading on the power meter.

•

Set output power to 120 W and activate the current. Check the reading on the power meter.

•

Select Micro Coag at B1 and assign the blue pedal. Attention: A software change has occurred here! For software versions up to 0.331b (only used in HW00 and HW01), 200 Ω are used for adjustment; from software version 1.336, the resistance value has been reduced to 50 Ω. Therefore, be aware that the adjustment value to be used is no longer identical with the one specified in the Works Test Record! Set output power to 50 W and activate the current. Check the reading on the power meter. The specified tolerance limit of 20% (regarding both the nominal value and the reference value measured initially) must be complied with in either case (200 Ω and 50 Ω).

•

Select Macro Coag at B1, then select 50 Ω on the power meter. Set output power to 120 W and activate the current. Check the reading on the power meter.

If the measured values deviate significantly from the values measured initially, the unit is probably defective. For safety reasons, the unit must be withdrawn from use and the cause of the malfunction investigated and removed before it may be clinically used again.

10.6

Checking Compliance with High-Frequency Leakage Current Limits

After repairs and as part of the periodic safety checks, it is mandatory to check the highfrequency leakage currents for compliance with the values measured initially (tolerance range: 20%) as well as with the specified limits. •

Set HF power meter to 200 Ω and connect one side to the ground conductor. Select Super Blend 250 W and Macro Spray/Air Beam 150 W for M1 und M2, respectively.

Insert shorting plug into NE socket und connect active output of M1 to power meter using test cable. Assign both the yellow and blue pedal to M1. Activate cutting. The permissible limit is 100 mA.

•

Activate coagulation. The permissible limit is 100 mA.

•

Connect test cable to NE socket and activate first cutting and then coagulation. The measured HF leakage current value shall not deviate from the value measured initially (reference value) by more than 20% and at the same time shall not exceed the upper limit of 100 mA, either.

•

Insert shorting plug into NE socket and connect M2 to power meter using the laboratory cable. Assign both the yellow and blue pedal to M2. Activate cutting. The measured HF leakage current value shall not deviate from the value measured initially by more than 20% and at the same time shall not exceed the upper limit of 100 mA, either.

•

Activate coagulation. The measured HF leakage current value shall not deviate from the value measured initially (reference value) by more than 20% and at the same time shall not exceed the upper limit of 100 mA, either.

•

Connect test cable to NE socket and activate cutting first, and then coagulation. The measured leakage current value shall not deviate from the value measured initially by more than 20% and at the same time shall not exceed the upper limit of 100 mA, either.

•

Select Bipol Blend Cut 120 W and Macro Coag 120 W for B1 and B2, respectively, on the unit to be tested. Connect one pin of the bipolar output to the power meter (for Martin coaxial socket, use adapter).

•

Assign both the yellow and blue pedal to B1. Activate cutting. The measured HF leakage current value shall not deviate from the value measured initially (reference value) by more than 20% and at the same time shall not exceed the upper limit of 77 mA, either.

•


•

Connect test cable to the other pin, then repeat measuring process.

•

Connect test cable to one pin of the bipolar output B2 (for KLS Martin test cable, use coaxial socket on adapter).

•

Recurrent Safety Checks according to IEC/EN 62353

As prescribed by IEC/EN 62353, the following safety checks and tests must be performed on the unit after repairs, and periodically at least every 24 months, by qualified persons who have the necessary training, knowledge and practical experience to carry out such work properly, responsibly and independently. If the ME402 is used in conjunction with an MB402 maxium® Beamer, then the Beamer must be checked as well. A: Visual inspection and functional checks 1. Rating plate and label legibility: All information provided on the rating plates of the maxium® and (if applicable) the maxium® Beamer must be clearly legible. The same applies to the rear-side labels, especially the nominal value information for the device fuses (T6.3A) located in the unit’s power supply socket. On the MB402 (Beamer), the information on the permitted pressure range – provided next to the gas inlet – must be clearly legible. 2. A copy of the Operating Instructions must be available for the current version of the system. Updated manuals can be obtained through the Gebrüder Martin Service Center. 3. Enter the software version number (V X.XXX) – as indicated on the initial screen displayed upon switching on the unit – in the Test Record sheet. Pay attention to potential error messages during the initial self-test. 4. Check both screen illumination tubes or proper functioning (uniform illumination of the screen). Check symbols and pictograms for clarity and correct color rendition (blue and yellow). 5. Visual inspection of all connectors: Check the HF connecting sockets M1, M2, B1 and B2 plus the NE socket for potential damage or defects. On the maxium®’s rear panel, check the footswitch sockets, the equipotential bonding pin and the maxium® Beamer connecting socket for potential damage and firm seat. Disconnect the power cord from the unit’s power supply socket and check the socket for potential damage and firm seat. Besides, remove the line fuses from the connector socket assembly and verify the fuse rating for correctness (T6.3 A, i.e. slow-blow). On the rear panel of the maxium® Beamer, check the socket for the connecting cable to the maxium® unit for potential damage and firm seat. Check the gas inlet, decompression pin and equipotential bonding pin for firm seat. On the Beamer’s front panel, check the gas outlet for potential damage and firm seat. 6. As far as possible, check the cables of all reusable accessories used with the unit(s) for insulation and plug damage. 7. With the unit turned on, check the sealed buttons (membrane switches) on the front panel of the maxium® for proper functioning. Upon operating a channel selector button, the red frame must jump to the channel’s Power field if the channel has already been selected, or this action selects the channel in the first place. Check all eight channel selector buttons. Also, verify that upon pressing the MENU button, the (bar-type) selection cursor is displayed at the top of the list on the right side of the display (first item highlighted). 8. Functional check of the rotary switch and its backlighting system: Upon selecting a cutting channel, the backlight must be yellow, and if you select a coagulation channel, the backlight must be blue. Operating the MENU button must change the color of the backlight ring to white. Rotate the switch to verify that the power value indicated for the selected channel

226

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual can be changed in this way. Press the switch to verify that the axial pushbutton function (“axial click”) is OK. A normal amount of pressure must suffice to perform the click and carry out the function (red frame disappears). 9. Checking the current activation feature, the activation indicators and the acoustic activation signal for proper functioning: Deactivate the NE alarm with the shorting plug, then connect the electrode handle successively to M1 and M2 and operate the two finger switches in each case. This must activate the HF current. At the same time, the activation LED belonging to the respective output (M1 or M2) must come on in the color of the activated operating mode (i.e. yellow or blue), and the activation signal must also be heard. In the case of multifunctional connectors, alternative accessories should be checked as well, inasmuch as they are also used. Connect the dual-pedal footswitch to the large footswitch socket, then check that the channels assigned to it are correctly activated when operating the yellow or blue pedal, respectively (if necessary, assign the footswitch pedals first). Thereafter, connect the single-pedal footswitch to the small footswitch socket and verify that operation of the footswitch activates the channel assigned (again, assign footswitch first if necessary). Connect the bipolar test cable to the bipolar outputs B1 and B2 (one after the other), then select a coagulation current with auto-start function and set it to minimum power in each case. Now check that bipolar coagulation current is activated when shorting the banana plugs and deactivated when opening the contact. Subsequently, connect the bipolar test adapter to output B2 and verify that current can be activated with the finger switches on the handle. 10. Checking the neutral electrode monitoring system for proper functioning: When the NE connecting socket is open, the split neutral electrode symbol must be displayed in red and the slide of the graphical NE indicator (which must first be enabled via the menu if not displayed yet) must be at the left end of the bar graph. Upon activating a monopolar channel (via an electrode handle connected to M1 or M2), the intermittent NE alarm signal must now be clearly heard. Insert the shorting plug. The non-split (single-plate) NE symbol must now be displayed in green and the slide symbol must disappear. Insert the test plug with a resistance of 270 Ω. The slide of the bar-type NE indicator must now be in the range of the yellow field. 11. If a maxium® Beamer is connected, switch off the maxium® HF unit, then disconnect the argon gas supply line from the maxium® Beamer (if applicable) and turn on the maxium® again. The Standard program must now be displayed without argon current and the Beamer indicator must remain dark. Select an argon-supported current on one of the monopolar channels. The Beamer indicator must now turn red. If necessary, the maxium® unit must first be configured for maxium® Beamer operation via the “Argon” menu item. Reconnect the gas supply line to the gas inlet of the Beamer. The self-test must now be started. Upon its completion, the indicator must turn green. 12. Operate the PURGE button. This must activate a gas flow without HF current for 3 seconds. This function is used to clear the air from the applicator prior to use. 13. Checking Beamer activation and Beamer activation indicators for proper functioning: Select an argon-supported cutting current and an argon-supported coagulation current on the maxium®, then activate them one after the other. Upon activation, the Beamer indicator must light up either yellow or blue, depending on the type of current activated.

227

KLS Martin maxium® / maxium® Beamer Service Manual 14. Checking the Beamer’s argon gas flow for continuous increase: Usually, an argon-calibrated flow meter will not be available. Anyway, as the user will control the gas flow according to the observed surgical result rather than by (abstract) measured values, it is enough simply to check the continuous adjustability of the gas flow. Connect an argon applicator to the Beamer, not to the maxium® HF unit! Now activate an argon-supported current at flow rates of 0.3 l/min, 1 l/min, 3 l/min and 10 l/min in this sequence and verify by ear (judging by the blowing noise) that the gas flow increases adequately from step to step.

B. Safety measurements according to IEC/EN 62353 The IEC/EN 62353 standard specifies two different procedures that can be used for verifying electrical safety. One option are direct measurements based on the type approval standard EN 60601. This procedure utilizes the mains voltage used for operating the unit under test to check the safety-relevant isolating distances for compliance with standard specifications. The second option are equivalent measurements, in which case the safety-relevant isolating distances are loaded with a voltage source integrated into the test instrument. The direct measurements are frequently carried out with an automated safety tester that switches the mains voltage off and on several times during the automatic testing procedure. Note, however, that the hardware versions 00 and 01 of the maxium® require a special procedure because the unit remains switched off after a power interruption. You have two options here – either to perform the measurements manually, in which case the unit under test must be switched on manually after each power interruption, or to set jumper X10 to position “1-2” on the power manager board. While the latter option keeps the unit switched on permanently, it requires you to open the unit, of course. As from hardware version 02, the unit remains switched on after a power interruption, provided the interruption does not exceed 4 seconds. Alternatively, the checks can be performed by way of equivalent measurements in the meaning of IEC/EN 62353. In this case, it is not necessary to move the jumper on the power manager board. All applicable measurements should be performed either as direct or equivalent measurements. For the recurrent (periodic) safety checks, the following measurements must be carried out: 1. Measure protective conductor resistance between the protective conductor (PE) contact and the equipotential bonding pin of the maxium®, or between the protective conductor contact and any other touchable part of the unit connected to the protective conductor, using a current of 200 mA at a minimum. The resulting value shall not exceed 0.2 Ω measured at the unit’s mains connector socket, and 300 mA measured at the plug of the power cord. 2. Ground leakage current, normal case: Direct measurement of the current in the protective conductor of the power cord without fault simulation. The measured value shall not exceed 1.5 times the value measured initially (reference value) as indicated in the Works Test Report supplied with the unit. At the same time, it shall not exceed the absolute upper limit of 500 µA, either. Not applicable when using the “equivalent measurement” procedure. 3. Ground leakage current, single fault: Direct measurement of the current in the protective conductor of the power cord while simulating an interruption of the ground-related phase N (this switches off the unit). The measured value shall not exceed 1.5 times the value measured initially (reference value) as indicated in the Works Test Report supplied with the unit. At the same time, it shall not exceed the absolute upper limit of 1,000 µA (1 mA), 228

V 5.0

KLS Martin maxium® / maxium® Beamer Service Manual either. This value is usually twice as high as the measured normal-case ground leakage current. Not applicable when using the “equivalent measurement” procedure. 4. Contact current (housing leakage current), normal case: Defined as that current which flows from the maxium®’s equipotential bonding pin, as well as from any externally touchable part of the unit, to ground. As this current path constitutes a parallel path to the protective conductor, its value is undefined because it depends on the variable relationship between the two part grounding resistances involved. The measured value shall not exceed the upper limit of 100 µA. For equivalent measurement, this current is defined as the current which – driven by a test voltage source – flows between the mains input socket and the protective conductor or any externally touchable part of the maxium®. The measured value shall not exceed 1,000 µA (1 mA). 5. Contact current (housing leakage current), single fault protective conductor: This is equivalent to the directly measured normal-case ground leakage current because the test path now functions as a protective conductor. The measured value shall not exceed 1.5 times the value measured initially (reference value) and not exceed the absolute maximum of 500 µA, either. Not applicable when using the “equivalent measurement” procedure. 6. Contact current (housing leakage current), single fault mains: Defined as the directly measured current flowing from the equipotential bonding pin of the maxium®, as well as from any externally touchable part of the unit, to ground upon interrupting the groundrelated phase N (which switches off the unit). As this current path constitutes a parallel path to the protective conductor, its value is undefined because it depends on the variable relationship between the two part grounding resistances involved. The measured value shall not exceed the absolute upper limit of 500 µA. Not applicable when using the “equivalent measurement” procedure. 7. Patient leakage current, normal case: For direct measurement, this is the current flowing from the instrument connectors M1, M2, B1, B2 and NE to ground in non-activated condition. A limit value of 10 µA shall apply. When using equivalent measurement, this is the current which – driven by a test voltage source – flows from the applied parts to externally touchable parts of the maxium® and to the mains input socket of the unit. A limit value of 50 µA shall apply. In both cases, the measurements can be performed by paralleling several connectors as long as such parallel connection does not lead to a measured value that exceeds the specified limit value. Should this be the case, the monopolar and the bipolar applied part must be tested separately and the highest value measured entered in the Test Record sheet. Please note that shorting the bipolar output B1 or B2 will cause an error message during the self-test performed after switching on the unit. This leaves two options: Either you can use test cables connected to only one pin of the outputs B1 and B2, or you can perform the measurement manually after the initial self-test has been completed. In this latter case, however, no current with auto-start function must have been selected! 8. Patient leakage current, single fault protective conductor: Direct measurement of the currents from the instrument connectors M1, M2, B1, B2 and NE to ground in non-activated condition and with the protective conductor interrupted. The upper limit not to be exceeded is 50 µA. Besides, the provisions given under item 7 shall apply. Equivalent measurement not possible.

Patient leakage current, single fault voltage at applied part: Direct measurement of the currents from the instrument connectors M1, M2, B1, B2 and NE to ground in non-activated condition after a ground-related test voltage has been externally applied to the maxium®’s connectors via the power meter! The upper limit not to be exceeded is 50 µA. Besides, the provisions given under item 7 shall apply. This test corresponds to the equivalent measurement performed according to item 7 above.

C. Measuring output power The HF output power should be measured and verified for exemplary currents. This is intended to check the HF current paths of all available outputs (M1, M2, B1 and B2) for proper functioning.

All safety checks and related results must be documented in the equipment log!
