Introduction This manual provides detailed information for operating the FES Micro III System Panel. Note that each System Panel is customized for a specific application. Therefore, FES will provide documentation and drawings that apply to that particular product. Some of the displays presented in this manual will not be available in a particular application. In this document, the user will be introduced to material common to all Micro III System Panels. Stock options like Compressor Sequencing or Condenser Control will be documented with an addendum that describes the added features. Custom options (application specific) will also be documented with an addendum.

Micro III Keypad Interface Units shipped prior to February 2001 may not have the lower row of keys.

NOTE: Keypad Lockout is available as an option for the Micro III. The Keypad Lockout option provides a key switch to prohibit unauthorized changes to Micro III parameters, or totally disable the Micro III keypad (dip switch selection). The following examples assume that Keypad Lockout is disabled or not installed.

DISPLAY FUNCTION KEYS Located to the right of the display, these keys allow the user to interact with the Micro III displays. Pressing the [CHANGE DISPLAY] key, for example, will move the user to the next display group. Pressing the [ALT] key following by the [CHANGE DISPLAY] key will cause the user to move to the previous display group (for an understanding of the [ALT] key, reference the ALT key section)1. In display groups with multiple entries, the [×] and [Ø] keys allow the user to move the cursor and cause the display to scroll. The [Õ] and [Ö] keys can be used to step forward and backward by topic while

Keypad in a parameter display group. The [Õ] and [Ö] keys can also be used to Page Down and Page Up in the Analog Data and Digital Data display screens. To change an entry in a parameter display group, place the cursor on the appropriate entry and press the [EDIT] key. Use the Data Entry keys to enter an appropriate value. If an error is made during entry, press the [CLEAR] key to start entry again. Press [ENTER] after the entry is made. If the new entry was within range limits, it will be accepted. If it was outside range limits, the last line of the display will indicate 'Minimum =' or 'Maximum =' and the entry will be rejected. If the user wishes to accept the old value, press the [EDIT] key again.

DATA ENTRY KEYS Located on the lower right of the keypad/display overlay, the Data Entry keys [0] through [9] are used for entering numeric data. Press the [+/-] key to enter pressures in a vacuum, or negative temperatures. On panels manufactured February 2001 or later Keys [1A] through [6F] have hexadecimal characters in the lower left corner, to enter a hex character for ComMENT addresses press the [ALT] key and the key with the desired hex value on it. The indicator on the [ALT] key will light when the key is pressed and go off after the hex key is pressed. The [.] and [+/-] also have new legends, [. CHANGE] and [+/-SKIP] to aid in navigation of the Historical Data and Digital Data screens, refer to the respective pages for their use.

SPECIAL FUNCTION KEYS Located below the Micro III's display, the Special Function Keys may be configured to provide convenient access to a setting, or visual feedback about an event. An application specific legend may be provided to label the keys and LED's. An addendum will be provided to document the use of these keys if the factory configuration requires them.

ALARMS KEY The [ALARMS] key is usually located at the lower left corner of the Special Function Key area, it may be relocated if required during a factory configuration. If an Alarm annunciation is present, the LED for the [ALARMS] key will flash. Use the [CHANGE DISPLAY] key to cycle through displays until the Alarms Display is visible, or press the [ALARMS] key for direct access. In the Alarms Display Group, the [CLEAR] key is used to remove individual (acknowledge) alarm messages once a resolution has been made. If an external device like a siren or horn is connected to the panel, the [ALARM OFF] key is used to silence the warning once the user has been alerted.

ALT KEY AND SPECIAL FUNCTION KEYS Located at the bottom of the keypad this group of keys was added to the Micro III starting in February, 2001. Control panels built before this date may not have this group of keys. The eight new special function keys have the same functionality as the group of sixteen below the display. The [ALT] key works like a ‘Shift’ or ‘Function’ key to double the number of available keys for special configurations. The [ALT] key is used to access any of the functions on the keypad that are in blue print, for example [A] – alternate function to Data Entry key [1]. Pressing the [ALT] key will illuminate its LED. While the [ALT] LED is illuminated, pressing any of the keys with blue print will take that action. For example, to enter an alpha-numeric “A”, the [ALT] key would be pressed (LED illuminated) followed by the [1] key. The hexadecimal characters A-F are used to simplify Sequencing setup, refer to the Sequencing Addendum for details. Note, the [ALT] LED will only stay illuminated until another key is pressed, 1 minute passes before another key is pressed, or the [ALT] key is pressed again. 1

Applies only to software Revision 6.7 or later.

Hardware POWER SUPPLY The power supply has a +5VDC adjustable setting. Before adjusting the voltage, set the control power switch to the off position. Next, unplug the power supply connector from the lower left of the processor board. Set the control power switch to the on position. Because it has no load, the power supply will "chirp" repeatedly.

Micro III Power Supply

Measure the +5VDC supply between the +5V and ground terminals on the power supply. Use a small flat-blade screwdriver to adjust the voltage between 5.00 and 5.10 Volts DC. Note that the power supply's "crowbar" protection will activate above 5.60 VDC, which will cause it to shutdown. To reset the crowbar, turn the control power switch to the off position and adjust the voltage potentiometer to its lowest setting. Set the control power switch to the off position and plug the power supply connector into the processor board. Turn the control power switch to the on position and verify the +5VDC, +12VDC, 12VDC, and +24VDC power supply voltages. The +12VDC, -12VDC, and +24VDC supply voltages are non-adjustable and should be within +5% of nominal (+11.4 to +12.6, -11.4 to -12.6, +22.8 to +25.2, respectively). If they are not, replacement of the Micro III's power supply will be necessary.

PROCESSOR BOARD BATTERY REQUIREMENTS AND REPLACEMENT The user's Parameters and Calibrations are retained in a non-volatile (power independent) memory. Only clock functions are affected by low battery voltage. If the real time clock cannot be set, if it fails to maintain the proper time and date when the control power switch is off, or if a Real Time Clock Fault appears in the Alarms Display, battery replacement may be necessary. Use RAY-O-VAC BR2325-1, 3 volt lithium battery or equivalent for replacement.

Hardware DISPLAY CONTRAST ADJUSTMENT Due to differences in ambient lighting, it may be necessary to adjust the display's contrast once the compressor package has been installed. This can be accomplished via the 'DISPLAY ADJ.' potentiometer located on the upper right of the processor board, near the keypad/display ribbon cable.

Communications NODE ID Rotary switches SW4 and SW5 set the Node ID for ComMENT Network communications or Micro III Direct communications. These rotary switches register the number or letter near the index mark on the switch's base. The Node ID selection is read from the rotary switches during power up or reset only. A Node ID of '05', for example, would be established by setting SW4 to '0' and SW5 to '5'. Please refer to MCP-003 for a full explanation of the ComMENT Network and MCP-161 for Micro III Direct Communications. A Node ID of '00' is invalid and must not be used. When assigning Node ID's, remember that each ComMENT Network Node must have its own unique ID.

LINE VOLTAGE FUSE F1 The line voltage fuse is retained using spring clips near the left side of the processor board. This fuse protects the circuitry that measures the incoming line voltage. Be sure to de-energize the circuit breaker powering the microprocessor before checking fuse F1. Placing the control power switch in the off position does not remove power from fuse F1. If fuse F1 is open, replace it with LittlefuseTM #225.250 (2AG, 1/4 Amp). Fuse F1 opening repeatedly may indicate a problem with the processor board circuitry.

ANALOG OVERCURRENT RESET The analog over current circuitry is located on the lower left side of the processor board. The LED next to the analog terminals (P9) glows green normally. If excessive current is drawn by a sensor connected to P9, the analog over current circuitry will interrupt the +24VDC supplied to the sensors and the LED will glow red. If the analog over current circuit is tripped, the user should examine the analog sensors and related wiring for shorts. Once the fault has been discovered, press the Analog Over Current Reset button SW7. If the fault has been removed, the LED will glow green. Note that sensors powered by +5VDC (channels 1 through 6, when J17 is in the upper position) are not protected from over current.

ANALOG INPUT JUMPERS The Micro III processor board has 16 channels of analog input. The factory-configuration defines the purpose and scaling for each of these inputs. Each input has jumpers to make it electricallycompatible with 0-5V, 1-5V, 4-20mA, and ICTD (integrated-circuit temperature device) signals. In addition to the these selections, channel 8 can be fitted to a potentiometer for slide valve indication and channel 16 can be interfaced to a 0-5Amp current transformer. To simplify sensor wiring, each input has terminals for analog power and ground. For the channels 1 through 6, J17 can be used to select an analog power supply of +5VDC for ratiometric pressure transducers (J17 in upper position) or +24VDC (J17 in lower position). The analog power supply for the remaining channels is fixed at +24VDC.

Table of Processor Board Analog Input Terminals and Configuration RS-232 / RS-422 SERIAL COMMUNICATION PORTS At present, the RS-232 port (P5) is used by the factory for downloading software to the Micro III processor board. J10 must be in the upper position for RS-232 communication. Jumpers J9 should be set to the upper position, and J11 to the lower, for DTE configuration. Reverse J9 and J11 for DCE configuration. For future RS-422 use, move J10 to the lower position. Starting with Software Revision 7.1, this port is also used for Direct Communications. Please refer to MCP-161, Micro III Direct Communications, for a full explanation.

ANALOG OUTPUT CONFIGURATION The Micro III has 4 channels of analog output. The factory-configuration defines the purpose and scaling for each these outputs. For a specific application, these outputs may be used to control a variable speed fan, or modulate a control valve. In addition to the software configuration, optional hardware components must be installed to use the analog outputs. To use any of the analog outputs, two HP2231 optocouplers must be installed in the two 8-pin sockets above current transformer T2. In addition, an AD420AN transmitter must be installed for each channel required. Next to each of the AD420AN's is a potentiometer to adjust its span (the upper pot) and zero (the lower pot). If span adjustment is desired, remove the jumper from the pins immediately above the span pot (J50, J51, J52, J53). To fix the span at 16mA exactly, install a jumper immediately above the span pot (J50, J51, J52, J53).

Hardware With J62 in the upper position and J63 installed, the Micro III's +24VDC power supply will energize the 4-20mA current loop (all four channels). External devices connected using this configuration must have fully differential inputs (not referenced to ground). If ground isolation is necessary, move J62 to the lower position and remove J63. Apply an external floating +24VDC source to A59 (positive) and A60 (negative). Channel Number 1 2 3 4

OPTIONAL MICRO III EXPANDER BOARD Some applications of the Micro III require more Analog inputs, Analog outputs, or Digital I/O than is available on the Micro III main board. In these applications, an expander board is connected to the Micro III main board. This expander board can be connected to the Micro III Main Board directly via connector P1 or indirectly through the Rack Expander Board via connector P1. Connecting this board does not affect the general behavior of the panel. The only screen that is affected with the addition of the expander Board is the Digital Data Screen. For proper operation of the board and explanations of the additional jumpers and connectors, please refer to MCP-138, Micro III Expander Board.

OPTIONAL MICRO III RACK EXPANDER BOARD Some applications of the Micro III require more Digital I/O than is available on the Micro III main board with an Expander Board or only Digital I/O is needed (not Analog inputs/outputs that are present on the Expander Board) then a Rack Expander board is required. The Rack Expander board is connected to the Micro III main board through connector P1. Connecting this board does not affect the general behavior of the panel. The only screen that is affected with the addition of the expander Board is the Digital Data Screen. For explanations on proper operation of the board, please refer to MCP-165, Micro III Rack Expander Board.

Example Alarms Display The Micro III will retain alarm annunciations until manually cleared, even through power failures. To silence the Alarm Horn (if provided), press the [ALARM OFF] key, the annunciations will remain on the screen but the horn will be silenced. To clear an alarm annunciation, first resolve the source of the alarm. Next, position the cursor on the alarm to be cleared using the [×] and [Ø] keys, then press the [CLEAR] key. The alarm will re-appear if it has not been properly resolved. The following is a list of possible alarms in a standard panel. Application specific alarms will be described in an addendum to this manual.

Alarms Display Analog Calibration # -- The microprocessor detected an Analog Calibration outside its entry limits. The number after the annunciation indicates which analog channel's calibration is in error. Refer to Hardware's Table of Processor Board Analog Input Terminals and Configuration. Note that this alarm cannot be cleared until the error is corrected (channel re-calibrated). Panel Setup Parameters # -- The microprocessor detected a Panel Setup Parameter outside its entry limits. The number after the annunciation indicates which Panel Setup Parameter is in error. In the Panel Setup Display, out-of-range parameters will flash until corrected. Note that this annunciation cannot be cleared until the error is corrected (valid Panel Setup Parameter entered). Low Line Voltage # -- The line voltage powering the processor board dropped below the factoryconfigured trip voltage, for a minimum number of line cycles. Typically, these are set to 92Vrms and 4 line cycles. The number following the annunciation is the line voltage at the time of the annunciation. This annunciation is intended to be a warning that external devices controlled by the Micro III may malfunction as a result of low control voltage.

Page 15 of 81


Displays Operating Parameters # -- The microprocessor detected an Operating Parameter outside its entry limits. The number after the annunciation indicates which Operating Parameter is in error. In the Operating Parameters Display, out-of-range parameters will flash until corrected. This annunciation cannot be cleared until the error is corrected (valid Operating Parameter entered). Note that this alarm will not be issued if the Operating Parameter Display is disabled. Event Timer Parameters # -- The microprocessor detected an Event Timer Parameter outside its entry limits. The number after the annunciation indicates which Event Timer Parameter is in error. In the Event Timers Display, out-of-range parameters will flash until corrected. This annunciation cannot be cleared until the error is corrected (valid Event Timer Parameter entered). Note that this alarm will not be issued if the Event Timer Display is disabled. kWh Monitor Parameters # -- The microprocessor detected a kWh Monitor Parameter outside its entry limits. The number after the annunciation indicates which kWh Monitor Parameter is in error. In the kWh Monitor Display, out-of-range parameters will flash until corrected. This annunciation cannot be cleared until the error is corrected (valid kWh Monitor Parameter entered). Note that this alarm will not be issued if the kWh Monitor Display is disabled. Real Time Clock Fault – One of the values read from the Real Time Clock chip by the microprocessor was invalid. As a result, the clock values have been set to a default condition. Please refer to the Hardware Section of this document under the heading PROCESSOR BOARD BATTERY REQUIREMENTS AND REPLACEMENT for assistance in determining the cause of this alarm. Units Err Math Block # – One of the internal math functions is not configured correctly, contact FES. Overflow Math Block # – One of the internal math functions result was greater than 32767, a malfunctioning transducer could cause this error if the output is used in a math function. If all transducers and analog values are correct one of the internal math functions is not configured correctly, contact FES. Underflow Math Block # – One of the internal math functions result was less than -32768, a malfunctioning transducer could cause this error if the output is used in a math function. If all transducers and analog values are correct one of the internal math functions is not configured correctly, contact FES. Div by 0 Math Block # – One of the internal math functions is not configured correctly, contact FES. Stndrd Alarm Overflow – This alarm indicates that more alarms occurred than could be contained on the Alarms display (15 maximum). When the Standard Alarm Overflow alarm occurs, it overwrites the 15th alarm and the auxiliary information for this new alarm is the alarm code of the overwritten alarm. The time of the Standard Alarm Overflow alarm is the time that the first overflow situation existed and will not be changed with new alarms that occur while the Alarms display is full and this alarm exists. If the Alarms display is full and an alarm occurs that has control functions based on its presence in the Alarms display, those functions will operate as though the alarm was on the display. Clearing the Standard Alarm Overflow alarm will perform the same function as clearing the monitored alarm from the Alarms Display.

Communications Protocol The Micro III control panel has on-board ComMENT Network communications, allowing it to be interfaced to a wide variety of communication devices with ease. Since the FES ComMENT Gateway (optional) translates ComMENT Network transactions into Allen-Bradley DF1tm, GE SNPtm, or Modicon Modbustm, off-the-shelf drivers can be used to interface PLC's, supervisory computers, or building automatic systems. To an external device communicating with the Gateway, the Micro III's on the FES ComMENT Network appear to be PLC's in a multi-drop configuration. FES document MCP-3 'ComMENT Network Installation & User's Manual' should be referenced for installation instructions. The following table documents the data available at various registers within the Micro III's ComMENT Network Database. Note that the data registers for all Micro III options are shown, but the options may not be enabled in the factory. The Micro III panel also has available direct communications. Please refer to MCP-161, Micro III Direct Communications for a full description. Note that the data registers are the same for the ComMENT Network or the Micro III Direct Communications. The addresses shown are for System Panel Software Revision 7.5, all addresses may not be present in earlier revisions.
