3 System Descriptions The BS-300 analyzer consists of the analyzing unit, operation unit and output unit. The analyzing unit consists of the dispensing system, feeder, temperature control system, photometric system and fluid system.

3.1

Dispensing System The dispensing system consists of the probe assemblies (including the reagent probe assembly, sample probe assembly and mixing bar assembly), reagent disk, sample disk and reaction disk.

3.1.1 Probe assemblies Among the probe assemblies, the mixing bar assembly is the same as the reagent probe assembly and the sample probe assembly, except that the knurled axis is 30cm shorter.

Every probe assembly has a horizontal photoelectric switch and a vertical photoelectric switch. These switches are used for defining horizontal and vertical

3-1

System Descriptions initial positions of probe assemblies. The horizontal and vertical step motors precisely control the horizontal and vertical movements of the probe assemblies, and the synchronizing belts serve as the gearing. The shaft and the bushing must corporate with each other precisely, so they cannot be used confusedly.

3.1.2 Disk assemblies The three disk assemblies are different in their coders. The coder corresponds to the position where disks should stop. There is an initial-position mark under every coder. The three coders of the three disks have three coder transducers. Each transducer has two photoelectric switches for inducing the rotation and initial position of the disk.

The step motors control the disk assemblies, and the synchronizing belts serve as the gearing.

3-2

System Descriptions There is a build-in bar code scanner to the left of the sample disk. The scanner is optional.

3.3

Temperature Control System

3.3.1 Temperature control assembly The temperature control assembly of the reaction disk consists of the temperature-controlled pot, heat-insulating sheath/plate, top heater, bottom heater, reaction disk/cuvettes, photoelectric seat, temperature transducer, fan and control circuit.

3-5

System Descriptions

1: Temperature transducer and the support 2: Fan 3: photoelectric seat 4: Heat-insulating sheath 5: top heater 6: Cover 7: temperature-controlled pot 8: bottom heater

Upper heater: square in shape, 220/110VAC, 125W Lower heater: ring in shape, 220/110VAC, 350W Total power: 475W. The function of heaters is to compensate the heat for incubating the reagent and for maintaining the temperature of the temperature-controlled chamber. Fans are used in series in the temperature-controlled chamber. It makes the air circulating in the chamber, and enhances the convective heat exchange. There are four fans in the chamber. All have the alarm function. The temperature transducer feeds back the air temperature at the position several millimeters from the bottom of the reaction cuvette. The overheat protection switch is to switch off the power when the temperature controller does work and the temperature-controlled chamber reaches 55 ℃, so as to avoid overheat or fire. When the temperature-controlled chamber becomes 35 ℃, this switch will automatically be reset.

3.3.2 Reagent preheating The preheating assembly consists of two aluminum plates, a Teflon tube having nine loop sections, heating components, transducer, temperature protection switch, thermal conductive colloid, a section of tube and the reagent probe. The temperature of the thermal source of the preheater is controlled at 45 ℃. The initial temperature of the reagent is 4 ~ 10 ℃ when it is taken out of the refrigeration

3-6

System Descriptions chamber. When the reagent passes the heater, its temperature increases to 35 ℃. Then the reagent is added into the reaction cuvette and the preheating process is finished.

Reagent preheating assembly

3.3.3 Reagent refrigeration The refrigeration module consists of refrigeration cabin, PU heat-insulating sheath, reagent disk, reagent bottle, temperature transducer, refrigeration flakes, heat sinking component, fan and control circuit. The refrigeration module is shown in the following figure.

A/D Conversion Board The 10 photoelectric conversion circuits convert the intensity signals of the lights transmitting through the reaction cuvettes to electric signals, and then transmit them to the A/D conversion board through a 5-core shielded cable. Photoelectric conversion boards for different wavelengths have different gains and cannot be replaced by each other. The A/D conversion board filters and amplifies the 10 channels of electric signals output from the photoelectric conversion boards, transmits them through the multi-way gating switch to the A/D converter and then sends them to the main control board for further processing.

4.4

Reagent Refrigeration Board The circuits of the reagent refrigeration board include the refrigeration circuit and the fan circuit. The refrigeration circuit is needed to work continuously, so it is powered separately. The control objects of the reagent refrigeration board include: Reagent refrigeration: 2 PELTIER components, 4 fans.

Power Supply Assembly The power supply assembly consists of three boards: PFC board, 24V board, 12V&5V board and ISE (optional) power supply board. The functions of the PFC board include: 

AC/DC conversion;



Supplying the +390V and VDD voltage to the 24V board and the 12V&5V board;



Supplying stable 12V voltage for the lamp;



Supplying control signals of the analyzing unit switch to control the C12V, 5V and 24V outputs.

The 24V board converts the 390VDC current transmitted from the PFC board to the separated 24VDC outputs through the forward converter.

4-4

Functions of Boards The 12V&5V board converts the 390VDC voltage from the PFC board to B12V, C12V and 5V voltages through the forward converter. The ISE power supply board converts the 12V of the reagent refrigeration board to 24V that provides power supply for the ISE unit (optional).

Software Introduction

6 Software Introduction The software of BS-300 analyzer is composed of the system software and the control software.

6.1

System Software The system software can, according to the requirements and inputs of users, generate a work schedule (instruction sequence), control the units of analyzing unit in the sequence of instructions in the work schedule, receive photoelectric data, response messages or execution results from the analyzing unit, output them to the PC screen or the printer. With these outputs, users can obtain correct test results. According to different functions, the entire PC software system can be divided into the following parts: 

System Initialization

This part includes the initialization of the PC operating system, the initialization of the communication between the PC and analyzing unit, and the controls of analyzing unit reset. 

Control system

This part includes the formation of the work schedule, instruction data sending and receiving. 

GUI

This part includes the requests for tests (routine tests, emergency tests, calibration tests and QC tests), the observation of test status (status of the reaction disk, sample disk and reagent disk), test management, calibration management, QC management, result query, alarm management and the help system. 

Shutdown Processing

This part includes the resets of sub-units.

6.1.1 System initialization To initialize the PC operating system, 

Check the PC operating system. The system software must run under Windows 2000 or Windows XP. Otherwise, the system will prompt that the system software cannot run under other operating system, and then the system software system exits automatically.



Check the current screen resolution for the operating system. The system software must run under the resolution of 1024 × 768. Otherwise, the system prompts to reset the resolution before restarting the system software and exit the system software.



Disable the screen protection program. The system software must keep displayed while running. To prevent the screen protection program from disturbing users in the operating and observing processes, disable it.



Lock the keyboard. When running, the system software will lock some key combinations to prevent users from starting any other program and conducting any

6-1

Software Introduction other operation. In this case, users cannot switch over to any other program or print the current screen. 

Check whether there is any username and password of the maintenance/debugging personnel in the registry. The system software has the debugging function. Only the authorized maintenance/debugging personnel can enter the debugging window and maintain or debug the system and the host. For the confidentiality, the username and password are saved in the registry. If they are unavailable in the registry, the system will re-write the default username and password into the registry.

To initialize the communication and the units auto-check, 

Set serial ports and initialize them, including such parameters as the baud rate, data bit, start bit, stop bit, parity bit, transmitting/receiving buffer, control protocol and so on. In addition, start the serial port receiving thread.



Handshake for communication. Send a handshake instruction to the analyzing unit. If the analyzing unit responds to this instruction (namely, send back a handshake instruction to the PC), it indicates the PC handshakes with the host successfully. If the host fails to respond to handshake instruction, it will re-send the handshake instruction back in a specific period. If it fails for continuously three times, the system will prompt to exit the system software. If you ignore that and continue to enter the system software, all tests cannot be conducted under the system.



Check whether the printer is connected. If not, the system will prompt to connect it.



Send an instruction for querying the auto-check results of the units, check the auto-check result of each unit. (The units are auto-checked when the analyzing unit is started, and the auto-check results are stored in the main unit.) In case of any fault data in the auto-check result of any unit, the system will prompt to switch off the analyzing unit and check the faulty unit.

6.1.2 Shutdown processing In the BS-300 Chemistry Analyzer Control System window, click the Exit button. The Confirm dialog box appears. If you click OK, the system will

6.2



Switch off the lamp;



Unload all reaction cuvettes;



Wash the fluid tubing;



Reset all units;



Unlock the keyboard;



Prompt to exit the operating system and shut down the PC.

Control Software The analyzing unit can be functionally divided into the following units: photoelectric unit, reaction disk unit, reagent disk unit, sample disk unit, reagent probe syringe unit, sample probe syringe unit, mixing bar unit, loading and manipulator unit, temperature control unit, fluid tubing unit and reagent refrigeration unit. The functions of those units are listed in the following table.

7.1

Fluid Level Detection Failure of Reagent Probe Surface detection signal transmission error: The surface detection board does not have the working voltage, or when the probe touches the surface, the indicator of the surface detection board is normal, but there is always a host alarm indicating surface detection failure. Possible cause: The patch cord for the reagent surface detection is disconnected, or the connector is not well connected.

The reagent probe cannot detect the surface on the reagent disk

Surface detection failure of reagent probe(Th e reagent probe does not detect the surface on the reaction disk.)

Surface detection signal processing error: When the probe touches the surface, the indicator of the surface detection board is normal, the connection between the main control board and the surface detection board is normal, and no surface detection signal reaches the main control board, but there is always a host alarm indicating surface detection failure. Possible cause: Main control board. Power failure: The working voltage of the surface detection board is 12V. In case of no power supply, the surface detection signal cannot be generated. Possible cause: Disconnection; the connector is not well connected; there is no 12V output from the main control board. Probe failure: The detection terminal has a changeable capacitance. Loose exterior or interior of the probe, the sealing-off of the probe connecting wire and the probe breakage will result in unsteady voltage or obvious voltage changes. In this case, the capacitance signal will be unavailable or exceed the range of the surface detection board. Possible cause: Reagent probe assembly, connector.

The surface detection signal fails to be generated by capacitance change.

Surface detection board failure: When there is no probe failure, but the indicator is always on, or the indicator is not on when the probe touches the surface, there must be a surface detection board failure. Troubleshooting: Replace the surface detection board.

The reagent probe misdetected the surface

When this failure occurs, the sample probe cannot detect the surface at the reaction disk, but there is no alarm at the reagent unit. For details, see Surface Detection Failure: Sample Probe.

7-1

Service Flow

7.2

Fluid Level Detection Failure of Sample Probe

The sample probe cannot detect the surface at the reaction disk.

No reagent in the reaction disk: The reagent probe misdetects the surface, aspirates air and dispenses into the reaction cuvette. Therefore, the reagent unit CPU fails to make any judgment. In this case, the sample probe cannot detect the surface when dispensing the sample into this reaction cuvette. Possible cause: Surface detection failure of the reagent probe insufficient reagent: The reagent probe aspirates less reagent than the set volume. As a result, the sample probe cannot detect the surface at the preset height. Possible cause: The reagent is prepared in the bottle, the reagent syringe is not fixed, leakage occurs in the tubing of the reagent probe, or there are bubbles in the reagent. Position correction parameter error of the sample probe: In case of such an error, the sample probe cannot reach the surface in the steps. Troubleshooting: Re-correct the sample probe position. Surface detection signal transmission failure: When the probe touches the surface and stops, the indicator of the surface detection board is on for about 2 seconds. The output signal of the surface detection board switches normally, but there is always a host alarm indicating that no surface is detected. Possible cause: The patch cord for detecting the sample surface is disconnected, or the connector is not well connected.

Surface detection failure of the sample probe

The sample probe cannot detect the surface at the reaction disk.

The sample probe misdetects the surface (In this case, there will be no alarm, but test results will become abnormal. On the reaction curve, you can see that no sample is added.)

Signal processing failure of the main control board: When the probe touches the surface, the indicator works normally. But there is always a host alarm indicating that no surface is detected. Ensure that the sample surface detection signal is transmitted to the relevant connector of the main control board. Possible cause: Main control board failure Surface detection signal failure: The indicator of the surface detection board is not on or always on when the sample probe touches the surface. Surface mis-detection at the sample disk: In this case, there will be no alarm, but the sample probe fails to aspirate the sample, and the test result and reaction curve become abnormal. Possible cause: Sample probe, surface detection board, surface detection patch cord. Surface mis-detection at the reaction disk: In this case, there will be no alarm, but there is residual sample on the sample probe tip, and drops on the table when the probe leaves the reaction disk. Possible cause: The sub-unit software is later than V1.7, or the sample probe is not in the center of the reaction cuvette.

Liquid Dropping From Probes Drips drop from the sample probe due to fluid tubing leakage. In this case, there will be liquid dropping onto the table widely, and there may be liquid dropping even when the sample probe is static.

Troubleshootin g for the liquid dropping from the reagent probe and sample probe. Drips drop from the sample probe due to surface detection failures. In this case, most liquid drop on the area between the reaction disk and the wash well.

Tubing leakage due to the abraded syringe piston Troubleshooting: Replace the syringe or the syringe piston

The reagent probe takes liquid from the reaction disk. The reagent probe did not detect the surface at the reaction disk, and dispenses the reagent at the corresponding height. If the reagent probe cannot touch the surface at the position for dispensing reagent, the last reagent drop will be taken out by the reagent probe. Possible cause: The probe arm is installed at a too high position; the position of the sample probe has not been corrected; the syringe is loose; there are bubbles in the reagent bottle.

The sample probe takes liquid from t he reaction disk. The sample probe detects the surface and stops immediately. Then it dispenses the sample at 1mm under the surface. If the reagent probe mis-detects the surface, the dispensed sample will fail to be added into the reagent, but taken at the probe tip and drops when the probe is moving. As a result, some test results become abnormal. Possible cause: There are bubbles in the reaction cuvette; the sample probe is not in the center of the reaction cuvette, and its position has not been corrected.

Drips taken from the reagent disk or sample disk and dropping from probes Such failures are usually followed by alarms indicating that no surface is detected at the reagent/sample disk. The reagent/sample probe does not aspirate reagent/sample, but the reagent/sample probe will stretch out to the bottom of the reagent bottle/sample tube due to surface detection failures. As a result, reagent/ sample liquid will be taken on the exterior of the probe and drop while the probe is moving.

Probe being bent Troubleshooting: Replace the probe.

Smudges on the sample probe absorb some liquid and drop it while the probe is moving. Troubleshooting: Cleaning the sample probe. Other failures Probe driving assemblies are not assembled well, resulting in probe jittering and liquid dropping in the vertical movements. Troubleshooting: Adjust or replace the probe driving assemblies.

Possible cause: Sample probe blocked, tubing leakage, syringe not fixed, valve not shut tightly.

All results are lower than normal results.

The reaction is not thorough. If the sample is not mixed uniformly with the reagent, the reaction will not be thorough, and the light cannot detect the changes of the absorbance. Possible cause: The mixing bar did not mix the reacting liquid.

All test results are abnormal

Some results are higher, and some are lower, with bad repeatability.

The volumes of dispensed sample are not the same. In this case, it can be seen from the reaction curve that the response is proportional to the volume of the sample. Possible cause: Tubing leakage, valve not shut tightly, or cuvette segments not cleaned well.

7.5.2 Some Results Being Abnormal Good repeatability Troubleshooting: Re-calibrate it.

Bad repeatability Observe the reaction curve, and find the possible causes. Some test results are abnormal. All test results are approaching to 0. Observe the reaction curve first. Possible cause: The lamp base of corresponding wavelength exceeds 65535; the photoelectric detection unit fails to detect the change of absorbance, reagent failure and optical fiber disconnection.

7.5.3 Several Results Being Abnormal Several test results are too low. In this case, observe the reaction curve first. Possible cause: Drips dropping from the sample probe Several test results are abnormal Several test results suddenly become too high. In this case, observe the reaction curve first. Possible cause: There are bubbles in the current cuvette; the mixing bar knocks the cuvettes.

Service Flow

7.9.2 Feeder Failure

The trolley moves backward to the end, but does not move forward. Possible causes:

Feeder failure symptom

1. The cuvette-taking limit signal has not been detected. 2. The belt is too tight, so the motor cannot run. Troubleshooting: 1. Check whether the voltage is 0 when the cuvette-taking limit optical coupler is blocked. 2. Adjust the position of the motor to loosen the belt.

The trolley moves forward and stops before compacting the cuvette segment

1. The moving resistance is too large, so the trolley fails to compact the cuvette segment, but the pressure transducer has been blocked. 2. The sliding block falls off, resulting in large friction. 3. The motor cannot work normally. 4. The belt is too tight. Troubleshooting: 1. Clean the guiding axis of the trolley. 2. Replace the sliding block assembly. 3. Replace the motor. 4. Loosen the belt.

The trolley keeps moving backward and forward

1. The no-cuvette transducer has not been pressed completely, so the system deems that the cuvette compartment is empty, and the trolley moves back for cuvette segments. Troubleshooting: 1. Adjust the position of the no-cuvette transducer. 2. Replace the feeder assemblies.

7-12

Service Flow

7.9.3 Manipulator Failure

Manipulator verticalmovement error: Cannot reach/leave the initial position.

The signal of the vertical optical coupler has not been detected after the motor runs for specified steps. Possible causes: 1. The resistance of the lead screw is too large (frequently). 2. The optical couplers for the vertical initial position cannot work (scarcely). 3. The vertical motor of the manipulator cannot work (scarcely). 4. The optical coupler connector is not connected well (infrequently). 5. The power driving board cannot work (infrequently). 6. The main control board cannot work (scarcely).

Troubleshooting: 1. Lubricate the lead screw after cleaning it. 2. Replace relevant assemblies.

The upper hand of the manipulator cannot close/open. Direct cause: The finger signal has not been detected after the electromagnet of the manipulator is switched on.

1. The snap ring of the manipulator is not flexible (infrequently). 2. The coupler of the upper finger cannot work any more (scarcely). 3. The upper hand of the manipulator is not arranged well with the position of the feeder/reaction disk (frequently). 4. The coupler connector is not connected well (infrequently).

1. Adjust the positions of the upper hand and the feeder/ reaction disk. 2. Replace the manipulator (Its position must be adjusted).

1. The operator has added too many cuvette segments into the feeder (behind the trolley). When the trolley moves backward, the jaw is pressed back by the cuvette segments; when it moves forward again, the hand fails to open in time, so the jaw may press one side of the trolley only. As a result, the cuvette segment at the front fails to corporate with the upper hand of the manipulator well (frequently). 2. The lower hand of the manipulator fails to corporate with the reaction disk position well (frequently). 3. The snap ring of the manipulator is not flexible (infrequently). 4. The lower hand coupler of the manipulator cannot work any more (scarcely).

1. Press the cuvette-taking key after adding cuvette segments into the feeder. 2. Adjust the positions of the lower hand and reaction disk. 3. Replace the manipulator (Its position must be adjusted)

1. The snap ring of the manipulator is not flexible (frequently). 2. The finger coupler of the manipulator cannot work any more (scarcely).

Troubleshooting: 1. Replace the manipulator (Its position must be adjusted).

Manipulator Failure

The lower hand of the manipulator cannot close/open. Direct cause: The finger signal has not been detected after the electromagnet of the manipulator is switched on.

The upper/lower hand of the manipulator accidentally closes/ opens. Direct cause: After the manipulator is switched on, the finger coupler signal is received, but the signal changes suddenly while the manipulator is moving.

7.10 Troubleshooting of ISE Unit (optional) When there is something wrong with the ISE unit, an error code will be displayed at the screen and saved in the log. The error code of the ISE unit has a format of 7 ASCII characters, the format of which is <1234567>. Each digit represents a certain error. 

Digit 1: Air in sample, Calibrant A, Calibrant B, Bubble Detector, mV range.



Digit 2: Sample/Calibrant B mV range.

7-13

Service Flow 

Digit 3: mV out of range for Calibrant A in Sample Cycle, or Calibrant B in Urine Cycle.



Digit 4: Noise in mV of Calibrant B in Calibration Cycle, or Sample mV during a Sample Cycle.



Digit 5: mV Noise in Calibrant A of the Calibration Cycle, or Sample Cycle, mV Noise in Calibrant B of the Urine Cycle.



Digit 6: mV Drift of calibrant A.



Digit 7: Slope of Sample value is out of range.

Each row represents where the error locates in. You can find all the seven numbers in the table below digit by digit and then know what is wrong with the ISE unit. 0 means no error. For example, when you see <0001000>, you only need to find where the “1” locates in the Digit 4 column and you will see it locates in the Na+ row. So you will know the + cause of this error is the noise in mV of Calibrant B or sample related to the Na electrode. Error
