3.4 Service Functions

The Service Functions mode provides a menu of service test functions to assist infailure diagnosis and identification. A logic flow chart is provided for reference ofthe sequences included in the Service Functions mode.

TEST ELECTRODES

This mode allows for the measurement and display of electrode voltages.Standard A, Standard B or an external sample can be measured to determineelectrode performance and provide measurement data useful in locating electrodecalibration faults. Each electrode parameter will be displayed and the electrodevoltage associated with the sample type selected can be observed.

Example Displays:

Std. A: Na=1582 Std. B: Na=237K= 654 Cl=-904 K=-988 Cl=647

Ext: Na=1321 K=-598 Cl= -127

TEST SAMPLE SENSOR

In this mode, the sample sensor output is displayed which is useful for electricaladjustment or for troubleshooting sample sensor faults. A dry sample sensor shoulddisplay a value of 100 with a range of 80 to 120. After verifying a dry sensor,aspiration of a clear fluid (i.e., water) should increase the displayed value by at least40 units.

Example Display:

For the 9120, 30, 40 and 80 analyzers, the front door can be removed by movingthe analyzer to the edge of a work surface so the analyzer door, when opened, willextend past the edge of the work surface. With one hand, hold the analyzer doornear the right side hinge pin and, with the other hand, gently apply pressure to themiddle rear area of the door. This will allow the right hinge pin to clear the retaininghole in the main chassis. The door can then be removed from the analyzer.The 9181 front panel can be removed by tilting it slightly away from the analyzerand lifting it straight up. The plastic window can also be replaced in the field bygently pressing from the rear of the window and snapping the plastic window outtoward the front of the analyzer door. The door magnets cannot be replaced in thefield as they are glued in place with conductive adhesive.

4.1.2 Needle Unit Assembly

Both sample needle and fill port are designed for easy replacement by the user.To remove the fill port assembly for replacement, pull the fill port holder towardsthe front for easy access. Then, press the two plastic tabs on the fill port to allowremoval of the fill port from the fill port holder. The sample needle can also beremoved and is supplied as a one-piece assembly including the intake tubing.To remove the sample needle, grasp the needle near the white holder block and pullup to unsnap the sample needle from its position. To replace the assembly, align areplacement sample needle and press the replacement assembly into place.

Three screws located on the left side of the assembly hold the needle unit assemblyin place. To access the two rear screws, turn power off and remove the rear panel.The rear panel can be moved away from the unit for easier access by unplugging thewire harness from the power supply. The SBC board can now be removed byremoving the screws which secure the SBC board and disconnecting the cables onthe SBC board. Disconnect the connector to the lamp board which supplies theDoor Open signal. The two rear screws which secure the needle unit can now beremoved using an Allen wrench. Then, remove the front securing screw, the sampleintake tubing and the reagent supply tubing (red tag) from the fill port. The needleunit can now be removed from the front of the analyzer for replacement. Referencethe Illustrated Parts diagram in Section 8 for a detailed parts diagram of the needleunit.

Replacement of the roller assembly of the peristaltic pump can be accomplishedby removing the pump tubing and firmly pulling the roller assembly toward thefront. To replace the roller assembly, align the roller and the flat on the motorshaft and press the replacement roller into position.

To remove the motor, first remove the rear panel assembly and SBC Board asdescribed in Sections 4.1.7 and 4.1.8. Now, the electrical connector on thelamp board can be accessed to unplug the motor connector. The motor cannow be removed by removing four screws located on the front of the housingnear the peristaltic pump.

4.1.5 Solenoid Assembly

Removal of each solenoid is identical. Each solenoid valve has a removablepressure piece which is held in place by a solenoid cap. To remove the pres-sure piece, locate the arrow on the solenoid cap and remove the solenoid capby sliding it off the solenoid shaft in the direction of the arrow. This exposes thepressure piece which can now be removed from the solenoid shaft. To replacepressure piece and cap, energize the solenoid as described in Section 3.2 (TestValves). This extends the solenoid shaft to the outermost position for ease inreplacing pressure piece and cap. Removal of the pressure piece and cap isrequired prior to removing the solenoid and allows for easier replacement of thetubing under each solenoid.

50

To remove the solenoid assembly, the rear panel and the SBC Board described inSection 4.1.8 must be removed first. Each solenoid has an electrical connection tothe lamp board which must be unplugged prior to removal of the solenoid. At thispoint, remove the two screws on the front panel to remove the solenoid assembly.

4.1.6 Printer Assembly

The printer assembly is designed to allow for easy removal by the user which can beaccomplished without removal of the electrical power to the analyzer. Slide thepaper tray forward to allow access to the printer, tear the paper roll and completelyremove it together with the paper tray. Slide fingers under the printer assembly andpull the printer forward. This will disengage the printer from the interconnector andenable removal of the assembly from the front of the analyzer. Removal of theprinter should be performed for replacement and for removal of a paper jam.To replace the printer, locate the printer slide and insert the printer assembly. Pressfirmly into place to ensure electrical connection of the printer.

Note: Never attempt to dislodge paper from the printer with a paper clip orsimilar object to avoid damage to the print head or printer platen.

4.1.7 Rear Panel Assembly

To remove the rear panel assembly, ensure that the power cord has been discon-nected. Remove the four corner screws to expose the rear panel. The powersupply module located on the rear panel assembly can now be removed by remov-ing the three screws securing the circuit board and by disconnecting the wiringinterconnections. The main power receptacle can also be replaced by removing thetwo screws holding this assembly.

4.1.8 SBC Board

After the rear panel (Section 4.1.7) has been removed, the SBC Board is acces-sible for removal. This circuit board can be removed by removing the sevenscrews securing the board to the housing and by disconnecting electrical connectorsfrom the power supply module, display board and lamp board.The electrode push pins can now be replaced by simply pulling the connecting pinfrom its socket. When installing the board, make sure to place the plastic washersunder the screw heads.

51

52

4.2 Fluidic Module

4.2.1 Standard A

Standard A is drawn to the electrode module by vacuum provided by the peristalticpump. When Standard A is to be aspirated into the electrode module, solenoidvalve A is opened and solenoid valves B, V and R are closed. Standard A is thendrawn from the ISE SnapPakTM, to the fill port, through the sample needle and issensed by the sample sensor. At this point, solenoid valve V is opened and sole-noid valve A is closed as the peristaltic pump continues to pump Standard A intothe electrode module. As the trailing edge of the Standard A sample is sensed bythe sample sensor, the peristaltic pump stops. During the time Standard A isaspirated into the electrode module, the reference housing is pressurized due to theperistaltic pump providing pressure to the reference solution line and solenoid valveR being closed. An amount of reference solution is forced out through the referencejunction to provide contact to the sample.

4.2.2 Standard B/C

The process for Standard B/C is identical to that of Standard A with the exceptionof the operation of solenoid valves B and C. These solenoid valves are operated inreverse order of Standard A aspiration.

4.2.3 Reference Solution

The reference housing is filled automatically using the second winding of theperistaltic pump and solenoid valve R. The reference solution connector allows forthe reference housing tubing to be plugged into the reference solution circuit. As theperistaltic pump aspirates reference solution, solenoid valve R is opened to allowexcess solution to be pumped into the reference return line of the ISE SnapPakTM.

4.2.4 Waste Liquids

Calibration standard and sample waste are pumped out of the left side of theelectrode module (green-banded tubing) through the peristaltic pump to the wasteline of the ISE SnapPakTM. An internal one-way valve is incorporated into thewaste line of each ISE SnapPakTM to prevent any waste products from leakingout of the ISE SnapPakTM.

53

4.2.5 Main Tube Set

The main tube set is supplied as a pre-cut tubing harness with the fluidic inter-connections preassembled. Replacement of the tube set should be performedannually. For removal of the tubing, first remove the ISE SnapPakTM from thereagent compartment. This will allow access for removal of the white TPRblock which is the main interconnection between the ISE SnapPakTM and thetubing. This block can be removed by grasping the front surface and pullingforward. Next, remove tubing from each solenoid valve. Follow the procedureoutlined in Section 4.1.5 for disassembly of the solenoid valves to enable fluidictubing to be easily removed at each solenoid. Pull the two pump windings at theperistaltic pump tube set off the pump roller and remove the white referencesolution tube connector. Remove the white TPR reference solution block bygrasping the front of the block and pulling forward. The three tube connectionsare labeled with green, blue and red tags. All remaining tubes can now beremoved and the entire tubing harness can be discarded.

Fit the replacement tubing harness and assemble in reverse order as disassem-bly. Reference the Tube Diagram on the next page for correct tube locations.

4.3 Electronics

4.3.1 ISE SBC Card

Power Circuits

Power is supplied to this circuit board through connector JP3 from the powersupply assembly. Test points are provided to measure supply voltages, and lightemitting diodes D1 through D5 are turned on to indicate each supply voltagepresent on the card. Since each LED is connected in series after the fuse, a blownfuse results in the respective LED turned off.

Four additional voltage regulator circuits are mounted on the ISE SBC II Card. ICU2 and IC U3 provide -8 VDC and +8 VDC (9180/9181: -5 VDC and +5 VDC)and are used to provide the supply voltages for the analog circuitry. IC U1 devel-ops the supply voltage used to operate the peristaltic pump and provide either +10VDC or +22 VDC. The +22 VDC is supplied only for the FAST speed and +10VDC is used for all other pump speeds. Signal FAST/SLOW determines whichsupply voltage is selected.

U5 switches the voltage between 22VDC and 12.5 VDC which supplies thesolenoids. When a solenoid is turned on, the voltage switches to 22VDC for 0.5sec, then it returns to 12.5 VDC.

The circuit which includes Q7 and R5 provides necessary switching for the measur-ing chamber illuminator LED’s.

The following list identifies the test points, fuses and LED’s for each respective DCsupply voltage:

57

Valve Drivers

The solenoids are activated by transistors Q9 - Q13. To open the solenoid, a0.5-second pulse of 22 volts is applied, then the voltage drops down to 12.5volts to hold the solenoid open.

Pump Motor Driver/Cover Sensor

The pump driver circuit IC U9 and IC U10 provide the drive and control forthe peristaltic pump. Signals PUMPEN, Pump Enable and PUMPSTEP, PumpStep Pulses enable IC U10 to provide the necessary control to driver IC U9which supplies pump drive signals PHASE A through PHASE D to controlperistaltic pump operation.

IC U11 operates with signal DCLOSED from the sample door light gate toprovide signal DOOR which detects the status of the sample door (open orclosed).

Input Amplifiers

IC U13, U14 and U15 (9180/9181: U13 only) provide high to low inputimpedance matching for each Electrode input. Offset generator IC U12D andamplifiers IC U12A, U12B and U12C provide the necessary gain and offset foreach electrode channel. TP9, TP10 and TP11 provide test points for the Na+,K+ and Cl-/Ca++/Li channels respectively.

Temperature Sensor

This is an optional circuit which is used in the 9140, 9180 and 9181.The circuit creates a temperature-dependent voltage which is converted bysoftware to degrees C. R54 can be adjusted for correct temperature setting.

Analog Channel Selector and A/D Converter

Analog inputs from the input amplifiers are selected via signals ADSEL0 throughADSEL2 and are multiplexed by IC U19. This multiplexed signal is then fed tothe A/D Converter IC U20. IC U21 supplies the necessary reference voltage(2500mV) for the A/D Converter and can be measured at TP14.

58

Microprocessor

Microprocessor IC U31, EPROM IC U25 (9180/9181: U40) and MOSTEK RealTime Clock/RAM IC U22 form the components of the central processing system.IC U23 Address Demultiplexer, IC U24 Programmable Array Logic (PAL) and ICU28 provide serial data buses (9180/9181: U23, U24 and U28 not present). ICU34 through IC U38 convert serial data to parallel data and provide printer data,display data, solenoid valve control and peristaltic pump control. This fashion ofserial to parallel data conversion is used to prevent analyzer lock-up by peripheraldevices. The RS232 serial interface is a direct input/output from the microproces-sor utilizing interface driver and receiver U29 and U30.

SnapPak Sensor (9180/9181 only)

Optical detector ISO1 provides a signal indicating if the ISE SnapPak™ is in place.This signal is fed to U41 which converts the light gate input to a digital logic outputindicating SnapPak position (IN or OUT).

4.3.2 Lamp Board

The lamp board contains the LED array used to illuminate the measuring chamberand the interconnectors used for all solenoids, the peristaltic pump, door sensor andsample turntable (9181 only). A ribbon cable from the SBC Board supplies theelectrical connection for each signal through connector JP6.

4.3.3 Display Board

The display board contains the LCD display, sample sensor connector and theYES and NO switches used for operation of the analyzer. Power and signalinterconnection is accomplished via a ribbon cable from the SBC board throughJP2 on the display board.

5.2 Error Messages and Troubleshooting

STATUS: NOT CALIBRATED

This message is only displayed when a calibration has been interrupted bypressing NO or opening the sample door. Perform a calibration to return to theREADY Mode.

STANDARD A NOT DETECTED

This message is displayed when the sample sensor is unable to properly detectthe Standard A solution in a programmed time period. As the analyzer draws asample of Standard A, the leading edge of the solution is detected by thesample sensor. The sample sensor must also detect a continuous flow ofStandard A Solution into the sample chamber, lasting several seconds, withoutencountering air bubbles or air. After several seconds, the trailing edge of theStandard A sample is sensed, the peristaltic pump stops and measurementoccurs.

Possible causes and remedies:

• Check for air leaks preventing the Standard from being drawn into thechamber. Ensure that all O-rings are in place. There must be acontinuous draw of standard solution, free of air bubbles. Check solenoid V for proper sealing of the vent line. Check fill port to ensure the absence of air leaks.

• Check for clots or crystals formed in the Standard A tubing orelectrode chamber.

• Ensure that the sample sensor is plugged in securely and performSample Sensor Test to ensure sensor is operating correctly. Clean,adjust or replace sample sensor to correct sample sensor operation.

• Replace peristaltic pump tube set to ensure proper sample aspiration.

• Check the fluid remaining in the ISE SnapPakTM. If less than 5%remains, replace the ISE SnapPakTM.

61

STANDARD B NOT DETECTEDSTANDARD C NOT DETECTED (9180/9181 only)

The system for drawing Standard B or C is like that of Standard A. If Standard Ais drawn properly and Standard B or C is not detected, check Standard B tubingfor crystallization. Perform checks for Standard A detection problems to correct.During the calibration sequence, Standard B or C is drawn into the measuringchamber prior to Standard A, therefore check if Standard A calibrant can beproperly detected to isolate possible fluidic faults. If neither Standard A, B nor Care detected check for air leaks or blockages within the fluidic path.

CHECK SAMPLE SENSOR

The sample sensor must provide a reading of 80 - 120 when air is detected.Perform Test Sample Sensor to observe sample sensor response. When clear fluid(e.g. water) is aspirated, the sample sensor display must indicate an increase of of atleast 40 units. For blood samples (not transparent), the reading should decrease byat least 40 units. The sample sensor is calibrated with air during each calibration.Perform a calibration to remove the error message after troubleshooting.


• Clean sample sensor using Daily Cleaning procedure.

• Check for correct drying of measuring chamber during the wash cycle.

• Replace peristaltic pump tube set.

• Test and adjust sample sensor to correct adjustment.

• Replace sample sensor assembly.

62

CHECK REFERENCE HOUSING

At the beginning of a calibration, pressure is formed in the reference housingwhile the R valve is closed and the V valve is open. After Standard A isdetected in the sample chamber, the back pressure formed in the referencehousing causes the Standard A solution to move back toward the samplesensor. When the standard A solution is detected by the sample sensor, the Rvalve is opened to release the pressure. If the sample sensor does not detectstandard A as it moves back, CHECK REFERENCE HOUSING will bedisplayed.


• Check for clogged reference housing and clean per monthlymaintenance procedures.

• Check and ensure that reference tubing is securely connected at thetubing connector.

• Check for proper filling of the reference housing and ensure thatreference solution reagent level allows complete filling of thereference housing.

• Check for bubble-free aspiration of Standard A.

6 Adjustments

The 9120, 30, 40, 80 and 81 Analyzers have been designed to require minimalelectronic adjustment. The sample sensor circuit may require adjustment following achange of the sample sensor or during routine troubleshooting. The temperatureadjustment is active only for models 9140/9180/9181 and requires the temperatureadjustment test plug for correct calibration of the temperature circuit.

6.1 Sample Sensor Adjustment

Select TEST SAMPLE SENSOR in the SERVICE FUNCTIONS menuwhich will display the current sample sensor setting. Adjust R93 Sample SensorAdjust located at the top of the ISE SBC card to a value of 100. Press YES toturn on peristaltic pump and ensure displayed value remains constant.

Raise sample door and aspirate clear fluid (e.g. water). Displayed reading shouldnow be 150 or greater.

Note: R93 can be accessed through the rear cover vent slot and is located atthe top center on the circuit card.

6.2 Temperature Adjustment (9140/9180/9181 only)

Select AMPLIFIER TEST in the SERVICE FUNCTIONS menu which willdisplay the current amplifier voltages. Press NO twice to display the temperaturevoltage and actual temperature display. Unplug the sample sensor and fit theTemperature Adjustment Test Plug in place of the sample sensor plug. Adjust R54located on the SBC Board for a display of 3000mV. Unplug the TemperatureAdjustment Test Plug and fit the sample sensor connector to display the actualtemperature of the measuring chamber.

Due to the elevated temperature inside the analyzer, it is normal for thedisplayed temperature to be several degrees C higher than the actual roomtemperature.

If no Temperature Adjustment Test Plug is available, place a quality thermometer(preferably mercury) next to the right side electrode holder. With the front dooropen, wait approx. 10 min. Then adjust the displayed temperature to match thereading on the thermometer.

9 Interface Specifications

9.1 Interface Information

The AVL 9120, 30, 40, 80 and 81 analyzers are equipped with a standardserial interface output. This interface output is intended to be used withstandard commercially available computer systems.

The data transmitted through the serial interface port employs the ASCII code.

The serial interface is terminated on the rear cover with a 9-pin male DB-9connector.

The signal levels are as follows:

- Binary 1 = -12V to -3V- Binary 0 = +3V to +12V

Two stop bits follow the eight data bits to complete the 10 bit word.

The baud rate is set at 9600 Baud fixed.

The maximal recommended cable length is 40 feet.

The pin assignment is as follows:

pin 1...sample ground...GNDpin 2...receive data....RxDpin 3...send data.......TxDpin 4...NCpin 5...signal ground...GNDpin 6...NCpin 7...RTSpin 8...CTSpin 9...NC

(NC=Not Connected)

108

Software

The patient sample data is sent at the end of each measurement, the calibra-tion report is sent at the end of each calibration.

The interface is always on, independent of the printer settings; the data isalways sent.

Note: The arrow up (e.g. out of normal range) is sent as HEX 18 (↑), thearrow down as HEX19 (↓) and the ° (degree) is sent as HEX1A (→).

9.3 Data Link Information (9180/9181 only)

The data link with the AVL Compact 2/3 blood gas analyzer allows tocombine ISE results with pH/blood gas results on one printout. If Ca++ isactivated on the 9180/9181, a pH-corrected Ca++ value will be calculatedand printed on the combined sample report.

For connection of the 9180/9181 analyzer to the Compact 2/3 analyzer, theoptional Interface Kit (BP5202) is required. To install the kit, first turnboth instruments off. Connect the interface filter provided in the kit to theRS232 port on the 9180/9181. Then connect one end of the cable to theinterface filter, the other end to the COM 2 port on the Compact 2/3. Onthe Compact 2/3, select 9180 under the COM2 interface options.See Compact 2/3 Operator's Manual for details.
