3.4 Service Functions
The Service Functions mode provides a menu of service test functions to assist in failure diagnosis and identification. A logic flow chart is provided for reference of the 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 determine electrode performance and provide measurement data useful in locating electrode calibration faults. Each electrode parameter will be displayed and the electrode voltage associated with the sample type selected can be observed.
Example Displays:
Std. A: Na=1582
K= 654 Cl=-904
Std. B: Na=237
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 electrical adjustment or for troubleshooting sample sensor faults. A dry sample sensor should display 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 least
40 units.
Example Display:

4 Description of Modules
4.1
Mechanical Assemblies
4.1.1 Front Door Assembly
For the 9120, 30, 40 and 80 analyzers, the front door can be removed by moving the analyzer to the edge of a work surface so the analyzer door, when opened, will extend past the edge of the work surface. With one hand, hold the analyzer door near the right side hinge pin and, with the other hand, gently apply pressure to the middle rear area of the door. This will allow the right hinge pin to clear the retaining hole 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 analyzer and lifting it straight up. The plastic window can also be replaced in the field by gently pressing from the rear of the window and snapping the plastic window out toward the front of the analyzer door. The door magnets cannot be replaced in the field 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 towards the front for easy access. Then, press the two plastic tabs on the fill port to allow removal of the fill port from the fill port holder. The sample needle can also be removed 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 pull up to unsnap the sample needle from its position. To replace the assembly, align a replacement sample needle and press the replacement assembly into place.
Three screws located on the left side of the assembly hold the needle unit assembly in 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 the wire harness from the power supply. The SBC board can now be removed by removing the screws which secure the SBC board and disconnecting the cables on the SBC board. Disconnect the connector to the lamp board which supplies the
Door Open signal. The two rear screws which secure the needle unit can now be removed using an Allen wrench. Then, remove the front securing screw, the sample intake tubing and the reagent supply tubing (red tag) from the fill port. The needle unit can now be removed from the front of the analyzer for replacement. Reference the Illustrated Parts diagram in Section 8 for a detailed parts diagram of the needle unit.
4.1.3 Electrode Holder Assembly
To remove the electrode holder assembly from the analyzer, first unplug the sample intake tubing on the right side of the module, then the sample sensor cable, then remove the reference solution tubing connector and last, take out the waste tube (green tag) at the left side of the electrode holder. The electrode holder can now be removed by pressing the two plastic tabs (right and left side of the module) and sliding the module forward. Press the plastic tabs again to release the second detent and completely remove the module from the analyzer.
The sample sensor and/or the left side electrode holder can be removed and replaced by removing the screws on the under side of this module. The Illustrated Parts List in Section 8 provides a detailed reference of the parts of this assembly.
4.1.4 Peristaltic Pump Assembly
Replacement of the roller assembly of the peristaltic pump can be accomplished by removing the pump tubing and firmly pulling the roller assembly toward the front. To replace the roller assembly, align the roller and the flat on the motor shaft and press the replacement roller into position.
To remove the motor, first remove the rear panel assembly and SBC Board as described in Sections 4.1.7 and 4.1.8. Now, the electrical connector on the lamp board can be accessed to unplug the motor connector. The motor can now be removed by removing four screws located on the front of the housing near the peristaltic pump.
4.1.5 Solenoid Assembly
Removal of each solenoid is identical. Each solenoid valve has a removable pressure piece which is held in place by a solenoid cap. To remove the pressure piece, locate the arrow on the solenoid cap and remove the solenoid cap by sliding it off the solenoid shaft in the direction of the arrow. This exposes the pressure piece which can now be removed from the solenoid shaft. To replace pressure piece and cap, energize the solenoid as described in Section 3.2 (Test
Valves). This extends the solenoid shaft to the outermost position for ease in replacing pressure piece and cap. Removal of the pressure piece and cap is required prior to removing the solenoid and allows for easier replacement of the tubing under each solenoid.
49
50
To remove the solenoid assembly, the rear panel and the SBC Board described in
Section 4.1.8 must be removed first. Each solenoid has an electrical connection to the lamp board which must be unplugged prior to removal of the solenoid. At this point, 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 be accomplished without removal of the electrical power to the analyzer. Slide the paper tray forward to allow access to the printer, tear the paper roll and completely remove it together with the paper tray. Slide fingers under the printer assembly and pull the printer forward. This will disengage the printer from the interconnector and enable removal of the assembly from the front of the analyzer. Removal of the printer 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. Press firmly into place to ensure electrical connection of the printer.
Note: Never attempt to dislodge paper from the printer with a paper clip or similar 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 disconnected. Remove the four corner screws to expose the rear panel. The power supply module located on the rear panel assembly can now be removed by removing the three screws securing the circuit board and by disconnecting the wiring interconnections. The main power receptacle can also be replaced by removing the two screws holding this assembly.
4.1.8 SBC Board
After the rear panel (Section 4.1.7) has been removed, the SBC Board is accessible for removal. This circuit board can be removed by removing the seven screws securing the board to the housing and by disconnecting electrical connectors from the power supply module, display board and lamp board.
The electrode push pins can now be replaced by simply pulling the connecting pin from its socket. When installing the board, make sure to place the plastic washers under the screw heads.
4.1.9 Lamp Board
The rear panel and SBC board must be removed to gain access to the lamp board. Remove one screw and washer which hold the board in place and remove the electrical connectors to remove this board.
4.1.10 Display Board
The rear panel and SBC board must be removed to gain access to the display board. Remove three screws and 50 degree spacers and unplug the sample sensor cable from the front and the ribbon cable to the SBC board to remove the display board.
51
52
4.2 Fluidic Module
4.2.1 Standard A
Standard A is drawn to the electrode module by vacuum provided by the peristaltic pump. When Standard A is to be aspirated into the electrode module, solenoid valve A is opened and solenoid valves B, V and R are closed. Standard A is then drawn from the ISE SnapPak TM , to the fill port, through the sample needle and is sensed by the sample sensor. At this point, solenoid valve V is opened and solenoid valve A is closed as the peristaltic pump continues to pump Standard A into the electrode module. As the trailing edge of the Standard A sample is sensed by the sample sensor, the peristaltic pump stops. During the time Standard A is aspirated into the electrode module, the reference housing is pressurized due to the peristaltic pump providing pressure to the reference solution line and solenoid valve
R being closed. An amount of reference solution is forced out through the reference junction 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 exception of the operation of solenoid valves B and C. These solenoid valves are operated in reverse order of Standard A aspiration.
4.2.3 Reference Solution
The reference housing is filled automatically using the second winding of the peristaltic pump and solenoid valve R. The reference solution connector allows for the reference housing tubing to be plugged into the reference solution circuit. As the peristaltic pump aspirates reference solution, solenoid valve R is opened to allow excess solution to be pumped into the reference return line of the
ISE SnapPak TM
.
4.2.4 Waste Liquids
Calibration standard and sample waste are pumped out of the left side of the electrode module (green-banded tubing) through the peristaltic pump to the waste line of the
ISE SnapPak TM
. An internal one-way valve is incorporated into the waste line of each
ISE SnapPak TM
to prevent any waste products from leaking out of the
ISE SnapPak TM
.
4.2.5 Main Tube Set
The main tube set is supplied as a pre-cut tubing harness with the fluidic interconnections preassembled. Replacement of the tube set should be performed annually. For removal of the tubing, first remove the ISE SnapPak
TM
from the reagent compartment. This will allow access for removal of the white TPR block which is the main interconnection between the ISE SnapPak TM and the tubing. This block can be removed by grasping the front surface and pulling forward. Next, remove tubing from each solenoid valve. Follow the procedure outlined in Section 4.1.5 for disassembly of the solenoid valves to enable fluidic tubing to be easily removed at each solenoid. Pull the two pump windings at the peristaltic pump tube set off the pump roller and remove the white reference solution tube connector. Remove the white TPR reference solution block by grasping the front of the block and pulling forward. The three tube connections are labeled with green, blue and red tags. All remaining tubes can now be removed and the entire tubing harness can be discarded.
Fit the replacement tubing harness and assemble in reverse order as disassembly. 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 power supply assembly. Test points are provided to measure supply voltages, and light emitting diodes D1 through D5 are turned on to indicate each supply voltage present on the card. Since each LED is connected in series after the fuse, a blown fuse results in the respective LED turned off.
Four additional voltage regulator circuits are mounted on the ISE SBC II Card. IC
U2 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 develops the supply voltage used to operate the peristaltic pump and provide either +10
VDC or +22 VDC. The +22 VDC is supplied only for the FAST speed and +10
VDC is used for all other pump speeds. Signal FAST/SLOW determines which supply voltage is selected.
U5 switches the voltage between 22VDC and 12.5 VDC which supplies the solenoids. When a solenoid is turned on, the voltage switches to 22VDC for 0.5
sec, then it returns to 12.5 VDC.
The circuit which includes Q7 and R5 provides necessary switching for the measuring chamber illuminator LED’s.
The following list identifies the test points, fuses and LED’s for each respective DC supply voltage:

Valve Drivers
The solenoids are activated by transistors Q9 - Q13. To open the solenoid, a
0.5-second pulse of 22 volts is applied, then the voltage drops down to 12.5
volts to hold the solenoid open.
Pump Motor Driver/Cover Sensor
The pump driver circuit IC U9 and IC U10 provide the drive and control for the peristaltic pump. Signals PUMPEN, Pump Enable and PUMPSTEP, Pump
Step Pulses enable IC U10 to provide the necessary control to driver IC U9 which supplies pump drive signals PHASE A through PHASE D to control peristaltic pump operation.
IC U11 operates with signal DCLOSED from the sample door light gate to provide signal DOOR which detects the status of the sample door (open or closed).
Input Amplifiers
IC U13, U14 and U15 (9180/9181: U13 only) provide high to low input impedance matching for each Electrode input. Offset generator IC U12D and amplifiers IC U12A, U12B and U12C provide the necessary gain and offset for each 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 by software 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 through
ADSEL2 and are multiplexed by IC U19. This multiplexed signal is then fed to the A/D Converter IC U20. IC U21 supplies the necessary reference voltage
(2500mV) for the A/D Converter and can be measured at TP14.
57
58
Microprocessor
Microprocessor IC U31, EPROM IC U25 (9180/9181: U40) and MOSTEK Real
Time Clock/RAM IC U22 form the components of the central processing system.
IC U23 Address Demultiplexer, IC U24 Programmable Array Logic (PAL) and IC
U28 provide serial data buses (9180/9181: U23, U24 and U28 not present). IC
U34 through IC U38 convert serial data to parallel data and provide printer data, display data, solenoid valve control and peristaltic pump control. This fashion of serial to parallel data conversion is used to prevent analyzer lock-up by peripheral devices. The RS232 serial interface is a direct input/output from the microprocessor 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 output indicating SnapPak position (IN or OUT).
4.3.2 Lamp Board
The lamp board contains the LED array used to illuminate the measuring chamber and the interconnectors used for all solenoids, the peristaltic pump, door sensor and sample turntable (9181 only). A ribbon cable from the SBC Board supplies the electrical connection for each signal through connector JP6.
4.3.3 Display Board
The display board contains the LCD display, sample sensor connector and the
YES and NO switches used for operation of the analyzer. Power and signal interconnection is accomplished via a ribbon cable from the SBC board through
JP2 on the display board.
Display boards utilized in the 9181 analyzer also contain circuitry for both the needle mechanism motor control and position sensor. The autosampler "Table
Present" signal is also buffered through U1 on this board.

5.2 Error Messages and Troubleshooting
STATUS: NOT CALIBRATED
This message is only displayed when a calibration has been interrupted by pressing NO or opening the sample door. Perform a calibration to return to the
READY Mode.
•
•
•
•
STANDARD A NOT DETECTED
This message is displayed when the sample sensor is unable to properly detect the Standard A solution in a programmed time period. As the analyzer draws a sample of Standard A, the leading edge of the solution is detected by the sample sensor. The sample sensor must also detect a continuous flow of
Standard A Solution into the sample chamber, lasting several seconds, without encountering air bubbles or air. After several seconds, the trailing edge of the
Standard A sample is sensed, the peristaltic pump stops and measurement occurs.
•
Possible causes and remedies:
Check for air leaks preventing the Standard from being drawn into the chamber. Ensure that all O-rings are in place. There must be a continuous 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 or electrode chamber.
Ensure that the sample sensor is plugged in securely and perform
Sample 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 SnapPak TM . If less than 5% remains, replace the
ISE SnapPak TM
.
STANDARD B NOT DETECTED
STANDARD C NOT DETECTED
(9180/9181 only)
The system for drawing Standard B or C is like that of Standard A. If Standard A is drawn properly and Standard B or C is not detected, check Standard B tubing for crystallization. Perform checks for Standard A detection problems to correct.
During the calibration sequence, Standard B or C is drawn into the measuring chamber prior to Standard A, therefore check if Standard A calibrant can be properly detected to isolate possible fluidic faults. If neither Standard A, B nor C are 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 at least 40 units. For blood samples (not transparent), the reading should decrease by at least 40 units. The sample sensor is calibrated with air during each calibration.
Perform a calibration to remove the error message after troubleshooting.
Possible causes and remedies:
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.

•
•
•
•
CHECK REFERENCE HOUSING
At the beginning of a calibration, pressure is formed in the reference housing while the R valve is closed and the V valve is open. After Standard A is detected in the sample chamber, the back pressure formed in the reference housing causes the Standard A solution to move back toward the sample sensor. When the standard A solution is detected by the sample sensor, the R valve is opened to release the pressure. If the sample sensor does not detect standard A as it moves back, CHECK REFERENCE HOUSING will be displayed.
Possible causes and remedies:
Check for clogged reference housing and clean per monthly maintenance procedures.
Check and ensure that reference tubing is securely connected at the tubing connector.
Check for proper filling of the reference housing and ensure that reference solution reagent level allows complete filling of the reference housing.
Check for bubble-free aspiration of Standard A.

6 Adjustments
The 9120, 30, 40, 80 and 81 Analyzers have been designed to require minimal electronic adjustment. The sample sensor circuit may require adjustment following a change of the sample sensor or during routine troubleshooting. The temperature adjustment is active only for models 9140/9180/9181 and requires the temperature adjustment test plug for correct calibration of the temperature circuit.
6.1 Sample Sensor Adjustment
Select TEST SAMPLE SENSOR in the SERVICE FUNCTIONS menu which will display the current sample sensor setting. Adjust R93 Sample Sensor
Adjust located at the top of the ISE SBC card to a value of 100. Press YES to turn on peristaltic pump and ensure displayed value remains constant.
Raise sample door and aspirate clear fluid (e.g. water). Displayed reading should now be 150 or greater.
Note: R93 can be accessed through the rear cover vent slot and is located at the top center on the circuit card.
6.2 Temperature Adjustment (9140/9180/9181 only)
Select AMPLIFIER TEST in the SERVICE FUNCTIONS menu which will display the current amplifier voltages. Press NO twice to display the temperature voltage and actual temperature display. Unplug the sample sensor and fit the
Temperature Adjustment Test Plug in place of the sample sensor plug. Adjust R54 located on the SBC Board for a display of 3000mV. Unplug the Temperature
Adjustment Test Plug and fit the sample sensor connector to display the actual temperature of the measuring chamber.
Due to the elevated temperature inside the analyzer, it is normal for the displayed temperature to be several degrees C higher than the actual room temperature.
If no Temperature Adjustment Test Plug is available, place a quality thermometer
(preferably mercury) next to the right side electrode holder. With the front door open, wait approx. 10 min. Then adjust the displayed temperature to match the reading on the thermometer.

9 Interface Specifications
9.1 Interface Information
The AVL 9120, 30, 40, 80 and 81 analyzers are equipped with a standard serial interface output. This interface output is intended to be used with standard 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-9 connector.
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...GND
pin 2...receive data....RxD
pin 3...send data.......TxD
pin 4...NC
pin 5...signal ground...GND
pin 6...NC
pin 7...RTS
pin 8...CTS
pin 9...NC
(NC=Not Connected)
107
108
Software
The patient sample data is sent at the end of each measurement, the calibration report is sent at the end of each calibration.
The interface is always on, independent of the printer settings; the data is always sent.
Note: The arrow up (e.g. out of normal range) is sent as HEX 18 (
↑
), the arrow 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 to combine ISE results with pH/blood gas results on one printout. If Ca ++ is activated on the 9180/9181, a pH-corrected Ca
++
value will be calculated and printed on the combined sample report.
For connection of the 9180/9181 analyzer to the Compact 2/3 analyzer, the optional Interface Kit (BP5202) is required. To install the kit, first turn both instruments off. Connect the interface filter provided in the kit to the
RS232 port on the 9180/9181. Then connect one end of the cable to the interface filter, the other end to the COM 2 port on the Compact 2/3. On the Compact 2/3, select 9180 under the COM2 interface options.
See Compact 2/3 Operator's Manual for details.
