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: DRY 80-120: 102 YES=Pump/No=Exit 42 External: 153 Pump: NO=OFF TEST SnapPak SENSOR (9180 and 9181 only) In this test, the SnapPak Sensor detects whether the ISE SnapPak™ is in place. "I" indicates that the ISE SnapPak™ is in place, "O" indicates that it is either not present or not completely seated. Example Display: SnapPak: I I = IN O = OUT TEST LANGUAGE SWITCH (9180 and 9181 only) This mode displays the language selected for display and printout. To change the selection, set the language switch (located behind printer) to the desired language. The display will indicate the language choice according to the switch setting. To activate a new language, turn the analyzer off and back on with the switch set to the desired language. Example Display: Lanugage Switch English TEST SAMPLE DOOR (except 9181) This test verifies the operation of the sample door light gate and its associated circuitry. The display indicates an “O” or “C” depending on the position of the door. Example Display: Sample Door: C C:Closed/O:Open 43 TEST PROBE (9181 only) This test verifies the operation of the sample probe motor, position sensor and associated circuitry. The "U" represents the output of the upper position sensor, the "L" represents the output of the lower position sensor. Example Display: U=0 L=1 Sample Position? TEST AUTOSAMPLER (9181 only) This test verifies the operation of the Autosampler turntable assembly. The display indicates the output of both the position and home sensors. Note: If the Autosampler is not plugged in or the TABLE PRESENT bit is not activated, this test will not appear under the SERVICE FUNCTIONS menu. Example Display: Home: 0 Pos = 1 TEST PUMP This test turns on the peristaltic pump at each of the four pump speeds. The display indicates for two seconds each pump speed while each pump speed is being tested. Observe that the peristaltic pump changes speed as is indicated on the display. 44 *** Pump Test *** Very Slow Speed *** Pump Test *** Slow Speed *** Pump Test *** Medium Speed *** Pump Test *** Fast Speed TEST PINCH VALVES This test turns on/off each solenoid valve as indicated and is useful to verify both electronic control and mechanical operation of each solenoid valve. TEST INTERFACE The Interface Test can be used to verify correct operation of the RS232C serial port. To operate this test, jumper pin 2 and pin 3 of the rear interface connector prior to invoking the test. During the interface test, the analyzer sends out a test string and checks if it is received within a set period of time. If correct operation is observed after completion of the test, INTERFACE OK will be displayed. TEST AMPLIFIER The Amplifier Test displays ground, reference and output voltage of each input amplifier. The values displayed for each electrode channel will be dependent on the electrode inputs and may vary. Display of the ground should read between -10mV and +10mV with the reference voltage reading between -2490mV and -2510mV. With all inputs open, the display should read +/- 4095 for each channel. On the 9140/ 9180/9181, an additional display indicating the temperature voltage and temperature in degrees C is available to verify the temperature adjustment. ENTER SERVICE CODE Service Codes are available and allow additional programming features. Following is a listing of the available Service Codes and functions: Set Reset Service Code Description ALL LLA (9181 only) This service code will enable the Ca++ value during automatic serum/blood measurement. Special precautions are necessary to obtain the correct Ca++ value due to sample exposure to room air. CDC Clears all Service Codes. 45 46 DEC CED Provides one additional digit of resolution for each measured parameter for blood and serum samples. QC and Standard samples are always displayed with high resolution. Urine samples are always displayed in low resolution. ECO OCE Allows the operator to run the instrument in the economy mode. The instrument will enter the STANDBY MODE. This occurs at the time of the next 2-point calibration when no samples have been analyzed since the last 2-point calibration. FIF Allows printing of electrode voltages during printout of measurements and calibrations. (not available for 9140) IFI LEM MEL (9180/9181 only) This service code will print the last 20 error messages with the date and time of occurrence. MGL LGM This service code is available only in the model 9140/ 9180/9181 analyzer and enables Ca++ values to be displayed in mg/dL. The normal mode displays values in mmol/L. QC and Standard results are always displayed in mmol/L. NOB BON (9180 /9181only) This service code disables the beep. QCC CCQ When this code is enabled, QC values will be reported in direct ISE measurement instead of flame-equivalent values. In this mode, correlation factors are NOT applied to the measured values. SFC (9180/9181 only) This code allows the input of a percentage for the ISE SnapPakTM counter. SLC CLS (9180/9181 only) When this code is set, the current setting of the leasing counter, which cannot be reset by the operator, is printed on the calibration report. SSC CSS (9181 only) This code toggles needle height to accommodate smaller sample cups. In the default setting, the analyzer works with 2.0 mL cups. To select 0.25 mL sample cups, SSC has to be activated. To return to the default setting, CSS has to be activated.

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. 48 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 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. 50 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 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 SnapPakTM, 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 SnapPakTM. 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 SnapPakTM. An internal one-way valve is incorporated into the waste line of each ISE SnapPakTM to prevent any waste products from leaking out of the ISE SnapPakTM. 52 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 SnapPakTM from the reagent compartment. This will allow access for removal of the white TPR block which is the main interconnection between the ISE SnapPakTM 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. 53 54 FLUID PACK A B (NOT USED) C WASTE REF REF.

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: 56 Test Point Voltage Fuse Rating TP1 TP2 TP3 TP4 TP5 TP6 TP7 TP8 TP9 TP10 TP11 TP12 TP13 TP14 TP15 TP16 +24 VDC F3 +5 VDC F1/F2 -12 VDC F4 +12 VDC F5 Ground -8 VDC (9180/9181: -5 VDC) +22/12 VDC +8 VDC (9180/9181: +5 VDC) Na+ Channel K+ Channel Ca++/Cl- Channel (Li+ 9180/9181 only) Temperature +10.000 V Ref. Voltage -2.500 VRef. Voltage Sample Sensor +22/12.5VDC LED D3 D1/D2 D4 D5 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 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. 58 5 Maintenance and Troubleshooting Maintenance procedures for the 9120, 30, 40, 80, 81 Analyzers require minimal time by the operator to perform. The procedures outlined below should be performed by the schedule indicated. Detailed instructions for these procedures can be found in the Operator's Manual describing the correct method to perform routine analyzer maintenance. 5.1 Maintenance Daily Maintenance - Perform cleaning cycle. - Perform conditioning cycle. Weekly Maintenance - Clean sample probe and fill port. - Clean analyzer surfaces. Monthly Maintenance - Clean reference electrode housing. Six Month Maintenance - Replace peristaltic pump tubing. Annual Preventive Maintenance - Replace complete tubing set. - Replace peristaltic pump tubing. - Replace fill port assembly. - Replace sample probe. - Replace sample sensor Quad-ring. - Check sample sensor voltage. - Check sample temperature (9140/80/81 only). 59 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: 60 • 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 SnapPakTM. If less than 5% remains, replace the ISE SnapPakTM. 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. 61 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. PLEASE CLOSE SAMPLE DOOR (except 9181) This message occurs and prints NO SAMPLE on the print-out, when either of two conditions exists. 1. Sample door is not closed within 20 seconds after samples are in place. 2. Sample door has been opened and no sample is detected within 20 seconds. Possible causes and remedies: 62 • Close sample door within the time allowed. • Check needle mechanism light gate. • Check whether sample sensor is plugged in. NO SAMPLE This message is displayed when any of the following conditions occur: 1. During sampling, either a bubble in the sample is detected or thesample size is smaller than the minimum sample required. 2. The sample door is opened and no sample is fed into the analyzer. 3. Sample door is not closed within 20 seconds after sample is detected. Possible causes and remedies: • Check whether the sample sensor is plugged in and perform TEST SAMPLE SENSOR to verify that it operates correctly. • Check sample draw and look for clots or leaks in the sampling system. CLEANING FLUID NOT DETECTED When the cleaning cycle has been initiated, the analyzer checks for proper aspiration of the cleaning solution using the sample sensor. If solution is not detected in the proper time, above error message will be displayed. Possible causes and remedies: • Ensure that a sufficient volume of cleaning solution is presented for aspiration and no air bubbles are present as solution is aspirated. • Check to ensure that the solution is being aspirated through the sampling mechanism correctly. The sample path must be free of leaks or clots. • Verify that sample sensor is properly plugged in and perform the SAMPLE SENSOR TEST to verify the correct operation of the sample sensor. • Check pump tubing and replace as necessary to ensure a correct pump rate. 63 CONDITIONING FLUID NOT DETECTED When the conditioning cycle has been initiated, the analyzer checks for proper aspiration of the conditioning solution using the sample sensor. If the solution is not detected in the proper time, this error message will be displayed. Possible causes and remedies: • Ensure that a sufficient volume of conditioning solution is presented for aspiration and no air bubbles are present as solution is aspirated. • Check to ensure that the solution is being properly aspirated through the sampling mechanism. The sample path must be free of leaks or clots. • Verify that sample sensor is correctly plugged in and perform the SAMPLE SENSOR TEST to verify its proper operation. • Check pump tubing and replace as necessary to ensure correct pump rate. INTERFACE ERROR This message is displayed only during the INTERFACE TEST. Pins 2 and 3 must be shorted together to perform the INTERFACE TEST. Make sure that the pins are not shorted to chassis ground. Possible cause and remedy: • Replace SBC Card. PAPER JAM OR PRINTER DEFECT This message is displayed when the printer head is jammed and tries to print. It is a temporary message that is displayed for 2 seconds and then sample results are displayed. To clear paper jam remove printer from the analyzer and remove jammed paper. Replace printer and retry. The printer can be removed by grasping the rear edge of the printer assembly and pulling it to the front. The printer can be removed with the Analyzer power on. To free up jammed paper, turn the small gears on the left side of the printer module. 64 CHECK ELECTRODES This message is displayed when either of the following conditions are present. 1. More than six aspirations of Standard A are required for all electrode channels. 2. The difference between voltage A and B is out of specification for all channels. Possible causes and remedies: • Electrodes are not plugged in. Check the slide mechanism to ensure it is in the correct position and firmly pushed into electrode connectors. • Perform Daily Maintenance. • Check or replace reference electrode. • Replace ISE SnapPakTM. NA NOT CAL’D K NOT CAL’D CL NOT CAL’D CA NOT CAL’D LI NOT CAL’D These messages will be displayed when a specific electrode does not calibrate properly during a calibration sequence. If more than six standard draws are required or the difference between Standard A and Standard B voltages is out of range, the NOT CALIBRATED message will be displayed for each channel which exhibits either of these conditions. A copy of the calibration report should be printed to provide the electrode output voltages measured during calibration. The electrode voltage range table identifies correct voltage ranges for each electrode parameter. If the difference between Standard A and Standard C (9180/9181 only) is out of range for Li+ or Na+, LI NOT CAL’D will be displayed. Possible causes and remedies: • Check to ensure calibration reagents are transported correctly. Test for leaks, blockages, bubbles, or improper pump flow rate. • Check or replace ISE SnapPakTM. • Check whether electrodes are plugged in properly. Check the slide mechanism to ensure it is in the correct position and firmly pushed into electrode connectors. Clean and/or replace electrode. • If A-C is out of range for Na+, repeat the calibration or replace the ISE SnapPakTM. • Check or replace SBC Card. 65 ELECTRODE VOLTAGE RANGES 9120, 30, 40 Electrode Na + K+ ClCa++ Standard A -600 -700 -3100 -2600 Standard B to +2400 to +1000 to -100 to +1400 -1600 -2500 -1100 -2100 to to to to +2200 +500 +1800 +2700 Allowable Difference A - B (9120/9130) (9140) +720 to +2000 +250 to +680 +520 to +1800 +470 to +1200 -520 to -1200 not used not used -480 to -900 ELECTRODE VOLTAGE RANGES 9180, 81 Electrode Na + K+ ClCa++ Li+ Standard A -600 -700 -3100 -3100 -3100 to to to to to +2400 +1000 -100 +1000 +1900 Standard B -1600 -2500 -1000 -2300 -3600 to to to to to +2000 +500 +3000 +2500 +1400 Standard C -600 -700 -3100 -3100 -2600 to to to to to +2400 +1000 -100 +1000 +3400 +250 +470 -370 -350 +1 Allowable Difference A-B A-C to +680 -50 to +50 to +1200 -40 to +40 to -860 not used to -660 -150 to +150 to +760 -1730 to -285 CLOG CHECK FLUID PATH After completion of sample measurement or calibration, the analyzer will monitor the sample sensor to determine if the sample path has been cleared. This message will be displayed if the sample path has not been cleared. Possible causes and remedies: • Check for blockages in the sample path, especially in the sample probe, the tubing to the sample sensor and in the sample sensor. • Check sample sensor is securely plugged in and check sample sensor test to ensure correct operation. • Check peristaltic pump and tubing are correct and all tubing is properly in place. ↑↑↑↑ ↓↓↓↓ In case the analyzer displays arrows up or arrows down instead of sample results, the concentration of the sample is outside of the measurement range. Possible causes and remedies: 66 • If the sample is a urine sample, arrows up instead of the K result indicate that further dilution of the specimen is required. • Check for proper sample preparation. • Ensure that the sample is correctly aspirated into the measuring chamber and ensure small air bubbles are not present. • Check for proper aspiration of Standard A. ↑ ↓ On the 9140, 9180 and 9181 models, the calibration report will print an arrow up or down instead of the actual temperature, if the temperature measured is out of range (10.0°C -40.0°C). The temperature sensor is located in the right side electrode holder. Possible causes and remedies: • Ensure that sample sensor cable is securely plugged in. • Check whether room temperature is within specified limits (15°C to 32°C / 60°F to 90°F). • Perform temperature adjustment procedure. • Replace SBC board or right side electrode holder. ERR The analyzer will display ERR in place of sample results when the analyzer is unable to obtain valid voltage readings from the electrode (A/D over- or underflow). Possible causes and remedies: • Ensure that the electrodes are securely in place and plugged into the analyzer. • Check to ensure proper filling of the reference electrode has occurred. • Ensure proper sampling and proper sample preparation. Check for air bubbles in the sample. PERFORM DAILY MAINTENANCE This message will be printed at the end of a sample report when cleaning or conditioning have not been performed within the last 24 hours. This message is printed only. Perform Daily Maintenance to clear this message. 67 REPLACE FLUID PACK When the monitored fluid level in the ISE SnapPakTM reaches 5% remaining, the analyzer will print REPLACE FLUID PACK at the end of each sample report. This message is printed only. Replace the ISE SnapPakTM following the instructions outlined in the Operator Manual. To maximize the life of the ISE SnapPakTM, continue running the analyzer until a STANDARD A NOT DETECTED message is displayed. This will ensure that the ISE SnapPakTM is completely depleted before replacement. CHECK TEMPERATURE (9140/9180/9181 only) On the 9140/80/81 models, the analyzer will display CHECK TEMPERATURE at the end of each measurement, if the temperature measured is out of range (10.0°C to 40°C). The temperature sensor is located in the right side electrode holder. Possible causes and remedies: • Ensure that the sample sensor cable is securely plugged in. • Check whether room temperature is within specified limits (15°C to 32°C / 60°F to 90°F). • Perform temperature adjustment procedure. • Replace SBC board or right side electrode holder. VALVE OVERTEMP! CHECK VALVES In case one of the valve solenoids overheats, the message VALVE OVERTEMP! CHECK VALVES will be displayed. Each solenoid incorporates a thermo-fuse, which will reset automatically. Possible causes and remedies: 68 • Turn power off for at least one hour. • Check fuse F3 (24V). • Check whether room temperature is within specified limits (15°C to 32°C / 60°F to 90°F). ERROR: UPPER NEEDLE SENSOR If probe movement to the upper position is not detected within a certain time period, the above message is displayed. Possible remedies: • Check for foreign material that may prevent the probe from moving freely. • Contact AVL for technical assistance. ERROR: LOWER NEEDLE SENSOR If probe movement to the lower position is not detected within a certain time period, the above message is displayed. Possible remedies: • Make sure the fill port is installed correctly. • Check for foreign material that may prevent the probe from moving freely. • Contact AVL for technical assistance. WHEEL MISSING OR SAMPLER DEFECT During the homing sequence, the sampler checks for the sample wheel to be present. Possible remedies: • Make sure the wheel is present and seated correctly. • Replace sample wheel. • Replace sampler. 69 SAMPLER JAMMED OR DEFECTIVE The analyzer checks for correct movement of the sample wheel. If the sample wheel does not move at the expected speed, the above error message is displayed. Possible remedies: 70 • Check for obstructions preventing the sample wheel from moving freely. • Replace sampler. 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. 71 7 Electronic Diagrams AVL 9120, 30, 40, 80 Analyzers System Block Diagram 9120, 30, 40, 80 ........................................ 74 System Block Diagram 9181 .......................................................... 75 System Interconnect 9120, 30, 40 .................................................. 76 SBC PCB - Power Supply 9120, 30, 40 ........................................ 77 SBC PCB - Valve Drivers 9120, 30, 40 ......................................... 78 SBC PCB - Pump Motor Driver/Door Detect 9120, 30, 40 ............ 79 SBC PCB - Input Amplifiers 9120, 30, 40 ...................................... 80 SBC PCB - Temperature Circuit 9120, 30, 40 ............................... 81 SBC PCB - Analog Selector and A/D Converter 9120, 30, 40 ....... 82 SBC PCB - Microprocessor 9120, 30, 40 ..................................... 83 SBC PCB - Printer/Display Drivers 9120, 30, 40 ........................... 84 Printer Daughter PCB 9120, 30, 40, 80, 81 .................................... 85 Lamp PCB 9120, 30, 40 ................................................................ 86 Display Daughter PCB 9120, 30, 40 ............................................... 87 72 AVL 9180/81 Analyzers System Interconnect 9180/9181 .......................... .......................... 88 SBC PCB - Power Supply 9180/9181 ........................................... 89 SBC PCB - Valve Drivers 9180/9181 ............................................ 90 SBC PCB - Pump Motor Driver/Door Detect 9180/9181 ............... 91 SBC PCB - Input Amplifiers 9180/9181 ......................................... 92 SBC PCB - Temperature Circuit 9180/9181 .................................. 93 SBC PCB - Analog Selector and A/D Converter 9180/9181 .......... 94 SBC PCB - Microprocessor 9180/9181 ........................................ 95 SBC PCB - Printer/Display Drivers 9180/9181 .............................. 96 SBC PCB - Fluid Pack Detector 9180/9181 .................................. 97 Lamp PCB 9180/9181 ................................................................... 98 Display Daughter PCB 9180 ........................................................... 99 73 9120, 30, 40, 80 Analyzer Block Diagram SBC Board Preamplifier Na Electrode K Cl Reference Electrode Fluid Pack Detector Sensor (9180 only) Na Amp K Amp Cl/Ca/Li Amp Display Board Display Driver JP4 Display Module YES/NO Switches Temp Sensor (9140/9180 only) Sample Sensor JP2 GND Temperature Control (9140/9180 only) Analog Selector and A/D Converter Printer Driver JP1 Sample Sensor/Temp Sensor JP1 Printer Assembly Microprocessor Power Supply +22VDC / +10VDC +5VDC / -5VDC (9180) +8VDC / -8VDC +22VDC / +12.5VDC Peristaltic Pump Driver JP5 P.

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 pin pin pin pin pin pin pin pin 1...sample ground...GND 2...receive data....RxD 3...send data.......TxD 4...NC 5...signal ground...GND 6...NC 7...RTS 8...CTS 9...NC (NC=Not Connected) 107 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 (→). 9.2 Example Data String Information Automatic Calibration Report sx* AVL 9130 *crcrlfELECTROLYTE ISEcrcrlf03JAN92 10:51crcrlf*CALIBR REPORT*crcrlfcrcrlfDailyMaintenancecrcrlf Performed Last: crcrlf02JAN92 10:35crcrlfcrcrlf Standard AcrcrlfNa = -112mV (3)crcrlfK = -1392mV (3) crcrlfCl = -106mV (3)crcrlfcrcrlfDifference A-Bcrcrlf Na = 1402mV ( )cr crlfK = 1032mV ( )crcrlfCl = -1006mV ( ) crcrlfcrcrlfFluid Pack:crcrlf6 8% Remainingcrcrlfcrcrlfex Serum Sample Report sx* AVL 9130 *crcrlfELECTROLYTE ISEcrcrlf03JAN92 10:59crcrlfcrcrlf Name: ..........crcrlf ..........crcrlfSample: SERUMcrcrlfcrcrlf Sample No.13 crcrlfcrcrlfNa= 159soh mmol/LcrcrlfK = 5.4 mmol/LcrcrlfCl= 122soh mmol/Lcrcrlfcrcrlf*PERFORM DAILY *crcrlf*MAINTENANCE ! *crcrlfcrcrlfex 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. 108
