  • Page 54: Description Of Modules

    Description of Modules 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.
  • Page 55 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.
  • Page 56 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.
  • Page 57 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.

  • Page 58: Fluidic Module

    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 , to the fill port, through the sample needle and is sensed by the sample sensor.
  • Page 59 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 performed annually. For removal of the tubing, first remove the ISE SnapPak from the reagent compartment.

  • Page 62: Electronics

    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.
  • Page 63 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.
  • Page 64 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.

  • Page 65: Maintenance And Troubleshooting

    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.

  • Page 66: Error Messages And Troubleshooting

    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.
  • Page 67 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.
  • Page 68 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.
  • Page 69 NO SAMPLE This message is displayed when any of the following conditions occur: During sampling, either a bubble in the sample is detected or thesample size is smaller than the minimum sample required. The sample door is opened and no sample is fed into the analyzer. Sample door is not closed within 20 seconds after sample is detected.
  • Page 70 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: •...
  • Page 71 CHECK ELECTRODES This message is displayed when either of the following conditions are present. More than six aspirations of Standard A are required for all electrode channels. The difference between voltage A and B is out of specification for all channels.

  • Page 73 ↑ ↓ 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.
  • Page 74 REPLACE FLUID PACK When the monitored fluid level in the ISE SnapPak 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 SnapPak following the instructions outlined in the Operator Manual. To maximize the life of the ISE SnapPak , continue running the analyzer until a STANDARD A NOT DETECTED message is displayed.
  • Page 75 • 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.

  • Page 77: Adjustments

    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.
