6.6 SAMPLER ERRORS

6.6.1 Replace Sample Rack

Monitor Timing: Monitor every 50 msec during interruption

Monitor Method: The micro switch in the sample rack table

CA-500’s Action: Warning at each analysis.

(1) Probable Cause

1. The sampler rack is removed.

2. The sampler rack is not properly mounted.

3. Failure of sampler rack sensor assembly

4. Failure of wiring cord (wiring cord with spiral)

5. Failure of PCB No. 6362

(2) Confirmation by the operator

1. Place the sampler rack properly.

(3) Confirmation by Service Engineer

1. Check the dirt on sample rack table and/or it is free of foreign matters.

2. Short-circuit the pin 20 and pin 18 of relay connector. If it can be monitored on the switch sensor

screen, the sample rack drawer might be faulty. Check the harness and sample rack sensor.

3. If the above step 2 does not solve the trouble, short-circuit the pin 14 and pin 12 of CN111 on PCB No.

6362. If this solves the trouble, the wiring cord (wiring cord with spiral) is faulty. If not, the PCB No.

6362 is faulty.
