Ambient Temperature Sensor Failure Rap - Xerox WorkCentre 5687 Series Service Manual

09-375 Ambient Temperature Sensor Failure RAP

09-375 The average ambient temperature is out of limits.
Initial Actions
Switch off the machine, then switch on the machine, GP 14.
Reposition P/J46 on the relative humidity sensor / ambient temperature sensor and P/J7 on
the IOT PWB.
Procedure
Enter dC330 code 09-375, ambient temperature sensor, Q09-375. Press start. Observe the
displayed state of Q09-375. Figure 1. Open the left hand door, gently blow on the temperature
sensor PWB. Observe again the displayed state of Q09-375. The
changed.
Y N
Go to Flag 1. Check for +5V at P/J7 pin 3 on the IOT PWB. +5V is present.
Y N
Go to the 01E +5V Distribution RAP.
Go to Flag 1. Disconnect P/J46. Check for +5V at P/J46, pin 1. +5V is present.
Y N
Check the wiring between P/J7 on the IOT PWB and P/J46, GP 7. Repair the wiring
as necessary.
Install a new relative humidity sensor / ambient temperature sensor, (32-38 ppm) PL 9.22
Item 4, (45-87 ppm) PL 9.20 Item 4.
If the fault persists, perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is
installed, PL 1.10 Item 2.
The ambient temperature sensor is working correctly.
If the fault is intermittent, perform the steps that follow:
• Check the wiring, GP 7. Repair if necessary, REP 1.2.
• Make sure that the P/Js are correctly and securely connected, GP 11.
