9-684 ADC Shutter
The machine logic detected an ADC Shutter operation failure.
Procedure
BSD 9.16, 9.31D
Enter dC330 [009-078]. The ADC Shutter Solenoid energized.
YN
There is +24VDC from P/J 536-A7 on the I/F PWB to GND.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues, replace the ADC Sensor (PL 1.3).
Enter dC330 [009-078]. There is 0VDC from P/J536-A8 on the I/F PWB to GND.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues, replace the MCU PWB (PL 13.1). If the problem continues,
replace the ADC Sensor (PL 1.3).
Enter dC330 [009-079]. The voltage from P/J 536-A6 on the I/F PWB to GND changed to
0VDC momentarily.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues, replace the MCU PWB (PL 13.1). If the problem continues,
replace the ADC Sensor (PL 1.3).
Check the wires and connectors. If the check is OK, replace the ADC Sensor (PL 1.3).
After checking that no failures are detected during normal operation, go to call closeout.
