Table 5-6 FPS Powered Up but Gun Does Not Switch On When Commanded To Do So

Symptoms
TCS displays SRC1_GON_ALM (= Source 1 Control Go On Timeout Alarm)
•
Remote Controller: Gun Ready light inside Gun Control panel's OFF button fails to light
•
EBC issues FPS Gun Ctl Go On Timeout alarm
•
Possible Causes
1. Faulty or loose cable connections.
2. Confirm Gun Ready signal
3. Emitter damaged
If the preceding steps have failed to correct the fault, perform the following procedure:
1. Switch off the power supply.
2. Disconnect HV output cable.
3. Switch on the power supply and the HV and leave them switched on for no more than 9 seconds, observing whether the
symptom persists during that interval.
DO NOT leave the high voltage on for more than 9 seconds with the HV cable disconnected. Doing so will
result in the emitter's filament burning out.
4. If the symptom is not in evidence during Step 3, troubleshoot the HV path and emitter assembly, following the instructions
in the e-gun manual. If the symptom persists during Step 3, reconnect the HV output cable to J101, switch the power
supply back on, and proceed with the troubleshooting steps described below.
4. Fault conditions whose investigation
requires removal of FPS top cover.
