Possible Cause
Procedure
1. Incorrect or fluctuating line voltage
1. Confirm input line voltage
2. Faulty or loose connections.
2. Make sure that all HV and FPS connections are correctly and securely made.
If preceding steps have failed to correct the fault, perform the following procedure:
1. Switch off the power supply.
2. Disconnect HV output cable from HVPS J1.
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.
CAUTION
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 emitter assembly, following the instructions in the e-gun
manual. If the symptom persists during Step 3, reconnect the HV output cable to HVPS J1, switch the power supply back
on, and proceed with the troubleshooting steps described below.
