5.4 Troubleshooting Procedures
Before performing any of the procedures described on this page, perform the
procedure described in section 5.4.1.

Table 5-8 No Beam Emitted After HV and Gun Are Switched On

Symptom: HV and gun are switched on, but no beam is emitted
For additional information about this fault mode, see Ishikawa Diagram #3.
Possible Causes
1. Faulty or loose connections.
2. Confirm HV Ready signal
3. Confirm Gun Ready signal
4. Emitter damaged
5. Confirm HV IS ON signal
6. Confirm GUN IS ON signal
7. Fault conditions whose investigation
requires removal of FPS top cover.
Before performing the following procedure, perform the procedure described in
section 5.4.3.
Symptom: HV fluctuates or sags from requested level
For additional information about this fault mode, see Ishikawa Diagram #4.
Possible Causes
1. Incorrect or fluctuating line voltage
2. Faulty or loose cable connections.
3. Emitter damaged
4. System incorrectly grounded for HV
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.
