DANGER: HIGH VOLTAGE

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

Procedure

1. Faulty or loose connections.

Make sure that all HV and FPS connections are correctly and securely made.

2. Confirm HV Ready signal

See Table 5-3.

3. Confirm Gun Ready signal

See Table 5-4.

4. Emitter damaged

Follow instructions in gun manual to troubleshoot emitter issues.

5. Confirm HV IS ON signal

See Table 5-5.

6. Confirm GUN IS ON signal

See Table 5-6.

Fault conditions whose investigation

requires removal of FPS top cover.

DANGER: HIGH VOLTAGE

Before performing the following procedure, perform the procedure described in

section 5.4.1.

Table 5-9 HV Output Unstable

Symptom: HV fluctuates or sags from requested level

For additional information about this fault mode, see Ishikawa Diagram #4.

Possible Causes

Procedure

1. Incorrect or fluctuating line voltage

Confirm input line voltage

2. Faulty or loose cable connections.

Make sure that all power module and FPS cable connections are

correctly and securely made.

3. Emitter damaged

Follow instructions in gun manual to troubleshoot emitter issues.

4. System incorrectly grounded for HV

Make sure that grounding instructions in e-gun manual have been

correctly implemented.

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.

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.
