Table 5-4 HVPS and FPS Are Powered Up but GUN READY State Not Achieved/Confirmed

Symptoms
TCS displays SRC1_GON_ALM ( = Source 1 Gun Control GO ON Timeout Alarm)
•
EBC issues FPS Gun Ctl Go On Timeout alarm
•
Possible Causes
1. Confirm that all interlocks are made.
2. Faulty or loose cable connections.
3. GUN ENABLE input at Pin 6 on FPS
connector J101 is high.
4. Fault condition(s) whose investigation
requires removal of FPS top cover.
Before performing the following procedure, perform the procedure described in
section 5.4.1.

Table 5-5 HVPS Powered Up but HV Does Not Switch On When Commanded To Do So

Symptoms:
TCS displays PSU1_GON_ALM (= Power Supply Control Go On Timeout Alarm)
•
HVPS Front Panel: HV ON LED fails to light Green
•
EBC issues HVPS Go On Failure alarm
•
Possible Causes
1. HV READY signal is not present.
2. After remote HV GO ON command is
issued, HV ON
signals are not supplied
via Pins 8-9 of HVPS J4.
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.
3. Fault condition(s) whose investigation
requires removal of HVPS top cover.
CV-6SLX User Manual
1. See Table 5-2.
2. Make sure that all power module and FPS cable connections are correctly and
securely made.
3. Check input at Pin 6. If high, proceed to Step 4. If low, investigate the GUN
ENABLE loop upstream of the FPS.
4. Contact Temescal Field Service.
DANGER: HIGH VOLTAGE
1. See Table 5-3.
2. Verify that the remote HV GO ON signal is supplied by EBC or PLC-based
system controller.
CAUTION
