Table 5-23 HV Is Switched On but FPS Front Panel HIGH VOLTAGE ON LED Fails To Light
Symptoms
•
HVPS Front Panel: HV switched on, with LEDs indicating nominal HVPS state
•
FPS Front Panel: HIGH VOLTAGE ON LED is unlit
Possible Cause Procedure
1. FPS is not powered up.
1.
Make sure that FPS is switched on. If switch is on, POWER ON LED is lit,
and HV is switched on, proceed to Step 2. If FPS switch is in the ON
position but the
POWER ON LED is not lit, see Table 5-24.
2. HV IS ON signal is not present at
FPSB connector J102.
2.
Check pins J102 Pin 1 for the HV IS ON signal. If not present, proceed to
Step 3.
3.
Fault condition(s) whose investigation
requires removal of HVPS top cover

Table 5-24 FPS Is Switched On but Its POWER ON LED Fails To Light
Symptoms
•
HVPS front panel: FILAMENT POWER LED on turns red
•
FPS #1 front panel: POWER ON LED on fails to light when FPS is switched on
•
EBC displays FPS Gun Ctl Go On Timeout alarm message
For additional information about this fault mode, see Ishikawa Diagram #16.
Possible Cause Procedure
1. HVPS rear panel connector J1 not
supplying 208 V ac power
1. Disconnect FPS power cable from HVPS J1 and check J1 for 208 V ac output. If no
voltage or incorrect voltage is indicated, proceed to Step 2. If voltage is correct,
skip to Step 4.
2. HVPS rear panel fuses F1 and/or F2
blown.
2. Check fuses and replace as necessary. After replacing either fuse, repeat Step 1 of
this procedure. If correct voltage is then detected at J1, reconnect power cable
between J1 and FPS #1.
3. Faulty FPS power cable.
3.
Reconnect the FPS power cable to J1 and disconnect it from the FPS.
Measure the female end of the cable for 208 V ac. Replace cable as
necessary.
4. Blown fuses on FPS input power line. 4. Check and replace fuse(s) as necessary, as described in section 5.5.
