NOTE:
Before performing this procedure, refer to the OVERVIEW, Section 4.7 .
1.
CAUTION:
Remove only a filter fuse in this step, not a load fuse. At the PDF, remove filter fuse
one (FF1 location such as upper, center, and left) from the first equipped filter fuse panel. Wait
approximately 10 seconds for the capacitor to discharge and the filter fuse LED (red) to light
(DS2.2).
NOTE:
Removal of the filter fuse will result in a minor alarm.
2.
At the PDF, remove the capacitor charge probe
CAP CHG
from the control panel.
3.
Insert the
CAP CHG
in the vacated filter fuse position. Push and twist the probe clockwise to lock it in place.
4.
Press and hold the
CAP CHG TEST
button and observe the control panel for the following:
(a)
The
CAP CHG
LED (red) does not go out.
(b)
The
CHG CKT
fuse blows.
(c)
On the filter fuse panel, the filter fuse LED does not go out.
If 4(a), 4(b), or 4(c) occurs, replace the charge circuit module (ED-83024-30, G5 or G6). Repeat
Steps 1 through 4 with the new charge circuit module. If this did not correct the problem, the charge
probe may need to be replaced. (Contact a qualified service representative.) To bring the filter fuse
capacitor back on line in absence of a working charge circuit, obtain at least four (4) of the filter fuses
(KS-19780, L26). Insert one of these fuses into the FF1 holder. If the DS2.2 LED does not go out,
quickly remove the fuse and replace it with another. Repeat this procedure until the DS2.2 LED goes
out. If 4(a), 4(b), or 4(c) does not occur, the capacitor charge circuit is functioning properly.
5.
Remove the charge probe from the filter fuse holder (FF1) and quickly reinsert the filter fuse. Replace the
charge probe in its holder on the control panel.
Results:
PDF Charge Circuit tested with good results, or corrective action to correct any defects
found with the probe or circuit pack must be taken.
6.
STOP. YOU HAVE COMPLETED THIS PROCEDURE.
