Perform the following tests to verify proper operation of the
Capacitor Charge Unit:
1. Insert the charge probe into an alarm fuse position that has
a load connected to it. The charge probe is keyed and can
only be inserted in the correct position.
2. Operate the CAP CHG/TEST pushbutton.The red LED
lights, then extinguishes, indicating the load capacitor has
been charged. Release the button at this time. If the yellow
LOAD FAULT LED lights, operate the pushbutton a
second time. If the LOAD FAULT LED lights a second
time, investigate the problem. There is probably a fault at
the load.
Note: If the pushbutton is held for more than five
seconds, the charge tool circuit will remove its output
and light the FAULT LED.
3. When the red LED extinguishes, indicating the load
capacitor has been charged, remove the charge probe and
insert load fuse. This should be done immediately after
the red LED extinguishes.
4. Insert alarm fuse.
5. Repeat Steps 1 through 4 for the remaining active fuse
positions.
