Issue 6 August 1998
Acceptance Testing 5 - 7
2. Replace the blown fuse with a good fuse. The alarms
should retire and the MNF LED extinguish.
3. Repeat Steps 1 and 2 for all minor fuses, including F502
through F509 on the LVD/Fuse Board.
4. Replace F510 with a blown fuse. The MJF (Major Fuse
Alarm) LED should light, and the NORM LED should go
out. Check the terminal blocks for the following major
alarms:
MJFE, PMJE, PMJA, and PMJV
5. Reinsert the good fuse, and note that the alarms retire and
that LEDs return to normal.
6. Repeat Steps 4 and 5 for major fuses F511 and F512.
7. For plants equipped with battery string disconnect breakers
only, the Open String Alarm (OS) is hardwired from the
controller terminal blocks to an auxiliary fuse alarm input
on the LVD/Fuse Board. If OS is wired into the LVD/Fuse
Board, turn one disconnect breaker off to verify that the
desired MJF or MNF alarm and associated power alarms
are issued. Turn the breaker back on and note that the
alarms retire.
8. Repeat Step 7 for each battery string disconnect breaker.
Remote On/Off
(TR Signal) Test
1. Attach one end of a piece of wire to Discharge Ground
(DG) on pin 1 of TB101 on CP1. This wire will be used to
ground the TR input signals to simulate a Rectifier
Sequence Controller or other remote on/off device for
controlling rectifiers.
2. Touch the free end of the wire, in turn, to each of the TR
inputs on the terminal block pins listed below.
