5 - 4 Acceptance Testing

3. Momentarily short together pins 2 and 6 on TB101 on CP1
with a piece of wire. This simulates an equalize initiation
signal from an external timer panel. Verify that the
equalize LED lights and the rectifiers change to equalize
mode.
4. Momentarily short pins 2 and 7 on TB101 with a piece of
wire. This should stop equalize and return the plant to float
mode.
If the plant is equipped with a CP2, initiate the equalize
mode from a terminal. After verifying proper operation,
return the plant to the float mode.
High Voltage
Shutdown and
Restart Test
NOTE
This test cannot be performed on a live plant powering active
loads. If possible, batteries should be disconnected from the
plant to allow the plant voltage to be reduced easily.
1. Identify the high voltage shutdown threshold for float
operation on DIP switch SW102.
2. Set all rectifiers to non-load share mode.
3. Turn on two rectifiers and adjust the test load so that each
rectifier delivers more than 10% of its full load current. Do
not load plant more than 90% of the capacity of one
rectifier.
4. Set the controller meter to read VOLTS, and verify that the
green NORM indicator is the only LED that is lit on the
controller.
5. At any one rectifier, slowly adjust its output voltage up
until a shutdown occurs. This should occur at the specified
HV shutdown threshold within the tolerance indicated in
Table 2-B. Verify that the rectifier being adjusted has shut
down.
6. Note that the NORM LED goes out and the yellow RFA
LED lights on the controller. If enough rectifier capacity is
