Controls and
Indicators
Operating controls and indicators on the battery plant are listed
below.
Controller LEDs
and Switches
See Controller Manual.
Rectifier LEDs
and Switches
See Rectifier Manual.
CP5 Fuse Board
LEDs and Fuses
Two LEDs on the CP5 Fuse Board are used to indicate the status
of the low-voltage disconnect/reconnect circuit.
•
The red “LVD OPEN” LED indicates that the
disconnect/reconnect contactor is open and, therefore, that
batteries are disconnected from the rest of the battery plant.
•
The yellow “LVD FAIL” LED indicates that only one of
the two redundant low-voltage detectors has directed the
contactor to open and that the disconnect circuit may have
failed.
Fuses F1 through F21 are also located on the CP5 LVD/Fuse
Board and provide power for controller functions and rectifier
regulation. When a fuse blows the colored indicator (white or
orange) pops up and an alarm signal is transmitted to the
controller. The fault should be cleared before replacing a blown
fuse. Refer to the ECS Controller manual for troubleshooting
procedures.
