Controls and
Indicators
Operating controls and indicators on the battery plant are listed
below.
Controller and
Rectifier
Operating controls and indicators for the controller and rectifier
include switches and LEDs described in the Product Manuals for
these units.
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 F12 are also located on the CP5 LVD/Fuse
Board and provide power for controller functions and rectifier
regulation (see Figure 4-1). 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. See paragraph “Troubleshooting” for
details on replacing blown fuses.
