Maintenance
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)
•
LVD/Fuse Board LEDs and fuses
LVD/R LEDs
Two LEDs on the LVD/Fuse Board are used to indicate the
status of the low-voltage disconnect/reconnect circuit.
1. 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.
2. 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. The contactor, however, is still closed.
Fuses
Fuses F1 through F12 (see Figure 7-1) are also located on the
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. See “Troubleshooting” below for details on
replacing blown fuses.
Note
Review all safety statements and warnings in Section 4 before
performing any maintenance.
