3.6 Low Voltage Load Disconnect
The Low Voltage Load Disconnect (LVLD or LVD) feature controls a
high capacity contactor that disconnects the load during extremely
low voltage conditions. The system loads are automatically recon-
nected once AC is restored and battery voltage has risen above a
preset value.
The parameters for LVD activation and control are set in the Controls
> Configure Controls menu in the CXC controller. Refer to the section
titled "Controls" in the controller software manual.
Each TPL fuse circuit in a given distribution bay, can have its own
LVD. Figure 11 shows the LVDs in a distribution module with two
banks of TPL fuses.
An LVD is also an option for a bank of breakers in a distribution
module.
LVDs can also be configured as Low Voltage Battery Disconnects
(LVBD).
LVD Override
Activation of all LVDs, by the controller, is through Relay 1 (LVD 1).
To manually override the LVDs, position the LVD Override switch to
OVERRIDE. This switch is mounted inside the door of the distribution
module with the controller—see Figure 12.
