The Low Voltage Load Disconnect (LVLD or LVD) feature controls a high
capacity contactor that disconnects the load during extremely low volt-
age conditions. The system loads are automatically reconnected 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 13 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) and the associated breakers and fuses used for battery protec-
tion.

3.9 Low Voltage Load Disconnect
NOTE:
LVLDs are not installed in secondary voltage distribution banks.
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 14.
NOTE:
Setting the LVD Override switch to OVERRIDE generates an alarm on the CXC. See the
"Digital Alarms" section under "Configure Alarms" in the controller software manual.
