Optional LVD Driver Lite Circuit Card
The optional LVD driver lite circuit card contains an LVD inhibit switch and indicator. Refer to Figure
Caution: If the switch is returned to the ON (normal) position when low voltage disconnect alarms are active, a low voltage disconnection will occur.
Warning: While the LVD inhibit switch is in the OFF (inhibit) position, a low voltage disconnection will not occur if battery or load voltage decreases below the low voltage disconnect setpoint. For maximum battery protection, this switch should NOT be left in the OFF (inhibit) position.
