Optional LVD Driver Circuit Card

The optional LVD driver circuit card contains an LVD inhibit switch and indicator. Refer to Figure 2-3.This card is required for 2-, 3-, or 4-row distribution cabinets that contain three or more LVD contactors (LVBD and/or LVLD); or if the distribution cabinet is equipped with an LVBD contactor rated 1200A or higher.

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.

LVD Inhibit

Active Indicator

Illuminates when the low voltage disconnect circuit has been disabled through the use of the LVD Inhibit switch.

Note: The UP position will not close the LVBD contactor

LVD Inhibit Switchif the battery is manually disconnected using the Manual Battery Disconnect Switch.

Momentary UP / Middle / Down

Momentary UP Position: Closes all LVD Contactors (inhibit mode).

Middle Position: OFF (ACU+ DOES NOT control LVD’s) (inhibit mode).

DOWN Position: ON (ACU+ controls LVD’s).
