CHANGING THE ACU+ LVD CONTROL

LEVEL FOR A CONTACTOR

The ACU+ Controller has two available LVD control levels (LVD1 and LVD2). The level used to control a contactor is determined by which connector on the LVD circuit card its control leads are plugged into. To change the LVD control level for a contactor, simply switch which LVD connector it is plugged into (if an open connector is available) on the LVD circuit card. Refer to Figure 4-13and Figure 4-14for connector location and function.

Note: DO NOT change a Low Voltage Load Disconnect contactor to LVD Control Level 2 (LVD2) if the system is furnished with a Low Voltage Battery Disconnect contactor.
