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 4-13 and Figure 4-14 for 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.
