SM-DU Circuit Card 

The SM-DU is used in supplemental bays in place of ACU+ controller.  The SM-DU monitors the bay and reports to the controller.  The 
controller sends commands to the SM-DU to fulfill battery management and load control functions according to the received data. 

There are three (3) status and alarm indicators located on the SM-DU.  The functions of these indicators (from top to bottom as shown in 
the illustration) are as shown in 

Table 1

.  Refer to 

Figure 6

 for location. 

Table 1.

SM-DU is non-operational. 

Flashing 

A 1/3Hz flashing indicates the 
SM-DU is being identified by the 

Controller. 
A 1Hz flashing indicates a 

communication failure.
