General Information
Automatic Transfer Switch Owner’s Manual 7
Four LEDs, located on the SACM (B), illuminate when a
load is connected and powered.
The SACM has a test button (C) that is used to simulate
an overload condition. This button operates even when
the transfer signal is inactive. The generator control wir-
ing is connected to terminals (D).
Smart Management Module (SMM)
See Figure 2-4 . Any loads, including central air condi-
tioners, can be managed using an optional Smart Man-
agement Module (SMM). The system can accommodate
up to eight individual SMMs.
Figure 2-4. Smart Management Module (SMM)
NOTE: SMMs are self-contained and have individual
built-in controllers.
Application Considerations
Generator overload condition is determined by generator
frequency. Loads are shed when frequency is less than
58 Hz for three seconds or less than 50 Hz for ½ second
(for 60 Hz systems).
The SACM can be used in conjunction with individual
SMMs to manage a combined total of eight loads.
•
Use Priorities A/C 1-4 on the SACM as the top priori-
ties, then up to four SMMs as Priorities 5-8.
•
Use only select A/C priorities on the SACM as the top
priorities, then use additional SMMs as the remaining
priorities.
•
A SMM can share a priority with an A/C priority on
the SACM provided the generator is sized to handle
the combined surge load from both appliances. Shar-
ing priorities can allow up to 12 loads to be managed
in a properly sized system.
In any combination of modules, the recovery times after a
loss of utility power or shutdown due to overload are
shown in
Priority Settings
.
Refer to the SMM Owner’s/Installation Manual for
