4.9.4 Engine and Transfer Time Delays
The engine start and transfer time delays prevent
engine start and load transfer caused by brief variations
in the utility power source.
4.9.5 Load Control Time Delay
The load control time delay allows delayed starting of
large motor loads (such as air conditioners), preventing
simultaneous starting of large motors after transfer to
the generator set. The load control time delay is fixed at
5 minutes. It is not adjustable.
The load must be connected to the load control output
on the interface board of the Model RRT transfer switch.
See the transfer switch operation and installation
manual for connection instructions.
4.9.6 Model RRT ATS Connection
See Figure 4-11 for Model RRT transfer switch
connection to the generator set.
