2.10.4 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.
The engine cooldown time delay allows the engine to
run after the loads have been removed. The engine
stops before the cooldown time delay expires if the
temperature drops below the cooled-down temperature
level, or if the temperature rises during the cooldown
cycle.

2.10.5 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.
