over all other start signals.
System Stop (AUTO-OFF). Press AUTO and OFF
D
simultaneously to send a stop signal to cancel the
system start.

Communications-based

SiteTecht or a CAN-based remote panel.
Engine Cooldown
Cooldown is a state where the generator is running at no
load to allow hot engine components time to cool slowly
before the engine is stopped. In paralleling applications,
this occurs with the circuit breaker open.
When the generator set is running in AUTO mode
(AUTO-RUN), an engine cooldown cycle begins when
the remote start input is deactivated. Also, if stopping
due to a stop signal, a cooldown cycle begins.

If the Cooldown Override is disabled (OFF) in the
Generator Configuration Menu, coolant temperature is
ignored. The generator will enter cooldown when the
start signal is removed, only if in AUTO. The engine will
run for a period of time equal to the Cooldown Delay
parameter setting, regardless of the coolant temperature.
If the Cooldown Override is enabled (ON) in the
Generator Configuration Menu, coolant temperature will
be considered for cooldown. The generator will enter
cooldown when the start signal is removed, only if in
AUTO. The engine will run until the coolant temperature
is below the Engine Cooled Down parameter setting, or
until the Cooldown Delay has expired.
The cooldown cycle lasts for some predetermined
amount of time. The cooldown delay is an adjustable
parameter. The Engine Cooled Down temperature is
not adjustable.
Note: No engine cooldown cycle occurs if the OFF
button is pressed or if a fault occurs.
