that are in AUTO, will start and run. If the generator sets
were already running, they will remain running but the
original source of that start signal will be ignored. The
contacts now have control.
Stop Signal
A stop signal includes the following:
Removal of start signal via contacts 3 and 4. An ATS
D
(used during a power outage, exercise period, etc.) or
a remote panel used in the vessel take precedence
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. NOTE: This will not do anything if the
system start is not active. Press AUTO and OFF on
any controller in the system.
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 the engine control switch is
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 the
engine control switch is 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.

generator set is not in the AUTO mode.
Note: The transient start/stop function of the controller
prevents accidental cranking of the rotating engine.
The generator set stops and recranks when the
OFF/RESET button is momentarily pressed and
then the RUN button is pressed.
Note: The controller provides up to 30 seconds of
programmable cyclic cranking and up to
60 seconds rest with up to 6 cycles. The default
setting is 15 seconds cranking and 15 seconds
rest for 3 cycles. Make cyclic cranking
adjustments using SiteTecht software.
