Automatic Start-Stop Operation of Generator Set Control Panel
An automatic start-stop system is used when an engine
must start with no one in attendance.
To start the engine when unattended, the ambient
(engine room) temperature must be at least 70F (20°C)
or, the engine jacket water temperature must be at least
90F (32C).
One or two 3kw jacket water heaters can maintain this
temperature.
In the AUTO. position, the engine will automatically start
and take up the load when remote starting contacts are
dosed. When used together with an automatic transfer
switch, the engine can be signaled to start and the load
automatically transferred when commercial power fails.
The automatic transfer switch will also remove the load,
cool and stop the engine.
If the unit is used for standby application with a remote
transfer switch, place the Engine Control Selector switch
in the AUTO. position, and adjust speed for proper
operation of the generator with load after starting.
When in the AUTO. position, the engine will
automatically stop if commercial power has been
restored or if the engine has a fault. The optional cool
down timer will allow engine to idle before shutting down.
Placing the Engine Control Selector in the STOP
position will stop the engine.
Overcranking
A timer allows the engine to crank either once for 30
seconds, or through 5 ten-second cranking cycles (de-
pending upon the device used) while unattended.
If the engine does not start before the time has elapsed,
the cranking motor will shut off, the overcrank light will
come on.
