The generator set is waiting for a start signal. The
generator set will start and run when a start signal is
received via a remote start signal or a local start signal.
The generator set will start when it receives a start
signal. If the generator set is not in Auto mode, it will not
start.
When the start signal is removed, the generator set will
continue to run through the engine cooldown cycle, and
then shut down.
Idle Mode
If the generator set is equipped with an idle mode switch
across contacts 5 and 6, the engine can operate in idle
mode. When the idle mode switch closes, the engine
runs at low speed (1000 RPM) for 5 minutes and then
ramps up to normal speed and voltage. Idle Mode is
displayed in the status message area on the controller
screen. When the idle mode switch opens, the engine
runs through the cooldown cycle and then shuts down.
The controller must be in Auto mode for idle mode
operation.
