The modes of operation are selected by pushing the front panel keys. Changing the operation

mode while the genset is running will result into a behavior suitable for the new operating mode. For
example, if the AUTO mode is selected when genset is running at RUN mode, if mains phase voltages
are present then the genset will stop.

STOP:

In this mode, the mains contactor will be energized if mains phase voltages are within the

programmed limits. The engine will be stopped.

AUTO:

It is used for genset and mains automatic transfer. If at least one of the mains phase voltages is

outside limits, the mains contactor will be deactivated.
The diesel will be started for programmed times after the preheat timer. When the engine runs, the crank
relay will be immediately deactivated. The engine will run without load during engine heating period. After
this, if alternator phase voltages and frequency are within limits, then the unit will wait for the generator
contactor period and the generator contactor will be energized.
When all the mains phase voltages are within the limits, the engine will continue to run for the mains
waiting period. At the end of this period the generator contactor is deactivated and the mains contactor will
be energized. If a cooldown period is given, the generator will continue to run during cooldown period. At
the end of the period, the fuel solenoid will be de-energized and the diesel will stop. The unit will be ready
for the next mains failure.

RUN:

It is used to test the generator when the mains are on, or keep the generator running in the

emergency backup mode. The operation of the generator is similar to the AUTO mode, but the mains
contactor will not be deactivated if the mains are not off. If the mains are off, mains contactor will be
deactivated and the generator contactor will be activated. When the mains are on again, a changeover to
the mains will be made, but the engine will be kept running unless another mode is selected. To stop the
engine, select

AUTO

or

STOP

mode.

The unit offers the possibility of

REMOTE START

mode of operation. Any digital input may be

assigned as

Remote Start Input

using

Input Function Select

program parameters.

The REMOTE START signal may be a NO or NC contact, switching to either battery positive or

battery negative. These selections are made using programming menu.

It is also necessary to set the

ACTION

program parameter of the related input to

3

in order to

prevent any alarm from this input.

In this mode the mains phases are not monitored. If the REMOTE START signal is present

then the mains will be supposed to fail, inversely if the REMOTE START signal is absent, then mains
voltages will be supposed to be present.
