The modes of operation are selected by pressing the front panel keys.
OFF:
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 generator 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 wait period. When the engine runs, the
crank relay will be immediately deactivated. After the G phase voltage is within the limits, 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 mains
contactor will be energized. If a cooling period is given, the generator will continue to run during
cooling 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.
TEST:
It is used to test the generator when the mains are on, or keep the generator waiting 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 is kept running. In order to
stop the engine, push the OFF button.
DISPLAY TEST:

OFF and TEST buttons are pressed together and deselected when no button is pressed.
