5. MODES OF OPERATION
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 TEST mode, if the REMOTE START
signal is not present then the genset will stop.
OFF:
If this mode is selected the engine will be stopped immediately.
AUTO:
It is used for the automatic genset operation. If the REMOTE START signal arrives, the engine 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.
Any of the spare digital outputs can be programmed as the generator contactor signal.
When the REMOTE START signal goes off, the engine will continue to run for the mains waiting period.
At the end of this period the generator contactor is deactivated. 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 REMOTE START signal.
If the operation of the genset is disabled by the WEEKLY SCHEDULE,
then the AUTO led will flash, and the genset operates as in the OFF
mode.
TEST:
It is used to run the genset when the REMOTE START signal is off, or keep the generator running
in the emergency backup mode. The operation of the generator is similar to the AUTO mode. If the
REMOTE START signal arrives, the generator contactor will be activated. If the REMOTE START signal
goes off, the generator contactor will release, but the engine will run until another mode is selected. To
stop the engine, select
AUTO
or
OFF
mode.
