HGM6510 GENSET PARALLEL UNIT
genset will take load; generator power indicator will illuminate and generator will enter
into Normal Running status. if voltage or frequency is abnormal, the controller will
initiate shutdown alarm (alarm information will be displayed on LCD).
9. In case of running in parallel, after the warming up delay:
a) If bus has no voltage, then the controller will send a closing signal to other waiting
parallel gensets and generator close relay will activate, this prevents other sets in the
system from attempting to close their own breakers at the same time.
b) If bus has voltage or other gensets are already closed, the controller will adjust speed
and voltage through GOV and AVR to synchronize the gensets to the bus; when
synchronism requirements has been achieved, breaker close signal will be initiated
and the genset will be paralleled with the bus. Once they are paralleled, the controller
will control the generator to gradually accelerate and share load with other paralleled
gensets.
Automatic Stop Sequence,
1)
When the “Remote Start” signal is removed, the Stop Delay is initiated.
2)
Once this “stop delay” has expired, the module will ramp the load from the generator
to remaining set. The Generator Breaker will open and the “Cooling Delay” is then
initiated. Should the Remote Start signal be re-activated during the cooling down
period, the set will return parallel status. Once the “Cooling Delay” expires, the “Stop
Idle” delay is initiated.
3)
During “Stop Idle” Delay (if configured), idle relay is energized. If the unit has been
configured for CAN Bus, stop command can be carried out via CAN Bus;
4)
“ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized.
5) "Fail to Stop Delay" begins, complete stop is detected automatically.
6) Generator is placed into its standby mode after its complete stop. Otherwise, fail to
stop alarm is initiated and the corresponding alarm information is displayed on LCD.
5.2 MANUAL OPERATION (MULTIPLE SETS)
1. Manual mode is selected by pressing the button; a LED besides the button will
illuminate to confirm the operation; then press button to start the gen-set;
2.
Preheat relay energizes (if configured), “preheat delay XX s” information will be
displayed on LCD;
3. After the above delay, the Fuel Relay (or ECU output if configured) is energised, and
then one second later, the Start Relay is engaged. The engine is cranked for a pre-
set time. If the engine fails to fire during this cranking attempt then the fuel relay and
start relay are disengaged for the pre-
set rest period; “crank rest time” begins and
wait for the next crank attempt.
