HGM6510 GENSET PARALLEL UNIT
NOTE: If the unit has been configured for CAN Bus, compatible ECU‟s will
receive the start command via CAN Bus.
4. Should this start sequence continue beyond the set number of attempts, the start
sequence will be terminated, the first line of LCD display will be highlighted with black
and Fail to Start fault will be displayed.
5. In case of successful crank attempt,
the “Safety On” timer is activated, allowing Low
Oil Pressure, High Temperature, Under speed and Charge Alternator Failure inputs
to stabilise without triggering the fault. As soon as this delay is over, “start idle” delay
is initiated (if configured).
NOTE: If the unit has been configured for CAN Bus, speed sensing is via CAN
Bus.
6.
During “start idle” delay, under speed, under frequency, under voltage alarms are
inhibited. When this delay is over, “warming up” delay is initiated (if configured).
7.
When “warming up” delay is over, the genset waits for taking load;
8.
Press button, in the case of a single generator system, after the “warming up”
delay, if generator status is normal, its indicator will be illuminated. If generator
voltage and frequency have reached on-load requirements, then the generator close
relay will be energized; 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. If the
button is pressed while 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 to the bus. Once they are paralleled, the controller
will control the generator to gradually accelerate and share load with other paralleled
gensets.
10. If the
button is pressed while in parallel operation, the module will ramp the load
on the remaining generators and then open the generator breaker.
