Clear users' accumulation
It can clear accumulated running time A and B, accumulated electric energy A and B.
Main/Redundancy Controller (Not for HGM9510N)
It is optional as to whether main controller is active or redundancy controller is active.
4.4 AUTO START/STOP OPERATION
Press the
button and the indicator beside is illuminated, which means the genset is at Auto Start
Mode.
Automatic Start Sequence:
1)
When remote start (on-load) is active, "start delay" timer is initiated;
2)
"Start Delay" countdown will be displayed on genset status page;
3)
When start delay is over, preheating relay is energized (if configured), "preheat delay XX s"
information will be displayed on genset status page;
4)
After the above delay, the fuel relay is energized, and then one second later, the starting relay is
engaged. During the "start time", if the genset does not start, then fuel relay and starting relay stops
outputting, and enter "crank rest time", waiting for next crank;
5)
Should the start beyond the set attempts, the controller issues "start failure" and stops the genset
and at the same time alarm page on LCD displays "start failure alarm";
6)
If it starts during the attempts, it enters "safety on time", and during this period low oil pressure,
high temperature, under speed and charge alternator failure alarms are all inactive; After "safety on
time", it enters "start idle delay" (if configured);
7)
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);
8)
When single genset is running and "warming up delay" is over, 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; the genset will take load and generator power
indicator will be illuminated, and generator will enter normal running status. If voltage or frequency
is abnormal, the controller will initiate alarm (alarm information will be displayed on LCD);
9)
When the gensets is running in parallel and warming up delay is over:
a) If bus has no voltage signal, then the controller will issue a close status signal to other gensets
waiting for combination in parallel. Then generator close relay will output, avoiding to close the
breaker 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 synchronization
requirements have 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.
NOTE: When remote start is applied to start (off load), the procedure is the same as the above. But generator close
relay is deactivated, and moreover, genset is off load. When remote start is used to start, the genset will start based on
the set priority sequence, and then synchronize, put them in parallel and share the load in the bus automatically.
Automatic Stop Sequence:
When the remote start signal is removed, the "stop delay" is initiated;
1)
Once this "stop delay" has expired, the controller will ramp the load from the generator to other
2)
