expired. The alarm type of F/V Fault is block which means users can restart the generator only when
the alarm is acknowledged;
f)
If the on-load requirement has been achieved (Generator normal light will illuminate), the shaft genset
will close and synchronize automatically after pressing the
button;
g)
It will judge whether the SG power can meet receiving all the DG power when closing in load receiving
mode. If not, the controller will initiates an alarm and stop the closing operation. If it meets the
requirements, the DG will open and stop after all the loads are received by the SG (DG is effective in
auto mode); In a fixed power mode, the controller synchronously closes and operates at a fixed power
and grid connection with DG;
h)
If there is trip alarm occurs, then the system will open switch and the alarm information will be
displayed on the LCD.
Semi-auto Stop
：
a)
Press open button
in close status or input port of DG with load is effective, the system will
dispatch the DG starting ( DG is effective in auto mode), judging whether DG power will meet receiving
all the SG power, if not, controller will initiate an alarm and stop operations, if it meets the
requirements, soft unloading transferred and opened by SG first;
b)
After breaker opened or in breaker open status, press stop button
, system will enter into
“Stop Output Delay” while the stop relay will activate;
c)
After “Stop Output Delay”, system will enter into “Wait for Stop” delay. If genset voltage and frequency
signals disappeared during the delay, controller will judge that the genset stopped and in standby
state; otherwise, if genset voltage and frequency signals still can be detected after the delay expired,
controller will judge that the genset failed to stop;
d)
After genset failed to stop, if voltage and frequency signals are disappeared, controller will judge that
the genset stopped completely and entered into standby state.

When DG is loaded, SG will start and close automatically when the input of SG is effective with load, and
DG will automatically unload and stop;
When SG is loaded, DG will start and close automaticlly when the input of DG is effective with load, and SG
will automaticlly unload and stop;
In fixed power mode, SG will automatically start and connect to the grid with DG when the input of SG is
effective with load;
In load sharing mode, SG will automatically start and connect to the grid with DG when the input of SG is
effective with load;
