4.4 AUTO START/STOP OPERATION
Auto mode is selected by pressing the button; a LED besides the button will illuminate to confirm the
operation.
Automatic Start Sequence:
1. When remote start (on-load) input is active or mains is abnormal, “Start Delay” timer is initiated; “Start
Delay” countdown will be displayed on LCD;
2. When start delay is over, the controller will issue a start command, “Start Request XXs” information will be
displayed on LCD;
3. Any available 9560 in auto mode will be issued with a start signal. Please refer to the 9510 operating
manual for further details of the start sequence.
4. Once the Minimum number of sets have synchronized onto the bus, the 9560 will enter into normal
running:
a) If mains switch didn’t close, then bus close relay activate.
b) If mains switch already closed, the controller will adjust speed and voltage to synchronize bus with mains;
when synchronism requirements has been achieved, bus close signal will be initiated and the bus will be
paralleled with the mains. Once the bus has synchronized to the mains, the power will be ramped off the
bus.
5. If the number of the synchronized set is less than the Minimum number after the “Start Request” delay is
over, then the “Too Few Modules” alarm will be initiated.
Note: When started via “Remote Start (off Load)” input, same procedures as above but bus close relay
deactivated, moreover, bus off load. When started via “Remote Start (Demand)” input，same procedures as
above if the start requirements has been achieved (e.g. when the load has exceed the set value in shave
lopping mode).
Automatic Stop Sequence,
1) When the “Remote Start” signal is removed, and moreover, mains is normal, the Stop Delay is initiated.
2) Once this “stop delay” has expired,
a) If mains switch didn’t close, then bus open relay activate.
b) If mains switch already closed, first of all, the controller will transfer load to mains, and only then bus open
relay activate.

HGM9560 Bus Tie Mains Parallel Unit Page 15 of 47
3) The controller will issue a stop command and the genset is in “At Rest” mode.
4) Any available 9560 in auto mode will be issued with a stop signal. Please refer to the 9510 operating
manual for further details of the stop sequence.
4.5 MANUAL START/STOP OPERATION
Manual mode is selected by pressing the button; a LED besides the button will illuminate to confirm
the operation.
Manual Start Operation:
1. Press button to start the genset, the controller will issue a start command, “Start Request XXs”
information will be displayed on LCD;
2. Any available 9560 in auto mode will be issued with a start signal. Please refer to the 9510 operating manual
for further details of the start sequence.
3. Once the Minimum number of sets have synchronized onto the bus, the 9560 will enter into normal
running:
4. If the number of the synchronized set is less than the Minimum number after the “Start Request” delay is
over, then the “Too Few Modules” alarm will be initiated.
Manual Transfer Procedures
Bus Close Operation: During genset is normal running, press Bus Close Button :
1) If mains switch didn’t close, then bus close relay activate.
2) If mains switch already closed, the controller will adjust speed and voltage to synchronize bus with mains;
when synchronism requirements has been achieved, bus close signal will be initiated and the bus will be
paralleled with the mains. Once the bus has synchronized to the mains, the power will be ramped off the
mains.
Bus Open Operation：Press Bus Open Button :
1) If mains switch didn’t close, then bus open relay activate.
2) If mains switch already closed, first of all, the controller will transfer load to mains, and only then bus open
relay activate.
Mains Close Operation: During mains is in normal status, press Mains Close Button :
1) If bus switch didn’t close, then mains close relay activate.
2) If bus switch already closed, the controller will adjust speed and voltage to synchronize bus with mains;
when synchronism requirements has been achieved, mains close signal will be initiated and the mains will
be paralleled with the bus. Once the mains has synchronised to the bus, the power will be ramped off the
bus.

HGM9560 Bus Tie Mains Parallel Unit Page 16 of 47
Mains Open Operation：Press mains Open Button :
1) If mains switch didn’t close, then mains open relay activate.
2) If mains switch already closed, first of all, the controller will transfer load to bus, and only then mains open
relay activate.
Manual Stop Operation:
1) Stop mode is selected by pressing the button; a LED besides the button will illuminate to
confirm the operation:
a) If mains switch didn’t close, then bus open relay activate.
b) If mains switch already closed, first of all, the controller will transfer load to mains, and only then bus open
relay activate.
2) The controller will issue a stop command and the genset is in “At Rest” mode.
3) Any available 9560 in auto mode will be issued with a stop signal. Please refer to the 9510 operating
manual for further details of the stop sequence.

HGM9560 Bus Tie Mains Parallel Unit Page 17 of 47
5MULTIPLE MAINS OPERATION
In a multiple mains system, the gensets are controlled by more than one 9560 mains controller and used to
provide power to multiple loads.
Should one or more of the mains supplies fail, the generators are started and supply power to the load. If more
than one mains supply has failed, the loads are transferred to the generators one by one.
If one mains supply returns, the 9560 connected to that mains supply will synchronies the generators with the
mains and affect a no-break changeover. The generators continue to supply power to the remaining loads.
If more than one mains supply returns at the same time, then the 9560 with the highest priority will take control
of the generators and affect a no-break changeover back to the mains supply.
HGM9560 priority fall into two types: status priority and module priority.
If status priorities are different, then the HGM9560 priority is up to the status priorities；
If status priorities are same, then the HGM9560 priority is up to the module priority；
The module priority can be set while the status priority can not.
