HGM9510 GENSET PARALLEL UNIT
HGM9510 Genset Parallel Unit ISSUE 2013-08-06 Version 1.1 Page 17 of 65
Note: When started via “Remote Start (off Load)” input, same procedures as above but
generator close relay deactivated, moreover, genset off load. When started via “Remote Start
(Demand)” input，the genset will start, synchronization, parallel and load sharing automatically
according to the pre-set priority order.
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.
4) “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized, complete
stop is detected automatically.
5) "Fail to Stop Delay" begins, complete stop is detected automatically.
6) When generator is stop completely, “After stop” delay will be initiated. Otherwise, fail to stop
alarm is initiated and the corresponding alarm information is displayed on LCD. ( If generator
is stop successfully after “fail to stop” alarm has initiated, “After stop” delay will be initiated and
the alarm will be removed)
7) Generator is placed into its standby mode after its “After stop” delay.
5.5 MANUAL START/STOP OPERATION
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; can detect crank
disconnect condition and generator accelerates to high-speed running automatically. With
high temperature, low oil pressure, over speed and abnormal voltage during generator
running, controller can protect genset to stop quickly (please refer to No.3~9 of Automatic
Start Sequence for detail procedures).
2. MANUAL STOP: Press can shuts down the running generators. (Please refer to
No.2~7 of Automatic Start Sequence for detail procedures).
NOTE: In “manual mode”, the procedures of ATS please refer to Switch Control Procedure of
generator in this manual.
5.6 SWITCH CONTROL PROCEDURES
5.6.1 MANUAL TRANSFER PROCEDURES
When controller is in Manual mode, the switch control procedures will start through manual
transfer procedures. Users can control the loading transfer of ATS via pressing button to switch
on or off.
