1 OVERVIEW
HGM9510 controller is designed for manual/auto parallel system generators with similar or
different capacity. Additionally, it is suitable for single unit constant power output and mains
paralleling. It allows automatic start/stop, parallel running, data measurement, alarm protection as
well as remote control, remote measurement and remote communication function. It fit with LCD
display, optional Chinese, English and other languages interface, and it is reliable and easy to
use.
Utilizing the GOV (Engine Speed Governor) and AVR (Automatic Voltage Regulator) control
function, the controller is able to synchronize and share load automatically; it can be used to
parallel with other HGM9510 controller.
HGM9510 controller also monitors the engine, indicating the operational status and fault
conditions accurately. When abnormal condition occurs, it splits bus and shuts down the genset,
simultaneously the exact failure mode information is indicated by the LCD display on the front
panel. SAE J1939 interface enables the controller to communicate with various ECU (ENGINE
CONTROL UNIT) which fitted with J1939 interface.
The powerful 32-bit Microprocessor contained within the module allows for precision parameters
measuring, fixed value adjustment, time setting and set value adjusting and etc..Majority
parameters can be configured from front panel, and all parameters can be configured by USB
interface (or RS485) to adjust via PC. It can be widely used in all types of automatic gen-set
control system with compact structure, advanced circuits, simple connections and high reliability.

5.4AUTO 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” is active, “Start Delay” timer is initiated;
2. “Start Delay” countdown will be displayed on LCD;
3. When start delay is over, preheat relay energizes (if configured), “preheat delay XX s”
information will be displayed on LCD;
4. After the above delay, the Fuel Relay (if configured) is energized, and then one second later,
the Start Relay is engaged. The engine is cranked for a pre-set time. If the engine fails to fire
during this cranking attempt then the fuel relay and start relay are disengaged for the pre-set
rest period; “crank rest time” begins and wait for the next crank attempt.
5. 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.
6. 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).
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. 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. In case of running 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 with the bus. Once they are paralleled, the controller will control the generator to
gradually accelerate and share load with other paralleled gensets.

HGM9510 GENSET PARALLEL UNIT
HGM9510 Genset Parallel Unit ISSUE 2013-08-06 Version 1.1Page 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.
5.5MANUAL 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.
5.6SWITCH 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.

Closing Operation：During genset normal running, press if generator voltage and frequency
have reached on-load requirements
1) In case of single unit running, generator closing relay outputs;
2) In case of running in parallel:
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.
Opening operation：Press ,
1) In case of single unit running, the controller sends open breaker signal.
2) During parallel operation, if button is pressed, first of all, the controller will transfer load
to other generators, and only then send an opening signal.
5.6.2 AUTOMATIC CONTROL PROCEDURE
When controller is in auto mode, the switch control procedure is automatic control procedure.
Note：The auxiliary close input should be configured necessarily and make sure the
connection is correct.

6 PROTECTIONS
6.1WARNING ALARMS
Warnings are not shutdown alarms and do not affect the operation of the gen-set. Warning alarms
does not lead to shutdown. Warning alarms types are as follows:
No

the pre-set value and the action select “Warn”, it will initiate a
warning alarm.
15
Over Power
If over power detection is enabled, when the controller detects that
the over power value (power is positive) has exceeded the pre-set
value and the action select “Warn”, it will initiate a warning alarm.
16
