Overview
HSC940 genset controllers integrate digitization, intellectualization and network technology which are used for gas genset automation and monitor control system of single unit to achieve automatic start/stop, data measure, alarm protection, three remote: remote control, remote
measuring and remote communication (SG485 module must be tted)
and speed regulation. The controller adopts large liquid crystal display
(LCD) and selectable Chinese, English, Spanish and Russian interface with easy and reliable operation.
HSC940 genset controllers adopt microprocessor technology with
precision parameters measuring, xed value adjustment, time setting and set adjusting etc. All parameters can be congured from front panel, or by congurable port (USB to LINK, SG72 must be tted) to adjust via PC. It can be widely used in all types of automatic genset control system
with compact structure, advanced circuits, simple connections and high
reliability.

Operation
4.3 AUTO START/STOP OPERATION
Auto mode is selected by pressing the button; a LED besides the button will illuminate to conrm 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 congured), “preheat delay XX s” information will be displayed on LCD;
4. After the above delay, the Fuel Relay is energized, and then one second later, the throttle of the driving stepper motor will rotate as the pre-set angle and then the Start Relay is engaged. The engine is cranked for a pre-set time. If the engine fails to re 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 fourth 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 and the throttle of
the driving stepper motor will govern the speed, allowing Low Oil Pressure, High Temperature,
Under speed, Charge Alternator Failure and auxiliary inputs (be congured) to stabilise without triggering the fault. As soon as this delay is over, “start idle” delay is initiated (if congured).
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 congured).
8. 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).
Automatic Stop Sequence:
1. When the “Remote Start” signal is removed, the Stop Delay is initiated.
2. Once this “stop delay” has expired, the Generator Breaker will open and the “Cooling Delay” is
then initiated. Moreover, the generator indicator is extinguished.
3. During “Stop Idle” Delay (if congured), idle relay is energized.
4. “ETS Solenoid Hold” delay begins, ETS relay is energized while fuel relay is de-energized.
5. "Fail to Stop Delay" begins, complete stop is detected automatically.
6. When generator is stop completely, generator is placed into its standby mode. Otherwise, fail
to stop alarm is initiated and the corresponding alarm information is displayed on LCD.

Operation
4.4 MANUAL START/STOP OPERATION
1. MANUAL START: Manual mode is selected by pressing the button; a LED besides the button will illuminate to conrm the operation.
Then press button to start the genset; 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.3~8 of Automatic Start Sequence for detail procedures.) The controller will send Close Gen signal after the
genset is normal running.
2. MANUAL STOP: Press can stop the running generators. (please refer to No.2~6 of Automatic Stop Sequence for detail procedures).

displayed on the LCD.
When the controller detects that the charger voltage has fallen below the pre-set value, it will initiate a warning alarm and the alarm information will be displayed on the LCD.
When the controller detects that the battery voltage has fallen below the pre-set value, it will initiate a warning alarm and the alarm information will be displayed on the LCD.
When the controller detects that the battery voltage has exceeded the pre-set value, it will initiate a warning alarm and the alarm information will be displayed on the LCD.
When the digit input port is set as warning and active, it will initiate a
warning alarm and the alarm information will be displayed on the LCD.
When the controller detects the speed is 0 and the Loss of Speed Signal delay is set as 0, it will initiate a warning alarm and the alarm information
will be displayed on the LCD.
When the controller detects that there is Low Coolant Level input, it will
initiate a warning alarm and the alarm information will be displayed on
the LCD. When the controller detects that there is Low Fuel Level input, it will
initiate a warning alarm and the alarm information will be displayed on
the LCD.

tiate a shutdown alarm and the alarm information will be displayed on the
LCD. When the controller detects that there is High Temperature input and the
shutdown is allowed, it will initiate a shutdown alarm and the alarm infor-
mation will be displayed on the LCD.
When the controller detects that there is Low Oil Pressure input and the shutdown is allowed, it will initiate a shutdown alarm and the alarm infor-
mation will be displayed on the LCD. When the controller detects that the generator speed has exceeded the pre-
set value, it will initiate a shutdown alarm and the alarm information will be
displayed on the LCD.
When the controller detects that the generator speed has fallen below the pre-set value, it will initiate a shutdown alarm and the alarm information will be displayed on the LCD.
When the controller detects the speed is 0 and the Loss of Speed Signal
delay is NOT set as 0, it will initiate a shutdown alarm and the alarm infor­mation will be displayed on the LCD.
When the controller detects that the generator voltage has exceeded the
pre-set value, it will initiate a shutdown alarm and the alarm information will be displayed on the LCD.
When the controller detects that the generator voltage has fallen below the pre-set value, it will initiate a shutdown alarm and the alarm information will be displayed on the LCD.
If the engine does not re after the pre-set number of attempts, it will initiate a shutdown alarm and the alarm information will be displayed on the
LCD. When the controller detects that the generator frequency has exceeded the
pre-set value, it will initiate a shutdown alarm and the alarm information will be displayed on the LCD.
When the controller detects that the generator frequency has fallen below the pre-set value, it will initiate a shutdown alarm and the alarm informa­tion will be displayed on the LCD.
