displays fault conditions and provides effective alarmsignals.

OVERVIEW

HGM1780 is a genset automatic start module with 3 working modes that can be

selected from the front panel. It can detect one-phase generator voltage and current,

can be started and stopped manually or via a remote start/stop signals. In case of

faults (such as low oil pressure, high water/cylinder temperature, emergency stop

alarm, over speed), HGM1780 can automatically disconnect fuel relay and close ETS

electromagnet to stop the generator. Graphical LCD monitor on the front panel

input is deactivated) and used as water pump unit controller;

◆

Running status and alarm status are indicated by red LED on thepanel;

◆

Compatibility with multiple temperature, pressure, fuel level sensors, which can

be user-defined and used directly; temperature sensors, pressure sensors can

be used in parallel with annunciator, providing digital data and increasing

protection level at the same time;

◆

Multiple crank disconnect conditions to select (engine speed sensor, oil pressure,

generator);

◆

2 fixed relay outputs (fuel relay, start relay);

◆

1 configurable output port which can be set as common alarm output, fail to stop

output, preheat output or idle control output;

◆

Parameters can be set and modified by users and saved in internal FLASH

storage, which means that they will not be lost in case of power off. All

parameters of the controller can be modified using the front panel or through

configurable LINK port via PC software (SG72 adapter, produced by our

company must be used). All parameters can be set via computer using one USB

port of the computer, which also allows to avoid batteries: power supply for the

controller can come directly from the PC USB port.

◆

HGM1780 combines modular design, anti-flaming ABS plastic case, embedded

installation, compact structure, small size, SCM control, stable performance and

convenient operation.

4.4. OPERATION INSTRUCTION

The module has three working modes: stop mode ( ), manual mode ( ) and auto

mode ( ).

●Manual Start ( )

After pressing Manual Start button ( ) and holding it for at least one second, the

indicator next to the button will be illuminated. Preheating output will be activated

firstly and preheat delay begins. One second before it is finished, fuel output will

be activated for one second and after that preheat output will be deactivated;

starter is energized to output and engine cranks. When generator frequency

reaches the pre-set value, the starter motor will be deactivated and generator will

start. Then, safety delay will start, after it is finished, idle delay will start, and when

it is finished idle relay will be closed and the generator will start working at normal

speed.

●Auto Mode ( )



After pressing and holding button for at least one second, the indicator next

to the button will be illuminated and the module will be placed into its automatic

mode. If remote start signal is active (remote start input port is connected to B-),

after start delay the genset will start. Preheating output will be activated firstlyand

preheat delay begins. One second before it is finished, fuel output will be

activated for one second and after that preheat output will be deactivated; then

starter is energized to output (engine will try to start according to the pre-set

number of times; if one of the attempts is successful, the start process will be

completed, otherwise fail to start alarm will be initiated: fail to start indicator on the

panel will be illuminated and common alarm indicator will flash). After start delay

and idle delay, idle relay will be deactivated and the generator will start working at

normal speed.

Note: During crank rest time, fuel output is deactivated; three seconds after the

beginning of the delay, preheat and ETS outputs will be activated; after the end

of the delay, ETS output will be deactivated and fuel relay output; preheat output

will be deactivated before the beginning of crank.



When remote start signal is deactivated, after stop delay, the generator enters idle

state and the idle relay is deactivated. After idle delay, fuel relay deactivates, ETS

relay output activates, and the genset automatically stops. After complete stop,

ETS relay deactivates.

●Stop ( )



After pressing and holding for at least one second during normaloperation of

the genset (in manual or auto modes), the light indicator near the button will be

illuminated and idle operation will begin. When idle relay deactivates and after idle

delay, fuel relay is deactivated and ETS output is energized. When complete stop

of the generator, ETS isdeactivated.



In case of fault alarm, pressing and holding the button for one second willclear

alarms. Holding it for more than one second will illuminate all indicators on the

panel (light test function).



Pressing this button for more than one second in stop mode will lead to activation

of ETS output and illumination of all the indicators on the panel (light test function).

Releasing the button will immediately deactivate ETS output and light test

function.



When in stop mode, the module will only react to emergency stopsignal.

Note: Configurable output ports can be set as one of the following functions: “ETS

output”, “Idle output” or “Preheat output” via PC. Therefore, all three functions can

not be active at the same time; the above-mentioned is only to describe the logical

course of action of the controller in case all three functions are active.
