HGM1780 Automatic Genset Controller
●
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 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; 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 normal operation 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 is deactivated.
In case of fault alarm, pressing and holding the button for one second will clear
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.
