Smartgen HGM190HC Genset Controller

The Model HGM190hc is an Automatic Engine Control Module. The module is used to automatically start and stop the engine, indicating the operational status and fault conditions, automatically shutting down the engine and indicating the engine failure by LED on the front panel.
Operation
If you use hgm190 for the first time, configure is necessary. If you want to configure the module, please look Configuration.Operation of the module is via a three position key switch mounted on the front panel with OFF (O), START and AUTO positions. In the ‘O’ position the output are de-energized.
Manual Operation:
1. Select manual run
2. Depress pre-heat button for required length of time
3. Press START to crank engine
Once the Start button is pressed and maintained, the engine fuel system is energized. The ‘Crank’ output is then energized and the starter motor operated, disengaging automatically when the engine fires or when the ‘Start’ button is released. The protection hold-off timer is then initiated.
Automatic Operation:
1. Select AUTO
2. When Remote Start is active, the generator will automatic start.
Operation of any of the following alarms (which are close on fault) will cause the run output to de-energize:
. Low Oil Pressure
. High Engine Temperature
. Auxiliary Shutdown
. Over speed
This will remove the fuel supply from the engine and bring it to rest. Each alarm has its own LED indicator and once activated no further alarm conditions will be accepted. The alarm output and relevant LED will remain active until the unit is reset by turning the switch to the ‘O’ position.
Over speed Protection
Over speed protection is derived from magnetic pickup sensor. Over 114% of rated speed will shutdown the engine. During engine cranking and for a short time afterwards the protection hold-off timer (10 seconds) is active and the relevant alarm inputs are inhibited. This enables the engine to start and achieve normal running conditions. Once the timer has expired the inputs are enabled providing normal protection from the module.
Charge Failure warning
Charge Failure warning is also provided by monitoring the WL terminal on the charge alternator. This operates on a similar principal to the warning lamp fitted in a motor vehicle, should the output fail the charge fail LED will illuminate. The module will also provide the alternator excitation current via this connection.
