How can I activate the remote start function on the Smartgen HGM6120CAN controller if my board only has motor protection and no city power input?

To activate the remote start function on your Smartgen HGM6120CAN controller, you should utilize the auxiliary input terminals. According to the manual, the controller supports configurable digital inputs for remote start operations.Wiring: Connect your remote start signal to one of the Auxiliary Input terminals. You will need to refer to the wiring diagram on the back of the unit to identify which terminal is designated for digital inputs.Configuration: You must enter the controller's programming mode (which may require a password) to configure that specific auxiliary input as a "Remote Start" trigger.Operating Mode: Ensure the controller is set to Auto Mode by pressing the Auto button on the front panel. In this mode, the controller will wait for a signal from the remote start input to initiate the generator start sequence.Since you mentioned your board does not have city power (mains) input, the controller will function as a remote start module rather than an Automatic Mains Failure (AMF) module. Ensure that your engine sensors (oil pressure, water temperature) are correctly wired to the analog inputs so the controller can still provide the motor protection you require during the remote start cycle.

LCD Display: Shows generator parameters, alarms, and operational status.
Navigation Buttons: Used to scroll through menus and adjust settings (Up, Down, Left, Right, OK).
Manual Button: Puts the controller in manual mode for direct control.
Auto Button: Puts the controller in automatic mode for AMF operation.
Start Button: Initiates generator start sequence (in Manual mode).
Stop Button: Initiates generator stop sequence.

2. Operating Modes

Manual Mode:
Press the Manual button. In this mode, the generator can be started and stopped manually using the Start and Stop buttons. Load transfer is also manual.
Auto Mode:
Press the Auto button. The controller will automatically monitor the mains supply. If the mains fail, the controller will initiate the generator start sequence, transfer load, and stop the generator when mains power is restored.

3. Parameter Viewing and Configuration

Use the navigation buttons to scroll through the various display screens to view generator parameters, engine status, and alarm logs. Configuration of parameters requires entering the programming mode, typically protected by a password. Refer to the detailed programming manual for specific parameter settings.

Maintenance

Regular maintenance ensures the longevity and reliable operation of the HGM6120CAN controller and the generator set.

Cleaning: Periodically clean the controller's front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Connections: Annually check all wiring connections for tightness and signs of corrosion. Loose connections can lead to intermittent operation or damage.
Firmware Updates: Check the manufacturer's website for any available firmware updates. Updates can improve performance or add new features.
Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.

Troubleshooting

This section provides basic troubleshooting steps for common issues. For complex problems, consult a qualified technician or the manufacturer's support.

Problem	Possible Cause	Solution
Controller display is blank.	No DC power supply; Blown fuse; Loose power connection.	Check DC power input (8V-35V); Inspect and replace fuse; Secure power connections.
Generator fails to start in Auto mode.	Mains power present; Auto mode not selected; Engine fault (low oil, high temp); Fuel issue.	Verify mains status; Ensure Auto mode is active; Check engine parameters and alarms; Verify fuel level.
Generator starts but does not take load.	Load transfer inhibited; Circuit breaker tripped; Generator output fault.	Check load transfer settings; Reset circuit breakers; Inspect generator output.
Alarm indication on display.	Specific fault detected (e.g., overspeed, low oil pressure).	Note the alarm code/message; Refer to the detailed manual for alarm definitions and corrective actions.
