4.2 Initial Power-Up

After all connections are verified, apply DC power to the controller. The LCD screen should illuminate, and the controller will perform a self-test. Follow the on-screen prompts or refer to the detailed programming manual for initial configuration settings.

5. Operating Instructions

The HGM6120N controller supports both manual and automatic operation modes.

5.1 Manual Mode

• Press the Manual button to enter manual mode.
• Press the Start button to manually start the generator.
• Press the Stop button to manually stop the generator.

5.2 Auto Mode (AMF)

• Press the Auto button to activate automatic mains failure mode.
• In this mode, the controller continuously monitors the mains power supply.
• If mains power fails or falls outside preset parameters, the controller will automatically initiate the generator start sequence.
• Once mains power is restored and stable, the controller will automatically transfer the load back to the mains and shut down the generator after a cooling period.

5.3 Parameter Monitoring

The LCD display provides real-time data. Use the navigation buttons (up/down arrows) to scroll through various parameters such as:

• Generator Voltage (L-L, L-N)
• Generator Frequency (Hz)
• Generator Current (A)
• Generator Power (kW, kVA, kVAr)
• Engine Speed (RPM)
• Battery Voltage (V)
• Engine Oil Pressure
• Engine Temperature
• Fuel Level
• Mains Voltage (L-L, L-N)
• Mains Frequency (Hz)

6. Maintenance

The HGM6120N controller is designed for minimal maintenance. However, regular checks can ensure its longevity and reliable operation.

• Visual Inspection: Periodically inspect the controller for any signs of physical damage, loose connections, or corrosion.
• Cleaning: Keep the controller's surface clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Firmware Updates: Check the manufacturer's website for any available firmware updates that may improve performance or add features.
• Battery Check: Ensure the generator's battery, which powers the controller, is in good condition and properly charged.
