Key terminal groups include:

  • Terminals 1-20: DC power input, fuel output, crank output, charger output, auxiliary outputs, sensor inputs (oil pressure, engine temp, fuel level), magnetic pickup, ECU, and RS485 communication.
  • Terminals 21-24: Auxiliary inputs.
  • Terminals 25-28: Generator AC voltage inputs (U, V, W, N).
  • Terminals 29-32: Mains AC voltage inputs (R, S, T, N1).
  • Terminals 33-36: Current transformer (CT) inputs (IA, IB, IC, ICOM).

4. Setup and Installation

Careful installation and wiring are crucial for the correct operation of the HGM4020N controller. Refer to the wiring diagram provided with your product for specific connections. The following steps outline a general installation procedure:

  1. Mounting: Install the controller into a suitable panel cutout, ensuring adequate ventilation and protection from environmental factors. Secure it using the provided mounting clips.
  2. DC Power Supply: Connect the DC power supply (typically 8-35V DC) to the designated terminals (e.g., B+ and B-). Ensure correct polarity and adequate fusing.
  3. Generator AC Voltage Input: Connect the generator's three-phase or single-phase AC voltage outputs to terminals 25-28 (U, V, W, N).
  4. Mains AC Voltage Input (for AMF): If using the Automatic Mains Failure function, connect the utility (mains) AC voltage to terminals 29-32 (R, S, T, N1).
  5. Current Transformer (CT) Connections: Connect the secondary windings of the current transformers to terminals 33-36 (IA, IB, IC, ICOM) for current measurement. Ensure correct phasing.
  6. Engine Sensors: Connect engine sensors such as oil pressure, engine temperature, and fuel level to their respective input terminals (e.g., 10, 11, 12, 13).
  7. Engine Control Outputs: Connect the fuel solenoid, crank motor, and other auxiliary outputs to terminals 3-9 as per your generator's requirements.
  8. Communication: If remote monitoring is desired, connect the RS485 communication lines to terminals 18-20.
  9. Final Checks: Double-check all wiring for correctness, security, and insulation before applying power.

5. Operating Instructions

The HGM4020N controller offers both manual and automatic operation modes.

5.1 Manual Operation

  • Start: Press the Manual button, then the Start button. The controller will initiate the cranking sequence.
  • Stop: Press the Stop button. The generator will shut down.

5.2 Automatic Operation (AMF Mode)

In AMF mode, the controller monitors the mains power supply. If the mains power fails or falls outside acceptable limits, the controller will automatically start the generator. When mains power is restored, the controller will transfer the load back to the mains and shut down the generator after a cooling period.

  • Press the Auto button to enable automatic mode.
  • The controller will continuously monitor the mains supply.
  • Upon mains failure, the generator will start automatically.
  • Upon mains restoration, the generator will stop automatically after a cool-down period.

5.3 Parameter Viewing

Use the navigation buttons on the front panel to scroll through various generator parameters displayed on the LCD screen, such as voltage, current, frequency, engine speed, oil pressure, and engine temperature.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your HGM4020N controller.

  • Cleaning: Keep the controller's surface clean and free from dust. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
  • Connections: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can lead to intermittent operation or damage.
  • Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
  • Firmware: Consult the manufacturer or authorized service center for information on firmware updates.
