4. Models and Types

The HGM4000N series controllers are available in several types, each with specific functionalities:

• HGM4010N/HGM4010NC/HGM4010CAN: These are Automatic Start Modules (ASM). They control the generator to start and stop based on a remote signal.
• HGM4020N/HGM4020NC/HGM4020CAN: These models feature Automatic Mains Failure (AMF) functionality. They build upon the HGM4010 series by adding mains electric quantity monitoring and automatic transfer control between mains and generator, ideal for systems involving both generator and utility power.

5. Setup and Installation

Proper installation is crucial for the reliable operation of the HGM4020 controller. Ensure all connections are secure and follow local electrical codes. The controller is designed for panel mounting.

5.1. Mounting

The controller requires an installation dimension of 116mm x 90mm. Secure the unit firmly into the control panel cutout using the provided mounting hardware.

5.2. Wiring Connections

Refer to the wiring diagrams on the back of the unit for correct connections. Ensure the working power range of DC(8-35)V is supplied. Connect all necessary inputs (e.g., mains voltage, generator voltage, current, oil pressure, water temperature) and outputs (e.g., fuel, crank, auxiliary outputs) according to your system's requirements.

6. Operating Instructions

6.1. Power On/Off

Ensure all wiring is correct before applying power. The controller will perform a self-test upon power-up. To power off, disconnect the DC supply.

6.2. Control Modes

• Stop Mode: The generator is off and will not start automatically.
• Auto Mode: The generator will automatically start and stop based on configured parameters (e.g., mains failure for HGM4020 models, remote start signal for HGM4010 models).
• Manual Mode: Allows for manual starting and stopping of the generator using the front panel buttons.

6.3. Parameter Configuration

Parameters such as start/stop delays, alarm thresholds, and engine protection settings can be adjusted via the front panel buttons and LCD menu, or through a PC connected via USB or RS485 interface using the Smartgen configuration software.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of the HGM4020 controller. Keep the unit clean and free from dust and moisture. Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure the operating environment remains within the specified temperature range of -25°C to +70°C.

8. Troubleshooting

If the controller is not functioning as expected, consider the following general troubleshooting steps:

• No Power: Check the DC power supply (8-35V) and all power connections.
• Generator Fails to Start: Verify the control mode (ensure it's in Auto or Manual start mode). Check fuel levels, battery voltage, and engine protection alarms.
• Alarm Indication: Refer to the alarm messages on the LCD display. Consult the detailed alarm codes in the full product manual for specific remedies.
• Incorrect Readings: Check sensor connections and calibration settings.
