1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of the NYUMMRYT HGM6120CAN Smartgen Diesel Generator Controller. The HGM6120CAN is an advanced module designed for automatic start/stop control, data measurement, alarm protection, and 'three remote' (remote control, remote measurement, remote communication) functions for diesel generator sets. It supports AMF (Automatic Mains Failure) functionality, allowing for automatic transfer between mains and generator power. This controller is equipped with R485 and CAN communication interfaces for enhanced system integration.

2. Product Overview

The HGM6120CAN controller is a robust and reliable solution for managing diesel generator operations. Its key features include:

• Automatic Mains Failure (AMF) functionality.
• Automatic start/stop control for generator sets.
• Comprehensive data measurement and display.
• Multiple alarm protection functions.
• Equipped with R485 communication interface.
• Supports CAN communication for engine ECU integration.
• User-friendly interface with LCD display and push buttons.

The front panel features an LCD screen for displaying operational parameters and alarms, along with buttons for navigation, mode selection (Auto/Manual), and start/stop commands. The rear panel provides all necessary connection terminals for power, sensors, actuators, and communication interfaces.

3. Setup and Installation

Proper installation is crucial for the reliable operation of the HGM6120CAN controller. Refer to the wiring diagram on the rear panel (Figure 2.2) for all connections.

3.1 Mounting

Mount the controller in a secure, vibration-free location, typically within a control panel. Ensure adequate ventilation and protection from moisture and extreme temperatures.

3.2 Wiring Connections

All wiring should be performed by qualified personnel, adhering to local electrical codes and safety standards. Ensure all power is disconnected before making any connections.

• Power Supply: Connect the DC power supply (B+ and B-) to terminals 1 and 2.
• Emergency Stop: Connect the emergency stop button to terminal 3.
• Crank/Start: Connect the engine crank/start signal to terminal 4.
• Fuel Solenoid: Connect the fuel solenoid to terminal 5.
• Auxiliary Outputs: Utilize auxiliary outputs (terminals 6-14) for various control functions such as pre-heat, common alarm, etc., as per your system requirements.
• Sensor Inputs: Connect engine sensors (magnetic pickup, engine temperature, oil pressure, fuel level) to terminals 15-20.
• Auxiliary Inputs: Connect auxiliary inputs (terminals 21-22, 38-40) for external signals or alarms.
• Gens Voltage & Mains Voltage: Connect generator voltage (U, V, W, N) to terminals 27-30 and mains voltage (R, S, T, N1) to terminals 31-34.
• RS485 Communication: Connect RS485 A and B lines to terminals 35 and 36 respectively for remote monitoring and control.
• CAN Communication: Connect CAN SCR, CAN H, and CAN L to terminals 41-43 for communication with CAN-enabled engines (ECU J1939).
• Current Transformer (CT) Inputs: Connect CTs for current measurement to terminals 23-26.

4. Operating Instructions

The HGM6120CAN controller offers both automatic and manual operating modes.

4.1 Control Panel Overview

Familiarize yourself with the buttons and indicators on the front panel (refer to Figure 2.1).

• Auto Button: Selects Automatic mode. The generator will start/stop automatically based on mains power status.
• Manual Button: Selects Manual mode. Allows for manual control of the generator.
• Start Button: Initiates generator start sequence in Manual mode.
• Stop Button: Initiates generator stop sequence in Manual mode.
• Load/Genset/Mains Buttons: Control the load transfer switches.
• Up/Down/OK Buttons: Used for navigating menus and adjusting parameters on the LCD display.
• Alarm/Status Indicators: Provide visual feedback on the system's operational state and any active alarms.

4.2 Automatic Mode (AMF)

In Auto mode, the controller continuously monitors the mains power supply. If a mains failure is detected, the controller will automatically start the generator, transfer the load, and provide power. Upon restoration of mains power, the controller will transfer the load back to the mains and shut down the generator after a cool-down period.

1. Press the Auto button to activate Automatic mode. The Auto indicator will illuminate.
2. The controller will monitor mains voltage.
3. If mains power fails, the generator will automatically start after a pre-set delay.
4. Once the generator is stable, the load will be transferred to the generator.
5. When mains power returns, the load will be transferred back to the mains after a pre-set delay.
6. The generator will then enter a cool-down period and shut down.

4.3 Manual Mode

Manual mode allows for direct control over the generator's start and stop functions.

1. Press the Manual button to activate Manual mode. The Manual indicator will illuminate.
2. To start the generator, press the Start button.
3. To stop the generator, press the Stop button.
4. Load transfer can be manually controlled using the Load, Genset, and Mains buttons as required.

5. Maintenance

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

• Cleaning: Periodically clean the controller's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the display is clear of dust and debris.
• Connections Check: Annually inspect all wiring connections for tightness and signs of corrosion. Loose connections can lead to intermittent operation or damage.
• Environmental Inspection: Ensure the operating environment remains within specified temperature and humidity ranges. Protect the controller from direct sunlight, excessive dust, and moisture.
• Software Updates: Check the manufacturer's website for any available firmware updates that may improve performance or add new features.
