4. Setup and Installation

Careful installation is crucial for the proper functioning of the controller. Follow these steps:

4.1 Mounting

• Select a suitable location for mounting the controller, ensuring it is protected from direct sunlight, excessive vibration, and moisture.
• Ensure adequate ventilation around the unit.
• Mount the controller using the provided mounting hardware, ensuring it is firmly secured.

4.2 Wiring

Refer to the wiring diagram provided with your specific model (GU3311 or GU3310) for detailed connection instructions. General wiring considerations include:

• Power Supply: Connect the controller to a stable DC power source (typically 8-36V DC). Ensure correct polarity.
• Generator Voltage Inputs: Connect the generator's phase voltages (L1, L2, L3, N) to the designated terminals.
• Mains Voltage Inputs (if applicable): For automatic transfer switch (ATS) applications, connect the mains phase voltages.
• Current Transformer (CT) Inputs: Connect the secondary windings of the current transformers to the controller's CT input terminals. Ensure correct phasing.
• Engine Sensors: Connect engine sensors such as oil pressure, water temperature, fuel level, and speed sensor (magnetic pickup) to their respective inputs.
• Output Relays: Connect the starter motor, fuel solenoid, and other control devices to the configurable output relays.
• Emergency Stop: Wire the emergency stop button to the dedicated input.

After all connections are made, double-check all wiring for correctness and security before applying power.

5. Operating Instructions

The controller offers various operating modes to suit different applications.

5.1 Control Modes

• Manual Mode: In this mode, the generator is started and stopped manually using the front panel buttons. This mode is typically used for testing or specific operational requirements.
• Auto Mode: The controller automatically starts and stops the generator based on predefined conditions, such as mains failure, remote start signal, or scheduled events.
• Stop Mode: The generator is stopped and remains off. All automatic functions are disabled.

5.2 Starting the Generator

• In Manual Mode: Press the Start button (usually green). The controller will initiate the starting sequence, including pre-heat (if configured) and cranking.
• In Auto Mode: Ensure the controller is in Auto mode. The generator will start automatically when a valid start condition is met (e.g., mains failure).

5.3 Stopping the Generator

• In Manual Mode: Press the Stop button (usually red). The controller will initiate the stopping sequence.
• In Auto Mode: The generator will stop automatically when the start condition is no longer met (e.g., mains restored) and after a cool-down period.

5.4 Monitoring Parameters

The LCD display shows various engine and generator parameters. Use the navigation buttons to scroll through different screens to view:

• Generator Voltage (L-N, L-L)
• Generator Current
• Frequency
• Engine Speed (RPM)
• Oil Pressure
• Coolant Temperature
• Battery Voltage
• Run Hours

6. Maintenance

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

• Cleaning: Periodically clean the controller's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no dust accumulates on the display or buttons.
• Connection Checks: Annually, or as needed, inspect 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. Follow the provided instructions carefully for any update procedures.
• Battery Check: Ensure the generator's starting battery is in good condition and properly charged, as this directly affects the controller's ability to start the engine.

7. Troubleshooting

This section provides solutions to common issues you might encounter.

• Controller Does Not Power On:
  • Check the DC power supply voltage and connections.
  • Verify the battery voltage is within the specified range.
• Generator Fails to Start:
  • Check fuel level and ensure the fuel solenoid is functioning.
  • Verify engine battery charge and connections.
  • Check for active alarms on the controller display that might be preventing start.
  • Ensure the controller is in the correct operating mode (Manual or Auto with a valid start signal).
• Generator Starts but Shuts Down Immediately:
  • Check for active protection alarms (e.g., low oil pressure, high coolant temperature, overspeed).
  • Verify sensor connections and functionality.
• Incorrect Readings on Display:
  • Check sensor wiring and calibration settings.
  • For voltage/current, verify CT connections and ratios are correctly configured.

If the issue persists after following these steps, contact technical support.
