The included speed control knob allows for variable speed adjustment. It connects to the controller via a 2-plug, 6-wire configuration.
4. Setup and Installation
Follow these steps for proper installation of the controller and speed control knob:
- Mount the Controller: Securely mount the controller in a protected area on your vehicle, away from direct water exposure and excessive vibration.
- Connect Motor Phase Wires: Connect the three thick motor phase wires (typically green, yellow, blue) from the controller to the corresponding motor phase wires.
- Connect Hall Sensor Wires: Connect the smaller Hall sensor wires (typically five wires) from the controller to the motor's Hall sensor connector. Ensure correct color matching.
- Connect Battery Power: Connect the thick red wire from the controller to the battery's positive terminal and the thick black wire to the battery's negative terminal.
- Connect Throttle/Speed Control: Connect the speed control knob's wires to the throttle input on the controller. Refer to Image 3.1 for specific wire labels.
- Connect Brake Levers: Connect the brake lever wires to the controller's low-level or high-level brake inputs as required by your system.
- Connect Other Functions: Connect any other desired functions such as the 3-speed switch, intelligent recognition, key on/off switch, or anti-theft alarm according to the wiring diagram.
- Automatic Phase Identification: After all connections are made, power on the system. The controller will automatically identify the motor's phase angle (60°/120°). If the motor spins in the wrong direction, swap two of the motor phase wires and two of the Hall sensor wires (e.g., swap green and yellow).
- Test Operation: Carefully test the throttle and brake functions before full operation.
5. Operating Instructions
Once installed, operating the controller is straightforward:
- Power On: Turn on the vehicle's main power switch (if applicable) or the controller's key on/off switch.
- Speed Control: Use the speed control knob to adjust the motor's output speed. Turning the knob clockwise typically increases speed, while counter-clockwise decreases it.
- Braking: Engaging the brake levers will cut power to the motor, providing a safety stop.
- 3-Speed Switch (if connected): If a 3-speed switch is connected, it allows you to select between different preset speed modes (e.g., low, medium, high).
6. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your controller:
- Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can affect heat dissipation. Use a dry, soft cloth.
- Inspect Connections: Regularly check all wire connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or component failure.
- Avoid Water Exposure: While the controller is designed for outdoor use, avoid direct exposure to heavy rain or submersion in water. Ensure all cable glands are properly tightened.
- Temperature Management: Ensure the controller has adequate airflow for cooling. Avoid covering it with insulating materials during operation.
7. Troubleshooting
Refer to the table below for common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not run | No power to controller; Loose connections; Faulty throttle; Motor or Hall sensor issue. | Check battery connection and voltage; Verify all wiring is secure; Test throttle function; Inspect motor and Hall sensors. |
| Motor runs in reverse | Incorrect motor phase or Hall sensor wiring. | Swap two motor phase wires and two Hall sensor wires. |
| Intermittent power/speed | Loose connections; Damaged wiring; Overheating controller. | Check all connections; Inspect wiring for damage; Ensure adequate cooling for the controller. |
| Controller gets hot | Overload; Insufficient cooling; Short circuit. | Reduce load; Ensure proper ventilation; Check for short circuits in motor or wiring. |
