3. Setup and Installation
Proper installation is crucial for the controller's functionality and safety. If you are unsure about any steps, consult a qualified technician.
- Safety First: Ensure the electric scooter's power is completely off and the battery is disconnected before beginning installation.
- Identify Components: Familiarize yourself with the various connectors on the controller. These typically include power input, motor phase wires, hall sensor wires, throttle input, brake signals, and display connections. Refer to Figure 3.1 for a visual guide to the controller's label and wiring.
- Mounting: Securely mount the controller in a protected area of the scooter, away from direct moisture and excessive heat. Ensure adequate ventilation.
- Wiring Connections:
- Connect the main power wires (red for positive, black for negative) to the battery.
- Connect the three motor phase wires (typically green, blue, yellow) to the corresponding motor wires.
- Connect the Hall sensor wires (usually a five-wire connector) to the motor's Hall sensor port.
- Connect the throttle, brake levers, and any display or light connections according to your scooter's wiring diagram.
- Ensure all connections are firm and insulated to prevent short circuits.
- Initial Test: After all connections are made, re-connect the battery. Perform a low-speed test in a safe, open area to verify proper motor function, throttle response, and brake operation.

4. Operating Instructions
Once installed, the controller operates automatically based on throttle input and other sensor data from your electric scooter.
- Power On: Turn on your electric scooter's main power switch. The controller will initialize.
- Throttle Control: Gently apply the throttle to accelerate. The controller will regulate power to the motor based on your input.
- Braking: Activating the brake levers will signal the controller to cut power to the motor, ensuring safe deceleration.
- Monitoring: Pay attention to any display indicators on your scooter for battery level, speed, and error codes.

5. Maintenance
The Brushless DC Controller is designed for durability, but regular checks can extend its lifespan and ensure optimal performance.
- Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can affect heat dissipation.
- Inspect Wiring: Regularly check all wiring connections for signs of wear, corrosion, or looseness. Secure any loose connections and replace damaged wires.
- Avoid Moisture: While the housing offers some protection, avoid exposing the controller to heavy rain or submersion in water.
- Temperature Management: Ensure the controller is not operating in excessively hot environments without adequate airflow. Overheating can damage internal components.
6. Troubleshooting
If you encounter issues with your electric scooter's motor performance, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not running | No power to controller; Loose wiring; Faulty throttle; Motor issue. | Check battery connection and charge; Inspect all wiring; Test throttle; Check motor for damage. |
| Motor runs intermittently | Loose Hall sensor wires; Intermittent power connection. | Secure Hall sensor connections; Verify stable power supply. |
| Reduced power/speed | Low battery charge; Overheating controller; Motor issues. | Charge battery fully; Allow controller to cool; Inspect motor. |
| Brakes not cutting power | Brake lever sensor disconnected or faulty. | Check brake lever wiring and functionality. |
If problems persist after attempting these solutions, contact customer support or a qualified technician.
