6. Setup and Installation
Before beginning installation, ensure the power source is disconnected. The controller features various color-coded wires for different functions. Refer to the diagram below and your vehicle's wiring schematic for precise connections.
Image 1: Silscvtt 24-36V 500W Brushless Motor Speed Square Wave Controller with its array of connection wires.
Typical Wiring Connections:
- Battery Connection: Connect the thick red wire to the positive (+) terminal of your 24-36V battery and the thick black wire to the negative (-) terminal.
- Motor Connection: Connect the three thick motor phase wires (typically yellow, green, blue) from the controller to the corresponding motor phase wires.
- Hall Sensor Wires (if applicable): Connect the thinner Hall sensor wires (typically red, black, yellow, green, blue) from the controller to the motor's Hall sensor wires. If your motor is Hall-sensorless, these wires may not be used.
- Throttle Connection: Connect the throttle wires (typically red, black, green) to the corresponding throttle input on the controller.
- Brake Lever Connection: Connect the brake lever wires (High/Low Electrical Level) to the designated brake input on the controller.
- Ignition/Power Lock: Connect the ignition wire (often red, labeled 'Door Lock' or similar) to your vehicle's power switch. This acts as the main power on/off for the controller.
- Self-Learning Wires (Automatic Identification): The controller features 60° / 120° automatic identification. To utilize this, connect the two self-learning wires (often white or blue, usually labeled 'Self-Study' or similar) together briefly after all other connections are made and power is applied. The motor will spin slowly. Once the motor runs smoothly, disconnect these wires. This process helps the controller adapt to your motor's phase angle.
- Other Connections: Connect any additional wires for features like speed display, cruise control, or alarm systems as per your vehicle's requirements and the controller's labeling.

After all connections are made, double-check them for correctness and security before applying full power.
7. Operating Instructions
- Power On: Turn on the main power switch of your e-bike or scooter. The controller will initialize.
- Throttle Control: Gently twist the throttle to accelerate. The controller provides sensitive speed control.
- Braking: Apply the brake levers to slow down or stop. The controller will cut off motor power upon brake activation.
- Automatic Identification: If you performed the self-learning procedure during setup, the controller will automatically adapt to your motor's phase angle for optimal performance.
- Power Off: Turn off the main power switch when the vehicle is not in use.
8. Maintenance
- Keep the controller clean and free from dust and debris.
- Regularly inspect all wire connections for tightness and signs of wear or corrosion.
- Ensure the controller's aluminum casing is not obstructed to allow for proper heat dissipation.
- Avoid harsh impacts or dropping the controller.
- Do not use harsh chemicals or solvents for cleaning; a soft, dry cloth is sufficient.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not run | No power to controller; Loose connections; Faulty throttle; Faulty motor Hall sensors. | Check battery connection and voltage; Verify all wiring is secure; Test throttle functionality; Check motor Hall sensor wires or try running in Hall-sensorless mode if supported. |
| Motor runs intermittently or roughly | Incorrect phase angle identification; Loose motor phase wires or Hall sensor wires. | Perform the self-learning procedure again; Check all motor and Hall sensor connections. |
| Controller gets excessively hot | Overload; Insufficient ventilation. | Reduce load on the motor; Ensure controller is mounted in a well-ventilated area; Check for short circuits. |
| Brakes do not cut motor power | Brake lever switch faulty; Brake signal wire disconnected. | Test brake lever switch; Check brake signal wire connection to controller. |
If problems persist after attempting these solutions, please contact customer support.
