Setup and Installation
Proper installation is crucial for the controller's optimal performance and safety. Always refer to your specific vehicle's wiring diagram for detailed connection points. The following steps provide a general guide.
General Installation Steps:
- Disconnect Power: Before commencing any work, ensure the vehicle's battery is completely disconnected to prevent electrical hazards.
- Locate Mounting Position: Choose a secure, dry, and well-ventilated location on your vehicle for the controller. Ensure it is protected from direct impact and moisture.
- Mount Controller: Securely fasten the controller using appropriate screws or brackets. Ensure it is stable and will not vibrate loose during operation.
- Connect Motor Wires: Connect the three main motor phase wires (typically thick green, yellow, blue) from the controller to the corresponding motor wires. Ensure a tight and secure connection.
- Connect Hall Sensor Wires: Connect the Hall sensor wires (typically a smaller bundle of five wires: red, black, blue, green, yellow) from the controller to the motor's Hall sensor connector.
- Connect Power Wires: Connect the main positive (red) and negative (black) power wires from the controller to the battery terminals. Ensure correct polarity (+ to +, - to -) to avoid damage.
- Connect Ignition/Key Switch: Connect the ignition wire (often red or orange) to your vehicle's key switch or power lock.
- Connect Throttle: Connect the throttle wires (typically three wires: red, black, green/blue) to the throttle assembly.
- Connect Brake Levers: Connect the brake lever wires (often two wires per lever) to the controller's brake input. This ensures power cut-off when brakes are applied.
- Connect Other Accessories: Connect any other accessories such as lights, display, or alarm system according to your vehicle's specific wiring diagram.
- Double-Check Connections: Before reconnecting the battery, meticulously verify that all connections are tight, correctly matched, and properly insulated.
- Test Functionality: Reconnect the battery and perform a low-speed test in a safe environment to ensure all functions (throttle, brakes, motor rotation) are working correctly and smoothly.

Operating Instructions
Once correctly installed, operating the controller is straightforward as it automatically manages motor functions based on your throttle input and other vehicle controls.
Basic Operation:
- Power On: Turn the vehicle's key switch to the "ON" position. The vehicle's display (if equipped) should illuminate.
- Throttle Control: Gently twist the throttle grip to accelerate. The controller will smoothly deliver power to the motor, providing a responsive and quiet ride.
- Braking: Engage the brake levers to slow down or stop. The controller is designed to cut power to the motor when brakes are applied, enhancing safety.
- Power Off: Turn the key switch to the "OFF" position when you have finished riding or when the vehicle is not in use.
Note: The sine wave technology of this controller ensures a quiet and efficient ride, minimizing motor noise and maximizing battery life.
Maintenance
The XINMEILAN Sine Wave Controller is designed for durability and reliability, requiring minimal maintenance to ensure long-term performance.
- Regular Inspection: Periodically inspect all wiring connections for tightness, signs of wear, fraying, or corrosion. Address any issues promptly.
- Cleanliness: Keep the controller's exterior clean and free from dirt, dust, and moisture. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive materials.
- Avoid Overheating: Ensure the controller has adequate airflow, especially during prolonged use or in hot weather. Do not cover the controller or obstruct its heat fins.
- Storage: If the vehicle is to be stored for an extended period, ensure the battery is disconnected to prevent any potential drain or electrical issues.
Troubleshooting
This section provides solutions to common issues you might encounter. For problems not listed here, please contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not running | No power to controller, loose connections, faulty throttle, faulty motor Hall sensors, engaged brake lever. | Check battery connection, ignition switch, throttle wiring, motor Hall sensor connections, and ensure brake levers are not engaged. |
| Intermittent power or erratic motor behavior | Loose wiring connections, intermittent short circuit, damaged wiring. | Inspect all connections for looseness or damage. Ensure wires are not pinched or frayed. |
| Motor runs roughly or makes unusual noise | Incorrect motor phase wire connection, damaged motor, or internal controller issue. | Verify motor phase wire connections are correct. If the problem persists after checking connections, consult a qualified technician. |
