4.1 Safety Precautions
- Always disconnect the battery before performing any installation or maintenance.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Verify voltage compatibility (24V/36V/48V) with your e-bike system before connecting.
- Avoid exposing the controller to water or extreme temperatures.
4.2 Wiring Diagram Overview
The controller features a variety of connectors for different e-bike components. Refer to the image below for a visual guide to the common connectors. Specific wiring details may vary based on your e-bike kit and display (e.g., 2HAO Display).
4.3 General Installation Steps
- Mount the Controller: Securely mount the controller in a protected area on your e-bike, away from direct moisture and physical impact. Ensure adequate ventilation.
- Connect Motor Phase Wires: Connect the three thick wires from the controller to the corresponding motor phase wires (usually green, blue, yellow).
- Connect Hall Sensor Wires: Connect the smaller Hall sensor wires (typically 5 or 6 wires) from the controller to the motor's Hall sensor connector.
- Connect Battery: Connect the main power wires (red for positive, black for negative) from the controller to your e-bike battery. Double-check polarity.
- Connect Display (2HAO): Connect the display cable from the controller to your 2HAO display unit.
- Connect Throttle: Connect the throttle cable to the designated throttle input on the controller.
- Connect Brake Levers: Connect the brake lever cables (if applicable) to the controller's brake input. These typically cut power to the motor when brakes are applied.
- Connect Pedal Assist Sensor (PAS): If your e-bike has a PAS, connect its cable to the controller.
- Other Connections: Connect any other accessories such as lights, speed sensor, or cruise control if supported by your controller and e-bike system.
- Initial Test: After all connections are made, double-check them. Reconnect the battery and perform a low-power test to ensure the motor, throttle, and display function correctly before riding.
5. Operating Instructions
Once installed, the X098-AXC013 controller manages the power delivery to your e-bike motor based on your input from the throttle and pedal assist sensor, and information from the 2HAO display.
5.1 Powering On/Off
- To Power On: Turn on your e-bike battery, then press the power button on your 2HAO display. The display should illuminate, indicating the controller is active.
- To Power Off: Press and hold the power button on your 2HAO display until it turns off. Then, turn off your e-bike battery.
5.2 Using the Throttle
Gently twist the throttle to engage the motor. The amount of twist corresponds to the power output. Start slowly to get accustomed to the power delivery.
5.3 Pedal Assist System (PAS)
If your e-bike is equipped with a PAS, the controller will provide motor assistance as you pedal. The level of assistance is typically adjustable via your 2HAO display.
5.4 Display Functions (2HAO)
Your 2HAO display will show important information such as speed, battery level, assist level, and potentially trip distance. Refer to your 2HAO display's specific manual for detailed operation and settings adjustments.
6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your motor controller.
- Keep Clean and Dry: Regularly wipe down the controller housing with a dry cloth. Avoid using water or cleaning solutions directly on the unit.
- Inspect Connections: Periodically check all wiring connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent power or damage.
- Avoid Overheating: Ensure the controller has adequate airflow and is not covered, especially during prolonged use or in hot weather.
- Protect from Impact: While durable, avoid dropping or subjecting the controller to heavy impacts.
7. Troubleshooting
If you encounter issues with your X098-AXC013 controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not responding | Loose connections, low battery, faulty throttle/PAS, motor/controller issue. | Check all wiring connections. Ensure battery is charged. Test throttle/PAS if possible. If problem persists, consult a professional. |
| Display not turning on | Battery off, loose display cable, faulty display. | Ensure battery is on. Check display cable connection. Try another display if available. |
| Intermittent power | Loose battery connection, damaged wiring, overheating. | Secure battery connections. Inspect wiring for damage. Allow controller to cool down. |
| Motor runs rough/noisy | Incorrect motor/Hall sensor wiring, motor damage. | Double-check motor phase and Hall sensor connections. If wiring is correct, motor may be damaged. |
If you are unable to resolve an issue using the troubleshooting guide, please contact customer support.
8. User Tips
- Customization Confirmation: As this is a customizable product, always confirm your specific e-bike parameters with the seller immediately after purchase to ensure the controller is configured correctly for your system.
- Wiring Verification: Before powering on, meticulously verify all wiring connections, especially the battery polarity and motor phase/Hall sensor wires, to prevent damage.
