3. Setup and Installation
The JH4AZ2613DZQR controller is designed for integration into electric bicycle conversion kits. Due to the customizable nature of this product and the variety of e-bike setups, specific wiring diagrams and installation instructions may vary. It is highly recommended to consult with the seller and provide your e-bike's specifications immediately after placing your order to receive tailored guidance.
General installation steps typically involve connecting the controller to the motor, battery, throttle, brake levers, and display (if applicable). Ensure all connections are secure and correctly oriented to prevent damage.
3.1 Pre-Installation Checklist
- Verify the voltage compatibility of your battery and motor with the controller (DC48V).
- Ensure all components of your e-bike conversion kit are present and undamaged.
- Have appropriate tools ready (e.g., wire cutters, crimpers, electrical tape, multimeter).
- Disconnect the battery power before making any electrical connections.
3.2 Connection Overview (General)
- Motor Connection: Connect the motor phase wires (typically thicker, often green, blue, yellow) and Hall sensor wires (smaller, multi-pin connector) to the corresponding ports on the controller.
- Battery Connection: Connect the battery power cables (typically red for positive, black for negative) to the main power input of the controller. Ensure correct polarity.
- Throttle Connection: Connect the throttle cable to the designated throttle input on the controller.
- Brake Lever Connections: Connect the brake lever cut-off switches (if your system includes them) to the controller. The controller supports low-level brake signals.
- Display/Control Panel: If your kit includes a display or control panel, connect it to the appropriate communication port on the controller.
- Other Accessories: Connect any other accessories such as pedal-assist sensor (PAS), lights, or horn according to your kit's specific instructions.
Warning: Incorrect wiring can cause severe damage to the controller, motor, or battery, and may pose a safety risk. If you are unsure, seek professional assistance.
4. Operating Instructions
Once the controller is correctly installed and all connections are secure, follow these general operating procedures:
- Power On: Turn on the e-bike battery. If your system has a main power switch or display, activate it.
- Initial Check: Before riding, perform a quick check:
- Ensure the display (if present) powers on and shows correct information.
- Gently twist the throttle to confirm motor response.
- Test the brake levers to ensure the motor cuts off when brakes are applied.
- Riding: Use the throttle or pedal-assist system (if installed) to control the motor's power output. The controller will manage power delivery based on your input and the selected assist level (if applicable).
- Power Off: Always turn off the e-bike battery or main power switch when not in use to conserve battery life and prevent accidental activation.
5. Maintenance
Proper maintenance ensures the longevity and reliable performance of your JH4AZ2613DZQR controller:
- Keep Clean: Regularly clean the exterior of the controller to prevent dust and dirt buildup, which can affect heat dissipation. Use a dry, soft cloth.
- Inspect Connections: Periodically check all electrical connections for tightness and signs of corrosion or wear. Loose connections can lead to intermittent power or damage.
- Avoid Water Exposure: While the controller may have some water resistance, avoid submerging it or exposing it to heavy rain for extended periods. Ensure the casing is sealed properly.
- Temperature Management: Operate the controller within its specified working temperature range (-20℃ to 60℃). Avoid prolonged operation in extreme heat, which can lead to overheating.
- Storage: When storing the e-bike for extended periods, especially in cold conditions, ensure the storage temperature is within -30℃ to 70℃.
6. Troubleshooting
If you encounter issues with your JH4AZ2613DZQR controller, consider the following common troubleshooting steps:
