5. Installation Guide
Before beginning installation, ensure the vehicle's power is completely off and the battery is disconnected.
5.1 Controller Installation
- Select a suitable location for the controller, preferably in a protected area with good airflow to aid in heat dissipation.
- Securely mount the controller using appropriate fasteners.
- Connect the main power cables (typically a yellow XT60 connector for battery input) to your battery.
- Connect the three thick motor phase wires (blue, green, yellow) from the controller to the corresponding motor wires.
- Connect any additional accessory wires such as throttle, brake levers, and other sensors as required by your e-bike/scooter system. Refer to the general wiring diagram below for common connections.
5.2 Display Unit Installation
- Mount the JH-01 LCD Display Unit onto your handlebar using the integrated clamp. Ensure it is positioned for easy viewing and access to buttons.
- Connect the 6-pin connector cable from the display unit to the corresponding port on the brushless motor controller.
5.3 General Wiring Connections
While a specific wiring diagram is not provided, typical connections for a brushless controller and display unit include:
- Battery Power: Connect the main power wires (often red/black, with a high-current connector like XT60) to your battery.
- Motor Phase Wires: Connect the three thick wires (blue, green, yellow) to the corresponding motor phase wires.
- Display Unit: Connect the 6-pin cable from the JH-01 display to the dedicated display port on the controller.
- Throttle: Connect the throttle signal wire (usually green or white), power (red), and ground (black) to the throttle input on the controller.
- Brake Levers: Connect brake lever cut-off switches (if present) to the controller. This system supports electronic braking.
- Other Accessories: Connect any other accessories such as lights or horn to their respective ports on the controller, if available.
6. Operating Instructions
6.1 Powering On/Off
- To power on the system, press and hold the Power button (
) on the JH-01 display unit for a few seconds until the screen illuminates. - To power off, press and hold the Power button again until the display turns off.
6.2 Display Functions
The JH-01 LCD display provides essential information about your ride:
- Speed: Current riding speed.
- Battery Level: Indication of remaining battery charge.
- Mode: Current riding mode or power assist level.
- Other Data: May include trip distance, total distance, error codes, etc., depending on the specific display firmware.
6.3 Mode Selection
Use the MODE button on the display unit to:
- Cycle through different display information (e.g., ODO, TRIP, Voltage).
- Adjust power assist levels (if applicable to your system).
- Access basic settings (refer to specific display instructions if available for advanced settings).
7. Maintenance
- Cleaning: Keep the controller and display unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Connections: Periodically check all electrical connections to ensure they are secure and free from corrosion.
- Physical Inspection: Inspect the controller and display for any signs of physical damage, such as cracks, dents, or frayed wires. Address any damage promptly.
- Environmental Protection: While the controller is durable, avoid prolonged exposure to extreme temperatures, direct sunlight, or heavy rain.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on | Disconnected battery, low battery charge, faulty power button, loose display connection. | Check battery connection and charge level. Ensure the 6-pin display cable is securely connected. Try pressing the power button firmly. |
| Motor not responding | Loose motor phase wires, faulty throttle, controller issue. | Verify all three motor phase wires are securely connected. Check throttle connection. Ensure the controller is receiving power. Note: This controller is designed for sensorless motors. |
| Display not showing information | Loose 6-pin display connection, display unit fault. | Ensure the 6-pin cable connecting the display to the controller is firmly seated. |
| Electronic brake not working | Brake lever sensor disconnected or faulty, controller issue. | Check connections from brake levers to the controller. Ensure brake levers are functioning correctly. |
9. User Tips
- Compatibility Check: Always ensure that the JH-01 display and the 36V 19A controller are compatible with your specific electric scooter or e-bike model before installation. Using mismatched components can lead to malfunction.
- Sensorless Operation: This controller is designed for motors without Hall sensors. If your motor has Hall sensors, ensure it can operate in sensorless mode or consider a different controller.
- Waterproofing Connections: For outdoor use, consider adding extra waterproofing (e.g., electrical tape or sealant) to exposed wire connections to protect against moisture ingress.
- Cable Management: Route all cables neatly and secure them to prevent snagging or damage during operation.
