- Cable Inspection: Periodically check the display cable and connectors for any signs of wear, damage, or loose connections.
- Storage: When not in use for extended periods, store the e-bike in a dry, temperate environment.
8. Troubleshooting
If you encounter issues with your TF01U display, consider the following:
- Display Not Turning On:
- Check if the e-bike battery is charged and turned on.
- Ensure all connections between the display and the controller are secure.
- Verify that the display is compatible with your controller (must be a KT series controller).
- Incorrect Speed/Distance Readings:
- Check the wheel circumference setting in your controller's parameters (if adjustable via display or controller).
- Ensure the speed sensor is correctly installed and functioning.
- USB Charging Not Working:
- Ensure the display is powered on.
- Check the USB cable and the device being charged.
- Error Codes: If an error code appears on the display (e.g., 'ERROR 05' as seen in some images), consult your KT controller's manual for specific interpretations and solutions. These codes typically indicate issues with the motor, controller, or sensors.
9. User Tips
- Verify Controller Compatibility: Always double-check that your e-bike controller is a KT series model before purchasing or installing this display. This is the most common reason for incompatibility.
- Choose the Right Plug: Decide between the SM (normal) and WP (waterproof) plug versions based on your existing wiring and environmental conditions. The WP plug offers better protection against moisture.
- UART Protocol: The KT TF01U display communicates using the UART protocol, which is standard for KT controllers. Ensure your controller also supports this protocol for seamless integration.
