5. Installation and Setup
5.1 Compatibility Check (Crucial Step)
Before installation, it is critical to verify the LCD Display protocol compatibility with your e-bike's controller. Different e-bike brands may use different protocols. Failure to match the protocol may result in the display not functioning correctly with your e-bike.
To ensure compatibility, locate the model number and protocol information on the back of your existing display (if replacing) or consult your e-bike's manufacturer specifications. If unsure, contact the seller with this information for verification.
5.2 Mounting the Display
- Choose a suitable position on your e-bike's handlebar, typically near the left grip, that allows for easy viewing and access to buttons without obstructing your riding.
- Loosen the clamp screws on the back of the display unit.
- Position the display on the handlebar and tighten the screws securely. Ensure the display is stable and does not rotate during use.
5.3 Electrical Connection
- Ensure your e-bike's power is OFF before making any electrical connections.
- Locate the corresponding cable from your e-bike's controller designed for display connection.
- Connect the 5-pin connector from the YL61F display to the matching port on your e-bike's wiring harness. Ensure the connection is firm and correctly oriented.
- Once connected, ensure all cables are neatly routed and secured to prevent snagging or damage during riding.
6. Operation
6.1 Power On/Off
- To Power On: Press and hold the power key (usually marked with a power symbol) on the display. The instrument will start, and the e-bike's controller will be powered on.
- To Power Off: In the power-on state, press and hold the power key again to turn off the electric vehicle's power supply. When shut down, the display consumes less than 1uA of current.
- Automatic Shutdown: If the e-bike is not used for more than 10 minutes, the display will automatically shut down to conserve battery power.
6.2 Basic Functions
- Assisted Gear Adjustment (PAS Level): Use the '+' and '-' buttons to increase or decrease the pedal assist level. The current level will be indicated on the display.
- Headlight Control: A dedicated button or a combination of buttons (refer to specific e-bike controller manual if not obvious) can be used to turn the headlights on or off. The display will show an indicator when headlights are active.
- Walk Boost: This function provides low-speed assistance for walking the e-bike. Typically activated by holding the '-' button or a specific combination.
- Viewing Data: The display continuously shows battery level, current speed, and PAS level. Other data like trip mileage, total mileage, max speed, and average speed can usually be cycled through by short-pressing the power button or a dedicated 'MODE' button (if present).
6.3 Parameter Settings
The YL61F allows for personalized parameter settings. Accessing these settings typically involves a specific button sequence (e.g., holding '+' and '-' simultaneously for a few seconds while powered on). Once in the settings menu, use the '+' and '-' buttons to navigate and adjust values, and the power button to confirm or move to the next setting.
Common adjustable parameters include:
- Wheel Diameter: Essential for accurate speed and mileage readings. Set this to match your e-bike's wheel size.
- Speed Limit: Adjust the maximum assisted speed according to local regulations and personal preference.
- Rated Voltage: Set to match your e-bike's battery voltage (36V or 48V).
- Power Sensor Magnets: Configure based on your e-bike's pedal assist sensor.
- Mileage Unit: Switch between Metric (Km/h, Km) and Imperial (Mile/h, Mile).
- Controller Current Limit: Adjust the maximum current supplied to the motor.
- Factory Default Restoration: Option to reset all parameters to their original factory settings.
Refer to your e-bike's main controller manual for specific instructions on accessing and adjusting advanced parameters, as the exact method can vary.
7. Maintenance
- Cleaning: Use a soft, damp cloth to wipe the display screen and body. Avoid abrasive cleaners or solvents that could damage the plastic or screen.
- Environmental Protection: Do not expose the display to prolonged direct sunlight, heavy rain, or extreme temperatures.
- Connection Check: Periodically check that the electrical connector is clean, dry, and securely attached.
- Storage: If storing your e-bike for an extended period, ensure the display is powered off.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display does not power on | Loose connection, low e-bike battery, incompatible protocol. | Check all cable connections. Ensure e-bike battery is charged. Verify display protocol compatibility with your controller. |
| Incorrect speed/mileage readings | Incorrect wheel diameter setting. | Access parameter settings and adjust the wheel diameter to match your e-bike's wheel size. |
| Display shows an error code | Indicates a specific issue with the e-bike system (motor, controller, sensor, etc.). | Note the error code displayed. Consult your e-bike's main manual or contact technical support with the code for diagnosis. |
| Buttons unresponsive | Dirt/debris, internal fault. | Clean around buttons. If problem persists, contact support. |
User Tips:
- Always double-check the display protocol with the seller or your e-bike manufacturer before purchasing to ensure compatibility. This is the most common reason for non-functionality.
- Keep a record of your personalized parameter settings in case a factory reset is needed.
- If you are unsure about any installation or setting adjustments, seek professional assistance.
