6. Operating Instructions

Once correctly installed, the brushless controller will manage the power delivery to your electric bicycle or scooter motor based on your throttle input and other connected sensors (e.g., brake levers, pedal assist sensor if applicable).

• Power On: Turn on the electric door lock (ignition) to power the controller.
• Throttle Control: Use the speed control handle (throttle) to regulate motor speed.
• Braking: Activating the brake levers will cut power to the motor and engage braking.
• Gear Selection: If a 3-gear switch is connected, use it to select different speed modes (e.g., low, medium, high).
• Cruise Control: If connected and supported, activate cruise control via its dedicated switch.

7. Maintenance

To ensure the longevity and optimal performance of your brushless controller, follow these maintenance guidelines:

• Keep Clean: Regularly wipe the controller's exterior with a dry cloth to remove dust and dirt.
• Avoid Moisture: Protect the controller from direct exposure to rain, splashes, or high humidity.
• Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
• Avoid Overheating: Ensure the controller is mounted in a location with adequate airflow to prevent overheating during prolonged use.
• No Disassembly: Do not attempt to disassemble the controller for cleaning or repair, as this can cause damage and void the warranty.

8. Troubleshooting

If you encounter issues with your controller, refer to the following common troubleshooting steps:

• No Power:
  • Check the main power supply connection and battery charge level.
  • Ensure the electric door lock (ignition) is properly engaged.
  • Verify the power supply cord connections (red and black coarse wires).
• Motor Not Responding:
  • Check the throttle (speed control handle) connections.
  • Inspect motor phase and Hall sensor connections for looseness or damage.
  • Ensure brake levers are not engaged, as they cut motor power.
• Erratic Operation:
  • Verify all connections are secure and free from shorts.
  • Check for any signs of physical damage to the controller or wiring.

If the problem persists after performing these checks, it is recommended to consult a qualified technician or contact customer support.
