Operating Instructions

Once correctly installed, the XINMEILAN 72V 50A controller will manage the power delivery from your scooter's battery to the motors, based on your throttle input and other control signals (e.g., brake levers, display settings). The controller operates automatically to provide smooth acceleration and efficient power usage.

• Power On/Off: Use your scooter's main power switch to turn the system on or off.
• Throttle Control: The controller translates your throttle input into motor power. Apply throttle smoothly for controlled acceleration.
• Braking: The controller integrates with your scooter's braking system, potentially offering regenerative braking or cutting motor power upon brake activation.
• Display Integration: The controller communicates with your scooter's display to show speed, battery level, and other operational parameters.

Maintenance

Proper maintenance ensures the longevity and reliable performance of your controller.

• Regular Inspection: Periodically inspect the controller and its wiring for any signs of wear, damage, or loose connections.
• Cleanliness: Keep the controller free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Avoid using liquids directly on the controller.
• Moisture Protection: Ensure the controller remains dry. If it gets wet, allow it to dry completely before operating the scooter.
• Temperature Management: Ensure adequate airflow around the controller, especially during prolonged use, to prevent overheating.

Troubleshooting

If you encounter issues with your controller, refer to the following common troubleshooting steps. For complex problems, consult a professional technician.

• No Power:
  • Check battery connection and charge level.
  • Verify main power switch is on.
  • Inspect power cables for damage or loose connections.
• Motor Not Responding:
  • Check throttle connection and functionality.
  • Inspect motor phase wires and hall sensor wires for secure connections.
  • Ensure brake levers are not engaged (some scooters cut power when brakes are applied).
• Erratic Behavior:
  • Check all wiring for loose connections or signs of short circuits.
  • Ensure the controller is not exposed to excessive heat or moisture.
• Error Codes on Display: Refer to your scooter's specific display manual for interpretation of error codes.
