5.2 Speed and PAS (Pedal Assist System) Adjustment

The controller supports 5 adjustable gear levels, which can be controlled through a compatible meter (display). The PAS system also features 5 gears, allowing for varied levels of pedal assistance.

5.3 Regenerative Braking Function

This controller includes a regenerative braking function. When braking, the motor generates electricity, which is then fed back to the battery. This not only helps to recharge the battery but also assists in achieving a quicker braking effect, reducing the burden on mechanical brakes.

5.4 Speed Limit and Reversing Function

The controller supports a speed limit function, typically set at 25 KM/H via a dedicated plug. It also includes a reversing function for added utility.

6. Maintenance

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

• Cleaning: Keep the controller clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
• Water Protection: While the controller has an IP65 waterproof rating, meaning it is protected against dust ingress and low-pressure water jets, avoid submerging it in water or exposing it to high-pressure water streams.
• Heat Dissipation: Ensure the controller's heat sink fins are not obstructed to allow for proper heat dissipation. Good airflow around the controller is essential, especially during prolonged use.
• Cable Inspection: Periodically inspect all connected cables and connectors for any signs of wear, damage, or loose connections. Secure any loose connections immediately.

7. Troubleshooting

This section addresses common issues you might encounter with your controller.

• No Power/Controller Not Responding:
  • Check all power connections from the battery to the controller.
  • Verify battery voltage is within the rated range (36V-72V).
  • Ensure the low voltage alarm is not active, indicating a low battery.
• Motor Not Spinning/Irregular Operation:
  • Confirm all motor phase wires and Hall sensor wires are correctly connected.
  • Check throttle connection and functionality.
  • If using a display, ensure it is compatible and properly connected.
• Difficulty with Parameter Setting:
  • Ensure the USB data cable is securely connected to both the controller and your device (mobile phone/computer).
  • Verify that the correct software/app is installed and running on your device.
• Overheating:
  • Check for obstructions around the controller that might impede airflow.
  • Ensure the controller is mounted in a location with adequate ventilation.

For issues not covered here, please refer to the official support channels or consult a professional.
