4. Operating Instructions

The CHENHO Electric Bike Controller is designed for intuitive operation, providing smooth and responsive control for your electric bike or scooter.

Basic Operation:

1. Power On: Ensure all connections are secure and turn on your e-bike/scooter's main power switch.

3. Pedal Assist System (PAS): If connected, the PAS will provide motor assistance based on your pedaling input.
4. Braking: Apply the brake levers. The low-level brake input will cut off motor power, and the E-brake system will engage if connected.

Safety Features:

• Low-Voltage Protection: The controller includes protection at DC 30/40±0.5V to prevent battery over-discharge, extending battery life.
• Responsive Braking: The low-brake input ensures immediate motor power cut-off upon braking for enhanced safety.

5. Maintenance

The CHENHO Electric Bike Controller is designed for durability with its aluminum and reinforced plastic construction. Regular maintenance will help ensure its longevity and optimal performance.

• Keep Clean: Periodically wipe the controller's exterior with a dry cloth to remove dust and dirt. Avoid using harsh chemicals or excessive moisture.
• Check Connections: Regularly inspect all wiring connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or component failure.
• Avoid Overheating: Ensure the controller is mounted in a location with adequate airflow to prevent overheating, especially during prolonged high-power usage.
• Protect from Water: While durable, avoid submerging the controller in water or exposing it to heavy rain for extended periods.
