4. Specifications

Note: This product does not include an instrument display interface and cannot be used with external display instruments.

5. Setup and Installation

Careful installation is crucial for the proper functioning and longevity of your controller. Follow these general guidelines:

1. Preparation: Ensure the vehicle's power is completely off and the battery is disconnected before starting installation.
2. Mounting: Securely mount the controller in a location that allows for adequate airflow and heat dissipation. Utilize the integrated mounting brackets. Avoid areas prone to direct water exposure or excessive vibration.
3. Wire Identification: The controller comes with various color-coded wires and connectors. Refer to the wiring diagram provided with your motor or vehicle for specific connections. Common connections include:
   • Power Wires: Connect to the battery (usually thick red for positive, thick black for negative).
   • Motor Wires: Connect to the motor (usually three thick wires for phase, and thinner Hall sensor wires).
   • Throttle Wires: Connect to the throttle mechanism.
   • Brake Wires: Connect to the brake levers/sensors.
   • Other Function Wires: May include wires for speed sensor, cruise control, anti-theft, etc. Connect these according to your vehicle's specific requirements.
4. Connection: Carefully connect each wire, ensuring a firm and correct connection. Incorrect wiring can damage the controller, motor, or battery.
5. Insulation: After making connections, ensure all exposed wires and terminals are properly insulated to prevent short circuits and corrosion.
6. Initial Test: Once all connections are made, reconnect the battery and perform a low-power test to verify functionality before full operation.

6. Operating Instructions

The Haofy Brainpower Controller is designed for intuitive operation, providing smooth and efficient control over your electric vehicle.

• Power On: Once correctly installed and connected, turn on the main power switch of your electric bicycle or scooter. The controller will initialize.
• Speed Control: Use the throttle to control the motor speed. The sine controller technology ensures a consistent and steady speed output, providing a smooth acceleration and deceleration experience.
• Braking: The controller is designed for sensitive control of braking. When the brake levers are engaged, the controller will cut power to the motor, allowing for effective stopping.
• Silent Operation: Benefit from the sine controller's ability to operate seamlessly and silently, enhancing your riding experience without disruptive motor noise.
• Direction Changes: The controller facilitates precise control for changes in direction, contributing to a responsive and manageable ride.

7. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your controller.

• Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can hinder heat dissipation. Use a dry, soft cloth.
• Check Connections: Regularly inspect all wire connections for tightness and signs of corrosion or damage. Loose connections can lead to intermittent operation or component failure.
• Heat Dissipation: Ensure that the controller's mounting location remains clear of obstructions to allow for proper airflow and heat dissipation. Overheating can reduce the controller's lifespan.
• Avoid Moisture: While the casing offers some protection, avoid exposing the controller to heavy rain or direct water spray.
• Inspect Wires: Check wires for any cuts, abrasions, or signs of wear. Repair or replace damaged wires immediately.

8. Troubleshooting

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

• No Power to Motor:
  • Check battery charge level.
  • Verify all power connections (battery to controller) are secure.
  • Ensure the main power switch is on.
  • Check for blown fuses in the battery circuit (if applicable).
• Motor Not Running or Running Erratic:
  • Inspect motor phase wires and Hall sensor wires for correct and secure connections.
  • Check throttle connections and functionality.
  • Ensure brake cut-off switches are not engaged.
  • Verify motor compatibility with the controller's voltage and power rating.
• Controller Overheating:
  • Ensure the controller is mounted in a well-ventilated area.
  • Check for excessive load on the motor or vehicle.
  • Verify that the motor is not drawing excessive current.
• Unusual Noises:
  • While the sine controller is designed for silent operation, any unusual noises may indicate a loose connection or a motor issue. Inspect motor and controller connections.
