Wiring Instructions:

1. Power Connection: Connect the main power wires (typically red for positive, black for negative) from your battery to the controller's "Power" input. Ensure correct polarity.
2. Motor Phase Lines: Connect the three thick motor phase wires (usually yellow, green, blue) from the controller to the corresponding motor phase wires.
3. Hall Sensor Wires: Connect the smaller Hall sensor wires (typically five wires: red, black, yellow, green, blue) from the controller to the motor's Hall sensor connector.
4. Electric Door Lock: Connect the electric door lock wire (often red/orange) to your vehicle's ignition or power switch.
5. Speed Control Handle (Throttle): Connect the throttle wires (typically red, green, black) to the speed control handle.
6. Brake Levers: Connect the "Low Level Brake" and "High Level Brake" wires to your brake levers. These provide signals to cut motor power during braking.
7. Shift Three-speed Gear: If your vehicle has a three-speed gear function, connect the corresponding wires.
8. Anti-theft Alarm Signal/Power: Connect these wires if your system includes an anti-theft alarm.
9. Reverse Gear: Connect this wire if your vehicle supports a reverse function.
10. Learning Wire: These two wires are typically used for initial motor identification. Connect them briefly, allow the motor to spin, then disconnect. Refer to specific motor instructions for this process.
11. Multiple Data Meter: Connect to your vehicle's display unit for speed, battery level, and other data.

After all connections are made, double-check each wire against the diagram and ensure they are firmly seated. Incorrect wiring can damage the controller or other components.

Operating Instructions

Once the controller is correctly installed and all connections are secure, follow these steps to operate your electric vehicle:

1. Power On: Turn on the electric door lock or ignition switch. The display (if connected) should illuminate.
2. Throttle Control: Gently twist the speed control handle (throttle) to accelerate. The motor will respond proportionally to the throttle input.
3. Braking: Apply the brake levers to slow down or stop. The controller will cut power to the motor when the brakes are engaged.
4. Gear Shifting (if applicable): Use the three-speed gear switch to select your desired speed mode.
5. Reverse (if applicable): Engage the reverse switch to move backward.

Always operate your vehicle responsibly and in accordance with local regulations. Avoid sudden acceleration or braking to prolong the life of your motor and controller.

Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your Keenso Brushless Motor 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 wiring connections for looseness, corrosion, or damage. Tighten any loose connections.
• Avoid Overheating: Ensure the controller is mounted in a location with adequate airflow to prevent overheating, especially during prolonged use or high loads.
• Environmental Protection: Protect the controller from direct exposure to rain, excessive moisture, and extreme temperatures.
