4. Setup and Installation

Proper installation is critical for the controller's functionality and safety. It is highly recommended that installation be performed by a qualified professional.

Installation Steps:

1. Preparation: Ensure the vehicle's power is completely off and the battery is disconnected. Gather all necessary tools and components.
2. Mounting: Select a secure and well-ventilated location for the controller. Use the provided screws to firmly mount the controller, ensuring it is protected from physical damage and excessive moisture.
3. Wiring Connections: Refer to the wiring diagram (if provided with your specific kit) and the general guidelines below for connecting the controller.

Wiring Guidelines:

The controller comes with a wiring harness for various connections. Identify each wire bundle carefully before connecting.

• Battery Connection: Connect the main power wires from the controller to the battery, ensuring correct polarity (positive to positive, negative to negative).
• Motor Connection: Connect the phase wires from the controller to the motor. For brushless DC motors, also connect the Hall sensor wires.
• Ignition/Key Switch: Connect the ignition wire to the vehicle's key switch or power lock.
• Throttle: Connect the throttle input wires.
• Brake Levers: Connect the brake signal wires. The controller supports both positive (12V) and negative compatible brake modes.
• Other Signals: Connect any additional wires for features such as speed display, reverse, cruise control, etc., as per your vehicle's requirements.

Self-Learning Function:

After initial wiring, the brushless DC controller may require a self-learning process to optimally match with your motor. Consult the electronic manual (if provided) or your professional installer for specific instructions on initiating this function.

5. Operation

Once properly installed and wired, the controller manages the power flow to your electric motor based on your throttle input and other vehicle signals.

• Power On: Turn the vehicle's key switch to the 'ON' position. The controller will initialize.
• Throttle Control: Gently apply the throttle to accelerate. The controller's FOC (Field-Oriented Control) mode ensures smooth and efficient power delivery.
• Braking: Engaging the brake levers will signal the controller to cut power to the motor, contributing to safe deceleration.
• Monitoring: Pay attention to any vehicle display indicators for battery level, speed, and error codes.

6. Maintenance

Regular, simple maintenance can help ensure the longevity and reliable performance of your controller.

• Keep Clean: Periodically clean the exterior of the controller with a dry, soft cloth. Avoid using liquids or harsh chemicals.
• Check Connections: Regularly inspect all wiring connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent power or component failure.
• Environmental Protection: Ensure the controller remains protected from extreme temperatures, direct sunlight, and moisture.
• Physical Inspection: Check for any signs of physical damage to the controller casing or wires.

7. Troubleshooting

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

• Motor Not Responding:
  • Check if the battery is charged and properly connected.
  • Verify that the ignition switch is on.
  • Inspect all motor and throttle connections for looseness or damage.
  • Ensure brake levers are not engaged, as they cut motor power.
• Intermittent Power:
  • Check battery terminals and main power connections for corrosion or looseness.
  • Inspect wiring harness for any frayed or damaged wires.
• Overheating:
  • Ensure the controller has adequate ventilation and is not covered.
  • Reduce prolonged heavy loads if possible.
• Unusual Noises:
  • Could indicate a motor issue or incorrect motor phasing. Re-run the self-learning function if applicable, or consult a professional.

If troubleshooting steps do not resolve the issue, contact customer support or a certified technician.
