4. Configuració i instal·lació

Careful wiring is crucial for the correct and safe operation of the motor controller. Refer to the detailed wiring diagram below and ensure each connection is made accurately.

Image 4.1: Comprehensive wiring diagram illustrating the connections for the motor controller. Key connections include:

• Motor Line: Connects to the motor phases (typically three thick wires).
• Positive Electrode / Negative Electrode: Main power input from the battery.
• Bloqueig: Ignition switch connection.
• Alarm Power Supply / Alarm Wire: For security system integration.
• Study Wire: Used for initial motor learning/pairing.
• Sala: Hall sensor connections from the motor.
• Creuer: For cruise control functionality.
• High Brake / Low Brake: Connections for brake levers (high or low electrical level).
• Revers: For reverse gear functionality.
• Instruments / LCD Display: Connections for dashboard display or LCD panel.
• Acceleració: Connects to the throttle grip.
• Three Speed: For multi-speed selection.

Passos d'instal·lació:

1. Muntar el controlador: Securely mount the controller in a location that is protected from direct impact, water, and excessive heat, allowing for adequate airflow around its aluminum casing.
2. Connecteu els cables del motor: Connect the three thick motor phase wires from the controller to the corresponding motor phase wires.
3. Connect Hall Sensor Wires: Connect the smaller Hall sensor wires from the controller to the motor's Hall sensor wires.
4. Connect Battery Power: Connect the main positive and negative power wires from the controller to your 48-72V battery, ensuring correct polarity.
5. Connect Ignition Lock: Connect the ignition lock wire. The controller will only power on when this circuit is closed.
6. Connect Throttle: Attach the throttle wire to the throttle grip.
7. Connect Brake Levers: Connect the High Brake and/or Low Brake wires to your brake levers.
8. Connecteu els accessoris: Connect any additional accessories such as the LCD display, instruments, alarm system, cruise control, or three-speed switch as per the diagram.
9. Perform Study Wire Pairing (if applicable): Some controllers require a 'study wire' connection to automatically identify motor parameters. Follow specific instructions for your motor if this feature is present.
10. Verifica les connexions: Double-check all connections for tightness and correct placement before applying power.

5. Instruccions de funcionament

Once properly installed, the WFLNHB motor controller provides sensitive and efficient control over your brushless DC motor. This controller supports a 2-mode operation, allowing for flexible power delivery.

• Encès: Turn the ignition key (if connected) or activate the main power switch. The controller will perform a self-check.
• Control de l'accelerador: Gently twist the throttle grip to accelerate. The controller's sensitive response ensures smooth acceleration and deceleration.
• Frenatge: Engaging the brake levers will cut power to the motor, providing a safe stop. The controller supports both high and low electrical level brake signals.
• 2-Mode Operation: The controller is designed with a 2-mode function, which typically refers to dual-mode control (e.g., Hall sensor mode and sensorless mode). This allows for continued operation even if Hall sensors fail, or provides optimized performance under different conditions. Consult your motor's specifications for optimal mode utilization.
• Speed Selection (if connected): If a three-speed switch is connected, use it to select your desired speed mode (e.g., low, medium, high).

6. Manteniment

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

• Inspecció periòdica: Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure no wires are pinched or exposed.
• Neteja: Keep the controller free from dust, dirt, and debris. Use a dry, soft cloth to wipe down the exterior. Do not use liquid cleaners directly on the controller.
• Dissipació de calor: Ensure the controller's mounting location allows for adequate airflow to its aluminum casing. Do not obstruct the heat dissipation fins.
• Protecció del medi ambient: Protect the controller from direct exposure to rain, snow, or extreme humidity.
• Salut de la bateria: Maintain your battery according to its manufacturer's instructions. A healthy battery contributes to stable controller operation.

7. Solució De Problemes

If you encounter issues with your motor controller, refer to the following common problems and solutions:

• El motor no respon:
  • Comproveu el nivell de càrrega de la bateria.
  • Verify all power connections (positive, negative, ignition lock).
  • Inspect throttle wiring for damage or loose connections.
  • Ensure motor phase and Hall sensor wires are correctly connected.
• Intermittent Power/Operation:
  • Check for loose or corroded connections, especially main power and motor wires.
  • Inspect for any short circuits or damaged insulation on wires.
  • Ensure the controller is not overheating (check mounting and airflow).
• Motor Runs Rough or Makes Unusual Noise:
  • Verify Hall sensor connections are correct and undamaged.
  • Check motor phase wire connections.
  • If the controller has a 'study wire' function, re-perform the motor learning process.
• Brakes Not Functioning Correctly:
  • Check brake lever switch wiring to the controller.
  • Ensure the brake signal type (high/low electrical level) matches the controller's input.
