4.1 Instruccions de cablejat

  1. Connexió d'alimentació: Connect the main power cables (typically thicker red for positive and black for negative) from your 48V battery to the corresponding ports on the controller. Ensure polarity is correct.
  2. Connexió del motor: Connect the three phase wires (usually green, blue, yellow) from the motor to the controller's motor phase ports. Connect the Hall sensor wires (smaller wires, typically 5 or 6, with matching colors) from the motor to the controller's Hall sensor port.
  3. Connexió de l'accelerador: Connect the throttle cable (typically red, green, black) to the controller's throttle input port.
  4. Brake Lever Connection: Connect the brake lever cables to the controller's brake input ports. These typically cut power to the motor when activated.
  5. Display/Panel Connection (if applicable): If your e-bike has a display or control panel, connect its cable to the designated port on the controller.
  6. Altres connexions: Connect any other accessories such as pedal assist sensor (PAS), headlight, or taillight according to their respective color codes and controller ports.

After making all connections, double-check for security and correct polarity before applying power. Improper wiring can damage the controller or other components.

5. Funcionament

Once properly installed, the JH4AZ7050DZQR controller provides sensitive and reliable control over your e-bike's motor. When power is applied and the system is engaged (e.g., via throttle or pedal assist), the controller will regulate the motor's speed based on your input.

  • Control de velocitat: The controller translates throttle input into motor speed, allowing for smooth acceleration and deceleration.
  • Frenatge: When the brake levers are engaged, the controller will cut power to the motor, ensuring safe stopping.
  • Direction Changes: The controller facilitates sensitive control for changes in direction, contributing to a stable ride.

6. Manteniment

To ensure the longevity and optimal performance of your NULKOMMA controller, consider the following maintenance guidelines:

  • Dissipació de calor: The controller's aluminum alloy shell is designed with grooves for effective heat dissipation. Ensure the controller is mounted in a location that allows for adequate airflow and is not obstructed. Avoid covering the controller with materials that could trap heat.
  • Neteja: Periodically clean the exterior of the controller with a dry, soft cloth to remove dust and debris. Do not use liquid cleaners or immerse the controller in water.
  • Comprovacions de connexió: Regularly inspect all wiring connections for tightness and signs of wear or corrosion. Secure any loose connections.
  • Protecció d'alta temperatura: The controller features an automatic high-temperature protection mechanism. If the controller becomes excessively hot, it will temporarily cut off power to prevent damage. Allow the controller to cool down before resuming operation.
