4. Instalação e fiação

Careful wiring is essential for the correct and safe operation of the controller. Refer to the wiring diagram and follow the steps below.

Figure 4: Comprehensive wiring diagram illustrating each connector and its corresponding function for the controller.

Etapas de fiação:

1. Motor Line Connection: Connect the motor lines, ensuring that colors match (e.g., blue to blue, green to green, yellow to yellow).
2. Battery Line Connection: Connect the battery lines. The red wire is for positive (+), and the black wire is for negative (-).
3. Throttle and Electric Lock Connection: Connect the controller's throttle line. If your throttle does not have an electric lock, connect the controller's electric lock wire directly to the battery's positive (+) terminal.
4. Hall Line Connection: Connect the Hall sensor lines. If your motor does not have Hall sensors, this connection is not required.
5. Self-Learning Line (Intelligent Recognition):
   • Connect the two self-learning lines (often labeled "intelligent recognition" or "self-study").
   • The wheel will either rotate forward or in reverse.
   • If the wheel rotates forward, separate the self-learning lines.
   • If the wheel rotates in reverse, separate the self-learning lines, then dock them again. The wheel should now rotate forward. Once it rotates forward, separate the self-learning lines. This completes the motor phase learning process.
6. Funções adicionais: Connect other functions as needed, referring to the list below and the wiring diagram (Figure 4).

Controller Function Connections:

• Jog 3-speed / 4-speed: (Generally not used)
• 3-speed: For speed selection.
• Acelerador: Connects to the speed control handle.
• Low Brake: For low-level braking signal.
• Cruzeiro: For cruise control function.
• Reverter: For reverse gear function.
• Instrument Line: Connects to display driving speed, power, and mileage.
• Self-Learning Line: Used for motor phase recognition (as described in step 5 above).
• High Brake: If your brake lever has two wires, connect the black wire to the high brake input. The red wire connects to the controller's 12V converter. The high brake may not always be used depending on your setup.
• Salão: For Hall sensor input.
• First-line General LCD Instrument Line: For general LCD display connection.
• Anti-theft Signal: For anti-theft alarm signal input.
• Anti-theft Power Supply: For anti-theft system power.
• Electric Door Lock: Connects to the throttle's electric lock. If the throttle lacks an electric lock, connect this to the battery's positive (+) terminal.
• Cabo de alimentação: Entrada de energia principal.
• Motor Line: Connects to the motor phases.

5. Instruções de operação

Once the controller is correctly installed and wired, follow these general operating guidelines:

• Ligar: Ensure all connections are secure before turning on the main power supply to your electric bicycle or scooter.
• Controle de aceleração: Use the speed control handle (throttle) to regulate motor speed.
• Modos de velocidade: If connected, utilize the 3-speed function to select desired power output levels.
• Frenagem: Apply brakes as usual. The controller will cut power to the motor when a brake signal is detected (low or high brake).
• Controle de cruzeiro: Activate the cruise function for maintaining a constant speed, if connected.
• Reverter: Engage the reverse gear function when needed, if connected.
• Informações do visor: If an instrument line is connected, monitor your speed, power, and mileage on the display.

6. Solução De Problemas

If you encounter issues with your yuandai Intelligent Brushless Controller, consider the following:

• Sem energia:
  • Check battery connections (red to +, black to -).
  • Verify the electric door lock connection.
  • Certifique-se de que a bateria esteja carregada.
• Motor Not Running or Stuttering:
  • Re-check motor phase line connections (color to color).
  • Perform the self-learning procedure again (Section 4, Step 5) to ensure correct motor phase recognition.
  • Verify Hall sensor connections if your motor uses them. If the motor does not have Hall sensors, ensure the Hall lines are disconnected.
• Motor Runs in Reverse:
  • Repeat the self-learning procedure (Section 4, Step 5) to correct motor direction.
• Superaquecimento do controlador:
  • Ensure the controller is mounted in a location with adequate airflow for cooling.
  • Verify that the motor is not drawing excessive current due to a fault or being undersized for the application.
• Volumetage Compatibilidade:
  • This controller is rated for 48V-84V. Operating consistently at the absolute upper limit (e.g., 84V) may reduce its lifespan or cause failure under certain conditions. Ensure your battery voltage is within the recommended operating range and does not exceed the maximum voltage under full charge.

If problems persist, consult a qualified technician or contact yuandai customer support.

7. Manutenção

The yuandai Intelligent Brushless Controller is designed for durability and requires minimal maintenance. Follow these guidelines to ensure longevity:

• Mantenha limpo: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can hinder heat dissipation.
• Inspecionar conexões: Regularly check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Evite a exposição à água: While the aluminum casing offers some protection, avoid direct exposure to heavy rain or submersion in water to prevent internal damage.
• Montagem adequada: Ensure the controller is securely mounted to prevent vibrations and physical damage during operation.
