ChongXiao Universal BLDC Brushless Controller User Manual

1. Introduzione

This manual provides detailed instructions for the installation, operation, and maintenance of the ChongXiao Universal BLDC Brushless Controller. This controller is designed for electric bikes and e-scooters, supporting various voltage ranges (24V, 36V, 48V, 60V) and power outputs (250W, 350W) with current ratings from 10A to 20A. It features a brushless design for smooth, stable, and long-lasting performance.

2. Configurazione e installazione

Proper installation is crucial for the safe and efficient operation of your electric bike or e-scooter. Please follow these steps carefully.

2.1 Funzioni del controller

The controller supports the following functions:

• Low-level brake
• Controllo della velocità di crociera
• Brake light power output
• PAS (sistema di pedalata assistita)
• Retromarcia
• High-level brake
• Speed controller handle (throttle) input
• Phase meter connection
• Three-speed gear selection
• Hall meter connection
• Hall sensor (5 wires) connection
• Intelligent recognition (self-learning lines)
• Head/tail light power output
• Electric door lock input
• Phase line connection
• Ingresso alimentazione a batteria

2.2 Fasi di connessione

Refer to the wiring diagrams below for visual guidance. Ensure all connections are secure and correct before applying power.

Image 2.2: Detailed wiring diagram with numbered labels corresponding to the controller's functions. This diagram is essential for correct installation.

1. Connect the Motor Line: Connect the motor phase lines (usually three thick wires) from the controller to the motor, ensuring color-to-color matching.
2. Connect the Battery Line: Connect the battery power lines. The red wire is for battery positive (+), and the black wire is for battery negative (-).
3. Connect the Throttle Line: Connect the speed controller handle (throttle) line. If your throttle does not have an electric lock, the controller's two electric lock wires can be shorted together.
4. Connect the Hall Line: Connect the Hall sensor lines from the controller to the motor's Hall sensors, ensuring color-to-color matching.
5. Intelligent Recognition (Self-Learning):
   • Spegnere la corrente.
   • Connect the two intelligent recognition lines together.
   • Turn on the power. The wheel will either rotate forward or reverse.
   • If the wheel rotates forward, separate the intelligent recognition lines.
   • If the wheel rotates in reverse, separate the intelligent recognition lines, then connect them together again. The wheel should now rotate forward. Once it rotates forward, separate the two intelligent recognition lines.

   This process adjusts the controller's phase ratio and adapts it to the battery voltage. Nota: When using throttle control for speed, the two intelligent recognition lines must be separated.

6. Connect Other Functions: Connect other functions such as low-level brake, cruise, brake light power, PAS, reverse gear, high-level brake, phase meter, three-speed gear, hall meter, head/tail light, and electric door lock as needed, referring to Image 2.2 for wire identification.

3. Istruzioni per l'uso

Once the controller is correctly installed and configured, you can operate your electric bike or e-scooter using the connected accessories.

3.1 Funzionamento di base

• Accensione/spegnimento: Use the electric door lock (if connected) or the main power switch of your vehicle to turn the system on or off.
• Controllo della velocità: Use the speed controller handle (throttle) to adjust the motor's speed.
• Frenata: Apply the brakes. The controller supports both low-level and high-level brake inputs, which will cut off motor power when activated.

3.2 Funzioni avanzate

• Controllo della velocità di crociera: If connected, activate the cruise function to maintain a constant speed without continuously holding the throttle.
• Cambio a tre velocità: Select between different speed modes (e.g., low, medium, high) using the connected three-speed gear switch.
• Sistema di pedalata assistita (PAS): If your vehicle has a PAS sensor and it's connected, the motor will provide assistance when you pedal.
• Retromarcia: Activate the reverse function (if connected) for backward movement, typically at a reduced speed.
• Luci: If head/tail lights are connected to the controller's output, they can be controlled via the vehicle's light switch.

4. Manutenzione

To ensure the longevity and optimal performance of your ChongXiao BLDC Brushless Controller, follow these general maintenance guidelines:

• Mantenere asciutto: Protect the controller from water and excessive moisture. While the aluminum casing offre una certa protezione, ma non è completamente impermeabile.
• Pulisci regolarmente: Periodically clean the exterior of the controller with a dry, soft cloth to remove dust and dirt. Do not use harsh chemicals or abrasive materials.
• Ispezionare le connessioni: Regularly check all wire connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or component failure.
• Evitare il surriscaldamento: Ensure the controller is mounted in a location with adequate airflow to prevent overheating, especially during prolonged use or high power demands.
• Maneggiare con cura: Avoid dropping or subjecting the controller to strong impacts, which can damage internal components.

5. Risoluzione Dei Problemi

This section provides solutions to common issues you might encounter with your controller.

5.1 Problemi comuni e soluzioni

• Motore non in funzione:
  • Check battery connection: Ensure the battery is charged and correctly connected to the controller.
  • Check motor phase lines: Verify that the three thick motor wires are securely connected and matched by color.
  • Check Hall sensor lines: Ensure the Hall sensor wires (5 wires) are correctly connected.
  • Check throttle connection: Confirm the throttle is properly connected and functioning.
  • Perform intelligent recognition: If not done or if connections were changed, repeat the intelligent recognition process (Section 2.2, Step 5).
• Motor Runs in Reverse:
  • This indicates an incorrect phase match. Repeat the intelligent recognition process (Section 2.2, Step 5) to correct the motor's rotation direction.
• Intermittent Power/Operation:
  • Inspect all wire connections for looseness or corrosion. Secure any loose connections.
  • Check for damaged wires or connectors. Replace if necessary.
• No Brake Function:
  • Verify the brake lever wires are correctly connected to the controller's low-level or high-level brake inputs.
  • Ensure the brake levers themselves are functioning correctly.
