5. Setup and Installation

Installation of the ebike controller requires careful attention to wiring and component compatibility. It is highly recommended that installation be performed by an experienced ebike technician.

General Installation Steps:

1. Disconnect Power: Ensure the ebike battery is completely disconnected before starting any work.
2. Mount the Controller: Securely mount the controller in a protected location on your ebike, away from direct moisture and excessive heat. Ensure adequate airflow for cooling.
3. Connect Motor Wires: Connect the three phase wires (typically green, blue, yellow) from the controller to the corresponding motor phase wires.
4. Connect Hall Sensor Wires: Connect the Hall sensor wires (typically a small connector with five wires) from the controller to the motor's Hall sensor port.
5. Connect Battery Power: Connect the main power wires (red for positive, black for negative) from the controller to the ebike battery. Double-check polarity.
6. Connect Display/Throttle/Brakes: Connect the display unit (if applicable), throttle, brake levers (for cut-off switches), and any other accessories according to their respective wiring diagrams.
7. Initial Test: Once all connections are made and secured, reconnect the battery and perform a low-power test to ensure all components are functioning correctly before full operation.

Refer to your ebike's specific wiring diagram and the controller's detailed wiring instructions (if provided separately) for precise connections. Incorrect wiring can damage the controller, motor, or battery.

6. Operating Instructions

Once installed and powered on, the controller manages the ebike's motor functions. If equipped with an LCD display (sold separately or as an option), you can monitor and adjust settings.

Riding Modes:

The controller features three customizable riding modes:

• Eco Mode: Optimized for energy efficiency and extended range.
• Normal Mode: Balanced performance for everyday riding.
• Sport Mode: Provides maximum power and acceleration.

Mode selection and real-time information such as speed and battery level are typically managed through the connected LCD display. Consult your display's manual for specific instructions on navigating menus and changing settings.

7. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your controller.

• Keep Clean: Periodically clean the exterior of the controller to prevent dust and dirt buildup, which can affect heat dissipation.
• Inspect Connections: Regularly check all wiring connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent power or component damage.
• Avoid Moisture: While the controller has an IP65 waterproof grade, avoid prolonged exposure to heavy rain or submersion in water.
• Temperature Management: Ensure the controller is not operating in excessively hot environments, which can lead to overheating.

8. Troubleshooting

If you encounter issues with your ebike controller, consider the following basic troubleshooting steps:

• No Power: Check battery connections, battery charge level, and main power switch.
• Motor Not Responding: Verify all motor phase wires and Hall sensor wires are securely connected. Check throttle connection.
• Intermittent Operation: Inspect all wiring for loose connections or damaged insulation.
• Error Codes on Display: If an LCD display is connected and shows an error code, consult the display's manual for the meaning of the code and recommended solutions.
• Overheating: Ensure the controller has adequate ventilation and is not overloaded. Reduce power demand if necessary.

For persistent issues or complex problems, it is advisable to seek assistance from a professional ebike repair service.
