10. Motor Cable: Connects to the brushless motor.

8. Installation Guide

Follow these general steps for installing the controller. Specific wiring may vary based on your e-bike model. Always refer to your e-bike's specific wiring diagram if available.

1. Power Disconnection: Ensure the battery is completely disconnected before starting installation.
2. Mounting: Securely mount the controller in a suitable location on your e-bike, ensuring it is protected from water and physical damage. The compact design allows for flexible placement.
3. Motor Connection: Connect the motor cable (11) from the controller to your brushless motor. Ensure a secure connection.
4. Power Connection: Connect the power supply interface (10) to your 48V battery. Observe correct polarity.
5. Display Connection: Connect the display interface (9) to your KDS protocol display meter.
6. Throttle Connection: Connect the throttle interface (2) to your throttle unit.
7. Brake Connections: Connect the brake interfaces (3) to your brake levers. These typically cut power to the motor when activated. Connect the brake light interface (1) and stop lamp/rear lamp interface (4) as applicable.
8. Accessory Connections: Connect the horn switch interface (5), headlight & horn interface (6), and assistance interface (7) to their respective components.
9. Final Check: Double-check all connections for security and correct polarity. Ensure no wires are pinched or exposed.
10. Power On: Reconnect the battery and power on your e-bike system to test functionality.

9. Operation

Once correctly installed, the X098-AXD001 controller will manage the power delivery to your brushless motor based on inputs from the throttle, pedal assist sensor, and brake levers, as interpreted by the KDS protocol display. The display will provide information on speed, battery level, and other operational parameters.

• Throttle Control: Use the throttle to manually control the motor's speed.
• Pedal Assist: If an assistance sensor is connected, the motor will provide power based on your pedaling input and the selected assist level on your display.
• Braking: Activating the brake levers will cut power to the motor, ensuring safe stopping.

10. Maintenance

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

• Keep Clean: Periodically clean the exterior of the controller to prevent dust and dirt buildup, which can hinder heat dissipation. Use a dry, soft cloth.
• Inspect Connections: 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.
• Avoid Water Exposure: While the aluminum casing offers some protection, avoid submerging the controller in water or exposing it to heavy rain for extended periods.
• Temperature Management: Ensure the controller is mounted in a location with adequate airflow to facilitate heat dissipation, especially during prolonged use.

11. Troubleshooting

If you encounter issues with your motor controller, consider the following common troubleshooting steps:

• No Power/No Response:
  • Check battery charge level.
  • Verify all power connections are secure and correctly polarized.
  • Ensure the display is powered on and functioning.
• Error Messages on Display:
  • Refer to your display meter's manual for specific error code meanings.
  • Crucially, re-verify controller model (X098-AXD001) and KDS protocol compatibility. Incompatible components are a common cause of errors.
  • Check all sensor and signal wire connections (throttle, brake, PAS).
• Intermittent Operation:
  • Inspect all wiring for loose connections or damaged insulation.
  • Ensure the controller is not overheating.
• Motor Not Responding to Throttle/PAS:
  • Check throttle and PAS sensor connections.
  • Ensure brake levers are not engaged, as they cut motor power.

If issues persist after troubleshooting, contact customer support for further assistance.
