8. Board Terminal Cable Sequence Diagram
The wiring diagram illustrates the connection between the CDC11 display, a central connector (JL-F39-Z408JM, female front view), and the Button2 unit. The connector has pins for Red (5V), Black (GND), Green (ON/OFF), and Yellow (Button). The connection to Button2 is made via a USB 5V 0.5A cable, approximately 300±5mm in length with an outer diameter of 4.0mm.
9. Q&A
Q: Why is the display not able to start up?
A: Check the connector between the display and the controller.
Q: How to deal with an error code?
A: Ask the customer care at your local dealer.
10. Error Codes
| Error Code | Definition |
|---|---|
| 2 | Over current protection (controller) Check whether the connectors of the 3-phase power cable and the hall signal connectors are badly connected. If the problem persists after re-connecting, there might be an issue with the controller or motor. |
| 3 | Controller cannot properly drive the motor Check whether the connectors of the 3-phase power cable, hall signal, and power supply are badly connected. Verify if there's insufficient power to drive the system (e.g., during climbing or if the wheel is stuck). If the problem persists after re-connecting, there might be an issue with the controller or motor. |
| 4 | Undervoltage protection Battery voltage is too low. |
| 5 | Brake problem After turning on, check if the brake sensor is working properly. If the brake signal is less than 0.75V for a prolonged period, the brake may be faulty. |
| 6 | Hall signal problem Check if the connector of the motor's hall signal cable is well connected. If the problem persists after re-connecting, the hall motor sensor may be broken. |
| 7 | Throttle problem After turning on, check whether: A) the throttle is out of control, B) the throttle signal is less than 0.75V, or C) the customer turned the throttle before the system was active. The error can be resolved after the throttle is reset. |
| 8 | Broken controller |
| A/10 | Display / controller communication problem Yellow cable is disconnected. |
| D/13 | Controller program is wrong / 5V is wrong Check whether the brake signal is short with 5V. |
WARNING: Any manumission of the ebike electronic system will result in warranty decay.
