If "Error 010" appears on the display, this typically indicates a communication incompatibility between the S900 display and your e-bike's controller. This display may not be universally compatible with all e-bike controllers, even if the voltage matches. Verify the communication protocol of your e-bike's controller with the S900's protocol (Protocol 2). Consult your e-bike's manufacturer or a qualified technician for compatibility information.
Display Not Powering On
- Check all wiring connections, especially the power cord (Red VCC) and ground wire (Black GND), as per the wiring diagram in the Setup section.
- Ensure your e-bike's battery is charged and providing power to the system.
