Remedy
1. Do not press pedal whilst motor is in operation.
2. Make sure the WBE 4420 is not subjected to any
impact during measurement.
3. Check mains voltage (probably too low).
1. Switch off the WBE 4420 .
2. Lower the wheel guard, switch the WBE 4420 on
again without moving the wheel.
3. If the error message persists, contact customer
service.
1. Check that the light barrier PCB is protected
against light and provide a cover if necessary.
2. Check and if necessary replace the light barrier
PCB.
3. Check and if necessary replace the display PCB.
1. Bring the calliper gauge back to stand-by position.
2. Repeat calibration of the electronic calliper gauge .
Calibrate them before reactivating them.
Use a different board.
