6.16. THE LCD DISPLAYS THE MESSAGE “SEAT PROBLEM =
ENCODER”
This error message appears during the initial machine reset, when the CPU board does not receive
the encoder signal from the Bio servo board once it has detected a change in the alarm signal, after
enabling movement of the seat motor in one direction. This means that there is movement, but no
encoder signal.
