Tilt > 5⁰
Chair is more than 5⁰ out of level
Normal stop

Go to mode -3- and press the [E] button. Levelling must now move
to the 0 position.

If the levelling of the chair works correctly, this error can have
occurred because the lift went around a corner too quickly so that the
level motor was unable to keep the chair horizontal. It is also possible
that the level motor had insufficient force in this situation.
If the nulling of the chair does not work in mode -3-, there is a
hardware fault.

Check the connections on the sensor board and the safety board

Check the cables between the sensor board, the safety board and the
control board.

Check the connections of the level motor on the control board.

Replace the safety board if it behaves suspiciously.

Replace the control board if none of the above solutions has helped
or if the fault keeps coming back.

F06
Speed higher than programmed
Speed is more that 130% from the programmed speed
