Changing the proximity switch / micro-switch
Proceed as follows:
Remove the cover.
Before disconnecting from the circuit board, mark the
electrical connections so that it will be possible to reconnect
them without error.
Disconnect all electrical connections to the proximity switch /
micro-switch from the printed circuit board (plug connections).
Loosen the four screws (Torx 10) with which the cover plate is
secured.
Remove the cover plate.
Note the positions of the proximity switch and the trigger of
the micro-switch.
Lift out the proximity switch / micro-switch with the adjusting
screw and the connecting cable.
Unscrew the old adjusting screws for re-use.
Screw the adjusting screws into the threaded holes on the
new proximity switch / micro-switch.
Only when there is a proximity switch:
Remove the O ring from the old proximity switch and insert it
into the clearance of the new proximity switch. (This O ring is
used to muffle vibration and prevents the proximity switch
from sliding out.)
Mount the new proximity switch with the adjusting screw in
the guide column.
ATTENTION!
Ensure the correct seating of the proximity switch / micro-switch in the guides
and depressions on the body.
Re-fit the cover plate.
ATTENTION!
Ensure the correct seating of the printed circuit
board and the screw heads in the projections
and cut-outs of the cover plate.
Firmly screw down the cover plate
(Torx 10; tightening torque 0,7 Nm).
Reconnect the electrical connections to the proximity switch /
micro-switch according to the note made earlier.
Adjust the position of the proximity switch / micro-switch:
- Using a screwdriver, turn the adjusting screw (spindle)
until the optimal position of the proximity switch has been
set up.
- The LED mounted on the proximity switch is an adjustment
aid: it lights up when reaching the corresponding threshold
value.
Refit the cover.
