The reduction gearing is available for a range between 1.38 and 1,450 turns per
stroke (turns/stroke). The range is divided into two sections: III (1.38 – 135turns/
stroke, large gear wheel on small gear wheel) and II (12.4 – 450 turns/stroke; small
gear wheel on large gear wheel). Changing between these ranges requires exchan-
ging the gear wheels on the base of the limit switch base. By moving the sliding gear
wheel in one of the positions 4 – 11, the required travel range can be selected.

The values of the sliding gear wheel positions 1 – 3 are available on request.
Preferably use the marked setting ranges.
Default setting unless ordered otherwise!
a) For output speed of 5 – 50 rpm, the factory setting is section III.
b) For output speed of 80 – 160 rpm, the factory setting is section II.
