Limit Switch (Item 17; Figs. 1 and 21)
In order to limit run-out times after overload has taken place, a
limit switch must be mounted onto the overload clutch.
The contactless limit switch is to be mounted onto the switching
edge of the clutch (Fig. 21) so that no signal changes are caused
during normal operation on the limit switch by the usual clutch
run-out errors.
In case of overload, the thrust washer (3) carries out a stroke
(see Table 1, page 7) in the direction of the adjusting nut (7)
(Fig. 1), which is used to change the signal on the limit switch.
The signal change should take place at the latest after an axial
thrust washer (3) stroke of 0,5 mm. At the same time, please
maintain a radial minimum distance of 0,5 mm in order to prevent
start-up of the contactless limit switch.
Limit Switch Installation
Adjust the switch distances for the contactless and mechanical
limit switch acc. Fig. 21. The distance of the thrust washer (3) to
the switching point can be easily adjusted using a hexagon head
screw, wrench opening 7.
