If the torque set is exceeded, the coupling disengages with the shifting ring being moved back axially by
dimension H (see table 10).
The sensor or limit switch has to be mounted such that signal recording is ensured in this shifting range.
The sensor or limit switch has to be aligned versus SYNTEX

-NC such that signal recording of the
disengagement process is ensured.

Function
The axial stroke of the shifting ring generated with overload may activate a mechanical limit switch or an inductive
sensor. As a result a control signal is generated which can be evaluated for disengaging the drive.
Assembly
The sensor needs to be mounted in a solid device to ensure a smooth operation. The sensor should be protected
from dirt and potential mechanical faults.
!
We recommend using a limit switch!
Please absolutely observe the operation of the limit switch before the machine is supplied.
Please also observe the operating instructions for the sensor or limit switch, respectively.
The axial stroke of the shifting ring must not be blocked by any other components.
As soon as the limit switch or sensor is activated (overload: release of overload coupling)
the drive should immediately be stopped.
With higher speeds respective braking devices may be necessary.
