7.1.4 Switching point and switching function

The switching point (SP1, SP2) defines the limit value of the device related to the medium present (cov-
ering) to which the output (OU1, OU2) is to modify its switching status. The setting is an indication for
the switching sensitivity of the device tip and can be adapted to the medium.
The release point (rP1, rP2) defines the limit value of the device related to the medium not present (un-
covering) to which the output (OU1, OU2) is to modify its switching status. The release point must be
lower than or equal to the switching point. When entering values for the release point greater than the
switching point, a diagnostic message is generated. The difference between the switching point and the
release point is defined as hysteresis (for example SP1 – rP1).
As long as the medium is between the two set points, the output is maintained to be constant, stable,
and without any change of state.
