Hysteresis function
When using the hysteresis function, a switch window is taught in that is defined by two switch-
ing points. The switching outputs have the following behavior as outputs:
If an object is moved away from the sensor, the switching output is switched on for as long as
the object is located between the beginning of the detection range and switching point 2. If
the object passes switching point 2, the switching output is switched off. If an object is moved
towards the sensor, the switching output is switched off for as long as the object is located
between the beginning of the detection range and switching point 1. If the object passes
switching point 1, the switching output is switched on.

Behavior of the analog output
Output 2 is factory set as an analog output and can be used either as a 4…20 mA/0…20 mA
current output, a 0…10 V/0…5 V/1…6 V voltage output or as a switching output. The analog
output behaves as follows:

The analog output transmits 0 V or 4 mA in the event of echo loss.
