The filter depth indicates the necessary number of consistent beam states before the evaluation
of the measurement values.
All measurement values are accumulated and retained over the duration of the integration time.

To prevent mutual interference, multiple light curtains can be operated with a time offset with
respect to one another (cascade). Here, the master generates the cyclical trigger signal; the
slaves start their measurement after delay times, which are to be set to different values.

In most applications, it is recommended that the teach values be stored in non-volatile memory.
Depending on the function reserve selected for the teach event, the sensitivity is higher or lower
(high function reserve = low sensitivity; low function reserve = high sensitivity).
