Delay times (0 ... 50 s)
This makes it possible to filter out unwanted level fluctuations of
a short duration or a high frequency (damping).
The level must be present for at least a certain pre-set time
for the output to switch on. The output does not immediately
change its status when it reaches the switching event (SP), but
rather only after the pre-set delay time (DS).
If the switching event is no longer present after the delay time,
the switch output does not change.
The output only switches back when the level has fallen down
to the reset point (PR) and stays at or below the reset point (RP)
for at least the pre-set delay time (DR).
