Delay times (0 ... 50 s)

This makes it possible to lter out unwanted level uctuations 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).
