Setting the switch-on delay (On Delay)
This setting is used to delay the switching on of the output by a set amount of time if
the measured value exceeds the threshold.
This setting prevents the input and output from repeatedly switching on and off within a
short period of time and enables the use of a slower PLC.
The delay is increased by the configured time by switching the switching output to
ON
.

Shorter than the defined time period

The measured value is of equal size or greater than the threshold
Output switches to OFF
4
The measured value is below the threshold
Output switches to ON
Values are possible from 0 ms (default value) to 100 ms.
7.3.7.4
Setting the switch-off delay (Off Delay)
This setting is used to delay the switching off of the output by a set amount of time if
the measured value falls below the threshold.
This function suppresses short signals (bursts) which prevents inaccurate measure‐
ments.
