•
STATUS_ERROR
If there is an edge change 0 → 1 the outp ut is set to
1.
When there is an edge change 1
→ 0 the Off delay
is started.
After the Off delay has elapsed, the output is set to
0.
With the setting "True" the output is always active.

Function parameters
Off delay (ms)
100 .. 999999999 Delay in milliseconds
Prewarning (ms) 0 .. 999999999 Time of the Prewarning in milliseconds
The sum of Prewarning and Interruption must be
lower than the Off delay.
Interruption (ms) 0 .. 999999999 Duration of the interruption in milliseconds
The "Interruption" may not exceed the "Prewarn-
ing".
An interruption of 0 is only allowed when:
•
the "Warning" output is connected
or
•
Pre-warning = 0 and the "Warning" output is not
connected.
