Unlike the DELAY operator, the DELAY LINE operator does not filter any interruptions in the
IN input which are shorter than the set time.

This operator is recommended when using delayed OSSD (the OSSD must be programmed
with RESTART MANUAL).
LONG DELAY LINE
This operator applies a delay to a signal by
setting the "Out" output to 0 (FALSE) after the
set time when a falling edge is detected on the
"In" signal.
If In returns to 1(TRUE) before the end of the set
time the "Out" output still generates a negative
impulse lasting approximately twice the system
response time and delayed by the set time.
Parameters
Time: The delay can be set from 0.5 s to 54915 s.
Scale: The user can choose two different scales for the time T to be set.
•
0,5 s...3000 s, step 0,5 s
•
3005 s...54915 s, step 5 s

Unlike the DELAY operator, the LONG DELAY LINE operator does not filter out any
interruptions to the IN input that are shorter than the set time.

This operator is useful when using delayed OSSDs (the OSSD must be programmed with
