Delay - Reer MZERO Installation, Use And Maintenance Manual

DELAY

DELAY operator applies a delay to a signal by setting the
output to 1 (TRUE) after the set time, against a change in
the level of the input signal.
Parameters
Time: The delay can be set to between
10 ms and 1098,3 s
Scale: The user can choose two different scales for the
time T to be set.
•
10 ms...60 s, step 10 ms
•
60,1 s...1098,3 s, step 100 ms
Rising edge: If selected, the delay starts on the input signal's rising edge at the end of which the
output changes to 1 (TRUE) if the input is 1 (TRUE) where it remains for as long as the input stays
at 1 (TRUE).
If not selected the logic is inverted, the output is set to 1 (TRUE) on the input signal's rising edge,
the delay starts on the input signal's falling edge, at the end of the set time the output changes
to 0 (FALSE) if the input is 0 (FALSE) otherwise it remains 1 TRUE.
In
Out
Retriggerable: If selected the time is reset each time the input status changes.
