The off-delay time T is triggered when the status at input
Trg changes to 0 before the time T
L
has expired.
Output Q is reset when the Ta = T.
Before the off-delay time (T - T
!
) has expired, you can
output an off pre-warning that resets Q for the duration
of the off-pre-warning time T
!L
.
A further signal at input Trg always resets T and output Q.
Caution
The time base for the T, T
!
and T
!L
must be identical.
If retentivity is not set, output Q and the expired time are
reset after a power failure.
