L
for
the off delay.
Parameter Par T

is the time after which
the output is switched on

from 0 to 1).
T
L
is the time after which the
output is switched off (out-
put signal is switched from 1
to 0).
Output Q Q switches on after the
parameterized time T
H
has
elapsed if Trg is still set, and
switches off after the time T
L
has elapsed if Trg has not
been set again in the in-
terim.
