Description
A signal at input Trg (Trigger) triggers the off-delay
time for the stairwell light switch.
T represents the off-delay time of the output (output
signal transition 1 to 0).
T determines the triggering time for the pre-warning.
T determines the length of the pre-warning signal.
L
Retentivity:
/ No retentivity
R The status is retentive.
