The time is reset if the status at input En returns to 1
before the on-delay time has expired.
Stairway Lighting Switch
Description of function
The edge of an input pulse triggers a configurable time.
The output is reset when this time has expired. An off
warning can be output prior to the expiration of this time.
Connection
Description
Trg input ( )
You trigger the time (off delay) for
the stairway switch with a signal at
input Trg (Trigger).
Parameter
T: The output is reset (1 to 0
transition when the time T has
expired.
T
!
: Determines the triggering time
for the pre-warning.
T
!L
: Determines the length of the
pre-warning time.
Retentivity set (on) = the status is
retentive in memory.
Output Q
Q is reset after the time T has
expired. A warning signal can be
output before this time has expired.
Parameter
The off-delay time T, the pre-warning time T! and the pre-
warning period T!L can be provided by the actual value of
another already-programmed function:
Analog comparator (Ax – Ay) Analog threshold trigger
(Ax)
Analog amplifier (Ax) Analog multiplexer (AQ)
Analog ramp (AQ) Mathematic instruction
(AQ)
PI controller (AQ) Up/down counter (Cnt)
Analog filter (AQ) Average value (AQ)
Max/Min (AQ) On-delay (Ta)
Off-delay (Ta) On-/off-delay (Ta)
Retentive on-delay (Ta) Wiping relay(pulse output)
(Ta)
