remains set.
When Ta reaches the value defined at T (Ta=T), the output Q is reset to 0 state (pulse output).
If the signal at input Trg changes from 1 to 0 before this time has expired, the output is immediately reset
from 1 to 0.
5.5.6 Edge triggered wiping relay
Fashion: Classic:
Short description
An input pulse generates a preset number of output pulses with a defined pulse/pause ratio
(retriggerable), after a configured delay time has expired.
Parameter
The pulse width TH and the inter-pulse width TL can be provided by the actual value of another
already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller:AQ
Data latching relay: AQ
Up/Down counter: Cnt
Connection Description
Input Trg You trigger the times for the Edge-triggered wiping relay
with a signal at input Trg (Trigger).
Input R The output and the current time Ta are reset to 0 with a
signal at input R.
Parameter TL, TH: The inter-pulse period T
L
and the pulse period T
H
are
adjustable.
N determines the number of pulse/pause cycles T
L
/ T
H
:
Value range: 1...9.
Retentivity set (on) = the status is retentive in memory.
Output Q Output Q is set when the time T
L
has expired and is reset
when T
H
has expired.
