With the input signal Trg = 1, output Q is set to 1. The
signal also triggers the time Ta, while the output 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.
Edge Triggered Wiping Relay
Description of function
An input pulse generates a pre-set number of output
pulses with a defined pulse/pause ratio (retriggerable)
after a configured delay time has expired.
You trigger the times for the Edge-
triggered wiping relay with a signal
at input Trg (Trigger).
The output and the current time Ta
are reset to 0 with a signal at input
R.
T
L
, T
H
: The inter-pulse period TL
and the pulse period TH are
adjustable.
N determines the number of
pulse/pause cycles TL / TH:
Value range: 1...9.
Retentivity set (on) = the status is
retentive in memory
Output Q is set when the time T
L
has expired and is reset when T
H
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 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)
