Short description

Switch with two different functions:
● Pulse switch with off-delay
● Switch (permanent lighting)

Wiring

Description

Input Trg

A signal at input Trg (Trigger) sets output Q

(permanent light) or resets Q with an off-delay. When

active, output Q can be reset with a signal at input

Trg.

Input R

A signal at input R resets the current time T

and

resets the output.

Parameter

T represents the off-delay time. The output is reset (1

to 0 transition) when time T expires.
T

represents the time during which the output must

be set to enable the permanent light function.
T

represents the on-delay for the prewarning time.

represents the length of the prewarning time

period.
Retentivity:

/ = No retentivity

R = The status is retentive.

Output Q

A signal at Trg switches on output Q. Depending on

the length of the input at Trg, the output is switched

off again or switched on permanently, or it is reset

with a further signal at Trg.

Parameters T, T

and T

Note the defaults of the T parameters listed in topic Time response (Page 151).
The off-delay time T, the permanent light time T

, the on-delay prewarning time T

and the

prewarning time period T

can be provided by the actual value of another already-

programmed function. You can use the actual values of the following functions:
●  Analog comparator (Page 218) (actual value Ax – Ay)
●  Analog threshold trigger (Page 213) (actual value Ax)
●  Analog amplifier (Page 226) (actual value Ax)
●  Analog multiplexer (Page 248) (actual value AQ)
●  Analog ramp (Page 251) (actual value AQ)
●  Mathematic instruction (Page 265) (actual value AQ)
●  PI controller (Page 256) (actual value AQ)
●  Up/down counter (Page 201) (actual value Cnt)
