Wiring example

Note (Wiring diagram)

The wiring diagram is shown with guard doors closed and in de-energised condition.

Applications: #Picture#Bilddata/Sonstige/_quitz01.eps#/Picture# safety relay module for double reset

Start configuration: 2 time-dependent reset/on switches 1st and 2nd monitoring time between the 1st and 2nd reset button from 3 … 30 seconds adjustable through DIP switches

The monitoring time is set through DIP switches located below the cover of the enclosure front. (Factory setting: 3 seconds)

Actuator configuration: 1-channel control (output impulse approx. 200 ms) of the reset input of a downstream safety relay module

Edge detection: After the device is reset, the trailing edge is evaluated, so that errors, e.g. welded contacts or manipulations cannot lead to dangerous situations.
