AS-Interface Safety at work

■Overview

■Application

SIGUARD cable-operated switches are used for monitoring or for EMERGENCY-STOP facilities on particulary endangered sys- tem sections.

As the effective range of a cable-operated switch is limited by the length of the cord, large systems can also be protected.

Specifications

Switches with latching for implementation in EMERGENCY-STOP equipment correspond to the EN 418 standard.

■Function

The safety contacts of the AS-Interface cable-operated switch are positively driven.

The AS-Interface cable-operated switches are ready to operate after pretensioning of the pull-wire or the rope.

When the rope is pretensioned, it must be released before the cable-operated switch can be returned to the original state.

It is also possible to connect AS-Interface cable-operated switches via the standard AS-Interface with safety-oriented com- munication.

In this case, the safety functions no longer have to be conven-

6tionally wired up.
