these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Purpose
This non-contact, electronic safety sensor is designed for application in
safety circuits and is used for monitoring the position of movable safety
guards. In this application, the safety sensor monitors the position of
hinged, sliding or removable safety guards by means of the coded
electronic actuator.
The safety function consists of safely switching off the code
transmission when the safety guard is opened and maintaining the safe
switched off condition for as long as the safety guard is open.
An AS-Interface Safety at Work component functions on the basis of
an individual code generator (8 x 4 bit). This safety code is cyclically
transmitted over the AS-i network and monitored by a safety monitor.
The safety switchgears are classified according to
EN ISO 14119 as type 4 locking devices. Designs with
individual coding are classified as highly coded.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
