2.4 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 safety outputs
when the safety guard is opened and maintaining the safe switched off
condition of the safety outputs for as long as the safety guard is open.
The safety switchgears are classified according to
ISO 14119 as type 4 switching devices. Designs with
individual coding are classified as highly coded.
Safety sensors and actuators with latching (ordering suffix 'R') must
always be used in pairs. The latching force (approx. 18 N) exercised by
the permanent magnet keeps hatches and small guards closed, also in
a de-energised condition.
The system can be used as a door end stop up to 5 kg at 0.25 m/s.
The diagnostic output of the safety sensor alternatively can be used
as a conventional output or as a “serial output“ with input and output
channel.
Series-wiring (only 8-pin version)
Series-wiring can be set up. Response and risk times remain
unchanged by series-wiring. The number of components is only limited
by the external cable protection according to the technical data and
the line loss. Series-wiring of up to 31 RSS 36 … SD components with
serial diagnostics is possible.
In devices with the serial diagnostics function (ordering suffix -SD), the
serial diagnostics connections are wired in series and connected to a
SD Gateway for evaluation purposes.
Wiring examples for series-wiring, refer to appendix.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level. If multiple safety switchgears are involved in
the same safety function, the PFH values of the individual
components must be added.
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
