Only if the information described in this operating instructions
manual are realised correctly, the safety function and
therefore the compliance with the Machinery Directive is
maintained
2.2 Special versions
For special versions, which are not listed in the order code below 21,
these specifications apply accordingly, provided that they correspond to
the standard version
2.3 Purpose
Safety switches with separate actuators are suitable for movable safety
guards, which need to be closed to ensure the necessary operational
security The safety switches are used for applications, in which the
hazardous situation is terminated without delay when the safety guard
is opened When the safety guard is opened, the NC contacts are
positively opened and the NO contacts are closed
Operating principle
By closing the safety guard, switch insert S1 is released and switch insert
S2 actuated (differentiated operating principle) When the actuator is fully
inserted, the safety guard is not subject to any ejection force
The safety switchgears are classified according to
ISO 14119 as type 2 interlocking devices
The user must evaluate and design the safety chain in
accordance with the relevant standards and on the required
safety level
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards
