2.2 Special versions
For special versions, which are not listed in the ordering code, these specifications apply accordingly, provided that
they correspond to the standard version.
FSpecial information or information deviating from the standard on special versions can be found in the concluding chapter
"Appendix – Special versions".
2.3 Purpose
The non-contact, electronic safety switchgear is designed for application in safety circuits and is used for monitoring
the position and locking of movable safety guards.
F
The safety switchgears are classified according to ISO 14119 as type 4 interlocking devices. Designs with individual coding are classified as
highly coded.
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.
Series-wiring
Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction time
increases by the sum of the reaction time of the inputs per additional unit specified in the technical data. The quantity
of devices is only limited by the cable drops and the external cable fuse protection, according to the technical data. Up
to 31 device variants with serial diagnostics can be wired in series.
2The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level. If
multiple safety sensors are involved in the same safety function, the PFH values of the individual components must be added.
2The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant
standards.

3 Mounting
3.1 General mounting instructions
9-21

2Please observe the relevant requirements of the standards ISO 12100, ISO 14119 and ISO 14120.
For fitting the solenoid interlock, two mounting holes for M6 screws with washers (washers included in delivery) are
provided. The solenoid interlock must not be used as an end stop. Any mounting position. The mounting position
however must be chosen so that the ingress of dirt and soiling in the used opening is avoided. The unused actuator
opening must be sealed by means of the dust-proof flap (included in delivery).
Minimum distance between two solenoid interlocks
as well as other systems with same frequency (125 kHz): 100 mm
Mounting of the solenoid interlock and the actuator
Refer to the mounting instructions manual for the corresponding actuator.
2The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).
