2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
AZ 415-02/02YPK-2537-1
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 2.1,
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.
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.
When the safety guard is opened, the NC contacts are positively
opened.
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.

detection under certain circumstances.
3. Mounting
3.1 General mounting instructions
The mounting holes are accessible after removal of the cover.
The enclosure 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.
Mounting of the actuators:
See mounting instructions actuators.
Please observe the remarks of the standards ISO 12100,
EN 953 and ISO 14119.
The safety component and the actuator must be
permanently fitted to the safety guards and protected
against displacement by suitable measures (tamperproof
screws, gluing, drilling, pinning).
