2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
AZ 415-33ZPK-
➀
No. Option Description
➀
1637 Gold-plated contacts
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 and S3 are 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 and the NO contacts are closed.
The user must evaluate and design the safety chain in
accordance with the relevant standards and on the required
safety level.

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 EN ISO 12100,
EN 953 and EN 1088.
