Product description
2.1 Ordering code
AZ 15 ZV(1)K-(2)-(3)
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.
2.3 Purpose
The safety switches with separate actuator are suitable for sliding, hinged
and removable safety guards, which need to be closed in order to ensure the
necessary operational safety.
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.
The safety switchgears are classified according to EN ISO 14119 as type 2
interlocking devices.
The user must evaluate and design the safety chain in accordance with the
relevant standards and 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.
2.4 Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal
hazards or damages to machinery or plant components cannot be excluded. There
are no residual risks, provided that the safety instructions as well as the
instructions regarding mounting, commissioning, operation and maintenance are
observed.
2.5 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with the operating instructions
manual. The manufacturer shall accept no liability for damages resulting from
the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary repairs,
conversions and modifications to the device are strictly forbidden, the
manufacturer shall accept no liability for damages resulting from such
invasive work, arbitrary repairs, conversions and/or modifications to the
device.
2.6 Technical Data
Note about the safety classification
Basically suitable up to Cat. 1 / PL c.
With 2-channel usage with fault exclusion mechanism (if a fault exclusion to
the 1-channel mechanics is authorised) and suitable logic applicable up to
Cat. 3 / PL d
(Determined values can vary depending on the application-specific parameters
hop, dop and tcycle as well as the load.)
If multiple safety components are wired in series, the Performance Level to EN
ISO 13849-1 will be reduced due to the restricted error detection under
certain circumstances.
Mounting
3.1 General mounting instructions
Please observe the relevant requirements of the standards ISO 12100, ISO 14119
and ISO 14120.
The mounting dimensions are indicated on the rear of the component. 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. The unused
openings must be sealed by means of slot sealing plugs (AZ 15/16 – 1476-1
available as accessory) after fitting.
3.2 Mounting of the actuator
See operating instructions Actuator.
The actuator must be permanently fitted to the safety guards and protected
against displacement by suitable measures (tamperproof screws, gluing,
drilling of the screw heads).

3.3 Dimensions
All measurements in mm.
Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by authorised personnel in a
de-energised condition.
The contact labelling can be found in the wiring compartment of the switch.
Appropriate cable glands with a suitable degree of protection are to be used.
Settle length x of the conductor: 6 mm
After wiring, dust and soiling must be removed from the wiring compartment.
The safety switch is double insulated.
The use of a protective ground connector therefore is not authorised.
4.2 Contact Options
Contacts are shown with safety guard closed. All NC contacts have positive
break B.
Set-up and maintenance
The safety function of the safety components must be tested. In the case of correct installation and adequate use, the safety switchgear features maintenance-free functionality. A regular visual inspection and functional test, including the following steps, is recommended:
- Check for free movement of the actuating element
- Check cable entry and connections
- Check the switch enclosure for damage
- Remove particles of dust and soiling
Adequate measures must be taken to ensure protection against tampering either
to prevent tampering of the safety guard, for instance by means of replacement
actuators.
Damaged or defective components must be replaced.
Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised condition only.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
