2. Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
AZ 15 ZO
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 Destination and use
Safety switches with separate actuators are suitable for use on inter-
locking mechanisms, such as elevator door locks or elevator doors,
which need to be closed 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 in the safety switch
are positively opened.
The safety switchgears are classified according to
ISO 14119 as type 2 switching 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.

3. Mounting
3.1 General mounting instructions
The mounting dimensions are indicated on the rear of the component.
The safety switch and the actuator must be fitted in a concealed
mounting position in order to avoid a neutralisation of the safety
switch's function by simple means.
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.
Please observe the remarks of the standards ISO 14119,
EN 81-20 and EN 81-50.
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).

4. 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. For the cable entry, suitable cable glands with an appropriate
degree of protection must be used. 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 variants
Contacts are shown with safety guard closed.

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested.
The following conditions must be previously checked and met:
1. Check the free movement of the actuating element
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage
5.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the free movement of the actuating element
2. Remove particles of dust and soiling
3. Check cable entry and connections
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.
6. 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.
