1.3 Explanation of the symbols used
Information, hint, note:
This symbol is used for identifying useful additional information.
Caution: Failure to comply with this warning notice could
lead to failures or malfunctions.
Warning: Failure to comply with this warning notice could
lead to physical injury and/or damage to the machine.
1.4 Appropriate use
The products described in these operating instructions are developed to
execute safety-related functions as part of an entire plant or machine. It
is the responsibility of the manufacturer of a machine or plant to ensure
the correct functionality of the entire machine or plant.
The safety switchgear must be exclusively used in accordance with
the versions listed below or for the applications authorised by the
manufacturer. Detailed information regarding the range of applications
can be found in the chapter "Product description".
1.5 General safety instructions
The user must observe the safety instructions in this operating
instructions manual, the country specific installation standards as well
as all prevailing safety regulations and accident prevention rules.
Further technical information can be found in the Schmersal
catalogues or in the online catalogue on the Internet:
www.schmersal.net.
The information contained in this operating instructions manual is
provided without liability and is subject to technical modifications.
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.
The entire concept of the control system, in which the safety
component is integrated, must be validated to EN ISO 13849-2.
There are no residual risks, provided that the safety instructions as well
as the instructions regarding mounting, commissioning, operation and

1.6 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. The relevant
requirements of the standard EN 1088 must be observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this 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. 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.

3.3 Adjustment
In the unlocked condition, the safety guard is kept in a closed condition
by the adjustable ball latch. By rotating a hexagonal key wrench
clockwise, the desired holding force can be increased; if the hexagonal
key wrench is rotated counterclockwise, the holding force is decreased.
The holding force must always be set as low as possible.
4. Rear side 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.
Connection and sealing
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. Non-used input openings must be
sealed by means of threaded plugs. After wiring, dust and soiling must
be removed from the wiring compartment. Maximum tightening torque
for the screws: cover 0.6 + 0.1 Nm; bottom cover 0.7 + 0.1 Nm.
The conductors of the connecting cables must not obstruct the
movement of the switching lever.
4.2 Contact variants
Contacts are shown with safety guard closed.
