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
The solenoid interlock has been designed to prevent in conjunction
with the control part of a machine, movable safety guards from being
opened before hazardous conditions have been eliminated. The AZM
161 I solenoid interlocks with individual coding offer a higher protection
against tampering.
Interlocks with the power to lock principle may only be used
in special cases after a thorough evaluation of the accident
risk, since the guarding device can immediately be opened
on failure of the electrical power supply or when the main
switch is opened.
The safety switchgear units are classified as type 2 inter-
locking devices in accordance with ISO 14119 and are rated
as highly coded.
Manual release
(for set-up, maintenance, etc.)
The manual release is realised by turning the triangular key, so that the
locking bolt is pulled into the unlocking position. The normal locking
function is only restored after the triangular key has been returned to
its original position. After being put into operation, the manual release
must be secured by installing the plastic cover, which is included in
delivery.
Lateral manual release Manual release on the
cover side or on the rear side
(ordering suffix -ED/-EU)
Triangular key TK-M5 (101100887) available as accessory.
Emergency release (ordering suffix -N)
(mounting only on the outside of the safety guard)
The emergency release should only be used in an emergency.
The solenoid interlock should be installed and/or protected so
that an inadvertent opening of the interlock by an emergency
release can be prevented.
The emergency release must be clearly labelled that it should
only be used in an emergency. The label can be used that
was included in the delivery.
To activate the emergency release in case of an emergency, the orange
lever must be turned to the stop in the direction marked by the arrow.
In this position, the safety guard can be opened. The lever is latched
and cannot be returned to its original position. To cancel the blocking
condition, the central mounting screw must be loosened to such extent
that the lever can be turned back into its original position. The screw
must then be re-tightened.

Emergency exit
(Fitting and actuation only from within the hazardous area)
To activate the emergency exit of the T version in case of an emergency,
the orange lever must be turned to the stop in direction marked by
the arrow. The emergency exit function of the TD and TU versions is
activated by pressing the red pushbutton.
In this position, the safety guard can be opened. The blocking condition
is cancelled by turning the lever in opposite direction or by pulling back
the pushbutton. In unlocked position, the safety guard is protected
against unintentional closing.
Lateral emergency exit
(ordering suffix -T)
Emergency exit on the
cover side or on the rear side
(ordering suffix -TD/-TU)
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.

If multiple safety components are wired in series, the Performance
Level to ISO 13849-1 will be reduced due to the restricted error
detection under certain circumstances.
3. Mounting
3.1 General mounting instructions
On delivery, the actuator is in inserted condition. For
power-to-unlock components, the actuator must be released
by means of the manual release. If the triangular key is
turned 180°, the locking bolt is pulled into the unlocking
position. The normal locking function is only restored after
the triangular key has been returned to its original position.
Three mounting holes are provided for fixing the enclosure. The
solenoid interlock is double insulated. The use of an earth wire is not
authorised. The solenoid interlock 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. Unused
actuator openings must be sealed with slot sealing plugs.
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).
Please observe the remarks of the standards ISO 12100,
EN 953 and ISO 14119.

3.3 Mounting of the actuator
The marks on the used actuator opening of the solenoid
interlock and on the actuator must be opposite.
Use tamper-proof screws (available as accessory) to prevent
unauthorised unscrewing. Please observe that, when fixing the switch
e.g. by means of rivetting or welding, the insertion depth of the actuator
is not modified. Different actuator models are available: for sliding and
removable safety guards, preferably use the AZM 161-B1 and
AZM 161-B1E actuator. For hinged guards, the AZM 161-B6L or
AZM 161-B6R actuator.
When the switch is fitted on a hinged safety guard, please ensure that
the point of rotation is located within the range of the upper surface of
the safety switch, in which the actuator hook is inserted (refer to table).

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.
If the risk analysis indicates the use of a monitored interlock
they are to be connected in the safety circuit with the
contacts indicated with the symbol .
Appropriate cable glands with a suitable degree of protection are to
be used. Remove the thin walls of the mounting holes by inserting the
cable entry.
Puncturing the wall of the holes with auxiliary tools
(e.g. screwdriver) can cause damage.
4.2 Contact variants
Contacts are shown in the de-energised condition and with the actuator
inserted.

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. Fitting of the solenoid interlock and the actuator
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 for tight installation of the actuator and the switch
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.
