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 non-contact, electronic safety switchgear is designed for application in safety circuits and is used for monitoring
the position and locking of movable safety guards.
FThe safety switchgears are classified according to EN ISO 14119 as type 4 interlocking devices. Designs with individual coding
are classified as highly coded.
The different variants can be used as safety switch with interlocking function either as solenoid interlock.
2If the risk analysis indicates the use of a monitored interlock then a variant with the monitored interlock is to be used,
marked with the > symbol in the ordering code.
The actuator monitoring variant (B) is a safety switch with an interlock function for process protection.
The safety function consists of safely switching off the safety outputs when the safety guard is unlocked or opened and
maintaining the safe switched off condition of the safety outputs for as long as the safety guard is open.
2Interlocks with power to lock principle may only be used in special cases after a thorough evaluation of the accident risk, since
the safety guard can be opened immediately on failure of the power supply or upon activation of the main switch.
Series-wiring
Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction time
increases by the sum of the reaction time of the inputs per additional unit specified in the technical data. The quantity
of devices is only limited by the cable drops and the external cable fuse protection, according to the technical data. Up
to 31 device variants with serial diagnostics can be wired in series.

2The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety level. If
multiple safety sensors are involved in the same safety function, the PFH values of the individual components must be added.
2The 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
2In 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.

Note about the safety classification
2The safety consideration of the guard locking function only applies for standard devices with monitored solenoid interlock
AZM300Z-…-1P2P-… (see Ordering code). A safety assessment of the guard locking function for devices with serial diagnostics
"SD2P" is not allowed due to the non-safe locking/unlocking signal from the SD Gateway.
2If for a certain application the power to unlock version of a solenoid interlock cannot be used, for this exception an interlock
with power to lock can be used if additional safety measure need to be realised that have an equivalent safety level.

2The safety analysis of the guard locking function refers to the component solenoid interlock AZM as part of the complete
system.
On the customer side further measures such as safe actuation and safe cable installation to prevent faults are to be
implemented.
In the event of a fault resulting in the unlocking of the guard locking, this is detected by the solenoid interlock and the safety
gates Y1/Y2 switch off. When such a fault occurs the protection equipment may open immediately, just once, before the safe
condition of the machine is reached. The system reaction of category 2 allows that a fault can occur between tests causing the
loss of the safety function which is detected by the test.
2The actuation of the interlock must be compared externally with the OSSD release. If a shut-down now occurs due to an
unintentional unlocking this is detected by an external diagnostic.

3 Mounting
3.1 General mounting instructions
2Please observe the remarks of the standards EN ISO 12100, EN ISO 14119 and EN ISO 14120.
For the correct fixing of the solenoid interlock and the actuator, two mounting holes for M6 screws are provided
(tightening torque: 6 … 7 Nm).
Any mounting position. The system must only be operated with an angle of ≤ 2° between the solenoid interlock and the
actuator.

FThe solenoid interlock can be used as an end stop. Dependant upon the door weight and the actuating speed, the mechanical
life could be reduced.
Mounting of the solenoid interlock and the actuator
Refer to the mounting instructions manual for the corresponding actuator.
2The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).
Actuating directions

The diagrams show a closed guard system with a set latching force of 50 N (see also chapter "adjustment of latching
force").
2Provide for a sufficient insertion of the actuator into the rotary handle.
Correct
False
To avoid any interference inherent to this kind of system and any reduction of the switching distances, please observe
the following guidelines:
The presence of metal chips in the vicinity of the solenoid interlock is liable to modify the switching distance
Keep away from metal chips
Minimum distance between two solenoid interlocks
as well as other systems with same frequency (125 kHz)

The minimum distance from metallic securing surfaces to the face side "A" and underside "B" of the device is 5 mm.
3.2 Manual release
For the machine set-up, the solenoid interlock can be unlocked in a de-energised condition. The solenoid interlock is
unlocked by turning the manual release in the position q The normal locking function is only restored after the
manual release has been returned to its original position

p.
Caution: do not turn beyond the end stop!
Key
A: connector plug M12, 8-pole
B: LED display
C1: Manual release by means of slotted screwdriver
C2: Manual release by means of triangular key TK-M5
The manual release must be protected against accidental actuation, e.g. by using the enclosed seal after completing
commissioning.
3.3 Emergency exit -T/-T8 or emergency release -N
With variants that have both emergency exit and emergency release, the red lever is loosely supplied. Before first use,
mount the lever on the triangular part of the release using the screw supplied so that the arrow in the triangle and pin
on the red lever are congruent.
The installation of the lever is possible on both sides. The opposite side can be used as a manual release by means of a
triangular key TK-M5.

2Reset of the manual release by actuating the red emergency exit lever must be prevented by the user.
2Emergency exit (-T/-T8)
(fitting and actuation only from within the hazardous area)
To activate the emergency exit, turn the red lever in the direction of the arrow to the end stop. The safety outputs
switch off and the guard system can be opened. The blocked position is cancelled by turning the lever in the opposite
direction. In the unlocked position, the guard system is secured against unintentional locking.
2Emergency release (-N)
Fitting and actuation only from outside the hazardous area. 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 turn the red lever in the direction of the arrow to the end stop. The safety outputs
switch off and the guard system 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.
FTo ensure correct operation of emergency exit -T/-T8 and emergency release -N, the safety door/guard must not be in a
mechanically tensioned state.
2It is possible to combine an emergency exit with an emergency release. Please note that when the red lever is actuated, the
opposite lever also rotates. As such, the procedure outlined above must be followed to release the emergency release lever.
3.4 Mounting with mounting plate
For doors, which close flush with the door frame, the optional mounting late MP-AZ/AZM300-1 can be used.
