The 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
The actuation of the interlock must be compared with the
external OSSD enabler. If a shut-down now occurs due to
an unintentional unlocking this is detected by an external
diagnostic.
If for a certain application the power to unlock version of a
solenoid interlock cannot be used, then 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.
The 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.
3. Mounting
3.1 General mounting instructions
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and 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.

The 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.
The actuator must be permanently fitted to the safety guard
and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads,
pinning).
Actuating directions
The diagrams show a closed guard system with a set latching force of
50 N (for adjustment of latching force, see chapter 5.4).
Provide 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.
