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
The AZM 415 solenoid interlock has been designed to prevent movable
safety guards, e.g. fences, covers or doors, in conjunction with the
control part of a machine, e.g. fail-safe delay timers or fail-safe standstill
monitors, from being opened before hazardous conditions (e.g. run-on
mouvements) have been eliminated. The AZM 415-33 includes three
switch inserts and is designed for monitoring double safety guards.
Interlocks 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.
The safety switchgears are classified according to
ISO 14119 as type 2 interlocking devices.
Power to unlock
➀➁ ➂➃ ➄
Power to unlock
without manual release
Manual release using triangular key
(only for power to unlock principle)
Solenoid interlock with manual release AZM 415-33PDKE
The manual release is only used with components that operate on the
power to unlock principle. It is used as a mounting tool and also as a
tool to open a closed and locked safety guard in case of a power failure.
The point of access to the manual release or the manual release itself
must be protected in accordance with the provisions of the professional
association, e.g. by sealing during mounting.
Unlocking: using triangular key (available as accessory)
Reset: by turning the triangular key back
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.
2.6 Safety classification of the guard locking function
If the device is used as an interlock for personal safety, a safety
classification of the guard locking function is required.
When classifying the guard locking function, a distinction must be
made between monitoring of the interlocking function and control of the
release function.
The following safety classification of the unlocking function is based on
the application of the principle of safety energy disconnection for the
solenoid supply.

3. Mounting
3.1 General mounting instructions
Four mounting holes are provided for fitting the solenoid interlock. 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. A smooth
insertion of the actuator in the enclosure must be ensured.
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
Mounting of the actuator
See actuator mounting instructions.
The actuator must be permanently fitted to the safety guards
and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).

The classification of the release function is only valid for
devices with monitored guard locking function and in the
power to unlock version (see ordering code).
A fault exclusion for the locking device of the solenoid interlock can be
assumed by a safety external energy disconnection.
In this case, the locking device of the solenoid interlock does not have
an effect on the failure probability of the unlock function.
The safety level of the unlock function is determined exclusively by the
external safety power shutdown.

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. 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 .
4.2 Connection and sealing
For the cable entry, suitable cable glands with an appropriate degree
of protection must be used. Non-used openings must be sealed by
means of threaded plugs. The switching compartment must be cleaned
(removal of cable excess etc.); put back the cover after wiring and
uniformly tighten the cover screws.
Tightening torque for the fixing screws:
- Cover: 0,6 … 0,7 Nm (AZM 415-33: 1,2 … 1,4 Nm)
- Bottom cover: 0,7 … 0,8 Nm
4.3 Contact variants

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.
