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 first of the two safety functions is the safe shut-down of both safety outputs when unlocking or opening the
guard system and making sure that the switched-off position is maintained when the guard system is open or
unlocked (locking function). The second safety function (interlocking function) is the safe interlocking of a guard
system which was locked only once. The locking of the guard system may only be switched off when there is no
fault and a valid signal to unlock is present.
When the guard system is closed and there is a valid two-channel control signal applied by the user or through the
controller, the locking bolt of the AZM400 can be driven out. As soon as the locking bolt have reached sufficient
depth in the locking hole the guard system is considered to be safely locked.
The AZM400 solenoid interlock is a bi-stable system, which means the interlock remains in the last position if power
is lost.
4-27

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.

3 Mounting
3.1 General mounting instructions
2Please observe the remarks of the standards EN ISO 12100, EN ISO 14119 and EN ISO 14120.
Any position is possible.
2The accumulation of fine-grained dirt in the bolt area must be avoided.
In such a case it is therefore not advised to have vertical mounting, where the bolt goes upwards from below.
For the correct fixing of the solenoid interlock, the device is provided with two mounting holes for M6-screws.
2The M6 screws should have at least the strength class 10.9. The tightening torque of the M6 screws is 8 Nm.
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).
10-27

2Use in temperatures below freezing is permitted only with dry cold. The customer must take this into account when
assembling the safety switch.
Actuating directions and switch distances
The AZM400 can be operated within the following tolerance limits:
X axis ± 4 mm
Y axis ± 4 mm
Z axis Distance between actuator and solenoid interlock 1…7 mm with
max. angle offset of 2°
FThe actuating curves show the typical detection range of the actuator depending on the actuating direction.

2The approach direction must only be from the X and Y directions.
2The maximum distance of 7 mm between the actuator and the solenoid interlock must be maintained so that the stipulated
holding force and the safe clamping function is achieved according to SIL 3. The construction of the guard door is to be
designed so that it is not possible to move the guard system with the actuator on the Z axis so far that the distance
between the interlock and the actuator is greater than 7 mm.
11-27

2The safety equipment must be designed so that there is no crushing hazard due to the movement of the bolt.
Mounting of the actuators
Refer to the mounting instructions manual for the corresponding actuator.
To avoid any interference inherent to this kind of system and any reduction of the switching distances, please
observe the following guidelines:
Metal parts and magnetic fields in the area of the solenoid interlock and the actuator can influence the switch
distance or lead to malfunctions
Keep away from metal chips
Minimum distance between two solenoid interlocks
as well as other systems with same frequency (125 kHz): 30 mm
 
3.2 Manual release
For the machine set-up, the solenoid interlock can be unlocked in a de-energised condition. Turning the triangle of
the manual release using the triangular key to the q position releases the solenoid interlock. The normal locking
function is only restored after the manual release has been returned to its original position p.
Triangular key TK-M5 (101100887) available as accessory.
2Structurally, after turning back the mechanical release a mechanical release that is still active can be indicated by the LEDs
(all three LEDs flash). These will be reset after the control inputs are driven again.
2Do not turn the manual release beyond the end stop.
After successful commissioning the attached cover is to be screwed onto the manual release and then secured with
the appropriate seal. The maximum tightening torque of the cover screw is 0.55 Nm.
12-27

Locked position Unlocked position
 
3.3 Electrical manual release - E (for -ST2)
The electrical manual release can be achieved with an additional auxiliary power supply. The auxiliary power supply
unit H1 is for this purpose.
The AZM400 should only be supplied with the auxiliary power supply, this is so the locking bolt can be released
independently of the control inputs.
Then no other actions are required, the safety and diagnostic units remain off.
System condition (only valid during the initialising phase):
Main supply Auxiliary supply System condition
0 V 0 V Locking bolt remains in position (safety
outputs switched off)
24 V 0 V dependent on the control inputs
0 V 24 V Locking bolt is retracted automatically
(unlock)
24 V 24 V Locking bolt remains in position (fault)
2The wiring and actuation of the electrical manual release is to undergo a technical safety validation. The signal from the
auxiliary power supply via UPS is then processed differently and internally so that short-circuits can be detected.
3.4 Emergency exit -T
Emergency exit for use within the hazardous area.
To activate the emergency exit, turn the red lever in the direction of the arrow to the end stop. The bolt moves due
to spring force to the unlocked position so that the guard system can be opened in this position and the safety
outputs switch off. In the unlocked position, the guard system is secured against unintentional locking.
2Do not turn beyond the end stop.
Locked position Unlocked position

2To ensure correct operation of emergency exit -T the safety door/guard must not be in a mechanically tensioned state.
3.5 Assembly with mounting set
When using 40 mm aluminium profile, the optimum mounting set MS-AZM400 can be used. This consists of two
mounting plates including four bolt and four nuts.

4 Electrical connection
4.1 General information for electrical connection
2The electrical connection may only be carried out by authorised personnel in a de-energised condition.
The voltage inputs A1 (and H1 with the AZM400Z-ST2..), and the control inputs E1, E2 and E3 must have a
permanent protection against over-voltage. The use of PELV supply units according to EN 60204-1 is recommended.
The safety outputs can be integrated into the safety circuit of the control system.
The required electrical cable fuse protection must be integrated in the installation.
4.2 Control options in the normal operating mode
Due to the control inputs E1, E2 and E3 for controlling the guard locking function it is possible to use different
control options to be able to drive the AZM400 with a different safety controller. The function of the control inputs is
the same for both ST and ST2 versions. Setting the operational control inputs according to the following table
causes the interlock to unlock.
Input condition Version P/P Version P/N
 E1 E2 E3 E1 = E2 E3
Lock open open GND open open
Unlock 24 V 24 V GND 24 V GND
Use of safety outputs of the type P/P:
safety controller
18-27

Use of safety controls of the type P/N:
safety controller 
2The outputs used for the control must correspond to the Performance Level (PL) of the guard system. To achieve the PL e
the control must have tested outputs as these are not tested by the AZM400.
2Independent of the version used, the notes in the Operating Instructions of the used controller should be observed.
These could include:
- Shielded installed cable
- Minimum interval every 24 hours
- etc.
Block drive
If the locking bolt does not reach the "locked" condition with the first attempt, the AZM400 makes an autonomous
attempt. If the second attempt also fails, the AZM400 signals a fault (comp. table 2).
After a malfunction, condition of the control inputs has to be changed to allow the locking bolt to be driven out
again.
When the guard system closes slowly, a block drive can occur if the actuator that is opening is not in front of the
bolt being driven out (see Chapter "Operating equipment and distances").
Unlocking after Power On
If after switching on, the AZM400 is already in the locked position, the device must first be unlocked and then
locked again. This is to verify the causality of the drive signals and to check the sufficient depth of the locking bolt.
The yellow LED flashes after power-on in the locked position.
4.3 Requirements for the connected safety-monitoring module
Dual-channel safety input, suitable for 2 p-type semi-conductor outputs (OSSD)
19-27

The solenoid interlock cyclically switch off the safety output to test them. The safety-monitoring module therefore
does not need to be equipped with a cross-wire short detection. The test impulse time of ≤ 0.4 ms must be
tolerated by the evaluation. The test impulse, the switch-off time of the solenoid interlock can be extended
depending on the cable length and the capacity of the cable used.
FSafety controller configuration
If the solenoid interlock is connected to electronic safety-monitoring modules, we recommend that you set a discrepancy
time of 100 ms. The safety inputs of the safety-monitoring module must be able to blank a test impulse of < 1 ms.
FInformation for the selection of suitable safety-monitoring modules can be found in the Schmersal catalogues or in the
online catalogue on the Internet: products.schmersal.com.
