2.4 Purpose
The non-contact, electronic solenoid interlock is designed for
application in safety circuits and is used for monitoring the position and
locking of movable safety guards.
The safety switchgears are classified according to 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.
The 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.
The 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
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
Any mounting position.
The accumulation of fine-grained contamination in the area of the bolt is
to be prevented.
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.
The M6 screws should have at least the strength class 10.9.
The tightening torque of the M6 screws is 8 Nm.
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).
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°
The actuating curves show the typical detection range of the
actuator depending on the actuating direction.
~
-26 ~+10 ~+26~-10 0 [mm]
0 ~+18~18 [mm]
X Y
1 ... 7 mm
±4 mm
Z
±4 mm
The approach direction must only be from the X and Y
directions.
The maximum distance of 7 mm between the actuator
and the solenoid interlock must be maintained so that the
stipulated clamping 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.
The safety equipment must be designed so that there is no
crushing hazard due to the movement of the bolt.
Mounting of the solenoid interlock and the actuator
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 near the safety interlock can affect the
switching distance.
• Keep away from metal chips.

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, 101100887, available as an accessory.
Structurally, 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.
Do 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 for screwing on the cover is 0.55 Nm.
Locked position: Unlocked position:
3.3 Electrical manual release - E (for -ST2)
The electrical manual release can be implemented 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 0 Locking bolt remains in position
(safety outputs switched off)
24 V 0 dependent on the control inputs
0 24 V Locking bolt is retracted automatically
(unlock)
24 V 24 V Locking bolt remains in position (fault)
The wiring and actuation of the electrical manual release is
to undergo a technical safety validation. After switching off
the main supply any cross-wire shorts of the auxiliary supply
inputs to other supply sources are not 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.
Do not turn beyond the end stop!
Locked position: Unlocked position:
To ensure correct operation of emergency exit -T the
safety door/guard must not be in a mechanically tensi-
oned 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. Rear side 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.
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 IEC 60204-1
is recommended. The safety outputs can be integrated into the safety
circuit of the control system.
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

The 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.
Independent of the version used, the notes in the Operating
Instructions of the used controller should be observed.
These could include:
- Shielded installed cable
- Minimum test 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)
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.
Configuration of the safety controller
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.
Information for the selection of suitable safety-monitoring
modules can be found in the Schmersal catalogues or in the
online catalogue on the Internet: www.schmersal.net.

Solenoid interlock AZM400

5. Operating principles and coding
5.1 Mode of operation of the safety outputs
With the solenoid interlock AZM400, the unlock signals immediately
switch off the safety outputs. The unlocked guard system can be
locked again as long as the actuator is within the detection range of the
solenoid interlock. In that case, the safety outputs are re-enabled.
If the safety outputs are already enabled, any error that does not
immediately affect the functionality of the solenoid interlock (e.g. too
high an ambient temperature, interference potential at the safety
outputs, cross-wire short) will lead to a warning message, the disabling
of the diagnostic output OUT of the ST version and OUT2 of the ST2
version and the delayed shutdown of the safety outputs. safety outputs
are disabled if the error warning is active for 30 minutes. The signal
combination, diagnostic output OUT of the ST version and OUT2 of the
ST2 version disabled and safety channels still enabled, can be used to
stop the production process in a controlled manner. After rectifying the
fault, the fault message is acknowledged by opening and closing the
associated safety door or by switching the operating voltage off and
on again.
5.2 Actuator teaching / actuator detection
Solenoid interlocks with standard coding are ready to use upon delivery.
Individually coded solenoid interlocks and actuators will require the
following "teach-in" procedure:
1. Switch the solenoid interlock's voltage supply off and back on.
2. Introduce the actuator in the detection range. The teach-in procedure
is signalled at the solenoid interlock, green LED off, red LED on,
yellow LED flashes (1 Hz).
3. After 10 seconds, brief yellow cyclic flashes (5 Hz) request the
switch-off of the operating voltage of the solenoid interlock.
(If the voltage is not switched off within 5 minutes, the solenoid
interlock cancels the "teach-in" procedure and signals a false
actuator by 5 red flashes).
4. After the operating voltage is switched back on, the actuator must
be detected once more in order to activate the taught actuator code.
In this way, the activated code is definitively saved!
For ordering suffix -I1, the executed allocation of safety interlock
and actuator is irreversible.
For ordering suffix -I2, the "teach-in" procedure for a new actuator can
be repeated an unlimited number of times. When a new actuator is
taught, the code, which was applicable until that moment, becomes
invalid. Subsequent to that, an enabling inhibit will be active for ten
minutes, thus providing for an increased protection against tampering.
The green LED will flash until the expiration of the time of the enabling
inhibit and the detection of the new actuator. In case of power failure
during the lapse of time, the 10-minutes tampering protection time will
restart.
Make organisational measures against possible manipulation
with other actuators in case that a standard coded variant is
used.
6. Diagnostic functions
6.1 Diagnostic-LEDs
The solenoid interlock signals the operating condition, as well as errors
through 3-colour LEDs.
green (Power) supply voltage on
yellow (Status)operating condition
red (Fault) Fault (see Table 2: Flash codes of the red diagnostic LED)
Arrangement of the LEDs
The short-circuit proof diagnostic output OUT or OUT1 and OUT2 of the
ST2 version can be used for central visualisation or control functions, e.g.
in a PLC. I t indicates the switching condition as shown in the table 1.
The diagnostic output OUT or OUT1 and OUT2 are not safety
relevant outputs!
Error
Errors, which no longer guarantee the safe function of the solenoid
interlock (internal error)s cause the safety outputs to be immediately
disabled. Any error that does not immediately affect the safe functionality
of the solenoid interlock (e.g. excess ambient temperature, safety output
to external potential, short circuit) will lead to a delayed shut-down (refer
to table 2). After the rectification of the error, the error message is reset
by opening the corresponding safety guard. Errors on the control inputs
do not cause the shut-down of the safety outputs.
Error warning
A fault has occurred, which causes the safety outputs to be disabled
after 30 minutes (LED "fault" flashes, see Table 2). The safety outputs
initially remain enabled (max. 30 min). This enables the shutdown of the
process in a controlled manner. An error warning is deleted when the
cause of error is eliminated.

7. Set-up and maintenance
7.1 Functional testing
The safety function of the safety components must be tested.
The following conditions must be previously checked and met:
1. Check max. axial misalignment of actuator and solenoid interlock.
2. Check max. angle displacement.
3. Make sure that it is not possible to lift the actuator in the Z axis above
the extended bolt.
4. Check for tight installation of the actuator and the switch.
5. Fitting and integrity of the cable connections.
6. Check the switch enclosure for damage.
7. Remove particles of dust and soiling.
8. For versions with emergency exit, the following should also be
considered: It must be possible to open the guard system from within
the hazardous area; it must not be possible that the guard system is
blocked from the inside.
7.2 Maintenance
In the case of correct installation and adequate use, the safety
switchgear features maintenance-free functionality.
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. Check max. axial misalignment of actuator and solenoid interlock.
3. Check max. angle displacement.
4. Make sure that it is not possible to lift the actuator in the Z axis above
the extended bolt.
5. Fitting and integrity of the cable connections.
6. Check the switch enclosure for damage.
7. Remove particles of dust and soiling.
Measures must be taken to protect against manipulation or
against the bypassing of safety device, for example, using an
extra actuator.
Damaged or defective components must be replaced.
8. Disassembly and disposal
8.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
8.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
