If the risk analysis indicates the use of a monitored interlock
then a variant with the monitored interlock is to be used,
labelled with the
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.
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.
Emergency 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

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.
Series-wiring
Series-wiring can be set up. The response and risk times are not
altered by wiring in series. The number of components is only limited
by the external cable protection according to the technical data and
the line loss. Series-wiring of up to 31 AZM300 … SD components with
serial diagnostics is possible. In devices with the serial diagnostics
function (ordering suffix -SD), the serial diagnostics connections
are wired in series and connected to a SD Gateway for evaluation
purposes. Wiring examples for series-wiring, refer to appendix.
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.

The safety consideration of the guard locking function
only applies for standard devices with monitored solenoid
interlock AZM300Z-…-1P2P-… (see Ordering code).
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 quiescent current 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.

3.1 General mounting instructions
For the correct fixing of the solenoid interlock and the actuator, two mounting holes for M6 screws are provided (tightening torque: 5 … 6 Nm).
Any mounting position. The system must only be operated with an
angle of ≤ 2° between the solenoid interlock and the actuator. When
mounting the solenoid interlock onto metallic surfaces, a galvanic connection must be realised between the mounting surface and fixing point "A".
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
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.
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
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.
Observe the minimum distance between two solenoid interlocks

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.

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.
The voltage inputs A1, X1, X2 and IN must have a protection against
permanent overvoltage. supply units according to IEC 60204-1 is
recommended.
The safety outputs can be integrated in the safety circuit of the control
system.
Requirements for the connected safety-monitoring module:
• Dual-channel safety input, suitable for p-type semi-conductor outputs
Configuration of the safety-monitoring module
If the safety sensor is connected to electronic safety-monitoring modules, we recommend that you set a discrepancy time
of min. 100 ms. The safety inputs of the safety-monitoring
module must be able to blank a test impulse of approx. 1 ms.
The safety-monitoring module does not need to have a crosswire short monitoring function, if necessary, the cross-wire
short monitoring function must be disabled.
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.
Cable design in case of serial diagnostics
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 and the delayed shutdown of the
safety outputs. The safety outputs are disabled if the error warning
is active for 30 minutes. The signal combination, diagnostic output
disabled and safety channels still enabled, can be used to stop the
production process in a controlled manner. After the rectification of
the error, the error message is reset by opening the corresponding
safety guard. For devices with serial diagnostic, a bit can be set/
deleted in the call telegram to reset the fault.
5.3 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 (3 Hz) request the switch-off
of the operating voltage of the solenid interlock. (If the voltage is not
switched off within 5 minutes, the solenoid interlock cancels the "teachin" 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 thus executed allocation of safety switchgear
and actuator is irreversible.
When wiring SD devices, please observe the voltage drop on
the cables and the current carrying capacity of the individual
components.
The wiring capacity of the connecting cable of the solenoid interlock
must not exceed 50 nF. Depending on the strand structure, normal
unshielded 30 m long control cables LIYY 0.25 mm² to 1.5 mm² have a
wiring capacitance of approx. 3 … 7 nF.
Accessories SD interface
For ease of wiring and series-wiring of SD devices,
considerable accessories are available. Detailed information
is available on the Internet, www.schmersal.net.
5. Operating principles, coding and latching force
5.1 Magnet control
In the power to unlock version of the AZM300, the solenoid interlock is
unlocked when the IN signal (= 24V) is set. In the power to lock version
of the AZM300, the solenoid interlock is locked when the IN signal
(= 24 V) is set.
5.2 Mode of operation of the safety outputs
In the standard AZM 300Z variant, the unlocking of the solenoid
interlock causes the safety outputs to be disabled. The unlocked
safety guard can be relocked as long as the actuator is inserted in the
AZM 300Z solenoid interlock; in that case, the safety outputs are
re-enabled. The safety guard must not be opened.
In the AZM300B version, only the opening of the safety guard causes
the safety outputs to be disabled.
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.
5.4 Latching force adjustment
In order to enable trouble-free functionality of the device, the rotary
handle must be in position I or II when the safety guard is open. In the
intermediate positions, locking is impossible.
The latching force is changed by turning the rotary handle by 180°.
In position I,the latching force is approx. 25 N.
In position II, the latching force is approx. 50 N.

6.2 Solenoid interlock with conventional diagnostic output
The short-circuit proof diagnostic output OUT can be used for central
visualisation or control functions, e.g. in a PLC.
The diagnostic output is not a safety-related output!
Error
Errors, which no longer guarantee the function of the solenoid interlock
(internal errors) cause the safety outputs to be disabled immediately.
Any error that does not immediately affect the safe functionality of the
AZM300 solenoid interlock (e.g. cross-wire short, temperature error,
safety output, short circuit to +24 VDC) 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.
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. This enables the shutdown of the process in a
controlled manner. An error warning is deleted when the cause of error
is eliminated.

6.3 Solenoid interlock with serial diagnostic function SD
Solenoid interlocks with serial diagnostic cable have a serial input and
output cable instead of the conventional diagnostic output. If solenoid
interlocks are wired in series, the diagnostic data are transmitted
through the series-wiring of the inputs and outputs.
Max. 31 solenoid interlocks can be wired in series. For the evaluation of
the serial diagnostics line either the PROFIBUS-Gateway SD-I-DP-V0-2
or the Universal-Gateway SD-I-U-... are used. This serial diagnostic
interface is integrated as a slave in an existing field bus system. In this
way, the diagnostic signals can be evaluated by means of a PLC.
The response data and the diagnostic data are automatically and permanently written in an input byte of the PLC for each solenoid interlock
in the series-wired chain. The request data for each solenoid interlock
is transmitted to the component through an output byte of the PLC. In
case of a communication error between the field bus gateway and the
solenoid interlock, the switching condition of the solenoid interlock is
maintained.

A fault has occured, which causes the safety outputs to be disabled.
The fault is reset, when the cause is eliminated and bit 7 of the request
byte changes from 1 to 0 or the safety guard is opened. Faults at the
safety outputs are only deleted upon the next release, as the fault rectification cannot be detected sooner.
Error warning

If more than one fault is detected at the safety outputs, the
AZM 300 will be electronically locked and a normal fault
reset will no longer be possible. To reset this type of interlocking, the AZM 300, must be isolated from the power supply
after elimination of the error causes.

The leading diagnosis message through bit 1 indicates whether locking or unlocking of the guard system is possible.
The solenoid interlock cannot be unlocked if e.g. the door pulls the turret out of its rest position beyond the set latching force. This can occur if
doors are heavily distorted or when pulling the door.
The solenoid interlock can only be locked if the turret is in the rest position, i.e. the latching force is sufficient to pull the guard system into the
correct position.

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. angular misalignment (see “Mounting” part)
3. Fitting and integrity of the cable connections.
4. Check the switch enclosure for damage.
5. Remove particles of dust and soiling.
6. For variants with an emergency exit and emergency release, the
following is to be considered:
• For variants with emergency exits it should be possible to open the
safety guard inside the hazardous area; it should not be possible to
lock the safety guard from inside.
• By operating the emergency release lever outside of the hazardous
zone it must be possible to open the guard system.
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:
• Check for a secure installation of the actuator and the
solenoid interlock
• Check max. axial misalignment of actuator and solenoid interlock.
• Check max. angular misalignment (see “Mounting” part)
• Fitting and integrity of the cable connections.
• Check the switch enclosure for damages
• Remove soiling
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.
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.
9. Appendix
9.1 Wiring examples
The application examples shown are suggestions. They however do not release the user from carefully checking whether the switchgear and
its set-up are suitable for the individual application.
Wiring example 1: Series-wiring of the AZM300 with conventional diagnostic output
The voltage is supplied at both safety inputs of the terminal safety component of the chain (considered from the safety-monitoring module).
The safety outputs of the first safety component are wired to the safety-monitoring module.
