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 Comprehensive quality insurance to 2006/42/EC
Schmersal is a certified company to appendix X of the Machinery
Directive. As a result, Schmersal is entitled to autonomously conduct
the conformity assessment procedure for the products listed in
Appendix IV of the MD without involving a notified body. The prototype
test certificates are available upon request or can be downloaded from
the Internet at www.schmersal.com.
2.4 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.
The safety switchgears are classified according to ISO 14119
as type 4 interlocking devices. Designs with individual coding
are classified as highly coded.
The different variants can be used as safety switch with interlocking
function either as solenoid interlock.
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 symbol.
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 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.
Series-wiring
Series-wiring can be set up. The risk time is 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 AZM201…-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 switchgears 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.

Operating instructions
Solenoid interlock AZM201
EN
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.
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 fitting the solenoid interlock, two mounting holes for M6 screws
with washers (washers included in delivery) are provided. 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. The unused actuator opening
must be sealed by means of the dust-proof flap (included in delivery).
Minimum distance between two solenoid interlocks
as well as other systems with same frequency (125 kHz): 100 mm.
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 guards
and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).
3.2 Manual release
For the machine set-up, the solenoid interlock can be unlocked in a de-
energised condition. After opening of the plastic flap "A" (refer to image
"Dimensions"), the triangular key must be turned clockwise to bring the
blocking bolt in unlocking condition. The normal locking function is only
restored after the triangular key has been returned to its original position.
Caution: do not turn beyond the latching point! After being put into
operation, the manual release must be secured by closing the plastic flap
"A" and affixing the seal, which is included in delivery.

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 power supply for the solenoid interlock must provide protection
against permanent overvoltage. To that effect, stabilised PELV supply
units must be used. The safety outputs can be directly integrated in the
safety circuit of the control system. For applications up to
PL e / control category 4 in accordance with ISO 13849-1, the safety
outputs of the solenoid interlock(s) must be connected to a safety-
monitoring module of the same control category (refer to wiring
examples). Inductive loads (e.g. contactors, relays, etc.) are to be
provided with suitable interference suppression circuitry.
Requirements for the connected safety-monitoring module:
• Dual-channel safety input, suitable for 2 p-type semi-conductor
outputs
Configuration of the safety controller
If the safety switchgear 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
approx. 1 ms. The safety-monitoring module does not need to
have a cross-wire 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.
If the safety component is wired to relays or to non-safety relevant
control components, a new risk analysis must be carried out.
Cable
The cable entry is realised by a metric M20 gland. This gland must be
measured by the user so that it is suitable for the cable used. A cable
gland with strain relief and suitable IP protection class must be used.
40 5
The maximum cable length is 200 m (for ST2 M12 connectors approx.
20 m depending on the cable section used for an operating current
of 0.5 A). The maximum cable section is 1.5 mm², incl. conductuor
ferrules. Prior to the connection, the cable must be stripped by
40+5 mm and insulated by 5 mm. The fitted 24V, X1, X2 bridge is
included in the delivery of …-1P2PW and …-SD2P.
Accessories for the series-wiring
For convenient wiring and series-wiring of SD components,
the SD junction boxes PFB-SD-4M12-SD (variant for the
field) and PDM-SD-4CC-SD (variant for control cabinet on
carrier rail) are available along with additional comprehensive
accessories. Detailed information is available on the Internet,
www.schmersal.net.
5. Operating principles and coding
5.1 Magnet control
In the power to unlock version of the AZM201, the solenoid interlock is
unlocked when the IN signal (= 24V) is set. In the power to lock version
of the AZM201, 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 AZM201 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 AZM201
solenoid interlock; in that case, the safety outputs are re-enabled.
The safety guard must not be opened.
In the B-variant AZM201B, the opening of the safety guard causes the
safety outputs to be disabled.
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 (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.

6. Diagnostic functions
6.1 Diagnostic-LEDs
The solenoid interlock signals the operational state as well as errors
through three coloured LED’s installed on the front side of the device.
green (Power) Supply voltage on
yellow (Status) Operating condition
red (Fault) Error (see table: Error messages /
flash codes red diagnostic LED)
6.2 Solenoid interlock with conventional diagnostic output
The short-circuit proof diagnostic output 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 error)s cause the safety outputs to be disabled within the risk
time. Any error that does not immediately affect the safe functionality of
the solenoid interlock will lead to a delayed shut-down (refer to table 2).
After fault rectification (fault at output Y1 or Y2, temperature fault), the
fault is acknowledged by opening and relocking the relevant guard door.
The safety outputs enable and allow a restart. An interlocking chain
must be permanently "locked" to enable the reactivation.
Automatic, electronic locking takes place if more than one
fault is detected at the safety outputs or a cross circuit is
detected between Y1 and Y2. This means that normal fault
acknowledgement is no longer possible. To reset this type of
interlocking, the solenoid interlock must be isolated from the
power supply after elimination of the error causes.
Error warning
A fault has occurred, which causes the safety outputs to be disabled
after 30 minutes. 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.

drop on the cables and the current carrying capacity of the
individual components.

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 is 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.
Error
A fault has occurred, 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.
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. 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
7.2 Maintenance
We recommend a regular visual inspection and
functional test, including the following steps:
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.
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.

9.1 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 AZM201 with conventional diagnostic output
In the series-wiring, the 24V-X1-X2 bridge must be removed from all components up to the last component.
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.
