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.
3-22

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 different variants can be used as safety switch with interlocking function either as solenoid interlock.
2If the risk analysis indicates the use of a monitored interlock then a variant with the monitored interlock is to be used,
marked with the > symbol in the ordering code.
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.
2Interlocks 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. In the case of a series connection, the risk time remains unchanged and the reaction
time increases by the sum of the reaction time of the inputs per additional unit specified in the technical data. The
quantity of devices is only limited by the cable drops and the external cable fuse protection, according to the
technical data. Up to 31 device variants with serial diagnostics can be wired in series.
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.
2.4 Warning about misuse
2In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant
components cannot be excluded. There are no residual risks, provided that the safety instructions as well as the
instructions regarding mounting, commissioning, operation and maintenance are observed.
2.5 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply
with the operating instructions manual. The manufacturer shall accept no liability for damages resulting from the
use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the
device are strictly forbidden, the manufacturer shall accept no liability for damages resulting from such invasive

Note about the safety classification
2Die Sicherheitsbetrachtung der Zuhaltefunktion ist nur für Standardgeräte mit überwachter Zuhaltefunktion AZM201Z-...-
1P2PW-... gültig (vgl. Typenschlüssel). Eine Sicherheitsbetrachtung der Zuhaltefunktion für Geräte mit serieller Diagnose
„SD2P" ist aufgrund des nicht-sicheren Sperr-/Entsperrsignals durch das SD-Gateway nicht zulässig.
2If for a certain application the power to unlock version of a solenoid interlock cannot be used, 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.
2The 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.
2The actuation of the interlock must be compared externally with the OSSD release. If a shut-down now occurs due to an
unintentional unlocking this is detected by an external diagnostic.
UL notice
Use isolated power supply only. For use in NFPA 79 Applications only. Adapters providing field wiring means are
available from the manufacturer. Refer to manufacturers information.

5 Anlernen der Betätiger / Betätigererkennung
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).
15-22

3. After 10 seconds, brief yellow cyclic flashes (3 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. Once the operating voltage is switched back on, the actuator must be detected once more in order to
activate the actuator code that has been taught in. In this way, the activated code is definitively saved!
For ordering suffix -I1, the executed allocation of safety switchgear 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 Active principle and diagnostic functions
6.1 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.
6.2 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.
It is not necessary to open the safety guard.
In the B-variant AZM201B, the opening of the safety guard causes
the safety outputs to be disabled.
6.3 Diagnostic-LEDs
Die Sicherheitszuhaltung signalisiert den Betriebszustand, aber auch Störungen, über drei verschiedenfarbige LEDs
auf der Frontseite des Gerätes.
green (Power) Supply voltage on
yellow (Status) Operating condition
red (Fault) Error (see table 2: Error messages / flash codes red diagnostic LED)
6.4 Solenoid interlock with conventional diagnostic output
The short-circuit proof diagnostic output OUT can be used for central visualisation or control tasks, e.g. in a PLC.
The diagnostic output is not a safety-related output.
Error
Errors which no longer guarantee the function of the safety switchgear (internal errors) cause the safety outputs to
16-22

be disabled within the duration of risk. After fault rectification, the error message is reset by opening and re-closing
the corresponding safety guard.
FAutomatic, 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
interlock, the solenoid interlock must be isolated from the supply voltage after elimination of the error causes.
Fault warning
A fault that does not immediately endanger the safety function of the safety switchgear (e.g. too high ambient
temperature, safety output at external potential, cross-circuit) leads to delayed shutdown (see Table 2). This signal
combination, diagnostic output disabled and safety channels still enabled, can be used to stop the production
process in a controlled manner. An error warning is deleted when the cause of error is eliminated. If the fault
warning remains on for 30 minutes, the safety outputs are also switched off (red LED flashes, see Table 2).

6.5 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 slave in an existing field bus system. In this way, the diagnostic signals can be evaluated by means of
a PLC.
The necessary software for the integration of the SD-Gateway is available for download at products.schmersal.com.
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 SD-gateway and
the solenoid interlock, the switching condition of the solenoid interlock is maintained.
Error
Errors which no longer guarantee the function of the safety switchgear (internal errors) cause the safety outputs to
be disabled within the duration of risk. 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.
FAutomatic, 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
interlock, the solenoid interlock must be isolated from the supply voltage after elimination of the error causes.
