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.
FSpecial information or information deviating from the standard on special versions can be found in the concluding chapter
"Appendix – Special versions".
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.
F
The safety switchgears are classified according to ISO 14119 as type 4 interlocking devices. Designs with individual coding are classified as
highly coded.
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.
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.

Der Aufbau einer Reihenschaltung ist möglich. Bei einer Reihenschaltung bleibt die Risikozeit unverändert und die
Reaktionszeit erhöht sich um die Summe der in den technischen Daten angegebenen Reaktionszeit der Eingänge pro
zusätzlichem Gerät. Die Anzahl der Geräte ist lediglich durch die Leitungsverluste und die externe Leitungsabsicherung,
gemäß den technischen Daten, begrenzt. Eine Reihenschaltung von AZ201 ... SD mit serieller Diagnosefunktion ist bis
zu einer Anzahl von 31 Geräten möglich.

5 Actuator teaching / actuator detection
14-21

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 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 Mode of operation of the safety outputs
Das Öffnen der Schutzeinrichtung führt zur Abschaltung der Sicherheitsausgänge innerhalb der Risikozeit.
6.2 Diagnostic-LEDs
Der Sicherheitsschalter 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)
6.3 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.
Wenn die Tür geschlossen und der Betätiger eingeführt ist, wird dies mit einem 24 V Signal angezeigt.
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 be
15-21

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).

6.4 Sicherheitsschalter mit serieller Diagnosefunktion SD
Sicherheitsschalter mit serieller Diagnoseleitung verfügen anstelle des konventionellen Diagnoseausgangs über eine
serielle Ein- und Ausgangsleitung. Werden Sicherheitsschalter in Reihe geschaltet, werden über die Reihenschaltung
dieser Ein- und Ausgangsleitungen Diagnosedaten übertragen.
Es können bis zu 31 Sicherheitsschalter in Reihe geschaltet werden. Zur Auswertung der seriellen Diagnoseleitung wird
entweder das PROFIBUS-Gateway SD-I-DP-V0-2 oder das Universal-Gateway SD-I-U-… eingesetzt. Dieses serielle
Diagnose-Interface wird als Slave in ein vorhandenes Feldbus-System eingebunden. Die Diagnosesignale können auf
diese Weise mit einer SPS ausgewertet werden.
The necessary software for the integration of the SD-Gateway is available for download at products.schmersal.com.
Die Antwortdaten und die Diagnosedaten werden für jeden Sicherheitsschalter in der Reihenschaltungskette
automatisch und kontinuierlich jeweils in ein Eingangsbyte der SPS geschrieben. Die Aufrufdaten für jeden
Sicherheitsschalter werden über jeweils ein Ausgangsbyte der SPS an das Gerät übertragen. Tritt ein
Kommunikationsfehler zwischen dem Feldbus-Gateway und Sicherheitsschalter auf, behält der Sicherheitsschalter
seinen Schaltzustand bei.
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.
17-21

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.
Error 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. 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).
Diagnostic error (warning)
If an error (warning) is signalled in the response byte, detailed fault information can be read out.

7 Set-up and maintenance
The safety function of the safety components must be tested. 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 a secure installation of the actuator and the solenoid interlock
2. Check max. axial misalignment of actuator and solenoid interlock.
3. Fitting and integrity of the cable connections.
4. Check the switch enclosure for damages
18-21

5. Remove particles of dust and soiling.
2Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for
instance by means of replacement actuators.
2Damaged 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.
