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.
- Special 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.
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 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.
- 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.

4.6 Wiring examples for 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. Series-wiring of up to 31 AZ201 … SD components with serial diagnostics is possible.
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. The application examples shown are suggestions.
Wiring example 1: Series wiring AZ201 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.

Individually coded safety switches and actuators will require the following "teach-in" procedure:
- Switch the safety switch's voltage supply off and back on.
- Introduce the actuator in the detection range. Teach-in is signalled on the safety switch, the green LED is switched off, the red LED illuminates and the yellow LED flashes (1 Hz).
- After 10 seconds, brief cyclic yellow flashes (3 Hz) request the switch-off of the operating voltage of the safety switch. (If the voltage. is not switched off within 5 minutes, the safety switch cancels the "teach-in" procedure and signals a false actuator by 5 red flashes).
- 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
The opening of the safety guard causes the safety outputs to be disabled within the risk time.
6.2 Diagnostic-LEDs
The safety switchgear signals the operational state as well as errors through three coloured LEDs installed on the front side of the device.
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.
The closed condition of the safety guard and the inserted condition of the actuator is indicated by means of a 24V signal.
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 disabled within the duration of risk. After fault rectification, the error message is reset by opening and re-closing the corresponding safety guard.
- 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 safety switch must be isolated from the power supply 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 Safety switch with serial diagnostic function SD
Safety switches with serial diagnostic cable have a serial input and output cable instead of the conventional diagnostic output. If safety switches are wired in series, the diagnostic data is transmitted through the series-wiring of the inputs and outputs.
Max. 31 safety switches 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 safety switch in the series-wired chain. The request data for each safety switch are transmitted to the component through an output byte of the PLC. In case of a communication error between the field bus gateway and the safety switch, the switching condition of the safety switch 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.
- 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 safety switch must be isolated from the power supply 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:
- Check fixation of the safety switch and the actuator.
- Check max. axial misalignment of actuator and safety switch.
- Fitting and integrity of the cable connections.
- Check the switch enclosure for damages
- Remove particles of dust and 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.
