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”.

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 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.

Warning: If 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.
• 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. 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.

Warning

• 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.

Warning about misuse

In 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.

Exclusion of liability

Note about the safety classification

Warning

• The safety classification of the guard locking function only applies for standard devices with monitored solenoid interlock AZM201Z-…-1P2PW-… (see Ordering code). A safety classification of the guard locking function for devices with serial diagnostics “SD2P” is not allowed due to the non-safe locking/unlocking signal from the SD Gateway

• If 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.

• 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.

• The 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.

Serial diagnostic -SD

Tips

• The fitted 24V, X1, X2 bridge is included in the delivery of …-1P2PW and …-SD2P.
• On wiring SD devices, please pay attention to the voltage drop on the cables and the current carrying capacity of the individual components.

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, products.schmersal.com.

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 AZM201 … 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 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 safetymonitoring module). The safety outputs of the first safety component are wired to the safety-monitoring module.

• Y1 and Y2 = Safety outputs → Safety monitoring module

Wiring example 2: Series-wiring of the AZM201 with serial diagnostic function (max. 31 components in series)

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. The safety outputs of the first safety component are wired to the safety-monitoring module. The serial Diagnostic Gateway is connected to the serial diagnostic input of the first safety component.

• Y1 and Y2 = Safety outputs → Safety monitoring module
• SD-IN → Gateway → Field bus

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 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.

Active principle and diagnostic functions

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.

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.

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.

LED)

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 be disabled within the duration of risk. After fault rectification, the error message is reset by opening and reclosing the corresponding safety guard.

Tip: 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 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).

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.

Tip: 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 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.

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
5. Remove particles of dust and soiling.

Warning

• 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.

Disassembly and disposal

Disassembly

• The safety switchgear must be disassembled in a de-energised condition only.

Disposal

• The safety switchgear must be disposed of in an appropriate manner in accordance with the national prescriptions and legislations.
