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. Serieswiring 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.

The safety consideration of the guard locking function only applies for standard devices with monitored solenoid interlock AZM201Z-…-1P2PW-… (see Ordering code). A safety assessment 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

Solenoid interlock

AZM201

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

3.2 Manual release

For the machine set-up, the solenoid interlock can be unlocked in a deenergised 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.

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).

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 safetymonitoring 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 safetymonitoring modules, we recommend that you set a discrepancy time of 100 ms. The safety inputs of the safetymonitoring 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.

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.

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.

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.

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.

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.

Error warning

Diagnostic error (warning)

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

Accessories for the series-wiring

To provide for a comfortable wiring and series-wiring of SD components, the connectors and the SD-2V-F-SK SD junction boxes (variant for the field in closed enclosure) and SD-2V-S-SK (variant for DIN rail mounting in the control cabinet) are available.

On wiring SD devices, please pay attention to the voltage drop on the cables and the current carrying capacity of the individual components.

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.
