For special versions, which are not listed in the ordering code, these specifications apply accordingly, provided that they correspond to the standard version.

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 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.

2

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.

2

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.

2

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.

2

The 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

2

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.

2.5 Exclusion of liability

2

The safety consideration of the guard locking function only applies for standard devices with monitored solenoid interlock AZM300Z-…-1P2P-… (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.

2

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.

2

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.

2

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.

UL notice
] This appliance is intended to be powered by a listed source of limited voltage, limited current or Class 2. This unit must be supplied with at least 24 V DC and 0.8 A via a listed (CYJV) cable/connector assembly.

3 Mounting

3.1 General mounting instructions

2

Please observe the remarks of the standards EN ISO 12100, EN ISO 14119 and EN ISO 14120.

For the correct fixing of the solenoid interlock and the actuator, two mounting holes for M6 screws are provided (tightening torque: 6 … 7 Nm).
Any mounting position. The system must only be operated with an angle of 2° between the solenoid interlock and the actuator.

F

The solenoid interlock can be used as an end stop. Dependant upon the door weight and the actuating speed, the mechanical life could be reduced.

Mounting of the solenoid interlock and the actuator Refer to the mounting instructions manual for the corresponding actuator.

2

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).

Actuating directions

The diagrams show a closed guard system with a set latching force of 50 N (see also chapter “adjustment of latching force”).

2

Provide for a sufficient insertion of the actuator into the rotary handle.

Correct

False

To avoid any interference inherent to this kind of system and any reduction of the switching distances, please observe the following guidelines:
The presence of metal chips in the vicinity of the solenoid interlock is liable to modify the switching distance Keep away from metal chips
Minimum distance between two solenoid interlocks as well as other systems with same frequency (125 kHz)

The minimum distance from metallic securing surfaces to the face side “A” and underside “B” of the device is 5 mm.

3.2 Manual release

For the machine set-up, the solenoid interlock can be unlocked in a de- energised condition. The solenoid interlock is

q unlocked by turning the manual release in the position

The normal locking function is only restored after the

p manual release has been returned to its original position .

Caution: do not turn beyond the end stop!

Key A: connector plug M12, 8-pole B: LED display C1: Manual release by means of slotted screwdriver

C2: Manual release by means of triangular key TK-M5
The manual release must be protected against accidental actuation, e.g. by using the enclosed seal after completing commissioning.
3.3 Emergency exit -T/-T8 or emergency release -N
With variants that have both emergency exit and emergency release, the red lever is loosely supplied. Before first use, mount the lever on the triangular part of the release using the screw supplied so that the arrow in the triangle and pin on the red lever are congruent.
The installation of the lever is possible on both sides. The opposite side can be used as a manual release by means of a triangular key TK-M5.

2

Reset of the manual release by actuating the red emergency exit lever must be prevented by the user.

2

Emergency exit (-T/-T8) (fitting and actuation only from within the hazardous area)

To activate the emergency exit, turn the red lever in the direction of the arrow to the end stop. The safety outputs switch off and the guard system can be opened. The blocked position is cancelled by turning the lever in the opposite direction. In the unlocked position, the guard system is secured against unintentional locking.

2

Emergency release (-N) Fitting and actuation only from outside the hazardous area. The emergency release should only be used in an emergency. The solenoid interlock should be installed and/or protected so that an inadvertent opening of the interlock by an emergency release can be prevented. The emergency release must be clearly labelled that it should only be used in an emergency. The label can be used that was included in the delivery.

To activate the emergency release turn the red lever in the direction of the arrow to the end stop. The safety outputs switch off and the guard system can be opened. The lever is latched and cannot be returned to its original position. To cancel the blocking condition, the central mounting screw must be loosened to such extent that the lever can be turned back into its original position. The screw must then be re-tightened.

F

To ensure correct operation of emergency exit -T/-T8 and emergency release -N, the safety door/guard must not be in a mechanically tensioned state.

2

It is possible to combine an emergency exit with an emergency release. Please note that when the red lever is actuated, the opposite lever also rotates. As such, the procedure outlined above must be followed to release the emergency release lever.

3.4 Mounting with mounting plate

4 Electrical connection

4.1 General information for electrical connection

2

The electrical connection may only be carried out by authorised personnel in a de-energised condition.

The voltage inputs A1, X1, X2 and IN must have a protection against permanent overvoltage. Supply units according to EN 60204-1 is recommended.
The required electrical cable fuse protection must be integrated in the installation.
The safety outputs can be integrated into the safety circuit of the control system.

Requirements for the connected safety-monitoring module: Dual-channel safety input, suitable for 2 p-type semi-conductor outputs

F

Configuration of the safety-monitoring module If the safety sensor is connected to electronic safety-monitoring modules, we recommend that you set a discrepancy time of min. 100 ms. The safety inputs of the safety-monitoring module must be able blanking 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.

F

Information for the selection of suitable safety-monitoring modules can be found in the Schmersal catalogues or in the online catalogue on the Internet: products.schmersal.com.

4.2 Serial diagnostic -SD
Cable design The wiring capacity of the connecting cable of the solenoid interlock must not exceed 50 nF. Depending on the strand structure, normal unshielded 30 m long control cables LIYY 0.25 mm² to 1.5 mm² have a wiring capacitance of approx. 3 … 7 nF.

F

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

F

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.

4.3 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 AZM300 … 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.

5 Actuator coding and latching force adjustment
5.1 Actuator coding
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.
5.2 Latching force adjustment
In order to enable trouble-free functionality of the device, the rotary handle must be in position I or II when the safety guard is open. In the intermediate positions, locking is impossible. The latching force is changed by turning the rotary handle by 180°. In position I,the latching force is approx. 25 N. In position II, the latching force is approx. 50 N.
6 Active principle and diagnostic functions
6.1 Magnet control
In the power to unlock version of the AZM300, the solenoid interlock is unlocked when the IN signal (= 24V) is set. In the power to lock version of the AZM300, 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 AZM300Z 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 AZM300Z solenoid interlock; in that case, the safety outputs are re-enabled. It is not necessary to open the safety guard. In the AZM300B version, only the opening of the safety guard causes the safety outputs to be disabled.
6.3 Diagnostic-LEDs

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 be disabled within the duration of risk. After fault rectification, the error message is reset by opening and re-closing the corresponding safety guard.
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 serieswiring 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.
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).
Diagnostic error (warning) If an error (warning) is signalled in the response byte, detailed fault information can be read out.

1. The leading diagnosis message through bit 1 indicates whether locking or unlocking of the guard system is possible. The solenoid interlock cannot be unlocked if e.g. the door pulls the turret out of its rest position beyond the set latching force. This can occur if doors are heavily distorted or when pulling the door. The solenoid interlock can only be locked if the turret is in the rest position, i.e. the latching force is sufficient to pull the guard system into the correct position. 2) after 30 min -> fault

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. Check max. angular misalignment (see “Mounting” part). 4. Fitting and integrity of the cable connections. 5. Check the switch enclosure for damages. 6. Remove particles of dust and soiling. 7. For versions with emergency exit and emergency release the following should also be considered:
– For versions with emergency exit it must be possible to open the guard system from within the hazardous area; it must not be possible that the guard system is blocked from the inside. – By operating the emergency release lever outside of the hazardous zone it must be possible to open the guard system.

2

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.

2

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.
