This brochure contains a short overview of the indi-vidual product lines and the main accessories avail-able within the Schmersal Group for guard locking applications.

The technical data for the individual devices are complemented by wiring diagrams, which show how simply Schmersal components can be wired together into a complete system.

In addition, solenoid inter-locks can also help meet the safety requirements defined in EN 1037, i.e. the protection against unexpected start-up of machinery.

The Schmersal Group of-fers its customers the largest program of safety control systems for the protection of man and ma-chine, in particular a large range of solenoid inter-locks and intelligent ac-cessories that facilitate the integration of solenoid in-terlocks into the user’s ap-plication.

The program includes door handle switches, mounting sets and a large range of actuators, suitable even for small actuating radii. Together with fail-safe standstill monitors and safety control modules, complete system solutions can be configured. Most machine guarding

on industrial machinery is fitted with guard-locking safety interlocks (solenoid interlocks). This has two reasons:

Firstly, EN 1088 requires that hazardous areas on machinery and plant re-main inaccessible until all dangerous machine move-ments have stopped. This can be achieved by in-stalling a solenoid interlock on movable machine safe-ty guards.

Secondly, solenoid inter-locks also serve to safe-guard the process: any unauthorised intervention in the running processes or any unexpected ma-chine stop by an unfore-seen opening of a safety guard is avoided. For ex-ample, a solenoid interlock can ensure that a robot completes its entire cycle before it stops. Moreover, solenoid interlocks can prevent damage to a ma-chine tool through an un-expected stop, thus help-ing to ensure maximum productivity.

5 Installation and operating solenoid interlocks

Fig. 1: Solenoid interlock AZM 170 with separate actuator

The Schmersal guard-locking safety interlocks are based on the principle of the “separate actuator” (Fig. 1):

The actuating element (the actuator or “key”) is fitted to the movable part of the machine guard (usually a safety guard). The solenoid interlock itself is mounted to the stationary part of the guard, for example the door post. The machine can only start when the actuator (mounted on the moveable guard) has en-tered the solenoid interlock and is locked in position.

To optimise the benefits of this principle, some basic rules for the design of the machine guard and inter-lock mounting, as well as during machine operation, must be observed. The following pages contain practical hints and advice on mounting and operat-ing solenoid interlocks.

(6)

Fig. 3: Positioning of the solenoid interlock and door handle on a safety guard

Fig. 2: Door handle switch TG with AZM 190

Solenoid interlocks should be fitted near the door handle

For trouble-free guard locking, it is imperative that the actuator smoothly enters the solenoid inter-lock throughout the guard´s intended lifetime. To achieve this, the safety guard must have a degree of stability that does not allow torsion or door-setting.

In addition, it is recom-mended to fit the safety guard handle as close as possible to the solenoid in-terlock. This ensures that the actuator can always be easily extracted or inserted into the solenoid interlock, even in case of a de-formed or distorted safety guard (see Fig. 3).

(7)

Fig. 5: Fixed and flexible actuator End stop – for heavy

safety guards fit a damper against rebound

The solenoid interlock must not be used as me-chanical end stop or as a guide for the safety guard. A separate end stop is re-quired. Even with an end stop, the rebound from a heavy safety guard can lead to serious damage to the solenoid interlock and/ or actuator if, upon closing the door, the solenoid latches the actuator into the locked position. To prevent this, a damper can be fitted to the door.

All in one:

door handle switch TG

For larger machines and assembly lines which have many safety guards, a separate unlocking button should be fitted near or on each safety guard to enable individual guard unlocking. In this way, the operator does not need to go to the machine control panel and unlock all safety guards; but can unlock and lock only the safety guard re-quired.

The door handle switch TG developed by the Schmersal Group features a door lock control button with integrated LEDs to in-dicate if the safety guard is locked or released. This ergonomic aspect helps deter the operator from prematurely pulling on the door and jamming the un-locking mechanism. An emergency stop button can also be integrated into the door handle switch where required (Fig. 2).

Actuator: fixed or flexible?

The size of a hinged guard can limit the operating ra-dius of the actuator. To guarantee smooth inser-tion of the actuator into the solenoid interlock in such cases, the Schmersal Group offers a large range of actuators specially de-signed for small actuating radii. On hinged guards the use of flexible ad-justable actuators is rec-ommended; for sliding guards, fixed actuators are more suitable (Fig. 5).

We recommend attaching the actuator inextricably to the safety guard, for exam-ple using one-way screws to avoid the actuator being removed for unauthorised use. As an alternative the actuator can be fitted in a concealed position, which also minimises the risk of injury from the actuator (Fig. 4).

(8)

Fig. 7: Power to lock Operating principle:

spring to lock or power to lock?

All solenoid interlocks de-veloped by the Schmersal Group feature a fail-safe locking mechanism. This design feature, described in EN 1088, means that the solenoid locking bolt can only lock after the ac-tuator has entered the in-terlock i.e. the safety guard is closed. This means that the safety cir-cuit can be enabled using the solenoid contacts only. The actuator contacts are used solely for position in-dication of the safety guard.

Since solenoid interlocks featuring a fail-safe locking mechanism offer a higher degree of safety, the in-stallation of a second de-vice for monitoring safety guard position can be left out under certain circum-stances (see page 28).

Solenoid interlocks have two different operating principles:

• Solenoid interlocks with spring to lock are locked by spring force and un-locked by energising the solenoid (Fig. 6). • Solenoid interlocks with

power to lock are locked by energising the sole-noid and unlocked by spring force (Fig. 7).

Both principles are com-mon on machine safety guards. For the protection of personnel against haz-ardous stored energy (e.g. run-on), the use of sole-noid interlocks with spring to lock is strongly recom-mended.

Solenoid interlocks with power to lock may only be used in special cases after evaluating fully all the haz-ards, since in case of power failure or machine power switch off, the guard can be opened im-mediately and the operator exposed to the hazard.

On the other hand, solenoid interlocks with power to lock are suitable for ma-chine and/or process safety.

This type of solenoid inter-lock can deter the opera-tor from interrupting a run-ning process and, for ex-ample, avoiding damage to machine tools. The power to lock princi-ple enables fast access into the machine in case of failure – when the machine power is switched off the safety guard can be un-locked. Using a solenoid interlock in this way can help optimise the machine productivity.

Fig. 8: Mounting kits simplify the fitting of solenoid interlocks Fig. 9: Simple but effective mounting of the AZM 190 due to its special housing design

Mounting sets simplify fitted

Schmersal has developed mounting sets to enable quick and safe fitting of solenoid interlocks and ac-tuators. The mounting sets are suitable for fitting on common steel and alumini-um profile systems and simplify the alignment be-tween actuator and sole-noid interlock (Fig. 8).

The unique housing design of the AZM 190 allows a particularly elegant solution for hinged guards and alu-minium profile systems. The angled actuating head allows the solenoid inter-lock to be mounted inside the hazardous area so that only the head is visible from outside. In addition to the practical advantages, this device can also im-prove the optical impres-sion of the machine – an important factor on mod-ern machines (Fig. 9).

Caution: Pre-tensioned safety guards!

In spite of careful safety guard design, the practice shows that they often be-come deformed, distorted or misaligned during their lifetime. With this in mind, a certain play between the actuator and the solenoid interlock is tolerated by de-sign, so that the safety guard can be displaced from its ideal position.

Safety guards are also pre-tensioned by operators try-ing to open a locked door. This force must not exceed a specific maximum pre-tension force for the sole-noid interlock concerned, otherwise the solenoid will not be able to unlock, and

the door cannot be opened. Schmersal’s patented tog-gle-lever system can with-stand a maximum admissi-ble pre-tension of up to 500 N (AZM 415).

In addition, a specific hold-ing force (the so-called latching force) is present, so that the tensioned guard is held closed even in an unlocked condition.

When selecting the appro-priate solenoid interlock, the maximum permissible holding force on the device in the locked position must be taken into account. Schmersal solenoid inter-locks are available with a holding force of between 1000 N and 3500 N.

(10)

Since solenoid interlocks are either locked or un-locked by a solenoid, they require differing solutions for manual unlocking in a power-off condition (for example during installation or maintenance) than for unlocking during machine operation.

Battery-operated release*

When spring to lock sole-noid interlocks are in-stalled in inaccessible or concealed positions, and in the case of power off or failure, the operator is con-fronted with the problem of how he gains access to the machine. In this case, it is useful to provide a separate power supply for the solenoid. This can be a battery-operated release in the control cabinet. The battery is charged during normal operation and in the case of power failure, can be switched on to un-lock the safety guard.

* In preparation

Fig. 11: B30 actuator with integrated emergency handle Fig. 10: Manual release

Manual release

Machinery fitted with spring to lock solenoid in-terlocks normally have a way of opening the safety guard during a power fail-ure, usually by means of a tool such as a triangular key (Fig. 10). The Schmer-sal solenoid interlocks are fitted with such an auxiliary unlocking mechanism, the so-called “manual re-lease”.

Upon operating the manu-al release, the positive break safety contacts are simultaneously opened thus preventing unexpect-ed machine restart.

(11)

Fig. 14: Solenoid interlock with integrated fail-safe standstill monitor

Fig. 13: Emergency exit or emergency release Emergency release

With an emergency re-lease, the safety guard can be opened from outside the hazardous area with-out the operator using any tool, for example when a fast intervention into the hazardous area is required to guarantee process safe-ty. Unlocking is possible without special tools, re-setting however requires a repair-like intervention.

times – fail-safe delay timers. For these applica-tions, the Schmersal Group has developed a compre-hensive range of fail-safe standstill monitors (Fig. 14). For these types of ma-chine an emergency stop safety control module with delay on de-energisation (stop category 1 to EN 60204-1) must not be used, since the failure mode of the delay function is t = 0. This would result in the safety guard unlock-ing too soon in case of failure.

Standstill monitoring

Solenoid interlocks for personnel protection are used when the time taken to access the hazardous area from the safety guard can be less than the time needed for the hazard to have ceased (i.e. the mov-ing parts have come to a standstill). The safety guard must remain locked until the machine hazard has been reduced to a minimum. In this case, the solenoid interlock can be combined with a fail-safe standstill monitor or – in case of constant run-down

Emergency exit

The emergency exit allows an intentional opening of the safety guard from in-side the machine without tools, for example when personnel are trapped in-side a machine (Fig. 12 and 13).

For this application, the Schmersal Group has de-veloped the AZM 415 and TZFS.NN with emergency release which, used to-gether with a B30 actuator and integrated emergency handle, allow an emer-gency exit from inside a machine guard (Fig. 11).

Fig. 12: Emergency exit

(12)

Fig. 14: AZM 415 with B30 actuator

This allows personnel to evacuate the hazardous area easily. By operating the emergency release, the safety circuit of the machine is interrupted and the machine is shut down.

However, in order not to endanger personnel that could be inside the haz-ardous area during the start-up or restart, the fol-lowing aspects have to be taken into account. Hazardous areas of

ma-chinery and plant can be so large, that the machine can be entered completely by personnel.

The Machinery Directive requires that in this case personnel cannot be inad-vertently locked into the hazardous area.

To prevent this situation, solenoid interlocks can be fitted with the emergency exit system described previously.

Fig. 15: Full body access of hazardous areas

(13)

First of all, the start button must be installed in a loca-tion where the operator has a complete overview of the hazardous area. In addition the start button must not be accessible from inside the hazardous area.

Secondly it is strongly rec-ommended to use a safety control module with a monitored start circuit.

y access

These safety control mod-ules enable only a trailing edge signal from the start button, i.e. they enable when the button is re-leased, not when it is pressed. The trailing edge control module can thus detect a failure in the start button (e.g. contact weld-ing) and manipulation (but-ton held down).

The comprehensive range of safety control modules from the Schmersal Group include monitored start (trailing edge) function.

General notes

The following wiring diagrams are very practice-oriented, and outline only a few examples of how solenoid interlocks can be integrated into the machine safety control system for various applications.

In order to obtain the indicated control categories to EN 954-1, the following points should be observed:

1. The specific safety regulations contained in the prevailing C-standards describe how solenoid interlocks should be in-tegrated into the safety circuit of a machine. If the manufac-turer fulfils these requirements, he simultaneously complies with the relevant essential requirements of the Machinery Di-rective by reason of the so-called presumption of conformity.

The manufacturer may deviate from the C-standard, but in that case, he must show that his machine is designed in such a way that through equivalent measures, it conforms to the essential safety requirements laid down in the Directive.

If no C-standard is available for the specific application, the B-standards must be consulted for information regarding the use of solenoid interlocks.

2. Second safety guard switch:

The second safety guard switch can serve for fault recogni-tion and fault control if the solenoid interlock incurs a critical failure, such as undetectable damage to the internal or ex-ternal mechanism.

The installation of a second safety guard switch can be omitted:

• In case of thorough and proper safety guard design, i.e. a stable door mechanism with solid end stops, designed to operate correctly throughout the planned lifetime of the machine,

• If the maximum admissible holding force and other mechanical limits of the solenoid interlock are observed, • If the actuator is inextricably attached to the safety guard

(see page 7), preferably in a concealed position,

• If the actuator blade is manufactured in one piece and not made of plastic or die-cast material,

• If the solenoid interlock contains a fail-safe locking mechanism.

However, we always recommend the use of a second safety guard switch:

• for applications to control category 4 to EN 954-1, • for non-visible hazards such as radiation, electric shock, etc.

3. For applications where the higher safety requirements must be met, the following should be observed:

• for applications in control category 4, the possible accu-mulation of faults must also be considered. To detect mul-tiple faults all safety guards fitted with electromechanical devices must also be equipped with a start-up test. i.e. where solenoid interlocks are used, the safety guard must be opened and closed after powering up the machine. This ensures the detection of hidden faults that were erased due to the supply voltage being switched off.

• for applications in control category 3 some faults are not always continuously recognised if the solenoid interlocks are connected in series. An accumulation of faults in one solenoid interlock could in this case lead to the loss of the safety function for a particular safety guard. For example, the recognition of a fault in a solenoid interlock circuit caused by short-circuit or cable breakage can be cancelled out by actuating another solenoid interlock. This fact must be considered in the risk analysis.

• if the possibility of short-circuit or cross-wire faults cannot be excluded by special cable routing, the use of safety con-trol modules with cross-wire detection is recommended.

The ultimate classification of a safety control circuit in a control category to EN 954-1 can only be defined for a specific appli-cation once all aspects of the system have been evaluated. For this reason, the control categories proposed in the following wiring diagrams apply solely to the input circuit and do not con-sider the safety control module or any other part of the safety control circuit.
