- Safety Engineering


The subject of safety engineering for protection ofman, machine and product is increasing in impor-tance all the time. Consequently, precautions haveto be taken to protect operating personnel workingon industrial machines and installations in order toavoid both injury and damage. Above all, this meansrecognizing areas with dangerous movements orconditions and protecting them.

In addition, safety switches can be used on ma-chines and installations to ensure that they arestopped if predefined mechanical limit values areexceeded.

If a potential source of danger cannot be eliminatedor adequately reduced by design measures, thenecessary degree of protection must be achieved byuse of movable safety guards.

The following functional demands must be satisfied :

� Positive action of the safety guard at the start ofor during the dangerous condition.

� Positive deactivation of the dangerous conditionif the safety guard is removed.

� Locking of the safety guard until the dangerouscondition has ended, e.g. due to machine rundown movements after machine shut down.

� Every safety function must be resistant to ma-nipulation and must not be easily defeated.

The demands which have to be satisfied by an indi-vidual safety guard are determined by means of arisk assessment. This analysis acts as a basis forgraded monitoring and signal processing solutionscorresponding to the degree of danger involved.Possible realization methods extend from simple,mechanical-action safety position switches to self-monitored locking with start-up testing.

With a perfected designed and fully-developed rangeof safety components, EUCHNER can help you tosolve your safety problems.

Safety switch categories

Safety switches are divided into two different cate-gories.

Switch Category 1

Switches where the switching element and actuatorform a unit.

Switch Category 2

Switches where the switching element and actuatordo not form a design unit, but are functionally com-bined or separated during actuation.(See page 10 for other designs).

Automatic mode

Automatic mode is an operating mode where, incontrast to manual mode, only system start-up isinitiated by human intervention. All further se-quences are executed automatically.

Dangerous conditions

These conditions which may lead to injuries. Safetyswitches eliminate this risk in conjunction with properuse of the safety guard.

Manipulation

Manipulation is the intended deactivation or defeat-ing of safety guards and their components.

Safety switches and guards must be designed sothat the safety functions cannot be changed or by-passed by hand or by using a simple tool. Simpletools include screwdrivers, ballpoint pens, nails,pieces of wire, adhesive tape, etc.

Simple tools do not include items which have to beproduced using tools in more than one operation.

Dismantling of parts, turning the safety switch fromits protective position, use of a second actuator orbridging of contacts do not fall into the category ofbypassing in a simple manner.

Wilfull and intended deactivation of safety guards isalways treated as a grossly negligent act with corre-sponding consequences in the event of accidents.At the design stage, it should be remembered thatsimple and proper operation of machines and instal-lation must remain possible in spite of the safetyguards. If this fact is forgotten, this may lead tosafety measures being bypassed.

Installation

The mounting location and installation method ofsafety switches are decisive criteria in ensuring reli-able monitoring of safety guards and their function-ing with respect to general operating safety.

Safety guards and their components such as safetyswitches must be viewed in direct relation to theirpossible manipulation. Design precautions shouldtherefore be taken to practically eliminate thesepossibilities.Equally important to observance of general rules andregulations, e.g. form-fit assembly of all safety com-ponents in safety guards, a further reduction in riskcan also be achieved by implementation of preven-tive design measures.

� Mounting of safety switches behind the safetyguards or inside the installation.

� Locking out of the actuator entry opening of thesafety switch (category 2) when the safety guardis open (see lockout bar, page 106).

� Assembly location of the switch actuator in a so-called C-rail to prevent the use of a „second“actuator.

Standards

Certain regulations, standards, directives and rec-ommendations must be observed when designingsafety devices and their components.

A list of the most important standards can be foundon Appendix A II.

Definition of Terms

Manipulation protection by means of a C-rail


Risk analysis

It is necessary to carry out a risk analysis in order todetermine the safety objectives and the corres-ponding measures required. The required safetysolutions are defined by taking into account the riskparameters and the degree of danger.(See Appendix AI for further information).

Switching elements

The switching elements of safety switches mustpossess positive actuators. The switching elementsfor the safety function must be positively driven or, incase of snap-action switching elements, guaranteereliable opening of the NC contact when the positiveopening point is reached.

A distinction is made between the following switch-ing element types corresponding to their switchingbehaviour :

� Slow-action contact elementContact element which opens or closes dependent on the speed of its actuation.

��Snap-action contact elementContact element which opens or closesindependently of the speed of its actuation.(See page 8 and 9 for further information).

Safety guards

A basic distinction is made between fixed andmovable safety guards. Fixed safety guards areused at dangerous locations where it is notnecessary to intervene or where intervention isnecessary only on rare occasions. These guards arenormally permanent and can be removed only bymeans of tools. Movable safety guards are usedwherever it is necessary to reach into the dangerouslocation for the purpose of machine operation, faultrectification or during set-up mode. These guardsare monitored by means of safety switches.

Safety switches

Safety switches are safety devices which are used tomonitor movable safety guards. They must reliablyinterrupt the circuit when the guard in question isopened and keep the circuit open until the guard isclosed again. Safety switches with solenoid interlockare locking devices which act in conjunction with thecontrol to keep movable safety guards in their safetyposition until dangerous conditions no longer exist.

Cycle operation

This involves manual intervention at dangerouslocations during the working cycle of the machine.Here, the safety measures must guarantee a highsafety level in monitoring of the safety guard and insignal processing. If these conditions are satisfied,the start command can be issued in this mode afterproper return of the safety guard to its protectiveposition.

Enabling switches

These are manually-operated control devices whichare designed for working in the danger areas ofmachines and installations.The protective effect of movable safety guards isdeactivated under certain conditions when workingin „Manual“ mode. Authorized personnel can enterdanger zones with the enabling switch to performprogramming set-up, observation, repair, test orservice work.(For further information, refer to page 110, Chapter„Enabling switches).

Positive opening

Positive opening for safety switches means thatthere must be positive force transmission betweenthe actuator and switching element.The actuation mechanism must be designed so thatthe contact point opens reliably and remains open inactivated condition even in the event of mechanicalfailure, e.g. breakage of a spring or contact welding.Further regulations are defined in the standard IEC947-5-1, EN 60947, VDE 0660, part 200.

EUCHNER Safety Switches marked with this symbolindicate N/C switches with positively driven contacts.This also meets the requirements of IEC 947-5-1.

- Safety Switches


Application

The safety switches in this series are used forprotection of personnel, machines and productiongoods throughout the whole field of mechanical andplant engineering thanks to their design concept andhigh degree of flexibility.

A fully-developed design, the use of top qualitymaterials and EUCHNER-production know-howguarantee problem-free operation of these devicesunder even the most stringent conditions.

Two different types are available :

Position switches in accordance with EN50041 with safety function

Type series NZ

Precision single limit switches inaccordance with DIN 43693 with safetyfunction

Type series N1A

Design

The safety switches of this series possess ananodized die-cast light alloy housing. They arecharacterized by a high level of operating reliability,high strength and corrosion resistance.

Reliability and function are assured over and beyondthe guaranteed service life by the use of top qualitymaterials for the plungers, drive mechanisms andseals.

Function

This series is characterized by positive interaction ofall actuating elements in the functional sequence ofthe switches. This guarantees that the switchingelement responsible for the safety function positivelydisconnects circuits even in the event of contactwelding, for example.

Convertibility

These safety switches are universal components forthe whole field of mechanical and plant engineeringthanks to the many conversion possibilities :

� approach directions (4 x 90°)� actuator directions (4 x 90°) for roller-lever

mechanism� switching directions left/right/two-way.

Safety Switches Category 2

Switches where the contact element and actuator do not form a designunit, but are functionally combined or separated upon actuation.

- Safety Switches


Design

The housings of these safety switches are made ofanodized die-cast light alloy. The high degree ofprotection IP 67 permits these devices to be usedunder extreme conditions and protects them reliablyagainst ingress of dirt and coolant.

EUCHNER offers three different series correspond-ing to the various operating criteria :

� without solenoid interlock

� with solenoid interlock, without lockingmonitoring for process safety(not for personnel safety)

� with solenoid interlock andinterlock monitoring

All safety switches possess an actuator head designwhich has proven itself 100,000 times in practicaluse. The actuator head can be adjusted in four di-rections.

Function

EUCHNER safety switches can be switched only bymeans of an actuator with multiple coding which isspecifically intended for the switch in question. Thisactuator initiates an exactly predefined function se-quence in the switch, thus practially excluding thepossibility of unintentional actuation or manipulation.When the actuator is removed or the safety guardopened, the safety switching element is reliably ope-ned, by positive force transmission, e.g. also in theevent of welded contacts, and is then locked in ope-ned condition. Safety switches of the series TZ pos-sess an additional element which is actuated by thelocking device as well as the element which is direct-ly switched by the actuator. The unambiguous signal„Safety guard closed and locked“ can be sent to thecontrol system by wiring the two switching elementsin series.

Actuator

The actuator possesses multiple coding and compri-ses a laminated spring steel core coated with abra-sion-resistant plastic. This combination guaranteesmaximum operating reliability combined with mini-mum wear of the safety switch.

The following are available for the various possibleapplications :

� 2 straight actuator (e.g. sliding covers)� 4 hinged actuators (e.g. doors, flaps)

Mechanical unlocking mechanism

EUCHNER-safety switches of the series TZ.. pos-sess an mechanical unlocking mechanism whichallows the safety guard to be opened in the event ofa power failure, for instance, irrespective of the posi-tion of the locking solenoid. Intentional unlocking ormanipulation is possible only by destroying the leadseal provided.

Lead seal set

Safety switches of the type range TZ with PG-entryare delivered without the seal fitted. A lead seal setis delivered with every switch.

Safety switches of the type range TZ with connec-tor are delivered where the mechanical unlockingmechanism seal is fitted. An additional lead seal setis packed with each switch.

Locking methods

The EUCHNER safety switches of the Category 2are available with two different locking methods.

� Mechanical locking (spring force)

Locking takes place here immediately after in-sertion of the actuator or closing of the safetyguard. Unlocking is possible only by applying theoperating voltage to the solenoid or, in the eventof power failure, by means of the auxiliary un-locking mechanism (see above) (closed circuitprinciple).

� Electrical locking

Locking takes place by applying the operatingvoltage to the locking solenoid, and unlocking byremoving the operating voltage (open circuitprinciple).This type must be used only in special casesafter strict assessment of the accident risk!The protective guard can be opened immedi-ately in the event of interruption of the solenoidpower supply.

Manipulation protection

Optimum manipulation protection can be realized byadditionally mounting a protective bracket on the topside of the actuator head. This prevents interventionin the safety switch from the exit opening of the ac-tuator.This option is simple and quick to install.(See page 107 for Accessories).

Actuators - Bolts - Accessories

for Safety Switches

- Safety Switches


EUCHNER category 2 safety switches can be opera-ted only with an actuator which is specifically inten-ded for the switch in question. This actuator initiatesan exactly defined functional sequence in the safetyswitch. This guarantees optimum protection againstunintentional actuation and manipulation.

The actuators must be fitted on their mounting sur-face by means of a positive connection in accordan-ce with the applicable regulations (e.g. VDI 2854),i.e. they must be welded, riveted or otherwise secu-red to prevent them from being detached.The actuator and safety switch must be assembledtogether for installation in order to ensure reliableoperation.

The actuator comprises a laminated spring steelcore coated with abrasion-resistant plastic to guaran-tee maximum reliability combined with minimumwear.Two straight actuator and four hinged actuatorsare available to meet the needs of an extremely widevariety of applications.

Actuators must not be used as guides or end stopsin conjunction with safety switches. Safety guardbolts must be used if this task cannot be solved bydesign measures.EUCHNER safety guard bolts are available for allsafety switches of the type series NZ.. and TZ... (seeAccessories on pages 92-95).

Safety screws see Accessories,page 99.

Cable glands

The following table contains the cable glands suitable for the corresponding internal thread in the EUCHNERsafety switch and for the outer diameter of the cable used.

Lockout bar

The locking insert can be inserted in the safety switch instead of the actuator when the safety guard is in opencondition and can then be secured to prevent removal by standard commercially available padlocks (max. 3 pcs.).This guarantees reliable protection for persons who have to enter potentially hazardous areas.

- Enabling Switches


General

Enabling switches are manually operated control devi-ces which are intended for use by persons working indanger areas of machines and installations.In „Manual mode“, the protective effect of movablesafety guards may be disabled under certain conditi-ons.Authorized personnel can then enter dangerousareas with the enabling switch, subject to observan-ce of certain preconditions, in order to perform pro-gramming, set-up work, testing or service work, forexample.Enabling switches can perform their task properlyonly if safe handling is possible for long periods, e.g.during observation of production sequences, withoutthe operator becoming tired.Besides an absolute safe function we put specificattention to a perfect and balanced ergonomics ofthe EUCHNER enabling switches, in order to beingable offering a product which can be operatedpleasantly in order to reduce readiness for manipu-lation.

Design

All EUCHNER enabling switches have a robustplastic housing offering a high degree of protection.The fully-developed design is characterized by thefollowing features:

�� perfect ergonomics�� light weight�� easily switched from hand to hand�� light and stable action point�� redundant make circuits�� reliable line monitoring for cross shorts�� tamper resistant

EUCHNER enabling switches are available in

�� different hand versions and�� different built-in versions

each with different switching element configurationsin each case.The hand versions are available with three differentcable types, namely 5 m or 10 m straight cable or 5m coiled cable, and also as a kit.The patented cables of the enabling switches pos-sess individually shielded conductors to permit ef-fective cross-short monitoring. The shields must beconnected with the PE system of the machine orinstallation.If the cables are then crushed, for example, shortcircuits will be detected and the control switched offimmediately by tripping of the short-circuit protectivedevice. This eliminates the need for an additionalevaluation device for line monitoring.

Function

The functional sequence of EUCHNER enabling swit-ches meets the requirements for 2-stage and3-stage enabling switches in accordance with EN 775and VDI 2854.

Functional sequence of 3-stage enabling switches:

Stage 1: OFF function (actuating element not pressed)

Stage 2: Enabling function (actuating elementpressed to center position)

Stage 3: OFF function with positive opening operation (actuating element pressed down fully past the center position)

A patented switch mechanism prevents the enablingfunction from being activated when the switch re-turns from stage 3 to stage 1.The exact functional sequence is shown in the swit-ching diagrams of the respective enabling switches.

Application

Enabling switches are used in automated productioninstallations, for example, which are operated in„Manual mode“ in accordance with the regulationEN775 and VDI 2854. This operating mode must bedefined by means of lockable selector switches asstipulated in EN 60204 T1 (DIN VDE 0113 T1).Safety guards are partially disabled in this mode. Forthis reason, the person working in the dangerousarea with the enabling switch must be able to reco-gnize dangerous conditions in good time and initiatecorresponding counter-measures.

Important:

Commands for dangerous operations must not beinitiated with the enabling switch alone. A „second,conscious“ start instruction is necessary for this pur-pose. Each person to be in the dangerous area hasto have an own Enabling Switch.

Approvals

EUCHNER enabling switches have the followingapprovals:

BIA, GermanySUVA, SwitzerlandSAQ, Swedenas well as approval by the automotive industry(see Appendix A III for further details).

Risk analysis

Control Categories

Safety consideration for safety guards

Monitoring of movable safety guards includes the devices for position monitoring and for signal processing in thecontrol system.Signal processing of the safety circuits must be integrated in the overall control system so that this cannot berendered ineffective by other control elements.

Safety circuits may carry out an operational function, but must primarily perform safety tasks and be able todirectly intervene in load circuits where there is potential danger.

Safety guards and their monitoring and signal processing systems have to satisfy variously high requirements,depending on the degree of potential danger to persons and machines. Possible realization forms extend from asimple mechanical-action position switch to a self-monitoring locking mechanism with start-up testing. The requi-rement level which should be satisfied in an individual case can be determined in a risk analysis that takes intoaccount the danger parameters.

Risk estimation according to EN 954-1

The method described in this standard permits therisk involved in a particular application to be estima-ted on the basis of a few parameters which are cha-racteristic for the risk.

This risk analysis allows determination of a so-calledrequirement class from a predefined classificationscheme.

S - Severity of injury

S1 - Slight (normally reversible) injuryS2 - Serious (normally irreversible) injury including death

F - Frequency and/or exposure time to the hazard

F1 - Seldom to quite often and/or the exposure time is shortF2 - Frequent to continuous and/or the exposure time is long

P - Possibility of avoiding the hazard

P1 - Possible under specific conditionsP2 - Scarcely possible
