European directives

The concept of a single European internalmarket in terms of the "New Approach" canbe traced right back to the start of the 70s:The low voltage directive was the first pieceof European legislation to take into accountthe approach towards harmonisation of acommon internal market.

Products that are covered by one or more ofthe following directives have to apply a CE-mark, i.e. the product must be accompanied

by a declaration of conformity. With adeclaration of conformity the manufacturerconfirms that his product meets all therequirements of the European directives thatrelate to his product. This means he canlaunch and sell his product within the scopeof the EU without consideration of anynational regulations.

ATEX 94/9/ECAppliances burninggaseous fuels 90/396/EECMachinery directive 98/37/ECMedical device directive 93/42/EECLow voltage directive 73/23/EECPersonal protective equipment 89/686/EECSafety of toys directive 88/378/EEC

The directives are addressed to memberstates, who are obliged to incorporate theEuropean directives into domestic law. InGermany this is normally achieved throughthe device safety law.

Position of the standards in Europe

The legal position of standards is discussedagain and again. Inside Europe, i.e. withinthe scope of the European directives thatare subject to the CE-marking obligation, amanufacturer is not bound by standards orother specifications. He simply needs tocomply with the health and safetyrequirements of the directive(s). Theassociated benefits of a division betweenstandards and legislation are obvious: It iseasier for legislators to agree on the essenti-al requirements than on technical details.Also, the directives do not regularly have tobe adapted to the state of technology;member states can use their own legalsystem for incorporation and manufacturersare free to select the ways in which theyimplement the requirements of the directive.

So what are the benefits of applying thestandards? With so-called harmonisedstandards with presumption of conformity,there is a shifting of the burden of proof, i.e.if manufacturers apply these standards, it ispresumed that they will also comply with thespecific requirements of the Europeandirectives.

The regulatory authorities would thereforeneed to prove that a manufacturer did notmeet the legal requirements.

However, should a manufacturer deviatefrom the harmonised standards, he himselfmust prove how he has met the essentialsafety requirements. This is generally donevia a hazard analysis. In practice one wouldendeavour to apply the harmonisedstandards, unless the products concernedare highly innovative and no harmonisedstandards yet exist. The standards for whichthis "presumption effect" applies can beresearched in the Official Journal of the EU

(e.g. on the Internet). Standards in Europeare subdivided into what are termed A, B,and C standards.

Legal regulations outside Europe

The situation is somewhat different in theUSA: people there are mainly familiar withtwo types of standards: ANSI (AmericanNational Standards Institute) and OSHA(Occupational Safety and Health Administra-tion).OSHA standards are published by the stateand compliance is mandatory. ANSIstandards, on the other hand, are developed

by private organisations and theirapplication is generally not absolutelyessential. However, ANSI standards can stillbe found included as part of a contract.Beyond that ANSI standards are being takenover by OSHA. You can still come acrossthe NFPA (National Fire ProtectionAssociation), which developed NFPA 79 asa counterpart to EN 60204-1, for example.The OSHA standards can be compared withthe European direct-ives. Unlike the European directives, theOSHA standards are more involved withformulating technical specifications thanabstract requirements.

The legal basis in the USA can be seen as amix of product standards, fire codes (NFPA),electrical codes (NEC) and national laws.Local government bodies have the authorityto monitor that these codes are beingenforced and implemented.

Russia and the CIS states haveimplemented GOST-R certification for someyears now, in other words, technical devicesthat fall within a specific product area mustundergo a certain certification process.Machinery and any corresponding technicalaccessories undergo a type approval testthrough a European notified body, for ex-ample. This test is generally recognised by aRussian-based approvals body. From thepoint of view of safety, the samerequirements apply as in Europe.

China, on the other hand, has introducedCCC certification. Similar to the position inRussia, technical products are subject tomandatory certification through a nationalapprovals body in China. In addition,production sites are inspected. If a technicaldevice falls with the scope of the productlist, which is subdivided into 19 categories,certification is mandatory, otherwise it willbe necessary to supply a type of"declaration of no objection" from a nationalnotified body.

Japan is currently in a transition period: Theplan is for Japan to adopt the European"new approach" – in other words, to keepstandards and legislation separate. At themoment the international ISO and IECstandards are being directly incorporatedinto national legislation, which is why peopleare currently confronted with frequentamendments to laws and lengthyimplementation periods.

Standards for functional safety

Different standards may be called upon toobserve functional safety on controlsystems, depending on the application. Inthe area of machine safety, EN 954-1 is themain standard named for safety-relatedcontrol systems. Irrespective of thetechnology, this applies for the whole chainfrom the sensor to the actuator. The riskgraphs and corresponding risk parameterscan be used to estimate the potential riskfor danger zones on machinery. Thecategory is then established without the useof risk-reducing measures.

Risk parameters

S = Severity of injury:1 = Slight (normally reversible) injury2 = Serious (normally irreversible) injury,including death

F = Frequency and/or exposure to thehazard1 = Seldom to quite often and/or exposuretime is short2 = Frequent to continuous and/or exposuretime is long

P = Possibility of avoiding the hazard1 = Possible under specific conditions2 = Scarcely possible

Categories in accordance withEN 954-1

The control system requirements derivedfrom the risk graph are specified as follows:

Category B

Basic category with no special requirements= "good industrial standard"

Category 1

Safety-related parts must be designed andconstructed using well-tried componentsand well-tried safety principles.

Well-tried means: the components havebeen widely used in the past withsuccessful results in similar applications, orthey have been manufactured usingprinciples that demonstrate its suitabilityand reliability for safety-related applications.

Example: safety switch with forced-openingcontacts.

Well-tried safety principles are circuits thatare constructed in such a way that certainfaults can be avoided by the appropriatearrangement or layout of components.

Example: avoiding a short circuit throughappropriate separation, avoiding componentfailures that result from over-dimensioning,using the failsafe principle (on switching off).

Note: When a fault occurs it can lead to theloss of the safety function.

Category 2

Safety-related parts of control systems mustbe designed so that their safety function(s)are checked at suitable intervals by themachine control system. The safetyfunction(s) must be checked: at the machinestart-up and prior to the initiation of anyhazardous situation; periodically duringoperation, if the risk assessment and thekind of operation show that it is necessary.

Risk parameters and categories

This check may be initiated automatically ormanually. Automatically, for example,the check may be initiated by a signalgenerated from a control system at suitableintervals. The automatic test should beprovided by preference. The decision aboutthe type of test depends on the riskassessment and the judgement of the enduser or machine builder. If no fault isdetected, operation may be approved as aresult of the test. If a fault is detected, anoutput must be generated to initiateappropriate control action. A second,independent shutdown route is required forthis.

Notes: In some cases Category 2 is notapplicable because the checking of thesafety function cannot be applied to allcomponents and devices. Moreover, thecost involved in implementing Category 2correctly may be considerable, so that itmay make better economic sense toimplement a different category.In general Category 2 can be realised withelectronic techniques.

The system behaviour allows theoccurrence of a fault to lead to the loss ofthe safety function between checks; the lossof safety function is detected by the check.

Category 3

Safety-related parts of control systems mustbe designed so that a single fault in any ofthese parts does not lead to the loss of thesafety function.

Whenever reasonably practicable, the singlefault shall be detected at or before the nextdemand upon the safety function. This doesnot mean that all faults will be detected. Theaccumulation of undetected faults can leadto an unintended output signal and ahazardous situation at the machine.

Category 4

Safety-related parts of control systems mustbe designed so that a single fault in any ofthese parts does not lead to a loss of thesafety function; the single fault must bedetected at or before the next demand uponthe safety functions (e.g. immediately atswitch on, at the end of a machineoperating cycle).

If this detection is not possible, then anaccumulation of faults shall not lead to aloss of the safety function.

Functional safety withEN/IEC 61508?

EN/IEC 61508 is regarded as a genericsafety standard, which deals with thefunctional safety of electrical, electronic andprogrammable electronic systems,irrespective of the application.

One of the main tasks of EN/IEC 61508 is toserve as a basis for the development ofapplication-oriented standards. Standards’committees are currently busy in the areasof machine safety with EN/IEC 62061, andprocess safety with EN/IEC 61511.Also under revision is EN 954, the standardharmonised under the scope of themachinery directive, which in future will belisted as EN/ISO 13849.These sector-specific standards areintended to continue the principleapproaches of EN/IEC 61508 and toimplement the requirements for the relevantapplication area in a suitably practicalmanner.

What is the legal statusof IEC 61508?

As EN/IEC 61508 is not listed in the OfficialJournal of the European Communities forimplementation as a European directive, itlacks the so-called "presumption effect". If

Risk assessment

Under the terms of the machinery directive,a machine manufacturer must assess thehazards in order to identify all the hazardsthat apply to his machine. He must thendesign and construct the machine to takeaccount of his assessment. Thisrequirement also applies to operators whoact as manufacturers under the terms of themachinery directive. For example, this mayoccur with machines that are interlinked orfor machinery that has been upgraded andsubstantially modified.

EN 1050 contains "Principles for riskassessment" on machinery. Theseapproaches can be called upon as part of acomprehensive analysis. EN 954-1 expandson EN 1050 with regard to the assessmentof safety-related parts of control systems.

The hazards emanating from a machine maybe many and varied, so for example, it isnecessary to consider not just mechanicalhazards through crushing and shearing, butalso thermal and electrical hazards andhazards from radiation. Risk reduction istherefore an iterative process, i.e. it iscarried out before and during the planningphase and after completion of the plant ormachine.

Safety assessments

Before using a unit it is necessary toperform a safety assessment in accordancewith the Machinery Directive. The safetysystem guarantees functional safety, but notthe safety of the entire application. Youshould therefore define the safetyrequirements for the plant as a whole, andalso define how these will be implementedfrom a technical and organisationalstandpoint.

General safety requirements

Always ensure the following safetyrequirements are met:• Only install and commission the unit if

you are familiar with the information inthe operating instructions or thistechnical catalogue, as well as therelevant regulations concerning healthand safety at work and accidentprevention.

• Only use the unit for the purpose forwhich it is intended and comply with boththe general and specific technical details.

• Transport, storage and operatingconditions should all conform to EN60068-2-6, 01/00 (see general technicaldetails on the individual units, in thechapter entitled "Unit-specificdescriptions").

You must observe the warning notes givenin other parts of this technical catalogue.These are highlighted visually through theuse of symbols.

NOTICEFailure to keep to these safetyregulations will render the warrantyinvalid.

Intended use

The units’ intended use depends on theindividual unit and is therefore explained inthe chapter entitled "Unit-specificdescriptions".

Operation of the safety switch PSENmag

Safety switches in the PSEN product rangeact in conjunction with an actuator in non-contact, magnetic operation. Each safetyswitch has an approved actuator. Togetherwith an authorised evaluation device theyform an approved, complete solution.

The safety switches are available withdifferent contact combinations (N/C / N/O,N/O / N/O). If the actuator is within theresponse range, the magnets switch thereed contacts on the safety switch. If theactuator is outside the response range(safety gate open), the reed contacts on thesafety switch will switch. On some safetyswitches this is signalled by a red LED.

Protection against defeat

Safety switches from the PSEN range aredesigned to guarantee security againstmanipulation through protection againstdefeat in accordance with VDE 0660.

Selection criteria for safety switchesPSENmag

• Switching distances• Switch type (e.g. N/C / N/C combination)• Design (compact, round, square)• Type of evaluation device• Connection to evaluation device

- directly to the safety switch (singleconnection)

- via an interface to the safety switch(series connection of several safetyswitches)

• Category to be achieved in accordancewith EN 954-1 and EN 60947-5-3

• LED to display switch status• Type of cable connection on the safety

switch (plug-in with screw connection,straight or angled)

• Housing material, application area

Switching distance:Safety switches with different switchingdistances are available for differentapplications, e.g. with an assured operatingdistance sao of 3 or 8 mm.

A high lateral and vertical offset can beachieved with long switching distances. Thiswill provide greater tolerances forinstallation and even less sensitivity towardsspring-back or swinging from safety gates.

Assured switching distances:• Assured operating distance sao:

This is the distance from the sensingface, within which the presence of thespecified target is correctly detectedunder all specified environmentalconditions, manufacturing tolerances andinternal component faults.

• Assured release distance sar

This is the distance from the sensingface, beyond which the presence of thespecified target is correctly detectedunder all specified environmentalconditions, manufacturing tolerances andinternal component faults.

Hysteresis:The assured release distance is longer thanthe assured operating distance (sar > sao).The safety switches therefore have ahysteresis. If the actuator is within sao,

vibrations up to sar will not cause the safetyswitch to de-energise.

Actuator’s direction of movement:The sensing face of the actuator ispermitted to move in parallel to the sensingface on the safety switch. Movements inwhich the actuator is tilted in relation to thesafety switch are not permitted (Fig. 4-3).

Actuator’s pass-by speed:If the safety switch is being used as aposition switch, the maximum permittedpass-by speed of the actuator is important.This must be defined so that the evaluationdevice can detect the status of the safetyswitch. This value is device-specific.

Compact structure:The safety switches are small and compactin design, enabling them to integrateperfectly into an existing workingenvironment.

With a round or square design, the safetyswitches can easily be adapted to suitinstallation requirements.

Evaluation devices:Each safety switch has an approvedevaluation device and possibly also aninterface.

Fig. 4-5: Connection cable with connector

The interface type and the number of safetyswitches that can be connected will dependon the selected evaluation device. Theinterface connects the safety switches inseries to the evaluation device. The switchstatus of the individual safety switches(safety gate open or closed) is displayedthrough LEDs and can be evaluated viaauxiliary outputs, e.g. with a PLC.

Housing material:The housing of the PSEN safety switch ismade from silicone-free PBT plastic, whichis insensitive to dirt. For details of thechemical resistance of the housing material,please refer to the table in Chapter 9,"Appendix".

Cable with connector:The cables for the safety sensors have aplug-in connection. This enables the cableand switches to be installed separately. Theplug connectors are 4-pin male M8 screwconnectors with lock. They are availablestraight or angled.

Category:Safety switches in the PSEN product rangehave two independent contacts. They areclassified as PDF-M in accordance withEN 60947-5-3 and can therefore be used forapplications up to category 4 in accordancewith EN 954-1.If an interface (e.g. PSEN i1) is used toconnect the safety switches in series, theclassification to EN 60947-5-3 is reduced toPDF-S. This means the safety switches canbe used for applications up to category 3 inaccordance with EN 954-1.

Application areas:Thanks to the high protection type IP65/67,integral protection against defeat and longservice life, the safety switches are suitablefor use:• In mechanical engineering• In areas with rigorous hygiene

requirements, such as the food,packaging or pharmaceutical industry.

Operation of the PSENcode safetyswitches

PSENcode safety switches act in conjunc-tion with a coded actuator in non-contactoperation (transponder). Each safety switchhas an actuator (transponder). Together withan authorised evaluation device they forman approved, complete solution.

Two microcontrollers evaluate the inputcircuits and switch the outputs accordingly.The microcontrollers monitor each other.

If the correct actuator (transponder) is in theresponse range, signal output Y32 willswitch on. If the input circuits are alsoclosed, safety contacts 12 and 22 areswitched on and the "Input" LED illuminatesyellow.If the actuator is not within the responserange (open safety gate) or the input circuitsare not closed, safety outputs 12 and 22and signal output Y32 are blocked.If the shut down occurs via the inputs,reactivation of the outputs is only possibleafter both safety inputs are simultaneouslyde-energised (partial operation lock).

Protection against defeat

Safety switches from the PSEN range aredesigned to guarantee security againstmanipulation through protection againstdefeat in accordance with VDE 0660.

Selection criteria for PSENcode safetyswitches

• Coding- Coded actuator: Safety switch only

accepts PILZ actuators- Fully coded actuator (unique code):

The actuator has a unique electroniccoding. The safety switch only reactsto a single actuator.

- Fully coded actuator (unique code,teachable): The actuator has a uniqueelectronic coding. The safety switchonly reacts to a single actuator. Newactuators can be taught in via alearning procedure at the safety switch(max. 8 additional learning procedures).

• Application area- Safety switch with ATEX approval for

use in potentially explosive atmos-pheres.

Directions of actuation

PSENcs safety switches have 5 differentsensing faces.

• Typical operating distance so:This is the distance from the sensingface, within which the presence of thespecified target is typically detectedcorrectly.

• Release distance sr:This is the distance from the sensingface, beyond which the absence of thespecified target is correctly detectedunder all specified environmentalconditions and manufacturing tolerances.

• Typical release distance:This is the distance from the sensingface, beyond which the absence of thespecified target is typically detectedcorrectly.

• Assured release distance sar:This is the distance from the sensingface, beyond which the absence of thespecified target is correctly detectedunder all specified environmental condi-tions, manufacturing tolerances andandandandandinterinterinterinterinternal componentnal componentnal componentnal componentnal component faults.

Hysteresis:The typical release distance is longer thanthe typical operating distance so. The safetyswitches therefore have a hysteresis. If theactuator is within so, vibrations up to thetypical release distance will not cause thesafety switch to de-energise.

Fig. 4-6: Directions of actuation

Switching distance

A high lateral and vertical offset can beachieved as a result of the long switchingdistances. This will provide greater toler-ances for installation and even less sensitivitytowards spring-back or swinging fromsafety gates.• Assured operating distance sao:

This is the distance from the sensingface, within which the presence of thespecified target is correctly detectedunder all specified environmentalconditions and manufacturing tolerances.

Installation guidelines

Safety switch and actuator• Keep away from iron swarf• Do not expose to strong magnetic fields• Do not expose to heavy shock or

vibration• Do not use as a limit stop• Where possible do not install on top of

ferromagnetic material (changes in theswitching distances can be expected).In this case, units in the square designcan use the spacer, order number534 310.

The distance between two systems madeup of safety switch and actuator must be atleast 25 mm (see installation example,"Safety switches on swing gates").

Fig. 5-1: Install facing each other and inparallel

Attachment

Attach the safety switch to the fixed part ofthe safety device.

Square design:Safety switches and actuators shouldonly be secured using M4 screws with aflat head (e.g. M4 cheese-head or panhead screws). Torque setting max. 1 Nm.Use screws made of non-magneticmaterial (e.g. brass).

Round design:Secure the safety switch using the M30nuts provided.The torque setting for the M30 nuts ismax. 300 Ncm.The actuator should be secured using anM4 or M5 screw made of non-magneticmaterial (e.g. brass).

CAUTION!The actuator should be securedpermanently to guarantee securityagainst manipulation.

Adjustment

• The safety switch may only be used witha corresponding actuator.

• The actuator must not make contact withthe safety switch. Please note theminimum switching distance stated in thetechnical details.

• Always test the function with one of theapproved evaluation devices.

• Some safety switches have an LED. TheLED lights when the contacts areunoperated (safety device open or safetyswitch and actuator wrongly adjusted).The LED is in the safety switch’s N/Ccircuit. The LED goes out when thecontacts are operated.

INFORMATIONFurther information about theswitching distances (operating andrelease distance) and the maximumpermitted lateral and vertical offsetcan be found in the chaptersentitled "Description" and "Unit-specific descriptions".

Installing the interfaces PSEN i1 andPSEN ix1

CAUTION!The unit should be installed in acontrol cabinet with a protectiontype of at least IP54.

• Use the notch on the rear of the unit toattach it to a DIN rail.

• Secure the unit on a vertical DIN rail(35 mm) using a retaining bracket or endangle.

On units with a round design, make surethat the two notches are exactly oppositeeach other. A nib on the actuator prevents ittwisting.

• LED indicator for:- Status, actuator- Status, inputs- Supply voltage/fault


Teaching in the actuator

Initially teaching in an actuator:The first actuator detected by the safetyswitch is automatically taught in as soon asit is brought into the response range.To teach in a new actuator(PSEN cs2.1p only):1. Bring the actuator to be taught in into the

response range of the safety switch asthe only transponder. As soon as theactuator is detected, the operatingindicator switches to a yellow flashinglight.

2. After a waiting period of 20 s haselapsed, the operating indicator switchesto yellow flashes. Trigger a system resetin the next 120 s by interrupting thepower supply.

3. After the device is switched back on, thelearning procedure has successfullyconcluded and the number of permittedadditional learning procedures is reducedby 1.

Notice!The actuator must not be removed duringthe learning procedure

INFORMATIONAn actuator can be taught just once

EN 954-1• Transponder technology• Fully-coded actuator:

The actuator has a unique electroniccoding. The safety switch only reacts to asingle actuator.New actuators can be taught in via alearning procedure at the safety switch(max. 8 additional learning procedures).

• Assured operating distance:15 mm

• Typical operating distance:21 mm

• Release distance:30 mm

• Assured release distance:40 mm

• Dual-channel operation• 2 safety inputs for series connection of

several safety switches• 2 safety outputs• 1 signal output

• LED indicator for:- Status, actuator- Status, inputs- Supply voltage/fault


Teaching in the actuator

Initially teaching in the actuator:The first actuator detected by the safetyswitch is automatically taught in as soon asit is brought into the response range.To teach in a new actuator:1. Bring the actuator to be taught in into the

response range of the safety switch asthe only transponder. As soon as theactuator is detected, the operatingindicator switches to a yellow flashinglight.

2. After a waiting period of 20 s haselapsed, the operating indicator switchesto yellow flashes. Trigger a system resetin the next 120 s by interrupting thepower supply.

3. After the device is switched back on, thelearning procedure has successfullyconcluded and the number of permittedadditional learning procedures is reducedby 1.

Notice!The actuator must not be removed duringthe learning procedure

INFORMATIONAn actuator can be taught just once

Safety assessments

Before using a unit it is necessary toperform a safety assessment in accordancewith the Machinery Directive. The units asindividual components guarantee functionalsafety, but not the safety of the entireapplication. You should therefore define thesafety requirements for the plant as a whole,and also define how these will beimplemented from a technical andorganisational standpoint (e.g. refer to BIA[BG Institute for Occupational Safety]Report 1997-06).

Features

● 1 E-STOP button● 2 safety gates● Dual-channel with detection of shorts

across contacts● 1 PLC enabling signal● 1 instantaneous load shutdown

DescriptionTwo safety gates are used to protect ahazardous area. The machine’s motor willonly start if:● Both safety gates are closed and● The E-STOP button has not been

operated and● The PLC enabling signal (not safety-

related) is present.

If one of these conditions is not met, thesignal at outputs A4.o4 and A4.o5 willswitch from high to low and the motor willbe switched off.

Feedback loopN/C contacts K3 and K4 on contactors K3and K4 are connected to the feedback loopinput A4.i9.

ResetE-STOP and safety gate monitoring must beactivated through the reset button S11(monitored reset). If the conditions forstarting the motor have been met and thefeedback loop is closed, operation of theplant is enabled.

Safety assessment● The PNOZ m1p and contactors

K3 and K4 must be installed in a singlelocation.

● If a switch contact (A4.i0 ... A4.i5) isoverridden, this will be detected as anerror at the next operation. Safetyoutputs A4.o4 and A4.o5 will carry a lowsignal.

● A short circuit between 24 VDC andinputs A4.i0 ... A4.i5 will be detected asan error. All the safety outputs will carry alow signal.

PSEN 2.1p-10Machine hoods with 3 x 2 safety switches, Category 3, EN 954-1

Features

● 3 interlinked safety gates● 1 instantaneous load shutdown

Description

Monitoring function3 machine hoods are fitted on a machine forservice reasons. The machine is shut downas soon as one of the 3 machine hoods isopened.Each machine hood has 2 safety switches.The PSEN i1 interface switches the N/Ccontacts on the sensors in parallel and theN/O contacts in series. The PNOZ e3.1pswitches the machine on or off, dependingon the status of the safety switches.If all the machine hoods are closed, safetyoutputs 14 and 24 will carry a high signal. Ifa machine hood is opened, the outputsignals will switch from high to low andcontactors K1 and K2 will de-energise.The unit is to use both contactors K1 andK2 at safety outputs 14 and 24 to switch asingle load.

Feedback loopThe unit has a separate feedback loop. TheN/C contacts on the contactors areconnected to the feedback loop input Y6.When the unit is started, a test is carried outto check whether both N/C contacts areclosed, i.e. whether the contactors have de-

energised. If one of the contacts is open,the safety outputs will retain the low signal.The unit will not be ready for operationagain until the feedback loop is closed andthe input circuits have been opened andthen closed again.If the signal at the safety outputs switchesfrom high to low, the N/C contacts mustclose within a max. of 150 ms. If onecontactor fails to de-energise, thecorresponding N/C contact will remainopen; an error is detected and is displayedas a flashing pulse (1, 8). It will not bepossible to switch the unit back on until theerror has been rectified and the supplyvoltage has been switched off and then onagain.

ResetIf all the machine hoods are closed and thefeedback loop is closed, the unit can bestarted by pressing the reset button S7(monitored reset).

Safety assessment

● The PNOZe3.1p and contactorsK1 and K2 do not have to be installed ina single location.

● Errors within the safety gate seriesconnection may remain undetected when- the safety gates are opened

simultaneously.- the sequence in which the safety gates

open is unfavourable.

NOTICEIn order to detect every fault, onlyone safety gate may be opened at atime or each safety gate must betested individually.

● If a switch contact in the input circuit isoverridden, this will be detected as anerror the next time the PNOZelog isoperated. Safety outputs 14 and 24 willcarry a low signal. The error is reset by

operating another switch contact; after arestart the safety outputs will again carrya high signal.

● A short circuit between 24 VDC and theinput circuits (S12, S24) will be detectedas an error after the next operation of theaffected input circuits, depending on thelocation of the error. Safety outputs 14and 24 will carry a low signal.

● A short circuit between 24 VDC and asafety output will be detected and thesafety outputs will carry a low signal. Theload will be switched off via the secondsafety output.
