...to provide passable protection into risk areas!Both light curtains and light grids can often be usedas passable protection into a risk area. This is calledpassable protection because it is possible to get inbehind the safety device. Common applications arerobot installations, openings for in and out passage ofmaterial, etc. The choice between light curtain or lightgrid is often a question of available safety distance,reach and price. Light curtains are often chosen forshort safety distances light grids are chosen for longreach — up to 50 m — and for a low price.

Why should I use Safety Light Curtains and Grids?...to provide operator protection during production!A safety light curtain can be used on a machine or in a production plant in the same way as a hatch or door.There are great differences though when it comes to the component installation and functionality. When alight curtain is mounted on a hazardous machine, weare not only concerned with the response times of thesafety systems, but also the Depth Penetration Factors.It is possible for the operator’s fingers or hands topass through the light curtain a certain distance beforebeing detected. This becomes the Depth PenetrationFactor. This distance must also be entered into theMinimal Safety Distance Calculation for the machine(see page 4).

It is also very important that the level of safety of the light curtain with dual supervised outputs be con-tinued throughout the rest of the stopping control circuit. Even valves and contactors, which ultimatelycontrol dangerous movements, normally have to beredundant and monitored.

Automatic MachinesFor light curtains on automatic machines there shall bea reset function which is active when the machine isset for automatic production, whether or not it is a pass-able protection. After an engagement one must firstuse a reset function, then the restart of the cycle shouldbe made with a separate starting device. The samereset applies for machines with semi-automatic drives.

Mechanical and Hydraulic PressesLight curtain applications are often categorized by thetype of guarding required. Protecting an operator fromthe hazards associated with material positioning orwhere a process is performed is called Point of Opera-tion Guarding. The point of operation is often calledthe Zone of Hazardous Operation or the Pinch Point.

This type of guarding is associated with mechanicaland hydraulic power presses, molding presses, stamp-ing, forming, riveting, eyelet and automated assemblymachinery. Light curtains used in these applicationsare typically selected for finger and hand protection.

During Manual Servicing of MachinesWith manually operated machines where one or more operators move parts in and out between every cycle.This type of application is the most risky because thenumber of engagements into the machine’s dangerousarea is often several times per minute.

How do Light Curtains and Light Grids work?Both Light Curtains and Light Grids utilize optical transmitter and receiver units. Beams of infrared light are sent to the receiver from the transmitters. When a light beam is interrupted, a dual stop signal is given to the dangerous machines inside the light curtain/grid protected area.

What is the difference between a Light curtain and a Light Grid?A Light Curtain has several beams that are placed closely together, while a Light Grid consists of only one, two, three or four light beams.

The beams are closest on a Light Curtain that isused for finger detection, with a resolution of 14mm.Light Curtain beams are at their widest spacing when

What are the safety requirements for an Optical Protective Device?High safety demands are stated in the standards EN61 496-1 and prEN 61 496-2 which deal with opticalprotective devices. The main demands are on a safestopping function and that light from light sourcesother than the transmitter or other disturbances donot affect the safety function.

Depending on how the safety function is built upthere are safety components of type 2 and 4 accord-ing to EN 954-1 and EN 61496, Part 1 and Part 2.

Type 4, which has the highest safety level, statesthat a fault is not allowed to affect the safety functionand that the fault shall be detected by the outputsopening immediately or that they do not reconnectafter being disconnected. Maximum allowed apertureangle for the light is +_ 2º.

Type 2 states that a simple but monitored safetyfunction is required, which means that the safety func-tion shall be monitored through periodic tests whichopen the output when a fault occurs. Between the test-ing times there can be faults which result in the safetycomponent malfunctioning. The test function can eitherbe built into the safety device or an external unit (e.g.the machine’s control system) can initiate a test. Maxi-mum allowed aperture angle for the light is +_ 4º.

Light curtains and light grids are included amongthe products in the machine directive’s appendix 4,which means that an external certifying procedurewith an officially recognized institution is called for.

used for thigh detection, with a resolution of 90mm.For Light Grids the beams are normally placed at a

relative distance of 300 to 500mm.

For finger and hand detection Safety Light Curtains:

Dpf in mm = 3.4 x (Os – 6.875mm)Dpf in inches = 3.4 x (Os – 0.275”)

Where:Os = minimum object sensitivity or resolution.

For horizontal mounted Safety Light Curtains:

Dpf in mm = 1200mmDpf in inches = 48”

For multi beam Safety Light Grids:

Dpf in mm = 1200mm for a 2 beam system with beams spaced 600mm apart.

Dpf in inches = 48” for a 2 beam system with beamsspaced 600mm apart.

Dpf in mm = 900mm for a 3 beam system with beams spaced 450mm apart.

Dpf in inches = 36” for a 3 beam system with beamsspaced 450mm apart.

Minimal Safe Distance CalculationThe Minimal Safe Distance Calculation shall guar-antee that a person is not able to reach a dangerousmachine part before the machine movement hasstopped. This is calculated with the formula as called

for from the ANSI B11.19-2003 Performance Criteriafor the Design, Construction, Care and Operation ofSafeguarding Standard.

Tr = response time of the safeguarding device including its interface.

Tspm = the additional stopping time, in seconds, allowed by the stopping performance moni-tor before it detects stop time deterioration.

Dpf = maximum travel towards the hazard within thepresence sensing safeguarding devices (PSSD)field that may occur before a stop is signaled.Depth penetration factors will change depend-ing on the type of device and application.

Ds = [K x (Ts + Tc + Tr + Tspm)] + DpfWhere:Ds = minimum safe distance between the

safeguarding device and the hazard.K = hand speed constant: 1.6 m/sec (63 inches/sec)

minimum based on the movement being thehand/arm only and the body being stationary.

Ts = worst stopping time of the machine/equipment.Tc = worst stopping time of the control system.

Note: Ts + Tc are usually measured together with the Jokab Safety Stop Time Analyzer.

K = The maximum speed at which an individual can approach the hazard, expressed in inches per second.

To quote ANSI B11.19-2003: “The factor K is the speed constant and includes hand and body movements of an individual approaching a hazard area. The following factors should be considered when determining K: a) Hand and arm movement; b) Twisting of the body or shoulder, or bending at the waist; c) Walking or running.

One of the accepted values for K is the hand speed constant (it is usually considered as the horizontal motion of thehand and arm while seated). Its common value is 63 in./s although other values (typically higher) are also used. Thehand speed constant does not include other body movements, which can affect the actual approach speed.Consideration of the above factors should be included when determining the speed constant for a given application.”

Resolution for hands.

Example 1: With the aid of the JokabSmart Stop Time Analyzer, a mechanicalpower press has a measured stopping time(Ts + Tc) of 325 ms. This includes both thestopping time of the machine as well as thestopping time of the control circuit. Theresponse time of the Focus Safety LightCurtain F4-35-900 with 35mm (1.38”) resolu-tion and 900mm (35.43”) protective height is20ms (Tr). The stop time break monitor is setfor 400 ms.

Ds = [K x (Ts + Tc + Tr + Tspm)] + DpfDs = [1.6m/s x (325ms + 20ms + 75ms)] + 95.63mmDs = [63inch/s x (325ms + 20ms + 75ms)] + 3.76”Ds = [1600mm/s x 420ms] + 95.63mmDs = [63inch/s x 420ms] + 3.76”Ds = [1600mm/s x .420s] + 95.63Ds = [63inch/s x .420s] + 3.76”Ds = 672mm + 95.63mmDs = 26.46” + 3.76”Ds = 767.63mmDs = 30.22”

Tspm = 400ms – (Ts + Tc)Tspm = 400ms – 325msTspm = 75ms

Dpf = 3.4 x (35mm – 6.875mm) Dpf = 3.4 x (1.38” – 0.275”)Dpf = 3.4 x 28.125mm Dpf = 3.4 x 1.105”Dpf = 95.63mm Dpf = 3.76“

In this example the safety light curtain must be mountedno closer than 767.63mm(30.22”) from the hazardouspinch point.

Example 2: With the aid of the Jokab Smart Stop Time Analyzer, a robotic loader has a measured stop-ping time (Ts + Tc) of 175 ms. This includes both thestopping time of the machine as well as the stoppingtime of the control circuit. The response time of the

horizontally mounted Focus Safety Light Curtain with35mm (1.38”) resolution is 24ms. The depth of pene-tration factor is fixed at 1200mm (48”).

Ds = [K x (Ts + Tc + Tr)] + DpfDs = [1.6m/s x (175ms + 24ms)] + 1200mmDs = [63inch/s x (175ms + 24ms)] + 48”Ds = [1600mm/s x 199ms] + 1200mmDs = [63inch/s x 199ms] + 48”Ds = [1600mm/s x .199s] + 1200mmDs = [63inch/s x .199s] + 48”Ds = 318.4mm + 1200mmDs = 12.54” + 48”Ds = 1518.4mmDs = 60.54”

In this example the horizontal safety light curtain must be at least1518.4mm (60.54”) from the hazardous pinch point.

Example 3: With the aid of the Jokab Smart Stop Time Analyzer, a transfer gantry system has a meas-ured stopping time (Ts + Tc) of 212 ms. This includesboth the stopping time of the machine as well as thestopping time of the control circuit. The responsetime of the Focus Safety Light Grid F4-K3-900 with

300mm (11.81”) beam spacing and 900mm (35.43”)protective height is 14ms (Tr). For a 3 beam SafetyLight Grid the depth of penetration factor is fixed at900mm (35.43”).

Ds = [K x (Ts + Tc + Tr)] + DpfDs = [1.6m/s x (212ms + 14ms)] + 900mmDs = [63inch/s x (212ms + 14ms)] + 35.43”Ds = [1600mm/s x 226ms] + 900mmDs = [63inch/s x 226ms] + 35.43”Ds = [1600mm/s x .226s] + 900mmDs = [63inch/s x .226s] + 35.43”Ds = 361.6mm + 900mmDs = 14.24” + 35.43”Ds = 1261.6mmDs = 49.67”

Focus Safety LightCurtains and Light GridsIf your company is concentrating on machine safety to protect your employees and manufacturing operations,then you need the new Focus Safety Light Curtains andLight Grids. The latest in a long list of machine safetyinnovations from Jokab Safety North America, the Focusproduct line is designed to be the most control reliable anddependable presence sensing devices on the market today.

The Focus Curtains and Grids offer unsurpassed ease of installation and alignment, plus built-in muting capabil-ities. They are rated Category 4 Safety Level and havereceived all necessary national and international approvals.

Focus Curtains and Grids provide muting flexibility withinputs provided for partial or complete muting. Featuresinclude bypass lamp supervision, automatic or manualsupervised reset, 2 supervised PNP safety outputs withcross-circuit monitoring, and M12 connections. LEDsprovide easy alignment and indication of pollution, powersupply and output status. Outputs are overload protectedfor a maximum load of 500mA. Floating blanking is offeredas an optional feature in the FB units.

Focus comes standard with a prereset function forincreased operator safety for applications where the oper-ator can physically pass through the light curtain field.This function prevents inadvertent reset of a cell or machine,thus requiring a prereset button to be activated before thefinal reset function can occur. (Not available with FB units.)

Muting and OverrideThe “muting” and “override” functions are available on all Focus Curtains and Grids and is enabled directly when anindication lamp is connected. Muting implies that one ormore segments or the whole light curtain can be bypassedduring in and out passage of material.

In the Focus with muting there is also an override func-tion which makes it possible to bypass the light curtain/grid(i.e. activate the outputs if a machine start is necessary)even if one or more light beams are interrupted. This isthe case when the muting function is chosen and the Aand B inputs are activated. If during the muting operationa loading pallet has stopped inside the safety field after avoltage loss, the override function is used to enable thepallet to be driven clear.

Floating Blanking or Fixed BlankingIt is also possible to obtain the Focus Curtains and

Grids with either “floating blanking” or “fixed blanking”.Floating blanking makes it possible to ‘disconnect’ adefined number of beams from the safety field. Theobject is then free to move in the safety field without thesafety function being triggered. During fixed blanking, theobject is not able to move in the safety field. The otherbeams are active with normal resolution. During blankingapplications, the object must remain in the sensing field.

Focus consists of two units, a transmitter unit and a receiver unit. All the optical units are scanned regularly so that all objects that are placed betweenthe transmitter and the receiver will be detected.

If any light beam is interrupted, the dangerousmachine movement will be stopped by the outputsfrom the light curtain. The reaction time for the Focusvaries from 14ms to 45ms, depending on the numberof beams in the light curtain. The five LEDs in thereceiver and the two in the transmitter show the sta-tus of the light curtain/grid.

Safety Outputs OSSD1 and OSSD2Focus has two PNP outputs — OSSD1 and OSSD2. If the load to be switched is alternating current orrequires a higher current than 500 mA, then oneshould use a safety relay, e.g. RT9, Pluto PLC or theFRM-1 unit (converts the outputs to relay contacts)from Jokab Safety. The FMC-Tina and Tina 10A/10Bconverts the outputs to a dynamic signal for connec-tion to Pluto or Vital. Pluto can also work directly withthe OSSD outputs.

Focus ResetOn every Focus there are inputs for reset and other functions — Reset, Alignment and Override (bypassingis only possible when muting is used).Reset possibilities:• Automatic reset — when the light field is free the

outputs are closed directly.• Manual reset — Focus gives a ready signal when

the light field is free and the reset button has beenactuated.

• Time reset — during manual reset. To reset the Focusa pre-reset button must first be actuated and after-wards, within 8 seconds, a reset button outside the risk area must be actuated.

Choice of reset:Reset alternatives are chosen with double change-over switches in the Focus receiver.Note: For further technical information, please reference the Focus Operating Manual.

AutomaticReset

ResetOn the servicing side (i.e. the side/sides where there is an operator who moves parts in and out) there shallbe a separate reset function for the light curtain. Ifthere are several light curtains (e.g. on the front andback) there shall be one for each. If the light curtain is actuated during a dangerous movement, the pressshould not be able to restart without being reset.During engagement after the end of the cycle noreset is needed.

For a light curtain which is placed as protection onboth sides which are not servicing sides, there shallbe a reset button which always needs to be activatedafter an engagement.

Supervised Manual ResetWhen a light curtain/light grid is interrupted it will givea stop signal to dangerous machines within the riskarea it protects. For a new start of the machine thelight curtain/light grid has to be reset. This is donewith the reset button (Figure 1) which is placed whereit cannot be reached from within the area which isprotected. There are high requirements on the resetfunction — neither a short circuit nor a componentfault shall give automatic reset. When the reset buttonhas been affected the outputs are activated and themachine can initiate.

Automatic ResetAutomatic reset can only be used when it is impos-sible to get between the safety light curtain and thehazardous pinch point. When the operator removeshis hands from the protective field the dual safetyoutputs will energize starting the next machine cycleimmediately.

Pre-Reset SolutionIf the machine start button is not locatedsuch that you have a clear view of the entire work area, additional safe guards must be used. Typical devices include Safety Laser Scanners, Safety Mats and Horizontal Safety Light Curtains.

Focus Safety Light Curtains address this requirement without costly additional safety devices. By selecting the Pre-Reset mode through the Focus Receiver’s internal dipswitches, the primary require-ment for accidental resets is satisfied. The Pre-Reset must first be cycled, which gives a clear view of the work area, then no longer than 7 seconds later the Final Reset must be cycled.

Mounting Focus Light Curtains and Light GridsVertical Safety Light CurtainsA vertically mounted safety light curtain that is used as the primary safety device must be mounted sothat the bottom beam is no higher than 300mm (12”)from the ground. Mounting heights above 300mm(12”) may require supplemental safeguarding to pre-vent crawling or ducking under the horizontal lightcurtain. The top beam must be no lower than900mm for reach over applications and 1200mm (48”)for reach through applications. Mounting heightslower than this will require additional safeguarding.

Horizontal Safety Light CurtainsA horizontal safety light curtain that is used as the primary safety device must be mounted no higherthan 300mm (12”) from the ground. Mounting heightsabove 300mm (12”) may require supplemental safe-guarding to prevent crawling or ducking under thehorizontal light curtain. The minimal length the safetylight curtain can be 1200mm (48”) long.

The formula below is for mounting differentresolutions from a horizontal surface.Height = 15 x (Os - 50mm)Height = 15 x (Os - 2”)Note: Os represents the beam spacing.

Vertical Perimeter Safety Light GridsA vertically mounted safety light grid must be mounted such that the bottom beam is no higherthan 300mm (12”) from the ground. If the light gridis of only 2 beams then the second beam must belocated 900mm (36”) from the ground. For a 3 or 4beam system the top beam must be 1200mm (48”)above the ground.

A solution with four sensors and TWO movement directions for material transport.

Muting (Bypassing)Bypassing may be needed for different reasons. One of the most common reasons for bypassing isduring in and out feeding of material on a conveyor,auto industrial trucks, etc. Another common applica-tion is bypassing while passing with a three-positiondevice to the risk area.

Important aspects for bypassing are that it shouldbe safe, not be activated by mistake and be difficultto defeat. In other words, it should give a reliablebypassing when a loading carrier comes but notallow a human to pass. To achieve the highest safetylevel a dual and supervised bypassing system isneeded — usually with at least two independent sig-nals. If this is done with sensors, it is recommendedthey be of different kinds, because the probability ofthem both malfunctioning for the same reason (e.g.common mode failure) is eliminated. An example of asolution is to use a mechanical limit switch and aphotocell sensor.

To avoid deliberate defeating/manipulation of thebypassing sensors/signals a safety relay or a safety

PLC is connected, thereby monitoring that both sen-sors are activated and deactivated in every bypass-ing cycle.

The amount of variants of bypassing systems arealmost infinite, depending on the specific require-ments of each plant/machine. For Focus there are anumber of bypassing possibilities prepared.

Focus Modular Muting CapabilitiesThe Focus Safety Light Curtain offers the selection of complete muting of the protective field during the inand out passage of material. Through dipswitch settingsin the Focus standard version, it is also capable ofmuting only specific modules within the protective field.

The Focus is capable of muting independent beammodule packets or a combination of them (up to 4).

For example, a box travels down a conveyor andinstead of muting the entire light curtain you canmute only modules 1 and 2 — which equates to theheight of the box — allowing continual protection onthe remaining Safety Light Curtain modules.

The module size is directly dependent on theFocus Light Curtain resolution and length.

The test/reset button shall be placed so the operatorcan see the protected area during reset, testing andbypassing, It should not be possible to reach the but-ton from within the risk area.

The LMS lamp for indication of muting and bypas-sing shall be placed so that it can be seen from alldirections from where it is possible to access the dangerous area.

If photocells are used as muting sensors, the sensorreceivers should be assembled on the light curtain’stransmitter side to minimize the interference risk.

The system is protected against dangerous func-tions caused by damage on the transmitter cableand/or the receiver cable. However, we recommendthat the cables be protected so that physical damageto them can be minimized.

MF-T and MF-L are muting units with integrated photocells in the same profile type as the Focus LightCurtain/Grid. No additional sensors are required becausethe muting units contain the required components. MF-T/MF-L is connected directly to Focus with M12connectors.

MF-T (Option 1)MF-T contains four photocells — A1, B1, B2 and A2 —arranged as shown. they are configured for installationswhere material is transported “in” or “out”— or in bothdirections “in and out”.Note: All standard Focus Light Curtains/Grids are deliv-ered connected to function together with the MF-T.

MF-L (Option 2)MF-L contains two photocells — A1 and B1— which are actuated before and by material exiting through the lightcurtain/grid. The light curtain/grid remains bypassedjust prior to the exit of the material.Note: MF-L Reflex unit is primarily intended for material transport “out” of a working area. The standard Focus LightCurtain/Grid delivered does not function together with theMF-L Reflex version. The Focus Light Curtain/Grid L versionneeds to be ordered separately, as well as the MF-L unit.

FOCUS MF-L

OUT of risk area

MF-T Reflex and MF-L Reflex are muting units with integrated retro-reflective photocells in the same profile type as the Focus Light Curtain/Grid. No additional sensors are required because the muting units contain the required components. The Reflex series simplifies the set up of muting sensors, as only 1 side requiresa cable connection. The reflective side is a polarized reflector bar. MF-T Reflex and MF-L Reflex are connected directly to the Focus Receiver with M12 connectors.

MF-T Reflex (Option 3)MF-T Reflex contains four transmitters/receivers and a separate reflector unit. Range 6m. Used in the muting mode for transport of material into and/or out of hazard-ous areas. For other func-tions refer to Option 1. This unit, together with light beam F4-K1C-500 provides electrical connections on only one side.

MF-L Reflex (Option 4)MF-L Reflex contains two transmitters/receivers and a separate reflector unit. Range 6m. Used in the muting mode for transport of material into and/or out of hazardous areas. For other functions refer to Option 2. This unit, together with light beam F4-K1C-500 provides electrical connections on only one side.Note: MF-L Reflex unit is primarily intended for material transport “out” of a working area. The standard Focus Light Curtain/Grid delivered does not function together with the MF-L Reflex version. The Focus LightCurtain/Grid L version needs to be ordered separately, as well as the MF-L unit.

Wet Wash Down Tubes are used for protection againstwater (or dust) where extreme washing conditions areencountered. The protective encapsulation rating (IP68)now enables Focus Light Curtains and Light Beamsto be used for such applications as the food industry,where the use of high pressure washing for cleaningmachinery often occurs.The draining and throughventilation capabilitiesmean that condensationcan be avoided.

Wet, with Focus LightCurtains/Beams, is pre-assembled complete with cabling on request.During installation on amachine, a Wet unit canbe adjusted by +/- 20ºwith the accompanyingangle bracket. The plastictube is rotatable and theoutside is easy to clean.

A dipswitch at the cable connection of the light curtainreceiver enables a choice of whether a blanking functionis to be used. Once this choice has been made, pro-gramming of the unit in the light field is made easy byusing the Blanking Programmer BP1.

If the extent of the object in the protected field thenchanges, the light curtain can be reprogrammed — only 11 seconds after the push button on the front of the BP1 has been pressed.

The BP1 is easily connected, in series with the cable to the light curtain receiver unit, using the M12 connector and the free length of the unit’s cable.

BP1 Blanking ProgrammerA Quick Way to Program Blanking

The BPI must be removed before power is applied to the machine controls.

The JSRL-3 Laser Aligner facilitates alignment of lightbeams or light curtains, particularly when the solutioninvolves one or more mirrors.

The JSRL-3 is simply secured by the accompanyingelasticated tape around the transmitter and receiverunit, which must be located so that the flat rear of theunit is up against the front glass of the light curtain.When the Laser Aligner is switched on, the red laserspot must be visible — if appropriate via a mirror — atthe corresponding unit.

The JSRL-3 contains two type AAA batteries that arechanged by unscrewing the bottom end lid.
