S300


Product description

3.3 FunctionThe S300 safety laser scanner operates correctly as a protective device only if thefollowing conditions are met:

� The control of the machine, system or vehicle must be electrical.

� After integration in the control it must be possible to transfer the dangerous machine,system or vehicle state to a safe state using the OSSDs on the S300 at any time, i.e.before a person has reached the hazardous point or hazardous area.

� The S300 must be mounted and configured such that it detects objects as they enterthe hazardous area (see chapter 4 “Mounting” on page 37 and chapter 8“Commissioning” on page 74).

3.3.1 Principles of operation

The S300 is an optical sensor that scans its surroundings in two dimensions using infraredlaser beams. It is used to monitor hazardous areas on machines or vehicles.

The S300 works on the principle of time of flight measurement. It sends out very shortpulses of light (S). At the same time an “electronic stopwatch” is started. When the light isincident on an object, it is reflected and received by the safety laser scanner (E). From thetime between sending and reception (∆t) the S300 calculates the distance to the object.

S300


Product description

In the S300 there is also a mirror rotating at constant speed that deflects the light pulsessuch that they cover an arc of 270° �. In this way an object can be detected in theprotective field within 270°.

The S300 sends a pulse of light with an angular resolution of 0.5°. In this way resolutionsfrom 30 to 70 mm can be achieved independent of the length of the protective field !

Due to its active scanning principle, the S300 does not require receivers or reflectors. Thishas the following advantages:

� Your installation effort is lower.

� You can easily adapt the monitored area to the hazardous area on a machine.

� In comparison with contact sensors, electro-sensitive scanning is nearly wear-free.

S300


Product description

3.3.2 Field set comprising of protective field and warning field

The S300 protects the hazardous area on a machine or a vehicle using the protectivefield �. As soon as the safety laser scanner detects an object in the protective field, itswitches the OSSDs to the OFF state and thus initiates the shutdown of the machine orstop of the vehicle.

You can define the warning field such that the safety laser scanner detects an objectbefore the actual hazardous area and e.g. triggers a warning signal.

The maximum distance at which the safety laser scanner can detect an object is definedby the distance measuring range �.

Protective field and warning field form a pair, the so-called field set. Depending on thevariant used (see section “S300 variants” on page 16), you can define up to four field setsand save these in the safety laser scanner. In this way you can switch the S300 Advancedand S300 Professional safety laser scanners to a different field set in case of a change inthe monitoring situation (see section 3.3.3 “Monitoring cases” on page 20).

You can configure and transfer these field sets to the with the aid of the CDS S300. If thehazardous area to be monitored changes, then you can re-configure the S300 in softwarewithout additional mounting effort.

3.3.3 Monitoring cases

Depending on the variant used (see section “S300 variants” on page 16) up to fourmonitoring cases can be defined and selected during operation using static or dynamiccontrol inputs. In this way, for instance, it is possible to monitor vehicles as a function ofthe velocity.

With the aid of a monitoring case you can define for a field set …

� the field conditions (control signals) for switching to the related field set.

� which multiple sampling is used for the field set.

3.4 Applications

3.4.1 Stationary applications

Hazardous area protection

On stationary machines, the S300 switches the output signal switching devices (OSSDs) tothe OFF state if the protective field is interrupted. The S300 initiates the shutdown of themachine or the shutdown of the dangerous state.

Hazardous area protection with multiple monitored areas (position-related protectivefield switching)

Using the safety laser scanners S300 Advanced and Professional (see chapter 3.2.1“S300 variants” on page 16) you can define various monitoring cases to match theprotective field and warning field to the situation on the machine and to monitor changinghazardous areas — e.g. during different machine production phases — depending on thesituation.

Product description

Point-of-operation guarding

The S300 safety laser scanner can be used to prevent starting or restarting as long asthere are persons in the hazardous area. The machine can only be started or restarted ifthe S300 does not detect any object in the protective field. This is particularly importantfor system interiors that can only be seen with difficulty from the outside, or cannot beseen at all.

In this application the S300 � does not have a stop function. The primary protectivefunction that stops the dangerous movement is provided in the example by a lightcurtain , while the S300 monitors the restarting of the machine.

Hazardous point protection (vertical operation)

The S300 can used be used vertically to trigger stopping of the dangerous movement.Compared to horizontal protection, the area to be protected in front of the machine orsystem can be reduced. Hazardous point protection is necessary if the operator is near thedangerous state of the machine. Hand protection is required to protect the hazardouspoint.

Product description

Access protection (vertical operation)

You can also use the S300 vertically for access protection. Access protection can be usedwhen the access to the machine can be defined by physical means. In the case of accessprotection, the S300 detects the entry of a person, but not presence in the hazardous area(no point-of-operation protection).

3.4.2 Mobile applications

The S300 can be used both on manually controlled vehicles, e.g. fork lift trucks, and alsoon automated guided vehicles (AGV) or trolleys.

You can use the S300 on vehicles, e.g. to protect the route of a vehicle through a factorybuilding. If there is a person or an obstacle in the hazardous area, the S300 ensures thatthe vehicle reduces the velocity and stops if necessary.

Velocity-dependent protective field switching

On the S300 Advanced and Professional you can define several monitoring cases. Thesecases are used to monitor the hazardous areas differently at varying velocities.

On the S300 Professional you can also acquire the velocity of the vehicle usingincremental encoders (see chapter 5.1.5 “Incremental encoder specification” on page 62)and in this way dynamically adapt the different size field sets to the vehicle velocity.

3.5 Configurable functions

3.5.1 Field sets

Configuring the protective field and warning field

With the aid of the CDS you can configure the field set, which comprises a protective fieldand a warning field. During this process you configure the shape and size of the protectivefield and the warning field. You can realise any field shape required.

The area to be monitored is scanned radially by the S300. The S300 cannot see throughobjects during this process. The area behind objects that are in the area to be monitored(pillars, grilles, etc.) can thus not be monitored.

Protective field and warning field can cover up an angle of up to 270° and have differentradial scanning ranges depending on the resolution configured (see Tab. 4 on page 25).

Check the protective fields configured!

Prior to commissioning the machine or vehicle, check the configuration of the protectivefields using the instructions in chapter 8“Commissioning” on page 74 and using thechecklist on page 107.

Protective field or warning field suggested by the safety laser scanner

The CDS can suggest the protective field or warning field. The safety laser scanner scansthe visible room contour several times. From the data obtained the CDS suggests thecontour and size of the field.

In those places at which the room contour is smaller than the maximum protective fieldrange (e.g. at �), the protective field corresponds to the room contour.

The measuring error tolerances for the S300 are automatically subtracted from theprotective field size. As a result the protective field is slightly smaller than the surfacecovered .

In those places where the room contour is larger than the protective field range �, theprotective field corresponds to the possible scanning range (see Tab. 4 on page 25).

Check the protective field suggested!

The protective field suggested by the CDS is not a replacement for the calculation of thesafety distance. Calculate the safety distance based on the description in chapter 4“Mounting” on page 37. Prior to commissioning the application, check the configuration ofthe protective fields using the instructions in chapter 8 “Commissioning” on page 74 andusing the checklist on page 107.

In the CDS field set editor, you can also request a suggestion for the protective field.

3.5.2 Application and resolution

With the aid of the CDS you can configure the S300 for use on a stationary or mobileapplication. Also set the resolution of the S300.

The maximum protective field range depends on the resolution set. The following tableshows the related maximum protective field range at the resolutions that can be set:

Resolution Maximum protective field range

30 mm 1.25 m

40 mm 1.6 m

50 mm 2 m

70 mm 2 m

� The maximum protective field range of the S300 must be sufficient to cover thecalculated protective field size including the necessary supplements (see section 4.1.1“Protective field size” on page 38).

� The warning field can be configured to up to 8 m for all variants and resolutions. Thedetection capability of the warning field is dependent on the remission of the objects tobe detected (see Fig. 64 “Diagram of scanning ranges for various reflectances” onpage 86).

3.5.3 Using the contour as a reference

In addition to the protective field, the S300 can also monitor a contour (e.g. the floor invertical applications or the walls in horizontal applications).

For contour monitoring you define a contour segment �. The contour segment comprisesa positive and a negative � tolerance band.

Product description

The OSSDs on the S300 change to the OFF state if …

� there is an object in the protective field.

� the monitored surrounding contour is no longer in the tolerance band (e.g. if a door isopened or if the position of the S300 is changed).

You can define any number of contour segments. The contour segments must not benarrower than the configured resolution. At the points where a contour has beenconfigured as a reference you cannot define a warning field.

You define the contour as a reference in the CDS field set editor.

Vertical operation

In vertical operation (for access protection and hazardous point protection) according toIEC/ EN 61�4963 you must always configure the used protective fields with the contour asreference function.

Use lateral, vertical boundaries of the opening (e.g. door frame) and the floor as reference.If in this case the position of the S300 is changed in one or more planes, the distance tothe reference changes and the S300 switches its OSSDs to the OFF state.

Horizontal operation

On horizontal operation, you can also use the contour as reference function, e.g. so that ifa door is opened (change to the room contour) the OSSDs on the S300 are placed in theOFF state.

3.5.4 External device monitoring (EDM)

After every interruption to the protective field and prior to restarting the machine, theexternal device monitoring monitors the switching devices operated by the OSSDs (e.g.contactors). In this way the external device monitoring detects whether, e.g. the (positivelyguided) contacts on the contactors connected are in the OFF position.

The machine is only allowed to start if both contactors are in the OFF state, that is they aredeactivated.

The table shows how the S300 reacts if the external device monitoring detects a contactormalfunction:

Without internal restartinterlock

� The system locks completely (lock-out).

� The error message appears in the 7segment display.

With restart interlock � The S300 switches its OSSDs to the OFF state.

� The LED � is illuminated.

� The error message appears in the 7segment display.

You can configure the external device monitoring in the CDS.

� You will find examples on the connection of the external device monitoring in section 6.3“Connection diagrams” on page 69.

� If you do not use the external device monitoring function, leave the inputs disconnected(see section 5.1.1 “Pin assignment on the system plug” on page 61).

3.5.5 Application diagnostic output “Error/contamination”

The S300 has a configurable application diagnostic output. The following configurationfeatures are available in the CDS:

3.5.6 Restart

You can configure the restart behaviour of the S300 as follows:

� without restart interlock

� with restart delay

� with restart interlock

It is imperative that you configure the S300 with restart interlock if the protective fieldcan be left to approach the hazardous point or if a person cannot be detected at everypoint in the hazard area for the S300!

During the assessment, pay attention to whether the protective field can be left in thedirection of the hazardous point, to areas that are unprotected due to the mounting andthe unprotected near range of the S300 (see section 4.5 “Methods of preventingunprotected areas” on page 50).

Configuration of the S300 without restart interlock

After the OSSDs on the S300 have been switched to the OFF state due to an object in theprotective field, the OSSDs are re-enabled again immediately when there is no longer anobject in the active protective field.

This configuration is only allowed …

� if an external restart interlock is realised on the machine controller

or

� if the protective field cannot be left in the direction of the hazardous point and if peoplecan be detected by the S300 at every point in the hazardous area!

Restart delay for mobile applications

In mobile applications you can configure a restart delay from 2 to 60 seconds on theS300. The OSSDs on the S300 change to the ON state if there is no object in theprotective field for the duration given.

This configuration is only allowed if the protective field cannot be left in the direction of thehazardous point and if a person can be detected by the S300 at every point in thehazardous area!

WARNING


S300


Product description

Configuration of the S300 with restart interlock

The OSSDs on the S300 change to the OFF state to trigger a machine � or vehicle stop assoon as there is an object in the protective field . They do not change to the ON state �,even if there is no longer an object in the protective field. The OSSDs only change to theON state if the operator operates the control switch for restart or reset.

Place the control switch for restart or reset in a suitable place!

Place the control switch for restart or reset outside the hazardous area such that it cannotbe operated by a person in the hazardous area. Ensure that the person who operates thecontrol switch has a full view of the hazardous area.

Reset

The reset function is often also called “preparation for restart”. In these operatinginstructions the term reset is used.

If you want to activate the restart interlock on the S300 (internal) and also a restartinterlock on the machine (external), then each restart interlock has its own control switch.

After operating the control switch for the internal restart interlock (with protective fieldunoccupied) …

� the S300 switches its OSSDs to the ON state.

� the LED � on the safety laser scanner illuminates green.

The external restart interlock prevents the machine from restarting. After resetting theS300 the operator must press the control switch to restart the machine controller.

Ensure that the correct sequence is followed!

The controller must be realised such that the machine only restarts if the S300 is firstreset and then the control switch for restarting the machine controller is operated.

� You will find examples on the connection of the internal restart interlock in chapter 6.3“Connection diagrams” on page 69.

� If you do not use the external device monitoring function, leave the inputs disconnected(see section 5.1.1 “Pin assignment on the system plug” on page 61).

You can configure the type of restart in the CDS.

3.5.7 Multiple sampling

If multiple sampling is set, an object must be scanned several times before the S300switches its OSSDs to the OFF state. In this way you can reduce the probability thatwelding sparks, insects or other particles, result in the shutdown of the plant.

If a multiple sampling of 3 is configured, for instance, an object must be detected threetimes in succession before the S300 switches the OSSDs to the OFF state.

The total response time is increased by the multiple sampling!

With a multiple sampling greater than 2, note that you must add a supplement to the basicresponse time (see section 11.2 “OSSD response times” on page 86)!

On the S300, a multiple sampling of 2 is the minimum setting. You can set the multiplesampling to up to 16 with the aid of the CDS.

Recommended multiple sampling Application

2 times Stationary under clean ambient conditions

2 … 4 times Mobile

4 … 8 times Stationary under dusty ambient conditions

Using multiple sampling you can increase the availability of a plant.

You can configure multiple sampling in the CDS. You can set individual multiple samplingfor each monitoring case.

3.5.8 Monitoring cases on the S300 Advanced and Professional

If you use the S300 Advanced, you can define up to two monitoring cases, if you use theS300 Professional, you can define up to four monitoring cases. You allocate a field set toeach monitoring case.

Switching between these monitoring cases during operation is performed using staticcontrol inputs (see section 3.5.10 on page 31) or with incremental encoders usingdynamic control inputs (see section 3.5.11 on page 32).

Ensure that the safety distance to the hazardous point is adequate in any monitoringcase to protect the hazardous area!

See chapter 4 “Mounting” on page 37.

3.5.9 Stand-by mode and park mode

If, in mobile applications, vehicles are not moved for a time, the OSSDs and the laser onthe S300 can be switched off. In this way the power consumption of the device is reduced.

Use this function if, e.g. you use several vehicles and do not move them for a time.

The function can be realised with the aid of the stand-by mode or the park mode.

Stand-by mode

A dedicated STBY single-channel input is provided for switching to the stand-by mode (seesection 5.1.1 “Pin assignment on the system plug” on page 61).

Park mode on the S300 Advanced and S300 Professional

To switch to the park mode, configure a monitoring case for which the park mode isdefined in the CDS. With the aid of the external control, the control inputs must then be setso that this monitoring case is activated.

3.5.10 Static control inputs on the S300 Advanced and Professional

When switching the monitoring cases using static and dynamic control inputs, pleasenote the following points:

�Ensure that the control for the monitoring case switching has the required level of safety.

�Ensure that the circuit for the control inputs is suitable for the ambient conditions to beexpected so that systematic and design-related effects and resulting errors on theswitching of the monitoring cases can be excluded.

�Ensure that the control — using static or dynamic control inputs (incremental encoderinputs) — provides switching between the monitoring cases in the correct time frame.Note that at the time of the switching there may be a person in the protective field. Onlyby means of switching in the correct time frame (i.e. before the hazard occurs at thispoint for the person) is protection provided (see section 4.6 “Time for monitoring caseswitching” on page 52).

S300 Advanced

The S300 Advanced has one dual-channel control input via which the two possiblemonitoring cases can be switched. The control signal must be applied to the connectionsas a complementary signal.

The following table shows the levels that must be present at the connections for thecontrol input to define the logical input state 1 and 0 at the related control input.

S300 Professional

The S300 Professional has two dual-channel control inputs via which the four possiblemonitoring cases can be switched. You can use the two control inputs universally both asstatic control inputs and as dynamic control inputs (for incremental encoders).

If you are using static sampling, decide between complementary or 1ofn samplingdepending on the control features available.

Input delay

The control device that you want to use to switch the control inputs must be able to switchto the defined input condition within 10 ms. If this is not the case (e.g. due to bouncetimes on the switching contacts connected), you can increase the input delay in steps of40 ms.

The following figures, based on experience, give input delays for various methods ofswitching:

3.5.11 Dynamic sampling with incremental encoders on the S300 Professional

With dynamic sampling using incremental encoders, you define for each monitoring casethe number of pulses that must be present at the incremental encoder inputs for therelated velocity.

To detect a fault or the failure of an encoder, two incremental encoders must beconnected. Incremental encoders with 0°/90° outputs are required to be able to detectthe direction of travel.

During the configuration of the monitoring cases in the CDS, you must cover all possible orallowed velocities of the vehicle. If an undefined velocity is reached during operation, thesystem will lock-out continuously. This property can, e.g., also be used for the safemonitoring of the maximum velocity of vehicles.

3.5.12 Control input C on the S300 Professional for mobile applications

If, on the S300 Professional in a mobile application, the inputs A and B are connected toincremental encoders, an additional control input C can be formed using the RESET andRES_REQ connections (see Tab. 13 on page 61).

Using the control input C, it is then possible to switch to a monitoring case that makespossible, for instance, turning on the spot. Complementary sampling is used on the input;the input has priority over the status of the incremental inputs.

3.5.13 Checking the monitoring case switching on the S300Professional

To check the switching between monitoring cases, configure a series of monitoring cases.Here you can define either an arbitrary sequence, a unique sequence, or two alternativesequences.

� Arbitrary sequence: It is allowed to switch from one monitoring case to any other definedmonitoring case.

� Unique sequence: It is only allowed to switch from a monitoring case to anotherspecifically defined monitoring case.

� Alternative sequence: It is allowed to switch from a monitoring case to one of twospecifically defined monitoring cases.

Use the monitoring of the monitoring case switching as an additional check on yourcontrol. For example, in this way deviations from a sequence in the production process ona system could be detected.

A name can be assigned to the application configured and to the laser scanner(s). Thenames are saved in the devices after the configuration is transferred. The name chosenmay be, for example, the identifier for the vehicle, system or the machine.

You enter the application name and the name of the laser scanner used in the CDS.

3.6 S300 in master/slave operationThe S300 Advanced and Professional variants can be integrated into a master/slavesystem using an EFI connection.

� Two S300 can form the master/slave system in which one of the laser scanners is themaster, the other the slave.

� An S300 can be connected to a higher-level device (S3000, series UE100 switchingamplifier or series UE1000 bus node). In this case the S300 is the slave.

When the S300 is switched on in a configured master/slave system, the followingmessage appears briefly on the 7segment display (see section 8.3 on page 77):

� on the S300 master

� On the S300 slave

3.6.1 Addressing the slave

To unambiguously differentiate between the master device and slave device in amaster/slave system, it is possible to define a S300 as a slave. For this purpose a jumperis wired between the connection terminals 13 (ERR) and 7 (A1) (see section 5.1.1 “Pinassignment on the system plug” on page 61).

Connect this connection terminal only for a slave device that is connected to a master overEFI and that as a result uses the master’s control inputs and its application diagnosticoutput.

3.6.2 Control inputs

In a master/slave system, the control signals for monitoring case switching are applied tothe inputs on the master. The slave is connected to the master via EFI and receives fromthe master the input information for monitoring case switching.

You can only connect the input signals to one safety laser scanner. Distributed connectionof the input signals to two safety laser scanners is not possible.

You can configure the control inputs of the master in the CDS.

3.6.3 Internal or external OSSDs

In a master/slave system you define in the CDS which output signal switching device(OSSD) is switched when there is an object in the protective field.

� Internal OSSDsDefines that the protective field or the protective fields switch the OSSDs on S300.

� External OSSDsThe S300 transmits the status of the field sets (protective field/warning field) over theEFI. The OSSDs on another device connected via the EFI have switched.– Connected S300 or S3000: The OSSDs on the second safety laser scanner are

switched.– Switching amplifier (UE100 series) connected: The OSSDs on the UE100 are switched

depending on its configuration.– Bus node (UE1000 series) connected: The information is passed to an FPLC, which

further processes the information, depending on the configuration of the UE1000.

3.6.4 Monitoring case switching

In a master/slave system, the master defines the number of possible monitoring cases. Ifan S300 with a higher level device (S3000, series UE100 switching amplifier or seriesUE1000 bus node) is configured as a slave, more monitoring cases may therefore beavailable depending on the device and its configuration.

A field set and the input conditions that activate the monitoring case must be allocated toeach monitoring case.

The S300 Professional is used on an S3000 Professional as a slave. Eight monitoringcases are configured for the S3000 Professional. On the S300 Professional there are alsoeight monitoring cases available in this situation; the 4 possible laser scanner field setscan be allocated to these monitoring cases.

3.7 Indicators and outputs

3.7.1 LEDs and 7segment display

The LEDs and the 7segment display indicate the operational status of the S300. They areon the front face of the safety laser scanner.

The symbols have the following meaning:

OSSDs in the OFF state (e.g. in case of object in the protective field, monitored contourchanged, reset required, lock-out)

Warning field interrupted (object in warning field)

OSSDs in the ON state (no object in protective field)

Reset required

Optics cover contaminated

3.7.2 Outputs

Using the outputs on the S300 you shutdown the dangerous state on a machine, a plant ora vehicle and evaluate the operational status of the S300. The S300 has the followingoutputs:

� OSSDs

� application diagnostic output “Warning field interrupted”

� application diagnostic output “error/contamination”

� application diagnostic output “Reset required”

The outputs are fed out at the system plug (see section 5.1 “System connection” onpage 60).

All outputs are only allowed to be used for the purpose specified. Note that the signals atthe application diagnostics outputs for “warning field”, “contamination of the opticscover/error” and “reset required” are single-channel and therefore are not allowed to beused for tasks related to safety. For this reason, the warning field on all S300 variants isnot allowed to be used for tasks related to the protection of people.

Mounting

4 MountingThis chapter describes the preparation and completion of the mounting of the S300 safetylaser scanner. Mounting requires four steps:

� definition of the application and the necessary mounting location for the laser scanner

� calculation of the protective field sizes

� definition of the switching point between monitoring cases (only S300 Advanced andS300 Professional)

� mounting the safety laser scanner with or without mounting kits

No protective function without sufficient safety distance!

Only if you configure the protective field such that there is an adequate safety distance tothe hazardous area, is protection by the S300 ensured.

�Mount the S300 in a dry place and protect the device from dirt and damage.

�Avoid the installation of the S300 in the vicinity of strong electric fields. These can, e.g.,be produced by welding cables, induction cables in the immediate vicinity and also bymobile telephones operated nearby.

�Ensure that there are no obstacles in the area to be monitored in the field of view of theS300 that could cause interference or shadowing. Such shadowed areas cannot bemonitored by the S300. If there are unavoidable shadowed areas, check whether thereis a risk. Take additional safety precautions as necessary.

�Keep the area to be monitored free of smoke, fog, steam or other forms of air impurities.There must not be any condensation on the light output window. Otherwise the functionof the S300 may be impaired and incorrect switching may occur.

�Avoid placing highly reflective objects in the scan plane of the S300. Examples:Retroreflectors can affect the measurement results of the S300. Strongly reflectiveobjects within the protective field can blank part of the area to be monitored in certaincircumstances.

�Mount the S300 such that it is not dazzled by incident sunlight. Do not positionstroboscopic and fluorescent lights or other strong light sources directly in the scanplane as these may affect the S300 in specific circumstances.

�Mark the protective field on the floor, if appropriate for the application (seeIEC/EN 61�4961, chapter 7).

�Add the general protective field supplement of 100 mm to each protective field sizecalculated. The maximum protective field range of the S300 must be sufficient to coverthe calculated protective field size and the necessary supplements.

The following steps are necessary after mounting and installation:

� completing the electrical connections (chapter 5 “Electrical installation”)

� configuration of the protective field (chapter7 “Configuration”)

� commissioning and checking of the installation (chapter 8 “Commissioning”)

� checking the function and safe shutdown (section 8.2 “Test notes”)

4.1 Stationary application in horizontal operationThis type of protective device is suitable for machines and systems on which, e.g. ahazardous area is not completely enclosed by a guard.

For a horizontal stationary application determine …

� the protective field size to observe the necessary safety distance.

� the height of the scan plane.

� the restart behaviour.

� measures to protect any areas not covered by the S300.

Once you have defined the protective field size, mark the boundaries of the protective fieldon the floor. In this way you will make the protective field boundaries visible for theoperator and ease subsequent testing of the shape of the protective field.

The protective field must be so configured that a safety distance (S) to the hazardous areais maintained. This safety distance ensures that the hazardous point can only be reachedafter the dangerous state of the machine has been completely stopped.

If you are using an S300 Advanced or S300 Professional, you can define severalmonitoring cases with different protective fields. In such a case you must calculate theprotective field size for all protective fields used.

You can operate the S300 in stationary horizontal operation with 30, 40, 50 or 70 mmresolution. The maximum protective field range for the S300 is given by the resolution.

Ensure that a human leg can be detected with 70 mm resolution!

As per EN 999, mount the scan planes for horizontal stationary applications with 70 mmresolution at least 300 mm above the floor (see “Height of the scan plane at 70 mmresolution” on page 41).

The safety distance S depends on:

� approach speed of the body or parts of the body

� stopping/run-down time of the machine or system(The stopping/run-down time is shown in the machine documentation or must bedetermined by taking a measurement.)

� response time of the S300

How to calculate the safety distance S:

�First, calculate S using the following formula:S = (K × (TM + TS)) + ZG + ZR + C

Where …

K = Approach speed (1600 mm/s, defined in EN 999)TM = Stopping/run-down time of the machine or systemTS = Response time of the S300 and the downstream controllerZG = General safety supplement of the S300 = 100 mmZR = Supplement for measurement error related to reflectionC = Supplement for prevention of reaching over

The response time TS of the S300 depends on …

� the basic response time of the S300.

� the multiple sampling set.

� the transmission speed from external inputs and to external OSSDs via EFI.

See section 11.2 “OSSD response times” on page 86.

Supplement ZR for measurement error related to reflection

Avoid mounting retroreflectors at a distance of less than one meter from the boundaryof the protective field!

With retroreflectors positioned at a distance of less than 1 m from the boundary of theprotective field a supplement, ZR, of 200 mm must be added to the protective field.

Supplement C for protection against reaching over

With a protective field installed horizontally, there is a risk that people may reach over theprotective field and in this way reach the hazardous area before the S300 shuts down thedangerous state. For this reason the calculation of the safety distance must take intoaccount a supplement to prevent persons from finding themselves in a hazardoussituation by reaching over (see EN 294, table 1) before the S300 triggers.

The necessary supplement for the safety distance is dependent on the height of the scanplane for the protective field. At low heights � the supplement is larger than at greaterheights and �.

In summary there are three usual variations of mounting the scan plane for the S300. Theoptimal variation depends on the related application. Tab. 12 provides assistance makingthe selection.

In case of scan planes at a height of more than 300 mm ensure that people cannotreach the hazardous area by crawling underneath the scan plane!

If you mount the protective device higher than 300 mm, you must prevent crawlingbeneath by means of additional measures. For applications that are accessible to thepublic, the mounting height may need to be reduced to 200 mm (on this subject see theappropriate regulations).

How to calculate the supplement C:

� If the safety distance is to be kept as small as possible, calculate C using the followingformula:C = 1200 mm – (0.4 × HD)Here HD is the height at which the protective field is mounted.

The minimum supplement C to prevent reaching over is 850 mm (arm length).

Height of the scan plane at 70 mm resolution

Due to the radial sampling of the protective field, the optical resolution will be lower thefurther away you get from the safety laser scanner.

If you choose a resolution of 70 mm in the CDS for hazardous area protection, a humanleg may, in certain circumstances, not be detected (e.g. scan to left and right of thebone �).

If you mount the S300 higher, the scan plane is at fibula height and the leg is alsodetected with an object resolution of 70 mm .

4.2 Stationary vertical operation for access protectionAccess protection can be used when the access to the machine can be defined by physicalmeans. For access protection the S300 detects the entry of an entire body.

� To ensure adequate access protection, a response time of ≤ 90 ms and a resolution of70 mm or finer are required.

� To protect the protective device against unadvertent adjustment or manipulation, youmust use the contour of the surroundings as a reference for the S300 (see section 3.5.3“Using the contour as a reference” on page 25).

4.2.1 Safety distance

For access protection, a safety distance (S) must be maintained between protective fieldand hazardous area. This safety distance ensures that the hazardous point can only bereached after the dangerous state of the machine has been completely stopped.

The safety distance S as defined in EN 999 and EN 294 depends on:

� reach or approach speed

� stopping/run-down time of the machine or system(The stopping/run-down time is shown in the machine documentation or must bedetermined by taking a measurement. On request SICK service can perform a detailedstopping/run-down measurement on your plant.)

The total response time of the S300 must not be more than 80 ms for accessprotection!

If a critical response time is exceeded (for an object diameter of 70 mm and a speed of1.6 m/s that is 90 ms) a person may no longer be detected under certain circumstances.

In specific cases agreed with the responsible authorities higher response times may beallowed (for example by increasing the detection time available by positioning the scannerat an angle). In this case ensure that the areas the laser scanner cannot see are protectedby additional measures.

4.3 Stationary vertical operation for hazardous pointprotection

Hazardous point protection is necessary if the operator must remain near the dangerousstate of the machine. Hand protection is required for hazardous point protection.

The S300 must therefore be configured with a resolution of at least 40 mm.

Never use the S300 for safety applications in which finger protection is required!

Due to the finest possible resolution of 30 mm, the S300 is not suitable for fingerprotection.

To protect the protective device against unadvertent adjustment or manipulation, youmust use the contour of the surroundings as a reference for the S300 (see section 3.5.3“Using the contour as a reference” on page 25).

4.3.1 Safety distance

For hazardous point protection, a safety distance must be observed between protectivefield and hazardous point. This safety distance ensures that the hazardous point can onlybe reached after the dangerous state of the machine has been completely stopped.

Prevent reaching around or reaching behind the protective field!

Always mount the laser scanner such that reaching around and behind is impossible.Provide suitable additional precautions as necessary.

The safety distance S as defined in EN 999 and EN 294 depends on:

� stopping/run-down time of the machine or system(The stopping/run-down time is shown in the machine documentation or must bedetermined by taking a measurement.)

� If the result S is > 500 mm, you may be able to reduce the safety distance using thefollowing calculation:S = 1600 × (TM + TS) + 8 × (d – 14 mm) [mm]

� If the new value S is > 500 mm, then use the newly calculated value as the minimumsafety distance.

� If the new value S is ≤ 500 mm, then use 500 mm as the minimum safety distance.







4.4 Mobile applicationsIf the dangerous state is produced by a vehicle (e.g. AGV or fork lift), the hazardous areathat is produced by the movement of the vehicle is protected by the S300.

� The S300 may only be used to protect vehicles powered by electric motor.

� In the following calculations only take into account the velocity of the vehicle, not thespeed of the person walking. This is based on the assumption that the person willrecognize the danger and stand still.

� For vehicle protection, observe DIN/EN 1525 “Safety of industrial trucks. Driverlesstrucks and their systems”.

� If the application is to protect vehicles from collisions, then you may need to usedifferent assumptions.

For a horizontally mounted mobile application, determine:

� protective field length

� protective field width

� height of the scan plane

� restart behaviour

� methods of preventing unprotected areas

4.4.1 Protective field length

You must configure the protective field such that a safety distance to the vehicle ismaintained. This ensures that a vehicle monitored by the S300 comes to a stop before aperson or object is reached.

If you are using an S300 Advanced or Professional, you can define several monitoringcases with different protective fields. You can switch these using static control inputs or onthe S300 Professional also dynamically.

For dynamic switching, the vehicle velocity is determined by means of incrementalencoders connected to the S300 Professional. The protective fields can therefore beswitched in the S300 Professional dependent on velocity. In such an application, theprotective field sizes (in particular the protective field length) must be calculated for allvelocities.

How to calculate the protective field length SL:

�Calculate the necessary protective field length SL using the formula:SL = SA + ZG + ZR + ZF + ZB

Where …

SA = Stopping distanceZG = General safety supplement of the S300 = 100 mmZR = Supplement for any measurement error of the S300 related to reflectionZF = Supplement for any lack of ground clearance of the vehicleZB = Supplement for the reduction in the braking performance of the vehicle to be found

in the related vehicle documentation

Stopping distance SA

The stopping distance comprises the braking distance for the vehicle, the distance coveredduring the response time of the safety laser scanner and the response time of the vehiclecontroller.

Take into account that the braking distance for a vehicle is not linear with increasingvelocity, but increases in a square function. This is particularly important if you switchbetween protective fields with different sizes a function of the velocity using incrementalencoders.

Supplement ZF due to lack of ground clearance

This supplement is necessary because a person is generally detected above the foot andthe braking action can therefore not take into account the length of the foot in front of thedetection point. If a vehicle has no ground clearance, a person may receive foot injuries.

Mounting

With two S300 mounted at an angle of 45° on the front corners of a vehicle, you canconfigure the protective fields so that there are no unprotected areas and the hazardousareas in narrow aisles can also be protected.

With two S300 mounted diagonally opposite, you can implement protective fields on thevehicle for all-round protection in all directions of travel.

4.5.1 Near range

Make the near range impassible using a bar or a recess, or additionally protect the nearrange (5 cm wide area in front of the optics cover) using a proximity switch with 5 cmacquisition range. The vehicle may then be accelerated as required.

4.6 Time for monitoring case switchingIf you switch between several monitoring cases, along with the safety distance to thedangerous state there is a further safety relevant aspect that you must address.

If you switch the control within 10 ms, the protective field selected is available within thebasic response time of the S300. For this reason you can initiate the switching at the timeat which you actually want to switch from one monitoring case to the other.

However, you must advance the timing of the switching if you …

� have entered an input delay for your switching method (see section “Input delay” onpage 32).

� use external inputs (e.g. the inputs on another S300).

� control external OSSDs instead of the internal OSSDs (e.g. the OSSDs on another S300)via EFI.

The following diagram shows the relationships:

� If the input conditions are present at the control inputs within 10 ms (cf. �), the timingfor the switching (tUF) does not need to be advanced.

� If an input delay for the control inputs needs to be taken into account (cf. ), the timingfor the switching (tUFVz2) must be advanced by the input delay.

� If the inputs of a different device are used via EFI, the timing for the switching (tUFVz3)must be further advanced by 40 ms (cf. �).

� If external OSSDs are used, the timing for the switching (tUFVz4) must be further advancedby 20 ms (cf. �).

Set the timing for the switching such that the S300 already detects a person in theprotective field with an adequate safety distance before the dangerous state occurs!

Note that at the time of the switching there may be a person in the protective field. Only bymeans of switching in the correct time frame (i.e. before the hazard occurs at this point forthe person) is protection provided.

� In the phases before and after the switching, the safety distances calculated for theindividual monitoring cases apply on their own.

� The considerations above serve only for the selection of the optimal timing of theswitching.

� If the timing for the switching cannot be exactly defined, e.g. due to the variableprocessing speed of the machine, or advancing the timing results in prematuretermination of the monitoring of the initial area, you must allow the two protective fieldsto partially overlap.

� For the movement to the left, that is for the switching to the monitoring case �, thesame applies.

� The protective fields for the monitoring cases must overlap here �, so that a protectivefunction is always provided.

How far you must advance the timing for the switching depends on …

� whether you use external OSSDs via EFI.

� whether you use external control inputs (e.g. on another S300).

How to calculate the timing for the switching:

�Calculate the timing for the switching using the following formula:

tUFVz = tEVz + texOVz + tStVz

Where …

tUFVz = Timing advance for the switching

tEVz = Input delay for the control inputs

texOVz = Delay due to external OSSDs over EFI = 20 ms

tStVz = Delay due to external control inputs over EFI = 40 ms

Special features to note during mounting:

�Mount the S300 such that it is protected from moisture, dirt and damage.

�Ensure that the entire field of view of the S300 is not restricted.

�Mount the laser scanner such that the indicators are easy to see.

�Always mount the S300 so that there is still enough space for mounting and removingthe system plug.

�Avoid excessive shock and vibration loading on the safety laser scanner.

�On applications that suffer from heavy vibration, prevent the fixing screws from comingloose using screw locking devices.

�Regularly check the tightness of the fixing screws.

�Prevent personnel from being able to crawl beneath, stand behind or climb over theprotective field by means of appropriate mounting of the S300.

The origin of the scan plane is 116 mm above the bottom edge of the S300 (seesection 11.5.3 “Scan plane origin” on page 101).

There are three possible ways of fixing the S300:

� direct mounting without mounting kit

� mounting with mounting kit 1a or 1b

� mounting with mounting kit 2 (only in conjunction with mounting kit 1a or 1b)

You will find the part numbers for the mounting kits in section 12.3.1 “Mounting kits” onpage 102.

If you connect devices together using EFI, connect EFIA on the first device to EFIA on thesecond device and EFIB on the first device to EFIB on the second device. Use the sameearthing concept for the devices.

5.1.5 Incremental encoder specification

Both incremental encoders must meet the following specifications:

� two-channel rotary encoder with 90° phase offset

� supply voltage: 24 V DC

� outputs: push/pull outputs

� enclosure rating IP 54 or better

� screened cable

� max. pulse frequency: 100 kHz

� min. number of pulses: 50 pulses per cm

You can procure suitable incremental encoders from SICK AG, tel.: +49 211/5301250 orat www.sick.com. Or contact your local SICK representative.

Never supply both incremental encoders using one supply cable!

� The connecting cables for both incremental encoders must be in separate sheaths.

� The power supply to the two incremental encoders must be independent. For thispurpose use the connection terminals provided, 19 and 20 as well as 21 and 22.

5.2 System plug assemblyThe system plug has holes for cable glands on the underside and on the rear. The numberof cable glands and fittings varies depending on the variant:

� system plug SX0B-A0000G for S300 Standard and S300 Advanced:– 1 cable gland with M16 cable gland– 1 cable gland without M16 cable gland (blanking plug)

– 2 cable glands without M12 cable gland (blanking plugs)– 1 M12 cable gland, enclosed loose

� system plug SX0B-A0000J for S300 Professional:– 1 cable gland with M16 cable gland– 1 cable gland without M16 cable gland (blanking plug)

– 6 cable glands without M12 cable gland (blanking plugs)– 2 M12 cable glands, enclosed loose

You can also procure the S300 with pre-assembled system plug with varying cable lengths(see section 5.3 “Pre-assembled system plugs” on page 64 and section 12.3.2 “Systemplug” on page 103).

The length of the spare cable should be such that the system plug cannot inadvertentlybe plugged into a neighbouring S300!

From experience 20 to 30 cm spare cable at the laser scanner have proven to adequate.In this way you avoid the inadvertent connection of the system plug to a neighbouringS300 and operation of an S300 with an incorrect configuration. The spare cable enablesyou to change the S300 with ease if necessary.

Depending on the application use suitable cable glands on the bottom or rear. For the EFIcables you must choose EMC-proof cable glands.

Application examples andconnection diagrams

6 Application examples and connection diagramsThe examples shown are only provided as an aid for your planning. You may need toconsider additional protection measures for your application.

In the examples with protective field switching, note that at the time of the switching theremay already be a person in the protective field. Only by means of switching in the correcttime frame (i.e. before the danger occurs at this point) is reliable protection provided (seesection 4.6 “Time for monitoring case switching” on page 52).

6.1 Stationary applications

6.1.1 Applications with one monitored area (S300 Standard)

The area is permanently monitored by the S300.

The access is monitored permanently. For safety against manipulation on the S300, e.g.the floor is used as a reference. If the alignment of the S300 changes (e.g. due to changesto the bracket), the S300 switches its OSSDs to the OFF state.

6.1.2 Applications with multiple monitored areas (S300 Advanced)

The two areas to be monitored are switched using the static control inputs depending onthe phase of the process on the machine. For example the area � or the area can bemonitored.

6.2 Mobile applications

6.2.1 Vehicle monitoring for unidirectional travel (S300 Standard)

The S300 monitors the area in the direction of travel and switches its OSSDs to the OFFstate to stop the vehicle as soon as there is an object in the protective field.

6.2.2 Velocity-dependent vehicle monitoring for unidirectional travel(S300 Professional)

Using incremental encoders the S300 Professional acquires the velocity of the vehicle viaits dynamic control inputs. For different velocities, various field sets with protective fieldsand warning fields of varying sizes are configured in the S300. The field sets are switcheddynamically using the vehicle velocity.

6.2.3 Velocity-dependent vehicle monitoring for bi-directional travel(2 × S300 Professional in master/slave operation)

Using incremental encoders the master acquires the velocity and the direction of thevehicle via its dynamic control inputs. Various field sets of different sizes are configured inthe S300 for the different velocities. The field sets are switched dynamically using thevehicle velocity.

The slave receives the incremental encoder values from the master over the EFI interface.It monitors the areas for the second direction of travel as a function of the velocity. Assoon as there is an object in the protective field, it switches the OSSDs on the master tothe OFF state over the EFI interface.

Commissioning

8 Commissioning

8.1 Initial commissioning

Commissioning requires a thorough check by qualified personnel!

Before you operate a system protected by the S300 safety laser scanner for the first time,make sure that the system is first checked and released by qualified personnel. The resultof the test must be documented. Please read the notes in chapter 2 “On safety” onpage 10.

�Prior to releasing the machine, check whether the access to the hazardous area or thehazardous point is completely monitored by the protective devices. Following approval ofthe machine also check at regular intervals (e.g. in the morning at the start of work)whether the S300 correctly switches the OSSDs to the OFF state as soon as there is anobject in the protective field. This test should be performed along all protective fieldboundaries as per the specific regulations for the application (see section 8.2 “Testnotes” on page 75).

8.1.1 Power up sequence

After power up the S300 runs through a power up cycle. During the power up cycle, the7segment display indicates the device status.

8.2 Test notes

8.2.1 Pre-commissioning tests

The purpose of the pre-commissioning tests is to confirm the safety requirementsspecified in the national/international rules and regulations (EC Conformity). This appliesparticularly to the safety requirements in the machine directive or work equipmentdirective.

Ensure that you do not place anybody at risk during initial commissioning of themachine!

Always expect that the machine, plant or the protective device does not yet behave as youhave planned.

�Ensure that there are no persons in the hazardous area during initial commissioning.

�Check the effectiveness of the protective device mounted to the machine, using allselectable operating modes as specified in the checklist in the annex (see section 13.2“Manufacturer’s checklist” on page 107).

�Make sure that the operating personnel of the machine protected by the safety laserscanner are properly instructed by specialist personnel before being allowed to operatethe machine. Instructing the operating personnel is the responsibility of the machineowner.

�Ensure that the information label Important information, which is included with thelaser scanner on delivery, is affixed to the machine in a place where it is clearly visiblefor the operators. Ensure that the operators have the possibility to perform this dailycheck correctly.

� The annex to this document includes a checklist for review by the manufacturer andOEM. Use this checklist as a reference before commissioning the system for the firsttime (see section 13.2 “Manufacturer’s checklist” on page 107).

�Document the adjustment of the scanner and the results of the testing during initialcommissioning in a traceable manner. For this purpose also print out the completeconfiguration of the scanner (including protective field shapes) and include these withthe documentation.

Your SICK subsidiary will be pleased to provide you with advice on initial commissioning.

Commissioning

8.2.2 Regular inspection of the protective device by qualified personnel

�Check the system following the inspection intervals specified in the national rules andregulations. This procedure ensures that any changes on the machine or manipulationsof the protective device after the first commissioning are detected.

� If major changes have been made to the machine or the protective device, or if thesafety laser scanner has been modified or repaired, check the plant again as per thechecklist in the annex (see section 13.2 “Manufacturer’s checklist” on page 107).

8.2.3 Daily testing of the protective device by a specialist or authorised personnel

The effectiveness of the protective device must be checked daily by a specialist or byauthorised personnel. The test must also be performed if the operating mode is changed.

No further operation if errors occur during the test!

If any one of the following points is not met, it is not permitted to continue to work on themachine or operate the vehicle. In this case the installation of the S300 must be checkedby specialised personnel (see section 8.2.2 “Regular inspection of the protective device byqualified personnel” on page 76).

� The test must be carried out for the relevant preset monitoring case.

�Check the mechanical installation to ensure that all mounting screws are secure andthat the is properly aligned S300.

�Check each S300 device for visible changes such as damage, manipulation etc.

�Switch on the machine/plant.

�Watch the LEDs on each S300.

� If not at least one LED of each S300 is permanently lit when the machine/plant isswitched on, it is to be assumed that there is a fault in the machine or plant. In this casethe machine must be shut down immediately and checked by a specialist.

�Deliberately obstruct the protective field without risk to any personnel while the machineis running in order to test the effectiveness of the entire system. The LEDs of the S300device must change from green to red and the dangerous movement must stopimmediately. If the S300, with the protective field that you are interrupting, switches theOSSDs on another device (see 3.6.3 “Internal or external OSSDs” on page 35), then onthis device the LEDs must change from green to red and the dangerous movement onthe machine or system connected must come to an immediate stop.

Repeat this test at different points in the danger area and on all S300 devices . If youdiscover any non-conformance of this function, the machine/plant must be shut downimmediately and checked by a specialist.

�For stationary applications, check that the danger area marked out on the floor matchesthe shape of the protective field stored in the S300 and that any gaps are protected byadditional safety measures. In the case of mobile applications, check that the movingvehicle actually stops in a timely manner at the protective field boundaries which are setin the S300 and listed on the information label on the vehicle or in the configurationprotocol. If you discover any non-conformance of this function, themachine/plant/vehicle must be stopped immediately and checked by a specialist.

Care and maintenance

9 Care and maintenance

Do not make any repairs to the device!

The S300 does not contain any repairable components. For this reason do not open theS300 components and only replace the parts that are described in the following chaptersas replaceable.

Switch the entire machine/system off line!

The system could inadvertently start up while you are replacing the optics cover. As amatter of principle, always isolate the machine from the power supply during all work onthe machine and safety laser scanner.

9.1 Cleaning optics coverThe S300 safety laser scanner is largely maintenance-free. The optics cover on the safetylaser scanner should however be cleaned regularly and if it is contaminated.

�Do not use aggressive detergents.

�Do not use abrasive cleaning agents.

Static charges cause dust particles to be attracted to the optics cover. You can diminishthis effect by using the anti-static plastic cleaner (SICK Part No. 5600006) and the SICKlens cloth (Part No 4003353) (see section 12.3 “Accessories/spare parts” on page 102).

How to clean the optics cover:

�Use a clean and soft brush to remove dust from the optics cover.

�Now wipe the window for light output on the optics cover with a clean and damp cloth.

9.2 Replacing optics cover

Perform an optics cover calibration with the aid of the CDS after the replacement of theoptics cover!

The level of contamination is measured continuously during the operation of the S300. Forthis purpose the optics cover calibration must first be performed; this then serves as areference for the contamination measurement (status = not contaminated).The optics cover calibration is only allowed to be performed with a new optics cover! Thenew optics cover must be free of contamination at the time of the optics cover calibration.The optics cover calibration should be performed at room temperature (1030 °C)!

If the optics cover is scratched or damaged, you must replace the optics cover. Order thereplacement optics cover from SICK (see section 12.3 “Accessories/spare parts” onpage 102).

� The optics cover on the S300 is an optical part that must not be soiled or scratched onreplacement.

� The optics cover is only allowed to be replaced by specialist personnel in a dust and dirt-free environment.

� Never replace the optics cover during ongoing operation, as internal parts may beirreparably damaged in certain circumstances and dust particles may enter the device.

� It is imperative that you avoid contamination of the inside, e.g. with fingerprints.

Care and maintenance

� Do not use any additional sealant for sealing the optics cover, e.g. silicon, as thesesubstances may affect the optics.

� Mount the optics cover as per the following instructions to ensure that the housing issealed to IP 65.

This is how you replace the optics cover:

� Only use a new optics cover (see 12.3.10 on page 105).

� When replacing the optics cover, take ESD protection measures.

� Set a torque wrench to 1.2 Nm (hand-tight) and have this at hand.

�Disconnect the system plug and remove the S300.

� Take the S300 to a clean place (office, repair shop or similar).

�First clean the outside of the S300. This prevents foreign bodies entering the devicewhen it is opened.

�Undo the fixing screws � to � for the optics cover.

� Then remove the optics cover.

�Check whether the mirror on the motor is clean and remove any contamination with anoptic brush.

� Take the new optics cover out of the packaging and remove the protection for the seal.

�Remove any remnants of packaging.

�Place the optics cover on the laser scanner and fit the new fixing screws � to �.

�When fitting the new cover, ensure the arrow on the top of the cover points to the frontand that the optics cover is fully in contact without a gap.

� Then tighten the front screws with the torque set.

�Make sure the optics cover is free of dirt and that it is not damaged.

� Then perform an optics cover calibration with the aid of the CDS.

Re-commissioning the S300:

�Correctly re-mount the S300 (see chapter 4 “Mounting” on page 37).

�Connect the S300 system plug.After power up the S300 automatically reads the saved configuration from the systemplug (see section 8.3 “Re-commissioning” on page 77).

Multiple sampling

On the S300 at least double multiple sampling is always set. For a multiple sampling of 3or higher you must add a supplement of 80 ms to the basic response time.

Multiple sampling Supplement Basic response time + supplement

2 times (basic setting) 0 ms 80 ms

3 times 40 ms 120 ms














External OSSDs

If you use the OSSDs on another device via the EFI as external output signal switchingdevices (for example with two S300 connected together), the response time increases by20 ms in each case.

External control inputs

If you use the inputs on another device via EFI as external control inputs (for example withtwo S300 connected together), the response time increases by 40 ms in each case.

Tab. 24: Supplements formultiple sampling

11.3 Timing behaviour of the OSSDsThe S300 tests the OSSDs immediately after switch on and then at regular intervals. Forthis purpose the S300 briefly switches off both OSSDs (for 300 µs) and checks whetherthe OSSDs switch to the OFF state during this time.

Ensure that the safety inputs on the controller used do not respond to these test pulsesand as a result cause the machine or system to unintentionally shutdown!

Approx. 35 ms after the switch on of the OSSDs, the S300 performs the first voltage test �and then after a half basic response time (40 ms) performs a second voltage test �.

After a further half basic response time of the S300 there is a shut-down test , 120 mslater a further voltage test �. Then the S300 performs a shut-down test and a voltage testalternately at an interval of 120 ms. Fig. 66, Fig. 67 and Fig. 68 show the pulse durationsfor the individual tests.

15) Applies to the voltage range between Vs and 0 V.16) Switching currents up to 500 mA are allowed briefly (≤100 ms).17) In the case of a fault (0-V cable open circuit) maximally the leakage current flows in the OSSD cable. The

downstream controller must detect this status as LOW. A FPLC (fail-safe programmable logic controller) mustbe able to identify this status.

18) Make sure to limit the individual line core resistance to the downstream controller to this value to ensure thata cross-circuit between the outputs is safely detected. (Also note EN 60�2041.)

19) When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers, makesure that the test pulses do not result in deactivation.

S300


Annex

13.3 GlossaryActive opto-electronic protective device responsive to diffuse reflection = active opto-electronic protective device responsive to diffuse reflection (e.g. S300, see alsoIEC 61�4963)

The monitoring cases are switched using the control inputs. The S300 Advanced has onestatic control input, the S300 Professional two universal control inputs. The universalcontrol inputs can be used both statically and dynamically (for incremental encoders).

Enhanced function interface = safe SICK device communication

(External device monitoring) A device that electronically monitors the relay or contactoroperated by the protective device prior to each new start.

Protective field and warning field form a pair, the so-called field set.

A component that produces electrical pulses in proportion to a movement. For thesepulses, various physical parameters can be derived, e.g. velocity, direction of travel, etc.

Two S300 that are configured to form a master/slave system using an EFI connection withthe aid of the CDS. The control signals for monitoring case switching are applied to theinputs on the master. The slave is connected to the master via EFI and receives from themaster the input information for local monitoring case switching.

A field set is allocated to a monitoring case. Monitoring case switching is performed usingthe control inputs. In this way the S300 can be adapted to the operating mode of themachine or plant that it monitors.

Plastic part with window for light output. The optics cover is available as a spare part.

(Output signal switching device) The OSSD output is the switching output on the S300.This is a semiconductor output and is periodically tested for correct function. The S300has two OSSD outputs that operate in parallel; for safety reasons these must be evaluatedusing two channels.

The protective field secures the hazardous area on a machine or vehicle. As soon as thesafety laser scanner detects an object in the protective field, it switches the OSSDs to theOFF state and thus initiates the shutdown of the machine or stop of the vehicle.

Reflection of luminance. A measure of the reflectivity is the reflectance defined as the ratioof the luminance reflected from a surface in the measuring direction and the luminance ofa completely matt white surface (white standard).

The minimum size of an object that is acquired by the protective device and is guaranteedby the manufacturer.

The restart interlock is a protective device. In certain situations it prevents the machinefrom automatically restarting. This applies, e.g., after the scanner function has triggeredduring a dangerous machine state, after a change to the operating mode or the method ofactivation of the machine, or after the change to the start control device on the machine.

Contains the configuration memory and all electrical connections. In this way the S300 canbe easily replaced. After re-commissioning the configuration is read from the system plug;the S300 is then, normally, ready for use.

The warning field is a field with a radius of up to 8 m (see section 11.1 “Characteristics” onpage 86). Using this field larger areas can be controlled and simple switching functions(e.g. warning functions) triggered. The warning field is not allowed to be used for tasksrelated to personnel protection.
