SAFETY INFORMATION 2


3 Product description

3.1 Application description

The Safeguard Detector Core application package is used on machines with materialtransportation systems, such as a carton magazine on a packaging machine, to preventthe risk of people getting injured by the empty material transportation system in theevent of interrupting the machine.

The transportation opening to a packaging machine is monitored by at least two sen‐sors. If there is carton in the magazine, an interruption is not possible because thematerial acts like a physical guard. The same principle applies in other plants for otherobjects acting as a physical guard (e.g., transport containers).

Figure 1: Material in the detection zone: carton magazine sufficiently filled

If the magazine is not sufficiently filled or is empty, a person can interrupt the machine.This represents a dangerous state. The task of the Safeguard Detector applicationpackage is to prevent this case by reacting in a safety-related manner and switching offthe system.

Figure 2: No material or too little material in the detection zone: carton magazine not sufficientlyfilled

Limits of the system

The figure below shows the limits of the Safeguard Detector application package. Thesystem considered ends at the outputs of the SICK safety controller. Furthermore, theuser is solely responsible for the safe design of the entire system.

3 PRODUCT DESCRIPTION


Figure 3: Block diagram of the safety chain and limits of the system

The Safeguard Detector application package represents the part of the safety chainthat combines the sensors and safety controller. This combination carries out a sub-safety function. The safety chain can be expanded with additional logic elements(e.g., a higher-level control).

3.2 Safety function

The sensors are evaluated by means of a SICK safety controller. If the system detectsthat the machine opening is not sufficiently covered by suitable objects, meaning thatan interruption or access to the hazardous point is not reliably prevented, the accord‐ingly configured outputs of the safety controller are switched off.

The objects to be detected act as physical guards. They must be selected such that theycarry out their separating function sufficiently and reliably.

The separating function must also be effective during the lapsing of the safety functionresponse time (e.g., while hazardous system movements are stopping after the safetyfunction has been triggered).

DANGERThe technical process parameters must be set to ensure that so many objects are inthe infeed so that they still function as physical guards after the system is switched offby the application package.This means that the application package must switch off the system before the neces‐sary number of objects in the infeed for maintaining protection is undercut. Otherwise,this would mean that the user is at risk.

3.3 Safe state

In the safe state, the accordingly configured safe outputs are in the off state. Themachine is and remains switched off. The safe state is initiated in the following cases:

• No object is detected in the protective field in the time in which the sensors arebeing evaluated; the output of at least one sensor is therefore in the off state.

• The connection between at least one sensor and the SICK safety controller hasbeen interrupted.

• The power supply of at least one sensor and/or the SICK safety controller hasbeen interrupted.

• An error is diagnosed in at least one sensor.

PRODUCT DESCRIPTION 3


• The safety controller receives implausible output signals from the two sensorsbeyond the duration of the configured maximum discrepancy time.

• An internal error has occurred in the SICK safety controller or in one of its compo‐nents.

3.4 System components

The Safeguard Detector application package consists of the following components:

• A sensor package consisting of two identical MultiPulse photoelectric proximitysensors (2x2 or 2x10 Hz).

• A SICK safety controller

For product packages and accessories that can be ordered, see "Ordering information",page 33.see "Ordering information", page 33.

Sensor technology

The sensor part of the system consists of two sensors, both of which are able to triggerthe safety function. As a result of this dual-channel structure (“1 out of 2”), the systemand sensor are single-failure-proof.

Two sensor variants with various pulse rates and response times are available.

NOTICE

• The permissible sensor variants for the Safeguard Detector application packagecannot be configured. The customer is responsible for selecting the correct variantand testing it during the validation.

• Which sensor variant is suitable depends on the logic execution time of the safetycontroller, among other things, see "General sensor data", page 31.see "Generalsensor data", page 31.

• Only sensor variants listed here may be used.• Only sensor pairs with the same pulse rate may be used. A 2 Hz sensor may not be

combined with a 10 Hz sensor.

PRODUCT DESCRIPTION 3


4 Project planning

This chapter includes important information about the proper integration of the Safe‐guard Detector application package for planners, developers, and designers.

4.1 Security

DANGERDangerous state of the machine

b Make sure that the dangerous state of the machine is and remains switched offduring mounting, electrical installation, and commissioning.

b Make sure that the safety controller outputs do not affect the machine duringmounting, electrical installation, and commissioning.

DANGERHazard due to lack of effectiveness of the protective deviceIf insufficiently mounted or subjected to excessive vibrations, the sensors may becomedetached or damaged.It is possible for people to interrupt the hazardous area when the machine is running.

b Where necessary, take suitable vibration reduction measures.

DANGERThe path of the beam between the sensor and the object being detected must alwaysbe kept free and must not be disrupted or manipulated by any other objects.

4.2 Prerequisites

Structural prerequisites

The system only detects the surfaces of objects and not intervention by a person intothe hazardous area of the machine. For this reason, ensure that the detected objectcovers the hazardous area in a manner that sufficiently prevents access or interruption.

The distance between the object (e.g., carton blanks) and the machine must not be sobig that an interruption by a person is possible or else there may still be a hazarddespite an object having been detected (which is the movable physical guard).

If the object moves to the side in the magazine, an interruption opening may be cre‐ated, which, in some circumstances, may not be detected by the sensors. Correspond‐ing countermeasures must be taken by the machine user.

Optical properties of objects

DANGERTransparent objects (film packing , bottles, etc.) may cause availability problems as aresult of their direction-changing effect on light and may lead to safety-relevant incor‐rect switching. For this reason, such objects must be kept out of the sensing range ofthe sensors.

The objects to be detected must have the following properties:• The remission of the objects must be between 6 % and 90 % of a diffusely scatter‐

ing nature. This corresponds to black to white carton surfaces.• Very dark and retroreflective or shiny objects may cause availability problems.

4 PROJECT PLANNING


4.3 Setup location

Positioning the sensors

It must be ensured that enough objects are in the magazine to effectively prevent inter‐vention.

The sensors must be positioned so that they trigger the safety function before therespective quantity of objects is undercut.

4.4 Response time

When configuring the machine, the response time of the entire system must be takeninto consideration. If interruption is possible when a magazine is empty, the stoppingtime of the system must be calculated and the distances to the hazardous points nec‐essary based on this must be complied with.

When calculating the total response time, the following possible influences must betaken into consideration:• Sensor response time• Safety controller response time• Signal transit time between OSSD and actuator• Actuator stopping/run-down time

4.5 Integrating into the electrical control

DANGERIf there is a foreign object in the sensor detection zone, this is not detected as an errorduring normal operation. The same applies if the sensor becomes detached from itsposition due to a mounting error and therefore constantly detects a foreign object, suchas the floor. An error of this kind is discovered by a plausibility check.

b The logic program must check the plausibility of the sensor signals by evaluatingthe discrepancy time, for examplesee "Application logic", page 22.

Restart interlock and reset

The sensors cannot differentiate between an object in the magazine and body parts. Ifit is possible that a person could interrupt the hazardous area and therefore cancel outthe safe state, a restart interlock is required.

In this, the result of the series-connected frequency monitoringand the tolerant dual-channelevaluation function blocks is sufficient as the condition for a restart.

The user is responsible for deciding whether or not a restart interlock is required.

Cross-circuit detection

The dual-channel integration of the sensors requires a detection or the prevention ofcross-circuits between the cables of the sensors to the SICK safety controller. This twosensors must have separate power supplies and cabling in different rooms.

To protect the sensors from overvoltage, the sensors must be supplied with power viathe Flexi Soft safety controller, see "Wiring notes", page 20.

A corresponding configuration must be carried out in the SICK safety controller logicprogram.

4.6 Testing plan

Various tests are required for the Safeguard Detector to function correctly:

PROJECT PLANNING 4


• A thorough check must be carried out during commissioning and following modifi‐cations, see "Validation", page 26.

• In many cases, depending on the application conditions, the risk assessmentdetermines that regular checks are required, see "Recommendations for regularchecks", page 16.see "Recommendations for regular checks", page 16.

The manufacturer and user must define the type and frequency of the thorough checkson the basis of the application conditions and the risk assessment.

Determination of the thorough checks must be documented in a traceable manner.

4.6.1 Recommendations for regular checks

In many cases, depending on the application conditions, the risk assessment deter‐mines that regular checks are required.

The regular thorough checks serve to investigate the effectiveness of the protectivedevice and discover defects because of modifications or external influences (such asdamage or tampering).

The definition of the necessary intervals and reasons is dependent on vibrations on themachine, among other things, which can be transferred onto the sensors.

Possible regular thorough check intervals or reasons:• When the batch is changed• When the system has been switched off because no object has been detected

(e.g., when the carton magazine is empty)• During repair or maintenance breaks

In many cases, it makes sense to carry out the following checks regularly:• Thorough visual check of the machine and the protective device, page 16• Thorough check of the principal function of the protective device, page 17• Inspection of whether the sensors are still in the correct position• Check of the relevant validation points, see "Validation", page 26• Thorough check of the relevant points on the checklist, see "Checklist for initial

commissioning and commissioning", page 36

If a thorough check discovers a fault, the machine must be shut down immediately. Inthis case, the mounting and electrical installation of application package must bechecked by appropriately qualified safety personnel.

4.6.2 Carrying out thorough checks

Thorough visual check of the machine and the protective device

SICK recommends the following procedure:

b Check whether the machine or the protective device has been modified or manipu‐lated so that the effectiveness of the protective device may be impaired.

b Check the following points in particular.

° Has the machine been retrofitted?

° Have machine parts been removed?

° Have modifications been made to the surroundings of the machine?

° Are there any defective cables or open cable ends?

° Has the protective device been completely or partially dismantled?

° Is the protective device damaged?

° Is the protective device severely contaminated?

° Are the front screens of the sensors contaminated, scratched, or destructed?

° Has the alignment of the sensors been changed?

° Are there any objects (e.g., cables, reflective surfaces) in the detection zone?

4 PROJECT PLANNING


If one of the points applies, the machine must be shut down immediately. In this case,the machine and the protective device must be checked by appropriately qualifiedsafety personnel.

Thorough check of the principal function of the protective device

SICK recommends the following procedure:

b Test the function of the protective device by triggering the protective function andobserving the reaction of the safe outputs using the reaction of the machine, forexample.

° Move an object into the beam of light of the first sensor so that the beam oflight hits the object at a distance of < 30 mm from the sensor (minimumsensing range = 30 ). The OSSD switching outputs of the Flexi Soft safetycontroller must switch to the safe status and stop the dangerous movement.

° Remove the material from the maximum sensing range of the sensor(> 100 mm). The OSSD switching outputs of the Flexi Soft safety controllermust switch to the safe status and stop the dangerous movement.

° Repeat the thorough checks with the second sensor.

If a thorough check discovers a fault, the machine must be shut down immediately. Inthis case, the mounting and electrical installation of application package must bechecked by appropriately qualified safety personnel.

PROJECT PLANNING 4


5 Mounting

5.1 Placing the sensors

Correct distance between the sensors and the material

The sensors must be mounted so that the limits of the detection zone – i.e., the valuesfor the minimum and maximum distance to the object being detected – are compliedwith. The minimum distance is 30 mm; the maximum permissible distance is 100 mm.

Sufficient distance between the light points of the sensors

The sensors must detect the material at two different points. Otherwise, reliable detec‐tion is not possible.

Furthermore, the light points of the two sensors must be far enough from one anotherto eliminate the risk of mutual interference between the sensors.

Positioning the sensors in relation to one another

The sensors should be positioned at a slight angle to the object being detected (seefigure 5). Otherwise, the beam of light could pass through a gap between the objectsand not be reflected inside the detection zone despite material being present. This canlead to an unintended shut-down.

Furthermore, the sensors should be mounted at different heights. The paths of thebeams of the sensors must not run parallel to one another. These measures increaseavailability because this practically eliminates the risk of mutual interference betweenthe sensors.

Figure 5: Sensors aligned at an angle to the material

Interference of the sensors

DANGERThe following types of interference must be ruled out because they could impair thesafety function.• Mirrored, reflective, shiny, or transparent surfaces and holograms are not permit‐

ted in the detection zone.• No light source and no reflective or retroreflective objects may be located in the

extension of the beam path outside of the detection zone (i.e. behind the object tobe detected).

• Direct sunlight or very bright sunlight must be prevented from interrupting thedetection zone of the sensors.

• The sensors must not be illuminated with low-frequency ambient light in the areaaround 100 Hz or with high-frequency ambient light in the kHz range.

5 MOUNTING


5.2 Mounting the sensors

b The sensors are mounted using a suitable mounting bracket, see "Ordering infor‐mation for accessories", page 34.

b Use self-locking nuts.b Do not screw the fixing screws tightly yet because the sensor needs to be real‐

igned after electrical installation, see "Positioning and aligning the sensors",page 22.see "Positioning and aligning the sensors", page 22.

b The maximum permissible tightening torque of the fixing screws is 0.8 Nm.

Power supply and overvoltage protection

The SICK safety controller must be supplied by a SELV/PELV power supply unit.

6 ELECTRICAL INSTALLATION


To protect the sensors effectively against overvoltage on the supply cable, the +24 Voperating voltage for the sensors must be taken from an output of the SICK safety con‐troller rather than directly from a power supply unit (e.g., from output Q1 of an I/O mod‐ule of the SICK safety controller that is permanently set to high).

Prevention of cross-circuits by separate cabling

A cross-circuit between the cables of the sensor to the SICK safety controller may insome circumstances not be detected by the SICK safety controller and must thereforebe prevented by suitable measures when laying or selecting cables.

6.3 Interfaces

Inputs

The input interfaces of the application package are only the power supplies of the FlexiSoft safety controller.

On the SICK safety controller, other interfaces may be used for other functions if theydo not affect the fields of application of the Safeguard Detector application packagethat are described in this document.

Outputs

The output interfaces of the application package are only the safe outputs of the SICKsafety controller that must be configured by the user.

On the SICK safety controller, other interfaces may be used for other functions if theydo not affect the fields of application of the Safeguard Detector application packagethat are described in this document.

ELECTRICAL INSTALLATION 6


7 Configuration

7.1 Safety

DANGERTest the protective device after any changes!The entire protective device must be tested for correct operation after each change ofthe configuration.

7.2 Positioning and aligning the sensors

DANGERThe detection zone of the sensors (30 to 100 mm) cannot be changed. This is why cor‐rect positioning of the sensor is decisive for safe functioning of the Safeguard Detectorapplication package.The application package must switch off the system before the necessary number ofobjects in the infeed for maintaining protection is undercut. Otherwise this would meanthat the user is at risk.

b Apply/switch on power supply (UV = 24 V). The green status LED lights up on thesensor.

b Align the objects how they should be detected in use.b Fill the magazine with objects until intervention is effectively prevented.b Align the sensor at an angle to the front object, see "Positioning the sensors in

relation to one another", page 18.b The red emitted light beam must hit the object within the detection zone (30 to

100 mm). The yellow status LED must light up.b Remove the object so far from the object that the maximum detecting of 100 is

barely exceeded. The yellow Status LED may not light up.b Fix the sensor in the desired position. Observe the maximum permissible tighten‐

ing torque of the fixing screws of 0.8 Nm.b Repeat the procedure for the second scanner.

NOTE

• Ensure that the optical opening (front screen) of the sensor is completely clear.• The sensors are set ex works and ready for operation. No further configuration

adjustments can be made.

At least the following function blocks must be used for the application package logicprogram:

• Frequency monitoring• Tolerant dual-channel evaluation

The two function blocks stated above must be wired exactly as shown in the figure toachieve the defined functionality.

Figure 8: Wiring of the necessary function blocks (example from Flexi Soft Designer 1.7.0)

The release output signal of the tolerant dual-channel evaluation function block can beoptionally used for the following functional expansions:

• External device monitoring• To prevent the machine from starting up unintentionally (reset and restart inter‐

lock)

Configuring the function blocks

DANGERThe parameters stated in this chapter are relevant to safety. The values of these param‐eters must match the values stated here in every application.Exception: parameters that can be changed by the customer or defined depending theapplication specification are identified in the tables.

Configure the frequency monitoring function block for frequency 1 and frequency 2 so thatthey are identical to the following values:

CONFIGURATION 7


Parameter Value

Min. period duration For 2 Hz variant: 340 msFor 10 Hz variant: 70 ms

Max. period duration For 2 Hz variant: 680 msFor 10 Hz variant: 120 ms

Average pulse duration 0 ms (deactivated)

Pulse duration tolerance 0 ms (deactivated)

Frequency x error output 1 All errors

Table 6: Configuration of the frequency monitoring function block

1 This parameter can be changed depending on the application.

Configure the tolerant dual-channel evaluation function block with the following values:

Parameter Value

Input mode Equivalent

Evaluate mode Dual-channel / AND mode

Max. time for AND mode 0 s

Discrepancy time monitoring when switching on Active

Discrepancy time monitoring when switching off Active

Discrepancy time 1 3000 ms

Use input for switch-off delay Not active

Switch-off delay time 0 ms (not active)

Use outputs status input A and status input B 2 Any

Table 7: Configuration of the tolerant dual-channel evaluation function block

1 This parameter can be changed depending on the application. Select as low a discrepancy time as possi‐ble in consideration of availability.

2 This parameter can be changed depending on the application.

Discrepancy time

The discrepancy time parameter in the tolerant dual-channel evaluation function block deter‐mines how long the two inputs may show discrepant values after changing one of thetwo input signals without this being seen as an error. Outputs discrepancy error input Aand discrepancy error input B show which input has not followed in the expected time. Adiscrepancy error (timeout) is reset when the active status has been reached, i.e. a cor‐rect sequence is upheld and the release output therefore becomes High.

The discrepancy time affects the response time of the system and must be consideredwhen designing the entire safety function.

For more information on setting the parameter in the tolerant dual-channel monitoring func‐tion block, see the “Flexi Soft in the Flexi Soft Designer software” operating instruc‐tions.

NOTEThe Evaluate mode parameter of the tolerant dual-channel evaluation function blockmust be configured to Dual-channel / AND mode. The function block then changes to ANDmode when a falling edge occurs at the Actuator released input. In the AND mode, thetolerant dual-channel evaluation function block does not monitor discrepancy time.Otherwise, the function block could detect a discrepancy error when refilling the cartonmagazine, for example, and go into the error state even though the machine hasalready been stopped.

Calculation of the response time of the Safeguard Detector application package

The following formula can be used to calculate the response time of the sub-application(sensor - logic - I/O module output):

Response time of the sensors 2 Hz variant: 500 ms10 Hz variant: 100 ms

+ response time of the Flexi Softsafety controller

For information on calculating the responsetime of the Flexi Soft safety controller, see the“Flexi Soft modular safety controller hardware”operating instructions.

b Only operate the machine when the protective device is functioning properly.

8.1 Validation

The protective device and its application must be thoroughly validated in the followingcases:■ Before commissioning■ After changes to the configuration or the safety function■ After changes to the mounting, the alignment, or the electrical connection■ After exceptional events, such as after manipulation has been detected, after

modification of the machine, or after replacing components

The user is responsible for testing that the Safeguard Detector application package hasbeen mounted and functions correctly on the machine. The following aspects must bechecked and considered during this validation:■ Each of the sensors must be able to request the execution of the safety function

separately.■ The requirements of these operating instructions and the operating instructions of

the individual components have been observed■ Correct selection, combination, arrangement, assembly, and installation of devi‐

ces, including cabling, wiring, and connections■ Detection or effective prevention of cross-circuits between the cables of the sen‐

sors to the SICK safety controller■ Flexi Soft safety controller main module firmware version ≥ V3.00.0■ Suitability of the created logic program■ Suitability of the response time of the Safeguard Detector application package■ Suitability of the discrepancy time in the event of different output signals in the

two sensors■ Prevention of possibilities for manipulation, especially due to changing the posi‐

tion of the sensors or bringing an object into the detection zone of the sensors■ Protection of the Flexi Soft safety controller configuration set by means of a pass‐

word or archiving the validated version, for example■ Compliance with the maximum sensing range if the sensors – no detection if the

hazardous point is not sufficiently covered by a suitable object (e.g., when the car‐ton magazine is empty)

15 Glossary

Response time The protective device’s response time is the maximum timebetween the occurrence of the event leading to the sensor’sresponse and supply of the switch-off signal to the protective devi‐ce’s interface (for example OFF state of the OSSD pair).

OFF state The OFF state is the status of the outputs of the protective device,where the controlled machine is triggered to quit its dangerousstate and the start-up of the machine is prevented (e.g., the volt‐age at the OSSDs is LOW, so that the machine is switched off andremains still).

CCF Common cause failure. Failures of various units due to a singleevent, whereby these failures do not cause each other.

DCavg Average diagnostic coverage (ISO 13849/EN ISO 13849)

Dangerous state A dangerous state is a status of the machine or facility, where peo‐ple may be injured. Protective devices prevent this risk if themachine is operated within its intended use.The figures in this document always show the dangerous state ofthe machine as movement of a machine part. In practice, thereare different dangerous states, such as:

• Machine movements

• Electrical parts

• Visible and invisible beam

• A combination of multiple hazards

MTTFd Mean time to dangerous failure (ISO 13849/EN ISO 13849)

OSSD Output signal switching device: signal output for the protectivedevice, which is used for stopping the dangerous movement.An OSSD is a safety switching output. The functionality of eachOSSD is tested periodically. OSSDs are always connected in pairsand must undergo dual-channel analysis for safety reasons. AnOSSD pair is formed from two OSSDs that are connected and ana‐lyzed together.

PDDB Proximity device with defined behavior under fault conditions: (IEC60947-5-3/EN 60947-5-3)

PFHD Probability of dangerous failure per hour

PL Performance Level (ISO 13849/EN ISO 13849)

Retroreflector A retroreflector is a reflective material that extensively reflects theincoming beam regardless of the alignment of the reflector mainlyin the direction back to the source of the beam (retroflection). Incontrast to this, other bright or reflective materials reflect theincoming light in another direction (incoming angle equals outgo‐ing angle). Examples of retroflectors include rear reflectors onbicycles, high-visibility vests, and the reflective points on guide‐posts.

GLOSSARY 15


Reset When a protective device has sent a stop command, the stoppedstate must be maintained until a reset device is activated and themachine can be restarted in a second step.The reset brings the protective device back to the monitoring stateafter it has sent a stop command. The reset also quits the start-upor restart interlock of a protective device, so that the machine canbe restarted in a second step.The reset must only be possible, when all safety functions and pro‐tective devices are functional.The reset of the protective device must not introduce any move‐ment or dangerous situations itself. The machine is only permittedto start after the reset once a separate start command has beensent.

• Manual resets are performed using a separate, manuallyoperated device, such as a reset pushbutton.

• Automatic resets by the protective device are only permittedin special cases, if one of the following conditions is met:

° It must not be possible for people to be in the hazard‐ous area without triggering the protective device.

° It must be ensured that no people are in the hazardousarea during or after the reset.

Protective field The protective field protects the hazardous area of a machine orvehicle. As soon as the electro-sensitive protective device detectsan object in the protective field, it switches the associated safetyoutputs to the OFF state. This signal can be passed to controllersresulting in the dangerous state coming to an end, e.g. to stop themachine or the vehicle.A horizontal or vertical protective field is required, depending onthe application. The electro-sensitive protective device can there‐fore be mounted in horizontal or vertical alignment, depending onthe requirements.

External device monitoring The external device monitoring (EDM) monitors the status of down‐stream contactors.In order to use the external device monitoring, positively guidedcontactors must be used to switch off the machine. If the auxiliarycontacts of the positively guided contactors are connected to theexternal device monitoring, the external device monitoring checkswhether the contactors drop off when the OSSDs are switched off.

SIL Safety integrity level

SILCL SIL claim limit: (IEC 62061/EN 62061)

Restart interlock The restart interlock prevents the machine from automaticallystarting up, for example after a protective device has respondedwhile the machine is operating or after changing the machine’soperating mode.The restart interlock can be implemented in the protective deviceor in the safety controller.A command to reset the protective device must be given, for exam‐ple using a reset pushbutton, before the machine can berestarted.
