3 Product description3.1 Setup and functionThe safety switch consists of two components:•SensorThe sensor is mounted on the fixed part of the protective device.•Actuator (transponder)The actuator is mounted on the moving part of the protective device.When the protective device is closed, the actuator is guided to the sensor. When theswitch on distance is reached, the sensor detects the actuator code. If the sensordetects a taught-in code (valid actuator), it sets safety outputs OSSD 1 and OSSD 2(semiconductor outputs) to High and application diagnostic output Aux to Low.When the protective device is opened, the actuator is removed from the response rangeof the sensor. The sensor sets safety outputs OSSD 1 and OSSD 2 to Low and applica‐tion diagnostic output Aux to High.3.2 Product characteristics3.2.1 Product variantsThe safety switch is delivered in different variants. You will find an overview of impor‐tant distinguishing features of the variants in the following.•Universally coded, unique coded, and permanently coded safety switches•Actuator design: “Standard”, “Flat”, or “Mini”•Cable with M12 plug connector (5-pin or 8-pin) or flying leads (3 m or 10 m)Complete overview of all variants: see "STR1 ordering information", page 40.Coding•Universally codedAll actuators are accepted. No teach-in is required.•Unique codedAn actuator must be taught in during commissioning. Up to 8 actuators may betaught in one after the other. Only the most recently taught-in actuator is valid.Previously taught-in actuators can no longer be used.•Permanently codedAn actuator must be taught in during commissioning. Teach-in only needs to beperformed once. It is not possible to teach in any further actuators.3.2.2 Active sensor surfacesThe sensor has 3 active sensor surfaces:•Front: black surface•2 x sides: yellow surface with long black edge3.2.3 Fault detectionFaults that arise, including internal device faults, are detected no later than the nextrequirement to close the safety contacts (e.g., when the machine starts). The safetyswitch then switches to the safe state. If a fault is detected, the safety circuit isswitched off and the DIAG and STATE light emitting diodes display the fault (seetable 10).3 PRODUCT DESCRIPTION10 O P E R A T I N G I N S T R U C T I O N S | STR1 8018754/2016-xx-xx | SICKSubject to change without noticeDraft 2016-10-19
3.2.4 CascadingIn the case of cascading, up to 30 safety switches are connected in series.For more information, see "Cascading", page 16 and see "Connecting a cascade",page 253.2.5 State indicatorsThe STATE light emitting diode (red/green) and the DIAG light emitting diode (yellow)signal the operational state of the safety switch.Complete overview of the light emitting diode states and their meanings: see "Diagnos‐tic LEDs", page 30.3.2.6 Protective functionsThe safety switch has the following internal protective functions:•Short-circuit protection at all outputs•Cross-circuit monitoring at OSSDs•Overload protection at OSSDs•Reverse polarity protection for the supply voltagePRODUCT DESCRIPTION 38018754/2016-xx-xx | SICK O P E R A T I N G I N S T R U C T I O N S | STR1 11Subject to change without noticeDraft 2016-10-19
4 Project planning4.1 Manufacturer of the machineDANGERFailure to comply with manufacturer’s obligationsHazard due to lack of effectiveness of the protective devicebPerform a risk assessment before using the safety switch.bDo not manipulate, open, or modify components of the safety switch.bDo not repair defective devices; replace them instead.bMake sure the switch-on commands that cause the machine to enter a dangerousstate only take effect when the protective device is closed.bMake sure a stop command is triggered when the protective device is opened in ahazardous machine state.bSafety switches must not be bypassed (i.e., the contacts jumpered), swiveled outof the way, removed, or rendered ineffective in any other way. If necessary, takemeasures to reduce the possibility of bypassing.If multiple devices are connected in series (cascaded) and the simplified procedureaccording to ISO 13849 is used to determine the performance level (PL), the PL maydrop.As the number of safety switches in a cascade increases, so too does the responsetime.4.2 Operating entity of the machineDANGERFailure to comply with operating entity’s obligationsHazard due to lack of effectiveness of the protective devicebModifications to the machine and modifications to the mechanical mounting ofthe safety switch necessitate a new risk assessment. The results of this riskassessment may require the operating entity of the machine to fulfill the manufac‐turer’s obligations.bApart from during the procedures described in this document, the components ofthe safety switch must not be opened or modified.bDo not perform repair work on the components. Improper repair of the safetyswitch can lead to a loss of the protective function.bMake sure that bypassing is not carried out by substitute actuators.

4.3 DesignDANGERBypassing the protective deviceHazard due to lack of effectiveness of the protective devicebPrevent incentives to manipulate the safety switch by taking at least one of the fol‐lowing measures:Universally coded variant only:°Cover the sensor and the actuator with additional equipment or protect themagainst access.°If possible, use non-detachable mounting methods for actuators (such aswelding, gluing, safety screws, or rivets).Mounting locationbWhen the protective device is closed, the sensor and actuator must face eachother at the safe switch on distance of Sao or closer (see table 3).bSelect a mounting location that allows the sensor and actuator to be accessed formaintenance work and protects them against damage.bIf possible, mount the sensor and actuator on non-ferrous subsurfaces and at adistance from metallic parts in order to avoid affecting the sensing range. If this isnot possible, the effect on the safe switch on distance Sao and the safe switch offdistance Sar must be checked.bMake sure that there is no possibility of hazards arising when the protective deviceis opened, even if the actuator has not yet reached the safe switch off distanceSar.bIf the actuator is approaching the sensor in a parallel position, observe the mini‐mum distances (see table 3).bIf necessary, attach an additional stop for the moving protective device.DistanceIf multiple safety switches are mounted on the machine, they must be mounted with aminimum distance in relation to one another; see "Mounting", page 20.AlignmentThe sensor can be mounted in any alignment see "Mounting", page 20, see "Possiblemounting types", page 18.Actuating directionThe actuator may approach the front or the long side of the sensor.NOTEIf the actuator does not move directly onto the sensor when the protective device isclosed, but instead approaches it in a parallel position, the specified minimum distancemust be adhered to. This prevents the sensor from enabling the safety outputs despitethe protective device not being fully closed.4.4 Integration into the electrical controlSwitch-on commands that cause the machine to enter a dangerous state may only takeeffect when the protective device is closed. In cases where the machine is in a danger‐ous state, a stop command must be triggered if the protective device opens. Dependingon the safety concept, the signal is analyzed by, e.g., safety relays or a safety controller.PROJECT PLANNING 48018754/2016-xx-xx | SICK O P E R A T I N G I N S T R U C T I O N S | STR1 13Subject to change without noticeDraft 2016-10-19
4.4.1 OSSDsSafety switches with local inputs and outputs can be directly integrated into themachine controller.DANGERHazard due to lack of effectiveness of the protective deviceIn the case of non-compliance, it is possible that the dangerous state of the machinemay not be stopped or not stopped in a timely manner.bMake sure that the following control and electrical requirements are met so theprotective function can be fulfilled.•The output signals from an OSSD pair must not be connected to each other.•In the machine controller, both signals from an OSSD pair must be processed sep‐arately.Figure 1: Dual-channel and isolated connection of OSSD 1 and OSSD 2•The machine must switch to the safe state at any time if at least one OSSD in anOSSD pair switches to the OFF state.•Prevent the formation of a potential difference between the load and the protec‐tive device. If you connect loads to the OSSDs (safety outputs) that then alsoswitch if controlled with negative voltage (e.g., electro-mechanical contactor with‐out reverse polarity protection diode), you must connect the 0 V connections ofthese loads and those of the corresponding protective device individually anddirectly to the same 0 V terminal strip. In the event of a fault, this is the only way toensure that there can be no potential difference between the 0 V connections ofthe loads and those of the corresponding protective device.Figure 2: No potential difference between load and protective device4 PROJECT PLANNING14 O P E R A T I N G I N S T R U C T I O N S | STR1 8018754/2016-xx-xx | SICKSubject to change without noticeDraft 2016-10-19
DANGERHazard due to lack of effectiveness of the protective deviceIn the case of non-compliance, it is possible that the dangerous state of the machinemay not be stopped or not stopped in a timely manner.Downstream contactors must be positively guided and monitored depending on appli‐cable national regulations or required reliability of the safety function.bMake sure that downstream contactors are monitored (external device monitoring,EDM).Requirements for the electrical control of the machine•Use the control without test pulses. The safety switch is self-testing.•The safety switch tests the OSSDs at regular intervals. To do this, it switches eachOSSD briefly (for max. 1 ms) to the OFF state and checks whether this channel isvoltage-free during this time.Make sure that the machine’s control does not react to these test pulses and themachine does not switch off.•The inputs of a connected evaluation unit must be positive-switching (PNP), as thetwo outputs of the safety switch send a level of the supply voltage in the switched-on state.The OSSDs are short-circuit protected to 24 V DC and 0 V. When the actuator is in thesensor’s response range, the OSSDs signal the ON state with the HIGH signal level(non-isolated). If the actuator is removed from the sensor’s response range or there is adevice fault, the OSSDs signal the OFF state with the LOW signal level.The safety switch complies with the regulations for electromagnetic compatibility (EMC)for the industrial sector (Radio Safety Class A). Radio interference cannot be ruled outwhen used in residential areas.DANGERHazard due to lack of effectiveness of the protective deviceIn the case of non-compliance, it is possible that the dangerous state of the machinemay not be stopped or not stopped in a timely manner.bMake sure that the following control and electrical requirements are met so thesafety switch can fulfill its protective function.•The external voltage supply of the safety switch must be capable of buffering briefpower failures of 20 ms as specified in IEC 60204-1.•The power supply unit must provide safe isolation according to IEC 61140 (SELV/PELV). Suitable power supply units are available as accessories from SICK.4.4.2 Application diagnostic outputThe application diagnostic output signal changes as soon as the actuator is moved intoor leaves the response range of the safety switch. In other words, it does so when themoving protective device is opened and closed. This is not a safety output.Actuator Application diagnostic outputActuator not in response range.

4.5 Thorough check conceptThorough checks must be performed on the safety switch by appropriately qualifiedsafety personnel during commissioning, after modifications, and at regular intervals.see "Thorough check", page 29Regular thorough checks serve to investigate the effectiveness of the safety switch anddiscover defects resulting from modifications or external influences (such as damage ormanipulation).The manufacturer and operating entity must define the type and frequency of the thor‐ough checks on the machine on the basis of the application conditions and the riskassessment. The process of defining the thorough checks must be documented in atraceable manner.4.5.1 Minimum requirements for regular thorough checksThe following thorough checks must be carried out at least once a year:•Thorough check of the principal protective function of the safety switch•Thorough check of the safe sensing range Sar•Thorough check for damage on the switch housing•Thorough check for damage on the switch cables•Thorough check for signs of misuse or manipulation on the safety switchPROJECT PLANNING 48018754/2016-xx-xx | SICK O P E R A T I N G I N S T R U C T I O N S | STR1 17Subject to change without noticeDraft 2016-10-19

7 Commissioning7.1 SafetyDANGERHazard due to lack of effectiveness of the protective deviceIn the case of non-compliance, it is possible that the dangerous state of the machinemay not be stopped or not stopped in a timely manner.1. Have qualified safety personnel perform a thorough check on the machine andapprove it before commissioning.2. Make sure that the time for the safety requirement (closing the protective deviceagain) is longer than the risk time.7.2 Switching onThe device initializes after switching on. During this process, the OSSDs are switchedoff and the light emitting diodes light up alternately in the color sequence green, red,and yellow. For unique coded and permanently coded safety switches only: If any actua‐tors have already been taught in, the STATE light emitting diode will flash once after ini‐tialization for each taught-in actuator.7.3 Teach-inDANGERBypassing the protective deviceThe dangerous state may not be stopped in the event of non-compliance.bIf an actuator is taught in, document thisbDuring regular thorough checks, make sure that the taught-in actuator is still beingused.Variant for universally coded actuatorsNo teach-in is required.Variant for unique coded actuatorsAn actuator must be taught in during commissioning. Up to 8 actuators may be taughtin one after the other. Only the most recently taught-in actuator is valid.
