Safety
Intended use
Safety function of safety switch:
The safety functions of the safety switch are:
}Safe shutdown of safety outputs when the actuator is removed beyond the assured re-
lease distance sar or when the actuator is not detected
}Remain shut down safely after the actuator has been removed
The safety switch meets the requirements in accordance with:
}EN 60947-5-3: PDDB with one of the approved actuators
}EN 62061: SIL CL 3
}EN ISO 13849-1: PL e (Cat. 4)
}ENISO14119: Coding level High, type 4
The safety switch may only be used with one of the approved actuators.
The following combinations from safety switch and actuator is permitted:
Safety switch Approved actuators
PSEN cs4.1n PSEN cs4.1
PSEN cs2.1
The safety level PL e (Cat. 4)/SIL CL 3 is only achieved if
}the safety outputs use 2-channel processing.
The following is deemed improper use in particular
}Any component, technical or electrical modification to the product,
}Use of the product outside the areas described in this manual,
}Use of the product outside the technical details (see Technical details [ 22]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product

Safety regulations
Safety assessment
Before using a device it is necessary to perform a safety assessment in accordance with
the Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion,
}Have read and understood the information provided in the section entitled Safety
}Have a good knowledge of the generic and specialist standards applicable to the spe-
cific application.
Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}Damage can be attributed to not having followed the guidelines in the manual,
}Operating personnel are not suitably qualified,
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
Disposal
}In safety-related applications, please comply with the mission time TM in the safety-re-
lated characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

For your safety
WARNING!
Loss of safety function due to manipulation of the interlocking device
Manipulation of the interlocking device may lead to serious injury and death.
– You should prevent any possibility of the interlocking device being
manipulated through the use of a spare actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If spare actuators are used, these must be installed as described in
Installation [ 14].
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}Do not remove the connector's protective cap until you are just about to connect the
unit. This will prevent potential contamination.
Unit features
}Transponder technology for presence detection
}Pilz coding type: fully coded
}Dual-channel operation
}2 safety outputs
}LED display for:
– State of the actuator
– Supply voltage/fault
}1 direction of actuation
}5-pin M12 male connector
Function description
The safety outputs may have a high or low signal, depending on the position of the actu-
ator.
In a safe condition there is a low signal at the safety outputs.
