Safety switch PSEN cs4.2

The safety switch meets the requirements in accordance with:

}EN 60204-1 and IEC 60204-1

}EN 60947-5-3 with the actuator PSEN cs4.1

}EN 62061: SIL CL 3

}EN ISO 13849-1: PL e and Cat. 4

The safety switch may only be used with the corresponding actuator PSEN cs4.1.

The safety outputs must use 2-channel processing.

For your safety

}Only install and commission the unit if you have read and understood these operating

instructions and are familiar with the applicable regulations for health and safety at work

and accident prevention.

Ensure VDE and local regulations are met, especially those relating to safety.

}Any guarantee is rendered invalid if the housing is opened or unauthorised modifica-

tions are carried out.

}Do not remove the protective cap until you are just about to connect the unit.

Unit features

}Transponder technology

}Coding: uniquely coded

}Dual-channel operation

}2 safety inputs for series connection of multiple safety switches

}2 safety outputs

}1 signal output

}LED for:

– State of the actuator

– State of the inputs

– Supply voltage/fault

}1 direction of actuation

}Connection types:

– PSEN cs4.2a: Cable, 5 m

– PSEN cs4.2b: Cable, 10 m

– PSEN cs4.2p: 8 pin M8 connector

Function description

There is a high signal or a low signal at the safety outputs, depending on the position of the

actuator and the state of the inputs. The signal output Y32 signals the position of the actua-

tor.

The outputs cannot be switched back on until there is a low signal at both inputs simultane-

ously.

Safety inputs S11 and S21 are monitored for feasibility. A high signal can be present at the

inputs at offset times; the low signal must be present at both inputs simultaneously (partial

operation lock).
