Safety switch PSEN cs4.1
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 modifications are carried out.
}Do not remove the protective cap until you are just about to connect the unit.
Unit features
}Transponder technology
}Coding: fully coded
}Dual-channel operation
}2 safety inputs for series connection of multiple safety switches

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 actuator.

The outputs cannot be switched back on until there is a low signal at both inputs simultaneously.
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).

Wiring
Please note:
}Information given in the "Technical details" must be followed.
}Calculation of the max. cable length lmax in the input circuit:
Imax = Rlmax
Rl / km
Rlmax = Max. overall cable resistance (see Technical details [
20]
Rl / km = cable resistance/km

Connection to evaluation devices
Please note:
}The power supply must meet the regulations for extra low voltages with safe separation (SELV, PELV).
}The inputs and outputs of the safety switch must have a safe separation to voltages over 60 V AC.
CAUTION!
The safety outputs must use 2-channel processing.
