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
– PSEN cs4.2 M12/8-0.15m: Connector 8 pin M12

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.
State of the inputs and outputs:

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).

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.

When several units are connected in series, the delay-on de-energisation
time increases in direct proportion to the number of interconnected safety
switches.
