4.3.3.3 Connection example
Connection example 4- ][Funktion_STO_Beispiel_einkanalig_1
The following circuit example illustrates single-channel activation of the
safety function STO.
 The drives are switched via a safety gate.
 Safety gates S1/S2 are monitored by a safety relay PNOZ s3.
 Shorts across contacts are detected.
 The safety relay is wired for an automatic reset.
 The safety function STO complies with PL d (Cat. 2) of EN ISO 13849-
1 and SIL CL 2 of EN/IEC 62061.
The relays' wiring must comply with the category or performance level
required for the application. Further information on the safety relays is
available from Pilz.
