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.
