Attainable safety level

The CMMO-ST with STO function fulfils the requirements of the test basis for
– Category 3 / PL e per EN ISO 13849-1,

and can be used in applications up to Cat. 3 / PL e per EN ISO 13849-1 and SIL 3 according
EN 62061 / IEC 61508. The attainable safety level also depends on the other components used to real-
ise the safety function.
• For emergency stop applications, protection against automatic restart corresponding to the re-
quired safety category must be furnished. Among other means, this can take place through an ex-
ternal safety switching device.
