Festo — CMMT-AS-...-S1 — 2021-04d
Technical data
–
Depending on the desired safety classification, evaluation of the SBA diagnostic output by the
safety relay unit is either mandatory or optional.
–
To achieve the safety classification Cat. 3, PL d, SIL 2 (or also Cat. 2, PL c/d) in conjunction with 2
brakes, evaluation of the SBA diagnostic output is mandatory.
–
If you require an SBC function with a classification higher than Cat. 1, PL c, the diagnostic outputs
must be checked regularly – at least 1 x once every 24 h – by having them tested automatically by
the safety relay unit (
è
EN ISO 13849-1, Annex G.2).
–
The safety relay unit must request the safety sub-function at least once within 24 h and thereby
monitor the SBA diagnostic output to achieve a diagnostic coverage of at least 60 %. If the signal
behaviour does not correspond to expectations, the system must be put into a safe condition within
the reaction time. It is essential that time monitoring be provided in the safety controller.
The technical data for the safety sub-function SS1 must be calculated individually according to the
application. Use the specified safety reference data for STO and SBC for the calculation.
