Siemens SINUMERIK HT 10 User Manual

Category 3
Performance Level PL d
Note
The quantitative assessment of the emergency stop safety function must be based on the B
10d
value corresponding to the used standards (e.g. ISO 13849-1) under consideration of the
respective application (frequency of the actuation, service life, diagnostics by the evaluation
unit, etc.). The B
10d
value only applies when the technical properties of the emergency stop
button are taken into account.
When using the connection box advanced, the speci󹪝ed failure probability (PFH
d
) must be taken
into account. This value only applies if the technical properties of the connection box advanced
and the quantitative conditions speci󹪝ed here (e.g. service life) are observed.
