up to:
– Performance Level e, Cat. 4 in accordance with
EN ISO 13849-1
– Safety integrity level SIL 3 in accordance with EN 61508

used to implement the safety function.
Make sure that the overall safety function of the system is
•
analysed and validated.
It is the responsibility of the operator to determine and
verify the required safety rating (safety integrity level,
performance level and category) of the system.
Note the residual risks in your system that remain despite
•
measures taken to integrate safety during design and
building, despite safety precautions and despite supple­
mentary protective measures.
These residual risks are also influenced by your safety
specifications and the safety characteristics of your
system.
