(Safety-Related Control Function)
The
manufacturer
of
the machine and/or final apparatus must perform, maintain and make available a
Risk Assessment (risk analysis) of the machine in accordance with the ISO12100 and ISO14121
standards, and implement all necessary measures to avoid unforeseen movements that can cause
damage to persons or objects. In particular, the manufacturer of the machine and/or final apparatus
has to comply with the relevant product standards. Where it has been chosen to perform safety
functions by means of electrical/electronic devices (SCRF), the safety integrity levels (SIL) and the
functional requirements of each device must be specified clearly. According to TECHNICAL STANDARD
IEC EN CEI EN 62061: 2005 +A1:2013 +A2:2015, this specification must include all information likely
to influence the design of the electrical/electronic device, including, where applicable:
l
The machine operating conditions
l
Prioritization of functions that can be active simultaneously and cause conflicting actions
