Usable lifetime: According to IEC 61508-2 §7.4.7.4 values of up to 10 years can be as-
sumed. Different values can be used based on the experience of the user. In principle,
critical applications and cases of operation (e. g. highly permeable or solid loaded media)
can reduce the usable lifetime. For safe and reliable operation please follow the relevant
instructions documented in the manual.
The evidence is based on proven in use combined with a FMEDA.
