Functional safety (SIL)
The instrument can be used in safety-instrumented systems according to IEC 61508/IEC 61511-1
(service proven).
If the instrument is already ordered with SIL qualification Ex factory, then the corresponding Safety
Manual with information on the topic "Functional safety (SIL)" is part of the shipment.
If the instrument is ordered Ex factory without SIL qualification, then the corresponding Safety
Manual is available under "www.vega.com", "Downloads", "Approvals".
Approvals
Instruments with approvals can have different technical data depending on the version.
For that reason the associated approval documents of these instruments have to be carefully
noted. They are part of the delivery or can be downloaded under www.vega.com via "VEGA Tools"
and "serial number search" as well as via "Downloads" and "Approvals".
