6.4 Proof test (WHG, SIL)
The implementation of the proof test according to WHG is stipulated
in the general type approval, item 8.
Take note of these higher-ranking approvals if VEGASWING 63 Ex is
used as part of an overfill protection system according to WHG.
The following instrument combinations meet the requirements ac-
cording to WHG:
VEGASWING 63 Ex with
•
Oscillator SWE60Z EX
•
Signal conditioning instrument VEGATOR 121, 122, 636 Ex,
VEGALOG or SPLC (safety-oriented PLC)
The VEGASWING 63 is qualified for use in measuring chains of level
SIL2 according to IEC 61508 (redundant, level SIL3) and is approved
according to WHG.
The measuring system can be used for level detection of liquids and
meets the special requirements of safety technology.
This is possible up to SIL2 in a single channel architecture (1oo1D),
and up to SIL3 in a multiple channel, redundant architecture.
The following instrument combinations meet the requirements ac-
cording to SIL:
VEGASWING 63 Ex with
•
Oscillator SWE60Z EX
•
Signal conditioning instrument VEGATOR 636 Ex or SPLC (safety-
oriented PLC)
•
Oscillator SWE60Z EX
•
VEGATOR 121, 122 signal conditioning instrument
