VEGASON 66
l
PC with PACTware™ and suitable VEGA DTM
l
VEGACONNECT 3 with HART adapter cable

4 … 20 mA processing
Note:
For processings with integrated HART resistance (inner
resistance approx. 250 Ohm), there is no additional, external
resistance necessary. In such cases, VEGACONNECT 3 can
be connected in parallel to the 4 … 20 mA cable.
7.2 Parameter adjustment with PACTware™
Further setup steps are described in the operating instructions
manual "DTM Collection/PACTware™" attached to each CD
and which can also be downloaded from our homepage. A
detailed description is available in the online help of
PACTware™ and the VEGA DTMs.
