l PC with PACTware and suitable VEGA DTM
l VEGACONNECT
l HART resistor approx. 250 Ω
l P ower supply unit or processing system
Note:
W
ith power supply units with integrated HART resistance (internal
resistance approx. 250 Ω), an additional external resistance is not
necessary. This applies, e. g. to the VEGA instruments VEGATRENN
149A, VEGADIS 371, VEGAMET 381). C
ommon Ex separators are
also usually equipped with a sufficient current limitation resistance. In
such cases, VEGACONNECT 4 can be connected parallel to the
4 … 20
mA cable.
7.2 Parameter adjustment with PACTware
F urther 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.
Note:
K
eep in mind that for setup of VEGABAR 52, DTM-Collection in the
actual version must be used.
