1 VEGABAR 66
2 HART resistance 250 Ω (optional depending on processing)
3 Connection cable with 2 mm pins and terminals
4 Processing system/PLC/Voltage supply
Necessary components:
•
VEGABAR 66
•
PC with PACTware and suitable VEGA DTM
•
VEGACONNECT
•
HART resistance approx. 250 Ω
•
Power supply unit or processing system
Note:
With 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. Common 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.

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.
Note:
Keep in mind that for setup of VEGABAR 66, DTM-Collection in the
actual version must be used.
All currently available VEGA DTMs are included as a DTM Collection
on a CD. They can be purchased for a token fee from the responsible
VEGA agency. In addition, the actual PACTware version is also avail-
able on this CD.
In addition, this DTM Collection incl. the basic version of PACTware
can be downloaded free of charge from the Internet. Move via www.
vega.com and "Downloads" to "Software".
