8.1

Connect the PC

Fig. 31: Connection of the PC directly to the sensor via the interface adapter
1 USB cable to the PC
2 Interface adapter VEGACONNECT
3 Sensor

Fig. 32: Connecting the PC via HART to the signal cable
1 Sensor
2 HART resistance 250 Ω (optional depending on evaluation)
3 Connection cable with 2 mm pins and terminals
4 Processing system/PLC/Voltage supply
5 Interface adapter, for example VEGACONNECT 4
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 VEGAMET
381, VEGAMET 391. Common Ex separators are also usually
equipped with a sufficient current limiting resistance. In such cases,
the interface adapter can be connected parallel to the 4 ... 20 mA
cable (dashed line in the previous illustration).

Parameter adjustment with PACTware

For parameter adjustment of the sensor via a Windows PC, the con-
figuration software PACTware and a suitable instrument driver (DTM)
