3.2 Principle of operation
VEGAMET 391 mit SIL-Qualikation is a universal signal conditioning
instrument for a variety of applications such as level, gauge and pro-
cess pressure measurement. At the same time, it can serve as power
supply unit for connected sensors. VEGAMET 391 mit SIL-Qualika-
tion is designed for connection of any 4 … 20 mA sensor.
Due to the SIL qualication, the instrument can be used in a safety-
relevant protective function. With single channel architectur, SIL2 is
reached, with multiple channel, diversitary architecture, SIL3. Take
note of the specications and requirements of the "Safety Manual".
The VEGAMET 391 mit SIL-Qualikation signal conditioning instru-
ment can power the connected sensor and process its measurement
signals.The requested parameter is shown on the display and also
outputted to the integrated current output for further processing. The
measurement signal can thus be transferred to a remote display or a
superordinate control system. Operating relays for control of pumps or
other devices are also integrated.
Wide range power supply unit with 20 … 253 V AC/DC for worldwide
use.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3 Adjustment
The instrument can be adjusted with the following adjustment media:
• With integrated display and adjustment unit
• an adjustment software according to FDT/DTM standard, e.g.
PACTware and a Windows PC
The entered parameters are generally saved in VEGAMET 391 mit
SIL-Qualikation, when used with PACTware and PC also optionally
in the PC.
Information:
When using PACTware and the respective VEGA DTM, additional set-
tings can be carried out which are not possible or only partly possible
