search".
3.2 Principle of operation
VEGASCAN 693 is a universal signal conditioning instrument for a
number of applications such as level, gauge and process pressure
measurement. At the same time, it can serve as power supply unit for
connected sensors. VEGASCAN 693 is designed for connection of 15
independent VEGA HART sensors (5 with Ex applications). Hence 15
(5 with Ex) independent measurements can be carried out.
On instruments with one of the optional interfaces (RS232/Ethernet),
the measured values can be retrieved via modem or network and
displayed by means of a web browser, Visual VEGA or WEB-VV. It is
also possible to send measured values and messages via e-mail. The
use of VEGASCAN 693 is particularly suitable for stocktaking, VMI
(Vendor Managed Inventory) and remote enquiry.
VEGASCAN 693 signal conditioning instrument can power up to
15 HART sensors and also evaluates their measuring signal via the
same cable. The measured value transmission is carried out via a
digital bus system (HART multidrop). The requested parameter is
shown in the display and, in addition, outputted to the integrated
interface and the web server for further processing. On request, the
measured values can be sent event or time-controlled via e-mail to
different addressees.
Wide-range power supply unit with 20 … 253 V AC/DC for world-wide
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 VEGASCAN 693,
when used with PACTware and PC also optionally in the PC.
Information:
When using PACTware and the corresponding VEGA DTM, additional
settings can be carried out which are not possible or only partly pos-
sible with the integrated display and adjustment unit. When using an
adjustment software, you either need one of the integrated interfaces
(RS232/Ethernet) or the interface converter VEGACONNECT.
Further instructions for setting up the web server and e-mail functions
can be found in the online help of PACTware or the VEGASCAN 693
