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
