4 Setup
4.1 Adjustment media
Series 50 sensors can be adjusted with the
- PC (adjustment program VVO)
- detachable adjustment module MINICOM
- HART
® handheld.
It is only possible to use one adjustment
device at a time.
Adjustment module MINICOM
With the adjustment module MINICOM, you
can adjust directly in the sensor or in the
external indicating instrument VEGADIS 50.
With a dialogue text display and 6 keys, the
module offers the same adjustment function-
ality as the adjustment software VVO.
Adjustment program VVO
With the adjustment program VVO
(VEGA
Visual Operating System) on the PC, the
sensors can be adjusted in a very conven-
ient, user-friendly manner. The PC communi-
cates with the sensor via the interface
converter VEGACONNECT 2 or 3. A digital
adjustment signal is superimposed on the
signal and supply cables. The PC can be
connected at any location along the cable or
directly to the sensor.
HART ® handheld
VEGAFLEX 50 K sensors, like other HART ®
protocol-compatible instruments, can be
adjusted with the HART
® handheld. A manu-
facturer-specific DDD (Data Device Descrip-
tion) is not required. The sensors
communicate with the HART
® standard
menus, through which all sensor functions
are accessible. Functions that are rarely
used, such as, for example, the scaling of the
A/D converter for the signal output or the
adjustment with medium, are not possible or
are blocked with the HART
® handheld. These
functions must be carried out with the PC or
the adjustment module MINICOM.
4.2 Adjustment with the adjustment
module MINICOM
Just as with the PC, you can adjust the sen-
sor with the small, detachable adjustment
module MINICOM. The adjustment module is
plugged into the sensor or into the external
indicating instrument (optional).
All the adjustment options provided by a PC
with the adjustment program VVO are also
available with the adjustment module
MINICOM. You can carry out all adjustment
steps with the 6 keys of the adjustment mod-
ule. A small display shows you, apart from
the measured value, a short message on the
menu item or an entered numerical value.
