4.1 Adjustment methods
Series 50 sensors can be adjusted with
- PC (adjustment program VVO)
- with detachable adjustment module
MINICOM
- with HART ® handheld.
It is only possible to use one adjustment
device at a time.
Adjustment module MINICOM
With the adjustment module MINICOM you
adjust in the sensor or in the external indicat-
ing instrument VEGADIS 50. With a dialogue
text display and 6 keys, the module offers
the same adjustment functionality 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 user-
friendly way. The PC communicates via the
interface converter VEGACONNECT 2 with
the sensor. 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 adjustment
module MINICOM
As with the PC, you can also 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).
For the adjustment with adjustment module,
all adjustment options as with the PC and the
adjustment program VVO are available. You
carry out all adjustment steps with the 6 keys
of the adjustment module. A small display
shows you, apart from the measured value, a
short message on the menu item or an en-
tered numerical value.
