5.2 Adjustment with PC
When using a sensor in conjunction with a
VEGA signal conditioning instrument, use a
communication resistor according to the
following schedule:
5 Set-up
5.1 Adjustment media
Radar sensors can be adjusted with the
- PC (adjustment software PACT
ware TM )
- detachable adjustment module
MINICOM
- HART ® handheld.
The adjustment must be carried out with only
one adjustment device. If, for example, you
attempt to adjust the parameters with the
MINICOM and the HART
® handheld at the
same time, the adjustment will not work.
PC
With the adjustment program PACT ware TM on
the PC, you can adjust the radar sensors
quickly and conveniently. The PC communi-
cates via the interface adapter
VEGACONNECT 3 with the sensor. During
the process, a digital adjustment signal is
superimposed on the signal and supply
cable. The adjustment can be carried out
directly on the sensor or at any desired loca-
tion along the signal cable.
Adjustment module MINICOM
With the adjustment module MINICOM, you
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 functionality as
the adjustment software VVO.
HART ® handheld
VEGAPULS radar 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 radar sensors are
adjusted with the HART
® standard menus. All
main functions are therefore accessible.
Functions that are rarely used, such as, for
example, scaling of the A/D converter for
signal output or adjustment with medium, are
not possible or are blocked with the HART
®
handheld. These functions must be carried
out with the PC or the MINICOM.
