4.2 Adjustment with PC
When using a sensor in conjunction with a
VEGA signal conditioning instrument, use a
communication resistor according to the
following schedule:
4 Set-up
4.1 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 VVO (VEGA
Visual Operating System) in version
≥ 2.70
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 41 radar sensors, like other
HART
® protocol compatible instruments, can
be adjusted with the HART ® handheld. A
manufacturer-specific DDD (Data-Device-
Description) is not required. The radar sen-
sors are adjusted with the HART
® standard
menus. All main functions are therefore ac-
cessible.
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.
