Set-up
Connection
In chapter "2.2 Configuration of measuring
systems“ the connection of the PC is shown in
the various coordinations. The PC with the
adjustment program VVO (VEGA Visual Oper-
ating) can be connected to the
- sensor or
- signal line.
PC on the sensor
For connection of the PC to the sensor you
require the interface converter
VEGACONNECT 2. Insert VEGACONNECT 2
into the provided CONNECT-socket in the
sensor.
PC on the signal line
Connect the two-wire line of VEGACONNECT 2
to the signal or supply line (two-wire sensor) of
the sensor. When the resistors of the systems
(DCS, current source etc.) connected to the
signal/supply line are less than 250
Ω,
a resis-
tor of 250␣ …␣ 350␣
Ω
must be connected to the
signal/supply line during adjustment. The
digital signals modulated to the signal line
would be damped extremely or "short-
circuited“ by too small system resistors so that
the communication with the PC will be inter-
fered.
The individual adjustment steps are marked in
the following with a dot.
Example:
• Choose …
• Start …
When you have connected the PC with the
adjustment software VVO to your measuring
system
• first switch on the power supply of the con-
nected sensor.
The sensor needs in the first 10 … 15 seconds a

6.1 Adjustment structure
VEGAPULS 56 radar sensors can be adjusted
with
- PC (adjustment program VVO),
- detachable adjustment module MINICOM or
- HART
®
-handheld.
The adjustment must only be carried out with
one adjustment medium at the same time.
Adjustment program VVO
With the adjustment program VVO (VEGA
Visual Operating) on the PC you can adjust the
radar sensors very comfortably. The PC com-
municates via the interface converter
VEGACONNECT␣ 2 with the sensor. A digital
adjustment signal is superimposed to the
signal and supply line. The adjustment can be
carried out in any individual position of the
signal line or directly on the sensor.
Adjustment module MINICOM
With the adjustment module MINICOM you can
adjust in the sensor or in the external indicat-
ing instrument VEGADIS 50. The adjustment
module enables via text display with 6-key
field the adjustment with the same function
volume than with the adjustment program
VVO.
HART ® -handheld
VEGAPULS 56K radar sensors can be ad-
justed beside the PC and the adjustment
module MINICOM also with the HART
®
-
handheld. A manufacturer specific DDD (Data-
Device-Description) is not necessary. The
radar sensors communicate with the HART
®
-
standard menus. All sensor functions will be
accessible. Some very rarely used functions
such as e.g. the scaling of the di-gital, ana-
logue converter for the signal output or the
adjustment with medium are not possible with
the HART
® -handheld or are blocked. These
functions can be carried out with the PC or the
MINICOM.
