VEGA VEGAPULS 45 VBUS - Manual (Page 46)

46 VEGAPULS 42, 44 and 45 – VBUS
Change COM port
In the menu " Configuration/Program/Commu-
nication" you can set the interface parameters
of your PC or change the used COM port.
Configuration
Adjustment with the PC on the signal conditioning instrument
No matter whether you set up a measuring
system (consisting of sensor and VEGAMET
signal conditioning instrument or VEGALOG
processing system) with the adjustment
software VVO or with the signal conditioning
instrument, the adjustment procedure is
always the same:
- first of all in the menu "
Configuration", you
create a measurement loop
- then configure a measurement loop
- in the menu "
Instrument data" you carry out
the parameter adjustment of the sensor.
Configuration
The term "Configuration" means the basic
adjustments of VEGAMET. You inform
VEGAMET about the application (level meas-
urement, gauge, distance …), the measure-
ment loop name and the input channel. The
configuration represents an electronic wiring
and labelling of your VEGAMET or, in other
words, telling the system which sensor for
what application and where.
Parameter adjustment
After the configuration, you carry out the
parameter adjustment for each individual
sensor. This means adjusting the sensors to
the respective operating range and adapting
them to the specific application. You inform
the sensor which product distance (which
level) is "empty" and which "full". This is called
adjustment. Here you choose which physical
quantity (volume, mass) and unit of
measurement (m
3 , gal, liters …) the adjusted
measured value should be outputted in. In
the submenu "Sensor optimisation", you
inform the sensor electronics about the actual
environment, such as e.g. quick changes of
the measured value, foam generation, gas
stratification, solid or liquid.
During the setup of the measuring system
you are confronted with two terms: "Configu-
ration" and "Parameter adjustment". The
meas. system is first set up with a configura-
tion and then with a parameter adjustment.
Note:
The signal conditioning instruments are
shipped with the sensor configuration you
ordered with the signal conditioning instru-
ment.
Generally, you will use a preconfigured signal
conditioning instrument. In the following menu
"
Configuration", there are normally no adjust-
ments necessary and you can continue di-
rectly with the menu "
Parameter adjustment".
If your signal conditioning instruments are not
preconfigured, start now with the section
"
Configuration" and then continue with the
adjustments in section " Parameter adjust-
ment".
