For connection of a PC to a signal
conditioning instrument you require the
interface adapter VEGACONNECT 2. The PC
communicates via the interface adapter
VEGACONNECT 2 with the signal
conditioning instrument and the sensor.
Hence a digital adjustment signal is
superimposed to the signal and supply line
between sensor and signal conditioning
instrument. In chapter "2.2 Configuration of
measuring systems" the connection of the PC
in different coordinations is shown.
In any case you are requested to enter or
enquire something, this is marked in the

Set-up - Adjustment structure
Configuration Configuration Configuration Configuration Configuration means to coordinate or
determine once. In the menu Configuration
the signal conditioning instrument is informed
about the general configuration:
- which kind of sensor is connected (radar,
ultrasonic, process pressure…),
- what kind of parameter or application is
concerned (level, gauge, distance…)
- to which input the sensor is connected
- which outputs (current, voltage, relay, fault
signals, indication…) should be
coordinated to which input in which way
(inverted, threshold value controlled…).
After these adjustments (configuration) had
been carried out, the meas. system goes to
operating condition and the signal
conditioning instrument will display a
measured value. Now the sensor parameter
adjustment (adjustment, unit, linearisation
curve, sensor adaption…) can be carried
out.
Parameter adjustment Parameter adjustment Parameter adjustment Parameter adjustment Parameter adjustment means to enter values.
Parameters are entered in the signal
conditioning instrument as well as in the
connected sensors. For example:
- Min. and max. adjustment
- Meas. range limits
- Physical unit, decimal point
- Linearisation curves
- Integration time
- Meas. environment (solid, liquid,
foam generation, operating range…)
- False echo memory
- Inversion of the measured value etc.
Now all required adjustments for a precisely
adapted sensor are carried out for a reliable
measurement.
After approx. 1…2 minutes (selfcheck) the
meas. system is generally ready for
operation and indicates measured values or
a failure.
• Connect the standard plug of
VEGACONNECT 2 (9-pole) with the
interface COM 1 or COM 2 of your PC.
• Plug the two small pin plugs of
VEGACONNECT 2 into the CONNECT-
socket of the signal conditioning
instrument.
• Now switch on the voltage supply of the
signal conditioning instrument.
