VEGA VEGAPULS 81 - Manual (Page 55)

VEGAPULS 64 and 81 55
Note
A digital adjustment signal is superimposed to
the 0 … 20 mA signal output. Is the inner
resistor of the connected signal conditioning
instrument is less than 100 Ω (e.g. with an
indicating instrument), the digital adjustment
signal is considerably damped. In this case
loop a load resistor R ≥ 100 Ω into the signal
line to avoid the low impedance damping
during the adjustment.
Adjustment
The PC with the adjustment software VVO is
connected to the measuring system.
The individual adjustment and input steps are
described in the following (e.g. • choose…; •
Start…).
• Switch on the power supply of the con-
nected radar sensor.
• Switch on the power supply of the con-
nected signal conditioning instrument.
• Start your PC and the adjustment software
VVO.
• In the entrance screen choose with the shift
keys or with the mouse the point “ Planning“
and push “ OK“. The identification is en-
quired.
Set-up
6.2 Adjustment with PC
Connection
In the chapter “2.3 Configuration of measuring
systems“ the connection of the PC is shown in
different co-ordinations. The PC with the ad-
justment program VVO (VEGA Visual Operat-
ing) can be connected to the:
- sensor
- signal line
- signal conditioning instrument VEGAMET
514 V or 515 V
- processing system VEGALOG
Connection of the PC to a sensor
For connection of the PC to a sensor,
VEGACONNECT interface converter is re-
quired. Plug the VEGACONNECT into the
standard connection of the PC and connect
the two-wire line of VEGACONNECT either to
the signal output on the sensor (VEGAPULS
81) or (for instruments of VEGAPULS 64 se-
ries) to the provided CONNECT-socket in the
sensor.
Connection of the PC to a signal line
Connect the two-wire line of VEGACONNECT
to the signal output line of the sensors.
Connection of the PC to the signal condi-
tioning instrument VEGAMET
Plug the two-wire line of VEGACONNECT into
the CONNECT-sockets on the signal condition-
ing instrument.
Connection of the PC to the processing
system VEGALOG
Connect the PC with the processing system
VEGALOG 571 via a standard computer cable.
• Enter under the name “ VEGA“.
• Enter under the password “ VEGA“.
This is the pre-adjusted identification.
