You have connected the PC with the adjust-
ment software VVO to your measuring sys-
tem.
• Now switch on the power supply of the
connected sensor.
In the first 10 … 15 seconds the sensor start to
draw a current of approx. 22 mA (selftest) and
takes then a level proportional or distance-
proportional current of 4 … 20 mA.
• Start the adjustment software VVO on your
PC.
• In the entrance window you choose with
the arrow keys or the mouse the item "Plan-
ning“ and click to "OK“.
You should choose
"Planning“, only if you
are authorised to modify instrument param-
eters. Otherwise choose
"Operator“ or
"Maintenance“.
In the window
"User identification“ you are
asked for the name and the password.
• For setup ( planning) you enter under
name: "VEGA“ and under password also:
"VEGA“. It does not matter if the adjustment
is made in small or capital letters.
VVO determines then automatically the type
of the connected sensor and indicates a
moment later with which sensor the connec-
tion exists.
If you get no communication with the sensor,
check the following:
- The supply voltage must be at least 20 V
(four-wire sensor). Two-wire sensor: 15 V
at 4 mA or 14 V at 22 mA.
- In case VEGACONNECT 2 is directly con-
nected to the sensor cable, the load resist-
ance must be 250 … 350 Ohm.
- You have to use a VEGACONNECT 2.
Older versions of VEGACONNECT are not
compatible.
Further information on the adjustment with the
PC and the adjustment software VVO you will
find in the operating instructions of the ad-
justment software VEGA Visual Operating
(VVO).
4.3 Adjustment with the PC
Connection
The PC with the adjustment program VVO
(VEGA Visual Operating from version 2.50)
can be connected to the
- sensor
- signal cable.
PC on the sensor
For connection of the PC to the sensor, the
interface converter VEGACONNECT 2 is
required, which has to be plugged into the
provided CONNECT socket in the sensor.
PC on the signal cable
Connect the two-wire cable of
VEGACONNECT 2 to the signal cable (four-
wire sensor) or the supply cable (two-wire
sensor) of the sensor. If the resistance of the
systems (PLC, current source etc.) con-
nected to the signal/supply cable is less than
250
W, a resistor of 250 … 350 W must be
connected to the signal/supply cable during
adjustment. The digital signals modulated to
the signal cable would be considerably
damped (short circuited) through insufficient
resistance, and communication with the PC
would not be ensured.
