VEGA VEGAFLEX 52V - Manual (Page 28)

28 VEGAFLEX 51V and 52V
When you have connected the PC with the
operating software VVO to your measuring
system,
•
switch on the power supply of the con-
nected sensor.
In the first 10 … 15 seconds the sensor takes a
current of approx. 22 mA (self check) and
takes then a level proportional or distance
proportional current.
•
Start the adjustment software VVO
(VEGA Visual Operating) on your PC.
• In the entrance window you choose with
the arrow keys or the mouse the point
Planning and click to OK.
You should only choose
Planning, when
you are entitled to modify instrument
parameters. Otherwise choose
Operator
or Maintenance.
In the window User identification you are
asked for the name and the password.
• For set-up ( planning) enter under name:
VEGA and under password also: VEGA.
It does not matter if you use capital or
small letters.
VVO determines automatically the type of the
connected sensor and shows shortly with
which sensor a connection exists.
When you get no sensor connection, check
the following:
-
The supply voltage should be at least
20 V.
- When connecting VEGACONNECT 2
directly to the sensor line, the load resis-
tor should be 250 … 350 Ohm.
- You have to use a VEGACONNECT 2.
Older versions of VEGACONNECT are
not compatible.
Further information on the adjustment with PC
and the adjustment software VVO is stated in
the operating instruction of the adjustment
software VEGA Visual Operating (VVO).
4.3 Adjustment with PC
Connection
The PC with the adjustment program VVO
(VEGA Visual Operating from version 2.50)
can be connected
-
to the sensor or
- to the signal line.
PC on the sensor
For connection of the PC to the sensor you
require the interface adapter VEGACON-
NECT 2. Insert VEGACONNECT 2 into the
provided CONNECT-sockets in the sensor.
PC on the signal line
Connect the two-wire line of VEGACONNECT
2 to the signal or supply line 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 resistor of
250 … 350
Ω
should be looped into the si-
gnal/supply line during adjustment.
The digital signals modulated to the signal
line would be extremely damped via the low
system resistors (i.e. short-circuited) so that
the communication with the PC would be
interfered.
