3.2 Principle of operation

VEGACONNECT 3 is an interface converter for connecting
communication-capable VEGA instruments to the RS232
interface of a PC or modem. It can be also used as universal
HART modem for sensors of other manufacturers. For
parameter adjustment of these instruments, an adjustment
software such as PACTware™ with VEGA DTM or VEGA
Visual Operating (VVO) is required. The Visual VEGA software
can be used for remote enquiry of measured values.

VEGACONNECT 3 can be connected to the VEGA instru­ments listed below. All currently available protocol versions are
supported. These are: HART, Profibus PA, Foundation
Fieldbus, VBUS (optional).

l VEGAPULS radar

sensors

l VEGASON ultrasonic sensors
l VEGAFLEX guided microwave
l VEGABAR process pressure

transmitter

l Pressure transmitter D series
l Capacitive electrode EL/EK
l VEGADIS indicating instruments
l VEGAMET signal conditioning

instruments

VEGACONNECT 3 is available in two versions:

l CONNECT3.X: Standard version without VBUS int

erface

l CONNECT3.V: Version with additional VBUS interface

Two adapters and terminals for connection to different instru­ment series are attached to each VEGACONNECT 3.

The VEGACONNECT 3 interface converter is connected via
an RS232 connection to a PC or an external modem. It
converts the signals and protocols of the RS232 interface into
the corresponding signal/protocol of the connected instrument.
The following systems are supported:

l 4 … 20 mA with

superimposed HART protocol

l Profibus PA via I²C protocol
l Foundation Fieldbus

via I²C protocol

l VBUS (only with the opt

ion additional VBUS interface)

Power supply is provided via the control cables of the RS232
interface of the PC or modem. In a few cases, it may happen
that the gauges of the control cables are not sufficient for
power supply of VEGACONNECT 3. In this case, power
supply can be carried out via a standard, separate power
supply unit (e.g. Friwo EP1). A protective low voltage in the

Area of application

Functional principle

Supply

range of 6 … 12 V DC is not necessary. The power supply unit
is connected with a low voltage micro plug (outer ø 3.5 mm,
inner ø 1.3 mm) to VEGACONNECT 3. The polarity is
unimportant.

You can find detailed specifications on voltage supply in
chapter "Technical data" in the "Supplement".

3.3 Operation

The adjustment is carried out via a Windows PC with a
parameter adjustment software such as PACTware™ with
VEGA DTM or VVO. There are no adjustment elements on the
instrument itself.

3.4 Packaging, transport and storage

Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.

The packaging of standard instruments consists of environ-

ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.

Transport must be carried out under consideration of the notes
on the transport packaging. Nonobservance of these instruc­tions can cause damage to the device.

The delivery must be checked for completeness and possible
transit damage immediately at receipt. Ascertained transit
damage or concealed defects must be appropriately dealt
with.

Up to the time of installation, the packages must be left closed
and stored according to the orientation and storage markings
on the outside.

Unless otherwise indicated, the packages must be stored only
under the following conditions:

l Not

in the open

l Dry and dust free
l Not exposed to corrosive media
l Protected against

solar radiation

l Avoiding mechanical shock and vibration

4 Connection

4.1 Connection to P

C/Modem

For connection of VEGACONNECT 3 to a PC or a modem, an
RS232 interface is absolutely necessary. If your PC has no
RS232 interface, you can use an USB-RS232 adapter (order

number 2.26900). The voltage supply of VEGACONNECT 3 is
carried out via the control cables of the RS232 interface. If
these do not deliver suffiencient power, an additional power
supply unit can be used (see chapter "Configuration - Power

supply").

VEGACONNECT 3 can be connected with the 9-pole Sub-D
plug directly to the RS232 interface of any PC.

If VEGACONNECT 3 should be connected with the RS232
interface of an external modem, a special modem connection
cable must be used in addition. The cable is available from
VEGA under the order number "MODEM.KX". Alternatively,

adapter 9/25-pole for modems with 25-pole connection.

4.2 Connection of the sensor/signal conditioning

instrument

VEGACONNECT 3 can be connected to all communication-
capable VEGA instruments. Because there are many different
instrument series and protocol versions, the connection
possibilities are manifold. The supplied adapter enables
connection to each instrument.

Note:

Communication with the sensor is carried out with VEGAMET

624/625 and VEGASCAN 693 also via the front I²C interface of
the signal conditioning instrument. The connection of VEGA-
CONNECT 3 directly to the 4 … 20 mA sensor cable is not
possible.

5.2 Connection via HART

If the resistance of the connected processing system is less
than 230 Ohm, the digital adjustment signal is extremely
damped or short-circuited. Digital communication with the PC
is then no longer possible. With low impedance processing
systems, a resistance of approx. 230 Ohm must be integrated
into the 4 … 20 mA connection cable. The connection can be
either carried out in parallel to the sensor or via the resistor.
