3.2 Principle of operation

Area of application
VEGATRENN 149A Ex is an [EEx ia] separator
with separate power supply for connection of
4 ... 20 mA/HART sensors in two-wire version. As
corresponding electrical equipment, it ensures a
galvanic separation between sensor circuit and
processing circuit and thus between Ex and non-Ex
area.

Functional principle
An integrated transmitter power supply powers the
connected sensor. The clamp voltage from the
sensor (4 ... 20 mA) is transferred linear and
galvanically separated to the output. The HART
communication sockets in the front ensure a
bidirectional transmission of HART signals.
Supply
Weitbereichnetzteil mit 20 ... 250 V AC/DC zum
weltweiten Einsatz.
You can find detailed information on the power
supply in chapter "Technical data" in the "Supple-
ment".
3.3 Operation
There are no adjustment elements on VEGA-
TRENN 149A Ex. A parameter adjustment of the
connected sensors can be carried out via the
HART communication sockets. The adjustment of
the connected sensors is carried out preferrably via
a Windows PC with a parameter adjustment
software such as PACTware™ and respective
DTM.

3.4 Storage and transport

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