and operation in Ex areas.These safety instructions are part of
the operating instructions manual and come with the Ex-
approved instruments.
2.7Environmental instructions
Protection of the environment is one of our most important
duties.That is why we have introduced an environment
management system with the goal of continuously improving
company environmental protection.The environment man-
agement system is certified acc.to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the environ-
mental instructions in this manual:

3.2Principle of operation
VEGAMET 625 is a universal signal conditioning instrument for
a number of applications such as level,gauge,interface and
process pressure measurement.At the same time,it can serve
as power supply unit for connected sensors.VEGAMET 625 is
designed for connection of two independent VEGA HART
sensors.Hence two independent measurements can be
carried out.By means of a third measurement loop,the
difference between the two input values can be calculated.
With instruments with an optional interface (RS232/Ethernet)
the measured values can be retrieved via modem or network
and displayed by means of a web browser or Visual VEGA.Itis
also possible to send measured values and messages via e-
mail.
The VEGAMET 625 signal conditioning instrument can power
connected sensors and process their measured signals.The
requested parameter is displayed and outputted in addition to
the integrated current outputs for further processing.Hence
the measured signal can be transferred to a remote indication
or a superordinate control system.Three level relays for
control of pumps or other actors are also integrated.
Wide-range power supply unit with 20 …253 VAC/DC for
world-wide use.
You can find detailed information on the power supply in the
"Technical data"in the "Supplement".
3.3Adjustment
VEGAMET 625 can be adjusted with the following adjustment
media:
lthe integrated indicating and adjustment unit
lan adjustment software acc.to FDT/DTM standard,e.g.
PACTware™and a Windows PC
The entered parameters are generally saved in VEGAMET
625,when operated with PACTware™optionally also on the
PC.
Information:
When using PACTware™and corresponding VEGA DTM,
additional settings can be carried out which are not or only
partly possible with the integrated indicating and adjustment

unit.When using an adjustment software,you either need one
of the integrated interfaces (RS232/Ethernet)or the interface
converted VEGACONNECT.
Further instructions for setting up the web server and e-mail
functions are stated in the online help of PACTware™or the
VEGAMET 625 DTM as well as the operating instructions
manual "RS232/Ethernet connection".
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc.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.

4Mounting
4.1General instructions
Each series 600 instrument consists of the actual signal
conditioning instrument as well as a plug-in socket for carrier
rail mounting.Because it has protection class IP 30 or IP 20,
the instrument is intended to be used in switching cabinets.
4.2Mounting information
The plug-in socket is constructed for carrier rail mounting acc.
to EN 50022.Power supply is connected to terminals 17 and
18.For neighbouring series 600 signal conditioning instru-
ments,it is possible to continue connection L1and Ndirectly
via the supplied bridges.
Danger:
The bridges must never be used with single instruments or at
the end of a row of instruments.If this rule is not heeded,there
is a danger of coming into contact with the operating voltage or
causing a short circuit.
A VEGAMET 625 in Ex version is an auxiliary,intrinsically safe
instrument and must not be installed in hazardous areas.
Before setup,the Ex separating chamber must be attached (as
shown below)with Ex versions.Safe operation can be ensured
only if the operating instructions manual and the EU type
approval certificate are observed.VEGAMET 625 must not be
opened.
All signal conditioning instruments are provided with different
gaps dependent on type and version (mechanical coding).
The plug-in socket is provided with coded pins that can be
inserted to prevent accidental interchanging of the various
instrument types.
With a VEGAMET 625 in Ex version,the supplied coded pins
(type coded pin and Ex coded pin)must be inserted by the
user acc.to the below chart.
