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.
On instruments with one of the optional interfaces (RS232/Ethernet),
the measured values can be retrieved via modem or network and
displayed by means of a web browser,Visual VEGA or WEB-VV.It is
also possible to send measured values and messages via e-mail.The
use of VEGAMET 625 is particularly suitable for stocktaking,VMI
(Vendor Managed Inventory)and remote enquiry.
The VEGAMET 625 signal conditioning instrument can power two
HART sensors and process their measured signals via the same
cable.The measured value transmission is carried out via a digital bus
system (HART Multidrop). The requested parameter is displayed and
also sent 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 actuators are also integrated.
Wide-range power supply unit with 20 …253 V AC/DC for world-wide
use.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3Configuration
The instrument can be adjusted with the following adjustment media:
lWith integrated indicating and adjustment unit

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 instructions
The plug-in socket is designed for carrier rail mounting according to
EN 50022.The operating voltage is connected to terminals 17 and 18.
For neighbouring series 600 instruments it is possible to continue
connection L1and Ndirectly via the supplied bridges.Max.five
instruments can be connected through in this way.
Danger:
Looping through via bridges is only allowed for operating voltage
(sockets L1and N). The bridges must never be used with single
instruments,at the end of a row of instruments or with other sockets.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 may not be installed in explosion-endangered areas.
Before setup,the Ex separating chamber must be attached (as shown
below)with Ex versions.Safe operation can be only ensured if the
operating instructions manual and the EG 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 according to
the below chart.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf voltage surges are expected,install overvoltage arresters
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
The voltage supply can be 20 …253 V AC/DC,50/60 Hz.
The operating voltage of VEGAMET 625 is connected with standard
cable according to the national installation standards.
Standard two-wire cable can be used for connecting the sensors.The
screening is absolutely necessary to ensure interference-free oper-
ation with HART sensors.
Connect the cable screen on both ends to ground potential.In the
sensor,the screen must be connected directly to the internal ground
terminal.The ground terminal on the outside of the sensor housing
must be connected to the potential equalisation (low impedance).
If potential equalisation currents are expected,the screen connection
on the side of VEGAMET 625 must be made via a ceramic capacitor
(e.g.1nF,1500 V). The low frequency potential equalisation currents
are thus suppressed,but the protective effect against high frequency
interference signals remains.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2Connection procedure
Note:
Before the actual setup,each HART sensors must be assigned an
address (address range 1-15), (see chapter "Setup"). Address 0
(mode 4…20 mA)must not be used.When assigning an address,
only one sensor should be connected to VEGAMET 625.If connection
is completed already,the wiring must be briefly cancelled for
addressing.Depending on the installation location of the sensors,it
can be advantageous to carry out this addressing before installing and

connecting the sensors.This can be conveniently carried out e.g.in
the workshop.You just need a 24 Volt power supply as well as an
indicating and adjustment module PLICSCOM or the adjustment
software PACTware with VEGACONNECT.
Move on to electrical connection and proceed as follows:
1Snap the socket without VEGAMET 625 onto the carrier rail
2Connect sensor cable to terminal 1/2(active input)or 3/4(passive
input), provide a screening
3When using several sockets,loop the power supply by means of
bridges
4Connect power supply (switched off)to terminal 17 and 18
5If necessary,connect relays or other outputs
6Insert VEGAMET 625 into the plug-in socket and screw it down
tightly
Note:
If the addressing of the sensors has not yet been carried out,only one
sensor must be connected.Addressing (see chapter "Setup")of the
first sensor can then be carried out.Afterwards,the first sensor must
be disconnected again and the next sensor connected and provided
with an address.Then all sensors can be connected and setup can be
started.
Before setting up Ex versions,make sure the Ex separating chamber is
plugged on the left housing side (above the sensor terminals). The
pins for type and Ex coding must also be inserted correctly.
Information:
lOn the active input (terminal 1/2), VEGAMET 625 provides power
for the connected sensors.Power supply and measurement data
are transmitted over the same two-wire cable.This mode is
provided for connection of measuring transducers without sepa-
rate operating voltage (sensors in two-wire version).
lOn the passive input (terminals 3/4), the sensors are not supplied
with energy -only the measured value is transmitted.This input is
for instruments with their own separate operating voltage (sensors
in four-wire version or separators such as VEGATRENN 149). On
aVEGAMET 625 in Ex version,the passive input is not available
due to approval/technical reasons.
Note:
VEGAMET 625 is designed for connection of two HART sensors.
Because they are accessed via different addresses in the HART
multidrop mode,both sensors are connected to the same sensor input.
These are either terminals 1/2(active input)or terminals 3/4(passive
input). Simultaneous mixed operation on active and passive input is
not possible.The measured value transmission is carried out via the
VEGAMET 625 •Double channel HART signal conditioning instrument 13
5Connecting to power supply
28970-EN-110801

digital HART signal.An analogue 4…20 mAtransmission is not
possible.Because this is a digital bus system,only one two-wire cable
should lead to the two sensors.Adistributor can be connected directly
in front of the sensors.As an alternative,the connection to the next
sensor can be continued via the second cable entry in the sensor
housing.The addressing of the sensors should be carried out before
connection,see chapter "Set up".

The integrated indicating and adjustment unit is used for measured
value display,adjustment and diagnosis of VEGAMET 625 as well as
the connected sensors.The indication and adjustment are carried out
via four keys and a clear,graphic-capable display with background
lighting.The adjustment menu with selectable language is clearly
structured and enables easy setup.
Certain adjustment options are not possible or only partially available
with the integrated indicating and adjustment unit,e.g.settings for the
e-mail server.For such applications,the use of PACTware with
appropriate DTMs is recommended.

Note:
Approx.10 minutes after the last pressing of a key,an automatic reset
to measured value indication is triggered.Any values not confirmed
with [OK]will not be saved.
6.2Setup steps
Through parameter adjustment,the instrument is adapted to the
individual application conditions.Ameasurement loop calibration is
the most important step and should always be carried out.Ascaling of
the measured value to the desired physical variable and unit,possibly
including a linearization curve,is often useful.The adaptation of the
relay switching points or the setting of an integration time to smooth the
measured value are further standard adjustment options.
For instruments with Ethernet interface,the instrument must be
provided with an IP address and subnet mask suitable for the
instrument.As an alternative,addressing via DHCP and a host name
is also possible.If necessary,the e-mail/webserver can be also
configured with PACTware.
Information:
When using PACTware and the corresponding VEGA DTM,additional
settings can be carried out which are not possible 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 converter VEGA-
CONNECT.
Further instructions for setting up the web server and e-mail functions
are stated in the online help of PACTware or the VEGAMET 625 DTMs
as well as the supplementary instructions manual "RS232/Ethernet
connection".
VEGAMET 625 can process measured values of more than one HART
sensor.The measured values are transmitted as digital HART signals
to the same cable (bus). An analogue 4…20 mAtransmission is not
possible,the current is limited to 4mA.An own,unambiguous address
(address range 1-15)must be assigned to each connected sensor.
This mode is also called HART multidrop mode.Address 0(mode
4…20 mA)must not be used.

VEGAMET 625 •Double channel HART signal conditioning instrument 17
6Setup with the integrated indicating and adjustment unit
28970-EN-110801

Note:
When addresses are being assigned,only one sensor must be
connected on the bus.If this is not the case,no sensor can be
accessed and it is not possible to assign an address.
The addressing can be carried out directly on each HART sensor via
the respective adjustment unit or adjustment software.As an
alternative,the setting of the sensor address can be also carried out
via the VEGAMET menu under "Service -Sensor address"(see
chapter "Setup procedure"under "Service -Change sensor address").
After being switched on,VEGAMET 625 first of all carries out a short
self-check.The following steps are carried out:
lInternal check of the electronics
lindication of the instrument type,firmware version as well as the
instrument TAG (instrument name)
lThe output signals jump briefly to the set fault value
After the assignment of the addresses to the sensors,the current
measured values will be displayed and outputted.
As requested,the measured value display shows the individual
measurement loops separately or in a joint overview.The respective
digital display value,the measurement loop name (meas.loop TAG)
and the unit are shown.With the separate presentation,an analogue
bar graph is also displayed and the measured values appear in bigger
font size.By pushing the [>]key,you move between the different
indicating options.
Note:
Depending on the configuration and use of all measurement loops,the
cycle time for the measured value transmission can take up to five
seconds.
By pushing [OK]you move from the measured value indication to the
main menu.

àSelect the menu item "Device settings"with [->]and confirm with
[OK].
Under the menu item "Device settings",you can select the requested
application.For all level,gauge and differential measurements,the
application "Standard"is correct.
If an interface measurement should be carried out with a VEGAFLEX
67,you have to choose the menu item "Interface measurement"as
application.After the configuration of the inputs,the exact DK value for
the upper medium must be entered.For further information see
chapter "Application examples".
àSelect the requested application with [->]and save your setting
with [OK].Finally change to the menu item "Input"with [->].
Because VEGAMET 625 has two inputs,the measurement loops must
be assigned to the inputs.After the addresses of the HART sensors
are assigned,a list of the existing sensors can be prepared and
displayed via "Sensor selection -Sensor search".Now you can assign
the requested sensor to each measurement loop.
For transmission,VEGAMET 625 must be informed which "Sensor
value"should be used for further processing.Depending on the sensor
type this can be distance,pressure,interface or temperature.You will
find further information under the menu item "Meas.loop -Input".
àAllocate the requested inputs to the appropriate measurement
loops,select the suitable sensor value and save your settings with

[OK].After the first setup,you can modify the inputs also under
"Meas.loop -Input".
You can assign an unambiguous name to VEGAMET 625 via the
Device-TAG.This function is recommended when several instruments
are implemented and a good documentation of larger systems is
required.
àEnter the requested values via the appropriate keys and save your
settings with [OK].
For instruments with integrated Ethernet interface,the instrument must
be provided with an IP address/Subnet mask suitable for your network.
Depending on the network,a gateway address may also be required.
As an alternative,addressing via DHCP and a host name is also
possible.These data are available from your network administrator.
Keep in mind that your settings are only effective after a restart of
VEGAMET 625.Further information on these network parameters is
available in the supplementary instructions manual "RS232/Ethernet
connection"and in the online help of the corresponding DTMs.
Carry out your settings via the appropriate keys and save with [OK].
àCarry out your settings via the appropriate keys and save with
[OK].Disconnect briefly the operating voltage so that the modified
settings become effective.
