3.2Principle of operation
VEGATOR 631 Ex is a single signal conditioning instrument for
processing the signals of conductive probes.
The VEGATOR 631 Ex signal conditioning instrument powers
connected sensors and simultaneously processes their measuring
signals.
When the medium reaches the switching point of the sensor,the
voltage between sensor and VEGATOR 631 Ex drops.The output
relays then switch according to the set mode.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3Operation
The integration time and the mode (A/B)can be preset via a DIL switch
block on the signal conditioning instrument.
Apotentiometer for adjustment the switching point is located on the
front panel of VEGATOR 631 Ex.
3.4Packaging,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 environment-
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.

4Mounting
4.1General instructions
VEGATOR 631 Ex signal conditioning instrument with plug-in socket
for mounting on carrier rail according to EN 50022.
The front plate of VEGATOR 631 Ex can be provided with a lead-
sealable transparent cover to protect the instrument against unau-
thorised or inadvertent adjustment.See the following figure on how to
remove the transparent cover.
Fig.2:Removing the transparent cover
For moisture-protected mounting outside the switching cabinet,we
offer an insulated protective housing with transparent cover (IP 65)for
surface mounting.
In this housing you can mount a maximum of 3instruments of 36 mm
width.
4.2Mounting instructions
The plug-in socket is constructed for carrier rail mounting according to
EN 50022.Power supply is connected to terminals 9and 10.For
neighbouring signal conditioning instruments,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 VEGATOR 631 Ex in Ex version is an auxiliary,intrinsically safe
instrument and must 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.VEGATOR 631 Ex must not be opened.
Close the upper terminals according to the following illustration.

Fig.3:Mounting the separating chamber
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 VEGATOR631 Ex 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 overvoltage surges are expected,overvoltage arresters should
be installed
Tip:
We recommend VEGA overvoltage arresters B61-300 (power supply
VEGATOR 631 Ex)and B62-36G(sensor supply).
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the sensors
and power supply units.
The power supply can be 20 …253 V AC,50/60 Hz or 20 …72 V DC.
Power supply of VEGATOR 631 Ex is connected with standard cable
according to the national installation standards.
The sensors are connected with standard two-wire cable without
screen.If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas,screened cable should be
used.
From a cable length of 50 m use one cable for each signal conditioning
instrument.
If you are using a common cable,the min.and max.cables must be
screened.The screen must be connected the ground on both sides.
Take note of the corresponding installation regulations for Ex
applications.
5.2Connection procedure
Move on to electrical connection and proceed as follows:
1Snap the socket without VEGATOR 631 Ex onto the carrier rail
2Connect the sensor cable to terminal 1and 3(see the following
wiring plans)
3Connect power supply (switched off)to terminal 9and 10
4Insert VEGATOR 631 Ex into the plug-in socket and screw it down
tightly
The electrical connection is finished.

Apotentiometer for switching point adaptation is located on the front
plate of the signal conditioning instrument.With this potentiometer you
can adapt the measuring system to the conductivity of the product.
On top to the side (covered when mounted)there is a DIL switch block
with four switches.The individual switches are assigned as follows:
l1-A/Bmode
-A-Max.detection or overflow protection
-B-Min.detection or dry run detection
l2-Integration time 2s
l3-Integration time 6s
