3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
Thisappliesmainlytooutdoorinstallations,inareaswherehigh
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
Tomaintainthehousingprotection,makesurethatthehousinglidis
closedduringoperationandlocked,ifnecessary.

system
4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics.Todothis,lifttheterminalblockwithasmallscrewdriver
andpullitout.Whenreinsertingtheterminalblock,youshouldhearit
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable gland and remove blind
plug
3. Removeapprox.10cm(4in)ofthecablemantle(signaloutput),
strip approx. 1 cm (0.4 in) insulation from the ends of the indi-
vidual wires
4. Insert the cable into the sensor through the cable entry
Fig. 3: Connection steps 5 and 6
5. Insert the wire ends into the terminals according to the wiring plan
Information:
Solidcoresaswellasexiblecoreswithwireendsleevesareinsert-
eddirectlyintotheterminalopenings.Incaseofexiblecoreswithout
endsleeves,presstheterminalfromabovewithasmallscrewdriver,
theterminalopeningisthenfree.Whenthescrewdriverisreleased,
the terminal closes again.

6. Check the hold of the wires in the terminals by lightly pulling on
them
7. Connectthecablescreeningtotheinternalgroundterminal,con-
nect the outer ground terminal to potential equalisation in case of
power supply via low voltage
8. Connect the lead cable for voltage supply in the same way ac-
cordingtothewiringplan,inadditionconnectthegroundconduc-
tor to the inner ground terminal when powered with mains voltage.
9. Tighten the compression nut of the cable entry gland. The seal
ring must completely encircle the cable
10. Screw the housing lid back on
Theelectricalconnectionisnished.
Information:
The terminal blocks are pluggable and can be removed from the
housinginsert.Todothis,lifttheterminalblockwithasmallscrewdriv-
erandpullitout.Wheninsertingtheterminalblockagain,youshould

adjustment module
5.1 Insert display and adjustment module
The display and adjustment module can be inserted into the sensor
andremovedagainatanytime.Youcanchooseanyoneoffourdier-
ent positions - each displaced by 90°. It is not necessary to interrupt
the power supply.
Proceed as follows:
1. Unscrew the housing lid
2. Place the display and adjustment module on the electronics in the
desired position and turn it to the right until it snaps in.
3. Screw housing lid with inspection window tightly back on
Disassembly is carried out in reverse order.
Thedisplayandadjustmentmoduleispoweredbythesensor,anad-
ditional connection is not necessary.

Note:
Ifyouintendtoretrottheinstrumentwithadisplayandadjustment

inspection glass is required.
5.2 Parameter adjustment - Quick setup
Toquicklyandeasilyadaptthesensortotheapplication,selectthe
menu item " Quick setup" in the start graphic on the display and
adjustment module.
Carry out the following steps in the below sequence.

Youcannd"Extended adjustment" in the next sub-chapter.
Measurement loop name
Intherstmenuitemyouassignasuitablemeasurementloopname.
Permitted are names with max. 19 characters.
Application
Inthismenuitem,youselecttheapplication.Theselectioncomprises
process pressure and level measurement.
Information:
WithVEGABAR82Modbus,theconnectionofaslavesensorisnot
possible.The item "Secondary sensor" must therefore be set to "
Deactivate".
Units
In this menu item you determine the adjustment and temperature
units of the instrument. Depending on the selected application in the
menu item " Application",dierentadjustmentunitsareavailable.
Position correction
Inthismenuitemyoucompensatetheinuenceoftheinstallation

Thequicksetupisnished.
VEGABAR 82 always measures pressure independently of the pro-
cess variable selected in the menu item " Application".To output the
selectedprocessvariablecorrectly,anallocationoftheoutputsignal
to 0 % and 100 % must be carried out (adjustment).
With the application " Level",thehydrostaticpressure,e.g.withfull
andemptyvessel,isenteredforadjustment.Seefollowingexample:

Fig. 7: Parameter adjustment example Min./max. adjustment, level measure-
ment
1 Min. level = 0 % corresponds to 0.0 mbar
2 Max. level = 100 % corresponds to 490.5 mbar
Ifthesevaluesarenotknown,anadjustmentwithllinglevelsofe.g.
10%and90%isalsopossible.Bymeansofthesesettings,thereal
llingheightisthencalculated.
Theactualproductlevelduringthisadjustmentisnotimportant,
becausethemin./max.adjustmentisalwayscarriedoutwithout
changing the product level.These settings can be made ahead of
time without the instrument having to be installed.
5.3 Parameter adjustment - Extended adjustment
Fortechnicallydemandingmeasuringpoints,youcancarryout
extended settings in " Extended adjustment".

O = Bluetooth not active
The security concept of Bluetooth operation absolutely requires that
the default setting of the sensor PIN be changed.This prevents unau-
thorizedaccesstothesensor.
The default setting of the sensor PIN is " 0000". First of all you have
tochangethesensorPINintheadjustmentmenuofthesensor,e.g.
to " 1111":
1. Go to setup via the extended operation
2. Lock operation by changing sensor PIN
3. Enable operation again by entering the sensor PIN once more

Start PACTware and the VEGA project assistant. Select the device
search via Bluetooth and start the search function.The device auto-
matically searches for Bluetooth-capable devices in the vicinity.
The message " Instrument search running" is displayed. All devices
found are listed in the operating window.The search is automatically
continued continuously.
Select in the device list the requested device.The message " Con-
necting" is displayed.
Fortherstconnection,theoperatingdeviceandthesensormust
