1.1 Authorised personnel
All operations described in this documentation must be carried out
onlybytrained,qualiedpersonnelauthorisedbytheplantoperator.
Duringworkonandwiththedevice,therequiredpersonalprotective
equipment must always be worn.
1.2 Appropriate use
Model VEGABAR 87 is a pressure transmitter for level and gauge
measurement.
Youcannddetailedinformationabouttheareaofapplicationin
chapter "Product description".
Operational reliability is ensured only if the instrument is properly
usedaccordingtothespecicationsintheoperatinginstructions

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
• Whenmountinghorizontally,turnthehousingsothatthecable
gland or plug connector point downward
• 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.
Tomaintainthehousingprotection,makesurethatthehousinglid
is closed during operation and depending on the housing version
locked,ifnecessary.
Makesurethatthedegreeofcontaminationspeciedinchapter
"Technical data" meets the existing ambient conditions.

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

5 Set up the sensor with the display and
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.
1. Measurement loop name
Intherstmenuitemyouassignasuitablemeasurementloopname.
Permitted are names with max. 19 characters.
2. Application
Inthismenuitem,youselecttheapplication.Theselectioncomprises
process pressure and level measurement.
Information:
WithVEGABAR87Modbus,theconnectionofaslavesensorisnot
possible.The item "Slave sensor" must therefore be set to "Deacti-
vate".
3. 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.
4. Position correction
Inthismenuitemyoucompensatetheinuenceoftheinstallation
positionoftheinstrument(oset)onthemeasuredvalue.
5. Zero adjustment
Inthismenuitemyoucarryoutthezeroadjustmentfortheprocess
pressure.
Enter the corresponding pressure value for 0 %.
6. Span adjustment
In this menu item you carry out the span adjustment for the process
pressure
Enter the corresponding pressure value for 100 %.
4. Position correction
Inthismenuitemyoucompensatetheinuenceoftheinstallation
positionoftheinstrument(oset)onthemeasuredvalue.
5. Max. adjustment
In this menu item you carry out the max. adjustment for level
Enter the percentage value and the corresponding value for the max.

Thequicksetupisnished.
VEGABAR 87 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).
Duringadjustment,thepressureisenterede.g.forthelevelwithfull
andemptyvessel,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 196.2 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realproductlevelduringthe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".
