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.

4 Connecting to power supply
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. Ifadisplayandadjustmentmoduleisinstalled,removeitbyturn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

5.2 Parameter adjustment
AparameterchangewithSILqualiedinstrumentsmustalwaysbe
carried out as follows:
• Unlock adjustment
• Change parameters
• Lockadjustmentandverifymodiedparameters
Thisensuresthatallmodiedparametershavebeendeliberately
changed.
Unlock adjustment
The instrument is shipped in locked condition.
Topreventunintentionalorunauthorizedadjustment,theinstrument
is protected (locked) against all parameter changes while in normal
operating condition.
For each parameter change you have to enter the PIN of the instru-
ment.Indeliverystatus,thePINis"0000".
Change parameters
Youcanndadescriptionbelowtherespectiveparameter.

Lock adjustment and verify modied parameters
Youcanndadescriptionbelowtheparameter"Setup - Lock adjust-
ment".
1. Go to the menu " Setup" via the display and adjustment module.
2. In this menu item you activate/deactivate the slave sensor for
electronicdierentialpressureandselecttheapplication,e.g.
level
3. Select in the menu item " Units" the adjustment unit of the instru-
ment,e.g."bar".
4. Dependingontheapplication,carryouttheadjustmente.g.inthe
menu items " Min. adjustment" and " Max. adjustment".
VEGABAR 86 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:

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.
With this menu item you safeguard the sensor parameters against
unauthorizedorunintentionalmodications.
Todetectparameterizationerrorsreliably,safety-relevantparameters
mustbeveriedbeforesavingthemintotheinstrument.
1. Enter PIN
Indeliverystatus,thePINis"0000".
2. Character string comparison
You then have to carry out the character string comparison. This is
used to check the character presentation.
3. Serial number acknowledgement
Afterwardsyouconrmthattheserialnumberofyourinstrumentwas
carried over correctly. This is used to check device communication.
4. Verify parameters
Conrmthemodiedvaluesoneaftertheother.
If the described process of parameter adjustment was run through
completelyandcorrectly,theinstrumentwillbelockedandhence
ready for operation.

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

cess(authentication)withBluetooth,thechangedPINisstilleective.
Note:
Bluetooth access can only be established if the current sensor PIN
diersfromthedefaultsetting"0000". It is possible both when the
adjustment is unlocked and when it is locked.
6.2 Connecting
Smartphone/Tablet
Start the adjustment app and select the function "Setup". The smart-
phone/tablet searches automatically for Bluetooth-capable instru-
ments in the area.
PC/Notebook
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
authenticateeachother.Aftersuccessfulauthentication,thenextcon-
nection functions without authentication.
