The process pressure acts on the sensor element via the stainless
steel diaphragm.The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted
as measured value.1)
4 … 20 mA two-wire electronics for voltage supply and measured
value transmission on the same cable.
3.3 Operation
The VEGABAR 17 has no adjustment options.
However,therearetwobuilt-inpotentiometersforrecalibrationofzero
and span.
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
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 in due 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 con-
cealed 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.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
• Relative humidity 20 … 85 %

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
processtting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.
Youcanndthespecicationsinchapter"Technical data" and on the
nameplate.
Toprotectthediaphragm,theprocessttingiscoveredbyaprotec-
tive cap.
Remove the protective cap just before installation so that the dia-
phragm will not get damaged. It is recommended to keep the cap and
use it again later for storage or transport.
4.2 Mounting instructions
Pleasecheckthediaphragmvisuallyfordamageandleakinguid
before mounting and setting up the instrument. Make sure that the
diaphragm doesn't get damaged during installation.
Caution:
Theinstrumentmayonlybeusedifitisinatechnicallyawlesscondi-
tion and has an undamaged diaphragm.
VEGABAR 17 functions in any installation position. It is mounted ac-
cording to the same directives as a manometer (DIN EN 839-2).
Information:
Werecommendusinglockttings,measuringinstrumentholdersand
siphons from our line of accessories.
4.3 Installation procedure
FormountingVEGABAR17,aweldedsocketisrequired.Youcannd
these components in the supplementary instructions manual "Welded
socket and seals".
Usethesealttingtotheinstrument,orincaseofNPTconnections,a
high-resistance sealing material.
Screw VEGABAR 17 into the welded socket with a wrench applied to
thehexagonoftheprocesstting.Forthepropertorqueseechapter
"Technical data",forspannersizeseechapter"Dimensions".

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed.
Tip:
We recommend VEGA overvoltage arrester ÜSB 62-36G.X.
Inhazardousareasyoumusttakenoteoftherespectiveregulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
The supply voltage and the current signal are carried on the same
two-wire connection cable.
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1.
VEGA power supply units VEGATRENN 149AEx, VEGASTAB 690,
VEGADIS 371 as well as all VEGAMETs meet this requirement.When
using one of these instruments, protection class III is ensured for
VEGABAR 17.
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Output voltage of the power supply unit can be lower under nomi-
nal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
chapter "Technical data")
The instrument is 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.
Use cable with round cross-section. A suitable cable outer diameter
of (see chapter "Technical data")ensuresthesealeectofthecable
gland.Ifyouareusingcablewithadierentdiameterorcross-sec-
tion, exchange the seal or use a suitable cable gland.
For the version with round plug connector M12 x 1, a suitable, ready-
made connection cable (article no. ASL.1S.) in 5 m, 10 m or 25 m
lengths is available from the line of VEGA accessories.
If screened cable is required, connect the cable screen on both ends
to ground potential.
In Ex systems, the grounding is carried out according to the installa-
tion regulations.
In electroplating and CCP systems (cathodic corrosion protection) it
mustbetakenintoaccountthatsignicantpotentialdierencesexist.

This can lead to unacceptably high currents in the cable screen if it is
grounded at both ends.
Information:
Themetallicpartsoftheinstrument(processtting,housing,etc.)are
conductively connected to the ground terminal.

6.1 Setup steps
After mounting and electrical connection, VEGABAR 17 is ready for
operation.
VEGABAR 17 delivers a current of 4 … 20 mA corresponding to the
actual process pressure.
Further settings are not necessary.
6.2 Recalibration
Withbothinstrumentswiththreadringorterminalhousing,zeroand
span can be adjusted via integrated potentiometers. Adjustment
range:
• Zero ± 5 %
• Span ± 5 %
This allows, for example, the consideration of an installation position
dierentfromthereferenceinstallationposition.
Ashiftingofzeroshiftsspanalsorespectively.
Note:
The potentiometer for span should only be used if you have adequate
calibration equipment (at least 3 times more precise than the devia-
tion of VEGABAR 17).
Recommended recalibration cycle: 1 year.
Proceed as follows:
1. Loosen the plug connector and screw the screwed ring in con-
nected status
2. Place the plug connector onto the instrument place and pull both
carefully out of the instrument

7 Maintenanceandfaultrectication
7.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
7.2 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
VEGABAR17oersmaximumreliability.Nevertheless,faultscanoc-
cur during operation.These may be caused by the following, e.g.:
• Sensor
• Process
• Voltage supply
• Signal processing
Therstmeasuretotakeistochecktheoutputsignal.Inmanycases,
thecausescanbedeterminedthiswayandthefaultsquicklyrectied.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. [phone].
Thehotlineismanned7daysaweekround-the-clock.Sinceweoer
this service worldwide, the support is only available in the English
language.The service is free, only standard call charges are incurred.
