1 For your safety
1.1 Authorised personnel
All operations described in this operating instructions manual must
be carried out only by trained specialist 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
The VEGABAR 81 is a pressure transmitter for process pressure and
hydrostatic level measurement. Due to the integrated accumulator the
instrument is particularly suitable as a portable measuring system or
test sensor for special applications.
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
manual as well as possible supplementary instructions.
1.3 Warning about incorrect use
Inappropriate or incorrect use of the instrument can give rise to
application-specichazards,e.g.vesseloverllordamagetosystem
components through incorrect mounting or adjustment. Also the pro-
tectivecharacteristicsoftheinstrumentcanbeinuenced.
1.4 General safety instructions
This is a high-tech instrument requiring the strict observance of stand-
ard regulations and guidelines. The user must take note of the safety
instructionsinthisoperatinginstructionsmanual,thecountry-specic
installation standards as well as all prevailing safety regulations and
accident prevention rules.
Theinstrumentmustonlybeoperatedinatechnicallyawlessand
reliable condition.The operator is responsible for trouble-free opera-
tion of the instrument.
Duringtheentiredurationofuse,theuserisobligedtodeterminethe
compliance of the necessary occupational safety measures with the
current valid rules and regulations and also take note of new regula-
tions.
1.5 CE conformity
ThedevicefulllsthelegalrequirementsoftheapplicableECguide-
lines.ByaxingtheCEmarking,weconrmsuccessfultestingofthe
product.

1.6 Permissible process pressure
Thepermissibleprocesspressureisspeciedonthetypelabelwith
"Processpressure",seechapter"Conguration".Forsafetyreasons,
this range may not be exceeded. This applies even if a measuring cell
with a measuring range (order-related) higher than the permissible
pressurerangeoftheprocessttingisinstalled.
1.7 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany.The published NAMUR recommendations are
acceptedasthestandardineldinstrumentation.
ThedevicefulllstherequirementsofthefollowingNAMURrecom-
mendations:
• NE 21 – Electromagnetic compatibility of equipment
• NE 43 – Signal level for malfunction information from measuring
transducers
• NE53–Compatibilityofelddevicesanddisplay/adjustment
components
• NE107–Self-monitoringanddiagnosisofelddevices
For further information see www.namur.de.
1.8 Environmental instructions
Protection of the environment is one of our most important duties.
That is why we have introduced an environment management system
with the goal of continuously improving company environmental pro-
tection.Theenvironmentmanagementsystemiscertiedaccording
to DIN EN ISO 14001.
Pleasehelpusfulllthisobligationbyobservingtheenvironmental
instructions in this manual:
• Chapter "Packaging, transport and storage"
• Chapter "Disposal"

3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• Whenmountinghorizontally,turnthehousingsothatthecable
gland points downward
• Loop the connection cable downward in front of the cable gland
Thisappliesmainlytooutdoorinstallations,inareaswherehumidityis
expected (e.g. through cleaning processes) and on cooled or heated
vessels.
3.2 Ventilation and pressure compensation
Thelterelementismountedintotheelectronicshousing.Ithasthe
following functions:
• Ventilation of the electronics housing
• Atmospheric pressure compensation (with relative pressure meas-
uring ranges)
→ Incaseofhorizontalmounting,turnthehousingsothatthelter
element points downward after the instrument is installed. This
provides better protection against buildup.
