components through incorrect mounting or adjustment. Also the pro-
tectivecharacteristicsoftheinstrumentcanbeinuenced.
2.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and guidelines. The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsible
for the trouble-free operation 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.
The safety instructions in this operating instructions manual, the na-
tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may be
carried out only by personnel authorised by the manufacturer. Arbi-
traryconversionsormodicationsareexplicitlyforbidden.
The safety approval markings and safety tips on the device must also
be observed.
Depending on the instrument version, the emitting frequencies are in
the C, K or W band range. The low emitting frequencies are far below
the internationally approved limit values.When used correctly, the

2.7 Radio license for Europe
The instrument was tested according to the latest issues of the har-
monizedstandards:
• EN 302372 - Tank Level Probing Radar
• EN 302729 - Level Probing Radar
It is hence approved for use inside and outside closed vessels in
countries of the EU.
In EFTA countries, the use is approved as far as these standards
were implemented.
For operation inside of closed vessels, the following conditions must
befullled:
• The instrument must be permanently mounted on a closed vessel
made of metal, reinforced concrete, or comparable attenuating
materials
• Flanges,processttingsandmountingaccessoriesmustensure
the microwave impermeability of the vessel and not let the radar
signal escape to the outside
• If necessary, existing viewing windows in the vessel must be
coated with a microwave impermeable material (e.g. electrically
conductive coating)
• Manholesandangesonthevesselmustbeclosedandsealedto
avoid penetration of the radar signal
• The instrument should be preferably mounted on top of the vessel
with antenna orientation downward
• The instrument must only be installed and maintained by appropri-
atelyqualiedsta

3.2 Principle of operation
VEGAPULS 64 is a radar sensor for continuous level measurement of
liquids.
Thesmallprocessttingsoerparticularadvantagesinsmalltanksor
tight mounting spaces.The very good signal focusing ensures the use
in vessels with many installations such as stirrers and heating spirals.

The instrument emits a continuous radar signal through its antenna.
This signal is frequency modulated in the form of a sawtooth wave.
Theemittedsignalisreectedbythemediumandreceivedbythe
antenna as an echo.

VEGAPULS 64 • 4 … 20 mA/HART - two-wire
51141-EN-160815
The frequency of the received signal always deviates from the actual
emittingfrequency.Thefrequencydierenceisproportionaltothe
distanceandthustothellingheight.Thisdierenceiscalculated
viaspecialalgorithmsinthesensorelectronics.Thedeterminedll-
ing height is then converted into a corresponding output signal and
outputted as the measured value.
3.3 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 %
3.4 Accessories and replacement parts
The display and adjustment module PLICSCOM is used for measured
value indication, adjustment and diagnosis. It can be inserted into the
sensor and removed at any time.
Youcanndfurtherinformationintheoperatinginstructions"Display
and adjustment module PLICSCOM" (Document-ID 27835).
The interface adapter VEGACONNECT enables the connection of
communication-capable instruments to the USB interface of a PC. For
parameter adjustment of these instruments, the adjustment software
PACTware with VEGA-DTM is required.

4.1 General instructions
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• Loop the connection cable downward in front of the cable gland
This applies particularly to:
• Outdoor mounting
• Installations in areas where high humidity is expected (e.g. through
cleaning processes)
• Installations on cooled or heated vessels
Make sure that all parts of the instrument exposed to the process are
suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions are particularly:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences
Youcannddetailedinformationontheprocessconditionsinchapter
"Technical data" as well as on the type label.
As a standard feature, the VEGAPULS 64 is separate from the pro-
cess through its plastic antenna encapsulation.
Optionally, the instrument is available with a Second Line of Defense
(SLOD), a second process separation. It is located as gas-tight
leadthrough between the process component and the electronics.
This means additional safety against penetration of the medium fron
the process into the instrument.
4.2 Mounting versions, plastic horn antenna
The optional mounting strap allows simple mounting of the instrument
on a wall, ceiling or boom. Especially in the case of open vessels, this
isasimpleandeectivewaytoalignthesensortothesurfaceofthe
bulk solid material.
The following versions are available:
• Length 300 mm
• Length 170 mm

The instrument is normally mounted vertically with a bracket on the
ceiling.
This allows swivelling the sensor up to 180° for optimal orientation
and rotating for optimal connection.

Thecombicompressionangeissuitablefordierentvesselanges
DN 80, ASME 3" and JIS 80. It comes not sealed against the radar
sensorandcanthusonlybeusedunpressurized.Itcanberetrotted
oninstrumentswithsinglechamberhousing,retrottingtoadouble

4.3 Mounting preparations, mounting strap
The mounting strap is supplied unassembled (optionally) and must be
screwed to the sensor before setup with three hexagon socket screws
M5 x 10 and spring washers. Max. torque, see chapter "Technical
data".Requiredtools:Allenwrenchsize4.
Therearetwodierentvariantsofscrewingthestraptothesensor,
see following illustration:

2 For angle of inclination, innitely variable
Depending on the selected variant, the sensor can be rotated in the
strap:
• Single chamber housing
– Angle of inclination in three steps 0°, 90° and 180°
– Angleofinclination180°,innitelyvariable
• Double chamber housing
– Angle of inclination in two steps 0° and 90°
– Angleofinclination90°,innitelyvariable

Afteracertaintime,PTFEplatedangeshaveanormalvoltageloss.
Forcompensation,discspringsmustbeusedfortheangescrews.
We recommended elastic washers or detent edged rings:
