3 Product description
VEGAPULS 62 • HART and accumulator pack
40793-EN-170405
The actual values that can be reached depend on the measurement
conditions, the antenna system or the standpipe or bypass.
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereectedbytheproduct
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level.The determined level is converted into an appropri-
ate output signal and outputted as measured value.
The instrument is powered via an integrated accumulator. This allows
operation of the instrument independently of the mains or a control
system. To achieve a longer battery lifetime, the instrument is preset
to HART multidrop.This puts a load of only 4 mA current on the ac-
cumulator.
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 %

humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Make sure before mounting 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 in particular are:
• 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.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.The dust protection caps do
notprovidesucientprotectionagainstmoisture.

4.2 Mounting preparations
The instrument is also available in versions with an antenna whose
diameterislargerthantheprocesstting(thread,ange).Insuch
casestheantennamustbedisconnectedfromtheprocesstting
before mounting.
Proceed as follows:
1. Loosen the hexagon socket screws (3) on the antenna socket
withanAllenwrench(size3)
2. Remove the antenna (4)
Note:
The plastic cone may not be pulled out of the antenna socket.
3. Insert the antenna from below into the vessel socket and secure it
againstfallingo
4. Retighten the antenna with hexagon screws to the antenna
socket; max. torque see chapter "Technical data"
Note:
The radar sensor with rinsing air connection or with antenna exten-
sionhasanotchontheantennasocketforpolarization.Thisnotch
mustbealignedwiththemarkingontheprocesstting.

4.3 Mounting instructions
The illustrations with the following mounting instructions show a radar
sensor with horn antenna.The mounting instructions apply analo-
gously also to the version with parabolic antenna.
The emitted radar impulses of the radar sensor are electromagnetic
waves.The polarisation is the direction of the electrical wave compo-
nent.Byturningtheinstrumentintheconnectionangeormounting
boss,thepolarisationcanbeusedtoreducetheeectsoffalse
echoes.
Thepositionofthepolarisationismarkedontheprocessttingofthe
instrument.

2 Markingwithangeversion
When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the sensor is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can be suppressed by an appropriate adjustment (see chapter
"Setup").
If you cannot maintain this distance, you should carry out a false
signal suppression during setup.This applies particularly if buildup on
the vessel wall is expected. In such cases, we recommend repeating
the false signal suppression at a later date with existing buildup.

In vessels with conical bottom it can be advantageous to mount the
sensor in the centre of the vessel, as measurement is then possible
down to the bottom.

Tip:
The instrument is also optionally available with an antenna extension.
The antenna length can be selected (either ex works or later) to allow
the antenna to protrude slightly out of the end of the mounting socket.
Duetotheantennaextensionhowever,disturbingreectionsare
generated in the close-up range.This can lead to an increase in the
requiredminimumdistance,especiallywithpoorlyreectingmedia
such as plastic powder. In practice, a cleanly constructed mounting
socket, if necessary with rounded edges, introduces fewer disturbing
inuencesthananantennaextension.
In liquids, direct the sensor as perpendicular as possible to the prod-
uct surface to achieve optimum measurement results.
