2.3 Warning about incorrect use
Inappropriate or incorrect use of this product can give rise to applica-
tion-specichazards,e.g.vesseloverllthroughincorrectmounting
or adjustment. Damage to property and persons or environmental
contamination can result. Also, the protective characteristics of the
instrument can be impaired.
2.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and directives. The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsi-
ble for the trouble-free operation of the instrument. When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
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

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

4.1 General instructions
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.
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed 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
As a standard feature, the VEGAPULS 6X 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.

deposits.Therefore,mountthedevicesothatthelterelementis
protected against deposits.
Caution:
Donotuseahigh-pressurecleaner.Thelterelementcouldbedam-

installedinthehousinginsteadofthelterelement.
The housing of VEGAPULS 6X can be rotated completely through
360°.This allows the display to be read optimally and the device to be
aligned for easy cable insertion. 2)
Depending on the version and housing material, the locking screw on
the housing neck must be loosened.The housing can then be turned
to the correct position. As soon as the this position is reached, tighten
the locking screw. Use an hexagon spanner size 3.

4.3 Mounting preparations, mounting strap
The mounting strap is supplied unassembled (optionally) as acces-
sory part of the plastic horn antenna 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.

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.

4.5 Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The polarization direction is marked by a nose on the housing, see
following drawing:
1
Fig. 14: Position of the polarisation
1 Nose for marking the direction of polarisation
Note:
Turningthehousingchangesthepolarisationandthustheeectof
false echoes on the measured value.
In order to avoid a change in the metrological properties, observe
the position of the polarisation during installation or in the case of
subsequent changes.
When mounting the device, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the device 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

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

Mount the instrument at least 200 mm (7.874 in) away from the vessel
wall.

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.
The measuring range of VEGAPULS 6X begins physically at the end
of the antenna.The min./max. adjustment, however, begins at the
referenceplane.Thereferenceplaneisdierentdependingonthe
sensor version.
• Plastic horn antenna: The reference plane is the sealing surface
on the lower edge
• Thread with integrated antenna system: The reference plane is
the sealing surface at the bottom of the hexagon
• Flange with plastic plating: The reference plane is the lower
sideoftheangeplating
• Hygienictting: The reference plane is the highest contact point
betweensensorprocessttingandweldedsocket
• Flange with lens antenna: The reference plane is the lower side
oftheange
