This operating instructions manual applies to the following instrument
versions:
• Hardwareversion≤1.10
• Softwareversion≤3.90
3.2 Principle of operation
VEGAPULS 63 is a radar sensor in K-band technology (emitting
frequencyapprox.26GHz)forcontinuouslevelmeasurement.Itis
particularly suitable for small vessels that contain aggressive liquids
under easy process conditions.
The electronics version "Increased sensitivity" enables the use of
VEGAPULS63alsoinapplicationswithverypoorreectiveproper-
ties or products with low ervalue.
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.
Power is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbusspecicationservesascarrierofbothpoweranddigitaldata
for multiple sensors.This cable can be operated in two versions:
• via an H1 interface card in the control system and additional power
supply
• via a Linking device with HSE (High speed Ethernet) and addi-
tional power supply according to IEC 61158-2

4.1 General instructions
Select an installation position you can easily reach for mounting and
connectingaswellaslaterretrottingofadisplayandadjustment
module.The housing can be rotated by 330° without the use of any
tools.You can also install the display and adjustment module in four
dierentpositions(eachdisplacedby90°).
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cableentry.Rainandcondensationwatercanthusdraino.Thisap-
plies mainly to outdoor mounting as well as installation in areas where
high humidity is expected (e.g. through cleaning processes) or on
cooled or heated vessels.
Fig. 2: Measures against moisture ingress
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.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
The reference plane for the measuring range of the sensors is the
loweredgeoftheange.
Information:
If the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.

When mounting the VEGAPULS 63, keep a distance of at least
200 mm (7.874 in) to the vessel wall. If the sensor is installed in the
center of dished or round vessel tops, multiple echoes can arise.
These can, however, 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.

Fig. 9: Alignment in liquids
The mounting location of the radar sensor should be a place where no
otherequipmentorxturescrossthepathofthemicrowavesignals.
Vessel installations such as for example, ladders, limit switches, heat-
ing spirals, struts etc. can cause false echoes that interfere with the
usefulecho.Makesurewhenplanningyourmeasuringsitethatthe
radar signals have a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion.This ensures that the
interferingreectionsfromtheagitatorsaresavedwiththebladesin
dierentpositions.
Fig. 11: Agitators
Throughtheactionoflling,stirringandotherprocessesinthevessel,
dense foams which considerably damp the emitted signals may form
on the product surface.
If foams lead to measurement errors, you should use the biggest pos-
sible radar antennas and low frequency radar sensors (C-band).
As an alternative, sensors with guided microwave can be used. These
areunaectedbyfoamgenerationandarebestsuitedforsuchap-
plications.
Byusingastandpipe,theinuenceofvesselinstallationsandturbu-
lence can be excluded. Under these prerequisites, the measurement
of products with low dielectric constant (from 1.6) is possible.
Surge or bypass tubes must extend all the way down to the requested
min. level, as measurement is only possible within the tube.
Surge pipe
Makesureyouprovidethenecessaryupperventholeinthesurge
pipe.The hole must be aligned so that it and the polarisation marking
on the sensor are in the same plane (see illustration: "Pipe antenna
system in a tank").

tween40…80mm(1.575…3.15in).
Bypass tube
As an alternative to the surge pipe in the vessel, a tube system out-
side of the vessel is possible as a bypass tube. Select during setup
the function "Bypass tube".
Align the sensor in such a way that the polarisation marking on the

process tting must be in one plane with the tube holes or the tube connection
openings.
1 Marking of the polarisation direction
When the sensor is mounted on a bypass tube, the distance from
VEGAPULS 63 to the upper tube connection should be approx.
300 mm (11.81 in) or more. In case of extremely rough tube inner
walls, you should use an inserted tube (tube in tube) or a radar sensor
with tube antenna.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
• The electrical connection must only be carried out by trained
personnel authorised by the plant operator.
• If overvoltage surges are expected, overvoltage arresters should
be installed.
Theinstrumentrequiresaoperatingvoltageof9…32VDC.Operat-
ing voltage and the digital bus signal are carried on the same two-wire
connection cable. Power is supplied via the H1 power supply.
Connection is carried out with screened cable according to Fieldbus
specication.
Use cable with round cross section for instruments with housing and
cablegland.Toensurethesealeectofthecablegland(IPprotection
rating),ndoutwhichcableouterdiameterthecableglandissuitable
for.
Useacableglandttingthecablediameter.
Makesurethattheentireinstallationiscarriedoutaccordingtothe
Fieldbusspecication.Inparticular,makesurethatthebusistermi-
nated with suitable terminating resistors.
Caution:
No grease should be used when screwing the NPT cable gland or
steel tube into the threaded insert. Standard grease can contain
additives that corrode the connection between threaded insert and
housing.Thiswouldinuencethestabilityoftheconnectionandthe
tightness of the housing.
In systems with potential equalisation, connect the cable screen
directly to ground potential at the power supply unit, in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).
In systems without potential equalisation, connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor, the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The
low frequency potential equalisation currents are thus suppressed,
buttheprotectiveeectagainsthighfrequencyinterferencesignals
remains.

The total capacitance of the cable and of all capacitors must not
exceed 10 nF in Ex applications.
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
owoverthecablescreen.Incaseofgroundingonbothsidesthis
can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2 Connection procedure
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it to the left.
3. Loosen compression nut of the cable gland and remove blind
plug
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry
6. Lift the opening levers of the terminals with a screwdriver (see
following illustration)
7. Insert the wire ends into the open terminals according to the wir-
ing plan
Fig. 15: Connection steps 6 and 7
8. Press down the opening levers of the terminals, you will hear the
terminal spring closing
9. Check the hold of the wires in the terminals by lightly pulling on
them
10. Connect the screen to the internal ground terminal, connect the
external ground terminal to potential equalisation
