3.2 Principle of operation
VEGAWAVE 63 is a point level sensor with tuning fork for point level
detection.
It is designed for industrial use in all areas of process technology and
is preferably used for bulk solids.
Typicalapplicationsareoverllanddryrunprotection.Thankstoits
simple and robust measuring system, VEGAWAVE 63 is virtually unaf-
fected by the chemical and physical properties of the bulk solid.
It also works when subjected to strong external vibrations or changing
products.
Solid detection in water
If VEGAWAVE 63 was ordered for solids detection in water, the tuning
fork is set to the density of water. In air or when immersed in water
(density: 1 g/cm³/0.036 lbs/in), VEGAWAVE 63 signals "uncovered".
Only when the vibrating element is also covered with solids (e.g.
sand, sludge, gravel etc.) will the sensor signal "covered".
Function monitoring
The electronics module of VEGAWAVE 63 continuously monitors the
following criteria:
• Correct vibrating frequency
• Linebreaktothepiezodrive
If one of these faults is detected, the electronics signals this via a
denedcurrenttothesignalconditioninginstrument.Theconnection
cable to the vibrating element is also monitored.
Thetuningforkispiezoelectricallyenergisedandvibratesatits
mechanicalresonancefrequencyofapprox.150Hz.Whenthetuning
fork is submerged in the product, the vibration amplitude changes.
This change is detected by the integrated electronics module and
converted into a switching command.
VEGAWAVE 63 with NAMUR electronics can be connected to dif-
ferentNAMURampliersdependingonyourrequirements.Thespeci-
cationsforNAMURampliersareavailableinthe"Technical data".
Thedataforpowersupplyarespeciedinchapter"Technical data".

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
processtting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.
Youcanndthespecicationsinchapter"Technical data" and on the
nameplate.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
In general, VEGAWAVE 63 can be installed in any position.The instru-
ment only has to be mounted in such a way that the vibrating element
is at the height of the desired switching point.
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gland.Rainandcondensationwatercanthusdraino.This
applies 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.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Makesurethatthedegreeofcontaminationspeciedinchapter
"Technical data" meets the existing ambient conditions.
Fig. 2: Measures against moisture ingress
Do not hold VEGAWAVE 63 on the vibrating element. Especially with
angeandtubeversions,thesensorcanbedamagedbytheweight
of the instrument.
Remove the protective cover just before mounting.

Theprocessttingmustbesealedifthereisgaugeorlowpressurein
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
Themax.permissiblepressureisspeciedinchapter"Technical
data" or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.
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.
4.2 Mounting instructions
Duetotheeectsofagitators,equipmentvibrationorsimilar,thelevel
switch can be subjected to strong lateral forces. For this reason, do
not use an overly long extension tube for VEGAWAVE 63, but check
if you can mount a short level switch on the side of the vessel in
horizontalposition.
Extreme vibration caused by the process or the equipment, e.g. agita-
torsorturbulenceinthevessel,e.g.byuidisation,cancausethe
extension tube of VEGAWAVE 63 to vibrate in resonance.This leads
to increased stress on the upper weld joint. Should a longer tube ver-
sion be necessary, you can provide a suitable support directly above
the vibrating element to secure the extension tube.
This measure applies mainly to applications in Ex areas. Make sure
that the tube is not subject to bending stress due to this measure.
IfVEGAWAVE63ismountedinthellingstream,unwantedfalse
measurement signals can be generated. For this reason, mount
VEGAWAVE 63 at a position in the vessel where no disturbances, e.g.
fromllingopenings,agitators,etc.,canoccur.
This applies particularly to instrument types with long extension tube.

The vibrating element should protrude into the vessel to avoid
buildup.Forthatreason,avoidusingmountingbossesforanges
andscrewedttings.Thisappliesparticularlytousewithadhesive
products.
In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor
in the vessel.We recommend selecting an installation location where
the vibrating fork detects an average value of the material cone.
The tuning fork must be mounted in a way that takes the arrangement
ofthellingandemptyingaperturesintoaccount.
To compensate measurement errors caused by the material cone in
cylindrical vessels, the sensor must be mounted at a distance of d/6
from the vessel wall.

With the potentiometer you can adapt the switching point to the solid.

By default, the potentiometer of VEGAWAVE 63 is set to the right stop
(> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids,
turn the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/
in³).VEGAWAVE 63 will thus be more sensitive and can detect light-
weight solids more reliably.
For instruments detecting solids in water, these settings are not ap-
plicable.The density range is preset and must not be changed.

6 Setup
VEGAWAVE 63 • NAMUR
32259-EN-181126
The characteristics reversal can be carried out with the DIL switch.
You can choose between falling characteristic curve (switch position
max.) and rising characteristic curve (switch position min.).This al-
lows you to output the desired current.
Modes
• min. - rising characteristic curve (High current when immersed)
• max. - falling characteristics (Low current when immersed)
The NAMUR output can be switched over to falling or rising charac-
teristics (see also "Function table").
The simulation key is located in a recess on the upper side of the
electronics module. Push the simulation key with a suitable object
(screwdriver, pen, etc.).
When the key is pushed, a line break between sensor and process-
ing unit is simulated. The signal lamp on the sensor extinguishes.The
measuring system must signal a fault and take on a safe state when
the key is pushed.
Keep in mind that downstream connected instruments will be acti-
vated during operation. This allows you to check the correct function
of the measuring system.
