3.2 Principle of operation
SITRANS LVL200E 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
can be used in liquids.
Typicalapplicationsareoverllanddryrunprotection.Thesmall
tuning fork allows use in all kinds of tanks and vessels.Thanks to its
simple and rugged measuring system, SITRANS LVL200E is virtually
unaectedbythechemicalandphysicalpropertiesoftheliquid.
Itfunctionsevenunderdicultconditionssuchasturbulence,airbub-
bles, foam generation, buildup, strong external vibration or changing
products.
Function monitoring
The electronics module of SITRANS LVL200E continuously monitors
the following criteria via frequency evaluation:
• Strong corrosion or damage on the tuning fork
• Loss of vibration
• Linebreaktothepiezodrive
If one of these faults is detected or if the power supply fails, the elec-
tronicstakesonadenedoutputstatus(safestate).
Thetuningforkispiezoelectricallyenergisedandvibratesatits
mechanicalresonancefrequencyofapprox.1200Hz.Thepiezosare
xedmechanicallyandarehencenotsubjecttotemperatureshock
limitations.The frequency changes when the tuning fork is covered
by the medium.This change is detected by the integrated electronics
module and converted into a switching command.
SITRANS LVL200E is a compact instrument, i.e. it can be oper-
ated without external evaluation system.The integrated electronics
evaluates the level signal and outputs a switching signal. With this
switching signal, a connected device can be operated directly (e.g. a
warning system, a pump etc.).
Thedataforpowersupplyarespeciedinchapter"Technical data".
3.3 Operation
Withthefactorysetting,productswithadensity≥0.7g/cm³
(0.025lbs/in³)canbedetected.Theinstrumentcanbeadaptedto
products with lower density.
Ontheelectronicsmoduleyouwillndthefollowingdisplayand
adjustment elements:
• Signal lamp for indication of the switching condition (green/red)
• DIL switch for sensitivity adjustment
• Mode adjustment for selection of the switching condition (A/B)

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.
In general, SITRANS LVL200E can be installed in any position.The
instrument only has to be mounted in such a way that the tuning fork
is at the height of the desired switching point.
The tuning fork has lateral markings (notches) that indicate the
switching point with vertical mounting. The switching point applies
to water in conjunction with the basic setting of the density switch
≥0.7g/cm³(0.025lbs/in³).WhenmountingSITRANSLVL200E,make
sure that this marking is at the height of the requested switching point.
Keep in mind that the switching point of the instrument will shift if the
mediumhasadensityotherthanwater-wateris1g/cm³(0.036lbs/
in³).Forproducts≤0.7g/cm³(0.025lbs/in³)and≥0.5g/cm³
(0.018lbs/in³)thedensityswitchmustbesetto≥0.5g/cm³.
Keepinmindthatfoamswithadensity≥0.45g/cm³(0.016lbs/in³)
are detected by the sensor. This can lead to erroneous switchings,
particulary when the sensor is used for dry run protection.

Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your SITRANS LVL200E 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appliesmainlytooutdoormountingaswellasinstallationin
areas where high humidity is expected (e.g. through cleaning pro-
cesses) or on cooled or heated vessels.

Caution:
Do not hold SITRANS LVL200E on the tuning fork. Particularly with
angeortubeversions,thetuningforkcanbedamagedjustbythe
weight of the instrument.Transport coated instruments very carefully
and avoid touching the tuning fork.
Remove the packaging or the protective cover just before installation.
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.
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
SITRANSLVL200Ehasadenedthreadstartingpoint.Thismeans
that every SITRANS LVL200E is in the same fork position after being
screwed in. Remove therefore the supplied seal from the thread of
SITRANS LVL200E. This seal is not required when using a welded
socket with O-ring in front.
Keep in mind that this welded socket is not suitable for coated instru-
ment versions.
Screw SITRANS LVL200E completely into the welded socket.The
later position can be determined already before welding. Mark the
appropriate position of the welded socket. Before welding, unscrew
SITRANS LVL200E and remove the rubber ring from the welded
socket.The welded socket has a marking (notch). Weld the socket
with the notch facing upward, or in case of pipelines (DN 32 up to
DN50),alignedwiththedirectionofow.

1 Marking
Incaseofhorizontalmountinginadhesiveandviscousproducts,
the surfaces of the tuning fork should be vertical in order to reduce
builduponthetuningfork.Onthescrewedversionyouwillnda
marking on the hexagon. With this you can check the position of the
tuning fork when screwing it in. When the hexagon touches the seal,
thethreadcanstillbeturnedbyapprox.halfaturn.Thisissucientto
reach the recommended installation position.
Inthecaseofangeversions,theforkisalignedwiththeangeholes.
When used in adhesive and viscous products, the tuning fork should
protrude into the vessel to avoid buildup. For that reason, sockets
forangesandmountingbossesshouldbeavoidedwhenmounting
horizontally.
Iftheinstrumentismountedinthellingstream,unwantedfalse
measurement signals can be generated. For this reason, mount the
instrument 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.
Fig.8:Inowingmedium
To make sure the tuning fork of SITRANS LVL200E generates as little
resistanceaspossibletoproductow,mountthesensorsothatthe
surfaces are parallel to the product movement.

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 SITRANS LVL200E, 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.
agitators or turbulence in the vessel, can cause the extension tube of
SITRANS LVL200E to vibrate in resonance.This leads to increased
stress on the upper weld joint. Should a longer tube version be neces-
sary, you can provide a suitable support directly above the tuning fork
to secure the extension tube.
This measure applies mainly to applications in Ex areas category 1G
or WHG. Make sure that the tube is not subject to bending stress due
to this measure.
Fig. 9: Lateral suppot of SITRANS LVL200E
Instruments with enamel coating should be treated very carefully and
shocks should be avoided. Unpack SITRANS LVL200E directly before
installation. Insert SITRANS LVL200E carefully into the vessel open-
ing and avoid touching any sharp vessel parts.
The second seal of the gas-tight leadthrough (option) prevents an
uncontrolled leakage of the medium.The service life of the gas-tight
leadthrough depends on the chemical resistance of the materials.
See "Technical data".
Caution:
If it is determined (e.g. via an error message from SITRANS LVL200E)
that medium has already penetrated into the vibrating element, the
instrument must be exchanged immediately.

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.
• Alwaysswitchopowersupply,beforeconnectingordisconnect-
ing the instrument.
Inhazardousareasyoumusttakenoteoftherespectiveregulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
Connect the voltage supply according to the following diagrams.Take
note of the general installation regulations. As a rule, connect SI-
TRANS LVL200E to vessel ground (PA), or in case of plastic vessels,
to the next ground potential. On the side of the instrument housing
there is a ground terminal between the cable entries.This connection
servestodrainoelectrostaticcharges.InExapplications,theinstal-
lationregulationsforhazardousareasmustbegivenpriority.
Thedataforpowersupplyarespeciedinchapter"Technical data".
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should
be used.
Use cable with round cross-section. A cable outer diameter of
5…9mm(0.2…0.35in)ensuresthesealeectofthecablegland.
Ifyouareusingcablewithadierentdiameterorcross-section,
exchange the seal or use a suitable cable gland.
Inhazardousareas,useonlyapprovedcableconnectionsforSI-
TRANS LVL200E.
Take note of the corresponding installation regulations for Ex applica-
tions.
Cover all housing openings conforming to standard according to
EN 60079-1.
5.2 Connection procedure
With Ex instruments, the housing cover may only be opened if there is
no explosive atmosphere present.
Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable entry gland
