The scope of delivery encompasses:
• LEVEL SWITCH 8110 point level switch
• Test magnet
• Documentation
– This operating instructions manual
– Ifnecessary,certicates
The LEVEL SWITCH 8110 consists of the components:
• Housing with electronics

• Technical data
3.2 Principle of operation
LEVEL SWITCH 8110 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.Withatuning
fork of only 38 mm length, LEVEL SWITCH 8110 can be also mount-
ed e.g. in pipelines from DN 25. The small tuning fork allows use in
vessels, tanks and pipes.Thanks to its simple and robust measuring

system,LEVELSWITCH8110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 LEVEL SWITCH 8110 continuously moni-
tors the following criteria via frequency evaluation:
• Strong corrosion or damage on the tuning fork
• Loss of vibration
• Linebreaktothepiezodrive
If a malfunction is detected or in case of voltage supply, the electron-
icstakesonadenedswitchingstatus,i.e.theoutputisopen(safe
state).
Thetuningforkispiezoelectricallyenergisedandvibratesatitsme-
chanicalresonancefrequencyofapprox.1100Hz.Whenthetuning
fork is submerged in the product, the frequency changes.This change
is detected by the integrated electronics module and converted into a
switching command.
LEVEL SWITCH 8110 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 Adjustment
The switching status of LEVEL SWITCH 8110 can be checked when
the housing is closed (signal lamp). Products with a density > 0.7 g/
cm³ (0.025 lbs/in³) or ordered optionally with a density > 0.5 g/cm³
(0.018 lbs/in³) can be detected.
3.4 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.

4.1 General instructions
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
Theinstrumentissuitableforstandardandextendedambientcondi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
In general, LEVEL SWITCH 8110 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.
Keep in mind that the swichting point can vary dependent on the
installation position.
The switching point refers to the medium water (1 g/cm³/0.036 lbs/
in³). Please keep in mind that the switching point of the instrument
shiftswhenthemediumhasadensitydieringfromwater.

Do not hold LEVEL SWITCH 8110 on the tuning fork.
Theprocessttingmustbesealedifthereisgaugeorlowpressure
in the vessel. Before use, check if the sealing 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.
4.2 Mounting instructions
For threaded versions of LEVEL SWITCH 8110 in combination with a
mounting boss with O-ring in front and welding marking.
LEVELSWITCH8110withthreadsizes¾"and1"haveadened
thread.This means that every LEVEL SWITCH 8110 is in the same
positionafterbeingscrewedin.Removethereforethesuppliedat
sealfromthethreadofLEVELSWITCH8110.Thisatsealisnot
requiredwhenusingaweldedsocketwithfront-ushseal.
Before welding, unscrew LEVEL SWITCH 8110 and remove the rub-
ber ring from the welded socket.
Theweldedsocketisprovidedwithamarking(notch).Forhorizontal
mounting, weld the socket with the notch facing upward or downward;
inpipelines(DN25toDN50)alignedwiththedirectionofow.

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.The position of the tuning fork is indicated
byamarkingonthehexagonofLEVELSWITCH8110.Withthis,
you can check the position of the tuning fork when screwing it in.

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,
qualiedpersonnelauthorisedbytheplantoperator.
• Alwaysswitchopowersupply,beforeconnectingordisconnect-
ing the instrument.
The instrument is connected with standard three-wire cable without
shielding.Ifelectromagneticinterferenceisexpectedwhichisabove
the test values of EN 61326 for industrial areas, shielded cable should
be used.
Make sure that the cable used has the required temperature resist-

6.1 Indication of the switching status
The switching status of the electronics can be checked via the signal
lamps (LEDs) integrated in the upper part of the housing.
The signal lamps have the following meaning:
• Green lights - voltage supply connected
• Yellow lights - vibrating element covered
• Redlightsbriey-functiontestduringinstrumentstart(for0.5s)
• Red lights - shortcircuit or overload in the load circuit (sensor
output high-impedance)
• Redashes-Erroronthevibratingelementortheelectronics
(sensor output high impedance)
6.2 Simulation
The LEVEL SWITCH 8110 has an integrated function for simula-
tion of the output signal which can be activated magnetically. Please
proceed as follows:
→ Hold the test magnet (accessory) against the circle symbol with
the label "TEST" on the instrument housing
Fig. 9: Simulation of the output signal
The test magnet changes the current switching condition of the instru-
ment.You can check the change on the signal lamp. Please note that
all connected device are activated during the simulation.
If LEVEL SWITCH 8110 does not switch over after several tests with
the test magnet, you have to check the plug connection and the
connection cable and try it again. If there is no switching function, the
electronicswillbedefective.Inthiscaseyouhavetoexchangethe
electronics or return the instrument to our repair department.
Caution:
It is absolutely necessary that you remove the test magnet from the
instrument housing after the simulation.
