3.2Principle of operation
VEGASWING 51 is a point level sensor with tuning fork for level
detection.
It is designed for industrial use in all areas of process technology and
can be used in liquids.
Typical applications are overfill and dry run protection.With a tuning
fork of only 40 mm length,VEGASWING 51 can be also mounted,e.g.
in pipelines from DN 32.The small tuning fork allows use in vessels,
tanks and pipes.Thanks to its simple and robust measuring system,
VEGASWING 51 is virtually unaffected by the chemical and physical
properties of the liquid.
It functions even under difficult conditions such as turbulence,air
bubbles,foam generation,buildup,strong external vibration or
changing products.
Fault monitoring
The electronics module of VEGASWING 51 continuously monitors via
frequency evaluation the following criteria:
lStrong corrosion or damage on the tuning fork
lloss of vibration
lLine break to the piezo drive
If a malfunction is detected or in case of power failure,the electronics
takes on a defined switching condition,i.e.the contactless electronic
switch opens (safe condition).
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx.1200 Hz.The piezos are
fixed 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.
VEGASWING 51 is a compact instrument,i.e.it can be operated
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,aPLC,a pump etc.).
The data for power supply are specified in chapter "Technical data".
3.3Operation
The switching status of VEGASWING 51 can be checked with closed
housing (signal lamp). Products with a density >0.7g/cm³(0.025 lbs/
in³)can be detected.

4.1General instructions
Make sure that all parts of the instrument in contact with the measured
product,especially the sensor element,process seal and process
fitting,are suitable for the existing process conditions such as process
pressure,process temperature as well as the chemical properties of
the medium.
You can find the specifications in chapter "Technical data"in the or on
the type label.
In general,VEGASWING 51 can be installed in any position.The
instrument simply has be mounted in such a way that the tuning fork is
at the height of the desired switching point.
The tuning fork has lateral marking (notches), marking the switching
point with vertical mounting.The switching point refers to water (1g/
cm³/0.036 lbs/in³). When mounting VEGASWING 51,make sure that
this marking is at the height of the requested switching point.Keep in
mind that the switching point of the instrument is shifted if the medium
has a density other than water.

Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your VEGASWING 51 additional protection against
moisture penetration by leading the connection cable downward in
front of the cable entry.Rain and condensation water can thus drain
off.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.

The process fitting 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 specified 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.
4.2Mounting instructions
For welded socket with O-ring in front and welding marking.
VEGASWING 51 has a defined thread outlet.This means that every
VEGASWING 51 is in the same position after being screwed in.
Remove therefore the supplied flat seal from the thread of
VEGASWING 51.This flat seal is not required when using a welded
socket with front-flush seal.
Before welding,unscrew VEGASWING 51 and remove the rubber ring
from the welded socket.
The welded socket has a marking (notch). For horizontal mounting,
weld the socket with the notch facing upward or downward;in
pipelines (DN 32 to DN 50)aligned with the direction of flow.

Fig.5:Marking on the welded socket
1Marking
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 VEGASWING 51.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 sufficient to reach the recommended installation position.
In adhesive and viscous products,the surfaces of the tuning fork
should protrude into the vessel to avoid buildup.Therefore sockets for
flanges and mountings bosses should not exceed a certain length.

Fig.6:Adhesive products
IfVEGASWING 51 is mounted in the filling stream,unwanted false
measurement signals can be generated.For this reason,mount
VEGASWING 51 at a position in the vessel where no disturbances,e.
g.from filling openings,agitators,etc., can occur.
To minimise flow resistance caused by the tuning fork,VEGASWING
51 should be mounted in such a way that the surfaces of the blades
are parallel to the product movement.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
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.Depending on the plug
connection,you have to select the outer diameter of the cable
respectively so that the seal effect of the cable gland is ensured.
lValve plug DIN 43650,ø4.5…7mm
lValve plug DIN 43650 with IDC method of termination,ø5.5…8mm
Use cable with a round wire cross section and tighten the cable gland.
When mounting outdoors,on cooled vessels or in humid areas,in
which cleaning is carried out e.g.with steam or high pressure,it is
particularly important to seal the cable gland.

We recommend connecting VEGASWING 51 in such a way that the
switching circuit is open when there is a level signal,line break or
failure (safe condition).
Warning:
The instrument must not be operated without an intermediately
connected load,because the electronics would be destroyed if
connected directly to the mains.It is not suitable for connection to low
voltage PLC inputs.
For direct control of relays,contactors,magnet valves,warning lights,
horns etc.
Domestic current is temporarily lowered below 1mAafter switching off
the load so that contactors,whose holding current is lower than the
constant domestic current of the electronics (3mA), are reliably
switched off.

6.1Indication of the switching status
The switching status of the electronics can be checked via the signal
lamp integrated in the upper part of the housing.
6.2Function test
VEGASWING 51 has an integrated test switch which can be activated
magnetically.Proceed as follows to test the instrument:
àHold the test magnet (accessory)to the magnet symbol on the
instrument housing
Fig.11:Function test
The test magnet changes the current switching condition of the
instrument.You can check the change on the signal lamp.Please note
that the connected instruments are activated during the test.
IfVEGASWING 51 does not switch over after several tests with the
test magnet,you have to check the plug connection and the
connection cable and test the instrument 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.
