VEGASWING 51 consists of the following components:
lHousing with electronics
lprocess fitting with tuning fork
Fig.1:VEGASWING 51
3.2Principle of operation
VEGASWING 51 is a 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 25.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 oscillator 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 stated in chapter "Technical
data"in the "Supplement".
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.
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.

4Mounting
4.1General instructions
In general,VEGASWING 51 can be mounted in any position.
The instrument must be mounted in such a way that the tuning
fork is at the height of the requested 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 mounting
outdoors,in areas where moisture is expected (e.g.by
cleaning processes)or on cooled or heated vessels.

Mounting

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 stated in chapter "Technical
data"in the "Supplement"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 on the housing can damage its
rotational mechanical parts.
To screw in,use the hexagon above the thread.
4.2Mounting instructions
For welded socket with O-ring in front and welding marking.
VEGASWING 51 has a defined thread runout point.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 O-ring.
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 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.

IfVEGASWING 51 is mounted in the filling stream,unwanted
false measurements may be generated.Mount VEGASWING
51 at a location in the vessel where no disturbing influence
from e.g.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 voltage supply
5.1Preparing the connection
Generally note the following safety instructions:
lConnect only in the complete absence of line voltage
VEGASWING 51 is connected with standard 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.

The instrument is used for direct control of relays,contactors,
magnet valves,warning lights,horns etc.It must not be
operated without intermediately connected load,because the
electronic would be destroyed if connected directly to mains.It
is not suitable for connection to low voltage PLC inputs.
Domestic current is temporarily lowered below 1mAafter
switching offthe load so that contactors,whose holding current
is lower than the constant domestic current of the electronics
(3mA), are reliably switched off.
