3.2Principle of operation
VEGASWING 61 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 61 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 61 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 61 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 one of these faults is detected,the electronics signals it via a defined
current to the signal conditioning instrument.The connection cable to
the sensor is also monitored for line break and short-circuit.
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,transferred as a current value to the processing system and
converted there into a switching command.
Depending on your requirements,VEGASWING 61 with two-wire
electronics can be connected to different signal conditioning instru-
ments.Compatible signal conditioning instruments are listed in chapter
"Technical data".
The data for power supply are specified in chapter "Technical data".

3.3Operation
The switching condition of VEGASWING 61 with plastic housing can
be checked when the housing is closed (signal lamp). With the basic
setting,products with a density >0.7g/cm³(0.025 lbs/in³)can be
detected.The instrument can be adapted if products with lower density
are to be measured.
On the electronics module you will find the following indicating and
adjustment elements:
lSignal lamp for indication of the switching condition (green/red)
lDIL switch for adaptation to the product density
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.
The packaging of standard instruments consists of environment-
friendly,recyclable cardboard.The sensor is also equipped with a
protective cap of ABS.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 under consideration of the notes on the
transport packaging.Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt.Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation,the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated,the packages must be stored only under
the following conditions:
lNot in the open

4Mounting
4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,process seal and process fitting,are
suitable for the existing process conditions.These include above all
the process pressure,process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data"and on the
type label.
In general,VEGASWING 61 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 refers to
water with the basic setting of the sensitivity switch ≥0.7g/cm³
(0.025 lbs/in³). When mounting VEGASWING 61,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 -water 1g/cm³(0.036 lbs/in³). For products
<0.7g/cm³(0.025 lbs/in³)and >0.5g/cm³(0.018 lbs/in³)the density
switch must be set to ≥0.5g/cm³.
Keep in mind that foams with a density >0.45 g/cm³(0.016 lbs/in³)are
detected by the sensor.This can cause faulty switchings particulary
when used as dry run protection system.

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 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.

Caution:
Do not hold VEGASWING 61 on the tuning fork.Particularly with flange
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 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.
4.2Instructions for installation
VEGASWING 61 has a defined thread starting point.This means that
every VEGASWING 61 is in the same fork position after being
screwed in.Remove therefore the supplied seal from the thread of
VEGASWING 61.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
instrument versions.

Screw VEGASWING 61 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
VEGASWING 61 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 flow.

Fig.7: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.On the screwed version you will find 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 sufficient to reach the
recommended installation position.
With flange versions,the fork is directed to the flange holes.
When used in adhesive and viscous products,the tuning fork should
protrude into the vessel to avoid buildup.For that reason,sockets for
flanges and mounting bosses should be avoided when mounting
horizontally.
IfVEGASWING 61 is mounted in the filling stream,unwanted false
measurement signals can be generated.For this reason,mount
VEGASWING 61 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
61 should be mounted in such a way that the surfaces of the blades
are parallel to the product movement.
Instruments with enamel coating should be treated very carefully and
shocks should be avoided.Unpack VEGASWING 61 directly before
installation.Insert VEGASWING 61 carefully into the vessel opening
and avoid touching any sharp vessel parts.

The gas-tight leadthrough avoids due to a second sealing the
uncontrolled penetration of the medium.The lifetime of the gastight
leadthrough depends ont he chemical resistance of the materials.See
"Technical data".
Caution:
If it is determined (e.g.by an error message of VEGASWING 61)that
medium has already penetrated into the vibrating element,the
instrument must be exchanged immediately.

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
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
Connect the operating voltage according to the following diagrams.
Take note of the general installation regulations.As a rule,connect
VEGASWING 61 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 offelectrostatic charges.InEx applications,the
installation regulations for hazardous areas must be given priority.
The data for power supply are specified 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.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
In hazardous areas,only use approved cable connections for
VEGASWING 61.
Take note of the corresponding installation regulations for Ex
applications.
Cover all housing openings conforming to standard according to
EN 60079-1.
5.2Connection procedure
With Ex instruments,the housing cover may only be opened if there is
no explosive atmosphere present.
Proceed as follows:
1Unscrew the housing cover
2Loosen compression nut of the cable entry
3Remove approx.10 cm (4in)of the cable mantle,strip approx.
1cm (0.4in)of insulation from the ends of the individual wires
