3.2Principle of operation
VEGASON 62 is an ultrasonic sensor for continuous level
measurement.It is suitable for liquids and solids in virtually all
industries,particularly in the water and waste water industry.
The transducer of the ultrasonic sensor transmits short
ultrasonic pulses to the measured product.These pulses are
reflected by product surface and received again by the
transducer as echoes.The running time of the ultrasonic
pulses from emission to reception is proportional to the
distance and hence the level.The determined level is
converted into an appropriate output signal and outputted as
measured value.
Power supply via the Profibus DP/PA segment coupler or
VEGALOG 571 EP cards.Atwo-wire cable according to
Profibus specification serves as carrier of both power and
digital data signals for multiple sensors.The instrument profile
of VEGASON 62 corresponds to profile specification version
3.0.
The GSD (instrument master files)and bitmap files necessary
for planning your Profibus-DP-(PA)communication network
are available from the download section on the VEGA
homepage www.vega.com under "Services -Downloads -
Software -Profibus".There you can also find the appropriate
certificates.In a PDM environment,an EDD (Electronic Device
Description)is also required to enable the full range of sensor
functions (also available as a download).A CD with the
appropriate files can be ordered via e-mail under info@de.
vega.com or by phone from one of the VEGA agencies under
the order number "DRIVER.S".
The backlight of the indicating and adjustment module is
powered by the sensor.Prerequisite is a certain level of supply
voltage.
The data for voltage supply are specified in chapter "Technical
data".
The optional heating requires its own power supply.You can
find further details in the supplementary instructions manual
"Heating for indicating and adjustment module".
This function is generally not available for approved instru-
ments.

3.3Operation
VEGASON 62 can be adjusted with different adjustment
media:
lwith indicating and adjustment module
lWith the suitable VEGA DTM in conjunction with an
adjustment software according to the FDT/DTM standard,
e.g.PACTware™and PC
lthe Simatic adjustment program PDM
The entered parameters are generally saved in VEGASON 62,
optionally also in the indicating and adjustment module or in
PACTware™.
3.4Packaging,transport and storage
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 environ-
ment-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 under consideration of the notes
on the transport packaging.Nonobservance of these instruc-
tions 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
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration

4Mounting
4.1General instructions
Make sure that the wetted parts of the instrument,especially
the seal and process fitting,are suitable for the existing
process conditions such as pressure,temperature etc.as well
as the chemical properties of the medium.
You can find the specifications in chapter "Technical data".
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module.The housing can be rotated
by 330°without the use of any tools.You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
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 down-
ward 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.
Fig.2:Measures against moisture penetration
The reference plane for the measuring range is the lower edge
of the transducer.
Make sure that a min.distance -the so called dead zone -
below the reference plane is maintained in which a measure-
ment is not possible.The exact value of the dead zone is
stated in chapter "Technical data".

Gauge pressure in the vessel does not influence VEGASON
62.Low pressure or vacuum does,however,damp the
ultrasonic pulses.This influences the measuring result,
particularly if the level is very low.With pressures under -
0.2bar (-20 kPa)you should use a different measuring
principle,e.g.radar or guided microwave.

4.2Mounting instructions
Screw VEGASON 62 into the mounting socket with an
appropriate spanner applied to the hexagon of the process
fitting.Max.torque see chapter "Technical data".
Warning:
The housing must not be used to screw the instrument in!
Applying tightening force can damage internal parts of the
housing.
When mounting the sensor,keep a distance of at least 200 mm
(7.874 in)to the vessel wall.If the sensor is installed in the
center of dished or round vessel tops,multiple echoes can
arise.These can,however,be suppressed by an appropriate
adjustment (see "Setup").

> 200 mm
Fig.5:Mounting on round vessel tops

2Vessel center or symmetry axis
If you cannot keep this distance you should carry out a false
echo storage before setup.This applies mainly if buildup on
the vessel wall is expected.In this case,we recommend
repeating a false echo storage later with existing buildup.
In vessels with conical bottom it can be advantageous to
mount the sensor in the center of the vessel,as measurement
is then possible down to the lowest point of the vessel bottom.

If the reflective properties of the medium are good,you can

length.You will find recommended values for socket heights in
the following illustration.The socket end should be smooth and
burr-free,if possible also rounded.Carry out a false echo
storage.

To reduce the min.distance to the medium,you can also
mount VEGASON 62 with a beam deflector.By doing this,it is
possible to fill the vessel nearly to maximum.Such an
arrangement is suitable primarily for open vessels such as e.g.
overflow basins.

Mounting

The ultrasonic sensor should be installed at a location where
no installations cross the ultrasonic beam.
Vessel installations such as for example,ladders,limit
switches,heating spirals,struts etc.can cause false echoes
superimposed on the useful echo.Make sure when planning
your measuring site that the ultrasonic signals have "free
access"to the measured product.
In case of existing vessel installations,a false echo storage
should be carried out during setup.
If large vessel installations such as struts or supports cause
false echoes,these can be attenuated through supplementary
measures.Small,inclined sheet metal or plastic baffles above
the installations scatter the ultrasonic signals and avoid direct
false echoes.

If there are agitators in the vessel,a false echo storage should
be carried out with the agitators in motion.This ensures that
the interfering reflections from the agitators are saved with the
blades in different positions.

Do not mount the instruments in or above the filling stream.
Make sure that you detect the product surface,not the
inflowing product.
Fig.13:Inflowing liquid
Through the action of filling,stirring and other processes in the
vessel,dense foams which considerably damp the emitted
signals may form on the product surface.
If foams are causing measurement errors,the sensor should
be used in a standpipe or,alternatively,the more suitable
guided radar sensors (TDR)should be used.
Guided radar is unaffected by foam generation and is
particularly suitable for such applications.

If there are strong air currents in the vessel,e.g.due to strong
winds in outdoor installations or air turbulence,e.g.by cyclone
extraction you should mount VEGASON 62 in a standpipe or
use a different measuring principle,e.g.radar or guided radar
(TDR).
By using a standpipe (surge or bypass tube), the influence of
vessel installations,foam generation and turbulence is
excluded.
Standpipes must extend all the way down to the requested
min.level,as measurement is only possible within the tube.
