3.2Principle of operation
VEGASON 61 is an ultrasonic sensor for continuous level measure-
ment.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.
Four-wire electronics with separate power supply.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
Measured value transmission is carried out via the 4…20 mA/HART
output separate from power supply.
The background lighting of the indicating and adjustment module is
powered by the sensor.Prerequiste is a certain heigt of the operating
voltage.You can find the exact voltage specifications in chapter
"Technical data".
3.3Operation
VEGASON 61 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
lwith manufacturer-specific adjustment programs AMS™or PDM
lWith a HART handheld
The entered parameters are generally saved in VEGASON 61,
optionally also in the indicating and adjustment module or in
PACTware.

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.
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 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.
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 measurement 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 61.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 61 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 chapter
"Setup").

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.

To reduce the min.distance to the medium,you can also mount
VEGASON 61 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.

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 that interfere with
the useful echo.Make sure when planning your measuring site that the
ultrasonic signals have a "clear view"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 61 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.

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
lIf overvoltage surges are expected,overvoltage arresters should
be installed
Tip:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the sensors
and power supply units.
Supply voltage and current output are carried on separate two-wire
connection cables if reliable separation is required.The supply voltage
range can differ depending on the instrument version.
The data for power supply are specified in chapter "Technical data".
The standard version can be operated with an earth-connected current
output,the Exd version must be operated with a floating output.
This instrument is designed in protection class I.To maintain this
protection class,it is absolutely necessary that the ground conductor
be connected to the internal ground terminal.Take note of the general
installation regulations.
As a rule,connect the instrument to vessel ground (potential
euqalisation)or in case of plastic vessels to the next ground potential.
For this purpose there is a ground terminal on the side of the
instrument housing.
For power supply,an approved installation cable with PE conductor is
necessary.
The 4…20 mAcurrent output 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.

5Connecting to power supply
28778-EN-081127

If screened cable is necessary,connect the cable screen on both ends
to ground potential.In the sensor,the screen must be connected
directly to the internal ground terminal.The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
If potential equalisation currents are expected,the connection on the
processing side must be made via a ceramic capacitor (e.g.1nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed,but the protective effect against high frequency interfer-
ence signals remains.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
With the Exd version,the minus side of the signal output is galvanically
connected to ground via protective diodes.When connecting the
instrument to a grounded PLC,equalising currents can flow in case of
potential differences which can cause malfunctions.Make sure that
there is sufficient potential equalisation from the system side or realise
the connection via switching amplifier.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2Loosen compression nut of the cable entry
3Remove approx.10 cm (4in)of the cable mantle (current output),
strip approx.1cm (0.4in)insulation from the ends of the individual
wires
4Insert the cable through the cable gland into the sensor
5Lift the opening levers of the terminals with a screwdriver
6Insert the wire ends into the open terminals according to the wiring
plan
7Press down the opening levers of the terminals,you will hear the
terminal spring closing
8Check the hold of the wires in the terminals by lightly pulling on
them
9Connect the screen to the internal ground terminal,connect the
outer ground terminal with potential equalisation
10 Tighten the compression nut of the cable entry.The seal ring must
completely encircle the cable
11 Connect the lead cable for power supply in the same way
according to the wiring plan,in addition connect the ground
conductor to the inner ground terminal.
