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.
Power is supplied via the H1Fieldbus.Atwo-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors.This cable can be operated in two versions:
lvia an H1interface card in the control system and additional power
supply
lvia a Linking device
with HSE (High speed
Ethernet)and addition-
al power supply ac-
cording to IEC 61158-2
The DD (Device Descriptions)and CFF (capability files)necessary for
planning and configuration of your FF (Foundation Fieldbus)commu-
nication network are available in the download area of the VEGA
homepage www.vega.com under "Services -Downloads -Software -
Foundation Fieldbus".The appropriate certificates are also available
there.A CD with the appropriate files and certificates can be ordered
via e-mail under [e-mail] 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 power 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 instruments.

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.
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.

28790-EN-081127

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 according to Foundation Fieldbus specification
Tip:
We recommend VEGA overvoltage arrester B63-32.
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the sensors
and power supply units.
The instrument requires a operating voltage of 9…32 V DC.
Operating voltage and the digital bus signal are carried on the same
two-wire connection cable.Power is supplied via the H1power supply.
Connection is carried out with screened cable according to Fieldbus
specification.
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.
Make sure that the entire installation is carried out according to the
Fieldbus specification.In particular,make sure that the termination of
the bus is done with appropriate terminating resistors.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
Caution:
No grease should be used when screwing the NPT cable gland or
steel tube into the threaded insert.Standard grease can contain
additives that corrode the connection between threaded insert and
housing.This would influence the stability of the connection and the
tightness of the housing.
In systems with potential equalisation,connect the cable screen
directly to ground potential at the power supply unit,in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).

5Connecting to power supply
28790-EN-081127

In systems without potential equalisation,connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor,the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential 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 interference signals remains.
The total capacitance of the cable and of all capacitors must not exceed
10 nFin Ex applications.
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.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove it by
turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip approx.
1cm (0.4in)insulation from the ends of the individual wires
5Insert the cable through the cable gland into the sensor
6Lift the opening levers of the terminals with a screwdriver (see
