3.2 Principle of operation

Application area VEGASON 62 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.

Functional principle The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reflected by
product surface and received back 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.
Voltage supply 4 … 20 mA/HART two-wire electronics for voltage supply and meas-
ured value transmission on the same cable.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
The optional background lighting of the display and adjustment
module is powered by the sensor. A certain level of operating voltage
is required for this. You can find the exact voltage specifications in
chapter "Technical data".
The optional heating requires its own operating voltage. You can find
details in the supplementary instructions manual "Heating for display
and adjustment module".
This function is generally not available for approved instruments.
3.3 Operation
The instrument can be adjusted with the following adjustment media:
• With the display and adjustment module
• with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
• with manufacturer-specific adjustment programs AMS™ or PDM
• With a HART handheld
3.4 Packaging, transport and storage

Packaging Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
28776-EN-130417
Transport inspection The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.

4.1 General instructions
Suitability for the process Make sure that all parts of the instrument coming in direct contact
conditions with the process, 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" and on the
nameplate.
Installation position Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of a display and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the display and adjustment module in four
different positions (each displaced by 90°).
Moisture 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 ap-
plies 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
Measuring range The reference plane for the measuring range is the lower edge of the
transducer.
Make sure that a minimum distance from the reference plane - the
so-called dead band, in which measurement is not possible - is
maintained. The exact value of the dead band is stated in chapter
"Technical data".

Pressure/Vacuum 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 -0.2 bar (-20 kPa) you should use a different
measuring principle, e.g. radar or guided microwave.
4.2 Mounting instructions

Screwing in Screw VEGASON 62 into the mounting socket with an appropriate
spanner applied to the hexagon of the process fitting. Max. torque see
28776-EN-130417
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.

4 Mounting
Installation position 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").
> 200 mm
Fig. 5: Mounting on round vessel tops

1 Reference plane
2 Vessel 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 stor-
age 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.
28776-EN-130417
Fig. 6: Vessel with conical bottom
Socket Socket pieces should be dimensioned so that the lower end of the
transducer protrudes at least 10 mm (0.394 in) out of the socket.

ca. 10 mm
Fig. 7: Recommended socket mounting
If the reflective properties of the medium are good, you can mount
VEGASON 62 on sockets which are higher than the length of the
transducer. 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.

Sensor orientation Align the sensor in liquids as vertical as possible to the product sur-
face to achieve an optimum measurement result.
Fig. 9: Alignment in liquids
To reduce the min. distance to the medium, you can also mount VE-
GASON 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.

Vessel installations 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, heat-
ing 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.

Agitators If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfer-
ing reflections from the agitators are saved with the blades in different
positions.
28776-EN-130417

4 Mounting
Fig. 12: Agitators
Inflowing medium 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
Foam 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 sen-
sors (TDR) should be used.
Guided wave radar is unaffected by foam generation and is particu-
larly suitable for such applications.
Air turbulences If there are strong air currents in the vessel, e.g. due to strong winds
28776-EN-130417
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).

4 Mounting
Standpipe measurement 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.

VEGASON 62 can be used from tube diameters of 50 mm (1.969 in).

Avoid large gaps and thick welding joints when connecting the tubes.
Generally carry out a false echo storage.
Measurement in a standpipe is not recommended for extremely
adhesive products.
28776-EN-130417


5.1 Preparing the connection
Safety instructions Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If 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 must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
Voltage supply Power supply and current signal are carried on the same two-wire
cable. The voltage supply range can differ depending on the instru-
ment version.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1. The VEGA
power supply units VEGATRENN 149A Ex, VEGASTAB 690 as well
as all VEGAMETs and VEGASCANs meet this requirement.
Keep in mind the following additional factors that influence the operat-
ing voltage:
• Output voltage of the power supply unit can be lower under nomi-
nal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Influence of additional instruments in the circuit (see load values in
chapter "Technical data")
Connection cable 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. A cable outer diameter of
5 … 9 mm (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.
We generally recommend the use of screened cable for HART multi-
drop mode.
Cable gland ½ NPT On the instrument with cable entry ½ NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
28776-EN-130417
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.
Cable screening and If screened cable is necessary, connect the cable screen on both
grounding 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 equalisa-
tion (low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low-frequency potential equalisation currents are thus
suppressed, but the protective effect against high frequency interfer-
ence signals remains.
Warning:
Considerable potential differences exist inside galvanic plants as well
as vessels with cathodic corrosion protection. Very large equalisa-
tion currents can flow through the cable screen when the screen
is grounded on both ends. To avoid this, the cable screen must be
connected to ground potential only on one end (inside the switch-
ing cabinet) in such applications. The cable screen must not be
connected to the internal ground terminal in the sensor and the outer
ground terminal on the housing not to potential equalisation!
Information:
The metallic parts of the instrument (transmitter, process fitting, etc.)
are conductively connected with the inner and outer ground terminal
on the housing. This connection exists either as a direct metallic
contact or via the shielding of the special connection cable on instru-
ments with external electronics. You can find specifications on the po-
tential connections within the instrument in chapter "Technical data".
Take note of the corresponding installation regulations for Ex applica-
tions. 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.
5.2 Connection procedure

Proceed as follows:
1. Unscrew the housing cover
2. If a display and adjustment module is installed, remove it by turn-
ing it to the left.
3. Loosen compression nut of the cable entry
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry
28776-EN-130417
6. Lift the opening levers of the terminals with a screwdriver (see

following illustration)
7. Insert the wire ends into the open terminals according to the wir-
ing plan

Fig. 15: Connection steps 6 and 7
8. Press down the opening levers of the terminals, you will hear the
terminal spring closing
9. Check the hold of the wires in the terminals by lightly pulling on
them
10. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
11. Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
12. Screw the housing cover back on
The electrical connection is hence finished.

5.6 Switch-on phase

Switch-on phase After connecting VEGASON 62 to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds:
• Internal check of the electronics
• Indication of the instrument type, the firmware as well as the sen-
sor TAGs (sensor designation)
• Output signal jumps briefly (approx. 10 seconds) to the set fault
current
Then the corresponding current is outputted to the cable (the value
corresponds to the actual level as well as the settings already carried
out, e.g. factory setting).

6.4 Setup steps

Address setting HART In HART-Multidrop mode (several sensors on one input) the address
multidrop must be set before continuing with the parameter adjustment. You
will find a detailed description in the operating instructions manual
"Display and adjustment module" or in the online help of PACTware
or DTM.

Parameter adjustment As VEGASON 62 is a distance measuring instrument, the distance

from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 %
is also possible. Starting point for these distance specifications is
always the lower side of the flange, with all other versions the lower
side of the transducer.
The actual level is then calculated on the basis of these entered
values. At the same time, the operating range of the sensor is limited
from maximum range to the requested range.
The real product level during this adjustment is not important, be-
cause the min./max. adjustment is always carried out without chang-
ing the product level. These settings can be made ahead of time
28776-EN-130417
without the instrument having to be installed.

In the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.

Start your parameter adjustment with the following menu items of the
basic adjustment:
Carry out min. adjustment Proceed as follows:

1. Move from the measured value display to the main menu by
pushing [OK].

with [+] and save with [OK]. The cursor jumps now to the distance
value.
4. Enter the suitable distance value in m for the empty vessel (e.g.
distance from the sensor to the vessel bottom) corresponding to
the percentage value.
5. Save the settings with [OK] and move to "Max. adjustment" with
[->].
Carry out max. adjust- Proceed as follows:

1. Prepare the % value for editing with [OK] and set the cursor to the
requested position with [->]. Set the requested percentage value
with [+] and save with [OK]. The cursor jumps now to the distance
value.
2. Enter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. Keep in mind that the max.
level must lie below the dead band.
3. Save the settings with [OK] and move to "Medium selection" with
[->].
Medium selection Each product has different reflective properties. In addition, there
are various interfering factors which have to be taken into account:
28776-EN-130417
agitated product surfaces and foam generation (with liquids); dust

generation, material cones and echoes from the vessel wall (with
solids). To adapt the sensor to these different conditions, you should
first select "Liquid" or "Solid".

Medium
Liquid
With solids, you can also choose between "Powder/Dust", "Granular/

Pellets" or "Ballast/Pebbels".
Through this additional selection, the sensor is adapted perfectly to
the product and measurement reliability, particularly in products with
poor reflective properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
Vessel form Apart from the medium, the vessel shape can also influence the
measurement. To adapt the sensor to these measuring conditions,
this menu item offers different options depending on whether liquid
or bulk solid is selected. With "Liquids" these are "Storage tank",
"Stilling tube", "Open vessel" or "Stirred vessel", with "Solid", "Silo" or
"Bunker".
Vessel form
Storage tank
Damping To suppress fluctuations in the measured value display, e. g. caused

by an agitated product surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
the entire measurement will then be longer and the sensor will react
to measured value changes with a delay. In general, a period of a few
seconds is sufficient to smooth the measured value display.
Damping
0 s
Linearization curve A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage and vessel volume. By activating the appropriate curve, the
28776-EN-130417
volume percentage of the vessel is displayed correctly. If the volume

should not be displayed in percent but e.g. in l or kg, a scaling can be
also set in the menu item "Display".
Linearization curve

Linear
Sensor-TAG In this menu item you can enter an unambiguous designation for the
sensor, e.g. the measurement loop name or the tank or product des-
ignation. In digital systems and in the documentation of larger plants,
a singular designation should be entered for exact identification of
individual measuring points.

With this menu item, the Basic adjustment is finished and you can
now jump to the main menu with the [ESC] key.
False signal suppression High sockets or vessel installations, such as e. g. struts or agitators as
well as buildup and weld joints on the vessel walls, cause interfering
reflections which can impair the measurement. A false echo storage
detects and marks these false echoes, so that they are no longer
taken into account for the level measurement. A false echo memory
should be created with low level so that all potential interfering reflec-
tions can be detected.
False signal suppression

Proceed as follows:
1. Move from the measured value display to the main menu by
pushing [OK].
2. Select the menu item "Service" with [->] and confirm with [OK].
Now the menu item "False signal suppression" is displayed.
3. Confirm "False signal suppression - Change now" with [OK] and
select in the below menu "Create new". Enter the actual distance
from the sensor to the product surface. All false signals in this
area are detected by the sensor and saved after confirming with
[OK].
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
echo. The filling level would then no longer be detectable in this area.
28776-EN-130417
Extended setting/Quick The menu item "Extended setting" offers the possibility to optimise
level change VEGASON 62 for applications in which the level changes very quickly.
To do this, select the function "Quick level change > 1 m/min.".

Extended setting
quick level change > 1 m/min.
Note:
Since with the function "Quick level change > 1 m/min." the genera-
tion of an average value of the signal processing is considerably
reduced, false reflections by agitators or vessel installations can
cause measured value fluctuations. A false echo memory is thus
recommended.
Copy sensor data This function enables reading out parameter adjustment data as well
as writing parameter adjustment data into the sensor via the display
and adjustment module. A description of the function is available in
the operating instructions manual "Display and adjustment module".

6.10 Saving the parameter adjustment data

We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.
If VEGASON 62 is equipped with a display and adjustment module,
the most important data can be read out of the sensor into the display
and adjustment module. The procedure is described in the operating
instructions manual "Display and adjustment module" in the menu
item "Copy sensor data". The data remain there permanently even if
the sensor power supply fails.
28776-EN-130417
If it is necessary to exchange the sensor, the display and adjustment

module is inserted into the replacement instrument and the data are
written into the sensor under the menu item "Copy sensor data".

8.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
8.2 Rectify faults

Reaction when malfunc- The operator of the system is responsible for taking suitable meas-
tions occur ures to rectify faults.
Failure reasons VEGASON 62 offers maximum reliability. Nevertheless, faults can oc-
cur during operation. These may be caused by the following, e.g.:
• Sensor
• Process
• Voltage supply
• Signal processing
Fault rectification The first measures to be taken are to check the output signals as well
as to evaluate the error messages via the display and adjustment
module. The procedure is described below. Further comprehensive
diagnostics can be carried out on a PC with the software PACTware
and the suitable DTM. In many cases, the causes can be determined
and the faults rectified this way.
24 hour service hotline Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since

8.3 Exchanging the electronics module

If the electronics module is defective, it can be replaced by the user.
In Ex applications only one instrument and one electronics module
with respective Ex approval may be used.
If there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.
Sensor serial number The new electronics module must be loaded with the settings of the
sensor. These are the options:
• At the factory by VEGA
• Or on site by the user
In both cases, the sensor serial number is necessary. The serial num-
bers are stated on the type label of the instrument, inside the housing
or on the delivery note.
Information:
When loading on site, first of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics
