3.2 Principle 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.
Functional principle
28785-EN-130417
VEGASON 62 • Probus PA
The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reected by
7
3 Product description
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.
Power supply and bus
communication
GSD/EDD
Power supply via the Probus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Probus specication
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument prole of VEGASON 62 corresponds
to prole specication version 3.0.
The backlight of the display and adjustment module is powered by the
sensor. Prerequisite is a certain level of operating voltage.
The data for power supply are specied in chapter "Technical data".
The optional heating requires its own operating voltage. You can nd
details in the supplementary instructions manual "Heating for display and adjustment module".
This function is generally not available for approved instruments.
The GSD (instrument master les) and bitmap les necessary for
planning your Probus-DP-(PA) communication network are available
from the download section on the VEGA homepage www.vega.com
under "Services-Downloads-Software-Probus". There you can
also nd the appropriate certicates. In a PDM environment, an EDD

Installation position
Moisture
Measuring range
Select an installation position you can easily reach for mounting and
connecting as well as later retrotting 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
dierent 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 o. 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 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".

Gauge pressure in the vessel does not inuence VEGASON 62. Low
pressure or vacuum does, however, damp the ultrasonic pulses. This
inuences the measuring result, particularly if the level is very low.
With pressures under -0.2 bar (-20 kPa) you should use a dierent
measuring principle, e.g. radar or guided microwave.
4.2 Mounting instructions
Screw VEGASON 62 into the mounting socket with an appropriate
spanner applied to the hexagon of the process tting. 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.

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").

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 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 62 with a beam deector. By doing this, it is possible to ll the
vessel nearly to maximum. Such an arrangement is suitable primarily
for open vessels such as e.g. overow basins.

Vessel installations
Agitators
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 baes above the installations
scatter the ultrasonic signals and avoid direct false echoes.

If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfering reections from the agitators are saved with the blades in dierent
positions.

Do not mount the instruments in or above the lling stream. Make sure
that you detect the product surface, not the inowing product.
Fig.13:Inowingliquid
Through the action of lling, 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 wave radar is unaected 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 dierent
measuring principle, e.g. radar or guided radar (TDR).

Always keep in mind the following safety instructions:
Connect only in the complete absence of line voltage
•
If voltage surges are expected, overvoltage arresters should be
•
installed according to Probus specications
Tip:
We recommend VEGA overvoltage arrester B63-32.

28785-EN-130417
VEGASON 62 • Probus PA
Power is supplied via a Probus DP/PA segment coupler or a VEGALOG 571 EP input card. The power supply range can dier depending
on the instrument version.
The data for power supply are specied in chapter "Technical data".
Connection is made with screened cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent diameter or cross-section,
exchange the seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the
Probus specication. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.
On the instrument with cable entry ½ NPT 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 inuence the stability of the connection and the
tightness of the housing.
With 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).
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
17
5 Connecting to power supply
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The
low frequency potential equalisation currents are thus suppressed,
but the protective eect against high frequency interference signals
remains.
The total capacitance of the cable and of all capacitors must not
exceed 10 nF in Ex applications.
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
ow 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 turning 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

Approx. 10 minutes after the last pressing of a key, an automatic reset
to measured value indication is triggered. Any values not conrmed

6.4 Setup steps
Before starting the actual parameter adjustment of a Probus PA
sensor, the address setting must rst be carried out. You will nd a
detailed description in the operating instructions manual of the display
and adjustment module or in the online help of PACTware or DTM.
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 specications is
always the lower side of the ange, 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, because the min./max. adjustment is always carried out without changing the product level. These settings can be made ahead of time
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:

Through this additional selection, the sensor is adapted perfectly to
the product and measurement reliability, particularly in products with
poor reective 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
Damping
Linearization curve
Apart from the medium, the vessel shape can also inuence the
measurement. To adapt the sensor to these measuring conditions,
this menu item oers dierent options depending on whether liquid
or bulk solid is selected. With "Liquids" these are "Storage tank",
"Stillingtube", "Open vessel" or "Stirred vessel", with "Solid", "Silo" or
"Bunker".
Vessel form
Storage tank
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
To suppress uctuations 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 sucient to smooth the measured value display.
Damping

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindrical 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 percentage and vessel volume. By activating the appropriate curve, the
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".

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

With this menu item, the Basic adjustment is nished and you can
now jump to the main menu with the [ESC] key.
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
reections 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 reections can be detected.
False signal suppression
Change now?
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 conrm with [OK].
Now the menu item "False signal suppression" is displayed.
3. Conrm "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 conrming 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 lling level would then no longer be detectable in this area.

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.
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".

10 Supplement
A bitmap le is also provided for the Probus network planning tool. This le is installed automatically when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instrument in the conguration tool.
Ident number
Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user
organisation (PNO). This ID number is also included in the name of the GSD le. For VEGASON 62
the ID number is 0x0770(hex) and the GSD le "SN__0770.GSD". As an option to this manufacturer-specic GSD le, PNO provides also a general so-called prole-specic GSD le. For VEGASON
62 you have to use the general GSD le "PA139701.GSD". If the general GSD le is used, the
sensor must be set to the prole-specic ident number via the DTM software. By default, the sensor
operates with the manufacturer-specic ID number.
Note:
When using the prole-specic GSD le, the PA-OUT value as well as the temperature
value are transmitted to the PLC (see block diagram "Cyclicaldatatrac").

A maximum of three modules can be active. By means of the conguration software of the Probus
master you can determine the conguration of the cyclical data telegram with these modules. The
procedure depends on the respective conguration software.
Note:
The modules are available in two versions:
Short for Probus master supporting only one "Identier Format" byte, e.g. Allen
•
Bradley
Long for Probus master only supporting the "Identier Format" byte, e.g. Siemens
•
S7-300/400

The status byte corresponds to prole 3.0 "Probus PA Prole for Process Control Devices" coded.
The status "Measured value OK" is coded as 80 (hex) (Bit7 = 1, Bit6 … 0 = 0).
The measured value is transferred as a 32 bit oating point number in the IEEE-754 format.
