3.2 Principle of operation
Area of application
Physical principle
Power supply
OPTISOUND 3040 C is an ultrasonic sensor for continuous
level measurement. It is particularly suitable for solids, but is
also good for liquids.
The transducer of the ultrasonic sensor emits short ultrasonic
pulses in the direction of the measured product. These pulses
are reflected by the product surface and received by the
transducer as echoes. The running time of the ultrasonic
pulses from emission to reception is proportional to the
distance and hence to 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 power supply range can differ depending on the instru-
ment version. The exact range is stated in the "Technical data"
in the "Supplement".
Measured value transmission is carried out via the 4 ... 20 mA/
HART output, which is separated from the power supply.
3.3 Adjustment
OPTISOUND 3040 C can be adjusted with two different
adjustment media:
l the indicating/adjustment module
l a HART handheld
The entered parameters are generally saved in OPTISOUND
3040 C, optionally also in the indicating/adjustment module.

4.1 General instructions
Installation position
Moisture
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 cable (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your OPTISOUND 3040 C 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 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
Measuring range
The reference plane for the measuring range (version A) is the
lower edge of the flange. The reference plane for versions B, C
and D is the lower edge of the transducer.

Mounting
Make sure that for all versions 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 the Technical data in the Supplement.
Information:
If the product reaches the transducer, buildup can form on it
over a period of time and later cause measurement errors.

Gauge pressure in the vessel does not influence OPTISOUND
3040 C. Low pressure or vacuum, 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 radar (TDR).

4.3 Mounting information
Installation position
16 OPTISOUND 3040 C - 4 ... 20 mA/HART - four-wire
When mounting OPTISOUND 3040 C, keep a distance of at
least 500 mm to the vessel wall. If the sensor is installed in the
center of concave or arched vessel tops, multiple echoes can
arise. These can, however, be faded out by an appropriate
adjustment (see chapter "Setup").
30515-EN-050914
Page 17
Mounting
If this distance cannot be maintained, a false echo storage
should be carried out during setup. This applies particularly if
buildup on the vessel wall is expected. In this case, we
recommend repeating the false echo storage later on with
existing buildup.

> 500 mm
Fig. 8: Installation position

In vessels with conical bottom it can be advantageous to align
the sensor to the center of the vessel, as measurement is then
possible down to the lowest points of the vessel bottom.

Mounting
Socket
Sensor orientation
Vessel installations
The transducer should be mounted preferably without socket,
flush with the vessel top.
If the reflective properties of the medium are good, you can
mount OPTISOUND 3040 C on a socket piece. The socket
end should be smooth and burr-free, if possible also rounded.
Carry out a false echo storage.
In liquids, direct the sensor as perpendicular as possible to the
product surface to achieve optimum measurement results.
Fig. 10: Orientation in liquids
To optimally align the sensor to solid products, a swivelling
holder can be implemented.
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.
If there are 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
Material heaps
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.
Fig. 12: Agitators
Large material heaps are detected with several instruments,
which can be mounted on e.g. traverse cranes. For this type of
application, it is best to orient the sensor toward the solid
surface.

Inflowing material
Foam
Do not mount the instruments in or above the filling stream.
Make sure that you detect the product surface and not the
inflowing product.
Fig. 14: Inflowing material
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 not influenced by foam generation and is
particularly suitable for such applications.

Air flow
Heat fluctuations
If there are strong air currents in the vessel, e.g. due to strong
winds in outdoor installations, or because of air turbulence, e.
g. through cyclone exhausting, you should mount OPTI-
SOUND 3040 C in a standpipe or use a different measuring
principle, e.g. radar or guided radar (TDR).
Strong heat fluctuations, e.g. caused by the sun, can cause
measurement errors. In this case, you should use a sun shield.

Connecting to power supply
5 Connecting to power supply
5.1 Preparing the connection
Note safety instructions
Take note of safety
instructions for Ex
applications
Select power supply
Selecting the connection ca-
ble
Always observe the following safety instructions:
l Connect only in the complete absence of line voltage
l If overvoltages are expected, overvoltage arresters should
be installed.
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
Power supply and current output are transmitted via separate
two-wire connection cables. The power supply range can differ
depending on the instrument version. The exact range is
stated in the "Technical data" in the Supplement.
The standard version can be operated with an earthconnected 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 OPTISOUND 3040 C to vessel ground
(potential equalisation), or in case of plastic vessels, to the
next ground potential. 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 mA current output is connected with standard twowire cable without screen. An outer cable diameter of 5 ...
9 mm ensures the seal effect of the cable entry. If electromagnetic interference is expected, we recommend the use of
screened cable.
Cable screening and grounding
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 outside on the
housing must be connected to the potential equalisation (low
impedance).

30515-EN-050914
Page 23
Connecting to power supply
If potential equalisation currents are expected, the connection
on the evaluation 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 interference signals remains.
Select connection
cable for Ex applica-
tions
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.
5.2 Connection procedure
Proceed as follows:
1 Unscrew the housing cover
2 Loosen compression nut of the cable entry
3 Remove approx. 10 cm (4 in) of the cable mantle (current
output), strip approx. 1 cm (0.4 in) insulation from the ends
of the individual wires
4 Insert the cable into the sensor through the cable entry
5 Lift the opening levers of the terminals with a screwdriver
6 Insert the wire ends into the open terminals according to
the wiring plan
7 Press down the opening levers of the terminals, you will
hear the terminal spring closing
8 Check the hold of the wires in the terminals by lightly
pulling on them
9 Connect the screen to the internal ground terminal and the
external ground terminal to 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
acc. to the wiring plan, in addition connect the ground
conductor to the inner ground terminal.
12 Screw the housing cover back on
The electrical connection is finished.

Because OPTISOUND 3040 C is a distance measuring
instrument, its primary task is to measure the distance from the
sensor to the product surface. In order to indicate the actual
filling level, the measured distance must be allocated to a
specific height percentage. To make this adjustment, the full
and empty distances in the vessel are entered. If these values
are not known, it is also possible to carry out the adjustment
with other distances, e.g. 10 % and 90 %. The origin of these
distance values is always the lower edge of the flange (with
flange versions) or the lower edge of the transducer (all other
versions).
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:

Medium selection
Each product has different reflective properties. In addition,
there are various interfering factors which have to be taken into
account: agitated product surfaces and foam generation (with
liquids); dust generation, material cones and echoes from the

conditions, you should first select in this menu item "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 bad reflective properties, is considerably
increased.
Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [–>] key.
Vessel shape
Damping
Apart from the medium, the shape of the vessel can also
influence the measurement. To adapt the sensor to these
conditions, this menu item offers (depending on either liquid or
solid is detected) different options. For Liquid these are
Storage tank, Stilling tube, Open vessel or Stirred vessel, for
Solid Silo or Bunker

Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [–>] key.
To suppress fluctuation in the measured value display, e.g.
caused by a turbulent product surface, an integration time can
be set. This time can be between 0 and 999 seconds. Please
note that the reaction time of the entire measurement will be
longer and the sensor will react to quick changes of the
measured value with a corresponding delay. In general, a time
of a few seconds is sufficient to smooth the measured value
display.

Linearization curve
Sensor-TAG
A linearization is necessary for all vessels in which the vessel
volume does not increase linearly with the level – e.g. in a
cylindrical or spherical tank -–and the indication or output of
the volume is requested. Corresponding linearization 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".

Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [–>] key.
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 identification of individual measuring sites.

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 signal suppression detects, marks and saves
these false signals, so that they are no longer taken into
account for the level measurement. This false signal suppression should be created with empty vessel so that all
potential interfering reflections will be detected.

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 false signal. The filling level would then no longer be
detectable in this area.

Additional adjustment and diagnosis options such as e.g.
scaling, simulation or trend curve presentation are shown in
