3.2 Principle of operation
OPTISOUND 3030 C is an ultrasonic sensor for continuous level
measurement. It is suitable for liquids and solids in practically all
industries.
The transducer of the ultrasonic sensor transmits short ultrasonic
pulsestothemeasuredproduct.Thesepulsesarereectedby
medium 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 is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbusspecicationservesascarrierofbothpoweranddigitaldata
for multiple sensors. This cable can be operated in two versions:
• via an H1 interface card in the control system and additional power
supply
• viaaLinkingdevicewithHSE(HighspeedEthernet)andaddi-
tional power supply according to IEC 61158-2
TheDD(DeviceDescriptions)andCFF(capabilityles)necessary
forplanningandcongurationofyourFF(FoundationFieldbus)com-
munication network are available in the download area.
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speciedinchapter"Technical data".
3.3 Packaging, transport and storage
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 must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
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
Select an installation position you can easily reach for mounting and
connectingaswellaslaterretrotting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
dierent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gland.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.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Fig. 2: Measures against moisture ingress
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
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

These can, however, be suppressed by an appropriate adjustment
(see chapter "Setup").
If this distance cannot be maintained, a false signal suppression
should be carried out during setup. This applies particularly if buildup
on the vessel wall is expected. In such cases, we recommend repeat-
ing the false signal suppression at a later date with existing buildup.

Fig.10:Beamdeector
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 signal suppression
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baesabovetheinstallations
scatter the ultrasonic signals and avoid direct false echoes.

Throughtheactionoflling,stirringandotherprocessesinthevessel,
dense foams which considerably damp the emitted signals may form
on the medium 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unaectedbyfoamgenerationandisparticu-
larly 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OPTISOUND3030Cinastandpipeoruseadier-

5.1 Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
• The electrical connection must only be carried out by trained,
qualiedpersonnelauthorisedbytheplantoperator.
• If overvoltage surges are expected, overvoltage arresters should
be installed.
Theinstrumentrequiresaoperatingvoltageof9…32VDC.Operat-
ing voltage and the digital bus signal are carried on the same two-wire
connection cable. Power is supplied via the H1 power supply.
Connection is carried out with screened cable according to Fieldbus
specication.
Makesurethatthecableusedhastherequiredtemperatureresist-
anceandresafetyformax.occurringambienttemperature
Use cable with round cross section for instruments with housing and
cablegland.Toensurethesealeectofthecablegland(IPprotection
rating),ndoutwhichcableouterdiameterthecableglandissuitable
for.
Useacableglandttingthecablediameter.
Makesurethattheentireinstallationiscarriedoutaccordingtothe
Fieldbusspecication.Inparticular,makesurethatthebusistermi-
nated with suitable terminating resistors.
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inuencethestabilityoftheconnectionandthe
tightness of the housing.
In systems with potential equalisation, connect the cable screening
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 screening 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.1nF,1500V).The
low frequency potential equalisation currents are thus suppressed,

buttheprotectiveeect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.
