3.2 Principle 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
pulsestothemeasuredproduct.Thesepulsesarereectedby
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 is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbusspecicationservesascarrierofbothpoweranddigitaldata
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

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.
Uptothetimeofinstallation,thepackagesmustbeleftclosedand

You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the

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 ingress
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
protective 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.

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").

2 Vessel center or symmetry axis
If this distance cannot be maintained, a false signal storage should
be carried out during setup. This applies particularly if buildup on the
vessel wall is expected. In such cases, we recommend repeating the
false signal storage at a later date 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.

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
personnel authorised by the plant operator.
• If overvoltage surges are expected, overvoltage arresters should
be installed.
Theinstrumentrequiresaoperatingvoltageof9…32VDC.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
specication.
Usecablewithroundcrosssectionforinstrumentswithhousingand
cablegland.Toensurethesealeectofthecablegland(IPprotection

for.
Useacableglandttingthecablediameter.
Makesurethattheentireinstallationiscarriedoutaccordingtothe
Fieldbusspecication.Inparticular,makesurethatthebusistermi-
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.Thiswouldinuencethestabilityoftheconnectionandthe
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).
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. 1 nF, 1500 V). The
low frequency potential equalisation currents are thus suppressed,
buttheprotectiveeectagainsthighfrequencyinterferencesignals

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

5.2 Connection procedure
Proceed as follows:
1. Unscrewthehousinglid
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 gland
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.
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
6. Lift the opening levers of the terminals with a screwdriver (see

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