Safety and responsibility Instruction for use
1. Safety and responsibility
1.1 Intended use
The 2260 Ultrasonic Level Transmitters are an excellent tool for the level measurement of liquids. Level
measurement technology based on the non-contacting ultrasonic principle is especially suited for
applications where, for any reason, no physical contact can be established to the surface of the material
to be measured. Such reasons may include corrosive attack by the process medium against the
measuring device material (acids), possible contamination (sewage) or particles of the process medium
adhering to the measuring device (adhesive materials).
1.2 Safety regulations for the Ex approved units
The 2260 Ultrasonic Level Transmitter must be operated in intrinsically safe circuit only, see values in
chapter “Technical Data”. For temperatures see values in “Techical Data”. Transducer head are made of
plastic tending to charge up electrostatically, thus:
The velocity of the filling and discharging process must be chosen according to the medium.
During filling the material causing the hazard must be hindered from forming a mist
It is not permitted to clean the plastic cover in explosion hazardous area
The apparatus is not suitable for flame-proof enclosure towards the external area.
2. Transport and storage
Transport and/or store product in unopened original packaging.
Protect product from dust, dirt, dampness as well as thermal and UV radiation.
Make sure that the product has not been damaged neither by mechanical nor thermal influences.
Check product for transport damages prior to the installation.
3. Design and function
3.1 Design
3
Instruction for use Design and function
3.2 Function
The ultrasonic level metering technology is based on the principle of measuring the time required for the
ultrasound pulses to make a round trip from the sensor to the level to be measured and back. The sensor
emits an ultrasonic pulse train and receives the echoes reflected. The intelligent electronic device
processes the received signal by selecting the echo reflected by the surface and calculates from the time
of flight the distance between the sensor and the surface which constitutes the basis of all output signals
of the 2260 Ultrasonic Level Transmitter.
A Total beam angle of 5°-7° at –3 dB as is featured by transducers of transmitters and sensores ensuring
a reliable measurement in narrow silos with uneven side walls as well as in process tanks with various
protruding objects.
Furthermore, as a result of the narrow beam angle - the emitted ultrasonic signals have an outstanding
focusing - deep penetration through gases, vapour and foam is ensured.

Design and function Instruction for use
Minimum measuring distance (Xm) (Dead Band) is determined by the design of the unit within which the
measurement is not possible (Dead Zone). This distance can be extended by programming in order to
avoid disturbing effects of possible disturbing echoes coming from fixed objects. (Close-end Blocking)..
Maximum measuring distance (X
) is the greatest distance (determined by the design of the unit) which
M
can be measured by the unit under ideal conditions. The maximum measuring distance of the actual
application (H) must not be greater than X
.

4.3 Maintenance and repair
The 2260 Ultrasonic Level Transmitters do not require maintenance on a regular basis. In some very rare
instances, however, the transducer may need a cleaning from deposited material. This must be carried
out gently, without scratching or pressing the surface of the transducer.
Repairs during or after the warranty period are carried out exclusively at the Manufacturers. The
equipment sent back for repairs should be cleaned or neutralised (disinfected) by the User.

Instruction for use Installation
5. Installation
5.1 Liquid Level Measurement
Position
The optimal position of the 2260 Ultrasonic
Level Transmitter is on the radius
r = (0.3 … 0.5) R of the (cylindrical) tank / silo.
(Take also sonic cone on page 1 into
consideration.)
Sensor alignment
The sensor face has to be parallel to the surface of the liquid
within ± 2-3°.
Temperature
Make sure that the 2260 Ultrasonic Level Transmitter will be
protected against overheating by direct sunshine.
Sonnenschirm
Obstacles
Make sure that no in-flow path or objects (e.g. cooling pipes,
ladders, bracing members, thermometers, etc.) or no tank wall of
the ragged surface protrude into the sensing cone of the
ultrasonic beam.
One fix object in the tank / silo that disturb the measurement can
be blocked out by the appropriate programming of the 2260
Ultrasonic Level Transmitters – see Parameter P29 “Blocking out
of disturbing object”
Foam
Foaming of the liquid surface may render ultrasonic level metering impossible. If possible, a location
should be found, where foaming is the least (device should be located as far as possible from liquid
inflow) or a stilling pipe or well should be used.

Installation Instruction for use
Stand-off-Pipe
The structure of the stand off pipe should be rigid; the inner rim where the ultrasonic beam leaves the
pipe should be rounded.

Note: The mentioned values are indications.
Depending on the assembling conditions larger
diameters are to be considered.
Wind
Intensive air (gas) movements in the vicinity of the ultrasonic cone is to be avoided. A strong draft of
wind may "blow away" the ultrasound. Devices with lower measuring frequency (40, 20 kHz) are
recommended.
Fumes/ Vapours
For closed tanks containing chemicals or other liquids, which creats fume/gases above the liquid
surface especially for outdoor tanks exposed to the sun, a strong reduction of the nominal measuring
range of the ultrasonic device is to be considered during device selection.
Devices with lower measuring frequency (40, 20 kHz) are recommended in these cases units.

5.2 Installation and electrical connection
5.2.1 Installation of the (BSP or NPT) threaded models
Screw the unit in to its place. Use open wrench for tightening; max torque is 20Nm

1
After tightening the enclosure can be rotated to the proper position. (Safety bolt prevents rotation
more than 350°)
The unit may be damaged by electrostatic discharge (EDS) via its terminal, thus apply the
precautions commonly used to avoid electrostatic discharge e.g. by touching a properly grounded
point before removing the cover of the enclosure.
Ensure that the power supply is turned off at the source.
With removal of the cover of the housing and taking out the display module (if any), the screw
terminals can be accessed. Suggested cable core cross section:
0.5 ... 1.5 mm
Switch on the unit and make necessary programming.
After programming ensure proper sealing and closing of the cover.

Programming in general Instruction for use
6. Programming in general
The 2260 Ultrasonic Level Transmitters can be programmed by the following two ways:
1. Programming without Display Module, see 6.1
Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal
and damping can be set.
2. With Display Module, see 6.2
All features of the unit can be set, such as measurement configuration and optimisation, 32-point
linearisation, dimensions for 11 tanks with different shape and for 21 different open channels (flume,
weir, etc).
The devices are already equipped with the display module. The 2260 Ultrasonic Level Transmitter is fully
operational without the display module. It is only needed for programming and/or displaying
measurement values.
The unit will measure during programming in accordance with the previous parameters. The new,
modified parameters will only be effective after returning to the Measurement Mode
If the 2260 Ultrasonic Level Transmitter is left in Programming Mode by mistake, it will
automatically return to Measurement Mode after 30 minutes and will operate with the
parameters entered during the last completed programming. The 2260 Ultrasonic Level
Transmitter will be delivered with the following Factory Default:
• Current output, display and bargraph: LEVEL
• 4 mA: assigned to the minimum level 0%
• 20 mA: assigned to the maximum level 100%
• Error indication by the current output: hold last value
• Damping: 60 sec
6.1 Programming without display module
Programming is only possible if the 2260 Ultrasonic Level Transmitter is in Level Measuring Mode and
receives valid echo i.e. “VALID” LED is lit. The following can be programmed without display module:
Assignment of the 4 mA to a required e.g. min. level / max.
distance
Assignment of the 20 mA to a required e.g. max. level /
min. distance
Error indication by the current output (Hold, 3.6 mA or
22 mA)
Damping (10, 30 or 60 sec)
Reset to the factory default
Note: Current output can also be assigned in inverted mode:
4 mA = 100% (Full), 20 mA = 0% (Empty)
