For your safety
2 For your safety
2.1 Authorised personnel
All operations described in this operating instructions manual
must be carried out only by trained, specialised personnel
authorised by the operator. For safety and warranty reasons,
any internal work on the instruments must be carried out only
by personnel authorised by the manufacturer.
2.2 Appropriate use
OPTISOUND 3040 C is a sensor for continuous level
measurement.
2.3 Warning about misuse
Inappropriate or incorrect use of the instrument can give rise to
application-specific hazards, e.g. vessel overfill or damage to
system components through incorrect mounting or adjustment.
2.4 General safety instructions
OPTISOUND 3040 C is a high-tech instrument requiring the
strict observance of standard regulations and guidelines. The
user must take note of the safety instructions in this operating
instructions manual, the country-specific installation standards
(e.g. the VDE regulations in Germany) as well as all prevailing
safety regulations and accident prevention rules.
2.5 CE conformity
OPTISOUND 3040 C is in CE conformity with EMC (89/336/
EWG) and NSR (73/23/EWG).
Conformity has been judged acc. to the following standards:
l EMC:
- Emission EN 61326: 1997 (class A)
- Susceptibility EN 61326: 1997/A1: 1998
l LVD: EN 61010-1: 2001
OPTISOUND 3040 C is designed for industrial use. Hence,
conducted as well as radiated interference must be reckoned
with, as is customary with a class A instrument acc. to EN
61326. If OPTISOUND 3040 C is used in a different environ-
ment, the electromagnetic compatibility to other instruments
must be ensured by suitable measures.

For your safety
2.6 Compatibility acc. to NAMUR NE 53
OPTISOUND 3040 C meets NAMUR recommendation NE 53.
The parameter adjustment of the basic sensor functions is
independent of the software version. The range of available
functions depends on the respective software version of the
individual components.
The software version of OPTISOUND 3040 C can be
determined as follows:
l on the type label of the electronics
l via the indicating/adjustment module.
You can find all software histories on our website www.krohne.

Product description
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.
3.4 Storage and transport
Packaging
Storage and transport tem-
perature

Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc. to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.

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.
10 OPTISOUND 3040 C - 4 ... 20 mA/HART - four-wire
30515-EN-050914
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).

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").
