2For your safety
2.1Authorised personnel
All operations described in this operating instructions manual
must be carried out only by trained specialist 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.
2.2Appropriate use
VEGASWING 51 is a sensor for level detection.
Detailed information on the application range of VEGASWING
51 is available in chapter "Product description".
2.3Warning 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.
2.4General safety instructions
VEGASWING 51 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.
2.5CE conformity
VEGASWING 51 is in CE conformity with EMC (89/336/EWG),
fulfils NAMUR recommendation NE 21 and NE 23 and is in CE
conformity with NSR (73/23/EWG).
Conformity has been judged according to the following
standards:
lEMC:
-Emission EN 61326:1997 (class B)
-Susceptibility EN 61326:1997/A1:1998
lLVD:EN 61010-1:2001

2.6Manufacturer declaration
In conformity with DIN EN 60079-14/2004,para.5.2.3,point
c1,VEGASWING 51 is suitable for use in zone 2.
The operator must use the instrument as it was intended to be
used and follow the specifications of the following documents:
lthis operating instructions manual
lthis manufacturer declaration (24625)
lthe applicable installation regulations
Max.increase of the surface temperature during operation:
82 K(individual components in the instrument)
With an ambient temperature of 70 °C(158 °F)on the housing
and a process temperature of 70 °C(158 °F), the max.ambient
temperature during operation is 135 °C(275 °F).
Measures to maintain explosion protection during operation:
lOperate the instrument in the range of the specified
electrical limit values.Permissible supply voltage:see
"Technical data"
lMount and operate the instrument in such a way that
ignition danger by electrostatic charge is not expected.
lMake sure that no explosive atmosphere exists when the
plug of the connection cable is pulled or plugged
lMake sure that the cable gland is tight and strain-relieved.
The outer diameter of the connection cable must be
adapted to the cable gland.Tighten the pressure screw of
the cable gland carefully.
lThe surface temperature of the housing must not exceed
the ignition temperature of the surrounding explosive
atmosphere
This instrument was assessed by a person who fulfils the DIN
EN 60079-14 requirements.
2.7Environmental instructions
Protection of the environment is one of our most important
duties.That is why we have introduced an environment
management system with the goal of continuously improving
company environmental protection.The environment man-
agement system is certified according to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the environ-
mental instructions in this manual:

3.2Principle of operation
VEGASWING 51 is a level sensor with tuning fork for level
detection.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
Typical applications are overfill and dry run protection.With a
tuning fork of only 40 mm length,VEGASWING 51 can be also
mounted,e.g.in pipelines from DN 25.The small tuning fork

allows use in vessels,tanks and pipes.Thanks to its simple
and robust measuring system,VEGASWING 51 is virtually
unaffected by the chemical and physical properties of the
liquid.
It functions even under difficult conditions such as turbulence,
air bubbles,foam generation,buildup,strong external vibration
or changing products.
Fault monitoring
The electronics module of VEGASWING 51 continuously
monitors via frequency evaluation the following criteria:
lStrong corrosion or damage on the tuning fork
lloss of vibration
lLine break to the piezo drive
If a malfunction is detected or in case of power failure,the
electronics takes on a defined switching condition,i.e.the
contactless electronic switch opens (safe condition).
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx.1200 Hz.The
piezos are fixed mechanically and are hence not subject to
temperature shock limitations.The frequency changes when
the tuning fork is covered by the medium.This change is
detected by the integrated oscillator and converted into a
switching command.
VEGASWING 51 is a compact instrument,i.e.it can be
operated without external evaluation system.The integrated
electronics evaluates the level signal and outputs a switching
signal.With this switching signal,a connected device can be
operated directly (e.g.a warning system,aPLC,a pump etc.).
The data for power supply are stated in chapter "Technical
data"in the "Supplement".
3.3Operation
The switching status of VEGASWING 51 can be checked with
closed housing (signal lamp). Products with a density >0.7g/
cm³(>0.025 lbs/in³)can be detected.
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.
