2.6SIL conformity
VEGAWAVE 63 meets the requirements to the functional
safety according to IEC 61508.Further information is available
in the Safety Manual "VEGAWAVE series 60".
2.7Safety instructions for Exareas
Please note the Ex-specific safety information for installation
and operation in Ex areas.These safety instructions are part of
the operating instructions manual and come with the Ex-
approved instruments.
2.8Manufacturer declaration
In conformity with DIN EN 60079-14/2004,para.5.2.3,point
c1,VEGAWAVE 63 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 (24659)
lthe applicable installation regulations
Max.increase of the surface temperature during operation:5K
(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 75 °C(167 °F).
Measures to maintain explosion protection during operation:
lfor connection to an amplifier according to NAMUR
IEC 60947-5-6,approx.8.2V
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 no
ignition danger is expected by electrostatic charges.The
process fitting,the plastic-coated/covered probe part or the
housing are made of electrically non-conductive plastic
(depending on the version).
lMake sure that the seal is mounted correctly between
lower part of the housing and cover.Screw the cover on
tightly.
lMake sure there is no explosive atmosphere present if you
intend to operate the instrument with opened cover

For your safety
32259-EN-070117

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.
lCover unused openings for cable glands tightly
lMount the instrument in such a way that the sensor cannot
touch the vessel wall or vessel installations.Keep in mind
the influence of product movement in the vessel.
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.
2.9Environmental 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:

Product description
32259-EN-070117

It is designed for industrial use in all areas of process
technology and is preferably used for bulk solids.
Typical applications are overfill and dry run protection.Thanks
to its simple and robust measuring system,VEGAWAVE 63 is
virtually unaffected by the chemical and physical properties of
the bulk solid.
It functions even when exposed to strong external vibration or
changing products.
Solid detection in water
IfVEGAWAVE 63 was ordered for detection of solids in water,
the tuning fork is adjusted to the density of water.In the air or
when covered by water (density:1g/cm³/0.036 lbs/in)
VEGAWAVE 63 signals "uncovered".Only if the vibrating
element is also covered with solids (e.g.sand,sludge,gravel
etc.) will the sensor signal "covered".
Fault monitoring
The electronics of VEGAWAVE 63 continuously monitors the
following criteria:
lCorrect vibrating frequency
lLine break to the piezo drive
If one of these faults is detected,the electronics signals this via
adefined current to the signal conditioning instrument.The
connection cable to the vibrating element is also monitored.
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx.150 Hz.When the
tuning fork is submerged in the product,the vibration
amplitude changes.This change is detected by the integrated
oscillator and converted into a switching command.
VEGAWAVE 63 with NAMUR electronics can be connected to
different NAMUR amplifiers depending on your requirements.
The specifications for NAMUR amplifiers are available in the
"Technical data".
The data for power supply are stated in chapter "Technical
data"in the "Supplement".
3.3Operation
With the factory setting,products with a density of >0.02 g/cm³
(0.0008 lbs/in³)can be measured.The instrument can also be
adapted to products with lower density >0.008 g/cm³
(0.0003 lbs/in³).

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.
The packaging of standard instruments consists of environ-
ment-friendly,recyclable cardboard.In addition,the sensor is
provided with a protective cover of cardboard.For special
versions PE foam or PE foil is also used.Dispose of the
packaging material via specialised recycling companies.
