Product description
32251-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 62 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 62 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 62 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 62 continuously monitors the
following criteria:
lCorrect vibrating frequency
lLine break to the piezo drive
If one of the stated malfunctions 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.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 62 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
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).
On the electronics module you will find the following indicating
and adjustment elements:
lsignal lamp for indication of the switching condition (green/
red)
lpotentiometer for adaptation to the product density
lMode switch for selecting the switching condition (min./
max.)
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.

4Mounting
4.1General instructions
In general,VEGAWAVE 62 must be mounted vertically.The
instrument must be mounted in such a way that the vibrating
element is at the height of the requested switching point.
Use the recommended cable (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGAWAVE 62 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
Do not hold VEGAWAVE 62 on the vibrating element.
Especially with flange and tube versions,the sensor can be
damaged by the weight of the instrument.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low
pressure in the vessel.Before use,check if the seal material is
resistant against the measured product and the process
temperature.
The max.permissible pressure is stated in chapter "Technical
data"in the "Supplement"or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must
be treated accordingly.Bending the vibrating element will
destroy the instrument.

Mounting
32251-EN-070117

Warning:
The housing must not be used to screw the instrument in!
Applying tightening force on the housing can damage its
rotational mechanical parts.
To screw in,use the hexagon above the thread.
4.2Mounting instructions
Make sure that the max.permissible tensile load of the
suspension cable is not exceeded.The danger of this
happening exists particularly with very heavy solids and large
meas.lengths.The max.permissible load is stated under
"Technical data"in the "Supplement".
In silos with bulk solids,material cones can form which change
the switching point.Please keep this in mind when installing
the sensor in the vessel.We recommend selecting an
installation location where the sensor detects the average
value of the material cone.
The measuring probe must be mounted in a way that takes the
arrangement of the filling and emptying apertures into account.
To compensate measurement errors in cylindrical vessels
caused by the material cone,the sensor must be mounted at a
distance of d/6from the vessel wall.

3Filling opening
The vibrating element should protrude into the vessel to avoid
buildup.For that reason,avoid using mounting bosses for
flanges and screwed fittings.This applies particularly to use
with adhesive products.
IfVEGAWAVE 62 is mounted in the filling stream,unwanted
false measurements may be generated.Mount VEGAWAVE
62 at a location in the vessel where no disturbing influence
from e.g.filling openings,agitators,etc.can occur.

5Connecting to voltage supply
5.1Preparing the connection
Generally note the following safety instructions:
lConnect only in the complete absence of line voltage
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the
sensors and power supply units.
Connect the power supply according to the following diagrams.
Oscillator with contactless electronic switch is designed in
protection class 1.To maintain this protection class,it is
absolutely necessary that the ground conductor be connected
to the internal ground terminal.Take note of the general
installation regulations.As a rule,connect VEGAWAVE 62 to
vessel ground (PA), or in case of plastic vessels,to the next
ground potential.On the side of the housing there is a ground
terminal between the cable entries.This connection serves to
drain offelectrostatic charges.InEx applications,the
installation regulations for hazardous areas must be given
priority.
The data for power supply are stated in chapter "Technical
data"in the "Supplement".
VEGAWAVE 62 is connected with standard cable with round
cross-section.An outer cable diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable entry.
If cable with a different diameter or wire cross section is used,
exchange the seal or use an appropriate cable connection.
In hazardous areas,only use approved cable connections for
VEGAWAVE 62.
Take note of the corresponding installation regulations for Ex
applications.
5.2Connection procedure
With Ex instruments,the housing cover may only be opened if
there is no explosive atmosphere present.
To mount,proceed as follows:

We recommend connecting VEGAWAVE 62 in such a way that
the switching circuit is open when there is a level signal,line
break or failure (safe condition).
The contactless electronic switch is always shown in non-
operative condition.
The instrument is used for direct control of relays,contactors,
magnet valves,warning lights,horns etc.It must not be
operated without an intermediately connected load,because

the electronics would be destroyed if connected directly to the
mains.It is not suitable for connection to low voltage PLC
inputs.
Domestic current is temporarily lowered below 1mAafter
switching offthe load so that contactors,whose holding current
is lower than the constant domestic current of the electronics,
are reliably switched off.
