3.2 Principle of operation
Application area
Functional principle
VEGAWAVE 63 is a point level sensor with tuning fork for level
detection.
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 also works when subjected to strong external vibrations or changing
products.
Solid detection in water
If VEGAWAVE 63 was ordered for solids detection in water, the tuning
fork is set to the density of water. In air or when immersed in water
(density: 1 g/cm³/0.036 lbs/in), VEGAWAVE 63 signals "uncovered".
Only when the vibrating element is also covered with solids (e.g. sand,
sludge, gravel etc.) will the sensor signal "covered".
Fault monitoring
The electronics module of VEGAWAVE 63 monitors continuously the
following criteria:
l Correct vibrating frequency
l Line break to the piezo drive
If one of these faults is detected, the electronics signals this via a
defined 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 electronics module and
converted into a switching command.
Voltage supply
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 specified in chapter "Technical data".

3.3 Operation
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:
l Signal lamp for indication of the switching condition (yellow)
l Potentiometer for adaptation to the product density
l Mode switch to select the switching condition (reverse character-
istics)
l Simulation key
3.4 Storage and transport
Packaging
Transport
Transport inspection
Storage
Storage and transport
temperature
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 environmentfriendly, 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.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.

4.1 General instructions
Suitability for the process conditions
Switching point
Moisture
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
In general, VEGAWAVE 63 can be installed in any position. The
instrument only has to be mounted in such a way that the vibrating
element is at the height of the desired switching point.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument 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 outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

Transport
Pressure/Vacuum
10 VEGAWAVE 63 • - NAMUR
Do not hold VEGAWAVE 63 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.
32259-EN-120418

4 Mounting
The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
Handling
Agitators and fluidiza-
tion
Inflowing medium
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for scr ewing in.
4.2 Instructions for installation
Due to the effects of agitators, equipment vibration or similar, the level
switch can be subjected to strong lateral forces. For this reason, do not
use an overly long extension tube for VEGAWAVE 63, but check if you
can mount a short level switch on the side of the vessel in horizontal
position.
Extreme vibration caused by the process or the equipment, e.g.
agitators or turbulence in the vessel, e.g. by fluidisation, can cause the
extension tube of VEGAWAVE 63 to vibrate in resonance. This leads
to increased stress on the upper weld joint. Should a longer tube
version be necessary, you can provide a suitable support directly
above the vibrating element to secure the extension tube.
This measure applies mainly to applications in Ex areas. Make sure that
the tube is not subject to bending stress due to this measure.
If VEGAWAVE 63 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAWAVE 63 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
This applies particularly to instrument types with long extension tube.

Fig. 3: Inflowing medium
Lock fitting
Socket
Material cone
VEGAWAVE 63 can be mounted with a lock fitting for height
adjustment. Take note of the pressure information of the lock fitting.
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.
In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor in
the vessel. We recommend selecting an installation location where the
vibrating fork detects an average value of the material cone.
The tuning fork must be mounted in a way that takes the arrangement
of the filling and emptying apertures into account.
To compensate measurement errors caused by the material cone in
cylindrical vessels, the sensor must be mounted at a distance of d/6
from the vessel wall.

5.1 Preparing the connection
Note safety instructions
Take note of the
safety instructions for Ex
applications
Voltage supply
Connection cable
Connection cab-
le for Ex applications
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
Connect the operating voltage according to the following diagrams.
Take note of the general installation regulations. As a rule, connect
VEGAWAVE 63 to vessel ground (PA), or in case of plastic vessels, to
the next ground potential. On the side of the instrument housing there
is a ground terminal between the cable entries. This connection serves
to drain off electrostatic charges. In Ex applications, the installation
regulations for hazardous areas must be given priority.
The data for power supply are specified in chapter "Technical data".
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas, screened cable should be
used.
Use cable with round cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland. If you are
using cable with a different diameter or cross-section, exchange the
seal or use a suitable cable gland.
In hazardous areas, only use approved cable connections for
VEGAWAVE 63.
Take note of the corresponding installation regulations for Ex
applications.
Cover all housing openings conforming to standard according to
EN 60079-1.
5.2 Connection procedure
With Ex instruments, the housing cover may only be opened if there is
no explosive atmosphere present.
Proceed as follows:
1 Unscrew the housing cover

Switching point adaptation (1)
With the potentiometer you can adapt the switching point to the solid. It
is already preset and must only be modified in special cases.
20 VEGAWAVE 63 • - NAMUR
32259-EN-120418
Page 21
6 Set up
By default, the potentiometer of VEGAWAVE 63 is set to the right stop
(> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids, turn
the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/in³).
VEGAWAVE 63 will thus be more sensitive and can detect light-weight
solids more reliably.
For instruments detecting solids in water, these settings are not
applicable. The switching point adaptation is preset and must not be
changed.
Characteristics reversal
(2)
Simulation key (3)
Signal lamp (6)
The characteristics reversal can be carried out with the DIL switch.
You can choose between falling characteristic curve (switch position
max.) and rising characteristic curve (switch position min.). This allows
you to output the desired current.
Modes
l min. - rising characteristic curve (High current when immersed)
l max. - falling characteristics (Low current when immersed)
The NAMUR output can be switched over to falling or rising
characteristics (see also "Function chart").
The simulation key is located in a recess on the upper side of the
electronics module. Push the simulation key with a suitable object
(screwdriver, pen, etc.).
When the key is pushed, a line break between sensor and processing
unit is simulated. The signal lamp on the sensor extinguishes. The
measuring system must signal a fault and take on a safe condition
when the key is pushed.
Keep in mind that downstream connected instruments will be activated
during operation. This allows you to check the correct function of the
measuring system.

6 Set up
You can carry out the function test with the outputted current values
also directly via a safety PLC or a process control system.
Simulation key on the
electronics module
A function test can be carried out for measurement setups in
conjunction with the NAMUR electronics module WE60N. For this
purpose, the switching delay must be set to 0.5 s. VEGAWAVE 63 has
an integrated simulation key. The simulation key is lowered on the
electronics module. Push the simulation key for > 2 seconds.
If VEGAWAVE 63 is connected to an SPLC, you have to interrupt the
connection cable to the sensor for > 2 seconds.
After releasing the simulation key or briefly interrupting the connection
cable to the sensor, you can check the complete measuring system on
correct function. A switching procedure is simulated during the test.
Fig. 23: Flow chart of the function test
1 Full signal
2 Empty signal
Check if all the switching conditions occur in the correct sequence and
the stated time period. If this is not the case, there is a fault in the
measuring system. Keep in mind that connected instruments are
activated during the function test. This allows you to check the correct
function of the measuring system.
Note:
Keep in mind that the starting time t
of the voltage supply can extend
A
the time up to the first switching.
Test procedure
After releasing the button or after a brief line break.
The speci fied times apply with a tolerance of ±20 %.

7 Maintenance and fault rectification
7.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
7.2 Remove interferences
Reaction when malfunc-
tions occur
Failure reasons
The operator of the system is responsible for taking suitable measures
to rectify faults.
VEGAWAVE 63 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
l Sensor
l Process
l Voltage supply
l Signal processing
Fault rectification
The first measure to be taken is to check the output signal. In many
cases, the causes can be determined this way and the faults rectified.
24 hour service hotline
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.

Should the switching function in the correct mode still
be faulty, return the instrument for repair.
Push the characteristic reversal switch. If the instrument
then does not change the mode, the electronics module
may be defective. Exchange the electronics module.
Mount the instrument at a location in the vessel where
no dead zones or air bubbles can form.
Check the vibrating element and the sensor if there is
buildup and remove it.

Reaction after fault rectification
Depending on the reason for the fault and the measures taken, the
steps described in chapter "Set up" may have to be carried out again.
7.3 Exchanging the electronics module
In general, all electronics modules of series WE60 can be inter-
changed. If you want to use an electronics module with a different
signal output, you can download the corresponding operating
instructions manual from our homepage under Downloads.
With EEx d instruments, the housing cover may only be opened if there
is no explosive atmosphere present.
Proceed as follows:
1 Switch off power supply
2 Unscrew the housing cover
3 Lift the opening levers of the terminals with a screwdriver
4 Pull the connection cables out of the terminals
5 Loosen the two screws with a screw driver (Torx size T10 or slot 4)
