3 Product description
3.2 Principle of operation
Application area
Functional principle
VEGAVIB 61 is a point level sensor with vibrating rod 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, VEGAVIB 61 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 VEGAVIB 61 was ordered for solid detection in water, the vibrating
rod is calibrated to the density of water. If covered by water (density:
1 g/cm³/0.036 lbs/in) VEGAVIB 61 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 module of VEGAVIB 61 monitors continuously the
following criteria:
l Correct vibrating frequency
l Line 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 output is open (safe
condition).
The vibrating rod is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 360 Hz. When the
vibrating rod 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
VEGAVIB 61 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, a
pump etc.).
The data for power supply are specified in chapter "Technical data".
3.3 Operation
With the factory setting, products with a density of > 0.05 g/cm³
(0.002 lbs/in³) can be measured. It is possible to adapt the instrument
for products with lower density > 0.02 g/cm³ (0.0007 lbs/in³).
On the electronics module you will find the following indicating and
adjustment elements:

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.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
l Storage and transport temperature see chapter "Supplement -

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, VEGAVIB 61 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.

Do not hold VEGAVIB 61 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.

Handling
Socket
Filling opening
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 screwing in.
4.2 Instructions for installation
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.
Mount the instrument in such a way that the vibrating rod does not
protrude directly into the filling stream.

Material cone
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 rod detects an average value of the material cone.
The vibrating rod 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.

Horizontal installation
To achieve a very precise switching point, you can install VEGAVIB 61
horizontally. However, if the switching point can have a tolerance of a
few centimeters, we recommend mounting VEGAVIB 61 approx. 20°
inclined to the vessel bottom to avoid buildup.

Baffle protection against
falling rocks
If VEGAVIB 61 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAVIB 61 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
In applications such as grit chambers or settling basins for coarse
sediments, the vibrating element must be protected against damage
with a suitable baffle.
This baffle must be manufactured by you.

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
VEGAVIB 61 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 VEGAVIB
61.
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
2 Loosen compression nut of the cable entry
3 Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires

6.1 General information
The figures in brackets refer to the following illustrations.
Function/Configuration
Electronics and connec-
tion compartment
On the electronics module you will find the following indicating and
adjustment elements:
l Potentiometer for adaptation to the product density (1)
l DIL switch for mode adjustment - min./max. (2)
l Signal lamp (5)
Note:
As a rule, always set the mode with mode switch (2) before starting the
setup of VEGAVIB 61. The switching output will change if you set the
mode switch (2) afterwards. This could possibly trigger other
connected instruments or devices.

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.

29267-EN-120418
6 Set up
As a default setting, the potentiometer of VEGAVIB 61 is set to the
complete right position (> 0.3 g/cm³/0.011 lbs/in³). In very light solids
you have to turn the potentiometer to the complete left position
(0.02 … 0.1 g/cm³ or 0.0007 … 0.0036 lbs/in³). By doing this,
VEGAVIB 61 will be more sensitive and light solids can be detected
more reliably.
For instruments detecting solids in water, these settings are not
applicable. The switching point adaptation is preset and must not be
changed.
Mode adjustment (2)
Signal lamp (5)
With the mode switch (min./max.) you can change the switching status
of the transistor output. You can set the required mode according to
the "Function chart" (max. - max. detection or overflow protection, min.
- min. detection or dry run protection).
We recommend connecting according to the quiescent current
principle (switching output is opened when the switching point is
reached) because the transistor output takes on the same (safe)
condition if a failure is detected.

Error Cause Rectification
Wrong mode selected Set the correct mode on the mode switch (overflow
Signal lamp flashes red Error on the vibrating ele-
ment
Interference on the electronics module
instrument defective Exchange the instrument or send it in for repair
protection, dry run protection). Wiring should be carried
out according to the quiescent current principle.
Check if the vibrating element is damage or extremely
corroded.
Exchanging the electronics module
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 VB60 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)

7 Maintenance and fault rectification
6 Pull out the old electronics module
7 Compare the new electronics module with the old one. The type
label of the electronics module must correspond to that of the old
electronics module. This applies particularly to instruments used in
hazardous areas.
8 Compare the settings of the two electronics modules. Set the
adjustment elements of the new electronics module to the same
setting of the old one.
Information:
Make sure that the housing is not rotated during the electronics
exchange. Otherwise the plug may be in a different position later.
9 Insert the electronics module carefully. Make sure that the plug is
in the correct position.
10 Screw in and tighten the two holding screws with a screwdriver
(Torx size T10 or P hillips 4)
11 Insert the wire ends into the open terminals according to the wiring
plan
12 Press down the opening levers of the terminals, you will hear the
terminal spring closing
13 Check the hold of the wires in the terminals by lightly pulling on
them
14 Check cable gland on tightness. The seal ring must completely
encircle the cable.
15 Screw the housing cover back on
The electronics exchange is now finished.
