3.2Principle of operation
VEGAMIP 61 is a microwave barrier for level detection.
It is designed for industrial use in all areas of process technology and
can be used in bulk solids and liquids.
Typical applications are overfill and dry run protection.With an
operating distance of 100 m,VEGAMIP 61 can be used,for example,
in bulk solids silos with large diameters.Thanks to its simple and
rugged measuring system,VEGAMIP 61 is virtually unaffected by the
process and the chemical and physical properties of the medium.
VEGAMIP 61 can be also used for detection of vehicles and ships or
for material recognition on conveyor belts.

4VEGAMIP 61 with angled antenna extension
The emitting unit transmits a focused microwave signal via horn
antenna to the receiving unit on the opposite side.If there is medium
between emitting and receiving unit,the signal is damped.This
change is detected by the built-in electronics module and converted
into a switching command.
3.3Packaging,transport and storage
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 environment-
friendly,recyclable 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.

With high process temperatures exceeding 80 °C,you have to use a
mounting adapter for the emitting and receiving unit.The mounting
adapter can be only used with the encapsulated horn antenna with
PTFE cover.

4Mounting
4.1General instructions
With instruments with threaded process fitting,suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in!Applying
tightening force can damage internal parts of the housing.
Make sure that all parts of the instrument exposed to the process,in
particular the antenna,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"or on the
type label.
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.
4.2Mounting instructions
If possible,install VEGAMIP 61 in a position where a high signal
damping by the medium is expected.

Avoid mounting the instrument too close to the vessel wall.Reflections
from the vessel wall or from vessel installation can influence the
switching accuracy.
Fig.4:Installation position (top view)
IfVEGAMIP 61 is mounted in the filling stream,unwanted false
measurement signals can be generated.For this reason,mount
VEGAMIP 61 at a position in the vessel where no disturbances,e.g.
from filling openings,agitators,etc., can occur.
Microwaves can penetrate non-conductive materials.Hence,it is
possible to measure through the wall of non-conductive vessels.
Fig.5:Bulk solids vessel of plastic
In metal vessels,you have to mount VEGAMIP 61 on flanges or
threaded sockets.It is also possible to measure through a window.In
general,all products such as glass,ceramic and plastic are suitable as
window material.

In general,the same as for metal vessels applies to concrete vessels
due to the steel braining.
In general,the same as for metal vessels applies to wood vessels due
to the liquid absorption of the wood.
VEGAMIP 61 can be used for detection of products in pipelines.In
pipelines of non-metallic products such as plastic or glass,the
measured product can be detected through the pipe wall.

Note:
In the case of VEGAMIP 61 with NPT thread,the instrument seals in
the thread itself.Hence,no counter nut is necessary for these
versions.
Avoid long sockets in which the medium can remain and if possible,
mount VEGAMIP 61 front-flush.This applies mainly if buildup and dust
are expected.

2Correct front flush installation
In very abrasive products,VEGAMIP 61 should be installed with a
mounting adapter or in front of a suitable window.In this case,you
have to use a window material which is appropriately resistant.
For an optimum switching signal,the two sensors must be adapted to
each other.The accuracy must be in a range of ±5°.
General rule:the bigger the antenna and the better it focusses,the
more precise the orientation has to be.

The emitting unit emits electromagnetic waves.The polarisation plane
is the direction of the electrical wave component.Its position is marked
on the instrument hexagon by polarisation markings.
For a reliable function,the emitting and receiving unit must be installed
in the same polarisation direction.
If several instrument pairs are installed in a vessel,the instrument pairs
can be coded by different polarisation positions to avoid that they
influence one another.

In tight mounting spaces or spaces subject to high temperatures,the
signal of VEGAMIP 61 can be guided via a deflector.You can use a
metal plate for this or an angled antenna extension on the side of the
emitting unit.In products with low dielectric value,we recommend
using an instrument version with antenna extension because it
focusses the signal optimally and has no signal loss.With instrument
versions with detachable horn antenna,the antenna extension can be
retrofitted.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltages are expected,install overvoltage arresters
Connect the operating voltage according to the following diagrams.
The oscillator with relay output 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
VEGAMIP 61 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 off
electrostatic charges.InEx 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.Acable outer diameter of 5…9mm
(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.
5.2Connection procedure
The connection of the voltage supply and the signal output is carried
out via the spring-loaded terminals in the housing.
Proceed as follows:
1Unscrew the housing cover
2Loosen compression nut of the cable entry
3Remove approx.10 cm (4in)of the cable mantle,strip approx.
1cm (0.4in)of insulation from the ends of the individual wires

Information:
Solid cores as well as flexible (stranded)cores with wire end sleeves
are inserted directly into the terminal openings.If you are using flexible
cores without end sleeves,press with a small screwdriver on the
terminal,the terminal opening is freed.When the screwdriver is
released,the terminal closes again.
6Check the hold of the wires in the terminals by lightly pulling on
them
7Connect the screen to the internal ground terminal,connect the
outer ground terminal to potential equalisation
8Tighten the compression nut of the cable entry.The seal ring must
completely encircle the cable
9Screw the housing cover on
The electrical connection is finished.
Information:
The terminal block is pluggable and can be removed from the
electronics.For this purpose,lift the terminal block with a small
screwdriver and pull it out.When inserting the terminal block again,
you should hear it snap in.
