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.

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.

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

Set the indication approximately to the middle of the LED indicating
board until the yellow relay control lamp changes condition.
Depending on the vessel size,process and/or medium,you have to
adjust the sensitivity of VEGAMIP 61 more or less sensitive.In
products with low signal damping,in small vessels or pipelines or with
buildup,it can be necessary to test the switching function.
By means of the LED indicating board,you can see the actual
receiving level during adjustment.
When the indication moves to the right,the instrument will be more
insensitive,to the left more sensitive.
In applications with products having a good signal damping (for
example stones,ore,sand,cement)and where buildup and
contamination is expected,you should adjust the instrument more
insensitive.In this case,the VEGAMIP 61 switches only with a
relatively high signal damping by the medium.Probable buildup does
not influence the measurement.

The switching delay can be adjusted in seven steps between 100 ms
and 20 s.

Fig.32:Adjust switching delay -LED indication flashes
If the indication moves to the right,the switching delay will be longer,to
the left shorter.
The indication returns automatically to the indication of the actual
receiving level after approximately 10 s.
If possible,you can simulate a filling between emitting and receiving
unit by using the hand or a metal sheet and check if the switching point
is adjusted correctly.If the relay control lamp changes the switching
condition,then the switching function is correct.

7Maintenance and fault rectification
7.1Maintenance
When the device is used correctly,no maintenance is required in
normal operation.
7.2Rectify malfunctions
The operator of the system is responsible for taking suitable measures
to remove interferences.
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.
Error Cause Removal
VEGAMIP 61 signals
"covered"when the vibra-
ting element is not sub-
merged (overfill protection)
or
VEGAMIP 61 signals
"uncovered"when the vib-
rating element is submer-
ged (dry run protection)
Operating voltage too low Check operating voltage
Buildup on the sensor Check if there is buildup on the two sensors,and if so,
remove it.
Wrong mode selected Set the correct mode on the mode switch (max.:
overflow protection,min.: dry run protection). Wiring
should be carried out according to the quiescent current
principle.
Unfavourable installation
location
Mount the sensor (emitter/receiver)in a position where
there is a lot of measured product between emitting and
receiving unit.
Electronics defective Press the mode switch.If the instrument then does not
change the mode,the electronics module is defective.
Exchange the electronics module.
Sensor defective Push the mode switch (min./max.). If the instrument
switches over,the sensor can be covered or mechani-
cally damaged.
Should the switching function on the correct mode be
wrong again,the you should return the instrument for
repair.
Signal lamp lights red Operating voltage too low Check operating voltage
Electronics module has
detected an internal failure
Exchange the instrument or send it in for repair
Instrument switches de-
layed
