3.2 Principle of operation
VEGAFLEX 62 is a level sensor with cable or rod probe for continuous
level measurement.
It is designed for industrial use in all areas of process technology and
can be used equally well in liquids or solids.
High frequency microwave pulses are guided along a steel rope or a
rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and
outputted as distance.

4.1 General instructions
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" or on the
type label.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
In case of difficult installation conditions, the probe can be also
mounted laterally. For this purpose, adapt the rod with rod extensions
or bow-shaped segments.
The sensor must be readjusted to compensate the resulting running
time changes.

Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.
Use the hexagon for screwing in.
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.

Mounting position
Fig. 4: Measures
The reference plane for the measuring range of the sensors is the
sealing surface of the thread or flange.
Keep in mind that a min. distance must be maintained below the
reference plane and possibly also at the end of the probe measurement in these areas is not possible (dead band). Keep in mind
that the cable length cannot be used all the way to the end because
measurement in the area of the gravity weight is not possible. These
dead bands are listed in chapter "Technical data". Keep in mind for the
adjustment that the default setting for the measuring range refers to
water.
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 specified in chapter "Technical data"
or on the type label of the sensor.

4.2 Mounting instructions
Mount VEGAFLEX 62 in such a way that the distance to vessel
installations or to the vessel wall is at least 300 mm (12 in).
During operation, the probe must not touch any installations or the
vessel wall. If necessary, fasten the probe end.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the bottom. When using the cable version,

keep in mind that measurement down to the tip of the probe is not
ble. The exact value of the min. distance (lower dead band) is
possi
stated in chapter "Technical data".
Vessel type
Fig. 5: Vessel
with conical bottom
Plastic vessel/Glass vessel
The guided microwave principle requires a metal surface on the
process fitting. Therefore use in plastic vessels etc. an instrument
version with flange (from DN 50) or place a metal sheet (ø > 200 mm/
8 in) beneath the process fitting when screwing it in.
Make sure that the plate has direct contact with the process fitting.
In bypass tubes of plastic, a metal screen must be provided on the
outside. You can glue metal foil, for example, on the outside along the
entire length of the tube. This metal screen must be connected to the
ground terminal on the instrument.
When installing rod or cable probes without metal vessel wall, e.g. in
plastic vessels, the measured value can be influenced by strong
electromagnetic fields (emitted interference according to EN 61326:
class A).
In this case, use a probe in coax version.

this is not possible, use short sockets with small diameter.
Higher sockets or sockets with a bigger diameter can generally be

In such cases, always carry out a gating out of false signals after
installation. You can find further information under "Setup procedure".

Standpipes or bypass
tubes
pes or bypass tubes are normally metal tubes with a diameter
Standpi
of 30 … 200 mm (1.18 … 7.87 in). In measurement technology such a
tube corresponds to a coax probe. It does not matter if the standpipe is
perforated or slotted for better mixing. Lateral inlets with bypass tubes
also do not influence the measurement.
Measuring probes can be mounted in bypass tubes up to DN 200.
If VEGAFLEX 62 is used in standpipes or bypass tubes, contact with
the tube wall should be avoided. We offer spacers as accessories for
fastening the probe in the middle of the tube.
Depending on the tube diameter or tube length, one or several spacers
can be mounted. With cable probes, the cable can also be strained to
avoid contact with the tube.
Keep in mind that buildup can form on the spacers. Strong buildup can
influence the measurement.
Microwaves can penetrate plastics. For process technical reasons,
plastic standpipes are problematic. If durability is no problem, then we
recommend the use of metal standpipes.

Make sure that the probe cable is not completely taut. Avoid tensile
loads on the cable.
Avoid undefined cable-vessel connections, i.e. the connection must be
either grounded reliably or isolated reliably. Any deviation from this
requirement can lead to measurement errors.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
l If overvoltage surges are expected, overvoltage arresters should
be installed
Ti
p:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
In
hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the sensors
and power supply units.
Supply voltage and current output are carried on separate two-wire
connection cables if reliable separation is required. The supply voltage
range can differ depending on the instrument version.
The data for power supply are specified in chapter "Technical data".
The standard version can be operated with an earth-connected current
output, the Exd version must be operated with a floating output.
This instrument is designed in protection class I. 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.
Always connect the instrument to vessel ground (potential equalisation) or in case of plastic vessels to the next ground potential. For
this purpose there is a ground terminal on the side of the instrument
housing.
Connection cable
20 VEG
For power supply, an approved installation cable with PE conductor is
necessary.
The 4 … 20 mA current output 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.

screened cable is necessary, connect the cable screen on both ends
If
to ground potential. In the sensor, the screen must be connected
directly to the internal ground terminal. The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
If potential equalisation currents are expected, the connection on the
processing side must be made via a ceramic capacitor (e. g. 1 nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed, but the protective effect against high frequency interference signals remains.
Ta
ke note of the corresponding installation regulations for Ex
applications. In particular, make sure that no potential equalisation
currents flow over the cable screen. In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
With the Exd version, the minus side of the signal output is galvanically
connected to ground via protective diodes. When connecting the
instrument to a grounded PLC, equalising currents can flow in case of
potential differences which can cause malfunctions. Make sure that
there is sufficient potential equalisation from the system side or realise
the connection via switching amplifier.
5.2 Connection procedure
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 (current output),
strip approx. 1 cm (0.4 in) insulation from the ends of the individual
wires
4 Insert the cable into the sensor through the cable entry
5 Lift the opening levers of the terminals with a screwdriver
6 Insert the wire ends into the open terminals according to the wiring
plan
7 Press down the opening levers of the terminals, you will hear the
terminal spring closing
8 Check the hold of the wires in the terminals by lightly pulling on
them
9 Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation
10 Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
11 Connect the lead cable for power supply in the same way
according to the wiring plan, in addition connect the ground

6.4 Setup
steps
After connecting VEGAFLEX 62 to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds:
l Internal check of the electronics
l Indication of the instrument type, the firmware as well as the
sensor TAGs (sensor designation)
l Output signal jumps briefly (approx. 10 seconds) to the set fault
current
Then the corresponding current is outputted to the cable (the value
corresponds to the actual level as well as the settings already carried
out, e.g. factory setting).
In HART-Multidrop mode (several sensors on one input) the address
must be set before continuing with the parameter adjustment. You will
find a detailed description in the operating instructions manual
"Indicating and adjustment module" or in the online help of PACTware
or DTM.
HART mode
Standard
Address 0
As VEGAFLEX 62 is a distance measuring instrument, the distance
from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 % is
also possible. Starting point for these distance specifications is always
the seal surface of the thread or flange. With these settings, the real
level is calculated. Furthermore the operating range of the sensor is
limited from maximum to the required range.
The real product level during this adjustment is not important, because
the min./max. adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
In the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.
Caution:
there is a separation of different liquids in the vessel, e.g. by
If
condensation, VEGAFLEX 62 will always detect the medium with the
higher dielectric figure (ε

Application
Damping
Each product has different reflective properties. In addition, there are
various interfering factors which have to be taken into account:
agitated product surfaces and foam generation (with liquids); dust
generation, material cones and echoes from the vessel wall (with
solids). To adapt the sensor to these different conditions, you should
first select in this menu item under "Medium" either "Liquid" or "Solid".
Application
Liquid
Standard
(DK ≥ 2)
Depending on the dielectric figure (dielectri value or εr), measured
products can have a different reflective property. Therefore an
additional selection possibility is available.
Under "Sensitivity" you can select "Standard (DK ≥ 2)" or "Increased
sensitivity (DK < 2)".
Through this the sensor is optimally adapted to the product and
measurement reliability, particularly in products with bad reflective
properties, is considerably increased.
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.
To suppress fluctuations in the measured value display, e. g. caused
by an agitated product surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
the entire measurement will then be longer and the sensor will react to
measured value changes with a delay. In general, a period of a few
seconds is sufficient to smooth the measured value display.

Linearisation curve
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindrical
or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed for

Gating out of false signals
31838-EN-100426
VEGAFLEX 62 • 4 … 20 mA/HAR
High sockets or vessel installations, such as e. g. struts or agitators as
well as buildup and weld joints on the vessel walls, cause interfering
reflections which can impair the measurement. A false echo storage
detects and marks these false echoes, so that they are no longer taken
into account for the level measurement. A false echo memory should
be created with low level so that all potential interfering reflections can
be detected.

When used as directed in normal operation, VEGAFLEX 62 is
completely maintenance free.
8.2 Rectify malfunctions
The operator of the system is responsible for taking suitable measures
to remove interferences.
VEGAFLEX 62 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
The first measures to be taken are to check the output signals as well
as to evaluate the error messages via the indicating and adjustment
module. The procedure is described below. Further comprehensive
diagnostics can be carried out on a PC with the software PACTware
and the suitable DTM. In many cases, the causes can be determined
this way and faults rectified.
However, should these measures not be successful, call the VEGA
service hotline in urgent cases 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

Prepare update
Connect the sensor to power supply and provide connection from PC
to the instrument via VEGACONNECT. Start PACTware and provide
connection to the sensor, e.g. via the VEGA project assistant. Close
the parameter window of the sensor, as far as open.
Load software into sensor
Go in the PACTware menu bar to "Instrument data", "Additional
functions" and "Update instrument software".
PACTware now checks the actual hardware and software version of

Sensor parameter adjustment Gating out of false signals carried out
In bulk solids applications, implementing a false
signal suppression is generally not recommended.
The accuracy of bulk solid applications depends
considerably on the application. Hard and fast
accuracy specifications are thus not available.
Deviation see diagrams
Depending on the installation conditions, there can
be deviations which can be rectified with an
adaptation of the adjustment or a change of the
measured value offset in the DTM service mode.
