4.1 General instructions
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°).
Before beginning the welding work, remove the oscillator
(electronics) 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.

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 min. distances (dead bands) are listed in
chapter "Technical data".
Pressure
Mounting position
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 66 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 possible. The exact value of the

Standpipes or bypass tubes are normally metal tubes with a
diameter 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.
The max. temperature is 250 °C (482 °F).
If VEGAFLEX 66 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.
The max. temperature for the spacers is 250 °C (482 °F).
A special high temperature version of VEGAFLEX 66 with
integrated bypass tube can be used in applications with
temperatures up to 400 °C (752 °F).

Excessive system vibration or shocks, e.g. caused by agitators
or turbulence in the vessel (e.g. from fluidisation) can cause
the coax probe of VEGAFLEX 66 to vibrate in resonance.
Should a coax probe of more than 1 m (3.281 in) length should
be used, you can provide a suitable support or guy directly
above the end of the probe to stabilise it.
If there is a danger of the probe touching the vessel wall during
operation due to product movements or agitators etc., the
measuring probe should be securely fixed.
In the gravity weight there is a thread (M12), e.g. for a ring bolt
(article no. 2.27424).
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.
VEGAFLEX 66 should be integrated in the vessel installation.
This prevents the electronics from strong heating by heat
radiation.

In
hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
Power supply and current signal are carried on the same twowire cable. The voltage supply range can differ depending on
the instrument version.
Data for power supply are specified in chapter "Technical
data".
Provide a reliable separation between the supply circuit and
the mains circuits according to DIN VDE 0106 part 101. The
VEGA power supply units VEGATRENN 149A Ex, VEGASTAB 690 as well as all VEGAMETs meet this requirement.
Bear in mind the following factors regarding supply voltage:
l Outpu

case of fault message)
l Influence

values 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 other diameter or crosssection, you have to exchange the seal or use a suitable cable
gland.

On the instrument with cable entry ½ NPT and plastic housing
there is a metallic ½" threaded insert moulded into the plastic

Caution:
No
grease should be used when screwing the NPT cable
gland or steel tube into the threaded insert. Standard grease
can contain additives that corrode the connection between
threaded insert and housing. This would influence the stability
of the connection and the tightness of the housing.
If screened cable is necessary, connect the cable screen on
both ends 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.

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.

6.4 Setup
procedure
After connecting VEGAFLEX 66 to power supply or after a
voltage recurrence, the instrument carries out a self-check for
approx. 30 seconds:
l Internal
l Indication of the instrument type, the firmware
check of the electronics
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 66 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.

Application
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" the selection "Liquid" or "Solid".
With coax versions, this menu item must be set to "Liquid".
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 adapted perfectly to the product
and measurement reliability, particularly in products with bad
reflective properties, is considerably increased.
Enter the requested parameter via the appropriate keys, save
your settings and jump to the next menu item with the [->] key.
Damping
To suppress fluctuations in the measured value display, e. g.
caused by an agitated product surface, an integration time 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. with a
cylindrical or spherical tank - and the indication or output of the
volume is required. Corresponding linearization curves are
preprogrammed for these vessels. They represent the
correlation between the level percentage and vessel volume.
By activating the appropriate curve, the volume percentage of
the vessel is displayed correctly. If the volume should not be
displayed in percent but e.g. in l or kg, a scaling can be also
set in the menu item "Display".

Caution:
Note
the following, if VEGAFLEX 66 is used as part of an
overfill protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no
longer compulsorily linear proportional to the level. This must
be taken into consideration by the user, particularly when
adjusting the switching point on the level switch.

Gatin
g out of false sig-
nals
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 empty vessel so that all potential interfering reflections will
be detected.
Probes in coax version require no gating out of false echoes
since they are not influenced by false reflections.

8.3 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the
user.
In Ex
applications only one oscillator with respective Ex
approval may be used.
If there is no electronics module available on site, one can be
ordered from the agency serving you.
The new oscillator must contain the order data of the sensor.
These can be loaded as follows:
the factory by VEGA
l At
l Or on site by the user
Information:
When
loading on site, first of all the order data must be
downloaded from the Internet (see operating instructions
manual "Oscillator").
In both cases, the serial number of VEGAFLEX 66 is required.
The serial numbers are stated on the type label of VEGAFLEX
66, on the inner wall of the housing or on the delivery note.
Assignment
The oscillators are adapted to the respective sensor and differ
in their signal output or in their power supply. You can find a
suitable oscillator in the following overview.
