3.2Principle of operation
VEGAFLEX 65 is a level sensor with pipe probe for continuous
level measurement.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
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.

The supply voltage range can differ depending on the
instrument version.
Data for power supply are specified in chapter "Technical
data".
The backlight of the indicating and adjustment module is
powered by the sensor.The prerequisite for this is a supply
voltage at a certain level.The exact voltage specifications are
stated in chapter "Technical data".
The optional heating requires its own power supply.You can
find further details in the supplementary instructions manual
"Heating for indicating and adjustment module".
This function is generally not available for approved instru-
ments.
3.3Operation
VEGAFLEX 65 can be adjusted with different adjustment
media:
lwith indicating and adjustment module
lwith the suitable VEGA DTM in conjunction with an
adjustment software according to the FDT/DTM standard,
e.g.PACTware and PC
lwith manufacturer-specific adjustment programs AMS™or
PDM
lWith a HART handheld
The entered parameters are generally saved in VEGAFLEX
65,optionally also in the indicating and adjustment module or
in PACTware.
3.4Packaging,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 environ-
ment-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 instruc-
tions can cause damage to the device.

4Mounting
4.1General 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 down-
ward 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.

31845-EN-080716

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.These min.
distances are listed in chapter "Technical data"in the
"Supplement".
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.
4.2Mounting instructions
Mount VEGAFLEX 65 in such a way that the probe does not
touch any installations or the vessel wall during installation.
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 vessel bottom.
Fig.3:Vessel with conical bottom
Make sure that the probe is not subjected to strong lateral
forces.Mount VEGAFLEX 65 at a position in the vessel where
no disturbances,e.g.from filling openings,agitators,etc., can
occur.

Fig.4:Lateral load
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 65 to vibrate in resonance.
Should a coax probe of more than 1m(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.

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 overvoltage surges are expected,overvoltage arresters
should be installed
Tip:
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.
Power supply and current signal are carried on the same two-
wire 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,VEGAS-
TAB 690 as well as all VEGAMETs meet this requirement.
Bear in mind the following factors regarding supply voltage:
lOutput voltage of the power supply unit can be lower under
nominal load (with a sensor current of 20.5mAor 22 mAin
case of fault message)
lInfluence of additional instruments in the circuit (see load
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.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 other diameter or cross-
section,you have to exchange the seal or use a suitable cable
gland.

VEGAFLEX 65 •4…20 mA/HART 15
5Connecting to power supply
31845-EN-080716

We generally recommend the use of screened cable for HART
multidrop mode.
On the instrument with cable entry ½NPT and plastic housing
there is a metallic ½" threaded insert moulded into the plastic
housing.
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.1nF,1500 V). The low frequency potential equalisation
currents are thus suppressed,but the protective effect against
high frequency interference signals remains.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equal-
isation 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.
5.2Connection steps -Instrument housing
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove
it by turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip
approx.1cm (0.4in)insulation from the ends of the
individual wires
5Insert the cable through the cable gland into the sensor
