1.1 Authorised personnel
All operations described in this documentation must be carried out
onlybytrained,qualiedpersonnelauthorisedbytheplantoperator.
During work on and with the device, the required personal protective
equipment must always be worn.
1.2 Appropriate use
VEGAPULS 68 is a sensor for continuous level measurement.
Youcannddetailedinformationabouttheareaofapplicationin
chapter " Product description".
Operational reliability is ensured only if the instrument is properly
usedaccordingtothespecicationsintheoperatinginstructions
manual as well as possible supplementary instructions.
1.3 Warning about incorrect use
Inappropriate or incorrect use of this product can give rise to applica-
tion-specichazards,e.g.vesseloverllthroughincorrectmounting
or adjustment. Damage to property and persons or environmental
contamination can result. Also, the protective characteristics of the
instrument can be impaired.
1.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and directives. The instrument must only be operated in a
technicallyawlessandreliablecondition.Theoperatorisresponsi-
ble for the trouble-free operation of the instrument. When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
The safety instructions in this operating instructions manual, the na-
tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may be
carried out only by personnel authorised by the manufacturer. Arbi-
traryconversionsormodicationsareexplicitlyforbidden.Forsafety
reasons,onlytheaccessoryspeciedbythemanufacturermustbe
used.
To avoid any danger, the safety approval markings and safety tips on
the device must also be observed.
The low transmitting power of the radar sensor is far below the inter-
nationallyapprovedlimits.Nohealthimpairmentsaretobeexpected
with intended use.The band range of the measuring frequency can
be found in chapter " Technical data".

4 Connecting to power supply
4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics.To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
4. Removeapprox.10cm(4in)ofthecablemantle,stripapprox.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

end sleeves, press the terminal from above with a small screwdriver,
the terminal opening is then free.When the screwdriver is released,
the terminal closes again.

The display and adjustment module can be inserted into the sensor
andremovedagainatanytime.Youcanchooseanyoneoffourdier-
ent positions - each displaced by 90°. It is not necessary to interrupt
the power supply.
Proceed as follows:
1. Unscrew the housing lid
2. Place the display and adjustment module on the electronics in the
desired position and turn it to the right until it snaps in.
3. Screw housing lid with inspection window tightly back on
Disassembly is carried out in reverse order.
The display and adjustment module is powered by the sensor, an ad-
ditional connection is not necessary.

The radar sensor as a distance measuring instrument measures the
distance from the sensor to the medium surface. For indication of the
real level, an allocation of the measured distance to the percentage
height must be carried out.

Forthisadjustment,thedistanceisenteredformin.andmax.level.
If these values are not known, an adjustment with distances, for
example,of10%and90%isalsopossible.Startingpointforthese

The function " Echo curve memory" makes it possible to save the
echo curve at the time of setup.This is generally recommended, and
it is absolutely necessary if you want to use the Asset Management
functions. If possible, the curve should be saved with a low level in the
vessel.
With the adjustment software PACTware and a PC, a high resolution
echocurvecanbedisplayedandusedtorecognizesignalchanges
during operation. In addition, the echo curve of setup can be dis-
played in the echo curve window and compared with the current echo
curve.
Thefollowingcircumstancescauseinterferingreectionsandcan
inuencethemeasurement:
• Highmountingnozzles
• Vessel internals such as struts

• Agitators
• Buildup or welded joints on vessel walls
Note:
A false signal suppression detects, marks and saves these false
signals to ensure that they are ignored in the level measurement.
This should be done with the lowest possible level so that all potential
interferingreectionscanbedetected.
Proceed as follows:
1. Select with [->] the menu item " False signal suppression" and
conrmwith[OK].
2. Conrm3-timeswith[OK] and enter the actual distance from the
sensor to the product surface.
3. All interfering signals in this range are detected by the sensor and
storedafterbeingconrmedwith[OK].
Note:
Check the distance to the medium surface, because if an incorrect
(toolarge)valueisentered,theexistinglevelwillbesavedasafalse
signal. The level would then no longer be detectable in this area.
If a false signal suppression has already been saved in the sensor,
the following menu window appears when selecting " False signal
suppression":
Delete: An already created false signal suppression will be com-
pletely deleted. This is useful if the saved false signal suppression no
longer matches the metrological conditions in the vessel.
Extend:isusedtoextendanalreadycreatedfalsesignalsuppres-
sion.This is useful if a false signal suppression was carried out with
too high a level and not all false signals could be detected. When
selecting " Extend", the distance to the medium surface of the created
false signal suppression is displayed.This value can now be changed
andthefalsesignalsuppressioncanbeextendedtothisrange.

The security concept of Bluetooth operation absolutely requires that
the default setting of the sensor PIN be changed.This prevents unau-
thorizedaccesstothesensor.
The default setting of the sensor PIN is " 0000". First of all you have
to change the sensor PIN in the adjustment menu of the sensor, e.g.
to " 1111":
1. In the adjustment menu, go to " Additional adjustments", " PIN"
Note:
The menu item " PIN" is only displayed if in the menu " Setup", " Lock/
Unlock adjustment" the adjustment is released.
2. Change sensor PIN

PIN is deactivated and when it is activated (adjustment menu "
Setup", " Lock/Unlock adjustment").
