3 Product description
Functional principle
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereflectedbytheproduct
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropriate output signal and outputted as measured value.

When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"Setup").
If you cannot maintain this distance, you should carry out a false
signal storage during setup. This applies particularly if buildup on the
vessel wall is expected. In such cases, we recommend repeating the
false signal storage at a later date with existing buildup.

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.

Vessel installations
The mounting location of the radar sensor should be a place where no
otherequipmentorfixturescrossthepathofthemicrowavesignals.
Vessel installations, such as e.g. ladders, limit switches, heating spirals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring point that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.

Safety instructions
Connecting to power supply
5.1
Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
•
•
Voltage supply via mains
voltage
The electrical connection must only be carried out by trained
personnel authorised by the plant operator.
If overvoltage surges are expected, overvoltage arresters should
be installed.
In this case, the 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 national installation regulations.
Supply voltage and current signal are carried on separate connection
cables if reliable separation is required. The supply voltage range can
differdependingontheinstrumentversion.
Thedataforpowersupplyarespecifiedinchapter"Technicaldata".
Voltage supply via low
voltage
In this case, the instrument is designed in protection class II. Generallyconnecttheinstrumenttovesselground(potentialequalization)
or with plastic vessels to the next ground potential. For this purpose, a
ground terminal is located laterally on the instrument housing.
Connection cable
An approved, three-wire installation cable with PE conductor is
required for voltage supply with mains voltage.
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 61326-1 for industrial areas,
screened cable should be used.
Use cable with round cross section for instruments with housing and
cablegland.Toensurethesealeffectofthecablegland(IPprotection
rating),findoutwhichcableouterdiameterthecableglandissuitable
for.
Useacableglandfittingthecablediameter.
Cable gland ½ NPT
With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.
36500-EN-140922
Max. torque for all housings see chapter "Technicaldata".
Cable screening and
grounding
If screened cable is required, we recommend connecting 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 ground potential (low impedance).
In Ex systems, the grounding is carried out according to the installation regulations.
VEGAPULS 61 • 4 … 20 mA/HART - four-wire

5 Connecting to power supply
In electroplating and CCP systems (cathodic corrosion protection) it
mustbetakenintoaccountthatsignificantpotentialdifferencesexist.
This can lead to unacceptably high currents in the cable screen if it is
grounded at both ends.
Information:
Themetallicpartsoftheinstrument(processfitting,transmitter,concentric tube, etc.) are conductively connected with the inner and outer
ground terminal on the housing. This connection exists either directly
via connecting metallic parts or, in case of instruments with external
electronics, via the screen of the special connection cable.
Youcanfindspecificationsonthepotentialconnectionsinsidethe
instrument in chapter "Technicaldata".
Cable screening and
grounding
If screened cable is required, we recommend connecting 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 ground potential (low impedance).
In Ex systems, the grounding is carried out according to the installation regulations.
Connection technology
5.2
Connection
The voltage supply and signal output are connected via the springloaded 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.
Connection procedure
Proceed as follows:
1. Unscrew the housing cover
2. Loosen compression nuts of the cable glands
3. Remove approx. 10 cm (4 in) of the cable mantle (signal 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

6. Check the hold of the wires in the terminals by lightly pulling on
them
7. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation in case of power
supply via low voltage
8. Connect the lead cable for power supply in the same way according to the wiring plan, in addition connect the ground conductor to
the inner ground terminal when powered with mains voltage.
9. Tighten the compression nut of the cable glands. The seal ring
must completely encircle the cables
10. Screw the housing cover back on

Setup - Adjustment
Since the radar sensor is a distance measuring instrument, the
distance from the sensor to the product surface is measured. For
indication of the real level, an allocation of the measured distance to
the percentage height must be carried out.

measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.
The "False signal suppression" displays the saved false echoes (see

Note:
Check the distance to the product 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 completely 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 suppression. This is useful if a false signal suppression was carried out with
a too high level and not all false signals could be detected. When
selecting "Extend", the distance to the product 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.
Additional adjustments Linearization curve
A linearisation is necessary for all vessels in which the vessel volume
doesnotincreaselinearlywiththelevel-e.g.inahorizontalcylindrical or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation 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".

Saving the parameter adjustment data
We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.
If the instrument is equipped with a display and adjustment module,
the data in the sensor can be saved in the display and adjustment
module. The procedure is described in the operating instructions
manual "Display and adjustment module" in the menu item "Copy
sensor data". The data remain there permanently even if the sensor
power supply fails.
The following data or settings for adjustment of the display and adjustment module are saved:
•

•
All data of the menu "Setup" and "Display"
In the menu "Additional adjustments" the items "Sensor-specific
units, temperature unit and linearization"

The function can also be used to transfer settings from one instrument to another instrument of the same type. If it is necessary to
exchange a sensor, the display and adjustment module is inserted
into the replacement instrument and the data are likewise written into
the sensor via the menu item "Copy sensor data".
