3.2 Principle of operation
The radar sensor VEGAPULS WL 61 is the ideal sensor for all appli-
cations in the water and waste water industry. It is particularly suitable
for level measurement in water treatment, in pump stations as well as
stormwateroverowtanks,forowmeasurementinopenumesand
for gauge measurement.
The antenna of the radar sensor emits short radar pulses with a
durationofapprox.1ns.Thesepulsesarereectedbytheproduct
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 appropri-
ate output signal and outputted as measured value.
3.3 Packaging, 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 environment-
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 instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration

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 keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo stor-
age later with existing buildup.

Fig. 10: Mounting of the radar sensor on round vessel tops
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.

The mounting location of the radar sensor should be a place where no

Vessel installations, such as e.g. ladders, limit switches, heating spi-
rals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring site 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.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed
Power supply and current signal are carried on the same two-wire
cable.Thevoltagesupplyrangecandierdependingontheinstru-
ment version.
Thedataforpowersupplyarespeciedinchapter"Technicaldata".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN VDE 0106 part 101.
Keepinmindthefollowingadditionalfactorsthatinuencetheoperat-
ing voltage:
• Output voltage of the power supply unit can be lower under nomi-
nal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
• Inuenceofadditionalinstrumentsinthecircuit(seeloadvaluesin
chapter "Technicaldata")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
For instruments with housing and cable gland, use cable with round
cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)
ensuresthesealeectofthecablegland.Ifyouareusingcablewith

7.2 Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the con-
gurationsoftwarePACTwareandasuitableinstrumentdriver(DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec-
tion. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functionsareincludedinolderrmwareversions.Youcandownload
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manu-
al "DTMCollection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descrip-
tions are available in the online help of PACTware and the DTMs.

Since a 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 percent-
age height must be carried out. To perform the adjustment, enter the
distance with full and empty vessel, see the following example:

ing the product level. These settings can be made ahead of time
without the instrument having to be installed.
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for

9 Diagnosis, Asset Management and service
9.1 Maintenance
If the device is used correctly, no maintenance is required in normal
operation.
9.2 Measured value and event memory
The instrument has several memories which are available for diagno-
sis purposes. The data remain even with voltage interruption.
Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:
• Distance
• Filling height
• Percentage value
• Lin. percent
• Scaled
• Current value
• Meas. reliability
• Electronics temperature
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
• Modicationofaparameter
• Switchingonandotimes
• Status messages (according to NE 107)
• Error messages (according to NE 107)
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measure-
ment conditions during operation or buildup on the sensor can thus

Failure: Due to a malfunction in the instrument, a failure message is
outputted.
This status message is always active. It cannot be deactivated by the
user.
Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Outofspecication: The measured value is unstable because the
instrumentspecicationisexceeded(e.g.electronicstemperature).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Maintenance:Duetoexternalinuences,theinstrumentfunction
