Application area
3.2
Principle of operation
The instrument is suitable for applications with liquids in storage tanks
andprocessvesselsunderdifficultprocessconditions.Application
possibilities can be found in the chemical industry, in environmental
and recycling technology as well as in the petrochemical industry.
The version with standpipe antenna is particularly suitable for
measurement of solvents and liquid gases, for vessels with foam
generation or for measurement of products with low dielectric values
(DK > 1.6).
Measurement in a standpipe is not recommended for extremely
adhesive products.
The standard electronics enables the use of instruments in products
withanεr-Wert≥1.8.Theelectronicsversionwithincreasedsensitivity
enables the use of the instrument also in applications with very poor
reflectivepropertiesorproductswithanεrvalue≥1.5.Thevaluesthat
can be actually reached depend on the measurement conditions, the
antenna system or the standpipe or bypass tube.
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.
Packaging
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
3.3
Packaging, transport and storage
The packaging of standard instruments consists of environmentfriendly, 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 in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
Transport inspection
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with.
Storage
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:

Safety instructions
Connecting to power supply and bus
system
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
Voltage supply
The instrument requires an operating voltage of 8 … 30 V DC. Operating voltage and digital bus signal are carried on separate two-wire
connection cables.
Connection cable
The instrument is connected with standard two-wire, twisted cable
suitable for RS 485. 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…9mm(0.2…0.35in)ensuresthesealeffectofthecablegland.
Ifyouareusingcablewithadifferentdiameterorcross-section,
exchange the seal or use a suitable cable gland.
Make sure that the entire installation is carried out according to the
Fieldbusspecification.Inparticular,makesurethatthebusisterminated with suitable terminating resistors.
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.
Max. torque for all housings see chapter "Technicaldata".
41363-EN-140210
Cable screening and
grounding
In systems with potential equalisation, connect the cable screen
directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).
In systems without potential equalisation, connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor, the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen. The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The
low frequency potential equalisation currents are thus suppressed,
buttheprotectiveeffectagainsthighfrequencyinterferencesignals
remains.

Wherever the sensor displays a constant value, the reason could
also be the fault setting of the current output to "Hold value"
In case of a too low level indication, the reason could be a line
resistance that is too high

10.2 Basics Modbus
Bus description
The Modbus protocol is a communication protocol for the communication between instruments. It is
based on a Master/Slave or Client/Server architecture. By means of Modbus, a Master and several
Slaves can be connected. Each bus participant has an unambiguous address and can send messages to the bus. This is initiated by the Master, the addessed Slave answers. For data transfer, the
versions serial (EIA-485) as well as the mode RTU are available. In the RTU and ASCII mode interesting here, data will be transmitted in binary form. The telegram consists generally of the address,
the function, the data as well as the transmission check.
Bus architecture
In the version Modbus RTU, up to 32 participants can be connected to the bus. The length of the
twisted two-wire cable can be up to 1200 m. The bus must be terminated on both sides at the last
bus participant with a terminating resistor of 120 Ohm. The resistor is already integrated in the
VEGAPULS 62 and is activated/deactivated via a slide switch.

The Levelmaster commands are based on the following syntax:
•
•
•
•
•
•
Capitallettersareatthebeginningofcertaindatafields
Smalllettersstandfordatafields
All commands are terminated with "<cr>" (carriage return)
All commands start with "Uuu", whereby "uu" stands for the address (00-31)
"*" can be used as a joker for any position in the address. The sensor always converts this in
its address. In case of more than one sensor, the joker must not be used, because otherwise
several slaves will answer
Commands that modify the instrument return the command with "OK“. "EE-ERROR" replaces
"OK"iftherewasaproblemchangingtheconfiguration
