Overview
1 Overview
1.1 Application area
VEGAPULS 6X is a radar sensor for continuous level measurement of
liquids and bulk solids.
The small process fittings offer particular advantages for liquids in small
tanks or tight mounting spaces. The very good signal focusing ensures
the use in vessels with many installations such as stirrers and heating
spirals.
For bulk solids under most different process conditions, the device is ide-
al for level measurement in very high silos, large bunkers and segmented
vessels. The VEGAPULS 6X is equipped with different antenna systems.
1.2 Applications Fig. 2: Adjustment via PACTware or app
The VEGAPULS 6X can be used in almost all industrial areas and ap-
plications. It is selected and adapted simply by an application-orientated

• Exact measuring results independent of process conditions well as manufacturer-specific programs such as AMS™ or PDM.
1.4 Electronics versions
The device is available in different electronic versions.
In addition to 4 … 20 mA/HART in two and four-wire versions, digital
versions with Profibus PA, Ethernet APL and Modbus protocol are also
possible.
In addition, the VEGAPULS 6X can also be configured with integrated
overvoltage arrester or additional current output.
1.5 Adjustment
Adjustment directly at the measuring point
The adjustment of the instrument is carried out via the optional display
and adjustment module PLICSCOM or via a PC with the adjustment
software PACTware and corresponding DTM.
Wireless adjustment via Bluetooth
The Bluetooth version of display and adjustment module enables a wire-
less connection to standard adjustment units. This can be smartphones/
tablets with iOS or Android operating system or PCs with PACTware and
Bluetooth USB adapter.
Fig. 1: Wireless connection to standard operating devices
Adjustment is hence carried out via a free-of-charge app from the
Apple App Store or the Google Play Store or the adjustment software
PACTware and respective DTM.

The is provided with a balanced, shielded, twisted-pair cable with a char-
acteristic impedance in the range of 100 Ω ± 20 % in a frequency range 2
of 100 kHz to 20 MHz (measured acc. to [ASTM D4566-05] or equivalent 5
international standard). Wire diameters can be in the range of 26 AWG Link

Cable screening and grounding
A cable screening is always required, see APL Engineering Guideline.
You can find the guideline under www.ethernet-apl.org. 1( + ) 2 (-) 5 6 7 8
In systems with potential equalisation, connect the cable screening di-
rectly to ground potential at the power supply unit, in the connection box 1 4
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 Fig. 17: Connection compartment, double chamber housing
must be connected to the potential equalisation (low impedance). 1 Voltage supply, signal output

Configuration of the electronics
The plug-in electronics is mounted in the electronics compartment of the
instrument and can be exchanged by the user when servicing is required.
The electronics is completely encapsulated to protect against vibration
and moisture.
A plug with USB interface for parameter adjustment is located on top of
the electronics.
The supplementary electronics with connection terminals for connection
to the voltage supply and the Modbus are accommodated in the separate
connection compartment.
Voltage supply
Power supply via the Modbus host (RTU)
• Operating voltage
– 8 … 30 V DC
• max. number of sensors
– 32
Connection cable
The instrument is connected with standard two-wire, twisted cable suit-
able for RS 485. If electromagnetic interference is expected which is
above the test values of EN 61326 for industrial areas, shielded cable
should be used.
For power supply, a separate two-wire cable is required.
Make sure that the entire installation is carried out according to the Field-
bus specification. In particular, make sure that the bus is terminated with
suitable terminating resistors.
