2 For your safety
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 manu-
facturer. Arbitrary conversions or modifications
are explicitly forbidden. For safety reasons, only
the accessory specified by the manufacturer
must be used.
To avoid any danger, the safety approval mar-
kings and safety tips on the device must also be
observed and their meaning looked up in this
operating instructions manual.
Depending on the instrument version, the
emitting frequencies are in the C, K or W band
range. The low emission power is far below the
internationally approved limit values. When used
correctly, the device poses no danger to health.
2.5
EU conformity
The device fulfils the legal requirements of the
applicable EU directives. By affixing the CE
marking, we confirm the conformity of the instru-
ment with these directives.
You can find the EU conformity declaration on
our website under www.vega.com/downloads.

Radio licenses for Europe
VEGAPULS WL S 61
The instrument was tested according to the
latest issue of the following harmonized stan-
dards:
•
EN 302372 - Tank Level Probing Radar
•
EN 302729 - Level Probing Radar
It is hence approved for use inside and outside
closed vessels in countries of the EU.
Use is also approved in EFTA countries,
provided the respective standards have been
implemented.
For operation inside of closed vessels, points a
to f in annex E of EN 302372 must be fulfilled.
For operation outside of closed vessels, the
following conditions must be fulfilled:
•
The installation must be carried out by
trained qualified personnel
24
•
The instrument must be stationary moun-
ted and the antenna directed vertically
downward
•
The mounting location must be at least 4 km
away from radio astronomy stations, unless
special permission was granted by the res-
ponsible national approval authority
•
When installed within 4 to 40 km of a radio
astronomy station, the instrument must not
be mounted higher than 15 m above the
ground.
You can find a list of the respective radio astro-
nomy stations in chapter "Supplement".
Bluetooth radio module
The radio module used in the instrument for wi-
reless Bluetooth communication was tested by
the manufacturer according to the latest edition
of the following standard:
•
EN 300328 – Wideband transmission
systems
It is hence for use inside closed vessels in coun-
tries of the EU and EFTA.
2.7
Security concept, Bluetooth
operation
Sensor adjustment via Bluetooth is based on a
multi-stage security concept.
Authentication
When starting Bluetooth communication, an au-
thentication is carried out between sensor and
adjustment device by means of the sensor PIN.
The sensor PIN is part of the respective sensor
and must be entered in the adjustment device
(smartphone/tablet). To increase adjustment
convenience, this PIN is stored in the adjust-
ment device. This process is secured via an
algorithm acc. to standard SHA 256.
Protection against incorrect entries
In case of multiple incorrect PIN entries in the
adjustment device, further entries are possible
only after a certain amount of time has passed.
Encrypted Bluetooth communication
The sensor PIN as well as the sensor data
are transmitted encrypted between sensor
and adjustment device according to Bluetooth
standard 4.0.
