2 For your safety
operating instructions manual may be carried
out only by personnel authorised by the manu-
facturer. Arbitrary conversions or modifications
are explicitly forbidden.
The safety approval markings and safety tips on
the device must also be observed.
Depending on the instrument version, the
emitting frequencies are in the C, K or W band
range. The low emitting frequencies are 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 guidelines. By affixing the CE
marking, we confirm the conformity of the instru-
ment with these guidelines.
You can find the EU conformity declaration on
our website under www.vega.com/downloads.
2.6
Radio license for Europe
The instrument was tested according to the
latest issues of the harmonized standards:
•
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.
In EFTA countries, the use is approved as far as
these standards were implemented.
For operation inside of closed vessels, the
following conditions must be fulfilled:
•
The instrument must be permanently
mounted on a closed vessel made of metal,
reinforced concrete, or comparable attenua-
ting materials
•
Flanges, process fittings and mounting
accessories must ensure the microwave
impermeability of the vessel and not let the
radar signal escape to the outside
•
If necessary, existing viewing windows in
the vessel must be coated with a microwave
impermeable material (e.g. electrically con-
ductive coating)
•
Manholes and flanges on the vessel must
be closed and sealed to avoid penetration of
the radar signal
•
The instrument should be preferably
mounted on top of the vessel with antenna
orientation downward
24
•
The instrument must only be installed and
maintained by appropriately qualified staff
For operation outside of closed vessels, the
following conditions must be fulfilled:
•
The installation must be carried out by
trained qualified personnel
•
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".

Regulations for the USA
The VEGAPULS WL S 61 must neither be ope-
rated in the USA nor imported or exported.
2.8
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.
