3.2 Principle of operation
VEGASWING 51 vibrating level switches detect lev-
els in almost all liquids.
• viscosity 0.1 … 10.000 mPa s
• density 0.7 … 2.5 g/cm³.
The tuning fork is piezoelectrically energised and
vibrates at its mechanical resonance frequency of
approx. 1200 Hz. When the tuning fork is submerged
in the product, the frequency changes. This change
is detected by the integrated oscillator and con-
verted into a switching command.
The integrated fault monitoring detects the following
faults (red LED flashes):
• interruption of the connection cable to the piezo-
electric elements
• extreme material wear on the tuning fork
• break of the tuning fork
• absence of vibration.
3.3 Storage and transport
Your instrument was protected by packaging during
transport. Its capacity to handle normal loads during
transport is assured by a test acc. to DIN 55439.
The packaging consists of carton. It is environment-
friendly and recyclable. Dispose of the packing ma-
terial via specialised recycling companies.
Material
• Packaging of cardboard.
• Storage and transport temperature -40 … +80°C
• Relative humidity 20 … 85 %.

Mounting
4 Mounting
4.1 Mounting instructions
In principle, VEGASWING 51 can be mounted in any
position. The instrument must be mounted such that
the tuning fork is at the height of the required switch-
ing point.
Do not hold VEGASWING 51 on the tuning fork.
The tuning fork is provided with lateral notches,
marking the switching point for vertical installation.
The reference medium for the switching point is wa-
ter. Make sure when mounting VEGASWING 51 that
this notch is at the height of the requested level.
Note that the switching point of the instrument shifts
when the medium has a density other than that of
water (water= 1.0 g/cm³).

In case of horizontal mounting in adhesive and vis-
cous products, the surfaces of the tuning fork should
be vertical in order to reduce buildup on the tuning
fork. The orientation of the tuning fork is marked by a
notch on the hexagon of VEGASWING 51. With this
you can check the position of the tuning fork when
screwing it in. When the hexagon touches the seal,
the thread can still be turned by approx. half a turn.
This is sufficient to reach the recommended mounting
orientation.
In case of adhesive and viscous products, the tuning
fork should protrude into the vessel/pipeline to avoid
buildup. Sockets for flanges and mounting bosses
should therefore not exceed a certain length.

Lateral load
Mounting
Make sure that the tuning fork is not subjected to
strong lateral forces. To assure this, mount
VEGASWING 51 at a location in the vessel where no
adverse conditions, e.g. caused by stirrers, filling
openings etc. can occur. The surfaces of the tuning
fork of VEGASWING 51 should be parallel to the
product movement/flow.
If there is gauge or low pressure in the vessel, the
mounting boss must be sealed on the thread. Before
use, please check if the seal material is resistant to
the medium.
Mounting boss with O-ring and welding notch.
VEGASWING 51 has a defined thread starting point.
This means that every VEGASWING is in the same
position after being screwed in. Remove therefore the
supplied seal from the thread of VEGASWING. This
seal is not required when using a mounting boss with
flush seal.
The mounting boss has already a notch. When
mounting horizontally, weld this socket with the notch
facing upwards or downwards, or in case of pipe-
lines, aligned with the direction of flow. Before you
start welding, unscrew VEGASWING and remove the
rubber ring in the mounting boss.

Moisture from outside
Mounting
To avoid moisture penetration, lead the connection
cable directly adjacent to the screwed cable entry
downward. Rain and condensation water can thus
drain off. This applies particularly when mounting
outdoors, in humid areas (e.g. by cleaning proc-
esses) or on cooled or heated vessels.

5.1 Preparing the connection
Always observe the following safety instructions:
• Connection only in the complete absence of line
voltage
VEGASWING 51 is connected with standard cable.
Depending on the plug connection, you have to se-
lect the cable diameter so that the seal effect on the
cable entry is ensured.
• valve plug DIN 43650, ø 4.5 … 7 mm
• valve plug QuickOn DIN 43650, ø 3.5 … 6.5 mm.
If strong electromagnetic interference is expected,
we recommend using screened cable. Screening
should be provided at both ends.
Use cable with round cross section and tighten the
cable entry.
When mounting outdoors, on cooled vessels or in
humid areas in which cleaning is done, e.g. with
steam or high pressure, sealing of the cable entry is
particularly important.

Power supply 20 … 253 V AC, 50/60 Hz or
20 … 253 V DC, Imax 250 mA
For direct control of relays, contactors, magnet
valves, warning lights, horns etc. The instrument
must not be operated without connected load
(switching in series), as the oscillator can be de-
stroyed when being connected directly to mains. Not
suitable for connection to low voltage PLC inputs.
The domestic current is temporarily lowered below
1 mA after switching off the load so that contactors,
whose holding current is lower than the constant do-
mestic current of the electronics (3 mA), are reliably
switched off.
