2.1 Authorised personnel
All operations described in this operating instructions
manual must be carried out only by trained and au-
thorised specialist personnel. For safety and warranty
reasons, any internal work on the instruments must
be carried out only by qualified VEGA personnel.
2.2 Appropriate use
VEGASWING 51 is a vibrating level switch for level
detection in liquids.
2.3 Warning about misuse
Inappropriate or incorrect use of the instrument can
give rise to application-specific hazards, e.g. vessel
overfill or damage to system components through
incorrect mounting or setting.
2.4 General safety instructions
VEGASWING 51 is a high-tech instrument requiring
the strict observance of standard regulations and
guidelines. The user must take note of the safety
instructions in this operating instructions manual, the
country-specific installation standards (e.g. the VDE
regulations in Germany) as well as all prevailing
safety regulations and accident prevention rules.

• NSR EN 61010-1: 2001.
2.6 Environmental instructions
Protection of the environment is one of our most im-
portant duties. That is why we have introduced an
environment management system with the goal of
continuously improving company environmental pro-
tection. The environment management system is
certified acc. to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the
environmental instructions in this manual:
• Chapter 3.3 Storage and transport
• Chapter 8.2 Disposal.

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).
