VEGA VEGAWAVE S 61 - Manual (Page 14)

If one of the stated malfunctions is detected or in
case of power failure, the electronics takes on a
defined switching condition, i.e. the relay deener-
gises (safe condition).
Functional principle
The tuning fork is piezoelectrically energised and
vibrates at its mechanical resonance frequency of
approx. 150 Hz. When the tuning fork is sub-
merged in the product, the vibration amplitude
changes. This change is detected by the integrated
oscillator and converted into a switching command.

3 .1 General instructions
Switching point
In general, VEGAWAVE S 61 can be installed in
any position. The instrument simply has be
mounted in such a way that the vibrating element is
at the height of the desired switching point.
Moisture

Transport
Do not hold VEGAWAVE S 61 on the vibrating
element. Remove the protective cover just before
installation.
Handling
The vibrating level switch is a measuring instru-
ment and must be treated accordingly. Bending the
vibrating element will destroy the instrument.
Warning:
The housing must not be used to screw the
instrument in! Applying tightening force can
damage internal parts of the housing.
Use the hexagon above the thread for
screwing in.

Installation instructions
Socket
The vibrating element should protrude into the
vessel to avoid buildup.
Filling opening
Mount the instrument in such a way that the tuning
fork does not protrude directly into the filling
stream.
