VEGASWING 71A and 75A 13
Setup
4 Setup
4.1 Switching status
The switching status can be checked with
closed instrument by means of the illuminated
ring in the upper part of the housing.
By interchanging of the connection cables,
you can modify the switching status of the
transistor output (T). For the electronics ver-
sion contactless electronic switch (C) you
have to use a jumper in the plug between
terminal 2 and 3 to modify the switching sta-
tus. You can adjust the requested mode acc.
to "4.3 Functions chart" (see "3.2 Connection
plan").
A = max. detection or overfill protection,
B = min. detection or dry run protection.
4.2 Switching point
The switching point of VEGASWING 71A and
75A is preadjusted and does not require
further modifications.
The statements on the position of the switch-
ing point (see also "2.1 Mounting instruc-
tions") relate to water (density 1.0 g/cm
3 ). For
mediums with a different density, this switch-
ing point shifts, depending on the density
and the installation, in the direction of the
housing or tuning fork tip.
A density change of 0.1 g/cm 3 results in a
shifting of the switching point by approx.
2.5 mm.
4.3 Functions chart
The following chart provides an overview of the switching conditions dependent on the ad-
justed mode and level. To set the mode, please read the information in "3.2 Wiring plan".
