Adjustment elements
The diode (2) can be checked with closed
housing. To adjust VEGAVIB, loosen the four
screws on the upper side of the housing with a
screwdriver and remove the housing cover.
The oscillators allow the following settings:
• A/B mode, only with oscillators C, R and T;
with oscillator Z: switch over via the signal
conditioning instrument
• sensitivity setting with potentiometer (not with
VEGAVIB 31)
With the A/B switch (4) you can change the
switching condition of the contactless electronic
switch (C), the relay output (R) or the transistor
output (T) . You can set the required mode acc.
to the "Function chart". A - max. level detection
or overfill protection, B - min. level detection or
dry run protection.
With oscillator Z the A/B mode can be switched
via the signal conditioning instrument. Note the
setup of the signal conditioning instrument.
With the potentiometer (5) you can change the
switching sensitivity and adapt it to the density
of the product. This is necessary for detection of
extremely light or heavy products. Turn the
potentiometer anticlockwise to make the vibrat-
ing probe more sensitive. Normally, a modifica-
tion of the default setting will only be necessary
with extremely light products.
With adhesive products, it might be necessary
to turn the potentiometer clockwise to achieve a
better oscillation.
For most products, it is not necessary to change
the setting of the preset potentiometer (default
setting of the potentiometer = 5).
To modify the integration time, you have to use
oscillator Z in conjunction with a suitable signal
conditioning instrument (VEGATOR 534, 536,
537 and 636).
The instrument version for detection of solids in
water is adapted for use in water and cannot be
used for normal level detection. Adjustment of
the settings of the instrument is identical.
