VEGA VEGAWAVE 63 - transistor (NPN-PNP) - Manual (Page 21)

By default, the potentiometer of VEGAWAVE 63 is set to the right stop
(> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids, turn
the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/in³).
VEGAWAVE
63 will thus be more sensitive and can detect light-weight
solids more reliably.
For instruments detecting solids in water, these settings are not
applicable. The switching point adaptation is preset and must not be
changed.
With the mode switch (min./max.) you can change the switching status
of the transistor output. You can set the required mode according to
the "Function chart" (max. - max. detection or overflow protection, min.
- min. detection or dry run protection).
We recommend connecting according to the quiescent current
principle (switching output is opened when the switching point is
reached) because the transistor output takes on the same (safe)
condition if a failure is detected.

l Red = Output open
l red (flashing) = failure
