VEGA VEGAWAVE 61 - Relay (DPDT) - Manual (Page 19)

By default, the potentiometer of VEGAWAVE 61 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
61 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 adjustment (min./max.) you can change the switching
condition of the relay. You can set the required mode according to the
"F
unction chart" (max. - max. detection or overflow protection, min. -
min. detection or dry run protection).
We recommend connecting according to the quiescent current
principle (relay contact deenergizes when the switching point is
reached), because the relay always takes on the same (safe) condition
if a failure is detected.
