VEGA VEGAVIB 61 - Relay (DPDT) - Manual (Page 20)

As a default setting, the potentiometer of VEGAVIB 61 is set to the
complete right position (> 0.3 g/cm³/0.011 lbs/in³). In very light solids
you have to turn the potentiometer to the complete left position
(0.02 … 0.1 g/cm³ or 0.0007 … 0.0036 lbs/in³). By doing this,
VEGAVIB
61 will be more sensitive and light solids can be detected
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.
