With the potentiometer you can adapt the switching point to the
solid. It is already preset and must only be modified in special
cases.
By default, the potentiometer of VEGAVIB 67 is set to
complete right position (>0.02 g/cm³ or >0.0008 lbs/in³). In
case of very light-weight solids, you have to turn the
potentiometer to the complete left position (>0.008 g/cm³ or
>0.0003 lbs/in³). Hence the VEGAVIB 67 will be more
sensitive and can detect light-weight solids more reliably.
For instruments detecting solids in water, these values are not
applicable. The potentiometer 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
acc. to the "Function chart" (max. - max. detection or overfill
protection, min. - min. detection or dry run protection).
We recommend connecting acc. to the quiescent current
principle (replay contact deenergizes when reaching the
switching point), because the relay takes on the same (safe)
condition if a failure is detected.
Control lamp for indication of the switching condition.
