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.
