KROHNE OPTISWITCH 3200C Contactless EN - Manual (Page 21)

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 OPTISWITCH 3200 C 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). OPTISWITCH 3200 C will
thus 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 output. 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 (contactless electronic switch is open when the
switching point is reached) because the contactless electronic
switch takes on the same (safe) condition if a failure is
detected.
Control lamp for indication of the switching condition.
