5.2 Adjustment elements
Density adaptation
With this DIL switch, the switching point can be set
to bulk solids having a density between 0.1 and
0.3 g/cm³.
As default setting, the switch of VEGAVIB S 61 is
set to the large weight symbol (> 0.03 g/cm³). In
very light solids you should turn the DIL switch to
the small weight symbol (0.1 ... 0.3 g/cm³). By
doing this, VEGAVIB S 61 is more sensitive and
can detect light solids reliably.
Mode adjustment
With the mode adjustment (min./max.) you can
change the switching condition of the relay. You
can set the required mode according to the
"Function chart" (max. - max. detection or overfill
protection, min. - min. detection or dry run
protection).
We recommend connecting according to the
quiescent current principle (relay contact deener-
gizes when the switching point is reached),
because the relay always takes on the same (safe)
condition if a failure is detected.
