VEGA VEGAVIB 61 - two-wire - 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.
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 determine the output
current.
When using a VEGATOR signal conditioning instrument, always set
the mode switch to max. mode.
In this case you select the requested mode according to the "Function
chart" (max. - max. detection or overfill protection, min. - min.detection
or dry run detection) on the VEGATOR signal conditioning instrument.
When used on a control system, the following values apply:
l Mode min.
-
Vibrating element uncovered - 16 mA ±1 mA
-
Vibrating element covered - 8 mA ±1 mA
l Mode max.
-
Vibrating element uncovered - 8 mA ±1 mA
-
Vibrating element covered - 16 mA ±1 mA
Control lamp for indication of the switching status
l green = 8 mA
l red = 16 mA
l red (flashing) = Failure (< 2.3 mA)
