6 Setup
VEGAVIB 61 • Two-wire 8/16 mA
29268-EN-170315
As a default setting, the potentiometer of VEGAVIB 61 is set to the
complete right position (> 0.3 g/cm³/0.0011 lbs/in³). In very light
solids you have to turn the potentiometer to the complete left posi-
tion (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 ap-
plicable. The density range 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
table
" (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:
•
Mode min.
– Vibrating element uncovered - 16 mA ±1 mA
– Vibrating element covered - 8 mA ±1 mA
•
Mode max.
– Vibrating element uncovered - 8 mA ±1 mA
– Vibrating element covered - 16 mA ±1 mA
Control lamp for indication of the switching status
•
green = 8 mA
•
red = 16 mA
•
red (flashing) = Failure (< 2.3 mA)
