VEGA VEGAWAVE 61 - NAMUR - Manual (Page 20)

By default, the potentiometer of VEGAWAVE 61 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).
VEGAWAVE
61 will thus be more sensitive and can detect light-weight
solids more reliably.
For instruments detecting solids in water, these settings are not
applicable. The switching point adaptation is preset and must not be
changed.
The characteristics reversal can be carried out with the DIL switch.
You can choose between falling characteristic curve (switch position
max.) and rising characteristic curve (switch position min.). This allows
you to output the desired current.
Modes
l min. - rising characteristic curve (High current when immersed)
l max. - falling characteristics (Low current when immersed)
The NAMUR output can be switched over to falling or rising
characteristics (see also "Function chart").
The simulation key is located in a recess on the upper side of the
electronics module. Push the simulation key with a suitable object
(screwdriver, pen, etc.).
When the key is pushed, a line break between sensor and processing
unit is simulated. The signal lamp on the sensor extinguishes. The
measuring system must signal a fault and take on a safe condition
when the key is pushed.
Keep in mind that downstream connected instruments will be activated
during operation. This allows you to check the correct function of the
measuring system.

l yellow = High current ≥ 2.4 mA
l dark = Low current ≤ 1 mA
l yellow (flashing) = Failure ≤ 1 mA

Level switch VEGAWAVE 61
The following chart provides an overview of the switching conditions
depending on the adjusted mode and level.
Note:
The mode setting on the NAMUR amplifier must be selected in such a
way that the switching output takes on safe condition in case of failure
(I ≤ 1 mA).
