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 al-
lows you to output the desired current.
Modes
•
min. - rising characteristic curve (High current when immersed)
•
max. - falling characteristics (Low current when immersed)
The NAMUR output can be switched over to falling or rising charac-
teristics (see also "Function table").
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 process-
ing unit is simulated. The signal lamp on the sensor extinguishes. The
measuring system must signal a fault and take on a safe state when
the key is pushed.
Keep in mind that downstream connected instruments will be acti-
vated during operation. This allows you to check the correct function
of the measuring system.
Control lamp (LED) for indication of the switching condition
•
yellow = High current ≥ 2.2 mA
•
dark = Low current ≤ 1.0 mA
•
yellow (flashing) = Failure ≤ 1.0 mA

Function table

Level switch VEGAVIB 63
The following table provides an overview of the switching conditions
depending on the set mode and the level.
Note:
The mode setting on the NAMUR amplifier must be selected in such
a way that the switching output takes on safe state in case of failure (I
≤ 1 mA).
