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").
For applications acc. to WHG, the DIL switch must be set to
position max.
With this DIL switch (3) you can set the switching point to
liquids having a density between 0.5 and 0.7 g/cm³ (0.018 and
0.025 lbs/in³). With the basic setting, liquids with a density of
>0.7 g/cm³ (>0.025 lbs/in³) can be detected. In liquids with
lower density, you must set the switch to >0.5 g/cm³
(>0.018 lbs/in³). The specifications for the position of the
switching point relate to water - density value 1.0 g/cm³
(0.036 lbs/in³). In products with a different density, the
switching point will shift in the direction of the housing or tuning
fork end depending on the density and type of installation.
The simulation key is located in a recess on the upper side of
the oscillator. 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 the connected (downstream) instruments will
be activated during operation. This allows you to check the
correct function of the measuring system.
