3.3 Applications
• The sensor continually monitors and adjusts to the medium� Thus it adapts
itself to different media and compensates for changes in the medium�
• For water and hydrous media with temperatures > 35°C install the unit into the
climatic tube (order no� E43100, E43101, E43102)�
The sensor is not suitable for:
• Very conductive and adhesive media (shampoo, toothpaste, glue, etc�)�
• Dry granulated materials with low density�
• Media which are very inhomogeneous, separate from each other thus forming
separation layers (e�g� oil layer on water which is several cm thick or a water
layer at the bottom of a vessel filled with oil)�
-Note: A thin oil film (a few mm) on water or water based media does not affect
the function of the sensor�
4 Operating modes
4.1 Run mode
Normal operating mode
After power on and elapsing of the power-on delay time* (approx� 1 s) the unit is in
the Run mode� It monitors and switches the transistor outputs according to the set
parameters�
The display indicates the current level, the red LEDs indicate the switching state
of the outputs�
*During the power-on delay time
is displayed�
4.2 Display mode
Indication of parameters and the set parameter values
When the "Mode/Enter" button is pressed briefly, the unit passes to the Display
mode which allows parameter values to be read� The internal sensing, processing
and output functions of the unit continue as if in Run mode:
• The parameter names are scrolled with each pressing of the "Mode/Enter"
button�
• When the "Set" button is pressed briefly, the corresponding parameter value is
displayed for approx� 15 s� After another 15 s the unit returns to the Run mode�
