• 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 sev-
eral 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.
Normal operating mode
After power on and elapsing of the power-on delay time* (approx. 1s)
the unit is in the Run mode. It monitors and switches the transistor
output according to the set parameters. The value of the analog out-
put depends on the current level.
The display indicates the current level, the red LED indicates the switch-
ing state of the output.
*During the power-on delay time
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 inter-
nal 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 para-
meter value is displayed for approx. 15s. After another 15s the unit
returns to the Run mode.
Setting of the parameter values
While viewing a parameter value pressing the "Set" button for more
than 5s causes the unit to enter the programming mode. You can alter
the parameter value by pressing the "Set" button and confirm the new
value by pressing the "Mode/Enter" button. The internal sensing, pro-
cessing and output functions of the unit continue as if in Run mode
with the original parameter values unless a new value is confirmed.
The unit returns to the Run mode when no button has been pressed
for 15s.
