The area between the bottom of the vessel and the lower face of the
measuring probe can be entered as offset value. Thus the display and
the switch points refer to the real vessel level.
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
outputs according to the set parameters.
The display indicates the current level, the red LEDs indicate the switch-
ing state of the outputs.
*During the power-on delay time
is displayed.
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.
