Mode of Operation
Max. and min. control of
discharging.
Example 1
The diagram shows the level
control connected as max.
and min. control, i.e. detec-
tion of 2 levels. The relay
operates when the max. elec-
trode is in contact with the li-
quid. The relay releases when
the min. electrode is no
longer in contact with the li-
quid. By use of a container of
a conductive material (pin 7)
can be connected to the con-
tainer. If the container is made
of a non-conductive material,
an additional electrode is
needed, indicated by the dot-
ted line in the diagram.
Example 2
If only one level is required,
pins 5 and 7 must be inter-
connected to select either
max. or min. control.
