3.2 Description of function
The voltage between the electrodes is approximately
12 V DC, and the operating voltage for the pump
connection is 1 x 230 V. The four electrode rods
extend into the liquid to be pumped at differing
lengths. The longest electrode functions as a frame
electrode; the second-longest is the stop electrode,
followed by the start electrode, the shortest electrode
being the alarm electrode.
The level controller is factory-set to emptying
function. If the liquid level rises to the start electrode,
the controller switches on the pump. If the liquid level
falls below the stop electrode, the controller switches
the pump off. If the liquid reaches the alarm
electrode, a potential-free contact in the control box
closes, and the built-in buzzer will sound. The
additional potential-free changeover contact is
provided for special applications and can also be
used for an external alarm. The position of the
contacts (spring terminals) on the guide plate in the
control box is shown in fig.
The function can be reversed by moving the cable
from connector X1-1 to connector X1-2, so that the
connected device turns on when the stop electrode
is reached, and turns off when the start electrode is
reached (filling function). The alarm is then triggered
when the tank to be filled is overfilled.
After installation, the level controller functions
automatically. Settings on the device must not be
adjusted.

4. Transport and storage
The level controller is delivered in appropriate
packaging and should remain packed until
installation.
The controller must be stored in a dry, cool, frost-free
space. The controller must not be exposed to direct
sunlight.
