Level Control (Fixed Measuring Points)
The level sensor measures the presence of material at five different points.
If the melter is heated up and there are no undertemperature faults or
sensor alarms (short-circuit / sensor break), the command to fill is given as
soon as the level falls below the measuring point Start filling.
Filling continues until the measuring point Stop filling is reached.
The status diode Filling is illuminated during filling.

Filling, the warning Tank level low and the fault Tank empty can only be
triggered when the heaters are switched on. Filling stops when sensor
alarms occur or the main contactor or level control is switched off.
Level control is activated
Level control is deactivated.
Level display and monitoring no longer occur. Filling, the warning Tank level

Now the tank can be emptied for maintenance or repair work without the
fault Tank empty occurring.
