3. Functions of the control centre
3.1 Switches and buttons
3.1.1 Operation switch
The dryer's operating mode is selected using the switch (1). Irrespective of the position of the selector switch, the
following safety features are active:
The feeder can only be started, while the elevator and the bottom screw are running. The blower remains switched
on until the inlet air temperature drops below 45 °C.
Positions:
Position 0
The appliances are standing still.
Note! Turning the switch to position 0 during the drying phase will not stop
the machinery, if the burner is running, and the inlet air temperature is higher
than 45 ºC.
Position E
Enables the appliances in the filling and emptying chain of the dryer to be
operated. If the switch is in this position, you can, for example, operate the
elevator, the filling conveyor or the discharge conveyor. The position E is
meant for filling and emptying of the dryer as well as for transferring the grain
by some other means.
Position A
This position is used for automated drying of the grain. The drying phase
is controlled by the value set on the outlet air temperature display, and the
cooling phase is controlled by the time set in the cooling timer.
Position K
Drying the grain with manual control. The manual control must only be used
under constant supervision. During manual control, neither the outlet air tem-
perature nor the cooling timer controls the drying process. It is also possible
to stop the feeder during the drying.
During drying, it is possible to turn the operation switch between positions A and K without the appliances being
stopped. This makes it possible, for example, to stop the feeder momentarily for filling the fresh grain silos during
the drying phase.
