2000 Autoflow
INSTALLATION
The three (3) Drying Chamber Rotary Switches are used by the series 2000 Autoflow to monitor the location of grain in the Drying Chamber. The rotary switch with the shortest shaft extension is the Drying Chamber Overflow Rotary Switch. It is used as a safety in the event the Chamber High Level Rotary Switch fails. The rotary switch with the longest extension is the Drying Chamber Low Level Rotary Switch. It is used to inform the computer when the peak has been covered with grain so the drying process can begin; and, will shut down if the drying chamber empties unexpectedly. The third rotary switch is the Drying Chamber High Level Rotary Switch. It is used to inform the dryer when the drying chamber is full so loading can stop.
When mounting the Drying Chamber Rotary Switches some foresight is needed. The Drying Chamber Rotary Switches should be located in close proximity to one another to lessen the amount of conduit and wiring required. The rotary switches should also be mounted so that they are
located in an area of the drying chamber that fills evenly with the rest of the drying chamber. The component placement on page 9 shows the placement of the Drying Chamber Rotary Switches in relation to the Fill System #1 transport auger/ downspout.
The rotary switches should NOT be located in a part of the drying chamber that fills unevenly with the rest of the drying chamber. If the area of the drying chamber where the rotary switches are located fills faster that the rest of the drying chamber the drying chamber will not fill to capacity and uneven drying will result. If the area of the drying chamber where the rotary switches are located fills slower than the rest of the drying chamber an overflow situation may occur.
It is very critical that the drying chamber fill evenly and that the grain falls from Fill System #1 directly onto the perforated cone in the drying chamber.
