INSTALLATION
Drying Chamber Rotary Switches Mounted in Bin Roof
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.
