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.
