ELECTRIAL POWER SUPPLY
Autoflow to Drying Chamber Rotary Switches Interconnect
The three (3) 110V AC rotary switches located
in the drying chamber are used to inform the
computer on the location of grain in the drying
chamber. The rotary switch with the shortest
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 the dryer down if the drying chamber
empties unexpectedlly. 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. The Drying Chamber Rotary Switches us
110V AC to power the motor and 12V DC+ to switch a signal back to the computer. The 110V
AC, 110V N, and the 12V DC+ wires can be
jumped from rotary switch to rotary switch to lessen
the wires needed.
To wire the Drying Chamber Rotary
Switches to the Autoflow Control Box do the
following:
1) Run six (6) control wires from the
Autoflow Control Box to the Drying
Chamber Rotary Switches.
2) Connect the wires as shown in figure 23.
