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.
