Autoflow Operation

restarted  by pressing the start switch.  When the

start switch is pressed the screen on the 

Dryer

Control Panel 

will read “Press Enter to Dry

Remaining Grain”.  If the enter button is pushed

the dryer will restart without running the fill

system(s).  The dryer will remain running until the

completion of the next 

Dump Cycle

, after which an

“Out of Grain” error is displayed on the 

Dryer

Control Panel

 and the dryer stops.

If the 

Storage Chamber High-Limit Rotary

Switch 

becomes covered with grain during the

Dump Cycle

 the dryer will continue through the

Dump Cycle

 and will continue to the next

 Dry

Cycle

.  When the 

Dry Cycle

 is complete the unit

will not continue to the 

Dump Cycle

.  A “Storage

THEORY OF OPERATION/TERMINOLOGY

Chamber Full” error will be displayed on the

screen and the dryer will stop.  The unit will not

dump automatically until grain has been removed

from the 

Storage Chamber.

If the dryer stops for any reason the 

Aera-

tion Fan

 will remain running if the 

Aeration Fan

Bypass

 switch is placed in the “continuos” posi-

tion.  The 

Aeration Fan Bypass

 switch is located in

the side of the 

Fill System Control Box.

  If the

Aeration Fan Bypass

 switch is placed in the

“automatic” position the

 Aeration Fan

 stops

whenever the dryer stops.

Items in Italics are Defined in the

Dryer Terminology Section

Top Dry Autoflow Terminology

Actuator Control Box

-The actuator control box

houses the linear actuator that controls the dump

chutes.  The actuator also houses the two 12vDC

batteries and the 24vDC battery charger.  The

actuator control box is mounted to the bin

sidewall.

Aeration Fan

-The aeration fan is located at the

bottom on the outside of the bin and is used to cool

grain in the storage chamber.  The aeration fan is

designed to deliver about 1/4 cubic feet of air per

minute per bushel of grain in the storage chamber.

The motor starter for the aeration fan is located in

the Fill System Control Box.

Aeration Fan Bypass Switch

-The aeration fan by

pass switch is located on the side of the fill system

control box.  When the aeration fan bypass switch

is placed in the “continuos” position the aeration

fan does not shut off with the dryer.  When the

aeration fan bypass switch is placed in the “auto-

matic” position the aeration fan shuts off when the

dryer stops.

Aux. 1 Delay

-The aux. 1 delay is used in both

single fill and double fill systems.  The aux. 1

delay is located on the dryer control panel next to

the display screen.  In single fill systems the aux. 1

delay controls how long fill system #1 runs after

grain reaches the drying chamber high level rotary

switch.  In units with two fill systems the aux. 1

delay controls how long fill system #1 runs after

fill system #2 shuts off.  This allows fill system #2

to clean out before stopping.

Airswitch

-The airswitch is used to tell the com-

puter when the drying fan(s) have started so the

burner can be ignited or remain ignited.  The

airswitch is attached to the master drying fan and

is mounted in the bin sidewall even with the

master drying fan.  The airswitch operates by

sensing the increase in static pressure in the bin

after the drying fan(s) have started.  In two fan

units the airswitch should be adjusted so that it

does not close until after the slave fan reaches half

speed.
