Drying Chamber Overflow

The grain level in the drying chamber has

reached the drying chamber overflow rotary

switch. Grain will have to be dumped from the

drying chamber to the storage chamber before the

unit can be restarted. This error indicates that

either the drying chamber high level rotary switch

is faulty or the time on the Load delay or Aux.1

delay needs to be lowered. Electrically there is the

presence of 12vDC+ on J4-6 on the input/output

board.

Storage Chamber Full

The grain level in the storage chamber has

reached the storage chamber high level rotary

switch located 3 feet(.91 meters) below the fan and

heater(s). Grain will have to be removed from the

storage chamber before the unit can be restarted.

Electrically there is the presence of 12vDC + on

J4-4 on the input/output board.

Wet Supply Hopper Empty

The grain in the wet supply tank has fallen

below the wet supply rotary switch. If there is

grain against the drying chamber low level rotary

switch, the dryer can be restarted by pressing the

stop switch to clear the error and then the start

switch. Electrically there is a loss of 12vDC+ on

J4-2 on the input/output board.

Wet Supply Empty Press<Enter>to

Dry Remaining Grain

This message is displayed when the start

button is pushed and grain has fallen away from

the wet supply rotary switch and there is still grain

against the drying chamber low level rotary

switch. If the enter button is pushed, the dryer will

restart, but the fill system(s) will not restart.

Electrically there is a loss of 12vDC+ on J4-2 and

the presence of 12vDC+ on J4-8 on the input/

output board.

Out of Grain Warning

This message is displayed after the dump cycle

when the dryer has been restarted by pressing the

enter button, after a “wet supply empty error” has

been given.

Cannot Start Dryer Wet Supply Empty

This message is displayed when the start button is

pushed and grain has fallen away from the wet

supply rotary switch and there is no grain against

the drying chamber low level rotary switch. Grain

will have to be put into the wet supply tank or the

drying chamber to start the dryer. Electrically

there is a loss of 12vDC on J4-2 and a loss of

12vDC+ on J4-8 on the input/output board.

Drying Chamber Low Grain

This message is displayed when grain falls

away from the drying chamber low level rotary

switch after the Aux. 1 timer has reached zero. If

the error is being caused due to the settling of

grain after the fans start, the time on the Aux.1

timer can be lengthened. Electrically there is a

loss of 12vDC+ on J4-8 on the input/output board.

Load Auger Motor Overload

The thermal overload in the fill system control box

for fill system number one has tripped, indicating

an overcurrent condition. Make sure the emer-

gency stop switch on the fill system control box is

pulled out as this will inhibit the motor starter

from engaging. The overload must be reset manu-

ally. Electrically there is a loss of 12vDC+ on J4-

16 on the input/output board.
