Heater Switch
The burner is turned ON or OFF with this switch. Turning the switch to the ON position will start the
burner ignition sequence if the fan is also running. Turning the switch to the OFF position turns the
burner OFF. The light inside of the switch will illuminate only when the flame sensor detects the burner
flame. (
NOTE: The heater AUTO position is not used for continuous flow operation.
)
Load Auger Switch
This switch is used to select the operation of the wet fill conveyor. In both the AUTO and the MANUAL
positions, the wet fill conveyor will operate if the dryer is low on grain and will automatically shut off
when the dryer is full. In the AUTO position only, the dryer will automatically shut down should the dryer
go low on grain. The time period between the dryer going low on grain and the actual shut down is
determined by the setting on the out of grain timer. In the MANUAL position, the out of grain timer is
deactivated. The MANUAL switch position should be used for initially filling the dryer. The AUTO
switch position should be used during normal dryer operation. The switch will illuminate whenever the load
auger is operating.
Unload Switch
The Unload switch turns the accutrol metering system and the unload auger ON or OFF and also selects
the operation of the metering system. In the MANUAL position, the metering system operates at the speed
set by the Metering Roll Speed Rotary switch. In the AUTO position, the metering system
switches to a multi-speed operation controlled by the automatic moisture control. The switch will illuminate
whenever the unload auger is operating.
Outside Light Switch
The service light is turned ON or OFF with this switch. In the AUTO position, the light is turned ON
while the dryer is running automatically and turns OFF if a shut down occurs. In the ON position, the light
is turned ON.
Start Switch
This switch starts and operates the dryer. If all of the above Dryer Operational switches are in the OFF
position, each component can be turned ON by turning the Component switch to the ON position after the
Run switch has been pressed. Or, if the Operational switches are preset to their ON position, the vision
controls will sequentially start the various dryer components after the Run switch is pressed.
Stop Switch
This switch stops all dryer functions except the blower. If the Blower switch is in the ON position, the blower
will continue to run for 15 minute. If you desire the blower to be OFF, simply turn the Blower switch to the
OFF position. If an automatic dryer shut down occurs, first determine and correct the cause of the shut
down. Then press the Dryer Power Stop button to reset the dryer before restarting.
