The control power to energize the Network Control System is turned on or off with this switch.
Note: This switch does not disconnect the power that is present at the breakers, contactors,
transformer(s), fuses or other electrical components found in the upper and lower control boxes. Turn the
Main Disconnect Handle to the OFF posistion prior to servicing any of the installed components.
This is used to select staged batch or continuous flow drying. The switch will light only after the Network Control
System has been turned on, the safety circuit is okay and the button on the control panel has been
pressed.
This is used to select the operation of the fill auger. In both the auto and manual position the load auger 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 shut down after a preset period of time set on the out of grain timer, or if grain flow is interrupted to the
dryer. The switch will light whenever the load auger is operating.
Note: If the load auxiliary controls are being used, this switch will also control the operation of the auxil-
iary equipment.
Each fan is turned on or off with this switch. The on position operates the fan continuously during staged batch
and continuous flow modes. The auto position operates the fan in staged batch during the dry and cool cycle but
the fan will not operate during the unload cycle. The switch will light up whenever the air pressure switch is sensing
air pressure and the dryer is full of grain.
Note: The bottom fan on your dryer is always Fan 1.
Each burner is turned on or off with this switch. The auto position operates the burner in staged batch during the
dry cycle only. The on position will operate the burner only when the fan is running. The switch will light up only
when the flame sensor detects the flame.
Note: The bottom burner on your dryer is always Burner 1.

The unload switch turns the metering rolls and discharge auger on or off, and selects the operation of the metering
rolls.
• In the 2 speed position if the moisture control switch is on, and the drying mode switch is turned to cont. flow, the
metering roll speed will alternate between the high speed metering roll potentiometer setting and the low speed
metering roll potentiometer setting depending on whether the grain temperature is above or below the grain
temperature setpoint. The discharge auger will operate continuously.
• In the 1 speed position, if the moisture control switch is on, and the drying mode switch is turned to cont. flow,
the metering roll speed will discharge grain at the high speed metering roll potentiometer setting or turn off the
meter rolls depending on whether the grain temperature is above or below the grain temperature setpoint. The
discharge auger will operate whenever the metering rolls are operating.
• In both the 1 speed or the 2 speed position, if the moisture control switch is off, and the drying mode switch is
turned to cont. flow, the metering roll speed can be manually controlled by adjusting the high speed metering roll
potentiometer. The discharge auger will operate continuously.
• If the drying mode switch is turned to staged batch, the unload switch should be set to the 1 speed position. The
discharge auger and metering rolls will only operate during the unload cycle of the staged batch operation, and the
speed of the metering rolls is adjusted using the high speed metering roll potentiometer.
Note: If the unload auxiliary controls are being used, this switch will also control the operation of the
auxiliary equipment.
