Load Auger
With the grain supply shut off, quickly bump the Load Auger switch to MANUAL and see if the load auger
rotates clockwise, as viewed from the drive end, or counterclockwise if the dryer is a front load model.
If the wet grain supply auxiliary is wired to the dryer it should also rotate in the correct direction at this time.
Turn the Load Auger switch to the AUTO position. The top auger and wet grain supply auxiliary should
run for one minute and then the dryer will shutdown leaving the safety shutdown message (out of grain)
displayed. Press the Dryer Power Stop button to reset the panel, then press the Start button to
resume operation.
1 Speed Operation
To check 1 Speed operation, place the Unload switch in the 1 Speed setting. Turn the high speed metering
roll dial up until the metering rolls start rotating. The bottom auger should rotate counterclockwise, as
viewed from the drive end. The metering roll drive motor should rotate clockwise, as viewed from the drive
end of the gearbox. If the dry grain take away auxiliary is wired to the dryer, it should start and rotate in
the proper direction.
Metering Roll Operation
To check the metering roll operation, turn high speed knob clockwise. The metering roll speed should
increase. Turning the knob counterclockwise will decrease the speed. Turn ON the Moisture Control switch.
If the grain temperature setpoint is set above the outside temperature, the system will switch to Low Speed
if working correctly. Make sure the drive chain tension is properly adjusted and all sections of the metering
rolls rotate. Turn the Unload switch OFF after these checks are complete. The bottom auger will continue
to run for 30 seconds after the switch is turned OFF to allow for clean out.
