Load Auger
With the grain supply shut off, quickly flip 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 8 minutes. The dryer will then shutdown and the safety shutdown message: Out of grain will display.
Press the Stop button to reset the panel, then press the Start button.
Unload Auto Operation
To check Auto operation, place the Unload switch in the AUTO position. Push then turn the meter roll dial
to a setting of 500 and touch ACCEPT/EXIT to start the meter roll rotation. The bottom auger should rotate
counterclockwise as viewed from the drive end. The meter 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.
Unload Manual Operation
To check Manual operation, move the Unload switch in the MANUAL position. Push then turn the meter
roll dial to a setting of 500 and touch ACCEPT/EXIT to start the meter roll rotation. The bottom auger
should rotate counterclockwise as viewed from the drive end. The meter 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.
Meter Roll Operation
Meter Roll Operation 4" (GSI)
When the meter rolls are set to maximum (1000), the meter roll speed should be 17.5 RPM for 8'' (20 cm)
discharge augers. Make sure the drive chain tension is properly adjusted and all sections of the meter rolls
rotate. Turn the Unload switch OFF after these checks are complete. The bottom auger will continue to
run for 60 seconds (the default clean out delay setting) after the switch is turned OFF to allow for clean out.
Meter Roll Operation 7" (FFI)
To check the meter roll operation turn the knob clockwise and the meter roll speed should increase.
Turning the knob counterclockwise will decrease the speed. When the meter rolls are set to maximum
(1000), the meter roll speed should be 4.3 RPM for 8" (20 cm) discharge augers. Make sure the drive chain
tension is properly adjusted and all sections of the meter rolls rotate. Turn the Unload switch OFF after
these checks are complete. The bottom auger will continue to run for 60 seconds (default clean out delay
setting) after the switch is turned OFF to allow for clean out.
NOTE: Due to the nature of the DC drive motor used on the meter rolls, it is possible for the brushes inside
the motor to become corroded if the dryer has not been operated for several months. This will
cause the meter rolls not to function. To fix this problem, use a rubber mallet or a piece of wood to
tap the DC drive motor. The shock is usually sufficient to re-start the motor and metering rolls. You
should not have any more problems with this during the rest of the drying season.
