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 eight
(8) minutes, and then the dryer will shutdown leaving the safety shutdown message (out of grain warning) dis-
played. Press the dryer power stop button to reset the panel, then press the start button.
UNLOAD ONE SPEED OPERATION
To check one speed operation place the unload switch in the one speed setting. Turn the metering roll dial 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 gear box. If the dry grain
take away auxiliary is wired to the dryer, it should start and rotate in the proper direction.
UNLOAD TWO SPEED OPERATION
To check two speed operation move the unload switch to the two speed position, change the low speed reading to
200 and high speed on 600. Adjust the moisture control (grain temperature) setpoint to a value lower then the
ambient temperature or until the moisture control switch light comes on. The metering roll speed is now controlled
by the low speed setting. Adjust the moisture control (grain temperature) setpoint to a value higher then the
ambient temperature or until the light goes out leaves the metering rolls controlled by the high speed setting.
METERING ROLL OPERATION
To check the metering roll operation turn the knob clockwise, and the metering roll speed should increase. Turning
either knob counterclockwise will decrease the speed. 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 60 seconds (default cleanout delay setting) after the switch is turned off to allow for
cleanout.
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 all the motor needs to start working again. You should not have any more
problems with this during the rest of your drying season.
Meter Roll 1 Speed Display
This is used to adjust the speed of the metering roll when the single speed automatic moisture control feature
of the dryer is in use.
This is used to:
• Set the speed of the metering rolls when the one speed automatic moisture control feature of the dryer is
utilized.
• Set the speed of the metering rolls during continuous flow operation or .
Just turn the meter roll adjustment knob and put the is in the single speed position, your display will now show
the following:
If you are finished with your adjustments, press the button. The screen will also return to the main
display if you don’t turn or press the knob for about 8 seconds.
