gear box. If the dry grain take away auxiliary is wired to the dryer, it should start and rotate in the proper direction.

MOISTURE CONTROL

THERMOSTAT

To check the MOISTURE CON- TROL THERMOSTAT leave the UNLOADING switch on 1 SPEED, and slowly turn down the MOIS-

TURE CONTROL THERMOSTAT. As the setting is decreased, the in- dicator light should come on and the metering rolls should stop operat- ing. The bottom auger will stop af- ter the 30 second clean out delay, providing that the dryer is still being held by the MOISTURE CONTROL THERMOSTAT. Rotate the MOIS-

TURE CONTROL THERMOSTAT up to its maximum setting. The light should go off, and the metering rolls should restart along with the bottom auger if it has stopped.

To check 2 SPEED operation move the switch to the 2 SPEED po-

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 coun- terclockwise 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 di- rection at this time. Turn the LOAD AUGER switch to the AUTO posi- tion. The top auger and wet grain supply auxiliary should run for one minute, and then the dryer will shut down 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.

ONE SPEED OPERATION

To check 1 speed operation place the UNLOAD switch in the 1 SPEED setting. Turn up the HIGH SPEED METERING ROLL DIAL until the metering rolls start rotating. The bottom auger should rotate coun- terclockwise as viewed from the drive end. The metering roll drive motor should rotate clockwise as viewed from the drive end of the

sition, set LOW speed on 200 and HIGH speed on 600. Slowly turn the thermostat until the MOISTURE CONTROL switch light comes ON. The METERING ROLL SPEED is now controlled by the LOW speed dial. Turning the THERMOSTAT the other way until the light goes out now leaves the metering rolls controlled by the HIGH SPEED DIAL.
