DRYER PRE START CHECKS
The metering roll access area.
iary is wired to the dryer, it should start
and rotate in the proper direction.
MOISTURE CONTROL
THERMOSTAT
To check the moisture control ther- mostat leave the unloading switch on one speed, and slowly turn down the moisture control thermostat. As the setting is decreased, the indica- tor light should come on and the me- tering rolls should stop operating. The bottom auger will stop after the 30 second clean out delay, provid- ing that the dryer is still being held by the moisture control thermostat. Rotate the moisture control thermo- stat 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.
TWO SPEED OPERATION
To check two speed operation move the switch to the two speed position, set low speed on 200 and high
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 cor- rect direction 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 one speed operation place the unload switch in the one 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 gear box. If the dry grain take away auxil-
speed on 600. Slowly turn the ther- mostat until the moisture control switch light comes on. The meter- ing roll speed is now controlled by the low speed dial. Turning the ther- mostat the other way until the light goes out leaves the metering rolls con- trolled by the high speed dial.
METERING ROLL

To check the metering roll operation turn either the low speed or high speed knob clockwise, and the metering roll speed should increase. Turning ei- ther knob counterclockwise will de-
