you select using the Meter Roll Speed Encoder. To do this push on the Meter Roll Adjustment knob. When the Modify Meter
Roll Setpoints window appears turn the Meter Roll Adjustment knob until the speed indicator is set to the speed suggested for 1
SPEED. Grain should begin to run at this time. Run time for this is about 10% longer than the (APPROX. DRYING TIME)
required for the moisture you are trying to dry. This allows the moisture in the dryer to reach an even gradient top to bottom
without having any highs or lows in it. It will however, over dry some of the grain a little.

21. After the run time in step 20 begin to test the moisture content with a Moisture Tester you consider to be accurate. Test at
least 3 samples for accuracy. Having determined the average discharge moisture, you may now calibrate the incoming and
outgoing moisture sensors on the dryer. To do this you need to touch the SETUP button again and return to the Hardware
Parameter screen. Touch the M/C SETUP then touch the CALIBRATE SENSORS button. Follow the example below to adjust
the dryer to your moisture tester.

Example: Your moisture tester gives you an average moisture of 17% but the moisture sensor on the dryer is reading
18.3%. You would then calibrate the dryers moisture sensor (-1.3%), that would make the moisture sensor read 17%
the same as your moisture tester.

22. Once the moisture reading at the discharge is where you want it to be, turn the UNLOAD switch to AUTO.

23. Now that the UNLOAD AUGER switch is in the AUTO position the ADVANCED MOISTURE CONTROL is active. Now
touch the M/C button at the bottom of the Dryer Operation screen. When the Moisture Setpoint window appears set the
moisture setpoint to the output moisture you desire. Let the dryer run on these settings before trying to adjust moisture or meter
roll settings.

24. The dryer will run in MANUAL for the first 30 minutes after you turn the AUTO position. This will again make sure that
the grain is flowing through the dryer on an even basis. After the 30 minute period the Moisture Control will automatically

Calibrate sensors by
touching the arrow
buttons.
