19. Run the fan(s) and heater(s) for about 10% longer than the (APPROX. DRYING TIME) required for the moisture you are
trying to dry.
20. Example: 10% removal would be about 54 minutes, 15% removal would be about 76 minutes and 20% removal would be
about 100 minutes. Add 10 minutes to insure that the grain is dry.
21. After the time in step 19 turn the UNLOAD AUGER switch to MANUAL. and set the METER ROLL SPEED, (MANUAL
SPEED). Remember that Manual is a true Manual operation, with no moisture control. The meter rolls will run at the speed that
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.
22. After the run time in step 21 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 will need to press the SETUP button again and return to the Hardware
Parameter screen. Press the M/C SETUP button and then press the CALIBRATE MOISTURE SENSORS button. The Moisture
Sensor Calibration window will appear (see image below). 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 screen read 17% the same
as your moisture tester.
Calibrate sensors by
touching the arrow
buttons.
