Adjusting the Moisture Control
1. 5° on the moisture control will change the output moisture by about 1%. Example: With 100° set,
the result is 16% corn but 17% corn is desired. Reduce the moisture control setpoint temperature
by 5° to 95°. This should change the moisture out to about 17%. If you want the corn to come out
dryer, raise the temperature on the moisture control setpoint.
2. Four (4) sensors are averaged together for sensing moisture control temperature, one (1) on each
side of the dryer in the front, and one (1) on each side of the dryer in the back. They are located
about 1/3 of the way up the grain column from the bottom, and in from the side about 4''.
3. Grain temperatures can be monitored by pressing the mode select button.
4. The moisture control should stay on HIGH about 50% to 90% of the time. There is a broad range
that will work. It should switch from low to high and back again to maintain the desired moisture. A
control that does not switch will not maintain an evenly dried grain moisture when the incoming wet
grain moisture varies.
5. If the metering roll switches to LOW and stays there for long periods of time, both the High
and Low Speed Potentiometers should be slowed down 2% (20 points) and monitored for
further adjustment.
6. If the metering roll switches to HIGH and stays on HIGH more then 90% of the time, increase the
speed on both Potentiometers 2% (20 points) and monitor for further adjustment.
7. When adjusting the METER ROLL SPEEDS it is better not to change the speed more than 20 points
(2%) at a time.
8. Anytime a change is made, wait the approximate dry time for that moisture grain from the
before checking the grain moisture level and making another change if necessary.
