20. With the Unload Auger switch in the AUTO position, the moisture control is active. Press the
M/C button at the bottom of the Default Operation Screen. When the “Modify Temperature Setpoint”
window appears, set the upper temperature to about 130°F. Let the dryer run on these settings for
at least 30-40 minutes before making further adjustments to the moisture control or meter roll
settings. While these settings does not achieve grain moisture exactly as desired, they will serve as
a good starting point for adjusting the settings to reach the desired results. A slightly different
moisture at the bottom of the storage bin is not usually a problem if full floor aeration is present.
21. After the run time in
, adjust the moisture control and the meter roll speeds if required.
Each time an adjustment is made to the moisture control, it will take approximately the amount time
shown in PNEG-1650/PNEG-1651 to see the results of this adjustment. For every 5° change in
temperature, moisture will changed by one point.
So far only the 2 Speed meter roll option has been discussed. The 2 Speed meter roll option works well if
the grain entering the dryer has nearly the same moisture content. However, if the moisture content
of the grain entering the dryer varies greatly, then the 5 Speed option may be more beneficial. The
5 Speed option allows the user to set an inner and outer limit for the high and low meter roll settings as
well as an inner and outer limit for the moisture control temperature setting. When setting up the 5 Speed
meter roll option try to set it so that the dryer operates inside the inner limits as much as possible and use
the outer limit setting for extreme cases of incoming moisture content.
To enable the 5 Speed option, press the Setup button at the bottom of the Default Operation Screen. When
the Select “Select Hardware Setup Parameter to Modify” Screen appears, select the M/C Setup button.
When the “Moisture Control Selection” Screen appears, touch the Enable 5 SPD Temperature button.
Note that the 5 Speed box is checked.
