5. Turn all Fan switches to On.
The fans start and the switches are illuminated once air pressure is detected.
Tip
It is recommended to start fans one at a time, and to let each fan attain their respective speed before
starting the next one.
6. Turn all Heater switches to On, and confirm that all plenum setpoints are set (see
).
After a 15-second purge for safety reasons, the burners ignite and the switches are illuminated.
7. Run the burners for the drying time indicated in the drying operation’s respective startup settings (see
Initial Settings for Full-Heat and Dry and Cool, page 78
When establishing drying times, the rule of thumb is to dry grain for five to seven minutes for each point of
moisture you need to remove. Let’s assume that the wet grain has a moisture content of 25%, a target of
15%, and that you are running a full-heat operation. According to the startup settings, you need to dry
grain for 54 minutes.
If running dry and cool, turn off the bottom heater once the drying time elapses, and run the dryer for an
additional 10 minutes so that the grain can cool.
After You Finish
Unload grain in manual mode before switching to auto mode (see
Unloading Grain in the Initial Run, page
). For information on drying grain in auto mode, see
Drying Grain in Continuous Flow, page 57
(for con-
tinuous flow) or
Drying Grain in Staged Batch, page 63
(for staged batch).
Unloading Grain in the Initial Run
For the initial run, unload the dry grain in manual mode so that you can validate the outgoing moisture con-
tent and establish an appropriate unload rate prior to switching to auto mode.
Before You Begin
• Make sure to set all required parameters; see
Powering On the Dryer, page 27
for information on
which parameters to set.
• If running dry and cool, ensure that the set drying time and cooling time have elapsed (see
Grain in the Initial Run, page 32
for details).
What You Should Know
In manual mode, only one unload speed is available, regardless of the chosen control scheme; whereas in
auto mode (Unload Auger switch in the Auto position), you can enter unload speeds in the settings
window of the chosen control scheme.
To unload grain in the initial run:
1. From the menu pane, click Unload→Unload Speed.
The Unload Speed in Manual Mode window opens.
2. Set the following parameters:
Unload Speeds Entered in — The units of measure (bushels or metric tons per hour, or metering
roll speed %) that the unload speed value is entered in.
