Continuous Flow Drying Mode Using Regulation of
Grain Temperature
Full Heat Continuous Flow Operation
This section begins with Step 7 and it is assumed that Step 1 through Step 6 in the start-up procedure
described on Page 58 have been completed. For this operation procedure we will say that incoming grain
moisture content is 25% and ten points of moisture removal is our goal.
7. Touch the Setup button at the bottom of the Default Operation Screen. Once the “Select Hardware
Setup Parameter to Modify” Screen is displayed, touch the Drying Mode button. When the “Drying
Mode Selection” window appears, touch the Continuous Flow button to select continuous flow drying
mode. Then, touch the Accept/Exit button and return to the “Select Hardware Setup Parameter to
Modify” Screen. Touch the M/C Setup button. When the “Moisture Control Selection” window
appears, select the REGULATION OF GRAIN TEMPERATURE moisture control option. Do not
select the 5 Speed option yet, as this will be explained later. Touch the Accept/Exit buttons and return
to the Default Operation Screen.

8. Make sure the Unload switch is OFF.
9. Open the main fuel supply valve on the tank if using LP gas, or the valve in the fuel supply line if using
natural gas. Open the manual shut off valve to allow fuel flow to the dryer.
10. The dryer should be filled with grain. Turn the Load Auger switch to the AUTO position. In both the
AUTO and MANUAL positions, the Dryer Grain Level switch will automatically keep the dryer full of
grain. In the AUTO position, the dryer will shutdown after a preset time period using the out of
grain timer.
11. Turn each Fan switch to ON. The fan will start and the switch will illuminate when air pressure
is detected.
12. Start each burner by turning the Heater switch ON. After purging for approximately 10 seconds, the
burner will fire and the Heater switch will illuminate. This indicates that the flame sensing circuit is
sensing burner flame. For information concerning burner adjustment, see the dryer pre-start check
section on
Page 46 of this manual. Set the plenum temperature setpoints to 180°F.
