8. Dryer Operation
Dryer Start-up
1. Before attempting to operate the dryer, make sure all safety shields are in place, the burner is
uncovered, all column clean-out doors are closed, the four (4) metering access doors are closed,
the drain valve in the fuel train is closed and all personnel are clear of the dryer and grain
handling machinery.
2. Turn all selector switches on the control panel to the OFF position.
3. Turn ON the electrical power supply to the dryer and move the dryer’s main breaker disconnect
handle mounted on the dryer’s power box to the ON position.
4. Turn the Control Power switch located on the control panel to the ON position. The switch will
illuminate. At this point, the controller will lock out all other dryer functions. Once the Boot screen
appears, touch the Start Dryer button. The dryer will perform a safety circuit check. If no faults are
found, the dryer is ready to be started.
5. Move the Load Auger switch to the MANUAL and push the Dryer Start switch. The load auger will
immediately start and the Load Auger switch will illuminate. If additional loading equipment is wired
to the dryer it will also start-up.
6. When the dryer is full of grain the load auger will stop automatically and any auxiliary loading
equipment wired to the dryer will also stop.
7. Move the Load Auger switch to the AUTO position to activate the out of grain timer. (See
for adjusting the out of grain timer.)
8. Open the main fuel valve on the propane tank or the natural gas fuel supply line. Open all manual
fuel shut off valves on the dryer.
9. Turn the Fan switch to the ON position. The fan will start and the light in the switch will illuminate
when air pressure in the dryer is detected.
10. Turn the Heater switch to the ON position. After a purge period of approximately 30 seconds, the
burner will fire and the Heater switch will illuminate when the flame sensing circuit is sensing flame.
For initial burner testing set the plenum temperature to 140°F using the “setting temperatures”
procedure found
. For normal drying operations, use the following guidelines for setting
the drying temperature:
a. Shelled corn (20% to 30%) --- 210°F to 220°F.
b. Shelled corn (15% to 20%) --- 180°F to 200°F
c. Small grains (wheat, oats, barley or milo) --- 150°F
d. Soybeans -- 130°F.
e.
NOTE: As a general rule for obtaining the highest drying efficiency, use the highest drying
temperature which will not adversely affect grain quality.
Set the drying temperature to the desired level.
11. Look in the reference setting tables
and select the appropriate table for the dryer and
grain moisture levels. Turn the Unload Auger switch to MANUAL position. The unload auger and
metering system will start discharging grain from the dryer. Push the Metering Roll Speed switch and
turn the knob to adjust the speed to that suggested in the setting tables. (
NOTE: Make sure to press
the “Accept/Exit” button on the Metering Roll screen when changing metering roll speed to lock in the
new speed.)
