Series 2000 Autoflow Operation
Start Up Procedure
At the beginning of each harvest and before
filling the dryer with grain make sure to inspect the
dryer for rodent damage, and system integrity. Enter
the drying chamber and check each dump hopper.
Remove any obstructions. Test operate the dryer using
the pre-season checklist.
There are two fundamental things to control
with the Autoflow Top Dry (or any dryer); the drying
rate and the grain flow rate. Drying rate is determined
by the dryer size and shape, the grain to be dried, the
airflow rate, and the drying air temperature. We
consider the best temperature to be the highest one
where the desired grain quality is maintained. Corn
used for livestock consumption is dried at a maximum
recommended temperature of 200 degrees Fahrenheit.
Corn used for different applications, and other grains
may require lower drying temperatures. By selecting a
drying air temperature a drying rate is established. To
achieve a desired final grain moisture content, the grain
flow rate is adjusted to match the drying rate.
Initial Dryer Start Up
1) Be sure the control power switch is off. Turn on the
main power supply disconnect for the Autoflow control
box, fan and heaters, and all fill systems.
2) Pull out the emergency stop switches on the
AUTOFLOW THEORY/
START UP PROCEDURE
If the Wet Storage Tank becomes empty
while the fill systems are running, the Fill 1 and Fill 2
Delays starts to count down. When the Fill 1 and Fill 2
Delays reach zero the fill system(s) shut off along with
the dryer and a Wet Supply Hopper Empty “Out of
Grain” error is displayed on the Dryer Control Panel
screen. If there is grain against the Drying Chamber
Low Level Rotary Switch the unit can be restarted by
pressing the start switch. When the start switch is
pressed the screen on the Dryer Control Panel will read
“Press Enter to Dry Remaining Grain”. If the enter
button is pushed the dryer will restart without running
the fill system(s). The dryer will remain running until
the completion of the next Dump Cycle, after which an
“Out of Grain” error is displayed on the Dryer Control
Panel and the dryer stops.
If the Storage Chamber High-Limit Rotary
Switch becomes covered with grain during the Dump
Cycle the dryer will continue through the Dump Cycle
and will continue to the next Dry Cycle. When the Dry
Cycle is complete the unit will not continue to the
Dump Cycle. A “Bin Grain Hi Limit” error will be
displayed on the screen and the dryer will stop. The
unit will not dump automatically until grain has been
removed from the Storage Chamber.
If the dryer stops for any reason the Aeration
Fan will remain running if the Aeration Fan Bypass is
enabled. The Aeration Fan Bypass is set in the Set-up
mode. If the Aeration Fan Bypass is disabled the
Aeration Fan stops whenever the dryer stops.
Autoflow control box, fill systems control box, and the
actuator control box.
3) Set the switches on the Autoflow control box as
follows:
MOISTURE CONTROL switch - “On”
AERATION FAN switch - “Auto”
LOAD AUGER switch - “Off”
FAN switch - “Auto”
HEATER switch - “Auto”
DUMP switch - “Auto”
DRY and HOLD switch - “Off”
4) Make sure there is wet grain in the wet supply tank.
5) Turn the control power switch to the “on” position.
6) The screen will display a copyright message and
software version number.
