Control Power Switch
Turn the control power switch on. The
switch will light up. The screen will display a
copyright message and software version number,
total running time in hours and minutes and the
model number, and the serial number and current
time and date. At this time, the controller will lock
out all other dryer functions. Once the date and
time are displayed, press the reset button and the
dryer will perform its safety circuit check. If a
fault is found, an error message will be displayed
on the screen. If all are found safe, the main
drying screen will be displayed.
Drying Chamber
Enter the drying chamber and inspect each
dump hopper for obstructions that may inhibit the
flow of grain into the dump chutes. Make sure that
the gap between the discharge flow plates and the
floor sheets is a minimum of 1-1/2”. All discharge
flow plates should be adjusted evenly around the
bin. Inspect each discharge flow plate and make
sure that the bottom brackets on each flow plate
have not collapsed, due to pressure from walking
around the drying chamber. Inspect the leveling
bands. Make sure that all leveling bands are
installed properly and are in good shape.
Rotary Switches
View the drying chamber switches from
the peak hole on top of the dryer. Make sure that
all three rotary switches are spinning freely.
Double check the seal on each rotary switch top.
The number one cause of switch failure is water.
Make sure when the electricain replaced the top on
the rotary switch that no creases formed in the
gasket. Inspect both the storage and wet supply
rotary switches for operation and proper seal.
Dump Chutes
Enter the storage chamber. Make sure that
all dump chutes are adjusted evenly. When one
chute is level, make sure that all chutes are level.
This is very critical to the correct operation of the
dryer. The center plate, that all the dump chute
chains attach to, should be no greater than 12”
from the pulley when the chutes are level. If the
center plate is further than 12” from the pulley
when the chutes are closed, the chains must be
lengthened.
Linear Actuator
Turn the dump switch on the Autoflow
control box to the “manual open” position. Use a
