Setting the Load Delay
The value set on the load delay is the amount
of time that fill system number two runs after grain
reaches the drying chamber high level rotary switch.
This delay is not used with only one fill system con-
trolled by the Autoflow. The load delay should be set
long enough so that the drying chamber high level
rotary switch is covered with enough grain that the fill
system do not start and stop frequently in the dry cycle
due to settling or shrinkage; but, the load delay should
be set short enough so that grain does not reach the
drying chamber overflow rotary switch. The load
delay is set using the same procedure as the dry and
unload timers, but the reset button does not need to be
pressed to enter the new values into memory immedi-
ately.
Setting the Aux. 1 Delay
In units that the Autoflow controls one fill
system, the value set on the aux. 1 delay is the amount
of time that fill system number one runs after grain
reaches the drying chamber high level rotary switch.
The aux.1 delay should be set long enough so that the
drying chamber high level rotary switch is covered
with enough grain that the fill system does not start and
stop frequently in the dry cycle due to settling or
shrinkage; but, the aux. 1 delay should be set short
enough so that grain does not reach the drying chamber
overflow rotary switch.
In units that the Autoflow controls two fill
systems, the value set on the aux. 1 delay is the amount
of time that fill system number one runs after fill
system number two shuts off. Fill system number one
is the fill system that directly puts grain in the drying
chamber. The aux. 1 delay should be set long enough
so that all grain present in fill system number one is
loaded into the drying chamber before it shuts off.
This will decrease the current required to start fill
system number one the next time the dryer calls for
grain. The aux. 1 delay is set using the same procedure
as the dry and unload timers, but the reset button does
not need to be pressed to enter the new values into
memory immediately.
Setting the Unload Delay
The value set on the unload delay is the
amount of time that both fill system number one
and fill system number two run after grain falls
away from the wet supply rotary switch before the
unit shuts down and gives a wet supply hopper
“empty” error. In units that the Autoflow controls
only one fill system, the value set on the unload
delay is the amount of time that fill system number
one runs after grain falls away from the wet supply
rotary switch. The unload delay should be set long
enough so that the fill system(s) clean out before
the dryer shuts down; but, should be set short
enough to avoid running the fill system (s) empty
for an excessive amount of time. The unload delay
is set using the same procedure as the dry and
unload timers, both the reset button does not need
to be pressed to enter the new values into memory
immediately.
Setting the Aux. 2 Delay
The aux. 2 delay is not currently being
used.
Viewing operation time and total cycles
The total operation time and total cycles
can be viewed at any time the dryer is in the main
drying screen by pressing the increase button.
Diagnostics Mode-Resetting Batch Counter
The Electronic Monitoring Control System
can perform a self-diagnostic exam. With the dryer
stopped and in the main drying screen, press and
hold down the reset button for several seconds.
After the self-diagnostic exam is complete, the
display will read the results of the exam and will
then give the user the option to reset the batch
counter. The batch counter can be cleared by
pressing the reset button or left as-so by pressing
the enter button. After choosing an option, the user
is taken to the shutdown history retrieval. To view
past shutdowns and the time and date the shutdown
occurred, press the decrease button. Press the enter
button at any time to return to the main drying
screen.
