Electronic Monitoring Control System
The Electronic Monitoring Control System
controls all timing functions and safety circuit checks.
It is designed to simplify dryer operation by providing
printed messages and warnings on its liquid crystal
display (LCD).
Turning On The Electronic Monitoring Control
System
Turn the control power switch to the “on”
position. The monitor will display a copyright mes-
sage, software version number and will enter the main
drying screen.
Setting The Dry, Cool And Unload Timers
These switches are used to set the dry, cool and
dump cycle times. The current settings on these timers
are displayed directly above their timer button. To
change the setting of these timers do the following:
1) Press the dry, cool or unload timer button.
2) Press the modify button.
3) Press the increase or decrease button to
adjust the settings.
4) Press the enter button.
5) To enter the new value into memory imme
diately, press the reset button.
During operation the remaining time on each
timer is displayed on the screen. If the power goes out
or the dryer is stopped these times are saved by the
controller. When the dryer is restarted the timers will
continue timing down. The timers will return to their
initial settings by pressing the reset button. The cool
timer is not used in an Autoflow system.

Setting The Delays
AUX. 1 DELAY - The AUX. 1 DELAY is not
used.
REFILL DELAY - The REFILL DELAY is
used only on batch units. It is the amount of time that
the unit has to refill after the dump cycle. If the unit
does not refill before the time on the refill delay is at
zero the unit will give a “dry chamber empty” error.
FILL 1 DELAY - In units that the Autoflow
controls one fill system, the value set on the fill 1 delay
is the amount of time that fill system number one runs
after grain reaches the drying chamber high level rotary
switch. The fill 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 fill 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 fill 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 fill 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 fill 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.
