Grain
The grain temperature set-point is set here.
Use the increase and decrease buttons to change the
grain temperature setpoint. Press the enter button
when done.
Screens
By pressing the screens button you can toggle
between two screens. Screen #1 displays the current
plenum and grain temperatures and their setpoints in
parenthesis. Screen #2 displays the status of the drying
chamber rotary switches and the total number of
batches. In all screens the dry time and dump time are
displayed at the bottom of the screen.
# OF FILL SYSTEMS - Use the increase and decrease
buttons to toggle between one or two fill systems.
Press the enter button when the number of fill systems
displayed on the screen equals the number of fill
systems that the computer will be controlling. If one
fill system is selected only one fill system will be
controlled by the computer. The Fill 1 delay will be
used to delay the shut off of the fill system after the
drying chamber is full. The Fill 2 delay will have no
effect on the operation of the fill system. If two fill
systems are selected two fill systems will be controlled
by the computer. Both the Fill 1 delay and the Fill 2
delay are used by the computer to delay the shut- off of
the fill systems after the drying chamber is full.
SELECT DRYER TYPE - Use the increase
and decrease buttons to select one of the six model
types that fits your system. The six models are as
follows:
AF3 - Autoflow with three main drying fans
AF2 - Autoflow with two main drying fans
AF1 - Autoflow with one main drying fan
AB3 - Autobatch with three main drying fans
AB2 - Autobatch with two main drying fans
AB1 - Autobatch with one main drying fan
Most systems will be either an Autoflow with
one fan or an Autoflow with two fans. Press the enter
button when the correct model number is displayed.
SELECT TEMP SCALE - Use the increase and
decrease buttons to toggle between Fahrenheit or
Celsius. Press the enter button when the correct scale
is displayed.

BURNER DIFFENTIAL - Use the increase
and the decrease buttons to change the burner differen-
tial. The burner differential is the span in degrees
between high fire and low fire When the temperature
in the dryer reaches the plenum temperature setpoint
plus the differential the burner will cycle from high fire
to low fire. When the temperature in the dryer falls to
the plenum temperature setpoint minus the differential
the burner will cycle from low fire to high fire. Ex-
ample: Plenum temperature setpoint = 180 degrees,
temperature differential set to 5 degrees. The burner
will cycle from high fire to low fire at 185 degrees and
will cycle from low fire to high fire at 175 degrees.
