Autoflow Operation
Dryer Control Panel Featuring the
Electronic Monitoring Control System
The control panel provides easy access to gauges
and controls, and the illuminated switches provide a
quick reference for every operating function. The
patent pending Electronic Monitoring Control
System is a computerized control system that gives
instant information regarding dryer operation.
Moisture Control Thermostat
This electronic thermostat controls the moisture
level of discharged grain by sensing grain column
temperature using the four (4) RTD temperature
sensors located in the drying chamber. The moisture
control thermostat indicates the current grain
temperature in the drying chamber with LEDs. The
grain temperature setpoint is set on the moisture
control thermostat. In the Autoflow mode, when the
grain temperature reaches the grain temperature
setpoint, and the dry timer has reached zero, the
dryer will dump the third driest portion of grain
from the drying chamber into the storage chamber.
In the Autobatch mode the dryer will dump all of the
grain into the storage chamber.
Moisture Control Switch
This switch turns the power on or off to the moisture
control thermostat. When placed in the “on”
position, the dryer will not enter the dump cycle
until the grain temperature has reached the grain
temperature setpoint on the moisture control thermo-
stat and the dry timer has reached zero. When
placed in the “on” position, the moisture control
switch lights up when the grain temperature is below
the grain temperature set point on the moisture
control thermostat. When placed in the “off”
position, the dryer ignores the grain temperature and
operates strictly off the dry timer. When placed in
the “off” position, the moisture control switch does
not light up.
Control Power Switch
The power to the Electronic Monitoring Control
System is turned on or off with the control power
CONTROL SYSTEM
switch. The switch lights up when placed in the
“on” position. If the switch is placed in the “on”
position, and the light does not light up, make sure
that the emergency stop switches located on the
Autoflow control box is pulled out.
24-Volt Power Switch
This switch turns the power on or off to the actuator
control box. The switch lights up when placed in the
“on” position. If the switch is placed in the “on”
position, and the light does not light up, make sure
that the emergency stop switch located on the
actuator control box is pulled out (1997 model only).
Aeration Fan Switch
This switch controls the operation of the aeration fan
located at the bottom of the bin. The switch lights
up when the aeration fan comes on. When placed in
the “auto” position, the aeration fan starts and stops
with the main drying fans. When placed in the “off”
position, the aeration fan will not run. When placed
in the “on” position, the aeration fan comes on when
the dryer is running.
Load Auger Switch
This switch controls the operation of the fill
system(s) that load grain into the drying chamber.
The switch lights up when the fill system(s) are
running. When placed in the “auto” position, the fill
system(s) start and stop automatically depending on
the level of grain relative to the drying chamber high
level rotary switch. When operating in the
Autobatch mode, the fill system(s) will shut off 2/3
(two-thirds) of the way through the dry cycle, even
if grain has not reached the drying chamber high
level rotary switch. When placed in the “off”
position ,the fill system(s) will not run. When
placed in the “on” position, the fill system(s) come
on and stay on when the dryer is running.
Fan Switch
This switch controls the operation of the main
drying fan(s). The switch lights up when the
airswitch located in the sidewall next to the master
