SAFETY PRECAUTIONS
READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
1.
Read and understand the operating manual before trying to operate the
dryer.
2.
Power supply should be OFF for service of electrical components. Use
CAUTION in checking voltage or other procedures requiring power to
be ON.
3.
Check for gas leaks at all gas pipe connections. If any leaks are detected, do not operate the dryer. Shut down and repair before further
operation.
4.
Never attempt to operate the dryer by jumping or otherwise bypassing
any safety devices on the unit.
5.
Set pressure regulator to avoid excessive gas pressure applied to burner
during ignition and when burner is in operation. Do not exceed maximum recommended drying temperature.
6.
Keep the dryer clean. Do not allow fine material to accumulate in the
plenum or drying chamber.
Series 2000 Autoflow Operation
Use Caution in the
Operation of this
Equipment
The design and manufacture of this
dryer is directed toward operator
safety. However, the very nature of
a grain dryer having a gas burner,
high voltage electrical equipment
and high speed rotating parts, does
present a hazard to personnel, which
can not be completely safeguarded
against, without interfering with efficient operation and reasonable access to components.
Use extreme caution in working
around high speed fans, gas-fired
heaters, augers and auxiliary conveyors, which may start without
warning when the dryer is operating on automatic control.
7.
Use CAUTION in working around high speed fans, gas burners, augers
and auxiliary conveyors which START AUTOMATICALLY.
8.
Do not operate in any area where combustible material will be drawn into
the fan.
9.
Before attempting to remove and reinstall any propellor, make certain to
read the recommended procedure listed within the servicing section of
the manual.
10.
Clean grain is easier to dry. Fine material increases resistance to airflow
and requires removal of extra moisture.
This product is intended for the use of grain handling only. Any other
use is considered a misuse of the product.
Some edges of the product components can be sharp. It is recommended
that each component of this product be examined to determine if there
are any safety considerations to be taken. Any and all necessary personal
protective equipment should be worn at all tines when handling, assembling, installing and operation of the product and/or components.
Guards are removed for illustration purpose only. All guardsmust be in
place before/during operation.
KEEP THE DRYER CLEAN
DO NOT ALLOW FINE
MATERIAL TO ACCUMULATE
IN THE PLENUM CHAMBER
OR SURROUNDING THE
OUTSIDE OF THE DRYER
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the
owner. For a safe and dependable
drying system, follow the recommendations within this manual, and
make it a practice to regularly inspect the operation of the unit for
any developing problems or unsafe
conditions.
Take special note of the safety precautions listed above before attempting to operate the dryer.

ELECTRICAL POWER SUPPLY
Power Supply
An adequate power supply and proper wiring are important factors for maximum performance and long life of
the dryer. Electrical service must be adequate enough to
prevent low voltage damage to motors and control circuits (see Electrical Load Information).
Transformer and Wiring Voltage Drop
It is necessary to know the distance from the unit to the
available transformer, and the horsepower of your fan
unit. Advise the service representative of your local power
supplier that an additional load will be placed on the line.
Each fan motor should be wired through a fused or circuit breaker disconnect switch. Check on KVA rating of
transformers, considering total horsepower load. The
power supply wiring, main switch equipment and transformers must provide adequate motor starting and operating voltage. Voltage drop during motor starting should
not exceed 14% of normal voltage, and after motor is
running at full speed it should be within 8% of normal
voltage. Check Electrical Load Information for HP ratings and maximum amp loads to properly size wire and
fusing elements. Standard electrical safety practices and
codes should be used. (Refer to National Electrical Code
Standard Handbook by National Fire Protection Association).
Machine to Earth Grounding
It is very important that a
Rod
be installed at the fan. This is true even if there is
a ground at the pole 15 feet away. Place the ground
rod that comes standard, within 8 feet of the dryer
and attach it to the dryer control panel with at least a
#6 solid, bare, copper ground wire and the clamp provided. The grounding rod located at the power pole
will not provide adequate grounding for the dryer. The
proper grounding will provide additional safety in case
of any short and will ensure long life of all circuit
Machine To Earth Ground
Series 2000 Autoflow Operation
boards, and the ignition system. The ground rod must
be in accordance with local requirements.
Proper Installation of Ground Rod
It is not recommended that the rod be driven into dry
ground.
Follow these instructions for proper installation:
1.
Dig a hole large enough to hold 1 to 2 gallons of
water.
2.
Fill hole with water.
3.
Insert rod through water and jab it into the ground.
4.
Continue jabbing the rod up and
ter will work its way down the hole, making
it possible to work the rod completely into
the ground. This method of installing the
rod gives a good conductive bond with the sur
rounding soil.

CONTROL PANEL
Series 2000 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 Switch
This switch determines if the grain temperature
setpoint is used in the operation of the dryer. When
placed in the “on” position the dryer will not enter the
dump cycle until the grain temperature has reached the
grain temperature setpoint 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 setpoint.
When placed in the “off” position the dryer ignores the
grain temperature and operates strictly off of the dry
timer. When placed in the “off” position the moisture
control switch does not light up.
the “on” position the aeration fan comes on when the
dryer is running.
If the Aeration Fan Bypass is enabled in the Set-up, the
aeration fan remains running when the aeration fan
switch on the dryer control panel is placed in the “on”
position. With the aeration fan switch placed in the
“auto” position the aeration fan will stop any time the
dryer stops.
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 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) work the same as in
Auto, except the Out of Grain Timer is ignored.
Control Power Switch
The power to the Electronic Monitoring Control
System is turned on or off with the control power
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, and Fill System control box are pulled out.
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
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 drying fan senses an
increase in static pressure and closes. In the Autoflow
mode, when placed in the “auto” position the main
drying fan(s) start when grain reaches the drying
chamber low level rotary switch and do not stop until
the dryer shuts down or is stopped manually by pressing the stop switch. In the Autobatch mode the main
drying fan(s) shut off automatically in the dump cycle.
When placed in the “off’ position the main drying
fan(s) will not run. When placed in the “on” position
the main drying fan(s) come on and stay on when the
dryer is running.

Series 2000 Autoflow Operation
Heater Switch
CONTROL PANEL
This switch controls the operation of the burner(s).
The switch lights up when the burner is on. When
the burner is on small lights above and below the
heater switch indicate if the burner(s) are in high
fire or low fire. In the Autoflow mode, when
placed in the “auto” position, the burner(s) fire
when grain reaches the drying chamber low level
rotary switch and do not stop until the dryer shuts
down or is stopped manually by pressing the stop
switch. In the Autobatch mode the burner(s) shut
off automatically in the cool and dump cycle.
When placed in the “off” position the burner(s)
will not fire. When placed in the “on” position the
burner(s) fire anytime the main drying fan(s) are
running.
Dump Switch
This switch controls the operation of the linear
actuator housed in the actuator control box. The
switch lights up when the linear actuator is moving. When placed in the “manual close position”
the linear actuator in the actuator control box
retracts- raising the dump chutes. When placed in
the “auto” position the linear actuator extends at
the beginning of the dump cycle- lowering the
dump chutes, and retracts at the end of the dump
cycle- raising the dump chutes. When placed in
the “manual open” position the linear actuator extendslowering the dump chutes.
Dry And Hold Switch
When placed in the “on” position the grain in the
drying chamber will not be dumped into the storage
chamber at the end of the dry cycle, and the dryer will
stop and cool for as long as the cool timer is set. If no
cooling is desired set to 0. This switch can be used to
hold the last batch of grain in the drying chamber and
stop the dryer. When placed in the “off” position the
dryer will operate normally. The switch lights up when
placed in the “on” position.
Dryer Power Start Switch
This switch starts and operates the dryer based on
switch settings. The switch lights up when the dryer is
running. The dump switch is disabled after this switch
has been pushed.

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 message, 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.
Setting The Delays
The Following Delays are set by pressing the
Delays Button
WET BIN SWITCH DELAY - If the Wet
Supply Rotary Switch is exposed this delay must expire
before a warning is given.
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.
This delay is not shown in Autoflow Mode.
HI LEVEL SW DELAY - The value set on the
HI LEVEL SW delay is the amount of time that fill
system runs after grain reaches the drying chamber
high level rotary switch. The HI LEVEL SW 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 HI
LEVEL SW delay should be set short enough so that
grain does not reach the drying chamber overflow
rotary switch.
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 on A Autoflow system except when in
Cool Down Mode. The Cool Timer is used to determine
how long the Top Dry will cool at shutdown. If no Cool
Down is desired set Timer to 0. Upon any of the
following conditions the system will go into cool down
mode.
1) Out Of Grain Timer Warning
2) Storage Chamber Full Warning
3) Low Level Switch Exposed Warning
4) Wet Bin Switch Exposed Warning
13
Page 14
CONTROL SYSTEM
Series 2000 Autoflow Operation
FILL 1 DELAY - This delay is not used in units with
only one fill system controlled by the Autoflow. 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.
LOW LEVEL DELAY - The value set on the
low level delay acts as a buffer to allow grain to fall
away from the drying chamber low level rotary switch
after the drying fans start without giving an error.
When grain reaches the drying chamber low level
rotary switch the drying cycle starts (if the fan switch is
placed in the “auto” or “on” position) and the low level
delay begins to time down. If grain falls away from the
drying chamber low level rotary switch before the time
on the low level delay reaches zero no error is given
and the dryer continues in the drying cycle. If grain falls
away from the drying chamber low level rotary switch
after the low level delay reaches zero a low level
switch exposed error is given and the dryer shuts down.
The low level delay should be set long enough so that
the fill system(s) have sufficient time to make up the
grain that falls away from the drying chamber low level
rotary switch when the fan(s) and heater(s) start; but,
should not be set too long. If the low level delay is set
too long and the linear actuator failed to retract, an
unacceptable amount of wet grain could flow from the
drying chamber to the storage chamber before a low
level switch exposed error is given and the dryer shuts
down. The low level 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.
MOTOR DELAY - The motor delay is the
delay in seconds between the starting of the master fan
unit and the slave fan unit. In systems with 220v1ph
electrical power the fan delay should be set at small
value - less than 3 seconds. If the motor delay is set
too long the slave fan could rotate fast enough backwards to start in a reverse rotation. Use the increase
and decrease buttons to select the motor delay. Press
the enter button when the correct motor delay is
displayed to continue to the main drying screen. In
single fan units the motor delay is not applicable.
FANS OFF DELAY - The fans off delay
allows the fan and heater unit(s) to be shut down
during the dump cycle. This will prevent the drying
floor from becoming excessively dirty when there is a
large amount of foreign material present in the grain
being dried. There are two values that the fans off
delay can be set at presently: 1:00 and 0:00. Use the
increase and decrease buttons to select the value.
When set at 1:00 the fan and heater units will shut off
during the dump cycle. When
at 0:00 the fan and heater unit(s) will not shut off and
the unit will operate normally.

ERROR MESSAGES
Error Messages
When the dryer shuts down the user can
quickly determine what caused the shutdown by
viewing the display on the dryer control panel. The
Electronic Monitoring Control System displays the
error message and sounds a warning signal to alert the
user. The displayed error conditions and their electrical cause are as follows:
Burner 1 Loss Flame
The flame sensor in burner number one has
failed to detect flame. Either the burner failed to light
or the flame sensor needs to be adjusted. The flame
sensor is the sensor attached to the burner, and has a
single lead. If the burner is lighting but the unit is still
shutting down due to loss of flame the flame sensor
needs to be adjusted. The flame sensor can be adjusted
by bending it so it is immersed in flame. If the burner
is not lighting make sure that the dryer is getting fuel,
all solenoids are opening, and the ignitor is sparking.

Pre-Season Checks
Before the dryer is filled, thoroughly inspect
the unit and check the operation of the dryer as follows. When entering the bin take great caution. Never
enter a bin where grain is present.
Set Control Switches
MOISTURE CONTROL Switch - “On”
AERATION FAN Switch - “Off”
LOAD AUGER Switch - “Off”
FAN Switch - “Off”
HEATER Switch - “Off”
DUMP Switch - “Auto”
DRY and HOLD Switch - “Off”
All Emergengy Stop Switches must be pulled
out. These are located on Fan Heater, Main Control
Panel, Fill System Box, and Actuator Box.
Grain High Limit
The grain temperature in the drying chamber is
too high. The grain temperature reached a point where
it was five degrees less than the plenum cycle setpoint.
Control Power Switch
Turn the control power switch on. The switch
will light up. 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 in are good shape.
21
Page 22
PRE-SEASON CHECKS
Rotary Switches
View the drying chamber rotary 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
electrician 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 that 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 tape measure
to measure the stroke on the linear actuator. The stroke
should be between 16” and 18”. If the stroke on the
actuator is not 16” to 18” the actuator should be
adjusted. Make sure that all pulleys and cables are
move freely when the actuator is moving. With the
actuator extended enter the storage chamber. View
each dump chute individually. Make sure that each
dump chute opened completely when the actuator
extended. If a dump chute does not open completely
the double nuts on the bolt that the chutes hinge on need
to be loosened. The dump chutes should hinge
smoothly. After the chutes have been inspected turn
the Dump switch on the Autoflow control box to the
“Auto” position and press the stop switch. The chutes
should raise.
Series 2000 Autoflow Operation
Power Start Button
Before the dryer start button is pushed make
sure there is grain in the wet supply tank. If there is no
grain in the wet supply tank the dryer will not start.
Push the dryer start button. The screen should no
longer be flashing “STOPPED”.
Fuel Check
If using LP gas, make sure the tank has plenty
of fuel. If using natural gas, make sure an adequate
supply is available. If using LP gas, slowly open the
main fuel supply valve at the tank. If using natural gas,
turn on the valve along the supply line. Then open the
ball valve on the fan heater unit(s). Inspect all gas
lines and connections for possible leaks. Any gas leaks
need to be fixed immediately!
Fan
Make sure that all toggle switches on the fan
and heater units are on. Bump the fan switch on the
Autoflow control box and observe the fan rotation.
The fan should run counterclockwise. Sometimes on
three phase models the motor will run backwards. This
can easily be reversed by first turning off the power at
the main disconnect, then interchanging any two of the
three power supply wires coming into the motor starter
in the fan control box. Reverse the two outside wires,
L1 and L3, and leave the middle one in the same
position.
Aeration Fan
Bump the aeration fan switch on the autoflow
control box and observe the aeration fan rotation. The
aeration fan should run counterclockwise. Sometimes
on three phase models the motor will run backwards.
This can easily be reversed by first turning off the
power at the main disconnect, then interchanging any
two of the three power supply wires coming into the
motor starter in the fill system control box. Reverse
the two outside wires, L1 and L3, and leave the middle
one in the same position.

Fill System
PRE-SEASON CHECKS
Prepare the wet storage tank to deliver grain to
the dryer. Make sure all personnel are away from any
machinery that is controlled by the Autoflow. Place the
load auger switch in the “Auto” position. The fill
system(s) should begin to load grain from the wet
supply tank to the dryer. When the display on the
Autoflow control box reads “GRAIN LOW LEVEL
YES” close the valve that supplies the fill system(s)
with wet grain from the wet supply tank. After the fill
system(s) have cleaned out place the load auger switch
in the “off” position.
Airswitch
Place the fan and heater service switches on
the main drying fan(s) in the “off” position. Place the
fan switch on the Autoflow control box in the “on”
position. Place the aeration fan switch on the Autoflow
control box in the “on” position. Go to the master fan
and heater unit. Place the fan service switch in the
“on” position. The master fan should start. In two fan
units the slave fan should start after the fan delay. In
single fan units the display on the master fan will read
airflow after the master fan reaches half speed. If the
display reads airflow before the fan reaches half speed
adjust the airswitch by turning it clockwise. If the
display does not read airflow adjust the airswitch by
turning it counterclockwise. In two fan units the
display on the master fan should read airflow after the
slave fan reaches half speed. If the display reads
airflow before the fan reaches half speed adjust the
airswitch by turning it clockwise. If the display does
not read airflow adjust the airswitch by turning it
counterclockwise.
fan(s) if they are not already running. Make sure the
fuel supply is on. The burner should ignite after a short
purge delay. Gas pressure should be shown on the
gauge. Adjust the high fire gas pressure by turning the
regulator in and out on LP units; or, by opening and
closing the main ball valve on natural gas units. The
high fire pressure should be approximately 6-15 lbs.
For LP units and 6-10 lbs. For natural gas units.
While the heater is in low fire adjust the low fire gas
pressure by opening or closing the ball valve located
on top of the pipetrain. The low fire gas pressure
should be approximately 2-6 lbs. For LP units and 1-3
lbs. For natural gas units. If the burner remains in high
fire and does not cycle, increase the gas pressure in
order to reach the plenum cycle setpoint. If the burner
remains in low fire and does not cycle, slightly decrease the gas pressure at the low fire gas valve. Any
time the high fire gas pressure is adjusted the low fire
gas pressure needs to be checked. The basic rule-ofthumb for setting gas pressure is as follows: make sure
that the temperature in the bin is increasing at a rapid
rate when in high fire, and the temperature in the bin is
falling at a rapid rate while in low fire.
Dryer Shutdown
To shut down the dryer, first close the fuel
supply valve at the tank or the valve along the fuel
supply line. If the burner is operating, let the dryer run
out of fuel. It should shut down due to loss of flame.
Press the dryer stop button to clear the error, and turn
off the main power disconnect at the entrance panel.

When the Top Dry is in a ready state; that is,
with no grain in the Drying Chamber and wet grain
in the Wet Storage Tank, Fill System #1 and Fill
System #2 will start to fill the Drying Chamber with
wet grain when the start switch is pressed on the
Dryer Control Panel. In single fill system units only
Fill System #1 will start. When grain reaches the
Drying Chamber Low Level Rotary Switch the
Aeration Fan, and the Master Drying Fan will come
on, and the Fan Delay will start to count down.
When the Fan Delay reaches zero the Slave Drying
Fan will start, the Airswitch will close, and the Dry
: “enabled”
Timer will start to count down. In single fan units the
Fan Delay will not count down and the Airswitch will
close after the Master Drying Fan starts. After a
twenty second Purge Delay the fan/heater unit(s) will
ignite. When the Plenum Temperature reaches the
Cycle Setpoint the fan/heater unit(s) will cycle to
Low-Fire. When the Plenum Temperature falls ten
degrees below the Cycle Setpoint the fan/heater unit(s)
will cycle back to High-Fire. The fan/heater units will
continue to cycle throughout the drying process.
When grain reaches the Chamber High Level
Rotary Switch the Fill 2 Delay will begin to count
down. When the Fill 2 Delay reaches zero Fill System
#2 will shut off and the Fill 1 Delay will begin to count
down. When the Fill 1 Delay reaches zero Fill System
#1 will shut off.
If the Chamber High Level Rotary Switch
becomes exposed due to shrinkage of grain in the
Drying Chamber, the fill system(s) will start and refill
the Drying Chamber. When grain reaches the Chamber
High Level Rotary Switch the fill system(s) will shut
off after the delays.
When the Dry Timer reaches zero and the
Grain Temperature Setpoint is above the current grain
temperature the dryer will go into Temperature Hold.
When the grain temperature reaches the Grain Temperature Setpoint the unit will continue to the Dump
Cycle. In the Dump Cycle the Linear Actuator in the
Actuator Control Box extends, the dump chutes lower,
and grain is dumped from the Drying Chamber into the
Storage Chamber. Immediately after the dump chutes
open the Dump Timer begins to count down. When the
Dump Timer reaches zero the dump chutes raise and
grain stops dumping from the Drying Chamber into the
Storage Chamber. During the Dump Cycle 1/3 of the
grain is dumped into the Storage Chamber.
After the Dump Cycle the unit returns to the
beginning of the Dry Cycle, the fill system(s) refill the
Drying Chamber and the process begins again. If the
Dry Timer reaches zero after the grain temperature
reaches the Grain Temperature Setpoint the unit does
not enter Temperature Hold. It goes right to the Dump
Cycle.
The unit continues with the same operation
until either no grain is present against the Wet Supply
Rotary Switch, or the Storage Chamber becomes full.

If the Wet Storage Tank becomes empty
while the fill systems are running, the Fill 1 and Fill 2
Delays starts to count down. When the Fill 1 and Fill 2
Delays reach zero the fill system(s) shut off along with
the dryer and a Wet Supply Hopper Empty “Out of
Grain” error is displayed on the Dryer Control Panel
screen. If there is grain against the Drying Chamber
Low Level Rotary Switch the unit can be restarted by
pressing the start switch. When the start switch is
pressed the screen on the Dryer Control Panel will read
“Press Enter to Dry Remaining Grain”. If the enter
button is pushed the dryer will restart without running
the fill system(s). The dryer will remain running until
the completion of the next Dump Cycle, after which an
“Out of Grain” error is displayed on the Dryer Control
Panel and the dryer stops.
START UP PROCEDURE
If the Storage Chamber High-Limit Rotary
Switch becomes covered with grain during the Dump
Cycle the dryer will continue through the Dump Cycle
and will continue to the next Dry Cycle. When the Dry
Cycle is complete the unit will not continue to the
Dump Cycle. A “Bin Grain Hi Limit” error will be
displayed on the screen and the dryer will stop. The
unit will not dump automatically until grain has been
removed from the Storage Chamber.
If the dryer stops for any reason the Aeration
Fan will remain running if the Aeration Fan Bypass is
enabled. The Aeration Fan Bypass is set in the Set-up
mode. If the Aeration Fan Bypass is disabled the
Aeration Fan stops whenever the dryer stops.
Start Up Procedure
At the beginning of each harvest and before
filling the dryer with grain make sure to inspect the
dryer for rodent damage, and system integrity. Enter
the drying chamber and check each dump hopper.
Remove any obstructions. Test operate the dryer using
the pre-season checklist.
There are two fundamental things to control
with the Autoflow Top Dry (or any dryer); the drying
rate and the grain flow rate. Drying rate is determined
by the dryer size and shape, the grain to be dried, the
airflow rate, and the drying air temperature. We
consider the best temperature to be the highest one
where the desired grain quality is maintained. Corn
used for livestock consumption is dried at a maximum
recommended temperature of 200 degrees Fahrenheit.
Corn used for different applications, and other grains
may require lower drying temperatures. By selecting a
drying air temperature a drying rate is established. To
achieve a desired final grain moisture content, the grain
flow rate is adjusted to match the drying rate.
