Autoflow Operation
tape measure to measure the stroke on the linear
actuator. The stroke should be between 12” and
14”. If the stroke on the actuator is not 12” to 14”,
the actuator should be adjusted. Make sure that all
pulleys and cables are able to move freely when
the actuator is moving. With the actuator ex-
tended, 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 com-
pletely, the double nuts on the bolt that the chutes
hinge on, needs 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.
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
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 connec-
tions for possible leaks. Any gas leaks need to be
fixed immediately!
Fan
Make sure that the fan and heater service
switches on the main drying fan(s) are in the “on”
position. 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. If the
dryer is empty, the unit will not operate. The fans
cannot create enough static pressure to engage the
airswitch. You will receive a loss of airflow
message.
Aeration Fan
Bump the aeration fan switch on the
autoflow control box and observe the aeration fan
rotation. The aeration fan should run counter-
clockwise. 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
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
