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 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
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.
bands are installed properly and in are good shape.
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.
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. If the dryer is empty, the unit will not oper-
ate. 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 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.
