Dryer Checks
This section gives a series of checks to be carried out on the dryer before starting for the first time in the
drying season. If any of the checks fail to produce the stated result, you should consult your dealer.
You should not attempt to use the dryer unless all the pre-start checks have been successfully completed.
Inspect the Accutrol Metering System
Open the four (4) access doors and inspect the accutrol sweep metering system to ensure that the
system is free of foreign material.
Electrical Power
Turn ON the electrical power supply to the dryer, set all circuit breakers to ON, including the safety
disconnect handle mounted on front of the dryer power panel.
Control Power Switch
Turn the Control Power switch to ON. At this point the controller will lock out all other dryer functions.
Once the Boot screen appears
(See Page 24) , touch the Start Dryer button and the dryer will perform a
safety circuit check. If a fault is found, the cause will be displayed on the Main screen. If all are found
safe, the Start switch will illuminate, indicating that the dryer is ready to be started.
Start Switch
Push the Dryer Start switch, and all the selector switches on the control panel will be activated.
Fuel Check
If using LP gas, make sure the tank has plenty of fuel and that the tank does not have a regulator
mounted on the liquid line. Slowly open the main fuel supply valve at the tank. Then, open the manual
shut off valve on the dryer to allow fuel flow to the dryer.
If using natural gas, make sure an adequate supply at 10 PSI of pressure is available. Turn ON the valve
along the supply line. Inspect all gas lines and connections for possible leaks.
Load Auger
With the grain supply shut off, quickly bump the Load Auger switch to manual, and check all filling
equipment for proper rotation.
Turn the Load Auger switch to the AUTO position. The filling equipment should run for eight (8) minutes
(the default out of grain setting) and then the dryer will shut down leaving the safety shut down message
(out of grain warning) displayed. Press the Dryer Power Stop button to reset the panel, then press the
Start button.
Before attempting to operate the dryer make sure all safety shields are in place,
all access doors are closed and all personnel are clear of the dryer.
Any gas leaks must be fixed immediately.
