5. Dryer Pre-Start Checks
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’s power panel.
Control Power Switch
Turn the CONTROL POWER switch to ON. The switch light comes on. “GSI” and the software version will appear. At this point, the controller will lock out all other dryer functions and the dryer will perform its safety circuit check. If a fault is found, the cause will be displayed on the LCD. If all safeties are found safe, the controller will supply power to the electronic fuel shut off valve (if so equipped). Press the start button to initialize the computer.
Power Start Button
Push the dryer start button, and all the toggle switches on the control panel will be activated. This initializes the load, fan, burner, unload and metering rolls individually.
Fuel Check
If using LP gas, make sure the tank has plenty of fuel and that the TANK DOES NOT HAVE A PRESSURE REGULATOR MOUNTED TO IT. 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 electronic shut off valve (Asco valve), if so equipped, or open the manual shut off valve on the dryer to allow fuel flow to the dryer. Inspect all gas lines and connections for possible leaks. ANY GAS LEAKS NEED TO BE FIXED IMMEDIATELY.
Load Auger
With the grain supply shut off, quickly bump the load auger switch to MANUAL and see if the load auger rotates clockwise, as viewed from the drive end, or counterclockwise if the dryer is a front load model. If the wet grain supply auxiliary is wired to the dryer it should also rotate in the correct direction at this time. Turn the load auger switch to the AUTO position. The top auger and wet grain supply auxiliary should run for one minute and then the dryer will shut down leaving the safety shut down message (out of grain) displayed. Press the dryer power stop button to reset the panel, then press the start button to resume operation.
1 Speed Operation
To check 1 Speed operation, place the unload switch in the 1 Speed setting. Turn the high speed metering roll dial up until the metering rolls start rotating. The bottom auger should rotate counterclockwise, as viewed from the drive end. The metering roll drive motor should rotate clockwise, as viewed from the drive end of the gear box. If the dry grain take away auxiliary is wired to the dryer, it should start and rotate in the proper direction.
