Pre-Season Checks
The following pre-season checks are intended to prepare your dryer for operation and bring any issues that may be present to your attention. Performing these check no later than 1-2 months before you intend to use the machine is recommended so that proper service can be performed and/or replacement parts can be ready before the harvest season begins.
Grain Fill & Discharge System
The following procedure will guide you through the grain fill and discharge system pre-season check. If the results of any of the following procedures are not consistent with what you should observe, service and/ or replacement parts may be required. Contact your dealer or refer to the Troubleshooting section of this manual for more information.
Turn all of the circuit breakers in the cabinet on. Turn the electric power supply to the dryer on.
On the Remote Control Cabinet, turn Power On through one of the HMI's by pressing the Control Power TURN ON button on the Controls page. The button should read ON and be illuminated green with a surrounding glow.
On the same Controls page, press the Takeaway START button. For level auger equipped dryers, pressing Takeaway START button should make the level auger start immediately.
On the same Controls page, press the Discharge START button. For profile style dryers, the discharge auger or conveyor (if equipped) should start immediately.
On the same Controls page, press the Metering START button. The metering rolls for profile dyers and the sweep arms for tower dryers should start turning.
Belt Adjustment
All belts will eventually seat themselves in the pulley grooves and the tension may have to be re-adjusted. If the belts squeal when the motor starts, they are not tight enough. Never apply belt dressing as this will damage the belt and cause early belt failure.
Discharge Auger Belt
To adjust the belt tension on the discharge auger, if equipped, loosen the unload auger motor mounting locknuts. Turn the locknut on the J-bolt to adjust the tension.
Level Auger Belt
Adjust the belt tension for the level auger, if equipped, by loosening the locknuts and raising the motor mount plate evenly with the four adjusting nuts, and then tighten the locknuts
Fans & Burners
The following procedure will guide you through the fan and burner system pre-season check. Perform this procedure for all fans and burners installed on the machine. If the results of any of the following procedures are not consistent with what you should observe, service and/or replacement parts may be required. Contact your dealer or refer to the Troubleshooting section of this manual for more information.
Turn the electric power supply to the dryer off.
Close the burner gas manifold hand valve for each burner (handle 90° relative to the piping).
In order to test the burners without grain in the dryer, the air pressure switches will need to be jumpered. To do this, place a jumper between terminal 343 (power) and 912 (air pressure switch 1) to jumper air pressure switch 1. If equipped with additional air pressure switches, place the jumper between 343 and the following terminals respectively: 922, 932, 942, 952, 962, 972 and finally, 982 in order to jumper air pressure switches 2 through 8.
This is only a temporary procedure for checking the burner. Under normal operation, never operate the dryer with the air pressure switches disconnected or bypassed. This safety air pressure switch is for your protection and the protection of the dryer.
Open all manual gas supply valves so that fuel is free to flow to the burner once the gas valves controlled by the ignition system are opened.
Turn the electric power supply to the dryer on.
On the Remote Control Cabinet, turn Power On through one of the HMI's by pressing the Control Power TURN ON button on the Controls page. The button should read ON and be illuminated green with a surrounding glow.
On the same Controls page, press the Fan START button. The Fan should start immediately and the air pressure light should illuminate.
Open the manual gas valve 1/4 of the way open to control the fuel flow to the burner once it has been lit
On the same Controls page, press the Burner START button. The burner should go through it's sequence and light.
Let the burner run for at least two minutes to verify that it is properly operating.
