6. Dryer Start-Up

10.After purging for approximately 10 seconds the heater will fire. For information concerning heater adjustment, see Dryer Pre-Start Checks on Page 22.

11.If the dryer is being operated in all heat, move the FAN switch to the ON position. In this position, the fan will run continuously during the dry, cool and unload stages of the staged batch operation. If the dryer is being operated in the dry and cool mode, the preferred position for the FAN switch is the ON position, so the fan will run continuously and continue to cool the grain during the unload operation. If desired, the fan can be turned OFF during the unload cycle of the dry-cool-unload sequence by turning the FAN switch to AUTO.

12.If the dryer is being operated in all heat, move the HEATER switch to ON. The burner will operate whenever the fan is operating. If the dryer is being used in dry and cool, turn the HEATER switch to AUTO and the burner will automatically shut down during the cooling and unloading cycles.

13.The bottom auger and metering rolls will start automatically during the unload cycle of the dry-cool-unload mode, along with any grain handling equipment that is wired to the dryer. The speed at which the metering rolls operate during the unload cycle is adjusted by using the high speed metering roll knob. Turning the dial clockwise will increase the grain discharge rate, and turning it counterclockwise will decrease the discharge rate.

14.When the last batch is done and the dryer is out of grain, turn the drying mode switch to continuous. Turn the load, unload, fan/heater switches off and push the dryer power start switch to arm the safety circuit. Run the fan/heater manually for 6 minutes per point of moisture to be removed. Turn the burner off to cool the grain for 30 minutes. Turn off the fan and manually unload the dryer by turning the unload switch to 1 Speed and setting the meter rolls as fast as the unload equipment will allow.

15.To control the length of the dry cycle using only the dry time setting programmed into the system, turn the MOISTURE CONTROL setting to OFF. To use the automatic moisture control so that the dry time is determined, not only by the dry time setting, but also by the moisture content of the drying grain, turn the MOISTURE CONTROL switch to ON.

16.To shut down the dryer, close the fuel supply valve at the fuel tank or fuel source. If the burner is operating, let the dryer run out of fuel, causing an automatic shut down due to a loss of flame. Close the fuel valve at the dryer, and press the dryer power stop button. Turn OFF the dryer’s main circuit breaker located on the front of the power panel. Turn OFF the main power supply to the dryer.

17.In case of an emergency, press the dryer power stop button. The burner, fan and all augers will stop immediately.
