DRYER START UP
CONTINUOUS FLOW AND CONTINUOUS BATCH START UP PROCEDURE
At the beginning of each harvest and before filling the dryer with grain make sure to inspect the dryer for rodent damage, proper belt and chain tension and missing or dam- aged safety shields. Test operate the dryer using the prestart check procedures located on pages
1.Before attempting to operate the dryer make sure that all safety shields are in place, all plenum bottom closure panel doors are closed, all rear access doors are closed and all personnel are clear of the grain dryer and grain handling machinery.
2.Turn all selector switches on the control panel to the off position.
3.Turn on the electric power sup- ply to the dryer, and move the safety disconnect handle mounted on the dryer's upper power box to on.
4.Turn the control power switch to on. The switch will light up. A copyright message, model num- ber, total running time in hours and minutes, current date and time will appear. At this point the controller will lock out all other dryer functions. Once the date and time appear, press reset, and the dryer will perform its safety circuit checks. If a fault is found the cause will be dis- played on the LCD. If all are found safe the controller will
allow the electronic fuel shutoff valve to be manually opened (if so equipped), and the dry- ing mode switch will light up, indicating that the dryer is ready to be started.
5.Move the load auger switch to manual, and push the dryer power start switch. The top au- ger will immediately start, and the load auger switch will light up. If additional grain handling equipment is wired to the dryer it will also start immediately.
6.When the dryer is full of grain the top auger will stop automatically, and any grain handling equipment wired to the dryer will also stop.
CONTINUOUS FLOW
OPERATION
1.Turn the control power switch to on.
2.After the date and time appear on screen, press the reset button.
3.Push the dryer power start switch.
4.Open the main fuel supply valve on the tank if using LP gas, or open the fuel supply line if us- ing natural gas. Turn on the Maxon electric shut off valve, if soequipped,oropenthemanual shut off valve to allow fuel flow to the dryer.
5.Turn the drying mode switch to continuous flow.
6.The dryer should already be filled with grain. Turn the load auger switch to the auto posi- tion. In both the auto and manual positions the dryer grain level switch will automatically keep the dryer full of grain. In the auto position the dryer will shut down after a preset time period on the out of grain timer.
7.Turn the fan switch to on. The fan will start, and the switch will light up when airflow is detected.
8.Start the burner by turning the heater switch to on. After purg- ing for approximately 10 sec- onds the burner will fire, and the heater switch will light up. This indicates that the flame sensing circuit is sensing burner flame. For information concerning burner adjustment see the pre start section of this manual.
9.Operate the heaters to dry grain for
toberemovedwiththeplenumtem- perature set at 180°F. Example:
Shelled corn starts with 25% mois- ture and the final moisture content is to be 15% (10% removal). Us- ing the all heat dryeration process, the estimated drying time is 60 min- utes (10 x 6).
10.While operating the dryer adjust the metering roll dials to the recom- mended settings. See the charts on page 19 and 20.
