PNEG-1820 CE Compliant Top Dry Series 2000 Autoflow 31
During the dump cycle 1/3 of the grain is dumped into the storage chamber.
After the dump cycle, the unit returns to the beginning of the dry cycle, the fill system(s) refill the drying
chamber and the process begins again.
The unit continues with the same operation until either no grain is present against the Wet Supply Rotary
switch or the storage chamber becomes full.
If the wet storage tank becomes empty, the fill #1 and fill #2 delays starts to count down.
When the delays reach zero, the fill system(s) and dryer shut off.
Wet supply hopper empty “out of grain” error is displayed. If there is grain above the Drying Chamber Low
Level switch, the unit can be re-started by pressing the Start switch.
When the Start switch is pressed, the screen on the dryer control panel will read “press enter to dry
remaining grain”. If the Enter button is pushed the dryer will re-start without running the fill system(s). The
dryer will remain running until the completion of the next dump cycle, after which an “out of grain” error is
displayed on the dryer control panel and the dryer stops.
If the storage chamber reaches full during the dump cycle, the dryer will continue through the dump cycle
and will continue to the next dry cycle.
When the dry cycle is complete, the unit will not continue to the dump cycle. A “bin grain high-limit” error
will be displayed on the screen and the dryer will stop.
If the dryer stops for any reason, the aeration fan will remain running if the aeration fan bypass is enabled.
