Grain Systems PNEG-1820 - Manual (Page 33)

13. Start-Up Procedure
PNEG-1820 CE Compliant Top Dry Series 2000 Autoflow 33
12. Set the grain temperature set point as follows:
• 82°C Drying temperature = 38°C Grain temperature set point
• 77°C Drying temperature = 39°C Grain temperature set point
• 71°C Drying temperature = 41°C Grain temperature set point
• 66°C Drying temperature = 42°C Grain temperature set point
• * 60°C Drying temperature = 43°C Grain temperature set point
• * 54°C Drying temperature = 45°C Grain temperature set point
• * 49°C Drying temperature = 46°C Grain temperature set point
* When drying at a temperature lower than 66°C the grain temperature set point on the moisture
control thermostat may require a lower setting at right.
13. Press the Start switch on the dryer control panel.
14. The fill system(s) should start immediately.
15. When the grain reaches the Drying Chamber Low Level switch, the fan and heater(s) should start.
16. When the grain reaches the drying chamber, Low Level Rotary switch reaches the Drying Chamber
High Level Rotary switch the fill system(s) should stop.
17. When the dry timer reaches zero, the display should read “TEMP HOLD”.
18. When the grain temperature reaches the grain temperature set point, the dryer should continue to
the dump cycle.
19. The dump chutes should lower, grain should dump from the drying chamber into the storage chamber
and the fill system(s) should start.
20. After the dump cycle, the dryer should continue to the beginning of the next dry cycle.
21. After the fourth dump, stop the dryer.
22. Test the moisture of the dried grain.
23. If the moisture of the grain is too high, increase the grain temperature set point 2.5°C for each
additional point of moisture to be removed.
24. If the moisture of the grain is too low, decrease the grain temperature set point 2.5°C for each
additional point of moisture to be added.
25. After the moisture control thermostat is adjusted, decrease the time on the dry timer by one-half.
The dry timer should not be set lower than the amount of time it takes the dryer to refill after the
dump cycle.
26. Re-start the dryer. The time on the dry timer should expire before the grain reaches the
temperature set point.
27. Any time a change is made to the grain temperature set point, the dryer must dump four (4) times
before the full effect of the change will be made on the moisture of the grain.
CAUTION
Be sure all personnel are clear of fill systems. Place the Load Auger switch on the
dryer control panel to the “AUTO” position.
