Series 2000 Top Dry Heater Control
QUICK STAR T PROCEDURE
1. Raise chutes.
2. Fill drying chamber with grain.
3. Turn toggle switch at fan/heater to "ON" posi-
tion. If using a remote display or economy start,
place that toggle switch to the "ON" position
also.
4. Push "PROGRAM (DRY/COOL TIMES)" but
ton on the series 2000 control panel to enter pro-
gram mode. Arrow should be flashing at lower
left side of screen above "DRY TIME".
5. Set dry time using increase or decrease buttons
as recommended for your grain type and mois-
ture content (see drying rates chart page 20).
6. Push "PROGRAM (DRY/COOL TIMES)" but-
ton to continue to set the cool time. Arrow
should be above "COOL TIME".
7. Set cool time desired by using increase or de-
crease buttons.
8. Push "PROGRAM (DRY/COOL TIMES)" but-
ton to exit programming mode.
9. Push "PROGRAM TEMPERATURES" button
to enter temperature programming mode. Arrow
should be flashing at upper left of screen under
"PLENUM HIGH LIMIT SET POINT".
10. Use the increase or decrease buttons to set ple-
num high limit. High limit should be set 20 de-
grees higher than desired plenum temperature
when drying.
11. Press "PROGRAM TEMPERATURES" button
to continue to set "PLENUM CYCLE SET
POINT".
12. Use the increase or decrease buttons to set ple-
num cycle set point. This is the desired plenum
temperature for normal drying. Use the recom-
mended plenum temperature for your grain type
and moisture content.
13. Press the "PROGRAM TEMPERATURES"
button to continue to set the "GRAIN TEM-
PERATURE SET POINT".
14. Use the increase or decrease buttons to set the
grain temperature set point. On the first batch
20. Monitoring of the plenum, grain temperatures,
dry time and cool times is possible by pressing
the mode select button to alternate between
modes.
21. Immediately after the burner shuts off and the
dryer is in the cool cycle, take note of the cur-
rent grain tempera ture.
22. When the dryer shuts down enter this grain tem-
perature in place of the 140° grain temperature
set point entered earlier.
23. Dump batch.
24. After dumping the batch test the moisture con-
tent of the grain. Average several samples. When
computing moisture content make allowances
for cooling of the grain.
25. If the grain moisture content is lower than de-
sired, lower the dry time by 20% and repeat steps
18-23 again on next batch.
26. If the grain moisture content is higher than de-
sired, increasedry time by 30% and repeat steps
18-23 again on next batch.
27. If the grain moisture content is within the de-
sired range, increase the dry time by 20% on
the next batch. This insures that the burner will
turn off at the proper grain temperature
and allows for a wetter batch.
28. After changing times press the increase and de-
crease buttons at the same time to reset.
the set point should be 140°.
15. Press the "PROGRAM TEMPERATURES"
button to continue to set the "TEMPERATURE
DIFFERENTIAL".
16. Use the increase or decrease buttons to set the
temperature differential. The recommended set
point is 10°.
17. Press the "PROGRAM TEMPERATURES"
button to exit the program mode.
18. Press the increase and decrease buttons at the
same time to reset current settings.
19. Once all times and temperatures have been set
press the start button to begin drying.
