Series 2000 Top Dry Heater Control

GSI cannot warrant any roof damages due to excessive

vacuum or internal pressure caused by fans or other air

moving systems. Adequate ventilation and/or "makeup

air" devices should be provided for all powered air han-

dling systems. GSI does not recommend the use of down-

ward flow systems (suction). Severe roof structural dam-

age can result from any blockage of air passages. Run-

ning of fans during certain high humidity/cold weather

conditions can cause freezing over of air exhaust or in-

take ports.

Series 2000 Top Dry Heater ControlOPERATING PROCEDURE

There are three possible configuration modes forthe Top Dry.1. Stand alone heater control. Master control islocated on fan/heater and no other control is neces-sary. Running fan/heater in this mode requiresclimbing up to fan/heater to start unit and adjust con-trols.

2. Econo control center. In this case the control islocated up on the fan/heater and has been pre-pro-grammed. Power is then applied from a switch be-low. The start switch is a momentary switch that isattached to J7-7 connector. The dryer is started bydepressing that momentary switch. Note, that in thismode, the display is remote, therefore error condi-tions will shut the dryer down but cannot be viewedunless you climb up and look at the display.

Limit switches are checked upon power up. Thecontrol checks all the limit switches. If a limit switchhas become open circuit the control displays whichlimit is open circuit. The control will not operatewith a limit switch error. The fan will not turn onwith an error condition. There is no way to bypassan error condition. It must be fixed (see errors page22). The air switch is also checked on power up.The air switch should indicate no airflow. This isneces-sary to check the function of the air-

This first temperature setting is the temperatureat which the entire burner shuts off--no flame. De-pressing the program switch again will cause thedisplay to advance to setting the cycle temperature(upper 2nd from left cursor flashing). This tem-perature setting is the temperature above which theheater goes to low flame.

"AIRFLOW" or "NO AIRFLOW" is displayedif air is flowing or not flowing. "RX TX" is dis-played if there is a master with remote.

The limits are continuously checked duringthe off mode. A limit switch open or any othererror condition will cause the display to show thelimit or error condition. When the dryer is notrunning, if the limit or error condition is corrected,the LCD returns to its normal display. This is notthe case with an error or limit condition duringthe drying operation. This causes the display tolock up in the error display mode, the dryerstops running, and the error must be corrected.The toggle switch must then be shut off and

The main display shows either dry run time(lower left cursor), cool down time (lower 2ndfrom left cursor), plenum (lower 2nd from rightcursor) or grain temperature (lower right cursor).The "mode select" (fan bypass) is used to selectthe mode to be displayed. Note, that the cursorsdo not flash when in the normal display. They doflash when in the program mode (see page 18).

The dry and cool down shown on the display isthe amount of time remaining in the dry or cool pe-riod. Note, that if unit is in the dry time period,you cannot view the cool time remaining, since theunit is not in the cool period. However, the coolperiod may be altered or viewed by entering the pro-gram mode. The same is true if the heater control isin the cool period. You cannot view the dry run time,since that time has already expired.

20. Increase the cycle set point to return to high flame.

21. Turn off fan/heater by placing the toggle switch inthe "OFF" position.

22. Repeat process on second fan/heater if appli-cable.

23. Watch heater run several minutes to make sureit cycles between hi and lo flame properly.

24. Hi-flame pressure should be adjusted so plenumreaches cycling temperature easily.

25. Lo-flame should be adjusted so temperaturedrops slowly, until switching back to high flame.

Running The DryerRun Hours Display

Run hours are recorded when the controller detectsthat the fan is on (airflow). The hours may be viewedby depressing the "HOURS" to get hours and"HOURS X 1000" to get the number of 1000 hoursaccumulated.

17. Press the "PROGRAM TEMPERATURE" but-ton to change the temperature set points. Press itagain to change the "CYCLE SET POINT".The display should read 160°.

18. Decrease the "CYCLE SETPOINT TEMPERA-TURE" until the heater cycles to low flame.

19. Open or close the low cycle ball valve until the gaspressure is 3-5 lbs. for LP, or 1-2 lbs. for natural gas.

The display will indicate "FLAME" when flame is sensed.If no flame is sensed the "FLAME" message will be off.The display indicates what part of the cycle it is in. Thedisplay will indicate whether it is in the "HI-FLAME" or

"LO-FLAME" part of the cycle (see "Programming TopDry Plenum And Grain Temperatures" page 15, for set-ting the HI/LO-FLAME temperature). If the tempera-ture is above the high temperature setting, the flame willbe off, the "FLAME" message will be out and the dis-play will be flashing "OFF-CYCLE".

The limits are continuously checked during thedrying operation. A limit switch open or any othererror condition will cause the dryer to

tion. If using a remote display or economy start,place that toggle switch to the "ON" positionalso.

4. Push "PROGRAM (DRY/COOL TIMES)" button on the series 2000 control panel to enter pro-gram mode. Arrow should be flashing at lowerleft side of screen above "DRY TIME".

5. Set dry time using increase or decrease buttonsas 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. Arrowshould 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" buttonto enter temperature programming mode. Arrowshould 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 temperaturewhen drying.

11. Press "PROGRAM TEMPERATURES" buttonto continue to set "PLENUM CYCLE SETPOINT".

12. Use the increase or decrease buttons to set ple-num cycle set point. This is the desired plenumtemperature for normal drying. Use the recom-mended plenum temperature for your grain typeand 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 thegrain temperature set point. On the first batch

20. Monitoring of the plenum, grain temperatures,dry time and cool times is possible by pressingthe mode select button to alternate betweenmodes.

21. Immediately after the burner shuts off and thedryer 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 temperatureset point entered earlier.

23. Dump batch.24. After dumping the batch test the moisture con-

tent of the grain. Average several samples. Whencomputing moisture content make allowancesfor cooling of the grain.

25. If the grain moisture content is lower than de-sired, lower the dry time by 20% and repeat steps18-23 again on next batch.

26. If the grain moisture content is higher than de-sired, increasedry time by 30% and repeat steps18-23 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 willturn off at the proper grain temperatureand 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 "TEMPERATUREDIFFERENTIAL".
