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 Control
OPERATING PROCEDURE
There are three possible configuration modes for
the Top Dry.
1. Stand alone heater control. Master control is
located on fan/heater and no other control is neces-
sary. Running fan/heater in this mode requires
climbing up to fan/heater to start unit and adjust con-
trols.
2. Econo control center. In this case the control is
located 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 is
attached to J7-7 connector. The dryer is started by
depressing that momentary switch. Note, that in this
mode, the display is remote, therefore error condi-
tions will shut the dryer down but cannot be viewed
unless you climb up and look at the display.
Limit switches are checked upon power up. The
control checks all the limit switches. If a limit switch
has become open circuit the control displays which
limit is open circuit. The control will not operate
with a limit switch error. The fan will not turn on
with an error condition. There is no way to bypass
an error condition. It must be fixed (see errors page
22). The air switch is also checked on power up.
The air switch should indicate no airflow. This is
neces-sary to check the function of the air-

not be bypassed since, in the Top Dry system, the
fan is controlled by the heater control.

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

"AIRFLOW" or "NO AIRFLOW" is displayed
if air is flowing or not flowing. "RX TX" is dis-
played if there is a master with remote.
The limits are continuously checked during
the off mode. A limit switch open or any other
error condition will cause the display to show the
limit or error condition. When the dryer is not
running, if the limit or error condition is corrected,
the LCD returns to its normal display. This is not
the case with an error or limit condition during
the drying operation. This causes the display to
lock up in the error display mode, the dryer
stops running, and the error must be corrected.
The toggle switch must then be shut off and

Depressing the program dry and
cool times switch will cause the
lower left cursor to begin flash-

trolling to the temperature set in
the above program mode). This
time can be set from 1.0 hours to
20.0 hours. Depressing the pro-
gram dry and cool times switch
again will cause the lower 2nd

OPERATING PROCEDURE
shut down, and then the fan will shutdown. If a
limit opens or an error condition occurs during dry-
ing, the control will lockup in the error display
mode. Power must be shut off and back on to clear
the error condition, even when the error or limit that
caused the shut down has been corrected.
The main display shows either dry run time
(lower left cursor), cool down time (lower 2nd
from left cursor), plenum (lower 2nd from right
cursor) or grain temperature (lower right cursor).
The "mode select" (fan bypass) is used to select
the mode to be displayed. Note, that the cursors
do not flash when in the normal display. They do
flash when in the program mode (see page 18).
The dry and cool down shown on the display is
the 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 the
unit is not in the cool period. However, the cool
period may be altered or viewed by entering the pro-
gram mode. The same is true if the heater control is
in 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 in
the "OFF" position.
22. Repeat process on second fan/heater if appli-
cable.
23. Watch heater run several minutes to make sure
it cycles between hi and lo flame properly.
24. Hi-flame pressure should be adjusted so plenum
reaches cycling temperature easily.
25. Lo-flame should be adjusted so temperature
drops slowly, until switching back to high flame.
Running The Dryer
Run Hours Display
Run hours are recorded when the controller detects
that the fan is on (airflow). The hours may be viewed
by depressing the "HOURS" to get hours and
"HOURS X 1000" to get the number of 1000 hours
accumulated.
17. Press the "PROGRAM TEMPERATURE" but-
ton to change the temperature set points. Press it
again 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 gas
pressure 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. The
display will indicate whether it is in the "HI-FLAME" or
"LO-FLAME" part of the cycle (see "Programming Top
Dry PlenumAnd Grain Temperatures" page 15, for set-
ting the HI/LO-FLAME temperature). If the tempera-
ture is above the high temperature setting, the flame will
be off, the "FLAME" message will be out and the dis-
play will be flashing "OFF-CYCLE".
The limits are continuously checked during the
drying operation. A limit switch open or any other
error condition will cause the dryer to

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

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°.

Series 2000 Top Dry Heater Control ERROR CONDITIONS
symbols will be flashing. If a limit switch error or
one of the error numbers 1 through 8 occurs, that
error is displayed on the slave where the error origi-
nates. The master displays "SLA ERROR".Two or more heaters may be connected together

Wrong voltage.
Dip switch #5 is
the voltage se-
lector switch. If
dip switch #5 in
"ON" that se-
lects 240 VAC.
If the unit has
only 120 VAC
applied, error 12
will show up. If
dip switch #5
is"OFF" that se-
lects 120 VAC. If
the unit has 240
VAC applied er-
ror 12 will show
up.
This is im-
portant because
if the fan heater
is set up at GSI
for 120 VAC and
the customer
connects to 240
VAC the heater
control will work,
but if allowed to
operate the so-
lenoids will have
240 VAC applied
to them which
will damage so-
lenoids.

MISC ERROR NUMBERS
The following limit switch errors light up indi-
vidually on the heaters LCD screen:
PLENUM, HOUSING, VAPOR, TEMP HI
LIMIT
(Errors 9 through 11 are displayed only if multiple heat-
ers are tied together through serial link).
Note: Temperature sensor connection-the temperature
sensor (bolt) must always be connected to the master.
In the case of the Top Dry, both temperature sensors
must be connected to the master (unit at the top). Top
Dry grain temperature input is connected to J7 pins 14
and 18.
through the serial link. If the master cannot com-
municate with a slave controller, the master will dis-
play "SLA" on the main display and the "RX" "TX"
