SAFETY
Series 2000 Top Dry Heater Control
Heater Operation
Thank you for choosing a GSI product. It is designed to give excellent performance and service
for many years.
This manual describes the operation of the
Series 2000 Top Dry Heater Control Unit. Different models are offered, including a 36" diameter and a 42" diameter, with a choice of horsepower available on the fan motor.
The principal concern of the GSI Group, Inc.
("GSI") is your safety and the safety of others associated with grain handling equipment. This manual
is written to help you understand safe operating procedures, and some of the problems that may be encountered by the operator or other personnel.
As owner and/or operator, it is your respons-
ibility to know what requirements, hazards and
precautions exist, and to inform all personnel associated with the equipment, or who are in the
heater area. Avoid any alterations to the equipment. Such alterations may produce a very dangerous situation, where serious injury or death
may occur.
Roof Damage Warning
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.

The GSI Group, Inc. recommends
contacting your local power company,
and having a representative survey your
installation so the wiring is compatible
with their system, and adequate power
is supplied to your unit.
Safety decals should be read and
understood by all people in the grain
handling area. The bottom right decal should be present on the inside
bin door cover of the two ring door,
24" porthole door cover and the roof
manway cover.

OPERATING PROCEDURE
The control panel of the Top Dry heater unit.
Series 2000 Top Dry Heater Control
Setup And Configuration
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 necessary. Running fan/heater in this mode requires
climbing up to fan/heater to start unit and adjust controls.
2. Econo control center. In this case the control is
located up on the fan/heater and has been pre-programmed. Power is then applied from a switch below. 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 conditions will shut the dryer down but cannot be viewed
unless you climb up and look at the display.
Power Up
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 airflow switch. The air switch error on power up cannot be bypassed since, in the Top Dry system, the
fan is controlled by the heater control.
If multiple heaters are tied together, and the
master detects that the slaves fan is on (the air switch
stuck?), the master will lock up displaying "SLA
ERROR".
3. Manual control center. In this case the master
control is up on top where all the sensors and limits
are attached. The remote display below is attached
via a serial 2 wire link. The remote display is used
to program the master, view errors and start the
dryer. In essence, the remote display is just a slave
extension of the master.

Normal Operating Displays
Heater Not Running
The main display shows either dry 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"
switch (fan bypass) is used to select the mode to be
Page 6

OPERATING PROCEDURE
displayed. Note, that the cursors don't flash when
in the normal display. They do flash when in the
program mode.
The dry and cool time shown on the display is
"AIRFLOW" or "NO AIRFLOW" is displayed
if air is flowing or not flowing. "RX TX" is displayed 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
turned on again (see section on "Running the
Dryer" page 18, for mode explanation).
Programming Top Dry Plenum
And Grain Temperatures
Depress the program temperature switch on either
the master or remote. The upper left cursor will be
flashing. Use the up and down arrow switches to
program the temperature.
This first temperature setting is the temperature
at which the entire burner shuts off--no flame. Depressing the program switch again will cause the
display to advance to setting the cycle temperature
(upper 2nd from left cursor flashing). This temperature setting is the temperature above which the
heater goes to low flame. Depressing the program
switch again will cause the display to advance to
thegrain temperature limit setting (upper 2nd
Setting the plenum hi limit on the control box.

Series 2000 Top Dry Heater Control
from right cursor flashing).
When the grain temperature
gets to this point (or dry timer
times down), the heater control
advances to the cool cycle. If
no cool time is programmed in, the
dryer shuts down
when the grain gets
to that temperature.
Depressing the
program switch
again will cause the
display to advance
to setting the differential temperature setting (upper
right cursor flashing). This differential is basically
hysteresis. When
main or cycle solenoids shut off due to exceeding the temperature
set point, that burner will not come on again until the temperature
falls below the set point minus temperature differential. Depressing the program switch again will cause the control to exit the program mode.
Programming Top Dry-
Dry And Cool Timers
Depressing the program dry and
cool times switch will cause the
lower left cursor to begin flashing, indicating a new dry time
may be entered. This dry time is
the length of time the heater will
run in the dry mode (burners controlling to the temperature set in
the above program mode). This
time can be set from 1.0 hours to
20.0 hours. Depressing the program dry and cool times switch
again will cause the lower 2nd
from left cursor to begin flashing.
Setting the dry time on the control box.
This is the cool period. When the burners get shut down due to the
dry timer timing out, or grain reaching temperature set point, the fan
will
continue to run cool. This cool time can be set from 0.0 hours to 20.0
hours. If set to 0.0 hours, there is no cool period. Depressing the
program dry and cool times switch again will cause the control to exit
the program mode.
Programming Top Dry Fan Delay For Slaves
Fan delay time is the amount of time in seconds between the fans
starting. Power up with the "Program Dry/Cool Timers" and " Program Temperatures" switches depressed to adjust the programmable
to adjust the programmable delay for Top Dry fans.
The dry time and cool time "carrots" on the display both flash
indicating it is in the program delay time mode.
Note: This can only be done on the master.

17. Press the "PROGRAM TEMPERATURE" button 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 TEMPERATURE" 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.
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 applicable.
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 Fan Without Burner
1. To run fan without burner press the down arrow
key then press the start key. This will start the fan
without running the burner. The fan will run
continuously until the toggle switch is shut off.
"LO-FLAME" part of the cycle (see "Programming Top
Dry Plenum And Grain Temperatures" page 15, for setting the HI/LO-FLAME temperature). If the temperature is above the high temperature setting, the flame will
be off, the "FLAME" message will be out and the display 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
shut down, and then the fan will shutdown. If a
limit opens or an error condition occurs during drying, 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 period. 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 program 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.
Running The Dryer
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
10
Run Hours Display

also.
4. Push "PROGRAM (DRY/COOL TIMES)" but
ton on the series 2000 control panel to enter program 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 moisture content (see drying rates chart page 20).
6. Push "PROGRAM (DRY/COOL TIMES)" button to continue to set the cool time. Arrow
should be above "COOL TIME".
7. Set cool time desired by using increase or decrease buttons.
8. Push "PROGRAM (DRY/COOL TIMES)" button 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 plenum high limit. High limit should be set 20 degrees 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 plenum cycle set point. This is the desired plenum
temperature for normal drying. Use the recommended plenum temperature for your grain type
and moisture content.
13. Press the "PROGRAM TEMPERATURES"
button to continue to set the "GRAIN TEMPERATURE SET POINT".
14. Use the increase or decrease buttons to set the
grain temperature set point. On the first batch
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.
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 current grain tempera ture.
22. When the dryer shuts down enter this grain temperature in place of the 140° grain temperature
set point entered earlier.
23. Dump batch.
24. After dumping the batch test the moisture content 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 desired, lower the dry time by 20% and repeat steps
18-23 again on next batch.
26. If the grain moisture content is higher than desired, increasedry time by 30% and repeat steps
18-23 again on next batch.
27. If the grain moisture content is within the desired 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 decrease buttons at the same time to reset.

ERROR CONDITIONS
Limit Switches
The following limit switch errors light up indi-
vidually on the heaters LCD screen:
PLENUM, HOUSING, VAPOR, TEMP HI
LIMIT
Multiple Heater Error Conditions
through the serial link. If the master cannot communicate with a slave controller, the master will display "SLA" on the main display and the "RX" "TX"
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 originates. The master displays "SLA ERROR".Two or more heaters may be connected together

Error 7 is
most likely
caused by stuck

by control.

Slave #1 inconsistent with master with either
the drying grain
flag or the LP
main solenoid or
cycle solenoidmost likely the
slave got reset
powering up with
the solenoids off
(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.
Slave #2
inconsistent
same as error 9
for slave #1
Slave #3
inconsistent
same as error 9
for slave #1
Airflow short
Wrong voltage.
Dip switch #5 is
the voltage selector switch. If
dip switch #5 in
"ON" that selects 240 VAC.
If the unit has
only 120 VAC
applied, error 12
will show up. If
dip switch #5
is"OFF" that selects 120 VAC. If
the unit has 240
VAC applied error 12 will show
up.
This is important 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 solenoids will have
240 VAC applied
to them which
will damage solenoids.
