READ THESE INSTRUCTIONS
BEFORE OPERA TION AND SER VICE
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before trying to operate the dryer.
2. Power supply should be OFF for service of electrical components. Use CAUTION in checking voltage or other procedures requiring power to be ON.
3. Check for gas leaks at all gas pipe connections. If any leaks are de­tected, do not operate the dryer. Shut down and repair before further operation.
4. Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on the unit.
5. Set pressure regulator to avoid excessive gas pressure applied to burner during ignition and when burner is in operation. Do not exceed maxi-
mum recommended drying temperature.
6. Keep the dryer clean. Do not allow fine material to accumulate in the plenum or drying chamber.
Use Caution in the
Operation of this
Equipment
The design and manufacture of this dryer is directed toward operator safety. However, the very nature of a grain dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, does present a hazard to personnel, which can not be completely safeguarded against, without interfering with ef­ficient operation and reasonable ac­cess to components. Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary convey­ors, which may start without warn­ing when the dryer is operating on automatic control.
7. Use CAUTION in working around high speed fans, gas burners, augers and auxiliary conveyors which START AUTOMATICALLY.
8. Do not operate in any area where combustible material will be drawn into the fan.
9. Before attempting to remove and reinstall any propellor, make certain to read the recommended procedure listed within the servicing section of the manual.
10. Clean grain is easier to dry . Fine material increases resistance to airflow and requires removal of extra moisture.
This product is intended for the use of grain handling only. Any other use is considered a misuse of the product. Some edges of the product components can be sharp. It is recom­mended that each component of this product be examined to deter­mine if there are any safety considerations to be taken. Any and all necessary personal protective equipment should be worn at all tines when handling, assembling, installing and operation of the product and/or components. Guards are removed for illustration purpose only. All guardsmust be
KEEP THE DRYER CLEAN
DO NOT ALLOW FINE
MATERIAL TO ACCUMULATE
IN THE PLENUM CHAMBER
OR SURROUNDING THE OUT-
SIDE OF THE DRYER
Continued safe, dependable opera­tion of automatic equipment de­pends, to a great degree, upon the owner. For a safe and dependable drying system, follow the recommen­dations within this manual, and make it a practice to regularly inspect the operation of the unit for any devel­oping problems or unsafe conditions. Take special note of the safety pre­cautions listed above before attempt­ing to operate the dryer.

OTE: This Version does NOT support Wat chdog and the Heater Version MUST be 1.09. HEATER VERS – 1.09 IO
VERS – 1.07
1) The "FAN DELAY" is now called "MOTOR DELAY".
2) Added a way for GSI to reset total hours.
3) Here is a list of switches/features which can be found under the setup screens accessed via holding in on MODIFY whil e
owering on the Control Power.
Below is a description for each defin in g w hat it means t o disable/enable them : i)
AIRSWITCH
requirements for the burner regardless of the actual air switch state. ii)
LOW LE VEL SWITCH
state of the rotary swi tc h. When disabl ed the dryer will think the l ow level switch is always covered. iii)
WET TANK SWITCH
always covered w it h grain. iv)
START FANS WITH
Disabled means dryer will start according to drying chamber low level switch. v)
AERATION FAN BYPASS
dryer shutdow n.
4) The REFILL TIM ER and the TIME UNTIL LOAD OFF screens are only shown w hen t he dr yer is set for Autobat c h mode.
5) There are two more settings available under the "Power on and Modify key in" se quence for the user to set how many de gr ees a
measured temperature can exceed a set poi nt w ithout causing an overheat. The user can set 10 -> 50 degrees above the setpo in t to be an overheat conditi on. The default for the plenum
temp is 20F and the default for the grain temp is 30F.
6) The low level rotary switch function is the same as it was in 2.14, but now instead of giving a warning which states "DRY
CHAMBER EMPTY " whe n
it become s un c overed it gives "LOW LEVE L SW EXPOSED ."
7) Added an Out of Grain Timer. The time value can be changed under the setup but ton. This timer starts whenever either fill
systems is running and the load switch is in the auto position. The timer is reset when both load augers stop. If the timer runs out of time an OUT OF GRAIN
warning is issued. The
default is 20 minutes. Any time the value of this Timer is change d th e new val ue takes effect immediately.
8) Changed warning for wet bin empty to state "WET BIN SW EXPOSED" instead of saying “DRYER OUT OF GRAIN”.
9) Renamed "FILL 1 DE LAY" to "FIL L SY S TE M #1 ". Changed name of "FILL 2 DELAY" to "HI LEVEL SW". The HI
LEVEL SW delay is always available on both one and two fill sys t em dr yers and is used to make sure the dryer is full s o you don't get bogus shu t downs. The FILL SYSTE M #1 delay is only available when you are set for two fill systems and it is use d to es ta blish auger cleanout time.
10) If the Storage Bin Hig h Lim i t is det ected as failed (the N.C. pin and the N.O. pin from the swit ch are both reporting the sam e
voltage, 0 or 12 volts) a warning is reported as “BIN HI LIMIT SW BAD”.
11) If wet supply rotar y switch becomes unco ver e d t her e i s a tim er w hi ch m us t expire before a warni ng is given. This timer/delay
was called "AUX 1 DELAY", but is now termed "WET BIN SW. delay" It is found under t he DELAYS key.
12) The time a user has to think about making a chang e to a timer/setpoint bef or e i t au tomatically proceeds to the next selection
screen has been doubled.
13) Changed the name of de lay/timer "LOW LEVEL TIMER" to "LO L EVEL SWITCH."
14) Enabled the "START FANS WITH HIGH" switch function. There was previously a screen available to select this function, but
it was never active.
15) The cool down timer is now set to the reload valu e of the cool timer whenever any one of the four foll ow i ng s hutdowns takes lace:
i) Dry and Hold swit c h i s turned to on state. ii) Grain falls awa y from wet bin supply switch. iii) Storage chamber is full. iv) Dryer is o ut of gr ain.
16) Fans Off Delay now defaults to 0 minutes i nstead of 1 minute and has an upper limit of 5 minutes. This delay can be f ound
under the “delay” key.
17) The dryer functions the same whether the l oad s w i tch is in auto or on, but the o ut of gr ai n timer only times dow n while the load
switch is in the auto position and one of the load a ugers i s run ni ng. ********************************************************************* VERSION: 2.14 REVISED BY: Steve Logue RELEASE DATE: Sept 20, 2002

1) Burner differential would not stay at 1 deg F w hen the dryer was tur n of f , usi ng 2.10, now it does.
2) When grain reaches the St or age Chamber Rotary Switch, the dryer will enter a "Cool Down Mode". The fan will run and coo l thegrain for 10 minutes before shutting dow n due to a Storage Cham ber Full error.
3) When grain falls away from the Wet Supply Rot a ry Switch, th e dryer will ente r a "Cool Down Mode" after the fill syst em shut off. The fan will run and cool the grai n f or 10 minutes before shut t i ng down due to a No Wet Supply error.
4) When the Dry & Hold switch is placed in the "On" position the dryer will enter a "C ool D ow n Mode" for 20 minutes bef ore stopping. This only happens at the end of the dry cycle.
5) Corrected a problem with t he Fans Off Delay. If there is tim e on this delay, the fans and heaters will shut off duri ng the unload cycle, after the unl oad cycle is complete the delay counts down. The fans and heaters will not start again until the delay has reached zero.
6) Corrected a problem with the Time Until Load Off percentage set in the set-up mode. Now, in Auto batch only, the Fill Systems will shut off if grain has not reached th e dr y chamber high level rotar y s w i tch within the set perce nta ge of the dry timer is comple te d. Example: 1 hr dry time, 50% Time Until Load off. The fill systems w i ll shut off regardles s of ro tary switch status aft er 30min has expired.
7) Corrected a problem with t he Refill Delay. Now, i n Au t o bat ch O nly. The Refill Delay begins to count down af ter t he unload cycle is completed. If grai n has not reached t he dr yi ng chamber low level rot ary sw i tch before this delay reac hes zer o, a dr y chamber empty error is gi ven.
********************************************************************* VERSION: 2.10 REVISED BY: Steve Logue RELEASE DATE: Sept 11, 2000
1) Changed the Minimum Burner Differential t o 1 Deg Fahrenheit
2) Fixed the problem wh er e th e bur ner w as not shutting off whe n th e Dry & Hold switch was pla ced i n t he "O n" position, the Dry
Cycle was complete, and the Dryer was in the Cool Cycle. Now, when the Dry & Hol d swit ch i s pla ced i n t he "O n" position, and the Dry Cycle is complete, the dryer will shut th e bur ner off and will cool for the amount of ti m e on t he C ool Timer before sto ppi ng.
3) Fixed a problem wher e the dr yer w as not shutting down wit h an "O ut of Grain" error when the Wet Supply Ro t ar y Sw i tch was exposed. Now whe n th e Wet Supply R otary Switch is exposed, the Fill #1, and Fill #2 delay will count down and shut off Fill System #1 & #2, then the dryer will shut down with an "Out of Grain" er r or. If there is still grain aga inst the Low Level Rotary Switch, the dryer can be rest ar t ed by pr ess i ng the Stop switch to clear the error, turning the Load Auger switch to the "Off" pos i t i on, and pressing the Star t switch. When the Star t swi tch is pressed the screen will say "Press <Enter> to Dry Remaining Grain". If the <enter> button is pressed the dryer will restart. NOTE: If the Load Auger switch is left in the "Auto"
osition an "Out of Grain" error will be gi ven on startup. ********************************************************************* VERSION: 2.09 REVISED BY: Steve Logue RELEASE DATE: May 15, 2000

********************************************************************* VERSION: 2.01 REVISED BY: Steve Logue RELEASE DATE: October 4, 1999
1) Attempted to fix the pr oblem of grain setpo in t ch anging by itself.
2) Fixed problem of batch dry e r always shutting down with a "DRYING CHAMBER EMPTY" war ni ng. A delay called the "RE FILL TIMER" allows the dryer to fill back up.
********************************************************************* VERSION: 2.00 REVISED BY: Jeff Falconer RELEASE DATE: January 6, 1999
1) Fixed hour timer so dryer w i ll now show running time of dr yer .
2) Changed the way the dryer s hut dow n when using the dry and hold switch, now it will cool the grain usin g the cool timer before it s hut s down to prevent hea t
buildup of grain past the grain temp set points thereby causing a shutdown condition. Works in Autoflow and AutoBatch modes.
3) Fixed the clock to properly roll over in the year 2000.
4) Added a user batch coun t an d us er tim er i ndependent from th e Total batch and Total tim e all ow i ng monitoring of di f f e r ent us er s dr ying grain or diff er ent fields for compar ison of drying time.
5) Added a test procedure for the keypad. Turning all of the control switch es t o th e right (on position) and holding in the stop switch while turning on the
control power acti vates it. User can now test each individual keypad switc h f or m alfunction or stuck keys. (Taken out in 2.03)
6) Added control switc h testing by pressing and hold the plenum and gr ain switches in while t ur ni ng on the control power. Thi s w ill allow the user to test for
failed switches or computer failure to detect switch positi on changes. (Changed in 2.03 to turn power on w ith H elp key depressed)
7) Removed garbage displayed when user selected to view total runni ng time and total batches.
8) Added a check to make sure the dump switch is always i n th e A ut o pos i stion. Otherwise if left in manual close will caus e th e dryer never to dump.
9) Fixed several bugs t hat were reported to use by users and dealers.
10) I added the ability to reset the Total Dryer running time by pressing the HOUR and RESET button together and turn on the dryer.
11) Removed watchdog option in Extended setup mode sin ce w a t chdog has not been impl em ented yet.
12) Changed the wording to some of the error messages concerning th e ro tary switches to help eliminate some confusion of which switch was at fault.
13) Moisture contr ol light w ill now flash to give a visual indication that t he dr yer is in temperature hold.

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 heaters are tied together through serial link).
Note: Temperature sensor connection-the temperature sen- sor (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 V AC applied, error 12 will show up. If dip switch #5 is"OFF" that se­lects 120 VAC. If the unit has 240 V AC 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.

Error Details
Error #1 Plenum T emperature Probe Open. The two wires for checking this error are on terminals 24 and 25 they are labeled J7-12 and J7-13. The wires must be removed from the terminals to receive a correct reading. This must be checked with a Ohm Meter . If the probe is open you will not receive any reading on your meter because there is no continuity between the wires. It is like you cut the wire in half. If there is resistance there is a certain resistance reading for current temperature of the probe. See Chart at the back of this section to verify that the sensor is correct. If the sensor is correct you probably did not have a good connection from one of your wires to the terminal strip.
Error #2 Plenum T emperature Probe Short. This error is indicating that the Plenum T emperature probe is shorted. This will also need to be check with a Ohm meter and if it is shorted will read no resistance as if you were checking both ends of one wire. Remember to disconnect the wires before checking.
Error #3 Grain T emperature Probe Open. This error is indicating the Grain T emperature Probe located in the drying chamber on a leleveleveling band is shorted.. The terminals for checking the Grain T emperature Probe are 22 and 23 and are labeled J7-14 and J7-18. The process for checking this error are the same as in error #1. Remember to disconnect the wires from these terminals before checking them.
Error #4 Grain T emperature Probe Short. This error is indicating that the Grain T emperature Probe is shorted. This is the same Probe as in error #3 and is checked like Error #2.
Error #5 Airflow Open. This error is indicating the airflow proving switch is in its open state and should be closed verifying there is no airflow so the fan heater will start. This must be checked with a Ohm meter and can be done directly on the airswitch terminals labeled N.O. And Common. This can also be checked on the terminal strip between terminals 12 and 14. They are labeled J7-09 and J7-10. The Airswitch can usually be adjusted and correct this error.
Error #6 Airflow Short. This error is indicating that the airswitch is stuck in both a normally open and normally closed state and needs to be adjusted, cleaned, or replaced.
Error #7 Illegal Flame Sense. This error is indicating that there was a flame sensed at a time it should not have. This is usually caused by a solenoid valve not closing properly . You can detect a solenoid not closing properly by watching the pressure gauge on the gas train. After the unit cycles off the pressure gauge will not drop immediately , it will gradually drop to zero or you can witch the flame and see if it is shutting off immedi­ately or gradually burning out.
Error #8 Flame Probe Short. When this Error is given it can be either the flame probe is touching a metal surface or The flame probe wire has shorted to ground somewhere. T o fix adjust the probe or replace the wire to the to of it.

W e use two (2) different types of sensors (NTC thermistor on the Series 2000, and an encapsulated sensor on the E.M.C.S ) in our dryers. The resistance of the sensors varies according to the outside temperature. For example, on the E.M.C.S. for every one (1) degree rise in temperature the resistance increases 4.8 ohms. However, on the Series 2000 dryer , the sensor reacts just the opposite, the resistance rises with colder temperatures. The charts displayed above will help when troubleshooting any sensor problems.

2. To F or ce a new time setting while the Dryer is runn ing Pus h the “Inc” (Up Arrow) and the “Dec” (Down Arrow) keys at the same time
3. To change the Second Fan Start delay hold down the “Program Dry/Cool Timers” and “Program Temperature” keys and turn on the power switch. Note this must be done on the Master Fan and cannot be done of the
Slave Fan or at the Remote Display.
4. Turning Dip Switch 3 ON disables the Air Flow monitoring function for testing. Remember to turn OFF before leaving the Dryer as loss of airflow will not shut down the dryer if the switch is left on.
5. You can select two modes for when the Drying Proces s stops.
A. Standard sett ing whic h will shut down if either Grain Temperature OR Dry Time is met. B. Optional setting in which both Grain Temperature AND Dry Time must be met.
To change this setting use the followin g steps.
1. While holding the Program Key in turn Power switch on. The Screen should read “0”
2. Release the Program button and press the “Inc” (Up Arrow ) key 3 time s. The screen should read “3”.
3. Press the Program Button until you see “NoL” (Sta ndard se tting) Press the “Inc” (Up Arrow) or “Dec” (Down Arrow) keys to change to “L”
on stand alone unit - 12 volt Ground for use with a tester.
NoL” - Will s to p drying when meeting either the Time OR Temperature Settings. “L” - Will stop drying only if both Time AND Temperat u r e S ett i n gs are met.
6. To Clear the NOVRAM Hold down the Program key (lower left key) and power the unit up. When the “0” comes up Enter a “7” with the Increment key (Up Arrow) and then push the Program Key again. When the “--- “ comes up you have 2 Seconds to depress the “Inc” (Up Arrow) and “Dec” (Down Arrow) keys at the same time. (Do not do this unless you are told to or are at a last resort to fix inconsistent behavior of the board)
7. When an Error shuts down the Dryer you can determine how long ag o the shutdown occurred by ushing the
“Dec” (Down Arrow) Key. It will read in hours with a maximum of 218 (9.1 days).
8. Drying Time has a minimum setting of 10 minutes no matter what time is set.

Error Messages
When the dryer shuts down the user can quickly determine what caused the shutdown by viewing the display on the dryer control panel. The Electronic Monitoring Control System displays the error message and sounds a warning signal to alert the user. The displayed error conditions and their electrical cause are as follows:
Burner 1 Loss Flame
The flame sensor in burner number one has failed to detect flame. Either the burner failed to light or the flame sensor needs to be adjusted. The flame sensor is the sensor attached to the burner, and has a single lead. If the burner is lighting but the unit is still shutting down due to loss of flame the flame sensor needs to be adjusted. The flame sensor can be adjusted by bending it so it is immersed in flame. If the burner is not lighting make sure that the dryer is getting fuel, all solenoids are opening, and the ignitor is sparking.
Burner 2 Loss Flame
and automatically resets itself when cool. The vapor­izer is adjusted by loosening the bolt and moving the vaporizer coil away from the flame.
Fan 2 V apor High Limit
The LP gas vapor temperature sensor located on the gas pipe train downstream from the vaporizer coil on fan and heater number two has opened indicat­ing that the vaporizer coil is running too hot and must be adjusted. This sensor is set at 200 degrees Fahrenheit and automatically resets itself when cool. The vapor­izer is adjusted by loosening the bolt and moving the vaporizer coil away from the flame.
Fan 1 Housing High Limit
The temperature high limit located on the housing on fan and heater number one opened, indicat­ing that the housing towards the bin has overheated. This high limit sensor is set at 200 degrees Fahrenheit and must be manually reset.

Fan 2 Housing High Limit
The temperature high limit located on the housing on fan and heater number two opened, indicat­ing that the housing towards the bin has overheated. This high limit sensor is set at 200 degrees Fahrenheit and must be manually reset.
Plenum High Limit
An over temperature condition has occurred inside the dryer plenum. The plenum high limit is set automatically on the Hi-lo thermostat when the cycle set-point is adjusted and resets automatically when cooled. The lo-fire gas pressure needs to be lowered, or the cycle setpoint on the Hi-lo thermostat needs to be increased if the error is displayed frequently .

Fan 1 Motor Overload
The thermal overload in the control box on fan number one has tripped, indicating an overcurrent condition. The overload must be reset manually .
Fan 2 Motor Overload
The thermal overload in the control box on fan number two has tripped, indicating an overcurrent condition. The overload must be reset manually .
Fan 1 Loss Of Airflow
The contacts on the airswitch, located in the bin sidewall and attached to fan and heater number one, have opened due to the fan not turning, or the airswitch may need to be adjusted.
Drying Chamber Overflow
Bin Grain High Limit Full
The grain level in the storage chamber has reached the storage chamber high level rotary switch located 3 feet below the fan and heater(s). Grain will have to be removed from the storage chamber before the unit can be restarted.
Bin High Limit Switch Bad
The storage chamber high level switch has failed. Both the normally open and the normally closed sides of the switch are in the same state.
Out Of Grain
The out of grain timer has ran for longer than it was set. Either you are out of grain or the fill system is filling to slow .
The grain level in the drying chamber has reached the drying chamber overflow rotary switch. Grain will have to be dumped from the drying chamber to the storage chamber before the unit can be restarted. This error indicates that either the drying chamber high level rotary switch is faulty or the time on the Load delay or Aux. 1 delay needs to be lowered.

This message is displayed when the start button is pushed and grain has fallen away from the wet supply rotary switch and there is still grain against the drying chamber low level rotary switch. If the enter button is pushed the dryer will restart, but the fill system(s) will not restart.
Cannot Start Dryer Wet Supply Empty
This message is displayed when the start button is pushed and grain has fallen away from the wet supply rotary switch and there is no grain against the drying chamber low level rotary switch. Grain will have to be put into the wet supply tank or the drying chamber to start the dryer.
Low Level Switch Exposed
This message is displayed when grain falls away from the drying chamber low level rotary switch after the Wet Bin Switch Delay has reached zero. If the error is being caused due to the settling of grain after the fans start the time on the Wet Bin Switch Delay can be lengthened.
The thermal overload in the fill system control box for fill system number one has tripped, indicating an overcurrent condition. The overload must be reset manually .
Fill 2 Motor Overload
The thermal overload in the fill system control box for fill system number two has tripped, indicating an overcurrent condition. The overload must be reset manually .

for use with a tester.
1. When ever you install a new display board. After you flash the software in and restart you may see an ERROR Message with some garbage characters or a negative number for temperature such as -2785 degrees. Do a Hard Boot by holding the Reset key and turn ing the power on to correct this stuck register value.
2.
Always do a Hard Boot after ins t alling a new Dis play board.
3.
If you have a blank or all black screen see the Contrast Adjustment in Tip #1
4. Also when flashing new software to the IO Board turn off the load auger breaker(s). Due to a design characteristic th e load auger(s) will run w h enever the IO b o ard is being f l as h ed.
5. If the Fan motors run, but the augers and aeration fan do not, make sure the 110 volt breaker on the IO oard is turned on.
6. The newest Display boa rds (5/1/ 02)ca n now be used on e it her a Topdry or Po rta ble Dr yer. In the past a
Dryer Display board had to have wires soldered in place for the Meter Roll Speed Pot and they can also be used on either a Top Dry or Portable Dryer. The past Top Dry Display board without these wires cou ld be used on a Top Dr y only. The newest boards now have a six pin connector that the Dryer Meter Roll Speed Pot is connected to.
7. If you get a plenum High Limit Error on startup w ith a new system or after installing new software on a
