The principal concern of the GSI Group, Inc. is your safety and the safety of others associated with grain drying equipment. This manual is written to help you recognize safe operating, troubleshooting procedures and some of the problems that maybe encountered by the operator or other personnel.
Wiring Reference Troubleshooting SPECIAL TOUCH SCREEN SETUP SCREENS Accessing various screens will enable you to make changes on how the dryer operates. Some of the features rarely need to be changed once the dryer has been setup. Most of the special screens are under the setup button on the main touch screen.
Wiring Reference Troubleshooting DRYER NETWORK LAYOUT The bootloader master node (Display I/O) connects to a CPU host (ICOP) via an RS232 serial connection to receive instructions and flash program data. The master node (Display I/O) then consumes these commands and data itself, or passes them on to the pertinent slave nodes.

Wiring Reference Troubleshooting DISPLAY INPUT OUTPUT BOARD ERRORS (BOARD LOCATED ON THE BACK OF THE LOWER DOOR) Viewing the Shutdown History The shutdown history can store over 256 shutdown warnings, if the dryer exceeds this amount, your oldest shutdown will be replaced with the current shutdown warning. You will be able to access the shutdown history by pressing the view button on the touch screen.
Wiring Reference Troubleshooting POSSIBLE MAIN INPUT OUTPUT BOARD ERRORS (BOARD LOCATED IN THE UPPER PANEL) The following is a list of possible errors that are generated with the input/output board. This board is located in the upper main panel. This board has a LED light beside each input and output on the board.
Wiring Reference Troubleshooting POSSIBLE MAIN INPUT OUTPUT BOARD ERRORS (BOARD LOCATED IN THE UPPER PANEL) Auxiliary Load Motor Overload This error indicates that the auxiliary load motor overload on the dryer has opened. Example: This might be a fill auger wired to the dryer. ( J2-10 ) DC Negative ( J1-01 ) 12 Volt DC output LED should be on.
Wiring Reference Troubleshooting POSSIBLE MAIN INPUT OUTPUT BOARD ERRORS (BOARD LOCATED IN THE UPPER PANEL) Out of Grain Timer Expired (continued) ( J2-10 ) DC Negative ( J1-01 ) 12 Volt DC output LED should be on. ( J1-06 ) 12 Volt DC when dryer is calling for grain (Grain Level Switch) LED should be on.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Fan (#) No Airflow The air pressure switch failed to close do to insufficient air pressure in the plenum. This is usually caused by a pressure switch out of adjustment, if the dryer is full of grain. The message will distinguish between which plenum caused the shutdown.
Wiring Reference Troubleshooting HOW TO ADJUST AIR SWITCH Air Switch locations. Upper Air Switch. Lower Air Switch. IMPORTANT: To adjust the air switch the grain columns need to be full of grain so that the plenum can build up air pressure and close the air switch. With the Load Auger, Fan, Heater, and Unload switches in the off posi- tion turn on the Control power then push the Dryer Power Start switch.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Fan (#) Motor Overload This indicates that one of the fan motor thermal overloads has opened. This overload is located in the fan/heater box associated with which fan motor overload has opened. The message will display in which fan the overload occurred.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Fan (#) Contactor Did Not Close This occurs when the fan contactor has failed to close on start up or opens after start up. We monitor an auxiliary set of contacts on the fan contactor as an extra safety. The Fan Aux.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Burner (#) Lost Flame Detection (continued) Example: Flame Loss #1 on up to Flame Loss #6 depending on the size of the dryer. CAUTION Make sure power is off while making the above adjustment !!!! Assuming you have established airflow.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Burner (#) Plenum Overheat (Thermistor Sensor) This occurs when the plenum temperature inside has reached a set overheat limit by the computer. You can activate the emergency cool mode by pressing the start switch. The fan and only the fan will run until the plenum temperature falls below its set hi-limit.
Wiring Reference Troubleshooting POSSIBLE FAN HEATER BOARD ERRORS (BOARD LOCATED IN THE FAN HEATER BOX) Burner (#) Grain Overheat (Thermistor Sensor)(continued) Example: Burner #1 Grain Overheat (Thermistor) on up to Burner #6 Grain Overheat (Thermistor) depending on the size of the dryer. The grain thermistor sensors are located in the conduit running inside the grain column.
Wiring Reference Troubleshooting PROCEDURE FOR LOCATING, TESTING & REPLACING A DEFECTIVE PLENUM TEMPERATURE SENSOR Symptoms of a bad sensor may include: Temperature readings that are not consistent with the ambient outside temperature or with a verified plenum temperature that has been taken with a thermometer. Erratic plenum display readings.
Wiring Reference Troubleshooting PROCEDURE FOR LOCATING, TESTING & REPLACING A DEFECTIVE GRAIN TEMPERATURE SENSOR Symptoms of a bad sensor may include: Temperature readings that are not consistent with the ambient outside temperature or with any known verified grain temperatures entering the dryer. Display readings of 255 degrees or -127 degrees.
Wiring Reference Troubleshooting PROCEDURE FOR LOCATING, TESTING & REPLACING A DEFECTIVE GRAIN TEMPERATURE SENSOR 10. Connect the red lead to either of the disconnected 26 ga. wires and make note of the reading. 11. Now move the red lead to the other disconnected 26 ga. wire and make note of this reading.
