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.
Example: Burner #1 Plenum Overheat (Thermistor) on up to Burner #6 Plenum
Overheat (Thermistor) depending on the size of the dryer.
Thermistor bolt sensor is
located at the end of the conduit inside the plenum just inside the plenum door.
Plenum (#) Temperature Sensor Shorted
This occurs when the plenum temperature sensor leads have shorted together. The
sensor is located at the end of the conduit inside the plenum associated with the error.
The sensor is wired directly to the fan/heater interface, which one depends on the number
of plenums the dryer has. The error message will show in which plenum the short occurred.
Plenum Temp Sensor Ground - ( J3-02 )
Plenum Temp Sensor - ( J3-01 )
Plenum (#) Temperature Sensor Open
This occurs when the plenum temperature sensor or the wires to the sensor have opened.
The sensor is wired directly to the fan/heater interface, which one depends on the number
of plenums the dryer has. The error message will show in which plenum the open occurred.
Plenum Temp Sensor Ground - ( J3-02 )
Plenum Temp Sensor - ( J3-01 )
Burner (#) Grain Overheat
This occurs when the grain temperature in one of the grain columns has reached 210 F
degrees. The fixed temperature thermo disc has opened. This will automatically reset when
it cools down. You will have to check each grain column and make sure the grain is moving
down the column screen. The message will show on which fan/heater the error occurred.
Example: Burner #1 Grain Overheat on up to Burner #6 Grain Overheat depending
on the size of the dryer.
The grain overheat is wired directly to the fan/heater interface
board where the shutdown occurred. After the overheat closes again there should be a LED
on beside the Grain Hi Limit terminal J4-06. This is on the fan/heater interface board where
the row of LED’s are located. If you are using a voltmeter you should have 12 volts DC on the
following: (Remember when checking for 12 volts DC always put one probe of meter on the
DC negative.)
( J5-03 ) DC Negative
( J4-01 ) 12 Volt DC output LED should be on.
( J4-06 ) 12 Volt DC when closed (Grain Hi Limit) LED should be on.
Burner (#) Grain Overheat (Thermistor Sensor)
This occurs when the grain temperature in one of the grain columns 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 grain temperature falls below its set
hi-limit.
