8. Safety Circuit Shutdown Messages
54 PNEG-1935 Vision Hybrid for Portable Dryers
020C - Burner #X Grain Overheat (Thermistor)
This error indicates that an over-temperature condition has occurred in one of the grain columns causing
the control to shutdown the dryer. This control is set at 210°F (99°C) and automatically resets itself when
cooled. This can be caused by a grain column plugged with trash or the meter rolls may be adjusted to run
too slowly. Feel the grain columns to determine which one may be causing the malfunction. If all the
columns are hot to the touch, check the meter roll settings. If all columns are not hot, examine the column
that feels the hottest. Make sure you can see the grain moving down the column screens.
020D - Plenum #X Temperature Sensor Shorted
This error indicates there is a shorted condition with one of the grain temperature sensors located inside
the left or right grain columns. This could be a shorted sensor or the sensor wires could be shorted.
020E - Plenum #X Temperature Sensor Open
This error indicates there is an open condition with the plenum temperature sensor located inside the
plenum chamber. This could be an open sensor or the sensor wires could have an open connection.
020F - Grain #X Temperature Sensor Shorted
This error indicates there is a shorted condition with one of the grain temperature sensors located inside
the left or right grain columns. This could be a shorted sensor or the sensor wires could be shorted.
0210 - Grain #X Temperature Sensor Open
This error indicates there is an open condition with the grain temperature sensor located inside the plenum
chamber. This could be an open sensor or the sensor wires could have an open connection.
0211 - Fan #X Contactor did not Close
The auxiliary contactor on the fan contactor did not close when the fans were supposed to be started.
Could possibly be a bad contactor or some wiring is loose.
0212 - Fan #X had Airflow Before Fan Power
The air switch contacts have closed prior to the fan starting, indicating a freewheeling blade or improper
setting of the air switch. The message will identify which fan caused the shutdown. This indicates that
12 VDC has been lost to terminal J4-04 on the fan/heater board.
0213 - Fan #X Network Connection Failed
This error is generated whenever the fan/heater board has lost its communications link with the
Input/Output board (upper control panel) and the master display board (lower control panel). Check the
Ethernet cable jacks to make sure they are plugged in tightly.
