Fan 2 Housing High Limit
The temperature high limit located on the
housing on fan and heater number two opened, indicat-
ing that the housing towards the bin has overheated.
This high limit sensor is set at 200 degrees Fahrenheit
and must be manually reset.
Fan 3 Housing High Limit
The temperature high limit located on the
housing on fan and heater number three opened,
indicating that the housing towards the bin has over-
heated. 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 3 Motor Overload
The thermal overload in the control box on fan
number three 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
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.
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 grain in the wet supply tank has fallen
below the wet supply rotary switch. If there is grain
against the drying chamber low level rotary switch the
dryer can be restarted by pressing the stop switch to
clear the error and then the start switch.
