Loss of Flame

The flame sensor failed to detect a burner flame, indicating that the burner has failed to light. There is a problem with the flame sensing circuitry or the dryer is not getting burner fuel. The burner switch light will be lit any time flame has been sensed by the burner controls.

Housing High Temperature

The temperature high-limit, located on the fan/heater housing has opened, indicating an over temperature condition has occurred toward the rear of the fan/heater housing in an oblong covered electrical box. This control is set at 200°F and MUST BE MANUALLY RESET.

Rear Discharge Warning

The lid on the grain discharge box has opened, indicating that grain is not being taken away fast enough at the discharge box.

Motor Overload

One of the thermal overloads on either the fan, load, unload or auxiliary motors has opened, indicating an over current condition. The overloads MUST BE MANUALLY RESET.

Grain High Temperature

An over temperature condition has occurred in one of the grain columns, causing the control to shut down the dryer. This control is set at 210°F and automatically resets itself when cool.

Out of Grain

The dryer has run low on grain, and the out of grain timer has timed out, shutting the dryer down. The unload auger will clean-out the dryer if in continuous flow operation.

Plenum High Temperature

An over temperature condition has occurred inside the dryer plenum. This control is a 300°F limit and automatically resets itself when cool. See Emergency Cooling Mode on Page 18.

No Airflow

The contacts in the air switch have opened due to insufficient airflow for the burner to operate. The contacts in the air switch have opened due to the fan not turning, or the air switch may need adjusting.

Air

The air switch contacts have closed prior to the fan starting, indicating a free wheeling blade or improper setting of the air switch.

Grain and Plenum High Temperature (Both at Same Time)

If both of these warnings appear on the screen at the same time, one of the two mechanical high-limits, located in each of the two grain columns, has been tripped due to heat exceeding their 200° setpoint or one or both have failed. They will automatically reset when the temperature returns below 200°.

NOTE: The emergency cooling feature will not function if either or both of these mechanical sensors are tripped.
