DRYER CONTROL PANEL

SAFETY CIRCUIT SHUTDOWN MESSAGES

BURNER VAPOR HIGH

TEMPERATURE

The LP gas vapor temperature sen- sor located in the gas pipe train downstream from the vaporizer, has opened indicating that the vaporizor is running too hot and must be re- adjusted. This sensor is set at 200°F and automatically resets itself when cool.

BURNER WARNING FLAME

NOT DETECTED

The flame sensor has failed to de- tect a burner flame indicating that the burner has failed to light, there is a problem with the flame sensing cir- cuitry or the dryer is not getting burner fuel.

FAN HOUSING HIGH

TEMPERATURE

The temperature high limit located on the fan/burner housing has opened, indicating an over tempera- ture condition has occurred towards the rear of the fan/heater housing. This control is set at 200°F and must be manually reset.

GRAIN 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.

L1 VOLTAGE LOST

The left circuit breaker located on the input/output board of the Elec- tronic Monitoring Control System has tripped, or one of the hardware timers has shut down the dryer.

LOWER ADJUSTABLE

GRAIN HIGH

TEMPERATURE

An over temperature condition has occurred in the right side (left and right as viewed from behind the dryer) grain column causing the control to shut down the dryer. This control is set at 210°F and automati- cally resets itself when cool.

LOWER FIXED GRAIN HIGH TEMPERATURE

An over temperature condition has occurred in the left side (left and right as viewed from behind the dryer) grain column causing the control to shutdown the dryer. This control is set at 210°F and automati- cally resets itself when cool.

MOTOR OVERLOAD

One of the thermal overloads on either the fan, load, unload or aux- iliary motors has opened, indicat- ing an overcurrent condition. The overloads must be manually reset.

OUT OF GRAIN

WARNING/UNLOAD

CLEANOUT

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 au- tomatically resets itself when cool.

METERING ROLL DRIVE

SYSTEM FAILURE

The metering roll drive system has

failed to turn. A broken chain or

jammed metering roll is a possibility.

RIGHT METERING ROLL

FAILURE

The right (as viewed from behind the dryer) metering roll has stopped turn- ing, or the sensor has been damaged.

LEFT METERING ROLL

FAILURE

The left (as viewed from behind the dryer) metering roll has stopped turn- ing, or the sensor has been damaged.

12 VOLT POWER

SUPPLY WARNING

The right circuit breaker on the in- put/output board has tripped.

AUXILIARY SAFETY

SHUTDOWN

A shutdown has occurred due to an auxiliary installed safety feature.

BURNER SHUTDOWN

LOSS OF AIRFLOW

The contacts in the air switch have opened due to insufficient airflow for the burner to operate.

FAN FAILURE

NO AIRFLOW

The contacts in the air switch have opened due to the fan not turning, or the air switch may need adjustment.

FAN CANNOT START CHECK AIR SWITCH

The air switch contacts have closed prior to the fan starting, indicating a freewheeling blade or improper set- ting of the air switch.
