DRYER CONTROL PANEL
SAFETY CIRCUIT SHUTDOWN MESSAGES
BURNER 1, 2 OR 3 VAPOR
HIGH TEMPERATURE
The LP gas vapor temperature sensor located in the gas pipe train downstream from the vaporizer, has opened indicat- ing that the vaporizor is running too hot and must be readjusted. This sensor is set at 200°F and automatically resets itself when cool. The message will dis- tinguish between burner 1 and 2.
BURNER 1, 2 OR 3 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. The message will dis- tinguish between burner 1 and 2.
FAN 1, 2 OR 3 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. The message will distinguish between fan 1 and 2.
BURNER 1, 2 OR 3 SHUT-
DOWN LOSS OF AIRFLOW
The contacts in the air switch have opened due to insufficient airflow for the burnertooperate. Themessagewilldis- tinguish between burner 1 and 2.
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.
LOWER ADJUSTABLE
GRAIN HIGH
TEMPERATURE
An over temperature condition has oc- curred in the right side (left and right as viewed from behind the dryer) grain col- umn causing the control to shut down the dryer. This control is adjustable from 80° to 220°F, and automatically resets itself when cool.
LOWER FIXED GRAIN HIGH TEMPERATURE
An over temperature condition has oc- curred in the left side (left and right as viewed from behind the dryer) grain col- umncausingthecontroltoshutdownthe dryer. This control is set at 210°F and automatically resets itself when cool.
MOTOR OVERLOAD
One of the thermal overloads on ei- ther the fan, load, unload or auxil- iary motors has opened, indicating an overcurrent condition. The over- loads 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 it is in continuous flow operation.
12 VOLT POWER
SUPPLY WARNING
The right circuit breaker on the input/ output board has tripped.
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.
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.
PLENUM 1, 2 OR 3 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. The message will distinguish be- tween plenum 1 and 2.
AUXILIARY SAFETY
SHUTDOWN
A shutdown has occurred due to an auxiliary installed safety feature.
FAN 1, 2 OR 3 FAILURE
NO AIRFLOW
Contacts in the air switch have opened duetothefannotturning,ortheairswitch mayneedadjustment.Themessagewill distinguish between fan 1 and 2.
FAN 1, 2 OR 3 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. The message will distinguish between fan 1 and 2.
