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

BURNER 1, 2 OR 3 VAPOR

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.

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.

The contacts in the air switch have

opened due to insufficient airflow for the

burner to operate. The message will dis-

tinguish between burner 1 and 2.

in continuous flow operation.

The right circuit breaker on the input/

output board has tripped.

12 VOLT POWER

SUPPLY WARNING

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.

An over temperature condition has oc-

curred in the left side (left and right as

viewed from behind the dryer) grain col-

umn causing the control to shutdown the

dryer. This control is set at 210

°

F and

automatically resets itself when cool.

MOTOR OVERLOAD

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.

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.

FAN 1, 2 OR 3 HOUSING

HIGH TEMPERATURE

The temperature high limit located

on the fan/burner housing has
