DRYER CONTROL PANEL
FAN SWITCH (7)
This is used to select the opera-
tion of the load auger. In both the
AUTO and MANUAL position the
load auger will operate if the dryer
is low on grain, and will automati-
cally shut off when the dryer is full.
In the AUTO position only, the
dryer will shut down after a prede-
termined period of time set on the
OUT OF GRAIN TIMER, or if grain
flow is interrupted to the dryer. The
switch will light whenever the load
auger is operating.
Note: When this switch is set
to AUTO or MANUAL it also con-
trols the operation of any auxiliary
load equipment being utilized,
such as an auxiliary auger or con-
veyor.
LOAD AUGER SWITCH (6)
This is used to select STAGED
BATCH or CONTINUOUS FLOW
drying. The switch will light only af-
ter the Electronic Monitoring Con-
trol System has been turned ON,
the safety circuit is okay and the
RESET button has been pressed.
DRYING MODE SWITCH (5)
HEATER SWITCH (8)
UNLOAD SWITCH (9)
The UNLOAD switch turns the me-
tering rolls and discharge auger
ON or OFF, and selects the opera-
tion of the metering rolls.
• In the 2 SPEED position if the
MOISTURE CONTROL switch is
ON, and the DRYING MODE
switch is turned to CONTINUOUS
FLOW, the METERING ROLL
SPEED will alternate between the
HIGH speed metering roll potenti-
ometer setting and the LOW
speed metering roll potentiometer
setting depending on the control
signal from the MOISTURE CON-
TROL THERMOSTAT. The dis-
charge auger will operate con-
tinuously.
• In the 1 SPEED position, if the
MOISTURE CONTROL switch is
ON, and the DRYING MODE
switch is turned to CONTINUOUS
FLOW, the METERING ROLL
SPEED will operate at the HIGH
speed metering roll potentiometer
setting or turn OFF depending on
the control signal from the MOIS-
TURE CONTROL THERMO-
STAT. The discharge auger will
operate whenever the metering
rolls are operating.
• In both the 1 SPEED or the 2
SPEED position, if the MOIS-
TURE CONTROL THERMOSTAT
is OFF, and the DRYING MODE
switch is turned to CONTINUOUS
FLOW, the METERING ROLL
SPEED can be manually con-
trolled by adjusting the HIGH
speed metering roll potentiometer.
The discharge auger will operate
continuously.
• If the DRYING MODE switch is
turned to STAGED BATCH, the
UNLOAD switch should be set to
the 1 SPEED position. The dis-
charge auger and metering rolls
will only operate during the unload
cycle of the staged batch opera-
tion, and the METERING ROLL
SPEED is adjusted using the
HIGH speed metering roll potenti-
ometer.
Note: When this switch is set to
AUTO or MANUAL it also controls
the operation of any auxiliary load
equipment being utilized, such as
an auxiliary auger or conveyor.
The fan is turned ON or OFF with
this switch. The ON position oper-
ates the fan continuously during
STAGED BATCH and CONTINU-
OUS FLOW modes. The AUTO po-
sition operates the fan in STAGED
BATCH during the dry and cool
cycle. The switch will light up when-
ever the airflow switch is sensing
airflow and the dryer is full of grain.
The power to the Electronic Moni-
toring Control System is turned
ON or OFF with this switch.
The dryer service light is turned
ON or OFF here. It also may be
set on AUTO, which turns the light
on while the dryer is running, and
off if a shutdown occurs.
This switch is used to turn the
burner ON or OFF. The AUTO po-
sition operates the burner in
STAGED BATCH during the dry
cycle. The ON position will operate
the burner only when the fan is run-
ning. The switch will light up when
the flame sensor detects the flame.
