DRYER CONTROL PANEL
This is used to adjust the low speed
ofthe meteringroll whenthe2 speed
automatic moisture control feature
of the dryer is in use.
HIGH SPEED METERING
ROLL POTENTIOMETER
This is used to:
• Set the high speed of the meter-
ing roll when the two speed auto-
matic moisture control feature of
the dryer is utilized.
• Setthe speed of the meteringrolls
when the one speed automatic
moisture control feature of the
dryer is utilized.
• Set the speed of the metering rolls
during continuous flow operation
whenthemoisturecontrolisnotused.
• Settherateofgraindischargefrom
thedryer during theunloadcycle of
staged batch dryer operation.
DRYER POWER
START SWITCH
This switch starts and operates the
dryer based on switch settings. If
other switch settings are in the off
position, individual dryer compo-
nentscan beoperatedby turning the
drying mode switch to continuous
flow, pressing the dryer power start
button and then turning on the de-
sired dryer component.
LOW SPEED METERING
ROLL POTENTIOMETER
DRYER POWER
STOP SWITCH
Thisswitchstops all dryer functions.
If an automatic dryer shutdown oc-
curs, first determine and correct the
cause of the shutdown. Press the
dryer power stop button to reset the
dryer before restarting.
Note: If the load auxiliary motor
overload relay is being utilized in
the dryer control panel, this switch
will also control the operation of the
auxiliary equipment.
The unload switch turns the meter-
ing rolls and discharge auger on or
off, and selects the operation of the
metering rolls.
• Inthe2speed position if the mois-
ture 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
meteringroll potentiometer setting
depending on the control signal
UNLOAD SWITCH
The fan is turned on or off with this
switch. The on position operates
the fan continuously during staged
batch and continuous flow modes.
The auto position operates the fan
in staged batch during the dry and
cool cycle. The light comes on only
when air pressure is sensed.
FAN SWITCH
This switch is used to turn the
burner on or off. The auto posi-
tion operates the burner in staged
batch during the dry cycle. The on
position will operate the burner
only when the fan is running. The
burner light comes on only when
flame is detected.
HEATER SWITCH
from the moisture control thermo-
stat. The discharge auger will op-
erate continuously.
• Inthe 1speedposition, ifthe mois-
ture control switch is on, and the
drying mode switch is turned to
continuous flow, the metering roll
speed will operate at the high
speedmeteringrollpotentiometer
settingor turnoff dependingon the
control signal from the moisture
controlthermostat. The discharge
auger will operate whenever the
metering rolls are operating.
• Inboththe1speed or the 2 speed
position, if the moisture control
switch is off, and the drying mode
switch is turned to continuous
flow, the metering roll speed can
be manually controlled by adjust-
ing the high speed metering roll
potentiometer. Thedischargeau-
ger will operate continuously.
• Ifthedrying mode switch is turned
tostaged batch, the unload switch
should be set to the 1 speed posi-
tion.The dischargeaugerand me-
tering rolls will only operate dur-
ing the unload cycle of the staged
batch operation, and the speed of
the metering rolls is adjusted us-
ing the high speed metering roll
potentiometer.
Note: If the unload auxiliary motor
overloadrelay is being utilized in the
dryercontrolpanel, the same switch
will also control the operation of the
auxiliary equipment.
