DRYER CONTROL PANEL
CONTROL POWER
SWITCH
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.
OUTSIDE LIGHT
This is used to select staged batch
or continuous flow drying. The
switch will light only after the Elec-
tronic Monitoring Control System
has been turned on, the safety cir-
cuit is okay and the reset button
on the control panel has been
pressed.
DRYING MODE SWITCH
LOAD AUGER SWITCH
FAN SWITCHES
Each fan is turned on or off with
this switch. The on position oper-
ates 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 switch will
light up whenever the airflow
switch is sensing airflow and the
dryer is full of grain.
HEATER SWITCHES
Each burner is turned on or off with
this switch. The auto position op-
erates the burner in staged batch
during the dry cycle. The on posi-
tion will operate the burner only
when the fan is running. The
switch will light up only when the
flame sensor detects the flame.
UNLOAD SWITCH
The unload switch turns the meter-
ing rolls and discharge auger on or
off, and selects the operation of the
metering rolls.
• In the 2 speed position if the moisture
control switch is on, and the drying
mode switch is turned to cont. flow,
the metering roll speed will alternate
between the high speed metering roll
potentiometer setting and the low
speed metering roll potentiometer set-
ting depending on the control signal
from the moisture control thermo-
stat. The discharge auger will oper-
ate continuously.
• In the 1 speed position, if the mois-
ture control switch is on, and the dry
ing mode switch is turned to cont.
flow, the metering roll speed will op-
erate at the high speed metering roll
potentiometer setting or turn off de-
pending on the control signal from
the moisture control thermostat. The
discharge auger will operate when
ever the metering rolls are operating.
• In both the 1 speed or the 2 speed
position, if the moisture control
switch is off, and the drying mode
switch is turned to cont. flow, the
metering roll speed can be manu-
ally controlled by adjusting the
high speed metering roll potenti-
ometer. 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 posi-
tion. The discharge auger and
metering rolls will only operate
during the unload cycle of the
staged batch operation, and the
speed of the metering rolls is ad-
justed using the high speed me-
tering roll potentiometer.
(Note: If the unload auxiliary
motor overload relay is being uti-
lized in the dryer control panel, this
switch will also control the opera-
tion of the auxiliary equipment.)
This is used to adjust the low speed
of the metering roll when the 2 speed
automatic moisture control feature
of the dryer is in use.
This is used to select the opera-
tion of the fill auger. In both the
auto and manual position the load
auger will operate if the dryer is low
on grain and will automatically shut
off when the dryer is full. In the auto
position only, the dryer will shut
down after a preset period of time
set on the out of grain timer, or if
grain flow is interrupted to the
dryer. The switch will light when-
ever the load auger is operating.
(Note: If the load auxiliary mo-
tor overload relay is being utilized
in the dryer control panel, this
switch will also control the opera-
tion of the auxiliary equipment).
