1)
On
initial
start
‐
up
with
wet
grain,
it
is
advisable
to
let
the
dryer
run
at
operating
temperature
for
10
‐
20
minutes
before
starting
the
discharge
process.
2)
Move
Unload
Operation
switch
to
“ON”
position
(grain
unloading
light
will
come
on)
to
start
discharge
auger
system.
Note:
Metering
rolls
will
not
operate
unless
all
auger
systems
are
on.
3)
Move
Unload
Operation
switch
to
“METER”
position
and
with
the
Watlow
Moisture
Controller
in
MANUAL
(MAN)
mode,
adjust
the
percent
of
power
output
to
desired
discharge
rate
in
DC
volts.
(see
formula
&
charts
below
for
determining
initial
unloading
rate)
a.
Metering
Roll
Adjustment
The
dry
grain
discharge
rate
is
adjusted
by
changing
the
percent
of
power
output
coming
from
the
Watlow
Moisture
Control.
ARROW
DOWN
–
Will
increase
the
grain
discharge
rate
&
DC
volts
ARROW
UP
–
Will
decrease
the
grain
discharge
rate
&
DC
volts
NOTE:
The
Watlow
Moisture
Controller
operates
as
a
PID
tuner
in
cool
mode.
Because
of
this,
the
output
power
display
on
the
Watlow
Moisture
Controller
will
always
be
shown
with
a
minus
(
‐
)
sign
to
the
left.
This
is
an
absolute
value.

4)
Wait
at
least
one
(1)
hour
–
until
a
complete
cycle
of
grain
through
the
dryer
has
been
completed.
One
cycle
consists
from
the
time
the
grain
enters
the
top
of
the
dryer
to
the
time
it
is
discharge
from
the
metering
rolls,
and
the
dryer
has
stabilized.
Then
check
grain
moisture.
Note:
With
wetter
grain
it
may
be
necessary
to
wait
longer
to
check
samples.
5)
If
grain
is
too
wet,
decrease
Watlow
Moisture
Control
output
(decrease
DC
voltage)
and
repeat
step
4,
allowing
grain
to
stabilize.
6)
If
grain
is
too
dry,
increase
Watlow
Moisture
Control
output
(increase
DC
voltage)
and
repeat
step
4,
allowing
grain
to
stabilize.
7)
Repeat
the
steps
above
until
final
moisture
content
has
been
established
and
dryer
has
completely
stabilize
8)
With
the
moisture
now
stabilized
in
manual
mode,
note
the
voltage
present
on
the
DC
voltmeter.
9)
Switch
the
Watlow
Moisture
Controller
from
MANUAL
to
AUTOMATIC.
Press
the
Advance
Key
(GREEN)
once.
The

Use
the
UP/DOWN
arrow
key
to
change
it
to
AUTO.
Press
the
Infinity
Key
to
return
to
the
home
page.
10)
Adjust
slowly
so
that
the
drive
has
time
to
