If
the
device
programs
without
errors,
the
PE
goes
to
a
verify
cycle.
Most
semiconductor
manufacturers
specify
setting
the
device
Vcc
to
two
different
levels
during
the
device
verify
cycle,
one
above
and
the
other
below
the
nominal
operating
V^c-
All
fuses
in
the
device
are
verified
at
each
level.
This
tests
the
device
to
make
certain
that
the
correct
data
is
read
when
the
device's
Vcc
pin
is
set
slightly
below
and
above
the
nominal
Vcc
level.
The
PE
sets
the
device's
Vcc
Pin
to
the
specified
low
Vcc
level
and
verifies
all
the
fuses
in
the
device.
It
then
sets
Vcc
to
the
high
level
and
checks
all
fuses
a
second
time.
If
one
fuse
does
not
pass
this
test
when
Vcc
is
set
to
the
low
level,
TaskLink
displays
.
If
the
fuse
test
passes
with
Vcc
low
but
fails
to
verify
when
Vcc
is
set
to
its
high
level,
TaskLink
displays
.
When
the
device
passes
all
these
tests,
the
PE
sends
a
“pass”
message
to
TaskLink,
and
the
device
count
in
the
System
Log
is
advanced.
TaskLink
in
turn
sends
a
“pass”
category
signal
to
the
handler.
The
handler
uses
this
category
status
to
determine
whether
to
apply
a
label,
and
which
of
the
two
output
tubes
to
use.
Device
Moves
to
Labeler
If
the
device
programmed
correctly,
and
labeling
has
been
selected
in
the
task,
the
beam
moves
the
device
to
the
labeler.
If
the
device
failed
programming,
the
beam
places
the
device
in
the
failed
device
output
track.
Device
Is
Labeled
The
labeler
prints
a
label
and
the
labeler
motor
advances
it
between
the
platen
and
the
press
bearings,
into
position
to
be
applied
to
the
next
device.
The
beam
pulls
the
device
across
the
application
plate
and
press
bearings,
and
the
liner
wraps
around
the
platen
at
an
angle
that
allows
the
label
to
peel
off.
The
label
is
applied
to
the
device
as
the
beam
moves
the
device
forward
and
past
the
peeled
off
label.
The
label
drive
motor
and
the
ADC
optic
move
the
next
label
into
position
for
printing.
Device
Moves
into
Receiving
Tube
The
beam
moves
the
device
to
the
“passed”
output
track
and
releases
it.
The
default
designation
for
the
passed
output
track
is
output
track
1
(see
Figure
5-1).
The
device
release
optic
detects
the
device
in
the
track
and
the
output
orbital
motor
agitates
the
output
orbital
assembly,
helping
the
devices
slide
into
the
tube.
Devices
are
also
helped
into
the
tube
by
air
triggered
by
output
track
air
solenoid
3.
Output
tube
optics
(12
and
14
in
Figure
5-1)
detect
the
devices
as
they
enter
the
tube.
The
2500
counts
the
devices
as
they
pass
between
the
output
tube
optics.
When
the
device
count
reaches
the
number
set
in
the
Parts/Tube
parameter
in
the
task,
operation
stops
and
the
handler
displays
.
Operation
continues
when
a
microswitch
on
the
output
tube
clamp
toggles,
indicating
to
the
handler
that
the
full
tube
was
removed
and
an
empty
receiving
tube
has
been
inserted.
The
following
sections
describe
major
2500
subsystems
in
greater
detail.

Optics
Optics
detect
and
monitor
the
location
of
devices,
the
movement
and
position
of
the
beam,
labeler
movement,
orbital
motor
positions,
label
position
on
the
liner
(the
translucent

material),
and
position
of
the
ribbon
and
ribbon
pinch
roller
in
the
thermal
printer
(25
and
26
in
Figure
5-1).
The
optics
are
mounted
in
pairs
at
various
places
on
the
handler.
Each
pair
of
optics
is
made
up
of
an
infrared
light-emitting
device
(emitter)
in
line
with
a
light-sensitive
collector.
All
emitters
are
of
two
standard
types
and
can
be
exchanged
with
like
emitters
from
any
location
during
troubleshooting.
Emitters
are
identified
by
red-and-black
or
blue-and-black
wires
crimped
to
a
slide-on
connector.
Collectors
are
identified
by
blue-and-yellow
or
red-and-
yellow
wires.
Track
Optics
The
track
optics
monitor
the
presence
and
movement
of
devices
in
the
tracks.
Positioning
Optics
The
reference
position
optic
(17
in
Figure
5-1)
detects
when
the
beam
is
at
the
far
right
position
and
sets
the
encoder
to
“0,”
which
establishes
the
starting
position
of
the
beam.
Optics
3
and
4
detect
the
vertical
position
of
the
beam.
ADC
Label
Calibration
Optic
The
ADC
optic
on
the
dot
matrix
and
thermal
label
printers
senses
the
position
of
labels
on
the
liner
so
they
are
positioned
properly
for
the
print
head
and
applied
correctly
to
the
device.
This
optic
pair
detects
the
presence
of
a
label
by
using
the
liner
as
a
reference.
During
label
calibration,
light
from
the
emitter
passing
through
the
liner
is
sensed
by
the
optic
collector.
As
a
label
on
the
liner
travels
between
the
optic
pair,
the
decreased
light
level
is
detected.
When
the
amount
of
light
increases
again,
the
ADC
optic
interprets
that
change
as
the
end
of
the
label.
Label
Sensing
Optic
The
label-sensing
optic
on
the
dot
matrix
label
printer
monitors
the
label
liner
and
detects
when
the
2500
runs
out
of
labels.
Switches
A
mercury
switch
on
the
top
cover
senses
when
the
hood
is
open
and
causes
the
2500
to
display
a
warning
message.
The
2500
will
operate
with
the
hood
up
only
when
you
are
running
the
motor
diagnostic
tests.
A
mercury
switch
on
the
main
plate
senses
when
it
is
in
the
raised
position.
A
microswitch
on
the
input
tube
clamp
detects
the
presence
of
an
input
tube
(19
in
Figure
5-1),
and
each
of
the
output
tube
clamps
have
a
microswitch
that
detects
the
presence
of
an
output
tube
(20
and
21
in
Figure
5-1).
Switches
on
the
front
and
back
side
of
the
programming
module
engage
when
it
is
properly
installed.
If
the
switches
do
not
engage,
an
error
will
be
displayed.
Motors
Stepper
motors
are
used
on
the
2500
to
control
the
movement
and
labeling
of
devices.

The
beam
has
a
traverse
motor
(with
an
encoder)
that
moves
the
beam
along
the
lead
screw
in
its
horizontal
(left-to-right)
travel.
The
encoder
counts
the
number
of
steps
the
beam
travels
from
the
home
position
and
sends
that
information
to
the
main
board.
The
beam
assembly
also
has
a
beam
rotate
motor
that
controls
the
rotation
of
the
device
on
the
chuck.
The
2500
has
three
additional
stepper
motors.
The
label
drive
motor
(used
in
the
dot
matrix
printer
and
in
the
thermal
printer)
advances
labels
at
a
precise
rate
past
the
print
head
to
create
even
spacing
between
characters.
This
motor
also
advances
the
liner
so
the
label
contacts
the
device
according
to
the
position
defined
by
the
label
placement
value
specified
in
the
Task.
The
input
orbital
motor
rotates,
causing
the
input
orbital
assembly
to
shake.
This
shaking
helps
the
devices
slide
from
the
input
tube
to
the
input
track.
The
output
orbital
motor
performs
a
similar
function
when
devices
are
sliding
from
the
output
track
to
the
output
tubes.
Solenoids
The
handler
uses
air
solenoids
that
are
activated
by
signals
from
MOSFET
circuitry
on
the
controller
board.
When
the
correct
logic
drive
signal
for
a
specific
solenoid
is
active,
an
LED
associated
with
that
circuit
is
lit.
Beam
and
Chucks
The
microprocessor-controlled
beam,
using
a
pick-and-place
head
and
an
interchangeable
vacuum
chuck,
picks
up
and
places
devices
at
the
programming
or
labeling
station
and
releases
devices
into
the
output
track.
The
beam
traverse
stepper
motor
drives
the
beam
on
the
horizontal
(left-
to-right)
axis
along
the
lead
screw.
You
must
keep
this
lead
screw
clean
and
lightly
lubricated
to
ensure
correct
beam
operation.
If
you
do
not
keep
the
lead
screw
clean,
the
beam
may
eventually
develop
alignment
problems
and
fail
to
locate
the
center
of
a
device.
Beam
stalling
is
a
term
used
to
describe
the
failure
of
the
beam
to
travel
freely
on
the
lead
screw,
resulting
in
lost
steps
and
the
inability
to
travel
the
full
distance
of
the
lead
screw.
The
chance
of
this
occurring
is
very
low,
because
the
beam
traverse
motor
has
an
encoder
that
keeps
track
of
the
beam's
movement.
A
device
rotate
motor,
which
is
mounted
on
the
beam
assembly,
is
connected
to
the
beam
head
by
a
timing
belt.
The
device
rotate
motor
controls
the
rotation
of
devices
on
the
chuck
so
that
the
device
orientation
can
be
adjusted
for
programming
or
labeling.
