Selecting
a
Device
To
select
a
Task
from
the
list
presented
on
the
screen,
press
Tab
to
move
the
cursor
to
the
Task/Kit
list
box.
Use
the

highlight
a
specific
Task
name.
Press
to
start
that
Task.
If
the
Task
you
are
looking
for
is
not
displayed,
it
may
be
located
in
a
different
Task
database
file.
To
select
a
different
Task/Kit
database
file,
highlight
the
Task/Kit
Database
entry
line
and
press
F2.
Select
the
path
and
filename
of
the
Task/Kit
database
file
you

to
run
from
the
list
as
described
above.
A
list
of
processes
may
appear
depending
on
how
the
Task
was
written.
A
process
is
a
list
of
operations
that
will
be
performed
on
the
devices
in
the
Task.
If
a
list
of
processes
appears,
you
must
make
a
choice
similar
to
the
one
in
Figure
4-19.
Check
the
instructions
you
have
been
given
to
help
you
decide
which
process
to
select.
In
this
example,
the
only
difference
between
these
two
processes
is
that
one
does
not
call
for
labeling
the
device.
Select
the
desired
process
and
press
Other
prompts,
such
as
those
described
below,
may
appear
depending
on
the
types
of
devices
listed
in
the
Task.
Then
the
action
status
box
appears
showing
what
percentage
of
the
data
has
been
loaded.
A
Task-specific
device
list
may
appear
asking
you
to
select
from
several
device
IC
manufacturers.
Check
the
tubes
of
devices
you
will
be
running
and
select
the
appropriate
manufacturer
and
device
type
from
the
screen.
Use
the
and
keys
to
move
the
screen
cursor
between
devices.
Press
to
select
the
device
and

Preventive
Maintenance
This
chapter
describes
ProMaster
2500
theory
of
operation,
diagnostics,
and
preventive
maintenance
procedures.
Diagnostic
tests
are
described
for
the
motors,
solenoids,
optics,
switches,
and
programming
electronics.

information
in
this
chapter
is

WARNING:
Performing
some
of
the
diagnostic
procedures
in
this
chapter
will
expose
you
to
harmful
high
voltage.
To
avoid
electrical
shock
or
mechanical
injury,
only
a
service
technician
trained
on
electromechanical
equipment
should
perform
the
diagnostic
tests
that
require
lifting
the
main
plate
while
the
2500
is
on.

Operation
If
you
start
a
Task
with
an
incorrect
number
in
the
Parts
/tube
field,
press
STOP
and
then
LOWER
CASE
+
T.
Enter
the
correct
number.
Press
ENTER
and
then
START
to
continue
running
the
Task.
This
screen
also
indicates
where
TaskLink
expects
device
pin
1
to
be
located
when
the
device
is
in
the
input
track.
This
is
critical
for
correct
device
handling
and
insertion
in
the
programming
module
socket.
Make
certain
that
your
device
matches
this
positioning.
Refer
to
page
4-22
for
more
information
on
installing
devices
in
the
input
tube
holder.
The
system
automatically
downloads
the
data
file
defined
in
your
Task
or
prompts
you
to
insert
a
master
device.
If
the
Task
asks
you
to
load
RAM
data
from
a
master
device,
TaskLink
prompts
you
to
insert
the
master
device
to
be
loaded.
Place
the
device
in
the
input
track,
against
the
programming
station
stop
guide.
Be
careful
to
observe
the
correct
orientation
of
pin
1.
Close
the
hood.
The
2500
detects
the
device,
picks
it
up,
inserts
it
in
the
programming
module,
and
loads
the
device's
data
into
RAM.
After
the
load,
the
master
device
is
set
in
the
left
device
recess
near
the
labeler.
