Solenoid
Test
Run
this
test
to
evaluate
the
operation
of
the
solenoids.
Note:
You
can
also
manually
test
each
solenoid
by
pressing
on
the
actuator
button
on
the
side
of
each
solenoid.
WARNING:
Performing
these
diagnostic
procedures
will
expose
you
to
harmful
high
voltage.
Only
a
service
technician
trained
on
electromechanical
equipment
should
perform
the
diagnostic
tests
described
in
this
manual.
If
you
are
not
a
service
technician
who
has
been
trained
on
the
2500,
do
not
lift
the
main
plate
as
described
in
some
of
the
diagnostic
test
procedures.
From
the
Diagnostics
menu,
press
2.
The
2500
displays:
When
you
test
a
solenoid,
confirm
that
the
action
it
controls
is
taking
place.
If
it
is
not,
check
the
LED
mounted
directly
on
the
solenoid
to
see
if
it
is
illuminated.
Refer
to
Figures
5-15
and
5-16
for
the
location
of
the
solenoids.
An
illuminated
LED
on
the
solenoid
indicates
that
it
is
active.
Each
solenoid
is
turned
on
and
off
by
a
control
circuit
on
the
handler
controller
board.

Solenoids
on
the
Beam
(test
numbers
shown)
To
see
the
LEDs
on
this
board
(located
in
the
2500's
base),
loosen
the
two
corner
screws
that
hold
the
main
plate
in
position
on
the
base
and
raise
the
main
plate.
Figure
5-19
shows
the
location
of
the
board.
An
LED
on
that
board
illuminates
when
the
solenoid
control
circuitry
is
sending
a
signal
to
activate
the
solenoid.
If
the
LED
on
the
solenoid
is
not
on
during
the
test,
make
sure
that
the
logic
drive
circuit
associated
with
that
solenoid
is
operating
correctly.
Refer
to
the
table
below
to
determine
the
LED
associated
with
each
test.
If
the
LED
is
on
during
the
test,
you
can
be
fairly
certain
that
the
solenoid
driver
is
getting
the
proper
logic
signal.
Refer
to
the
table
below
to
select
and
enter
the
test
number
for
each
solenoid
you
wish
to
evaluate.
Press
ENTER.
Then
press
START
to

Motor
Test
The
solenoids
perform
the
following
operations
(confirm
that
LEDs
on
the
solenoids
turn
on
for
the
duration
of
each
test):
•
Blower
—
Turns
on
low
air
pressure
to
the
output
tracks.
There
is
no
air
on
the
input
track.
•
Cutoff
—
Turns
low
air
pressure
to
the
beam
on
and
off.
If
you
are
running
all
tests,
perform
the
cutoff
test
first
when
you
enter
the
diagnostic
tests.
At
the
start
of
the
diagnostic
tests,
the
beam
should
be
up.
Pressing
3
directs
air
to
the
beam,
allowing
it
to
rise.
Note:
After
you
run
this
test
you
must
press
RESET
to
exit
the
solenoid
tests
and
then
reselect
协
e
solenoid
tests.
If
you
do
not
press
RESET,
the
Beam
Up/Down
and
the
High
Pressure
tests
will
not
operate
correctly.
•
Beam
Up/Down
—
Directs
low
air
pressure
to
raise
the
beam.
Pressing
the
4
key
allows
the
beam
to
lower.
•
Blow
Off
—
Turns
on
low
air
pressure
to
the
chuck
tip
to
assist
in
releasing
a
device.
Feel
for
air
blowing
out
of
the
chuck
tip.
•
High
Pressure
—
Turns
on
high
pressure.
The
beam
will
lower
quicker
than
the
Beam
Up/Down
test,
which
uses
low
air
pressure.
•
Vacuum
—
Turns
on
the
vacuum
generator.
Place
your
finger
over
the
end
of
the
chuck
and
feel
the
vacuum.
•
Clamp
—
Activates
the
programming
module
holding
clamps.
They
should
both
advance
and
clamp
the
module.
To
exit
the
solenoid
