ADJUSTMENTS
1.
Capstan
Alignment.
a) Check
horizontal
and
vertical
alignment
of
the
capstan
with
a
small
machinist's
square.
b)
If
the
shaft
is
not
in
perfect
alignment,
place
small
shims
under
the
motor
mounting
screws.
The
bottom
edge
of
the
capstan
must be
on
the
same
level
or
slightly
above
the
read
head
assembly.
This
ad
justment
should
be
checked
whenever
the
motor
assembly
is
removed
for
drive
belt
replacement.
2.
Pinch
Roller
Alignment.
a)
Visually
check
horizontal
alignment
of
the
pinch
roller.
b)
If
adjustment
is
necessary,
loosen
the
four
screws
on
the
pinch
r011er
spring.
(See
figure
6-3
in
the
Digitronics
manual.)
c) Check
the
vertical
alig
nm
ent
or
parallelism
between
the
pi
nch
roller
and
capstan
by
plac
ing a
feeler
gauge
between
the
rollers.
The
gap
spacing
sh
ould
be
equal
at
both
ends
or
tape
will
tend
to
skew.

until
solenoid
reactivates
and
give
an
additional
half

e)
If
the
force
is
less
than
2-1/2
pounds minimum, check gap
spacing
and
readjust
return
spring.
4.
Pinch
Roller-Capstan
Gap
Adjustment.
a)
Check
the
gap
spacing
between
the
pinch
roller
and
the
capstan.
The
gap
should
be
0.008
inch
with
the
pinch
roller
deactivated.
b)
If
adjustment
is
necessary,
loosen
the
two
allen
screws
that
hold
the
solenoid
assembly
to
the
front
panel.
c)
Adjust
for
an
0.008
inch
gap.
5. Brake Assembly Alignment.
a) Read a
tape
off-line,
stopping
tape
periodically.
The
feedhole
should
be
centered
over
the
photodiode
with
tape
stopped.
b) Reform
the
brake
spring
if
the
brake
armature
does
not
res
t
squarel
y
~
and
evenly
upon
the
poles
of
the
coil
assembly.
c)
If
the
tape
feedhole
is
stopping
slightly
past
the
photocell,
the
brake
spring
tension
should
be
increased.
6. Reader Checks.
a)
Depress
READ
indicator.
1)

1532 Punch
Motor
Delays
At
the
present
time
there
is
the
possibility
of
there
being
three
versions
of
the
punch motor
delay
circuitry
in
1532
I/O Consoles
in
the
field.
This
delay
is
to
provide time
for
the
punch motor
to
attain
full
speed
before
punching
data.
Adding
to
the
confusion
is
that
the
possibility
also
exists
that
there
are
two
versions
of
this
circuitry
shown
in
the
technical
manual. Depending
on
FCO
status
and
on
the
serial
number
of
the
1532,
neither
of
these
versions
may
reflect
the
actual
circuitry
in
the
1532.

PUNCH
CLEANING
PROCEDURE
This procedure
will
resolve
most
of
the
intermittant
bit
problems which
occur
during
punch
operation
without
extensive
disassembly
or
realignment.
Most problems
of
this
nature
stem from
dirt
buildup
in
the
Blocking Pawl
Assembly and
not
in
mechanical
alignment.
The
sluggish
movement
of
the
blocking
pawls cause
partially
punched
bits
at
the
beginning
and
extra
bits
at
the
end
of
a frame
or
block
of
"1's".
1.
Bit
partially
punched
(sluggish
block
movement
allows
partial
pawl
knee
break
to
occur
when
punching
first
"1",
therefore,
marking
but
not
cutting
through
the
tape).
2.
-
Extra
bit
after
punching a "1"
(sluggish
block
movement
doesn't
catch
pawl
in
time
to
cause
pawl knee
action,
therefore,
punching an
extra
bit).
A
high
degree
of
success
in
resolving
this
problem has been
attained
by
squirting
a
cleaning
solvent
into
the
blocking
pawls while
the
punch
is
operating
and punching
all
"1'
sn.
This
portion
does
not
require
paper
tape
in
the
punch and
the
whole mechanical
unit
can be
cleaned
in
this
manner. Take
care
not
to
get
caught
in
the
moving
parts
or
splash
solvent
on
the
relay
pullers.
Rinse
all
of
the
dirt,
old
grease,
and
oil
out
of
the
unit,
turn
off
'
the
punch, and
allow
at
least
30 minutes
for
the
felt
pads
in
the
unit
to
dry.
Oil
all
parts
of
the
unit
including
all
moving
joints,
blocking
pawls, and
felt
pads
with
a good grade
light
weight
oil.
Operate
the
unit
punching
all
"1'
s"
to
insure
thorough
oil
penetration.
~
CAUTION:
Be
sure
to
saturate
all
felt
pads
with
oil
as
failure
to
do
so
will
cause
the
punch~
wear
rapidly.
Run
a punch
test
to
insure
proper
operation
before
placing
the
unit
back
in
operation
and
be
prepared
to
realign
the
unit
if,
due
to
the
above men-
tioned
problems,
the
unit
had been
previously
misaligned
in
an
attempt
to
compensate.

TALOS
ASSEMBLY
BOARD
REPLACEMENT
If
the
capacitor-coil
assembly
board,
part
number 7051182-00,
is
replaced
on
the
teletypewriter
of
TALOS
1532's
below
sIN
165,
it
should
be
modified
to
the
same
shape
as
the
one
it
is
replacing.
The
board
(located
in
the
front
left
corner)
will
interfere
with
the
teletypewriter
door
latch
unless
it
is
modified
by
filing
off
the
corner
of
the
board.
The
board
has been
moved
to
a
new
position,
out
of
the
way
of
the
door
latch,
on
TALOS
1532's
sIN

Modification
For
Operation
In
Keyboard
Interrupt
Mode
1.
As
of
1973
SSN-688
and
DDG
NTDS
systems
and
others
for-
seen
may
desire
to
use
the
1532
I/O
Console
for
Tele-
typewriter
Keyboard
Interrupt
generation
in
the
mock-up
or
tactical
environment
or
both.
2.
To
place
the
1532
I/O
Console
constantly
in
keyboard
interrupt
mode
without
the
necessity
of
holding
keyboard
interrupt
indicator
switch
XDS22
constantly
depressed
it
is
suggested
that
pin
3
of
indicator
switch
XDS22
be
shorted
to
pin
5
to
effect
continuous
keyboard
interrupt
mode.
3.
This
continuity
may
be
selectively
switched
thru
the
usage
of
an
externally
attached
on-off
micro
switch
attached
to
the
1532
control
panel
front
and
wired
to
XDS22.
Alternately,
if
not
in
conflict
with
paper
tape
reading
requirements
on
site,
paper
tape
LEVEL SWITCH
52
may
be
wired
at
pin
10
and
1
or
2
or
3
as
desired
to
obtain
continuity
when
switch
is
in
positions
5
or
6-7
or
8
respectively.
4.
Any
such
modifications
to
the
1532
I/O
Console
are
unofficial
and
should
be
temporarily
plugged
only
as
necessary
on
site
and
removed
if
console
is
moved
to
any
new
usage.
