The
upper
loop
forming
system
is
improved
forming
and
keeping
a
larger
upper
loop.
The
lower
loop
forming
system
is
improved
forming
and
keeping
a
larger
lower
loop.
Sound
drum
system
like
“М”
series
is
used.
The
conventional
rubber
pinch
roller
has
been
deleted
and
the
buzz
roller
with
tension
spring
loaded
activates
also
as
the
pinch
roller
on
the
sound
head.
.
Wow
and
flutter
is
minimized.
The
adjustment
of
wow
and
flutter
is
easier
since
less
parts
are
used
in
the
film
path
near
the
sound
head.
.
The
rear
dampening
tension
roller
is
given
more
allowance
to
move
freely
to
absorb
the
jerky
take-up
and
minimize
wow
and
flutter.
.
The
flywheel
brake
is
added
to
stop
instantly
the
flywheel
and
the
sound
drum
rotation
at
"STOP"
position.
.
The
front
cover
is
fitted
firmly
on
the
projector
so
that
the
cover
would
not
come
off
too
easily
in
transit
or
when
the
cover
is
pushed
up.
.
The
lamp
house
door
has
more
ventilation
holes
on
its
top
to
cool
down
heated
parts
more
efficiently.

Amplifier
control
knobs
have
better
looking
and
are
easy

.
Control
knob
of
the
function
rotary
switch
is
mounted
more
firmly
avoiding
slippage
on
the

shaft.

321-1: PRINCIPLES OF OPERATIONS
1-1: MECHANICAL SYSTEM
Тһе EIKI SLOT-LOADING projector is
controlled by a single lock-out Rotary
Function Switch. When the rotary
function switch is positioned at;
“STOP”: Film path is fully open. Holding the
film by the finger tips, beginning at
entrance guide #1, pull the film along
the slot path as indicated by the orange
arrows. Attaching the film to the take-
up reel completes the film loading.
Turn Function Switch To;
Film path is now closed. Film perfo-
rations and No. 1, and 2 sprockets, cam
claw are engaged and the upper and
lower loops have been formed,
The PA (Public Address) system can be
used at this position.
"MIC":
"2;
“з”:
Motor runs advancing the film forward,
Projection lamp is on for forward pro-
jection.
“STOP”: Motor is off and the film stops.
Turn Function Switch counter-clock wise
to;
Rewinds the film through the film path.
Conventional rewinding from reel to reel
can also be done.

1-2: ELECTRICAL SYSTEMS
EIKI SL II-series projectors are available for volta-
gesranging from 100V, 110V, 120V, 220V and 240V.
110/220V and 120/240V dual voltage models are
also available. According to the electrical safety
regulations of various countries, UL (USA), CSA
(Canada), VDE (Germany), SEV (Switzerland),
SAA (Australia, SEMKO (Sweden), NEMKO
(Norway), FEMKO (Finland), DEMKO (Denmark),
specific models are manufactured to meet such
regulations, including the option of 50Hz, 60Hz,
50/60Hz operation.
Power Transformers vary according to the voltage
range and also to the electrical safety requirements
of each country. The secondary windings of all
transformers provide 8V AC to the pilot lamp and
exciter lamp circuits, 36V AC to the amplifier,
SL П Series
(1-3)
24V AC (high) and 22V AC (low) to the halogen
projection lamp.
Motor ON/OFF, Lamp ON/OFF and Rewinding
can be controlled by the function switch which
consists of a cam bracket and 4 micro switches.
The function switch cam also mutes the audio
during rewind апа the "STOP" or threading posi-
tion.
The projection lamp is a HALOGEN ELC type
24V 250W. Inside of the lamp house is a "'high-
low" switch to help extend the lamp life. In the
"high" position average lamp life is approximately
50 hours and at the "low" position about 150
hours.
NOTE: The HALOGEN LAMP EJL type 24V
200W may also be used with some re-
duction in light output.
The motor is an induction type with capacitor.
Motors are available for all the voltage ranges .
Transformers and motors are simple and easy-to-
replace modules. AC power cords, line terminals,
and all other electrical parts are designed to meet
the safety requirements of the individual countries
listed.
1-3: SOUND SYSTEM
EIKI
SLII-series
models
are
designated
according
to
the
sound
playback
capabilities
and
front
cover
extension speakers.
Optical Playback only: Model 51-0, SL-1
Optical & Magnetic Playback: Model SL-02, SL-2
(Note: EIKI SL П-ѕегіеѕ does not offer а magne-
tic recording model.)
Model SL-1, and SL-2 are standard with two
(4 ohm, 12.5cm) speakers built-in the front cover,
also with one (8 ohm, 12.5cm) speaker built-in the
rear cover.
Model 51-0 and 51-02 are standard with one (8
ohm, 12.5cm) speaker only built-in the rear cover.
The standard amplifier modules for the 51-0 and
SL-1 are optical sound reproduction only.
Standard amplifier modules for the SL-02 and SL-2
are capable of both optical and magnetic sound
reproduction.

321-2: SERVICE PROCEDURES
=
о
2-1: PRECAUTIONS
. EIKE SL II-series projectors have been designed
for the ultimate in simplicity, and ease of serv-
ice and repair. Each screw is very important, and
when servicing or reassembling the projector,
screws should not be omitted or carelessly lost.
All screws should be firmly tightened to assure
reliable projector operation after disassembly.
. When lubricating the projector's plastic parts
p Й
silicone oil or grease should be used. Other types
of lubricants may harm plastic parts.
. EIKI projectors require a minimum of special
tools. The most important is an ordinary ISO
Phillips screw driver set.
. To avoid damage to screw heads it is important
to remember the adage “70% push, 3096 turn."
It is also important to select the right size screw
driver blade. A rule of thumb is to use the largest
blade possible.
. To avoid possible electrical shock, always dis-
connect the projector from the power source
when servicing.
2-2: TOOLS AND TEST EQUIPMENT
Tools: When servicing EIKI 51 П-вепе5, ordi-
nary ISO (Phillips type) screw drivers
and single-bladed screw drivers should
be enough. (EIKI Screw Driver Kit, P/N
5615 are available.)
A Molex extractor tool is most useful
when replacing the pins of nylon con-
nectors to transformer or motor.
. Special Tools:
EIKI SLILseries have been designed so
that no special tools should be required
to service the projector. However, sever-
al special tools are available to speed
up adjustments and maintain a closer
consistency between the projectors.

TROUBLE
SHOOTING
HINTS
A.
There
are
four
basic
steps
to
trouble
shooting
this projector:
а, Analyze the symptom
b.
Localize
the
trouble
to
a
functional
system
or
module
c,
Replace
or
repair
that
system
or
module
a.
Isolate
the
trouble
within
the
module
b.
Locate
and
repair
the
specific
trouble
B.
Checking
Semiconductors
With
A
VOM:
a.
Set the
ohms
scale
to
R
x
10
b.
The
forward
resistance
should
be
low
c.
The
reverse
resistance
should
be
high

Fig. 25
.|C's
are
best
checked
by
checking
the
signal
input
and
output
condition,
This
can
be
done
by
inserting
a
low
level
audio
tone
into
the
MIC
iack
and
the
signal
path
from
the
input
of
IC-1a
through
IC-1b
and
to
ІС-2.
„Amplifier
test
cables
сап
be
easily
made
from
ocally
available
parts.
A
nine
pin
miniature
tube
socket
and
male
plug
can
be
wired
as
an
extension
power
cable,.allowing
the
amplifier
to
be
oper-
ated
away
from
the
projector.
The
solar
cell
and
exciter
lamp
connection
can
also
be
extended
if
so
desired.
(Fig.
=6)
Forward
and
reverse
resistance
LOW
&
HIGH
is
only
a
suggested
quick
and
easy
check
of
components
out
of
circuit.
This
test
is
only
for
shorted
and
open
junction
test,
А
VOM
will
not
test
the
quality
of
a
semiconductor
accurately.
A
skilled
tech-
nician
will
know
this
but
an
unskilled
technician
may
be
helped
by
making
the
VOM
check
and
repairing
the
amplifier
in
case
of
shorted
or
open
transistor.
