RIPTION
The Eiki Slim Line series of portable halogen lamp projectors may be divided into thre
e
major model groups;
*
ESL, electronic touch button control slot load projectors utilizing a pre-programmed
ROM with addressable remote control functions.
*
SSL, conventional manual rotating function control with a .250 wa
tt low voltage haloge
n
lamp.
*
SSL-OL, a light weight version of the SSL without the transformer m
odule. This model
utilizes a 300 watt 120V halogen lamp. (Available
I
n
120V Main Power
UL &
CSA only
)
This manual will cover the mechanical functions of a
ll three groups together as they are very
similar. In the electrical section each model group wi
ll be treated separately

ELECTRICAL SYSTEMS
The Slim Line series projectors are available for voltage from 1 OOV, 11 OV, 120V
,
220V and 240V. 110/220V an
d l 20/240V dual voltage models are also available.
According to the electrical safety regulations of various countries, UL (USA), C
SA
(Canada), VOE (Germany),SEV (Switzerland), SAA (Australia), SEMKO (Sweden),
NEMKO (Norway), FEMKO (Finland), DEMKO (Denmark), specific models ar
e
manufactured to meet such regulations, including the option of 50/60Hz sound only.
50Hz soun
d & silent, 60Hz soun
d & silent operation.
Power Transformers vary according to the voltage range and also to the electrical
safety requirements of each country. The secondary windings of all transformer
s
provide 8V AC to the pilot lamp and exciter lamp circuits, 46V AC to th
e amplifier,
24V AC (high) and 22
V AC (low) to the halogen projection lamp
.
Motor ON/OFF
, Lamp ON/OFF and Rewinding ca
n be controlle
d by the functio
n
switch which consists of
a cam bracket an
d 4 micro switches. The function switc
h
cam also mutes the audio during rewind and the "STOP" or threadin
g position.
The projection lamp is a HALOGEN ELC type 24V 250W. Inside of the lamp hous
e
is a "high-low" switch to help extend the lamp life. In the "high" position averag
e
lamp li
fe is approximately 50 hours and a
t the "low" position about 150 hours
.
Not
e The HALOGEN LAMP EJ L type 24V 200W may also be used with some reduction i
n
light output
.
Models SSL-OL use the 300W 120V EWG or EYK lamp.
The motor is an induction type with capacitor. Motors are available for all the voltag
e
ranges. Transformers and motors are simple and easy-to-replace m
odules.
AC power cords, line terminals, and all other electrical parts are designed to mee
t
the safety requirements of the individual countries listed
.

EIKI SSL/ESL-series models are designed according to the sound playback capabilities an
d
front cover extension speakers.
Optical Playback only: Model SSL-OL, SSL-0
, -1, ESL-0, -1
Optical & Magnetic Playback: Model SSL-02, -2, ESL-
2
Model SSL-1, -2 and ESL-1, -2 are standard with two (16 ohm, 12.5cm) speakers built-in the
front cover, also with one (8 ohm, 10 x 15cm) speaker built-in the rear cover.
Model SSL-0 and SSL-02 are standard with one (8 ohm, 10 x 15cm) speaker only built-in th
e
rear cover
.
The standard amplifier modules for the SSL-0
, -1 a
nd ESL-0, -1 are optical sound reproduc
-
tion only.
Standard amplifier modules for the SSL-02, -2 and ESL-02, -2 are capable of both optical and
magnetic sound reproduction

PRECAUTIONS
1. El
Kl SSL/ESL-series projectors have been designed for the ultimate in simplicity, and ease
of service and repair. Each screw is very important, and when servicing or reassembling th
e
projector, screws should not be omitted or carelessly lost. All screw
s should be firml
y
tightened to assure reliable projector operation after disassembly
.
2. When lubricating the projector's plastic parts, silicone oil or grease should be used. Othe
r
types of lubricants may harm plastic parts.
3. El Kl projectors require a minimum of special tools. The most important is an ordinary ISO
Phillips screw driver set
.
4. To avoid damage to screw heads it is important to remember th
e adage "70% push, 30%
turn." It is also important to selec
t the right size screw driver blade. A rule of thumb is t
o
use the largest blade possible.
5. To avoid possible electrical shock, always disconnect the projector from the power sourc
e
when servicing
.

TOOLS AND TEST EQUIPMENT
A. Tools
:
When servicing El Kl SSL/ESL-series, ordinary ISO (Phillips type) screw drivers and single-
bladed screw driver
s should b
e enough
. (El Kl Screw Driver Kit, P/N 5615 ar
e available.
)
A Molex extractor tool is most useful when replacing the pins of nylon connectors t
o
transformer or motor
.
B. Special Tools:
El K
l
SSL/ESL-series have been designed so that no special tools should be required to
service the projector. However, several special tools are available to spee
d up adjustments
and maintain a closer consistency between the projectors

Test Equipment
:
A limited amount of test equipment is required for routine maintenanc
e and modula
r
replacement. However, when servicing the individual module
s such as the amplifier, th
e

TROUBLE SHOOTING HINT
S
A. There are four basic steps to trouble shooting this projector
:
a. Analyze the symptom
b. Localize the trouble to a functional system or modul
e
c. Repla
ce or repair that system or module
a. Isolate the trouble within the modul
e
b. Locate and repair the specific trouble
B. Checking Semiconductors With A VOM
:
a. Set the ohms scale to Rx 10
b. The forward resistance should be lo
w
c. The reverse resistance should be hig

(See NOTE after Sec. D)
Typical Amplifier Test Set-Up

C.
IC's are best checked by checking the signal input an
d output condition. This can b
e
done by inserting a low level audio tone into the MIC jack and the signal path from the
input of IC-1 and to the output of IC-2
.
D. Amplifier test cables can be easily made from locally available parts. A nine pin miniatur
e
tube socket and male plug can be wired as an extension power cable, allowing the ampli-
fier to be operated away from the projector. The solar cell and exciter la
mp connection
can also be extended if so desired. (Fig. #5)
Not
e Forward and reverse resistance LOW & HIGH is a suggested quick and easy check of
out of circuit components for shorted and open junction test. A VOM will not test the
quality of a semiconductor accurately
