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

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

.

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

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)

out of circuit components for shorted and open junction test. A VOM will not test the
quality of a semiconductor accurately

(6) Change to the side that has the larger "V" notch and the claw should move freely

.

e. When using another type of claw protrusion gauge of similar specifications as

(322-4-1-A), disregard Item (d) and follow the instructions associated with that gauge.

2. Claw Position And Framing Adjustments:
a. If the claw does not enter the center of the

film perforations, or if the framing adjust-

ment is insu

fficient, the claw position should be adjusted. This adjustment can be eithe

r

horizontal or vertical. To adjust, slightly loosen the two screw

s

(

C) of the fulcrum assy.

shown in Fig. #17.

(1) Framing Adjustment: This is best accomplished with the projector running, showin

g

a shop test film. With the framing contro

l lever in the up position, the fra

me bar o

f

me bar shoul

d

appear as in Fig. #20.

Fig. #19

tion of the fulcrum assy.

by slightly loosening screws (

C) (Fig.#l 7)The fulcrum assy.

requires only a very small movement to effect the framing position

.

Note : If framing range as indicated cannot be reached, check for a worn ca

m

follower (or cam glidin

g pin. 312-11641) (Fig. #17

)

(3) Checking Position For Correct Alignment With The Sprocket Holes: To view the

claws position in the sprocket holes, thread a strip of good

film. Remove the film

shoe and bracket assy. With a standard 50mm (2") lens installed, look through th

e

lens. Focus a

E. REPLACING THE CLA

W

When replacing a worn or defectiv

e claw, it is important to mountthe claw correctly before

securing the mounting screws. Incorrect claw mounting may result in excessive film gate noise

or unsteady picture

.

International Dimension o

f the 16mm Film

Fig

.

#

23

- 31

-

1. Correct Claw Pitc

h

a. The international dimensions of the 16mm film are shown in Fig. #23. Claw pitch is set

at 7.64 - 7.67mm. A pitch less than 7.64mm will cause the claw to engage the film
between perforations possibly causing film damage or unsteady pictures.

b. A pitch more than 7.67mm will caus

e excessive gate noise. Typical film perforation

should have a pitch of 7.605 - 7.635mm, but older films may have a smaller pitch du

e

to shrinkage

.

c. The cla

w a

s shown in Fig. #24 has a 5° angle at the top tooth, and should the claw pitc

h

become larger than the pitch of the perforations, this would help prevent a

ny fil

m

damage.

Fig. #

24

2. Adjusting of The Claw Pitc

h

a. Moving the fulcrum control assy.: Fig. #25 shows the correct position between the cam

and the cam follower (cam gliding pin, 312-11641 ). The contact point of the cam
follower with the cam will change the pitch

. Moving the fulcrum control assy. to the lef

t

decreases the pitch and moving it to the right increases the pitch.

b. The fulcrum control assy. should only be moved slightly. Too much adjustment wil

l

cause the claw to hit the sides of the film perforations causing film jitter

.

c. Correct claw angle is shown in Fig. #26-A. Under some circumstances a bent claw lever

as shown in Fig. #26-B and -C may have t

o be corrected by straightening out the claw

.

-

32

-

3. Claw Lever Tension
(See Fig. #25

)
The claw lever tension force should be from 1.2 to 1.25kg when the spring is stretched to
the maximum travel of the claw lever arm. If the tension is too weak, the cam followe

r

may float off the cam surface causing excessive gate noise and an unsteady picture. On th

e

other hand, if the spring is too stro

ng the cam follower may wear out prematurel

y or cause

a slight hesitation to the claw lever when the projector is initially started. T

o obtain the

correct tension it may be necessary to replace the spring. A slight adjustment can be mad

e

by stretching the spring if necessary.

F. CHANGING SHUTTER BLADE

S

Fig. #27

Two, three a

nd five bladed shutters ca

n be mounted on the shutter hub. The mounting hole

s

used to secure the blades to the hub allow a small adjustment for shutter blade timings

.

Incorrect shutter timing results in what is commonly called "travel ghost". Th

e adjustment i

s

accomplished using the SMPTE test film and adjusting the blade position

for minimum upper

or lower image movement a

s shown in Fig. #27. Since the adjusting screws are only a

ccessible

with the cam tank removed, this becomes a trial and error adjustmen

t. However, the skilled

technicians can accomplish this in one or two adjustments

.
When mounting a 2 blade shutter to the center hub, the recessed circle of the blades must be
toward the side where the 3 mounting screws are located.
The relationship o

f the shutter blade to the indexing semicircle on the hub must be a

s

illustrated in Fig. #28. 3 blade shutters will always index correctly.

G. STILL PICTURE CLUTCH MECHANISM

1. Description

:

The still picture control "RUN-STILL" (32) i

s spring loaded and snaps into position whe

n

operated

.

When placed in the still mode the wire cable tension is released, dropping the (54) hea

t

filter in front o

f the projection lamp.

A

t the same time the "RUN-STILL" lever moves the shutter (39) and clutch hub assembly
away from the shutter pulley (42), disengaging the shutter blade and cam shaft.
The shutter pulley (42) is now free to rotate on the cam shaft withou

t turning the camtan

mechanism

2. Adjustment:
(a) In the run position the spacing between the clutch lever and the inside flange of th

e

shutter hub shoul

d be approximately 0.2mm (see "Fig. #32). Adjust the set screw

(322-11331

)

Fig. #32

for correct spacing and secure the jam nuts. The above adjustment is critical for proper
clutch action. If the space is too large, th

e clutch will not release in still and if th

e

space i

s smaller, the clutch will slip in run

.

(b) The correct position of the heat filter is determined by the cable tension.

In the run position the cable is tight

, holding the heat

filter above th

e aperture open

-

ing. Adjust the white duracon wire guide position to insure that the heat filter is

clear of the optical path (see Fig

. # 33)

- 36

-

The angle of th

e wire guide should also be adjusted so as to provide a straight pull to

the heat filter lever

.

Fig. #33

The heat filter lever i

s spring loaded and in the sti

ll position the cable should provide

sufficient slack to allow the heat

filter to drop in front of the lamp.

(c) The above adjustments should b

e checked whenever a cam ta

nk module has bee

n

removed an

d re-installed

Audio Amplifier Circuit

The input from the solar cell or magnetic head is accomplished through the 5 pin connecto

r

and switched to their appropriate impedance loading circuit. Models with optical soun

d

capab

ilities only hav

e amplifiers without the opt/mag switch. The input signa

l is route

d

through the MIC jack and coupled to IC-1 (AN-370) via capacitor C-3 and resisto

r R-6

.

R-8, 9 and 10 C

-8 and 9 form the opt/mag input equalization network, with fee

d back from
the tone controls V R-1 and V R-2.
Tone control equalization is accomplished by R-13, 14 and 15 and capacitors C-13, 14, 16
and 1 7

.

From the tone controls the signal is coupled to the pin 2 of IC-2 (AN-370) via C-18 and R-15,

and IC-2

.

The output of IC-2, pin

-6 is coupled through C-23 and R-20 to VR-3 (volume control}. Th

e

wiper of VR-3 is coupled through C-25 to the base of TR-1 amplified and coupled to the base

of TR-2, from TR-2 the signa

l is phase split to intermediate drivers TR-3 and TR-4 respec-

tively. The final complimentary drivers TR-5 and TR-6's emitter are coupled to R-36 an

d

R-37 through C-33. The final driver to the speaker jack is from the negative side of C-33 an

d
ground. Note that the output to the rear cover speaker jack is switched through the external
speaker jack.
600 ohm un-balanced aux line output is available through the external speaker jack provide

Adjustmen

t

a. Tension of the Side Pressure Sprin

g

The proper tension is about 60 - 75g. Excessive tension will cause earlier film wear

,

while insu

fficient tension causes an unsteady picture. The adjustment of tension can b

e

made by bending or straightening the spring. A weak or incorrectly formed sprin

g

shoul

d be replaced.

b. Outer Guide Rail Positio

n

When the film is loaded, the center o

f the

film should align with the center of the

aperture. To accomplish this, adjust the position of the outer rail.

B. Film Shoe And Bracket Assembly

1. Description

2. Removable Film Sho

e and Bracket Assembl

y

The spring loaded film shoe (1) is mounted to a bracket (3) and is easily removable as an

assembly for cleaning and servicing the film gate

.

The film shoe and bracket assembly is then seated in the reception bracket (9). The recep-

tion bracket is linked to the loading mechanism which opens and closes the film gate as the

function switch is activated.

-

47

-

3. Adjustmen

t

a. Uneven Focus

Uneven focus occurs whenever the image o

f the film is not flat and perpendicular to the

optical path of the lens. Since the lens holder assembly is mounted directl

y on the

projectors casting, any adjustment would have to be as a result of improper mountin

g o

f

the Lens Holder

.

To compensate for sma

ll tolerance differences in the projectors main casting, the lens
holder bracket is fitted with 2 small set screws. When removing or replacing the lens
holder assembly, careful I adjustment of the set screws for even side to side focus i

s

required

.
When performing this procedure, projector must be absolutely perpendicular to the
viewing screen and the lens focused for a sharp center image

.

It is a good idea to use a test film with a continuous pattern since many production

films purposesly use out of focus images to achieve special effects.

Loosen the small phillip

s screws and adjust the set screws t

o obtain an even focu

s

condition then secure the small phillip screws.

Fig. #47

b. Film Shoe Pressur

e

The pressure of the film sho

e against the film is maintained

by two small tension springs

between the shoe and the mountin

g bracke

t. Excessive tension will cause unn

ecessar

y
film wear, and insufficient tension can cause an unsteady picture, excessive film gate
noise and uneven or erratic focus. To tes

t the film shoe pressure, insert a stri

p o

f film in
the gate, close the gate. Attach a gram scale to the end of the film at the top. A gentle
but stea

dy pull should produc

e about 90 to 110 grams of pull, indicating the correct

film shoe pressure. To adjus

t this pressure, stretch, shorten or replace the shoe springs.

c. Film Shoe Positio

n

With the gate closed, the film shoe should line up along the edge of the outer guide rai

l

and seat evenly against the aperture plate. To adjust the position of the film shoe, clos

e

the film gate by setting the

function control to the "MIC" position. Loosen the two
screws (6) and align the film shoe with the outer guide rail, making sure that the shoe is
flat agains

t the aperture plate and secure the screws (6).

TAKE-UP ARM

A. Description

The drive to the take-up arm is obtained through the take-up clutch mechanism (items 22-32)

during normal forwar

d projection. Durin

g rewind the motor is reversed, disengaging th

e

clutch cam (31) removing all drive to the take-up arm. In forward the drive is transmitted vi

a

the drive pulley (5) to th

e arm belt and the take-up spindle (6). Th

e amount of take-up
torque is controlled by the friction of the belt against the pulley (5) and spindle pulley (6).
The amount of friction is adjuste

d by a combination of the tension sprin

g (

11)

and th

e

weight of the take-up reel

.

- 49

-

B. Adjustments

1. Take-Up Torqu

e

The take-up arm belt must be kept clean with the blue side of the belt positioned towards

the pulleys. Avoid any oily substances on the belt. Clean the belt with lsoprophyl Alcoho

l.

The take-up tension is adjusted by increasing or decreasing the belt tension with the

adjustment screw (13). This tension should have a range from approximately 90 grams t

o

150 grams, depending on the reel size. Torque in excess of 150 grams should not b

e
permitted on small film reels. Under normal operation where small to medium size reels are
used, the tension screw should be adjusted to where it barely makes contact with the

tension spring (1 mm to 3mm). Clockwise adjustment increases the take-up torque. Counte

r

clockwise adjustment decreases the take-up to

rque.

2. Take-Up Clutch Mechanis

m

The take-up clutch mechanism requires no lubrication. The clutch cam, clutch cover and
drive gear should be kept clean and free from dir

t. A sma

e

drive pulley shaft is su

fficien

During forward the supply arm only serves as a drag to provide

a small amount of bac

LOWER LOO

P SETTER SYSTE

M

A. Description

The lower loop setter mechanism is an integral part o

f the loading mechanism which i

s

controlle

d by the function switch. At the "STOP" position the loop setter gear (9) is raised

up away from the main drive belt. The loop setter arm (1) and the lower loop setter roller (2

)

is locked in the dow

n position,

functioning as the lower loop former while loading the film.
Rotating the function switch to the "MIC" position, the stop plate (14) is pushed to the left
by the protruding tab of the main interlockin

g bracket until the loop setter interlocking ar

m

(5) is released away from the sto

p plate (14). While the protruding tab on the interlockin

g

bracket is pushing the stop plate, the film is seated in the #1 sprocket sho

e and the fil

m

gate is completely closed. The loop setter roller is then raise

d up away from the film an

d

the loop setter gear is lowered into position near the main drive belt. In this position the loo

p

setter is ready to b

e activated by any small amount of film pressur

e against the loop sette

r

roller. When the loop setter roller is activated, the loop setter gear engages with the main

drive belt, causing the eccentric gear to cycle the loop setter mechanism, pulling down the
film from the gate, thus forming a new loop. In "Rewind" and "Stop" the lower loop sette

r

roller is locked in position to guide and dampen the tension of the film during high speed

rewind.

-

52

-

B. Adjustments

1. Position of the Lower Loop Setter Roller

:

With the function switch in the "Stop" position, the loop setter roller must lock into
the position as in Fig.# 55

.

Fig. #55

To check for the correc

t

positro

n

of the loop setter roller

, set the function switch at

"STOP". The distance between the outer edge of the roller and the main frame casting
should measure 5.5mm. In this position, the film should clear the aperture plate, the film
shoe, and sound drum when rewinding. To adjust the rolle

r position, set the function

switch to "STOP". Loosen the set screw on the loop setter interlocking arm, position th

e

loop setter rolle

r 5.5mm up from the main frame casting as Fig. #55. Then tighten the se

t

screw. To obtain the correct position of the loop setter roller tool No

. 185-01111 (Fig.

# 56) may be used

.

(

1) Se

t the

function switch at "STOP"

.

(2) Apply the tool No. 185-01111 as Fig. #57. Push the roller against the tool

.
(3) Loosen the interlocking arm set screw.
(4) Adjust the position of the interlocking arm and secure the set screw

.

- 53

-

2. Interlocking Arm and Stop Plate Clearance:
The correct clearance with th~ function switch in the "MIC" position is shown in Fig. #5

8

When the loop setter gear cycles, the ti

p of the interlocking arm should clear the end of the

sto

p plate. Where it contacts the stop plate, the clearance is adjusted by slightly reforming

the tab o

ri the main interlockin

g bracket. (Fig. #58

)

CAUTION

Avoid over-bending. Too much of a bend will cause the interlocking arm to release too
early, forming too small a lower loop

.

3. Loop Setter Gear And Main Drive Belt Clearance

:

The correct clearance is indicated in Fig. # 58

.

Insufficient clearance will cause the loop setter roller to be to

o

sensiuv

e

or cause it t

o

cycle continuously. Too much clearance will cause poor sensitivity and the loop sette

r

will not reset the loop unless the

film is severely damaged. To adjust, simply reform the

belt support plate and tighten the mounting screw.

Fig. #58

-

54

-

4. Loop Setter Tension Springs

Fig. #59

Correct adjustment of the loop setter tension springs is essential to the proper operation o

f
the automatic loop setter.
a. The loop setter gear sprin

g 320-18061 (7) acts as a dampener to the rotation of th

e

loop setter gear.

Too strong a spring tension will cause a sluggish action of the loop setter while to

o

weak a spring will cause the frequent and errati

c action of the loop setter

.

The spring ca

n be adjusted by simply stretching or compressing it to obtain a smooth

but dampened rotation of the loop setter gear

.

b. The arm spring 322-18111 (11) adjusts the tension of the loop sette

r arm and roller.

Too tight a spring will cause the loop setter to be ineffective where too loose a spring

will cause erratic rotations o

f the loop setter gear.

To adjus

t the loop setter's tension, change the position of the spring arm (12) until

the loop setter function operates smoothly.

5. Loop Setter Timin

g

To check the loop setter timing, load the projector with film, advance the function control

to position (j) and operate the projector. While observing the loop setter, insert a finger in
the upper loop causing the lower loop to loose one frame. With onl

y one frame lost, the

loop setter will not activate. Loose one more frame. At this time the loop setter should be

activated by t

oo small a lower loop, causing it to reset the lower.Ioop once only. If it

requires holding the upper loop for more than two frames to activate the lower loop, th

e

low

er loop is too large. If the lower loop is always in contract with the loop setter roller

,
the lower loop is too small.
The correct lower loop should not come in contact with the loop setter roller, but at
the sa

me time the loop setter should easily activate when two frames of defective sprocke

t

holes pass through the film gate

.

a. To increase the size of the lower loop, loosen the #2 sprocket cover screw and rotat

e

the sprocke

t teeth plate in the clockwise direction until the correct size lower

loop is obtained. (Fig. #60

)

2. Upper Loop Forming Roller And Film Guard
a. Function: The position of the upper loop forming guide roller is determined by th

e

position of the function switch

;

Position A: The

function switch is at "STOP" position for the film loading, or at

(Fig.

#69

)

"@"

for the rewinding

.

This is the actual upper loop formin

g position. When turning the function

switch from "STOP" to "MIC", the upper loop forming guide roller kick

s

upward to form the enough upper loop.

As keep turning the function switch to "MIC' (o

r

fj)

,

«

)

positions, the

roller comes down and stays at this position "C", rea

dy to activate th

e
"Film Guard" switch should the upper loop be lost.
Note the distance between the top edge of the upper loop guide bracket till

the projector's chassis is approximately 13mm.

Position D: When the upper loop is lost due to the bad film with a series of damaged
(Fig. #72) perforations by more than about 6 frames, .the loop forming guide roller i

s

pulle

d by the film and moves to this position "D".

As the roller moves to this position, the film guard is activated a

t the same

tim

e and shuts off the power, stopping the projection to protec

t the

film

from the further damage

.

To re-start the projection, tu

rn the function switch to "STOP", then back

(4) Make sure the convex mount on the end of the # 1 sprocket shoe is seated in th

e

slot of the upper loop arm (1 ). (Fig. #74)

(5) The tip of th

e arm (9) shoul

d be seated on the plate spring (14) as Fig. #75

.

In the event of the incorrect position as Fig.#79\thefollowing troubles ma

y be expected

;

(1) When the function switch is slowly turned.from "MIC" to "STOP", the arm tip wil

l

not stop at the position as Fig. #75 and slip over to the position as Fig. #76 which

means the upper loop forming guide roller is at its top position as Fig. #70

.

Consequently,

(2) The upper loop is not formed correctly

.

(3) In "Rewind" the film may be in contact with the parts in the film path

.

(4) The upper loop formin

g guide roller exceeds over the top of the lens holder cove

r

and the film may not be loaded smoothly.

Note (2)

The arm tip should not be positioned below th

e curve

d point on the plate spring as
Fig. #80.
In the event of the incorrect position as Fig. #80 the following t

roubles may be ex

-

pected

;

(1) Th

e arm tip will not slide on the plate spring to the position as Fig. #76 which

means the upper loop forming guide roller does not move to its top position as Fig.#70

.

(2) The upper loop is not formed correctly

.

(3) Th

e activation of the film guard switch will delay resulting in the switch not activat-

ing with the six frames consecutive film damage.

Note (3)

The proper clearance between the film guard arm and the film guard switch shoulder i

s

required. If being too close or with no clearance, the arm tip may stick fast and will no

t

rotate resulting in the switch not activating. To adjust, re-mount the switch swingin

g

clockwise so that the maximum clearance is obtained as Fig. #81.

-

b. To adjust, se

t the

function control to "STOP", loosen the two mounting screws, rotat

e

the function control to "MIC". Th

e film shoe should be seated flat against the aperture

plate, at the sa

me time it is aligned with the outer guide rail. Secure the mounting screws,

open and close the gate, and re-check the position of the film shoe

.

c. Load up a film and check for even focus. If necessary, refer to the section on uneve

n

focus.

4. Retraction of the Cam Cla

w

a. In the "STOP" or load position the cam claw is retracted by the action of the # 1

sprocket shoe interlocking bracke

t.

b. Incorrect alignment of the cam claw retraction mechanism will result in some type of

abnormal noise during forward or rewind without film.

(1) "Rewind": If the claw does not clear the shutter, locate the bent shutter blad

e

and re-form to clear the claw.

(2) "Forward": Check the position of the reception arm as described in Sec. 6-4-B-1-b.

5. Lower Loop Forming Mechanism
Refer to section 322-6-3 Lower Loop Setter System.

To check for correct adjustment of the loop setter roller, load a film and observe that th

e

film is not in contact with the film shoe, aperture plate, rubber rollers, s

ound drum, an

d

solar cell case

.

6. Buzz Roller Tension and Position (Fig. #83

)

a. Durin

g normal projection the buzz roller (19) firmly holds the film against the sound

drum by the tension of spring (25)

.

b. The position of the buzz roller and its tension is critical for minimum wow and flutter

.

In "STOP" and "REWIND" it must be clear from the film path. It is also important tha

t

there is no end play. The end play of the buzz roller will cause variable or poor soun

d

trackinz

.

tension roller should ride on the film with gentle tension. A slight pu

sh on the roller

should allow it to travel downward slightly. In "REWIND" the roller is raised up by the

interlocking bracket to clear the

film path

.

d. Adjustment: To adjus

t the tension roller's position, remove the control pannel and turn

function switch to "MIC" to expose the nut (4mm) from behind th

e interlockin

g

bracket. (See Fig. #89

)

Fig. #89

Unhook the tension spring and using a 7mm nut driver, loosen the 4mm nut slightl

y

a

nd retu

rn the function switch to "STOP".

(1) Bring the tension roller close to the No. 2 sprocket shoe roller keeping approxi

-

mately 0.5mm gap.

(2) Tu

rn the rotary switch to "MIC" holding the tension roller in the position

.

(3) Tight

en the 4mm nu

t.

(4) Hook up the tension spring

.

(5) Make sure the tension roller position is correct at "STOP" "MIC" "REWIND".

e. Another method using the El Kl (185-01211) adjustment gauge

-

(1) Se

t the function switch to "MIC" and slightly loosen the 4mm nut as shown in

Fig. Fig. #89.

(2) Insert the El Kl tension roller gauge.(185-01211) (F[g. #90, #91

)

(3) Push the tension roller down against the gauge. {18.8mm

)

(4) Holding the tension roller, tighten the 4mm nu

t.

(5) Remove the gaug

e and check the rollers position in "STOP" "MIC" and "REWIND"

.

f. The tension spring may be adjusted by slightly stretching if n

ecessary t

o minimize wow

and flutter. A weak spring should be replaced. A properly adjusted tension roller should

ride in the middle of it's travel.

8. #2 Sprocket Shoe Adjustment

REWIND SYSTE

M

- 64

-

A. Description

In the rewind function, the film path is opened allowing the

film only to contac

t the

four

film guide rollers. At the same time the rewind control ar

m moves the rewin

d drive gear (14)

towards the opposite mating driven gear (22) which in tu

rn drives the set collar (19) via a

cork clutc

h plate which drives the pulley shaft, arm belt and arm spindle assy. When the driv

e

gears are engaged, the function control switches th

e motor's direction and energizes the main

drive motor.

The large drive gear tension spring (15) provides the tension keeping the drive gears A (14)

&

B (22) from engaging during forward. The smaller back tension spring (17) maintains a small
amount of back tension to the supply reel. The rewind spring (24) sets up the rewind clutch
tension by supplying pressure to the sleeve plate (23) the cork clutch liners (21) which in
turn transmits the rewind drive from drive gear A to Band to the drive pulley shaft, belt and
spindle. (Fig. #93)

B. Adjustments

1. Rewind Mechanism
A 0.5mm clearance between the two mating drive gears is critical

for correct rewind

engagemen

t. This distance is maintained by fiber washers as indicated, adding or subtract-

ing washers as may be necessary to accomplish the desired clearance. T

oo much clearance

will result in improper mating of the gears and will damage the gears. Too close a clearanc

e

will cause the gears to contact in forward, resulting in abnormal gear wear and noise. With

the correct fiber washers the clutch springs should be compressed with the set colla

r

pushed all the way towards drive gear A and secured with the set screw

. (Fig. #95)

2. Rewind Spring Adjustmen

t

The knurled nut (25) adjusts the rewind torque. Excessive rewind torque will cause the

motor belt to slip when rewinding a large full reel; too little rewind torque will not rewin

d

a large 2000' ree

l. The correct adjustment must reduce the space between the clutch hub

and knurled nut t

o be less than the thickness of the adjusting spring.

SOUND DRUM AN

D FLYWHEE

L

A. Description

The sound drum and flywheel assembly's main function is to stabilize the film, allowing the

sound optics or magnetic head to read the sound tracks with a minimum of speed variations.
The sound drum, shaft, bearing and flywheel are precision machined and balanced to main-
tain a consistent linear film speed. Care should be used when disassembling or re-assembling
these precision parts

.
The sound drum shaft (46) is seated in two precision ball bearings (48) which are sealed and
factory lubricated. The ba

ll bearings are lightly press fitted into the sound hub casting (47).

The shaft is secured in place

by a set collar (51

). With the fiber washer in place, with no end

play in the sound drum shaft, it must rotate freely and not bind. Any binding or imper

fec

-

tions in the ball bearing will result in excessive wow

&

flutter. In the forward direction, th

e

sound drum shaft (46) is driven by the tension of the

film. The flywheel is fr

ee to slip on th

e

soun

d drum shaft during the initial start u

p o

f the projector t

o prevent any possible

film

damage. The flywheel brake mounted on the main interlocking bracket stops the rotation o

f
the flywheel instantly when the function switch is turned to "STOP" so that the film is not
scratched by the sound drum which intends to keep turning. During projection the brake is
o

ff away from the flywhee

l. (Fig. #97

)

B. Adjustments

The ba

ll bearings are li

fe time lubricated and lightly presses into the hub (47). The amount o

f

shaft (46) end play should not exceed 0.2mm a

nd is determined by the set collar's (51) posi

-

tion. Care should be take

n not to bend the shaft or lubricate the bearings. (Bearings ar

e
factory lubricated and should be replaced if defective). Defective or incorrect lubrication of
the bearings wi

ll result in excessive wow and flutter. The plate spring (54) tension may b

e
adjusted for minimum wo

w and flutter with the screw secured

. Whenever removing the spring

and flywheel is necessary, care should be taken to avoid changing the plate spring

's tension.
