l-1: INTRODUCTION
The El Kl
"N" series se lf-threading prolector is very
similar to the earlier
"R" s€ries model with added
improvements such assilent threading, flet response
amplifier, lighter weight, etc. With few exceptions,
zuch as color, most parts from the
"N" series
substitute direetly into the previous
"R" sries'
This manual also covers the NT manual threading
models when excluding the sections on the thread-
ing mechanism.
I.2: IIilECHANTCAL SYSTEM
The ElKl Self-threading proiector is contrclled by
a single function switch for forward, reverse and
high-low lamp positicns.
A. T.HEEAD!_\!_Q:
Threading is accomplished by s€tting the
threading guide lever to thread' function
switch to forward and inserting the fitm
i*to the threading channel- The threading
mechanism is automatically released and
engages the claw by a light tug of the film
when attaching ir to the take-up reel.

Advance the switch from forward to lamp
low or high,

To reverse the projector, return the function
switch to
"OFF" and then to reverse and
lamp.
D . R E W I N D :
To reivindthefilrn,engage the rewind lever.
Attach the film to the empty supply reel
and advance the function switch tc
"For-
ward".
1-3: ELECTRICAL SYSTEM
[lKl "N" series projectors are available in voltages
of 100V, I
'l0V,
1 20V, 2?0V and ?40V. 1 1 0/220V
and 120124fiV dual voltage models ars also avaifable.
To comply with electrical safety regulations of
various countries, UL (USA), CSA {Canada), VDE
{Germany), SEV (Switzerland), SAA (Australia},
SEMKO {Sweden}, NEMKO {Norwav), FEMKO
(Finland), DEMK0 (Denmark), specific models are
manufactured to meet such regulations, inclqding
the opticn of 50H2, 60H2, 50/60H2 operation-
Power transftrrmerg vzry aceordang to the voltage
range and also to the various electrical safety
requirements. The secondary windings of all trans-
formers provide 8V AC to the Pilot Lamp and
Exciter Lamp circuits, 24V AC (HIGH) and 22V
AC {LOW} to the Halogen Prciection Lamp and
40V or 36V AC to the AmPlifier.
{See Sec. +4 TRANSFORMER MODULE).
Motor OFUOFF and Lamp ON/OFF and reverse
is controlled by the Function Switch which consists
of a Cam and 5 micro switches.
The proiection lamp b a Halogcn ELC type 24V
250 watt- The
"High-Lorv" position wilt extend
the lamp life,depending upon operating corditions.
NOTE
: The Hatogen LamP EtL tYPe 24V
200W maY also be uscd with some
reduction in light outPut.
The motor is an induction type with capacitor.
Motors are available for all the voltage ranges
above. Optional Synchronoul motor kits are also
available for precise film spcedr and tele+ine
conversions,
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 reguirements of the countries listed'
1-4: SOUND SYSTEM
ElKl "N" series models are designated according to
the sound playback and record capabilities with or
without front cover extension speakers.
Optical Playback only: Model NST-O' -l
