Lens Turret
The MANUAL lens turret requires no electrical connections. Installer connections to the AUTO-
MATIC turret are made to the J4 terminals located on the printed circuit board on the control box door adjacent
to the gear compartment cover on the side of the projector. The inputs
(FEED, SPECIAL, FLAT,
and
SCOPE
)
are derived from an automation controller and/or other installer-supplied circuitry. NOTE:
“SPECIAL”
input
applies only to a
third
lens in a three-lens turret.
LENS INSTALLATION
The lens barrels are individually marked to designate their screen format. The barrels of the standard
two-lens turret are marked SCOPE (CinemaScope, or anamorphic) and FLAT (“wide screen,” or non-
anamorphic). Lens barrels on the three-lens turret are marked SC (CinemaScope), FL (Flat), and SP (Special).
The lenses must be installed in their designated barrels for correct aperture logic. Magnacom lenses are not
required in any configuration.
Rotate the turret to the SCOPE position. The automatic turret can be indexed to this position by pressing
the reset switch; the manual turret must be indexed by hand. Make certain the SCOPE aperture plate is in
position. Center the focus adjustment screw, allowing equal travel forward and back. Insert the CinemaScope
lens and anamorphic adapter into the SCOPE barrel. Start the projector, ignite the lamphouse, and project
a picture to the screen. Move the lens inside the barrel until a sharply focused picture is projected, and rotate
the lens and adapter to set the anamorphic correction on the horizontal plane. Securely tighten the lens locking
knob on the top of the SCOPE barrel. Close the lamphouse douser.
Reset the turret to FLAT format, and make certain the FLAT aperture is in position. Install the FLAT
lens, and center its focus adjustment screw. Open the lamphouse douser and move the lens inside the barrel
until a sharply focused picture is projected. Tighten the lens locking knob above the FLAT barrel.
Repeat the above procedures as required for the “special” lens used in a three-lens turret. Once
installed, DO NOT remove the lenses for cleaning. The turret is hinged, and opens to permit cleaning the rear
surfaces of the lenses.
File the aperture plates to size the picture to the screen and/or masking. NOTE: When projecting a
white light while filing apertures, close the lamphouse douser
frequently
to allow the lens to cool.
DO NOT attempt to correct “keystoning” by shimming the turret or offsetting the position of the lenses.
The lenses
must
be positioned on optical center to project an acceptable image.
SOUND READER FLYWHEEL INSTALLATION
The sound reader flywheel is dismounted for
shipping to avoid damage to the impedance drum shaft.
Assemble the flywheel to the end of the impedance drum
shaft using the wave spring washer and spacer in the
sequence shown (spring washer against the flywheel,
spacer next to bearing seal). Secure the flywheel to the
shaft with the 1/4 inch hex head screw. Note
LEFT-
HAND THREAD;
turn
counterclockwise
to tighten.
