3.3. ELECTRICAL CONNECTIONS
Before wiring the projector, refer to Figure 3-3 for the wiring interface diagram. Use stranded wire. Strip and tin the wire prior to connection. Use crimp connectors on all sound connections. For projectors equipped with an automatic turret, refer to Section 6.6.3.
3 . 3 . 1 . SO L A R CE L L W I R I N G
Solar cell wiring requires a shielded, four-conductor audio cable. (red – left (+), black – left (-), green – right (+), white – right (-)). The best signal-to-noise ratio is achieved by maintaining the same ground potential between the sound-head and the cinema processor. Refer to the directions in the sound system instruction manual for proper connection of the sound system.

4. OPERATING THE PROJECTOR
4.1. GENERAL
Before operating the projector, verify that all phases of installation and assembly have been completed.
•Verify that cover for belt side of projector is installed before and during operation.
•Do not make adjustments on belt side of projector while cover is removed or power is on.
WARNING • Do not make adjustments or perform maintenance on projector while it is in operation.
4.2. PRE-OPERATING PROCEDURES
4 . 2 . 1 . FL Y W H E E L I N S T A L L A T I O N
1.Back out flywheel set screw far enough to let flywheel slide onto shaft without scoring shaft or damaging threads on set screw.
2.Slide flywheel onto shaft until it stops.
3.Position set screw over flat portion of shaft and tighten set screw.
4.Spin flywheel by hand to check for smooth operation.
CHRISTIE recommends that any projector accessories be installed at this time.
4 . 2 . 2 . TU R R E T I N S T A L L A T I O N
1.Secure turret hinge plate with four Allen head screws.
2.Install turret latch assembly using same holes and hardware (if it is not already installed).
3.Connect turret wiring to TB4-1 (Red) and TB4-2 (Black).

3.Install lens system in lens holder. If it is necessary to open lens holder wider than normal:
a)Loosen two lens-locking screws.
b)Turn jack screw clockwise until lens slides into lens holder.
3. Set focus knob at mid-position.
3. Secure lens system with two locking screws.
Over-tightening can cause focus mechanism to bind.
4.3. FILM THREADING AND OPERATING PROCEDURE
Refer to Figure 4-1 for film threading and positioning.
1.Set Ultramittent to its rest position. There should be no sprocket movement when manual turndown knob (N) is turned.
2.Center framing knob (P) by aligning mark on knob with line on projector housing marked
CENTER FRAME.
3.Swing out pad rollers (B, F, and L) on upper constant-speed sprocket assembly (A), center constant-speed sprocket assembly (G), and lower constant-speed sprocket assembly (M).
4.Swing out film shoe on Ultramittent assembly (E).
5.Pull out catch knob (D) and swing out trap and gate assembly (C).
6.Using slightly more film length than is required to reach film transport system, begin to thread film into projector.
7.Align film on Ultramittent sprocket and close Ultramittent film shoe.
8.To form proper loop between Ultramittent and center constant-speed sprocket assembly:
a)Pull film loosely over pad roller while pad roller is in open position (R) and then onto center constant-speed sprocket.
b)Mate film sprocket holes with sprocket roller pins.
c)Hold film in position and close pad roller.
The required film loop has now been formed.
9.Thread film on sound-head assembly as shown in Figure 4-1:
a)Holding two lateral guide rollers (H and K) towards each other, pull film tight and align film on lower constant-speed sprocket assembly (M).
b)Tighten film on one sprocket hole so lateral guides barely float off sound drum.

10.Place film at upper part of Ultramittent in film guide (R).
11.Align film on steel bands of trap and gate assembly (T).
12.Close gate (C) and lock catch knob (D) in place.
13.Form 1.5-inch loop between upper constant-speed sprocket and gate (C), as shown in Figure 4-1.
14.Align the film on upper constant-speed sprocket (A) and close film shoe (B).
15.To verify that film is correctly aligned on all sprocket rollers, move turndown knob (N) clockwise.
•Framing lamp can be turned “on” or “off” with black rocker switch located on top of projector.
•Framing lamp is functional with picture changeover in either position.
•If film reel is used, be sure take-up tension is in accordance with reel manufacturer’s instructions.

5.2. VISUAL INSPECTION
1.Visually inspect projector for signs of excessive dust, dirt, physical damage, frayed or damaged cables, and loose hardware.
2.Remove, replace, and repair as necessary.
3.Visually inspect inner, outer, and shutter timing belts. Replace belts that are frayed or show signs of wear.
4.Check belt deflection (Sections 6.4.1, 6.4.2, and 6.4.3) and re-adjust if necessary.
Ultramittent should be visually checked every 30 days. If leak is detected, contact CHRISTIE to arrange for loan of substitute
Ultramittent. If leak is very slow, you may continue to operate Ultramittent for 30 to 90 days.
