GENERAL MAINTENANCE
1 . 1 CLEANING
Exterior surfaces of the viewing table are in most cases, enamel
or lacquer painted aluminum with stainless steel and anodized aluminum
fittings. Clean with a damp cloth and if necessary, a mild detergent.
The glass viewing surface and film rollers should be cleaned with warm
water and a mild detergent daily or more often if required.
The film carriage support rods (Figure 2-1 (13)) should be kept
free of dust and dirt to insure smooth operation of the film carriage.
All screened and slotted vent holes in the viewing assembly and
base assembly must be kept free of any dust or lint to allow adequate
cooling of electrical components.
The inlet filter screen to the cooling air blower (Figure 2-2 (1))
located on the lower surface of the viewing assembly should be visually
Inspected daily depending on operational environment. Check for any
obstruction that might decrease the air flow. The screen may be cleaned
by manually brushing off any foreign matter.
1.2 LUBRICATION

1.2.2 Lower Light Box Assembly (Figure 2-4)
1) Manual film transport drive chain. At approximately 6 month
intervals the chain mechanism should be lubricated with a good grade of
light machine oil. Lubricate all chain roller and sprocket bearings.
Roller chain should not be dry but should be lubricated very sparingly.
All handwheel shafts have grease packed ball type bearings.
1.2.3 Motor Drive Housings (Figure 2-3 (6 & 9))
At approximately 6 month intervals lubricate the gear and
sprocket jack shaft bearings, clutch rotor bearing, clutch armature
bearing and the tach-generator bracket bearings. These bearings are all
oil impregnated bushing type and require very little lubrication. The
motor and clutch shaft support bearings are grease packed and require
no lubrication. The tracking adjustment knob and mechanism will only
require lubrication if it becomes hard to turn. Use Jet-Lube AP1 or
MIL-G-32 78 grease or equivalent.
1.2.4 Base Box Assembly (Figure 2-6)
The worm and worm gear on the tilt drive mechanism should be
lubricated at 6 month intervals or oftener, depending on amount of use.
Use Jet-Lube AP1 or MIL-G-3278 grease or equivalent. Apply a light
machine oil to the worm thrust bearings, shaft support bearing and tilt
plate hinge pins.

SECTION 2
FUNCTIONAL DESCRIPTION
2.1 GENERAL
The Advanced Light Table is a stable portable film viewing
platform for photo interpretation operations. The viewing table will
transport 500 ft spools of film in various widths of 9-1/2 inches through
70mm, both manually and by motor drive. The film may be transported
at slewing speed for rapid rewind or at slow scanning speeds for photo
Interpretation. The viewing assembly may be tilted electrically from
horizontal through 75? and rotated manually CCW through 900 for short
axis viewing. The table consists of three basic sections (Figure 2-1):
Upper light box assembly, lower light box assembly and the base box
assembly.
2.2 UPPER LIGHT BOX ASSEMBLY
The upper light box assembly consists of the cold cathode
lamp grid with reflector, diffuser and viewing glass, the shade assembly
with it's operating mechanism and the upper control panel. Access to
the bottom of the upper light box which is hinged to the lower light box
can be obtained by the loosening of two hold down screws in the front
corners of the upper control panel (Figure 2-1 (30)). For removal of the
upper light box assembly see paragraph 6.1.
I) Lamp Grid Assembly. The lamp grid (1,1) and reflector
will be treateu as one assembly for removal, replacement and maintenance.
For removal of this assembly see paragraph 6.4.

M-105-69
2) Shade Assembly. The shade assembly is a manually
operated mechanism consisting of a roller with shade, bead chain and
sprocket drive and operating control wheel. The operating control wheel
(Figure 2-1 (29)) is on the left of the upper control panel. The lamp grid
assembly will have to be removed for access to the shade mechanism.
3) Upper Control Panel. The upper control panel consists of
the light intensity control (potentiometer R6 Figure 2-3 (3)), film tension
control (switch S2 Figure 2-3 (2)) and the film direction/speed control
(potentiometers R3, R4 and R5 Figure 2-3 (1)). The electrical components
are easily removed and replaced.
2.3 LOWER LIGHT BOX ASSEMBLY
The lower light box assembly supports through a hinge and
two attachment screws, the upper light box assembly. The lower light
box assembly consists of electrical components, manual handwheel drive
mechanism and reversing switch, film spool motor drive housings, film
spool support carriages and rods, film rollers, front control panel, and
rotary Joint with interconnecting rings.
2.3.1 Electrical Components (Refer to Wiring Diagram Figure 5-1)
1) Circuit Boards. There are 3 circuit boards as follows:
Viewing light dimming (Figure 2-4 (10)), film transport logic and control
(Figure 2-4 (17)) and film spool drive motor (Figure 2-4 (16)). These
circuit boards will be removed and replaced for field maintenance (see
paragraph 6.11). The basic function is described by their title.
2) Motor Capacitors Cl, C2, C3, C4 (see Figure 2-5 (2)).
Remove and replace for field maintenance.

M-105-69
3) Cooling Air Blower B4 (Figure 2-4 (8)). The cooling air
blower pulls air, in through the filter in the boctom of the lower light box
and forces it into the slots in the light grid reflector and subsequently
out through slots in the sides of the upper light box.
4) Manual Transport Reversing Switch S6 (Figure 2-4 (19)).
This reversing switch senses the direction of rotation of the handwheels
through a shaft mounted slip clutch (Figure 2-4 (20)) and imparts this
Information to the logic and control circuit board.
5) Terminal Blocks (Figure 2-4). The terminal blocks
designated TB-2, -3, -4, -5 and -6 are designated and located in the
lower light box assembly. For function see Wiring Diagram (Figure 5-1).
6) For other miscellaneous electrical components and their
description see Wiring Diagram (Figure 5-1).
2.3.2 Manual Handwheel Film Drive Mechanism (Figure 2-5)
The manual handwheel film drive mechanism consists of 2
mechanical circuits driven by chain and connected through electrical
clutches. The 3 handwheels are all connected by chain through a series
of sprockets, idlers and shafts to form the first circuit. When any
handwheel is rotated CW or CCW the other handwheels follow and also
operate the manual transport reversing switch (paragraph 2 .3.1 (4)) the
second circuit connects both LH and RH film drive motor housings
(Figure 2-5) through a series of sprockets and idlers. This circuit is
driven by the first circuit through two electrically actuated clutches
CL3 (LH) arid CL4 (RET). These clutches are only used during manual
transport operation and when de-energized disconnect the handwheel
circuit.

2.3.3 Film Spool Drive Motor Housings (Figure 2-3 (6)). The film
spool drive motor housing assemblies LH and RH are identical in operation
and configuration. The drive assembly consists of a sprocket and gear
jack shaft assembly, direct drive DC torque motor, electrically actuated
clutch, motor armature and clutch supporting shaft with bearings, film
spool drive spindle, tach-generator with belt drive system, film loading
control and tracking mechanism.
1) Sprocket and Gear Shaft Assembly. The sprocket is part
of the second circuit in paragraph 2.3.2 and connects this circuit to
the armature and clutch shaft through a spur gear set and electrical
clutches (CL1 and CL2). The mating spur gear is part of the clutch
? armature and only rotates when the clutch is energized during manual
transport operation.
2) Direct Drive DC Torque Motor. The torque motor consists
of 3 parts: super-saturated permanent magnet field assembly, armature
assembly and brush rigging. The field assembly with brush rigging is
fixed to the drive housing. The armature assembly is part of the
armature and clutch support shaft. The motor supplies torque through
the film spool drive spindle either for hold back tension or film spool
drive.
3) Electrically Actuated Clutch. The clutch is energized
during the manual transport operation and connects the clutch armature
(with spur gear) through the clutch rotor to the support shaft and film
spool drive spindle. The clutch is de-energized during the power mode
of film transport operation. The tach-generator first stage drive pulley
is assembled to the clutch rotor.

4) Motor armature and clutch supporting shaft with bearings.
The shaft assembly supports the motor armature and electrical clutch.
The shaft rotates during manual and power drive transport operation.
5) Film Spool Drive Spindle. This spindle is inside the
support shaft and is rotated by it through drive pins. The spindle is
moved axially for film tracking by rotation of the tracking knob.
6) Tach-generator. The tach-generator is mounted to the
drive housing and is driven through a 2 stage pulley and belt system
connected to the clutch rotor. The tach-generator supplies a feedback
signal to the control and logic circuit board, which is relative to the
film drive motor speed.
7) Film Loading Control S4 and 55 (Figure 2-1 (19)). The film
loading control is a manually operated 2 position electrical switch.
This switch selects through the logic and motor control circuits the film
loading sequence desired or more specifically the rotation of the film
drive spindle. During the "power" mode for film transport the switch
obtains desired film loading by electrically reversing the motor
direction. During the "manual" or "off" mode for manual operation of
the film transport the switch obtains the desired film loading by selecting
the electrical circuit which will energize the correct sequence of
electrical clutches.
8) Tracking Mechanism. The tracking knob by rotation will
move the film spool drive spindle and consequently the film spool at
right angles to the film direction for correction of any misalignment.
A pin moving circumferentially when the knob is rotated travels in a
spiral groove in a bushing that will only move axially. As the knob is
rotated and the bushing moves axially it in turn, displaces the drive
spindle.

2.3.4 Film Spool Support Carriage (Figure 2-1 (1))
The film spool support carriage is movable along guide rods to
adjust to and support various widths of 500 ft film spools. It has a free
rotating spindle to mate with the film spool. A spring loaded detent
locks the carriage in position by engaging notches in the rods. The
carriage is spring loaded toward the motor drive housing with a "negator"
type spring motor contained in the carriage housing.
2.3.5 Film Rollers (Figure 2-1 (2))
The film rollers consist of a hard anodized aluminum tube
supported by teflon impregnated plastic bearings and running on a
corrosion resistant steel shaft. The rollers are easily removed or installed
by lifting out or inserting into the roller shaft supports. The rollers are
aligned by adjusting the roller shaft support on the motor drive housing.
2.3.6 Front Control Panel (Figures' 21 and 2-5)
The front control panel contains the following controls: power
tension adjustment control, manual tension adjustment control, main
power switch and the rotational lock lever.
1) Power Tension Adjustment Control (R1). Rotation of this
potentiometer controls film tension in the "power" mode by applying reverse
motor torque to the film spool drive opposite to the spool being driven.
2) Manual Tension Adjustment Control (R2). Rotation of this
potentiometer controls film tension in the "manual" mode by applying
reverse motor torque to the film spool drive opposite to the spool being
driven.

3) Main Power Switch Si (Figure 2-1 (24) and 2-5 (6)). The
main power switch is a push "On", push "Off" type switch to connect line
power to the light table circuits.
4) Rotational Lock Lever (Figure 2-1 (26)). The rotational lock
lever is a manually operated lever that detents the viewing assembly
with the base tilt plate in the two table positions of rotation (long axis
and short axis). "Unlock" for rotation by lifting up and "lock" by pushing
down.
2.3.7 Rotary joint and Interconnecting Rings (Figures 2-2 (6) and 2-5 (9))
The viewing assembly is connected to the base box assembly by
a rotary joint and interconnecting rings. The joint and rings tie the
bottom of the lower light box assembly to the tilt plate on the base box
assembly. The rotary joint bushing passes through the lower viewing
box, Delrin spacer washers, the tilt plate and is secured by the bushing
nut. The rotational friction can be set by the adjustment of this nut.
The nut is locked by a nylon set screw. A bracket attached to the tilt
plate and inserted into the bushing prevents rotation of the bushing.
Electrical wiring from the base assembly to the viewing assembly passes
through this protective bushing. The rings are interlocked to each other
and provide stability with the base during rotation and tilting operations.
2.4 BASE BOX ASSEMBLY (FIGURE 2-5)
The base box assembly is made up of the following: tilt plate
with hinges, tilt drive mechanism and electrical components.

2.4.1 Tilt Plate With Hinges
The tilt plate supports the viewing assembly and is hinged to
the base box. The tilt plate is driven electrically through the hinge
assembly, by the tilt drive mechanism.
2.4.2 Tilt Drive Mechanism
The electrically driven tilt mechanism consists of an electric
motor with gear box, slip clutch, worms, worm gears, pulleys and
timing belts. The electric motor is energized by an electrical switch
on the right side of the base at the front (Figure 2-6 (20)). The motor-
gear box drives the worm and worm gear through a slip clutch. The slip
clutch will slip when the viewing assembly reaches it's tilting or
horizontal limit. Mechanical stops on the hinge assembly limit the light
viewing assembly travel to 75? of tilt.
2.4.3 Electrical Components (Figure 2-5)
The electrical components in the base assembly are: power
cord receptacle (P2), 15 amp fuse and fuse holder (Psi), power transformer
(T1), lamp grid transformers (T2, T3, T4), tilt switch (33), terminal
blocks (TB1 and TB-3), tilt drive motor with gear box (B3) and miscellaneous
components as shown in wiring diagram.
