PREFACE

THE STRONG “575” FOLLOW SPOTLIGHT Model 41000 is an AC follow spot complete with lamphouse, igniter, power supply, optical system, and color boomerang. It is designed for use with the 575 watt metal halide bulb, Strong part number 41102.

THE “575” LAMPHOUSE has a deep ellipse cold-coated metal reflector designed to operate in a fixed position, with the bulb mounted horizontally in the lamphouse. The bulb is adjustable in relation to the reflector to permit positioning on the reflector optical center line. The igniter is contained in the base of the lamphousing.

THE SEPARATE POWER SUPPLY comes equipped with a three-wire AC line cord terminating in a 125 volt (±10 volt), 60 Hz. plug that can be connected to an AC outlet, and draws approximately 7 amperes from the line. The power supply also has two switches and a toggle type circuit breaker. The circuit breaker must be in the “ON” or “RESET” position to energize the power supply. The two switches are an “ON” switch and “OFF” switch. The lamp may be turned on or off by use of the appropriate switch at the power supply or at the lamphouse.

THE IGNITER in the lamphouse requires a 237 V.AC open circuit pulse, provided by a step-up transformer in the power supply, to ignite the bulb. After ignition, the power supply automatically drops the voltage to the value required to maintain the arc.

THE ADJUSTMENT CONTROL for positioning the metal halide bulb is located behind the cover panel at the rear of the lamphouse. This control mechanism permits focus adjustment of the bulb in relation to the reflector and also allows the bulb to be centered both vertically and horizontally on the optical center of the reflector.

THE LAMPHOUSE has a running time meter to indicate the number of hours the bulb has been used. It also has two switches for the “ON” and “OFF” control at the lamphouse. The lamp can be controlled from either the power supply or the lamphouse. To break the AC supply at the power supply and lamphouse, open the circuit breaker on the rear of the power supply.

THE POWER SUPPLY is attached to the lamphouse by a cable assembly approximately

13 feet long, terminating in an MS connector for easy attachment to the lamphouse. This cable assembly contains all the control wires for the operation of the lamphouse and power supply.

TWO BLOWERS are used in the follow spot system and operate from the 115 volt AC supply only while the bulb is ignited. One blower is used to cool the lamphouse and bulb; the other, in the lens mechanism, cools the color gels and lens system.

SETTING UP SPOTLIGHT

THE “575” FOLLOW SPOT is shipped in sections which must be assembled.

ASSEMBLE the four base legs to the square section of the center tube, using the 3/8-16 by 2-3/4 inch hex head cap screws and 3/8 inch split ring lockwashers to secure each leg. Insert a leveling foot and locknut in each of the four legs.

THE INNER TUBE and support yoke has four holes on four-inch centers and will allow an optical center height of approximately 46-1/2 inches, 50-1/2 inches, 54-1/2 inches and 58-1/2 inches above floor level to the optical center of the lamphouse and lens system. The leveling feet may be adjusted through a two inch range. Insert the height location pin through the hole in the outer tube and one of the holes in the inner tube so the retaining ball on the pin extends beyond the outer tube.

THE VERTICAL TILT locking lever is on the right hand (operating) side of the yoke assembly. Tighten this locking device securely before attempting to place the lamphouse and lens mechanism on the support yoke.

PLACE THE LAMPHOUSE and lens mechanism on the yoke assembly, with the lens control knob to the right hand (operator’s side); the same as the locking lever on the yoke. Line up the four mounting holes in the bottom of the lamphouse and optical system support pan with four slotted holes in the support saddle and secure with the four 5/16-18 wing screws. Release the vertical tilt locking lever, move the lamphouse and optical system forward or back in the slots until the system is balanced. Then tighten the four wing screws to hold the system in balance.

CONNECT THE CABLE ASSEMBLY from the power supply to the mating receptacle on the bottom of the lamphouse and tighten firmly. The connector and receptacle are keyed to prevent misalignment of the pins. Do not connect the power supply to the AC supply at this time.

THE FOUR ANGLE BRACKETS on the base legs are designed as hold-down brackets for the spotlight. These brackets should be bolted to the floor or platform for safety purposes. The casters are provided only for ease of movement to the operating location and must be removed from the base legs to ensure stability during use of the follow spot.

WHEN TRANSPORTING or hoisting the follow spot, DO NOT ATTEMPT TO LIFT the complete system, including the stand, by raising the lamphouse and lens mechanism. The most simple procedure is to release the tilt locking lever, and the hex head screw and nut on the opposite side, just enough to permit lifting the lamphouse and support saddle from the yoke on the stand. Then transport as two separate assemblies.

575/004

BULB INSTALLATION AND OPERATION

REMOVE THE REAR COVER PLATE by pulling on the center section of the three retaining pins to release the plate. This will provide an opening to grasp when removing the lamp housing. Tighten securely the vertical tilt locking lever on the yoke. Remove the six screws attaching the housing to the base and loosen the one at top and front of the house. Slide the housing back and off the base for easy access to the bulb support.

ASSEMBLE THE BULB before installing it in the lamphouse. Keep fingers off quartz envelope. Remove the two knurled nuts from both ends of the bulb. Screw the front bulb extension

(Part No. 41116) on the end of the bulb which has the evacuation or seal tip. This will place the seal away from the reflector and towards the front of the lamphouse. The best light is obtained with the envelope seal tip to the front of the lamphouse. Place the terminal on the end of the front bulb lead (with the banana plug) against the end of the bulb extension #41116. Use one of the knurled nuts to secure the lead to the extension. Make sure the connections are tight, being careful not to put any strain or finger prints on the bulb envelope. The other knurled nut is not required; keep it for future use if needed.

PLACE THE END of the bulb without the lead through the center hole in the reflector, into the rear support collet. Loosen the small allen head screw in the collet so the metal end cap of the bulb can be fully inserted into the collet. Tighten the set screw firmly against the bulb’s end cap to ensure a good electrical contact.

THE OTHER END of the bulb (with the extension and lead) must be positioned so it will seat at the bottom and center of the “ Y ” in the front support yoke. Insert the banana plug into the receptacle on the air duct.

SLIDE THE HOUSING back onto the base; note the sides of the housing should be inserted into the slots on the base. Do not replace the rear cover plate until the bulb alignment procedure

(following) has been completed. Slide the cover under the top screw and replace the six screws along the bottom of the housing.

PLUG THE AC LEAD CORD from the power supply into any grounded three-wire, 15 ampere, 120 volt outlet. Set the circuit breaker on the rear of the power supply case to the “ON” or

“RESET” position. Press the green “ON” switch at either the power supply or at the lamphouse and the bulb will ignite.

ALLOW THE BULB to heat up for two or three minutes to reach full brightness, then proceed with the following instructions for alignment of the bulb with the reflector.

575/005

BULB INSTALLATION AND OPERATION(continued)

THE CENTER SECTION of the control is a threaded member that focuses the bulb in relation to the reflector. Turning this adjustment moves the bulb along the optical centerline of the reflector. Turning this section clockwise moves the bulb away from the reflector. The small knurled screw to the left of this section can be tightened to lock the focusing mechanism, after the following procedures have been completed.

THE THUMB SCREWS on either side of the focusing control lock the horizontal and vertical adjustment mechanism in position.

TO FOCUS THE METAL HALIDE BULB and obtain the best light on the stage the method outlined below is the most suitable.

MOVE THE SPOT SIZE CONTROL handle on the large lens carriage all the way forward to project the smallest spot possible, with the iris, the masking shutter and the dimming control or douser in the full open position. Project the spot to a wall or similar flat perpendicular area opposite the follow spot.

TURN THE CENTER FOCUSING SECTION of the bulb position control clockwise until a brown color with a hot spot is projected on the wall.

LOOSEN THE TWO THUMB SCREWS, one on either side of the center focusing section, just enough to permit manual movement of the complete assembly. The bulb adjustment control will now move around these two spring-loaded thumb screws.

575/006

BULB INSTALLATION AND OPERATION (continued)

MOVE THIS CONTROL SECTION around the two screws until the hot spot is centered in the brown circle of the reflector. After the hot spot is centered, tighten the two thumb screws to lock this adjustment section and turn the center focus control section counterclockwise to obtain the brightest light with the best light distrubution. Rotate the lens spot focus control knob, located on the front of the lens mechanism, to obtain the sharpest edge possible on the projected spot.

REPLACE THE REAR COVER PLATE over the bulb adjustment control mechanism.

Secure using the push-type fasteners.

THE FOLLOW SPOT may be turned off at the lamphouse or the power supply, whichever is most convenient to the operator. It is recommended that the circuit breaker on the rear of the power supply be placed in the “OFF” position, to function as a line switch, when the spot is off for any extended period of time.

WHEN TRANSPORTING, or if the bulb may be subjected to a hard shock when moving to another location, remove the assembled metal halide bulb from the lamphouse by reversing the installation procedures. If the control section of the bulb adjustment is not changed, the bulb should be able to be replaced without any necessity to repeat the aligning procedures.

THE METAL HALIDE BULB ignites better when cold. After extinguishing the bulb, allow at least one minute cooling before attempting re-ignition.

EXPECTED BULB LIFE is 750 hours, but because of manufacturing tolerances, some bulbs may lose color quality before this period.

BULB LIFE can be maximized by avoiding repeated ignitions. Allow the lamp to burn throughout the spotlight’s use cycle, dousing out with the masking shutter blades or fadeout mechanism as required.

RECORD the elapsed time meter reading when replacing a bulb.

575/007

OPERATION OF OPTICAL SYSTEM

THE IRIS CONTROL is the front lever which projects through the top of the optical system housing. When this lever is to the left, looking at the spotlamp from the rear, the largest aperture is provided. Smaller apertures are obtained as the lever is moved to the right.

THE SPOT SIZE CONTROL HANDLE is located on the right side of the optical system just above the base pan. A variation of spot sizes from full flood to a small spot can be obtained by moving the spot size control from one extreme to the other. Beam intensity is increased by this optical system when reducing from flood to spot and maximum intensity is reached when the spot size control is in the extreme forward position.

THE MAXIMUM FLOOD SPOT is obtained with the iris control lever to the left (away from operating side) for the large aperture and with the spot size control handle moved as far as possible toward the rear.

SMALLER SIZED SPOTS are porjected as the spot size control handle is moved forward.

Most of the spot sizes needed wiill be produced with the iris in its maximum open position.

FOR A “HEAD SPOT,” or any spot size smaller than can be obtained with the spot size control handle in its extreme forward position, shift the iris control lever to the right (toward operating side) for a smaller aperture. The iris control lever should always be returned to its extreme left position before the spot size control handle is again moved to obtain larger spots.

THE MASKING SHUTTER LEVER is the middle lever projecting through the top of the optical system housing. The masking shutter blades are operated by this lever to shape the projected spot to a rectangle, strip spot, or dousing.

THE DISENGAGED POSITION of the masking shutter lever is to the extreme right

(toward operating side) and varying degrees of masking to complete cutoff are obtained by moving the lever to the left (away from operating side).

CAUTION

ULTRAVIOLET RADIATION is emitted when the bulb is ignited. Wear protective clothing and goggles or glasses when adjusting the shutter blades or performing any service with the optical system housing removed.

575/008

OPERATION OF OPTICAL SYSTEM (continued)

THE ANGLE OF THE MASKING SHUTTER BLADES can be adjusted to compensate for the horizontal projection angle. Remove large lens shaft handle and knobs. Remove the optical system housing, and loosen (with an angle screwdriver) the screws holding each of the masking shutter blades just enough to allow adjustment. Ignite the bulb and adjust the angle of the bottom blade by tapping with a screwdriver so its projected edge lies parallel to the footlights; tighten the mounting screw in the bottom blade.

OPERATE THE MASKING SHUTTER LEVER to close the blades. Adjust the upper blade to close in line with the bottom blade. Tighten the screw to secure the upper blade.

THE FADEOUT MECHANISM AND DOUSER CONTROL is the rear lever projecting through the top of the optical system housing. This lever controls the intensity of light from complete fadeout when the lever is to the left, to full intensity when the lever is to the right.

THE LENS FOCUSING KNOB is located on the operating side of the optical system base pan (forward end) and is used to adjust the optical system for the length of throw. When making an adjustment rotate the spot focusing knob until the sharpest edge is obtained on the projected spot.

Moving the large lens to its center of travel and then adjusting for a sharp edge should give satisfactory results for the full movement of the lens system.

575/009

HANDLING THE SPOTLIGHT

GENERALLY THE BEST POSITION for the operator to stand is near the center of the spotlight, on the right hand side, although the angle of tilt and the size of porthole may alter the position for the most convenient operation.

EACH OPERATOR will, after a few minutes of operation, generally develop his own system and preferred position for operating the follow spot.

THE VERTICAL TILT LOCK LEVER located on the base assembly can be set to give the required amount of friction on the spotlight to suit the individual operator.

THE LENS CARRIAGE FRICTION BRAKE is located on the outrider of the large lens carriage and is preset at the factory for the most satisfactory operation. Individual requirements vary and the brake can be adjusted to suit the operator. Remove the color boomerang, reach through the color gel opening and loosen the locknut. Then adjust the screw on the friction brake until the desired tension is applied to the large lens carriage. Tighten the locknut and replace the color boomerang.

OPERATION OF COLOR BOOMERANG

THE COLOR BOOMERANG is equipped with six color filter discs containing the following colors in order from rear to front:: (1) Amber, (2) Flesh Pink, (3) Daylight Blue, (4) Light Sky

Blue, (5) Primary Blue, (6) Light Red. Keep the darkest or most dense colors to the front of the boomerang. A heat filter is mounted in a fixed position behind the boomerang to protect the gels.

THE SIX COLOR DISC LEVERS are mounted in the cover plate casting directly in front of the aperture selector lever. To insert a color disc in the light beam, move the proper color disc lever to the left as far as possible. To release a color disc, move the lever to the extreme right. Be sure that the lever is always fully returned to the limit of its movement.

TO REMOVE A COLOR DISC ASSEMBLY, remove the knobs from the aperture selector, masking shutter and fadeout levers. Remove the two end screws from the cover plate casting and lift off the complete boomerang assembly. The two split rivets holding the color disc assembly can now be removed and a new color disc assembly installed. Only the six above-mentioned color discs are supplied with the boomerang; additional colors are available from theatrical supply dealers.

575/010

MAINTENANCE

TO CLEAN THE SMALL LENS, remove the color boomerang assembly and using a good grade of alcohol and piece of lens tissue (facial tissue can be used as a substitute), gently wipe both sides of the lens until the surface is clean.

THE BACK SURFACE OF THE LARGE LENS can readily be cleaned by using the same access hole as above with the large lens carriage in the rear position.

TO CLEAN THE FRONT SURFACE of the large lens, slide the lens carriage to the full forward position. The front surface is now readily accessible through the front of the housing.

THE REFLECTOR should be cleaned periodically with a clean, soft lint-free cloth to remove any dust from the reflecting surface.

THE NEGATIVE LENS, mounted on the support for the fade-out mechanism, must be removed for cleaning. Use the same materials for cleaning this lens as recommended for both the small and large lens. The negative lens must be replaced with the curved surface facing towards the reflector and metal halide bulb.

THE INSIDE of the lamphouse and lens mechanism and the blowers should be cleaned periodically, depending on the dust conditions at each installation. The blower blades need cleaning to remove the dust build-up that accumulates over a period of time.

THE FOLLOW SPOT does not require any lubrication.
