BX-AL133 Anamorphic Lens User's Manual User's Manual BX-AL133 Safety 1. Read and understand instructions and heed warnings before beginning installation. 2. Mount rail securely. The lens is heavy, and requires a secure and stable surface. Fasteners in sheetrock alone are not safe. Reciprocal lens motion can and will work them loose. Use a board, plate, or projector mount fixed to ceiling joists or studs. 3. Anticipate unexpected lens motion. A malfunction can cause the lens to move unexpectedly. Disconnect the power when installing, working on or repositioning the lens. While on a ladder, do not stand in the direct path of the lens in case of unexpected or accidental movement. 4. Do not install the lens in a wet or moist environment, or where the mechanism will be exposed to extreme or external weather conditions. The lens is for indoor use only. 5. Never pour any liquid or push any object into the enclosure. 6. Do not install in direct path of heater vents or projector exhaust ports. Do not block any of the vents or holes in the enclosure. 7. The power adaptor is intended for 100- 220 volt, 50-60 cycle AC power only. 8. Do not subject power cord to conditions which will wear through or cut the insulation. Avoid excessive tension or chafing of the cord. 9. Do not service the motor drive or electronics. There are no user serviceable parts. Contact your dealer or send to a factory approved facility. Opening the case will void the warranty. 10. Exercise extreme caution when working on a ladder. Do not work directly above another person, particularly a child. Plan all work carefully. Accidentally dropping a drill, hammer, or the lens assembly can cause serious bodily injury. 11. Pushing or forcing the sled by hand may damage the circuit board. Should it be necessary to move the sled by hand, make sure it is done slowly and lightly. 12. The Optoma motorized sled will ramp up and down at the beginning and end of the traversal to minimize swaying forces at the mount. As the motor accelerates and brakes, there is a minimal change in the sound. This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

To the ceiling or projector mount above the projector 2. To a shelf or table below the projector When attaching the motor assembly to the ceiling, use a board, plate or lens-enabled projector mount that is attached to ceiling joists or studs. Sheetrock embedded fasteners can and will become loose with repeated lens movement, causing the mechanism to fall, resulting in possible severe injury. Planning for Projector Exhaust Some projectors have hot air exhaust ports that discharge from the front. Avoid situations where the lens or housing will block or obstruct the warm air flow out of the projector, as damage to the bulb and/or the lens may result. You can mount the sled either to the left or right of the lens. During setup, you can easily configure the "lens-in" position to be on the motor housing or pulley housing side of the sled. (See Setup). Changing Orientation of Logo Plate (Optional) The lens sled is configured for ceiling mounted operation as shipped. As such, the logo reads right side up with the mounting bar on top. If you are using the sled in a table or shelf mounted configuration, you will want to turn the logo around so that it is right side up with the mounting bar below the projector. To reverse the logo, remove the 4 screws securing the motor housing cover. Lightly slide the sheet metal cover and lift it off. Once removed, you can easily access the logo plate. Remove the two small screws securing the logo plate, turn the plate around, and re-install the screws. Install the motor cover housing back on the sled with the original screws. The logo backlight may be turned off using the remote control. An alternative to reversing the logo plate is to simply turn off the back light to make the logo less conspicuous.

Do not rely on fasteners embedded in sheetrock alone. Reciprocal lens movement can and will work them loose and cause the mechanism to fall. Mount the sled on a plate, board, or lens-enabled projector mount affixed to ceiling joists for safety. Once the sled is secure, attach the bracket to the lens adaptor plate. Then, only after properly aligning and positioning the bracket, power up the sled and check the alignment again. Finally, attach and adjust the lens to its correct angle and vertical position. Follow this procedure: 1. Line up the center line of lens There are score marks on the back of the mounting bar that correspond to the center of the BX-AL133 expansion lens. Before starting, the projector must be correctly focused with the zoom and iris set in their viewing positions. This will assure that the front of the lens is positioned correctly. Hold the motorized sled up to the projector and determine if the LENS IN position will be on the motor housing (logo side) or the pulley housing (smaller box) side. This will determine the score mark you will use (see below). Measure 2-1/8 inches from the front of the projector lens, and lightly draw a line parallel to the front of the lens. Mark the center line of the projector lens along this parallel line. Line up the back of the mounting bar to the parallel line just marked. Align the center of the projector lens mark with the correct score line on the mounting bar, and mark the six drill hole locations using the mounting bar itself as a template. Drill out the holes for the fasteners.

Securing the mounting plate Because the mechanism and lens are heavy, make sure the mounting fasteners and surface are extremely secure. Remember that the sled motor will be starting and stopping a heavy weight thousands of times through normal use. Ceiling mounted lenses require a secure surface. Sheetrock anchors alone are insufficient. Secure the mounting bar to a plate, painted board, or lens-enabled projector mount that is securely affixed to the studs or ceiling joists. Use of a commercial mounting system enabled for anamorphic lenses is highly recommended. Use all six screw holes, and tighten fasteners securely. Vibration from the motor and reciprocal lens movement will loosen any fasteners that are not absolutely tight and secure. Do not attach the lens or power up the sled yet! Adjustment and alignment are much easier at this point without the lens. 3. Attaching the lens bracket to the adaptor plate Remove the bracket mounting screws from the inside holes in the adaptor plate and use them to attach the lens bracket supplied with the Optoma BX-AL133 anamorphic lens system. If the lens is attached to the bracket, make sure to remove the lens prior to attaching to the lens adaptor plate.

Power up the sled and set LENS IN position Slide the lens into the middle of the sled before powering up. Plug the power adaptor into an AC outlet, then into the back of the unit as illustrated. Using the remote, press the "lens in" button. The lens sled will slowly position itself into the factory default LENS IN position. The edge of the adaptor plate will land about a half-inch from the motor housing side of the sled. If the bracket is in front of the projector lens, proceed to the next step (Verify centering). If the bracket is not in front of the projector lens, you will need to change the setting. Simply press the LENS OUT button on the remote, and wait for the bracket to move in front of the projector lens. Press and hold the LENS OUT button again for 5 seconds. The sled will confirm the new setting by moving the bracket away from the projector lens to the new LENS OUT location. The edge of the adaptor plate will land about a half-inch from the motor housing side of the sled. You have now reprogrammed the sled. This setting will be preserved in the unit even if it is unplugged or undergoes a power failure. To change back, just repeat the above procedure.

If needed, make small adjustments (+ or ­ a quarterinch) to the lens bracket after disconnecting the power, by loosening the screws and sliding the bracket to the left or right as needed to achieve centering. 0.5" Gap Reconnect the power and check the centering. The optical sensors will stop the edge of the lens adaptor plate approximately a halfinch from the housing on either side of the sled. You can use this gap on the motor or the pulley side for fine-tuning adjustments.

Attaching the lens to the bracket Attach the Optoma BX-AL133 anamorphic lens to the bracket using the plastic knobs supplied with the lens. Adjust the anamorphic lens vertically for correct alignment. When the image is correct, tighten the knobs against the bracket. Using the remote, test run LENS IN and LENS OUT commands. Tighten Knobs 4. Configuring the lens speed The lens has two operating speed modes ­ FAST and SLOW. Slow is the default from the factory. The slow mode reduces the inertia exerted by the lens on the mounting system by accelerating and decelerating very slowly, and by limiting the top speed of the lens as it traverses the sled. If the sled is on a very rigid mount that is not subject to any sway, you can speed up the traversal speed by setting the lens speed to FAST. If you notice any swaying in the mounting, reset the speed to SLOW. Some users set the speed to SLOW when used in conjunction with screen masking s ...
