Mounting Sled to Shelf or Ceiling

User’s Manual

BX-AL133

When installing the motorized sled, make sure that you first mark screw locations using only the sled−without the lens and/or the lens bracket in place.

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.
