Clarity WN=5230-S manual Adjusting the Image

WN-5230-S VideoWall User’s Guide

For an image that is way out of alignment and that needs major adjustment, start with everything in a “normal” position:

•If the screen is Ultra-Thin Mullion, remove the screen and check that all the pointed alignment bolts are at the same distance. Put the shipping shim behind each bolt and tighten the bolt to it. (Later, when building a wall, make sure that the main chassis of the cubes are aligned. It is a mistake to move the screens in and out a great distance with the pointed alignment bolts to compensate for main chassis that are not even with each other. Moving these bolts a lot will change the image size, because the lens-to-screen distance changes.)

•Each corner of the optical engine mount should start at the same distance out. Factory default is 3 cm, but any distance near this amount will do a good job. Make a block of wood that is 3 cm thick and use it as a gauge at the four corners of the metal engine mount. Then adjust S1, 2, 3, and 4 to make the engine mount just touch the block.

•Adjust the lens screws, LS1 and LS2, so they are part way in. As these screws turn out, eventually they reach a point where the spring no longer pushes the lens toward the screw. Have the lens in a middle position, so that the spring is pressed some, but not as much as half way.

Adjusting the Image

There are four nuts on the engine mounting plate, S1, S2, S3, and S4. Adjust these in pairs and turn them equal amounts.
