Here is a great example of Elite’s service team giving detailed instructions on how to adjust a projection screen’s drop or “vertical limit adjustment”.

4:00:00 PM Johnny - Thank you for contacting Elite Screens Technical Support. This is Johnny, how may I help you?
11:06:36 AM Customer - Hello. I have an ETB120HW2-E8 screen (link) and installed it. I am trying to figure out how to program the 8-inch drop to come down only 2 inches whenever I switch on the screen.
11:06:54 AM Customer - now it drops 8 inches; how do I adjust the vertical setting to drop less?
11:07:14 AM Johnny - This is a common question and you were right to contact us first. Adjusting the Vertical Limit Switch can damage your mechanism if done improperly. However, I can walk you through it step by step.
11:07:41 AM Johnny - Please see link to the instructions on how to set the limit switches on your screen:

11:07:55 AM Johnny - Step 1: Before starting the procedure, you will have to lower your screen material until it stops on its own.
11:08:01 AM Johnny - Step 2: then insert the (5/32”) Allen wrench into the bottom key hole, not the top. The top hole limits rise; the bottom hole controls drop. Keep in mind that each full rotation will either add or remove one-inch of drop. In this case, make 6-full rotations clockwise to remove 6-inches of drop.
11:08:08 AM Johnny - Step 3: After turning the Allen wrench, you will not see any adjustment being made to the screen because the mechanism itself is being reset. After making your adjustment, raise the material up almost the full way, then press stop, and bring the screen material back down again. Then you will see the material is now stopping at a lower height setting.
11:08:15 AM Johnny - Step 4: Repeat the process turning clockwise to remove drop and counter-clockwise to add drop. Keep in mind that running the motor too often will trigger a kill switch to keep the mechanism from overheating. If the motor quits, give it some time to cool down before resuming.
11:13:31 AM Customer - Okay, I am looking right up into the slot that the screen drops down and I see the “bottom” port nearest to the wall on the left hand side. Correct?
11:13:34 AM Johnny - Yes, correct. The left hand side of the screen, port nearest to the wall.
11:14:16 AM Johnny - the best way to locate it is to follow the screens roller all the way where the material ends on the left hand side
11:14:21 AM Johnny - on the power cord side
11:14:28 AM Johnny - and there may be a “do not remove” sticker
11:14:32 AM Johnny - that you can go ahead and remove.
11:14:59 AM Customer - Got it. I think I have it from here. Thanks for the help.
11:15:35 AM Johnny - Fantastic. Thank you for reaching out. If you need anything else, please let me know but in the meantime, thank you for choosing Elite Screens.
