Chance,

You may just need to reset the stopping point again.  We had a screen do the same and we reset it and it has been working fine.  We also use Crestron to control our screens coming down so that may have something to do with ours.

What brand/model of motorized screens are you adjusting? I've had issues with this before and it mostly just took time adjusting the limit switches. 

Hello Chance:  On rare occasion the limit switch in the roller motor control box breaks and needs to be replaced.  Open the box at the motor and see if it has just skipped out and can be reset. If not, then order a replacement part and have an AV provider do the install. If you happen to have someone in-house that can change it out and adjust it, you can save a few hundred dollars.  Good luck on the repair.    Eric Johnson   University and Student Centers, University of Texas Arlington

Hi Chance,

There are different systems out there for travel limit.  I would bet that even though the limit adjusted you might have over used the limit screw range.  Typically you spec a screen with an amount of leader at the top so that the focal point drops in where you want it.  Sure you can alter that but you would still be leaving screen on the roller.  By leaving a good amount of material on the roller you might have a malfunction in the limit system.  I have seen tensioned screens installed to trim at different heights to make ratios although they never work well as you need to have the curve on the screen mature for it to work right.  

Without seeing your set up and heights it's hard to know exactly what you are dealing with.  I have seen far better success with masking kits instead of using the screen motor to limit travel.  For instance, if you have a tall space and want to cut the height, instead shorting how much unrolls, maybe it is wold be better to set up a short pipe and drape kit from the bottom on the floor.  You will still get a finished look at the top this way.

Again not know the space so sorry if this won't help, if in theater type setting with any flyable curtains you can bring in a boarder to mask from the top so the screen is still being used within its normal range.

That last thing I will mention is that there are some neat motors out there that have more sophisticated limiting systems.  Da Lite has a system now that is mated to the material and calibrated based on motor turns so that it is measuring the amount of screen you have unrolled.  You create set point and then recall them instead of relying on the physical limit screw that fall out of adjustment.

Sorry for the delay in getting back with you all. Thank you for the advice. over the last week, we had a tech here doing the programming for the creatron system. The entire system and it looks and works so much better. We will see how the new programming helps or hurts the screen adjustment. 

The screens are Draper screens. They are screens that are at least 15 years old. They are not self tensioning. as far as the space goes, it’s a banquet space. The screens are at the House left and right of the room. We have done the route of having ground support screens and it just gets really inconvenient with the different uses of the room and having to move the screens all the time. 

I dont really like having to ask about the screens because I know the better answer is to just replace the dang things but our budget just doesnt support that right now. 

I had our techs adjust the screens again but I’ll next time I’ll go look at the adjustment setup to see if they are broken. 

Thank you for your input. I’ll go look at the adjustment setup to see if that is the problem.
