The vertical limit switch allows the screen to drop to its desired level but sometimes, it can be over compensated. This discussion covers what to do in such a situation. The links below and dialog will walk you through the process.

[17:40] Customer: Hi there. I bought a Spectrum Electric Screen two weeks ago. Two days ago I was trying to adjust the limit switch and now the stop point does not work. The unit continues to attempt to retract the screen…including the counterweight, without stopping. I'm concerned that this could damage the motor or screen and would like warranty service to determine if damage has occurred and to repair the limit switches.
[17:41] Rick: I’m sorry to hear about this situation and would like to try a few things to hopefully save you a lot of time and effort.
[17:43] Rick: Here is the instruction file on operating your vertical limit switch : https://tawk.link/598aa11bdbb01a218b4db711/a/579b82be0995142b0d81b97f/876a5f22be0bc3d579b7e6152d1ee69ba0cf00b7/spectrum_2_Limit_switch_adjustment.pdf
[17:43] Rick: This provides the full instructions. In your case, the “up” position adjustment is the allen wrench port up in the slot (not the hole in the casing). Bring the screen to the full down position. Turn clockwise 3-5 full rotations. (each rotation pays out an extra 1” of screen) If it is too much, turn counter clockwise and adjust accordingly.
[17:44] Customer: Sounds good. If it does not work, what next?
[17:44] Rick: The instructions will walk you through it. If it does not work, here is the link for the warranty form if needed.

[17:44] Customer: I'll have a look; thanks for this. Is there a rule of thumb for determining if the screen has been damaged?
[17:44] Customer: Also, can you tell me what the warranty period on this screen is?
[17:45] Rick: The warranty is 2 years on purchase date.
[17:46] Customer: Ok. Thanks for your help.
[17:46] Rick: you're welcome, also keep track of your turns in case you need to back track.
[17:46] Customer: will do
[17:52] Rick: Thank you for choosing Elite Screens.
*Note: No RMA was ever filed indicating that the vertical limit instructions were successful.
