Hey folks, I'm curious to know if there are any U.S. codes that require motorized theatrical equipment to have an E-stop, or if it's "best practice" at best? I've found some guidelines that mention them, but nothing concrete or lawfully required yet looking at OSHA, ISO, etc. I'm specifically looking to put some weight behind the argument of needing to add an E-stop to a roll drop assembly (large projection screen) that doesn't have a way to stop travel once in motion. It's large, moves very quickly, and also can be activated from an iPad on the building's WiFi system--so in theory 5 floors away without eyes in the room.
My hope is to find some supporting documentation to back up the need for a new control system that can solve the E-stop and iPad control issues. And a motor/VFD replacement in future for the speed.
Thoughts?
