[Cause]
A 3-dimensional wide-area sensor alarm occurred. The projector is in use by another process. This alarm occurs when multiple processes try to control the projector simultaneously, such as acquiring a 3-dimensional map from the 3-dimensional wide-area sensor teaching screen while a 3-dimensional map acquisition instruction is running in a program.
[Countermeasure]
Configure operation so that a 3-dimensional map is not captured from the teaching screen while the production line is running.
