Systems and methods for operating an overhead door opener and a lifter are disclosed. The lifter is positioned above the overhead door when the overhead door is in a retracted position and raises and lowers objects along a path that, without care, will intersect with the overhead door. A controller monitors the position of the overhead door and the lifter and moves the overhead door if the lifter is out of the way, and if the lifter is not out of the way the command is not executed to prevent interference between the lifter and the overhead door.
