Access protection

The M4000 multiple light beam safety device safeguards access to the crane loading station. WL18-3 small photoelectric sensors differentiate between person and paper roll and mute the system accordingly. The Flexi Soft safety controller connects the reset pushbutton, the ES21 emergency stop pushbutton and all other safety components.
