R 408.14522 Machine controls.

Rule 4522. (1) An operating control on a machine, except a stop button, shall be so located or guarded to prevent accidental contact. (2) A machine requiring more than 1 operator shall have controls for each operator which shall be activated concurrently before the machine will operate as prescribed in R 408.14541(1). (3) A machine shall be provided at each work station with a non-concealed emergency stop device distinguished by its size or color. (4) A machine shall be equipped so that upon power failure it will not automatically restart upon restoration of the power. (5) An automatic die casting machine shall be equipped with a time delay device or circuit that will prevent the machine from recycling if more than 2 seconds delay occurs between the automatic demand for recycle and its commencement. It shall be necessary for the operator to reset the controls before the machine will restart. Other equivalent means may be used that will prevent recycling until the machine is cleared if the intent of this subrule is met. (6) A safety interlock, exposed to contact, shall be guarded against accidental actuation.
