Abstract
A control system is used for remotely operating an apparatus powered by a main power source. The control system includes an auxiliary power source to provide power to the apparatus upon a loss of power to the main power source, and first and second light-emitting sources positioned remote of the apparatus. A first photoelectric sensor is positioned proximate the apparatus and interconnected with the apparatus and the auxiliary power source, wherein upon a loss of power to the main power source, the first photoelectric sensor receives light from the first light-emitting source and the first photoelectric sensor enables power to flow from the auxiliary power source to the apparatus. At least one second photoelectric sensor is positioned proximate the apparatus and interconnected with a component of the apparatus and the auxiliary power source, wherein upon a loss of power to the main power source, the second photoelectric sensor receives light from the second light-emitting source and enables power to flow from the auxiliary power source to the respective component to activate movement of the component.
