ABSTRACT:
A control assembly for use in a feed delivery assembly comprises a housing having an inlet, an outlet, and a chamber between said inlet and outlet. The chamber is opened in a plane parallel, but radially offset from, an axis of the inlet and outlet. A tube member is removably receivable in the chamber. The removable tube member includes a tube having a length sufficient to span a distance between the inlet and outlet tubes. At least one infrared emitter and at least one infrared receiver are mounted on the tube member tube and are positioned to be opposed to each other such that the receiver will receive and detect light from the emitter. The emitter and receiver are operatively connected to a controller. The controller emits a signal when it is determined that the light from the emitter to the receiver is interrupted.
