ABSTRACT:
An automated trash compaction system having an hydraulic cylinder displacing a ram to compact trash in a mobile trash container and having an electronic control unit controlling the displacement of the ram. The electronic control unit generates a ram forward signal in response to a start signal, generates a part-full signal in response to electrical current being supplied to an electric motor driving a fluid pump exceeding a part-full value, and generates a full signal in response to the current being supplied to the electric motor exceeding a full value. After a predetermined full stroke time or upon the generation of the full signal, the electronic control unit terminates the ram forward signal and generates a ram return signal returning the ram to a retracted position. The ram return signal is terminated when the current to the electric motor exceeds a predetermined value. The electronic control also has calibration subroutines for automatically generating the predetermined full stoke time, the part-full value and the full value.
