1. A monitoring system for use in a waterless container cleaner having a container cleaning queue for holding a plurality of containers to be cleaned, a pressure blower, a pressurized air line having a pressurized air line filter, a vacuum blower, a vacuum air line having a vacuum air line filter, a compressed air line having a compressed air line filter, and a compressed air line regulator having a reservoir for collecting condensation within said compressed air line, said monitoring system comprising:

  • a digital controlled having a plurality of inputs and at least one output;

    a visual display unit in electrical connection with said at least one output of said controller, said visual display unit displaying a plurality of predetermined messages in response to receipt of various signals from said controller;

    a first differential pressure sensing means, having a first and second pressure input, for sensing the pressure differential across said compressed air line filter, said first pressure input being in functional connection with said compressed air line at a location downstream from said compressed air line filter, said second pressure input being in functional connection with said compressed air line at a location upstream from said compressed air line filter, said first differential pressure sensing means having a first electrical output in connection with a first one of said inputs of said controller, said first differential pressure sensing means supplying a first input signal to said controller when a predetermined pressure differential level is sensed across said compressed air line filter;

    a second differential pressure sensing means, having a third and fourth pressure input, for sensing the pressure differential across said pressurized air line filter, said third pressure input being in functional connection with said pressurized air line at a location downstream from said pressurized air line filter, said fourth pressure input being in functional connection with said pressurized air line at a location upstream from said pressurized air line filter, said second differential pressure sensing means having a second electrical output in connection with a second one of said inputs of said controller, said second differential pressure sensing means supplying a second input signal to said controller when a predetermined pressure differential level is sensed across said pressurized air line filter;

    a third differential pressure sensing means, having a fifth and sixth pressure input, for sensing the pressure differential across said vacuum air line filter, said fifth pressure input being in functional connection with said vacuum air line at a location downstream from said vacuum air line filter, said sixth pressure input being in functional connection with said vacuum air line at a location upstream from said vacuum air line filter, said third differential pressure sensing means having a third electrical output in connection with a third one of said inputs of said controller, said third differential pressure sensing means supplying a third input signal to said controller when a predetermined pressure differential level is sensed across said vacuum air line filter.
