A system for programming automation by demonstration where a control program may be created or modified through the process of demonstrating desired behavior using graphical representations of physical, programming, and user interface elements. The filter clement de-emulsifies the emulsified contaminant oil from the oil-in-water emulsion into the contaminant oil and the oil-in-water emulsion, separates the de-emulsified contaminant oil from the oil-in-water emulsion, coalesces the separated contaminant oil and passes both the coalesced de-emulsified contaminant oil and the oil-in-water emulsion. At least one of the TDMAs includes first and second indicators. The auto transformers each have a first interconnection terminal and a second interconnection terminal.
