Figures 1113 show the fault diagnosis of the chlorine sensors 0794, 0795 and 0801, respectively. Tables 3–5 show the diagnosis anticipation of our approach regarding the events reported by the WU experts. Each row represents a sensor fault detection produced by our approach. The columns start detection and end detection are the date interval during which our approach detects a sensor fault, the column event reported is the date when the WU expert detected the fault and anticipation is the number of days in advance provided by our approach regarding the event reported.
