Threshold alarms fire when a reading crosses a line. By then the failure mode is usually advanced, the intervention window narrow, and the diagnosis manual.
This system works from a different starting point. It learns what healthy operation looks like during commissioning. When behaviour departs from that baseline, the system classifies the departure: is it routine variation, something worth monitoring, or something requiring action?
The output is a three-state decision: ROUTINE, MONITOR, or ESCALATE. Not an anomaly score. A structured assessment of what is changing, how fast, and what kind of intervention it maps to.
A separate fault signature layer identifies what kind of departure is occurring, not from pattern matching against known failures, but from the pattern of physical signals in early departure. The system tells the operator not just that something is wrong, but what is wrong.
