Every morning, where to start
It starts from the alarms waiting to be taken and from the machine's page. There the current values sit beside their limits, and the «Variabili» tab shows at once which measure is out of limits. From a variable, Analisi opens on the last hours with the limit bands.
A health index from 0 to 100
The flows' «Indice di salute» recipe combines a few of the machine's measures, in the video the oil temperature, the vibration and the delivery pressure, into a number from 0 to 100. The result is saved like any other measure: it can be watched over time and, with «Avvisami quando…», raise a notice below a chosen level.
When it drifts from normal
Before any threshold trips, one predictor flags when a line behaves differently from usual, and another estimates the probability that an episode starts within a horizon. They are estimates, not the date of a failure: what to do stays with whoever knows the machine.
Thresholds tried on the past
On the oil temperature the threshold is judged on a smoothed value and trips only if it stays above for at least ten minutes. Before it is switched on, «Prova sul passato» shows what it would have done over the last 30 days beside the starting rule: in the video the needless alarms drop and the real episodes stay.
Who to tell, with a first diagnosis
Every alarm says who to tell and when: when it goes into alarm, when it returns inside its limits, and again if nobody takes it.
With assisted diagnosis the alarm arrives with a few hypotheses about its causes, each with its sources: the machine's variables around the moment, its documents and its manuals. They are hypotheses written by AI and never suggest an action on the plant; since they use the platform's model, an administrator switches them on.
From the alarm to the repair, and back
The team takes the alarm, classifies it as maintenance, notes what was done and suspends it for the length of the work. When the temperature comes back, the register keeps every step with who and when, and the health index climbs again.
Reports and alarm health
A notebook can send one PDF per compressor, on a schedule or when a machine goes into alarm. The «Salute degli allarmi» page counts how many alarms sound, which disturb most and how many were classified as false, with ISA-18.2 references, per project and per machine.
Athena on watch
A check is asked of Athena in one sentence, for example: tell me if compressor C-102's oil runs hotter than last week. Athena saves it among the «Controlli» and checks it by itself, saying when it noticed something.
What it is not
Predictive maintenance here is not a ready-made product: it is how alarms, the health index, predictors, reports and Athena work on the same machine, each with its own module. The plant and the data in the video are for demonstration, and Muvia states no accuracy.
