A magnetic separator is specified on field strength, but it is judged on whether that field is still there after a year of continuous duty. Most early-life failures are thermal or electrical — a coil that runs hotter than designed, a connection that loosens, a power module that drifts under load — and none of these show up in a short functional check.
So every unit runs a 24-hour burn-in before it ships. The machine is energised at working field strength and left running while we log coil temperature, current draw and the stability of the control system over a full thermal cycle.
The test is deliberately long enough to reach steady state. Components that would drift or fail in the first weeks of service tend to declare themselves inside that window, in a workshop where the fix is a part and an hour rather than a site visit and a production stoppage.
It also gives us a baseline. The logged values travel with the machine, so if a customer reports a change in performance months later, we can compare against how the unit actually ran on our floor instead of guessing.
