In a cheese plant the metal detector is usually a critical control point: the last place a lost knife bolt, a wire fragment or a chip off a guillotine is caught before it ships. Operators run test pieces through it every shift. Maintenance's monthly check is the other half — that the reject device actually removes what the head finds, the bin is locked, the line stops on a fault, and nobody has quietly changed the validated settings.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.
In a cheese plant the metal detector is usually a critical control point: the last place a lost knife bolt, a wire fragment or a chip off a guillotine is caught before it ships. Operators run test pieces through it every shift. Maintenance's monthly check is the other half — that the reject device actually removes what the head finds, the bin is locked, the line stops on a fault, and nobody has quietly changed the validated settings.
The head still alarms on the test piece, so the check passes, but the reject arm is slow and the product carries on down the line. Or sensitivity was turned down to stop false rejects on wet product and never recorded. Either way it surfaces as a customer complaint, with every block since the last good check in question.
Monthly for the mechanical and settings check, alongside operators' test-piece checks at start-up, changeover and through the shift as the HACCP plan sets. A missed reject puts product since the last good check on hold. Settings belong to QA; this check records them, it does not set them.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
