Four hours of diagnosis on a machine whose fault pattern has long been on record in the company's own service history.
The technician is standing at the machine; the fault pattern is an error code plus a particular behaviour on start-up. The service history holds hundreds of reports on the series, the manufacturer's manual runs to eighty pages, and nobody likes searching through either on a tablet in the field. So the measurements start again from scratch, even though the route to the cause is documented.
1fault reportAn inverter reports error code F41 and the machine shuts down with a fault.
380past cases for the seriesThat is how many service reports on this series are in the history.
3hits for the codeThree of them name the same code, and two also record the measurements.
4 hourson-site diagnosisWithout these reports, the cause is narrowed down again, one measuring point at a time.
45% faster fault diagnosis means the technician starts at the measuring point where two past cases ended, rather than from zero.
The 45% gain in diagnosis speed is this agent's headline figure. The 380 past cases, the three hits and the four hours on site sketch a typical service case and were not measured.
