Applicable scene
Suitable for remote mines, high after-sales on-site service costs, repeated alarms, or sites where remote engineers need to make the first diagnosis.
Remote service requests fail when information arrives in pieces: one controller photo today, a video tomorrow, and filter history later. Engineers need the full picture to define the fault and reduce waiting downtime.
A fault report does not need polished wording; it needs the key facts in one submission: which unit, what alarm, what load condition, how long it has run, what maintenance was done recently, and what the site can handle first. These facts determine whether engineers can guide remotely, prepare spare parts, or schedule a site visit.
Equipment and controller information
- Equipment nameplate, engine nameplate, generator nameplate and controller model photos.
- Current alarm code, historical alarm list, controller home page data and shutdown page photos.
- Appearance photos of control cabinets, terminal blocks, circuit breakers, ATS or parallel cabinets.
Operation and maintenance records
- Current operating hours, daily operating hours, load rate and main electrical equipment when the fault occurs.
- Last maintenance time, maintenance items, which filters, oil, belts, batteries or sensors were replaced.
- Whether new equipment was added, the startup sequence was changed, the load was adjusted, or power outage switching occurred before the fault.
Visible site symptoms
- Take videos before and after the fault, including controller data, generator set sound, exhaust smoke, fuel system, radiator, and load status.
- Record oil pressure, water temperature, voltage, frequency, battery voltage, fuel level and ambient temperature.
- Indicate whether the failure affects drainage, crushing, ventilation, communications, camps, or other critical loads.
