Preventive and corrective maintenance service

The instrumentation installed in the field is naturally subject to the wear of its mechanical parts, pollutants and the drift of the quality of the sensitive elements. Constant maintenance allows to preserve their state of efficiency at the same performances guaranteed at the installation, it helps to prevent breakdowns and also reduces the costs related to a possible recovery of operation.

Therefore, besides installation, LSI LASTEM offers a preventive maintenance service with scheduled interventions, aimed both at checking the status of the hardware, and at updating the firmware and software, thus ensuring the quality and continuity of the recorded data.

Alternatively, the customer may choose corrective interventions on call, for the resolution of any sporadic problems, which will be managed by our Customer Service, according to its scheduling of interventions.

Moreover, within the scheduled preventive maintenance contract it is possible to foresee corrective actions. Defining in advance intervention times and costs guarantees a faster procedure for support ticket opening.

Preventive and corrective maintenance service

Highlights

  • verification of the state of conservation, cleanliness and stability of the mechanical parts. Over time, the mechanical structure can lose its stability, dirt can affect the quality of the data collected and more generally mechanical problems may arise. The technician assesses the structure and intervenes as much as possible, if an ad hoc restoration is required, he reports it. The technician provides thorough cleaning of the sensors and parts exposed to bad weather where dust and smog accumulate.
  • Check the power system. Solar panels and batteries can lose their efficiency over time without giving signs of malfunction, therefore specific measurements are required. Even medium power transformers can lose their safety requirements over time. The LSI Lastem technician checks these elements, indicating if replacement is necessary.
  • Check sensor operation and measurement quality. The LSI Lastem technician carries out a series of comparison measurements with certified instrumentation placed next to the present one. At the end of the test, if the data of the instrument to be tested has a deviation greater than the uncertainty of the verification process, the technician will report that the sensor is suspect or faulty. At the end of the operation, a test / calibration report is issued, complete with the results of the tests and indications of any suggested corrective actions.
  • Replacement of parts subject to normal wear. In some sensors, especially meteorological ones, some elements are subject to natural wear over time. Hygro-sensitive elements, filters, salts-gels, pads etc. must be checked and eventually replaced or reconditioned.
  • Verification and testing of local and remote communication, software update. Modems and LAN converters must be checked to ensure that data arrives correctly and consistently to the receiving system. The technician tries to update the communication and data management software in order to ensure the stability of the functionality and the more general safety of the system.
  • Creation of reports. At the end of the intervention, a report is issued with a description of all the operations performed and their outcome.
