Repairing industrial electronics starts with a thorough diagnosis. Avoiding searching for the cause of failure yourself and immediately replacing suspect units with new ones is recommended, as this approach can lead to a lengthy and costly repair, as the problem may not lie in the unit itself. An effective component-level repair quickly restores the unit to full function and extends its life. During diagnostics, the potential cause of failure is identified and the performance of individual components is assessed, eliminating weak links in the system and replacing faulty parts.
In situations where it is not possible to fully commission the unit and check all signals on the board during repair, the laboratory reproduces conditions close to actual production conditions.
To test the efficiency of the units, test benches are used in the repair laboratories. The presence of these test benches optimises the process at all stages. High-tech equipment allows the unit to be tested in various operating modes both during and after repair. A variety of tests are carried out to confirm the correct operation of the unit and its compliance with the required parameters.
