Reparation of industrial electronics begins with precise diagnostics. It is advisable to avoid searching for the cause of failure yourself and immediately replacing suspected faulty units with new ones, which can result in a lengthy and costly repair, as the cause of the problem may not necessarily be the unit itself. An effective component-level repair quickly restores the unit to function and extends its life. The diagnostic process first identifies the potential cause of failure and assesses the performance of individual components, eliminating weak links in the system and replacing faulty parts.

In cases where it is not possible to fully commission the unit and check all signals on the board during repair, conditions close to actual production conditions are created in the laboratory.

Test benches in the repair laboratories are used to test the efficiency of the units. The presence of these stations optimises the process at all stages. Technologically advanced equipment allows the unit to be tested in various modes of operation 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.
