Berger‑Lahr MI‑2498.10 is a compact industrial controller used in motion‑control and automation systems, typically interfacing with stepper drives or servo motors. Common failure points for this class of units include power‑supply degradation (especially the 62 V rail), damaged I/O connectors, and internal PCB component burn‑outs such as electrolytic capacitors or diodes. Initial troubleshooting should verify that the input voltage is within spec, inspect all solder joints and connector pins for corrosion or breakage, and review any diagnostic error codes displayed on the controller’s status LEDs or panel. If the unit still fails to boot after these checks, proceed with a detailed board inspection focusing on the power‑regulation section and I/O buffer chips.[oss-gpt-20b]
