Elgo 74.600.230 Controller

Elgo 74.600.230 is a 230‑VAC industrial controller featuring a 12‑digit LED display and manual operation mode, commonly used for temperature or process control in factory automation. Typical failure points for this class of units include power supply board faults (overvoltage, capacitor degradation), I/O module wear, and firmware corruption that can cause the display to freeze or error codes to appear. First‑check diagnostics: verify mains voltage and continuity on the input terminals; inspect the main PCB for burnt components or loose solder joints; review any displayed error codes against the Elgo service manual to pinpoint the fault source.[oss-gpt-20b]
