The CamacXTC 1‑288‑0028 is a controller‑monitor workstation used in Cincinnati Milacron process control systems, featuring a CRT display and integrated I/O for field devices. Common failures on this class of units include power supply degradation (especially the main transformer and rectifier), LCD/CRT backlight or phosphor burn‑in, and failure of the onboard microcontroller or communication interface due to over‑temperature or voltage spikes. Initial diagnostics should verify that the unit receives correct input voltage and current from the mains supply, inspect the CRT for visible damage or loose connections, and check all I/O pins for continuity and proper signal levels; if available, review any error logs or diagnostic LEDs for clues to a controller fault.[oss-gpt-20b]
