Mitutoyo GML‑3701 WEC is a two‑axis machine controller with a 9‑digit LCD, 24 programmable buttons and multiple I/O connectors (3‑blade, 4‑pin, 5‑pin, 7‑pin). Common failure points for this class of controllers include power supply degradation (50/60 Hz input, 30 VA), display backlight or LCD module faults, button contact wear, and loss of signal on the I/O connectors. First‑check diagnostics: verify mains voltage and regulator output with a multimeter; inspect the LCD panel for flicker or dead pixels and test button continuity; review any error codes displayed or logged in the controller’s diagnostic menu.[oss-gpt-20b] |
