Warning

Updated 2026-09-17 · LogrobotLM reference

What it means

A protective stop (guard circuit) is active — a gate, light curtain or equivalent opened the safeguard chain. The robot cannot run until the guard is closed and reset.

What to check

  • Identify which guard input opened (cell door, curtain, mat).
  • Check door switches/interlocks wiring and alignment.
  • Chattering guard signals (vibration, loose connector) cause intermittent stops.
