Updated 2026-10-22 · LogrobotLM reference

Description

The SVOFF1 status is still ON when the SVOFF signal is asserted.

Remedy

Repair the SVOFF1 circuit.

Field diagnosis

Chain alarm on channel 2 of the fence signal.

What to check

  • Same diagnosis as SRVO-266 (EAS circuit on both channels, timing between channels), then the emergency stop board if the wiring is sound (backup before replacement).
  • Release: emergency stop pressed/released, RES_1CH, RESET.
  • Note: The 266/267 pair indicates which channel is lagging; both together rather point to the board.
