  • Visible harness damage: Stop. Do not operate machine with damaged wiring. Hand off to technician.
  • If the flickering pattern suggests an intermittent connection issue, testing the power quality at the controller output requires a qualified technician.
  • If visible harness damage is noted during movement checks, service must be escalated to a qualified technician immediately.
