Before using a code meaning

  • A matching number is not enough when a different brand or controller uses the same characters.
  • Read the public source and check that it covers the machine label.
  • Follow only owner-safe actions supported by the exact manual.
  • Escalate repeated alarms, uncertain operating status and hazardous-system work.

Read the source policy and safety framework for the site-wide rules.
