Event Codes And Recommendations - ABB LWT300 Series User Manual

Event codes and recommendations

Below is a list of the event codes that your LWT instrument might display should a problem arise, and
recommended action for each event. The first letter of the code refers to NAMUR codes:
• F: Failures
• S: Function check
• C: Out of specifications
• M: Maintenance request
