An instrument fault indicates a loss of monitoring on one or more points. When an instrument fault occurs, the
following actions take place within the Vertex M System:
The LED indicator flashes yellow on the analyzer with the fault. See
• A yellow fault indicator appears on the main screen
• The fault is entered into the event list and event history
• Instrument Fault relays associated with this analyzer will activate
