7.4 Instrument Faults
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:
l
The LED indicator flashes yellow on the analyzer with the fault. See "Manual Analyzer Override" on page154 for more information.
l
A yellow fault indicator appears on the main screen
l
The event list and event history are updated
l
Maintenance Fault relays associated with this analyzer will activate
