14.1 Monitoring system health
The System Health screen displays diagnostic information. Operators can quickly be alerted to
any system maintenance or repairs that require attention, as well as troubleshoot startup
issues.
Figure 14-1 System Health screen
The System Health screen shows the high level summary of the functional status of each device.
Click on either of the CPU LED's to show the status for that device in greater detail. Click on the
LED for an individual circuit breaker to view a greater level of detail of the status of the
Messenger associated with that circuit breaker.
System health for hardware, firmware, communication and control power are monitored and
their condition will propagate to the Health Button and will alert the user of the following
conditions:
• Loss of redundancy: (Yellow) Lost redundancy but no loss in performance. In this case,
the respective device and ultimately the System Health screen will annunciate yellow.
• Hardware Error: (Red) Loss of performance. Will annunciate on the failure of a critical
subsystem or on the loss of a redundant subsystem and should be addressed
immediately. For example if a Messenger is not commissioned or there is a hardware
issue, the gear may not perform as expected. Will supersede yellow alerts.
The specific status information is outlined in Figure 14-2 and Figure 14-3. When a problem
occurs within the system (red indication), a review of the Sequence of Events log is useful in
determining the time of the failure and what may have led up to it. If the information still does
not indicate the root cause of the issue, please call GE Post Sales Service for further assistance.
