• Slow flash. Alternating between the off state and the on state one time per second.
In the event of an alarm, the page containing the alarm will be promoted to active page. If
there are multiple pages with alarms, the page with the lowest page number is promoted.
If there are alarms on multiple pages, and alarms on some pages have already been
acknowledged (but not cleared) by the user, then the pages with active alarms move ahead
of the pages that have acknowledged alarms. The user will always have to navigate
through the pages of alarms to view them.
Display of alarm pages is prioritized according to active window (unacknowledged or
flashing alarm) and page number (for example, if two pages have an unacknowledged
alarm, the page with the lowest number will automatically be promoted as the displayed
page).
The self-test page displays any active self test alarms as well as the time of occurrence
and the severity of the alarm (yellow for non-critical and red for critical).
The product information page contains all of the constituent data describing the makeup
of the IED, including the order code and serial number of the IED, in addition to the device
identification name, the setting configuration name, the time of last change, the firmware
version, and the firmware release date.
