View the Active Alarms

When there is an active alarm in the system, a symbol indicating the alarm level is shown in the top right corner of the screen and the buzzer is active.

From the home screen on the display select Status > Active Alarms. Tapping the display will also silence the buzzer temporarily without login. By logging in and tapping the display, the buzzer will be silenced permanently.
You can now browse through the list of active alarms using the left and right arrows.
Tap the Refresh button to update the list with the latest active alarms.

Alarm Levels

There are three alarm levels:

Critical: Take immediate action and call Schneider Electric.
Warning: The load remains supported, but action must be taken. Call Schneider Electric.
Informational: No immediate action required. Check the cause of the alarm as soon as possible.
