4.3.2. Status LED alarms
For local supervision, a status LED on the connector panel of the Extension Unit
adjacent to the Expansion ports provides a visual warning of an alarm condition. The
color of the LED indicates the severity of the alarm. Detailed alarm information is
available through the ION-U software interface. This table lists the alarm conditions
and possible on-site measures that could be performed to resolve the issues
responsible for triggering the alarms.
