5. Alarms
5.1. Bite and Alarms
The Built-In Test concept comprises the monitoring of the power supplies, the power
amplifiers and the optical interface.
All occurring alarms can be checked via software at the master unit.
5.2. Handling of Alarms
As soon as the software acknowledges a valid alarm, a message is transmitted to the
master unit.
If the reason for the alarm has been cleared or if the alarm should continue, a new
alarm message will not be repeated. If there was an interruption of at least five
seconds after acknowledgement, a new alarm message will be generated.
5.3. Alarm Status
For details refer to the corresponding software documentation of the master unit.
5.4. Status LED Alarms
For local supervision, a status LED on the connector flange of the remote unit
provides a visual indication of possible reasons for alarms. This table shows possible
on-site measures that could be checked before referring to the master unit alarm list.
For local supervision, a status LED on the connector panel of the remote unit
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.
