5. Alarms
5.1. Bite and Alarms
The Built-In Test concept comprises the monitoring of the power supplies, the power
amplifiers, and fan units.
All occurring alarms can be checked via software at the Master Unit.
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.
5.2. Troubleshooting
The status of the Extension Unit can be checked via the Master Unit (for details
please refer to the ION-U Site Manager software manual). Locally, the status can be
checked at the LED.
5.3. Status LED Alarms
For local supervision, a status LED on the connector flange of the Extension Unit
provides a visual indication of possible reasons for alarms. The color of the LED
indicates the severity of the alarm. Detailed alarm information is available through the
ION-U software interface.
