5. Alarms 

5.1. Bite  and  Alarms 

 

The Built-In Test concept comprises the monitoring of the power supplies, the power 
amplifiers, fan units and the optical interface. 
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 Remote 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 Remote 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.
