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 alarms occurring 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. TROUBLESHOOTING
The status of the remote unit can be checked via the ION-M Master Unit (for details
please refer to the software manual of the Master Controller). Locally, the status can
be checked at the alarm board, see chapter 5.5 Status LED Alarms.
5.5. STATUS LED ALARMS
For local supervision, an LED alarm board is provided. For layout and detailed
description, please refer to chapter 3.2.2 Alarm Board.
