7.5 General faults & error messages
An ALR-sentence is used to indicate a failure or malfunction that will significantly reduce
integrity or stop operation of M2. The Alarm messages generated are IEC61162-1 compliant
“$AIALR”-sentences on the Presentation Interface output ports.
The parameters of this sentence are:
Time of alarm condition change (UTC)
Unique alarm number (identifier) at alarm source
Alarm condition
Alarm acknowledge state
Alarm description text
and are set according to the table following.
The "alarm condition" field is set to "A" when the alarm condition threshold is exceeded, and "V"
when the alarm condition returns to a level that does not exceed the threshold. A continuing
healthy status “V” is sent out at 1 minute intervals.
NOTE: When all alarm conditions are healthy, a special single message is sent at 1 minute
intervals.
