Alarm severity is used to identify the severity level, significance and urgency of an alarm.
Table 1 shows how to handle the alarms of different severity levels.
Alarm severity |
Definition |
Handling |
|---|---|---|
Critical |

Should be handled immediately. Otherwise, the system may break down. |
Major |
Refers to fault alarms and event alarms of boards or line in local parts. |
Should be handled timely. Otherwise, the important functions will be affected. |
Minor |
Refers to general fault alarms and event alarms that indicate the operating status of boards or line. |
Such alarms are used to remind the maintenance engineer to efficiently locate the alarm causes and eliminate the possible faults. Warning Refers to fault alarms and event alarms for warning. |
You can take different measures for alarms of different severities. On the U2000 Web LCT, you can redefine the severity level for an alarm as required. You need to adjust the severity for an alarm only when the alarm has severer or less severe impacts than when it is at the original severity level.
