Unaknowledgeable Alarms in 800xA with AC450
I used 80xA software with AC450 controller
I faced a problem that some Alarms Cannot be Aknowledged and Still Blinking
I checked that the alarm has gone acually so it must be able to aknowledged but when i select it and press Aknowledge it still blinkning as its still coming
any solve for this problem?
What is the System version and revision?
Are these alarms are old alarms which are reapperaing in the system again ?
Refer the field alert - "3BSE067108_-_en_ALERT_-_System_800xA_Operations_SV5.1_RU1_An_Alarm_List_may_pr
esent_wrong_information.pdf" which is same issue you faced?
Also check the user who acknowledge alarm is a member of Operators Group.
Check the Time synch between the controllers and system.
If you still coudn't manage to fix the issue,please contact your regional support center for further assistance.
If you are at the versions ABB 800xA Base 5.1.0 RU1 (aka 5.1 Rev A)
or ABB 800xA Base S-FP 5.1.1 (aka 5.1 FP1) you must install a temporary correction (see previous post) to prevent alarm list from presenting incorrect information.
In case you can't figure out what the problem is, I suggest that you ask your regional ABB support center to file a support case and have it escalated to Sweden.
