PM8000 Alarm Acknowledge

[Hyeontae-Song]

Is it possible to delete past alarm history from PM8000 meter?

If I Acknowledge Alarm for PM8000 in Power Monitoring Expert, can I make Alarm Acknowledge applied to PM8000 Local Device? (automatically applied)

Best Regard.

Hello @Hyeontae-Song ,

To your second question, "can I make Alarm Acknowledge applied to PM8000 Local Device?" The answer is no.

The first question about "delete past alarm history" is a loaded question. The event log on a meter can be cleared, the front panel alarm log cannot. Easiest way to clear a meter's event log is to change the depth, changing this number will clear the log.

It's worth noting that the term "Alarms" in the context of PME is a separate and distinctly different list from the "Alarms" visible only on the front panel display of the PM8000.

The list of "Alarms" visible in PME are maintained in the PME database and are (mostly) comprised of downloaded EventLog entries from the PM8000 (and the EventLogs of other devices connected to PME).

The list of "Alarms" visible on the front panel display of the PM8000 is a list separate and distinct from the meter's EventLog (though most Alarms usually have one or more corresponding Event entries). The list of "Historical Alarms" and "Active Alarms" visible only on the PM8000 display can only be acknowledged via the display interface on the respective screen.

The list of "Alarms" visible in the PME database can only be acknowledged with PME.

Hi @Charles_Murison , 

But why we cannot clear/empty "historical Alarms" display as shown below image? Those alarms surely get stored somewhere in the ION Modules. What's the challenges we cannot clear all historical alarms on Front display.  
I tried to check in ION Setup (advanced mode) for all modules but did not find where those historical alarms exist. Is it inside the meter onboard memory which cannot access via ION Setup>modules ?

Hello @AbhaySingh ,
You have a loaded question. The event log is controlled by the event log controller module, this module has very few setting registers, depth and threshold. If you change the depth, the meter will need to change the memory therefor you will clear the event log. The front panel historical alarms are not the same as the event log. The historical alarms are in a different section of memory that you cannot access via ION Setup or ION modules.
