I have a Symetra LX 16000 and tonight I got the following event that occurred and disappeared within seconds:
|10/04/2022||20:24:32||UPS: Returned from temporary bypass.|
|10/04/2022||20:24:24||UPS: In temporary bypass.|
I'm looking at the logs and I don't see any reason why the UPS decided to go into "temporary bypass" There are no alarms and the UPS is OnLine. The UPS is lightly loaded:
|Phase L1||Phase L2||Phase L1/L2|
|Input Voltage||121.1 VAC||121.1 VAC||209.5 VAC @ 59.99Hz|
|Phase L1||Phase L2||Phase L1/L2|
|Output Voltage||121.1 VAC||120.2 VAC||211.3 VAC @ 59.98Hz|
|Output Current||09.4 Amps||13.4 Amps||---|
|Output Load kVA||01.13 kVA||01.68 kVA||---|
|Output Watts at n+0||015 %Watts||026 %Watts||---|
|Output VA at n+0||012 %VA||018 %VA||---|
If someone could directly to information regarding this event it would be appreciated...

Thank you for reaching out to the SE Community, my name is Jon and I will assist you with this query. I am sorry to hear about the issue that you are having.
From the PowerView/LCD of the UPS you'll be able to view what are the events that the UPS has captured. You can press the ESC key and navigate to Diags > Faults and Diagnostics and also Logging > View Log.
Downloading the NMC log files can also help us further diagnose on what has happened on the UPS.

I've DM'd the images and log file to you. Just so your aware, I've disconnected the 3rd and 4th Runtime frames and removed any batteries from the frames that were older than 2018. I also re-seated the power modules as per a suggestion from Schneider. These events will show up in the event log.

No there was no disruption thank goodness. The temporary bypass only lasted 8 seconds and the line power was in place so there was no outage. What concerned me was what caused the UPS to go into temporary bypass? Thank goodness there was no power outage that just may have happened at the same time.
I have noticed that in Frame #2 there are negative signs in-front of the raw battery data. Can you decipher what this means? I reached out to Schneider to attempt to diagnose the possible issue. They suggested pulling any of the batteries that were older than 2016. Disconnecting the XR frames that no longer had batteries in them, and to reseat each power module. I did all of that but I’m not sure any of that may have resolved whatever issue caused the UPS to put itself into bypass.
