Had a power outage and when generator kicked in, all of my APC BACK-UPS NS 600 continued to run on battery. Outlets all had power, but the UPS' beepings indicated that they were not getting power.
Also, have some Tripp-Lites. Their indicators said they were getting power but they all eventually consumed their battery and shut off.
Once we came off generator everything started working again. I should think this has something to do with the power generated by my generator. Anyone know what the problem could be?
Thank you, bwajay

a lot of generators put out "dirty" power so the UPS runs on battery if it doesnt like it.
the first thing to do would be to adjust the sensitivity on your UPSs because by default they are set to "high" so they will go to battery if they see any problems with the generator power. The other settings are medium and low.
Unfortunately, on this unit, in order to lower the sensitivity, you will need to install PowerChute Personal Edition on a computer and attach the USB to RJ-45 data cable provided with any Back-UPS and adjust it that way within the software.
Here is a link to the software: http://www.apcc.com/tools/download/index.cfm?isocountrycode=US&tsk=
From there, you can choose software upgrades - powerchute personal edition and choose your operating system to download.
