Occasional solid tone with red and green flashing LED.

[Anonymous user]

Hey folks --

We have an ES 350, just bought in January. Two or three times now it's gone into panic mode (my term), sounding a constant tone with its single LED rapidly alternating green and red.

At least once it stopped on its own, but this last time (today) I had to shut down the machine (Mac Pro tower, 30" Cinema display) in order to turn the UPS off. With the machine still off, I turned the unit back on -- solid green, no tone, no problems. Turned the computer back on, still fine.

I don't have anything else attached to the battery outlets other than the tower and monitor. Everything else plugged in to the surge protector (an old PC with small monitor and a desk lamp) were all off, throughout.

I have a suspicion it's the outlet. Can I confirm that somehow? Thanks in advance!

is this the unit? http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BE350G

it only provides 200 watts which seems undersized for what you have plugged in.

upon looking at the user's guide that has the LED indicators listed, (on the documentation tab of the page I provided), http://www.apcmedia.com/salestools/EALN-7CEQDH_R1_EN.pdf , it appears this issue is telling you that there is an issue with the battery on the unit. i would suggest and double check what i am reading to make sure it matches up with the symptoms.

if that is the case, i am wondering if you can let the unit sit for at least 8 hours, assuming you've had no power issues to drain the battery already, and then plug in a non critical load such as a lamp to the battery back up outlets, then do a pull plug test to see if the UPS successfully transitions to battery power and keeps the light on. if not, it'd indicate that there may be an issue with a battery here or the battery connection (which I'd check just incase). if it does work, and only does this with the computer attached, then it might be an issue with when the UPS tries to go to battery on its own, that it is not charged and is telling you its a low battery or its charged and gets depleted very quickly with your tower/monitor connected.

Hi --

yes, I think that's the unit (it's kind of a pain to get under the desk, so I can't check the exact model number to be positive) -- and in the documentation you linked (thanks!), it does appear that my symptoms are battery-related. I just don't know why it would self-correct, especially just by being powered-down and then immediately powered back up.

You're right about the wattage probably being low, though. Didn't take that into consideration.

If no one else has any ideas about the intermittent nature of this then I'll mark it as "answered" -- but I'd like to let the question hang out here for a day or so. Thanks!
