APC BE750G

[Anonymous user]

The subject UPS has been acting up lately.When I would press the main power button,the green LED would flash  several times,and the unit usually switched on,with a solid green LED.Today that changed,and after flashing multiple times,the LED turned off,and the unit let out a non-stop tone.Repressing the power button produced the same result.I tried a new battery,but that didn't help,and I got the same response.The circuit breaker wasn't tripped,I checked.The unit was made in 2007,so it is well outside warranty.Does anyone have any ideas,or has it just died of old age?

Thanks

Hello again,

I still had the user's guide open and you can either enable/disable Master Controlled outlets completely OR change the threshold settings. So you could try changing the threshold by using the steps outlined in http://www.apcmedia.com/salestools/KBOK-766PMZ/KBOK-766PMZ_R2_EN.pdf or just turn Master Controlled outlets off completely.

Did you recently connect anything new to the UPS receptacles? Does this still happen with nothing plugged into the UPS?

I am referring to this user's guide: http://www.apcmedia.com/salestools/KBOK-766PMZ/KBOK-766PMZ_R2_EN.pdf

Could you review that and let me know if the symptom you think you're getting on page 2 could be the overload shutdown symptom (regardless if it really is an overload or not I am just trying to understand the visual and audible symptoms)?

Hi Angela: Thanks for your reply.No,I have not plugged in anything new.The problem started a few months ago,when I would turn the UPS on with the power switch.Occasionally,after flashing green several times,the UPS would shut down,and the green led indicator would turn off (and the audible steady tone would start). I then would press the power button again,and the green led would flash and eventually would go to solid green,and the UPS would stay on.Yesterday,I couldn't get the UPS to stay on at all.Yesterday,I installed a new battery with no load,and the UPS would still not start.For years,I have been in the habit of shutting off the UPS after I shut down my computer at day's end.BTW,I have never used the "Master Enable" feature,nor have I installed the PowerChute software,if that makes a difference.Reviewing the PDF you gave the link to does not seem to deal with my specific issue.Thanks!

Typically, I'd recommend you just leave a UPS on all of the time maybe besides when you are away for long periods of time and so that the UPS does not run down during a power outage.

Anyway, I also asked someone else earlier today who thought it could be a faulty unit but I wanted to see what you said regarding my original questions.

With a new battery, the only other thing I may do is ensure you leave it plugged in for a few days to charge (even if the unit is off) and re-try.

If nothing pans out, you can also review www.apc.com/recycle for recycling or Trade In options if you are interested in a replacement of some type.

Hi Angela: I really appreciate your interest! I should have mentioned I broke down and bought a new APC ES750 last night.I will try leaving the old one plugged in to make sure the new battery is charged,but the vendor I got it from said it comes charged.I will also keep the new UPS on when I shut down my computer for the day.One other thing: I had the Master Enable "on" on my new UPS,but when it kicks in,it kills the wireless router plugged into the UPS when the UPS goes into power saving mode.Is there some way of bypassing the Master Enable feature for my router,besides plugging the router directly into a nearby power bar?

Thanks!

I think I will leave the Master Enabled feature off,as that way,my router will still run when I turn off the desktop,and the router will still be protected from spikes.I leave the router powered up as I can then use my tablet.My printer and scanner are the only other things connected to the UPS,and they are both normally off.I can live with any parasitic losses,lol!

Sounds good!
