Constant alarm but works fine otherwise


Jordan,

It probably burned up one of the capacitors on the board that signal the UPS to turn the alarm off. I've had this happen before and I unplugged everything, turned the UPS off, disconnected the batteries and then opened the UPS up to cut off the tiny, annoying, surprisingly loud speaker. I then put everything back together and that was the end of it :)

GE LP33 UPS inverter failed to start


Dear Yared,

Did you try to give the UPS some time to recharge the batteries?
Seems like the batteries have reached their cut-off voltage and are not supplying enough voltage to the inverter.

Normally the dc boos circuit of the UPS will supply voltage to the DC BUS so maybe the problem can be found in the dc boost circuit or BUS if recharging the batteries is not helping.

Let me know.

Best Regards,


Ron

I connected 8, 100Ah battery with APC 2.2KVA inverter, now it doesnt give correct battery indication and keep producing beeping noise, whats the problem?


Continuous Beeping (theamber On Battery LED will be illuminated)
This alarm indicates that the UPS has reached aLow Battery condition and will soon shutdown. The UPS can only operate onbattery for a limited amount of time. In order to protect the unit's batteriesfrom discharging too much, the UPS will shutdown and turn off its output. Towarn you that the unit will soon shutdown, the UPS will sound this alarm 2minutes before actual shutdown. With optional Powerchute Plus software, 2minutes can be changed to 5, 7, or 10 minutes to give you more of a warning ofimpending shutdown. If you hear this tone, you should immediately gracefullyshutdown your operating system to prevent data loss or corruption.
Note:This graceful shutdown will occur automatically if Powerchute PLUS software isbeing used.

Constant, Solid Tone (the red Overload LEDwill be illuminated)
This alarm indicates that the UPS has detectedan Overload condition. If this alarm is sounded, try removing non-essentialequipment. The alarm will remain until the load is reduced. To determine ifyour UPS is capable of handling the equipment you want to protect, visit APC'sSizing Guide at www.apcc.com/sizing.

Continuous Beeps for One Minute; RepeatedEvery 5 Hours (Replace Battery LED will be illuminated)
This alarm indicates that the UPS has failed itsSelf-Test of the battery. The unit will continue to sound this alarm until theunit passes the test. Try to let the unit charge for a few hours and thenperform another Self-Test (Press and hold the on/off button until the second'chirp', then release). If it fails and the unit is still in-warranty (twoyears from date of purchase), then contact APC. If the unit fails and its outof warranty, then order a replacement battey cartridge through your reseller,distributor, or from APC's web site.

If the device was still under warranty, you should call APC support and ask to send it in for repairs or replacement. Just keep politely asking, and ask to talk to their superior whenever they say it isn't possible and eventually you will get an RMA ticket/number.
If the device is not under warranty, you might be able to convince APC to service the device for a fee.

Looking to silence the low battery alarm on a belkin F6C120 but not the overload/fault... when power goes out, the constant beeping from several of these makes staff go crazy.... Thanks.


Why not replace the speakers/buzzers with Ultra Bright LEDS with an appropriate resistor in line

That way they get to see a fault and keep their cool

1) Switch Off the UPS and unplug all Loads (like System, Monitor etc.) from UPS.
2) Switch Off the AC Power (Input Power to UPS).
3) Press the UPS Power Switch constantly unless you hear 2nd BEEP Tone. As soon as you are hearing 2nd BEEP Tone, Release the Power Switch.
4) This is COLD START of all APC UPS that will reset any internal problem.
5) If, however, the problem persists, contact APC.
