Off-line(also called standby) UPS, it remains idle until a power interruption occurs, which it then switches from utility power to its own power source. On the other hand, double conversion (also called online)UPS continuously gives power from its own battery and then replenishing the power instantaneously through the AC power from the socket...

We had a power outage for about 45 minutes a few days ago. Ever since then the Powerware 3110 has been beeping. I turned it off and left it plugged in overnight and when I turned it back on the beeping...


This could be several things, fortunately the device should actually be helping you to diagnose the issue. There are different beeps for different issues. They are as follows:

1 Beep Every 5 Seconds = Power Outage\Loose Plug Connection\Tripped Circuit Breaker\Power Cord Damage or Failure

2 Beeps Every 5 Seconds = Low Battery Alarm

3 Beeps Every 5 Seconds = Battery Needs Charging\Service\Replacement

3 Beeps Every 5 Minutes = The Battery is discharged and battery power is unavailable (If this continues battery replacement may be necessary)

1 Beep Ever 1/2 Second = Power Requirements exceed the UPS Capacity (remove some equipment to lighten the load on the unit)

Continuous Beep = Short Circuit / Input Voltage out of Range / UPS Fault (Likely replacement of entire unit)

That should help diagnose the actual issue. If it turns out the battery needs to be replaced they can be found online for around $20. A simple google search for Powerware 3110 Battery should return what you're after. Good luck!

Infinit loo between online and on battery?


With all 5 units behaving the same, I would expect that the power is still out of range. If the power is too high or too low (see manual for thresholds) the unit will stay on battery power to protect the attached equipment. If you have the software loaded, it will show you what the input AC voltage is at. Otherwise, it could be time for new batteries: http://batteryinternational.com/apc-smartups-1000-ups-battery-ups-batteries-f2.html

Infinit loo between online and on battery?


shady545, If units have batteries older than 3 years of age, they may need to be replaced. I suggest you evaluate each unit one by one and try swapping in a new set of 12v 12ah or 18ah fully charged batteries to see if that will clear-up the problem in at least one unit. I had to replace both batteries in my APC1250 when one battery developed a shorted cell. Let me know what you find out with your units. 12fixlouie 30min north of Windy City

Our online UPS is giving only about 204-206 volts, instead of 240. I changed the batteries, but the output voltage hasnt changed. What could be the problem? Could you suggest some things I can try?


oh that voltage is ok if you are measuring voltage by digital multimeter then it shows wrong value measure voltage by anologue multimeter it will show 240v correctly dont suspect on measured voltage

How to turn off Compaq R1500 UPS System?


Press and HOLD the power button on/off..until the unit goes into the standby mode...unfortunately there is not a switch on the back of the unit so you are required to literally unplug the unit...which will completely power down the unit.

The monitor goes into power save mode and the ups disconnect


It should work, make sure each profile is set the same way. Keep in mind you should still be able to utilize your standby feature, and your screensaver as well.
