    All, I just received 6 new RS 1500's and none of them will come on line...will only stay on battery. Yes, I've checked that the battery has been connected and they are plugged into power. I do have a fairly unique situation where the line voltage is within limits at 124.5V, however the freqency of the line voltage is 45.5Hz. This has to do with the fact that my main power is 220V 50Hz and it is stepped down to 110V. I have been using various APC UPS's for years in this facility and have never had a problem....I've loaded the PowerChute software and all it does is tell me that (1) yes there is line voltage present and (2) yes, it's on battery. I've also played with the sensitivity with no results.

    Any ideas?

    The input frequency of 45.5 is outside of the +/- threshold for the UPS to operate online. Unfortunately, the only options would be to somehow fine tune the output of the transformer to adjust the frequency of the wave, or put a device in between the transformer and UPS's that would accomplish that.

    I had a feeling that this was the issue......Any idea of the input frequency limits?

    Should be 47-63 Hz.

    I also have an issue with the RS1500 not coming on-line. I have one that is about 6 years old. I have had no problems with it for all of that time and have not replaced the battery. Recently it switched to battery and started beeping but the "Replace Battery" light is not on. When I restart the unit, the "on-line" light blinks and then quickly switches to battery and starts beeping again. I tried a different power outlet but received the same results. I unplugged the battery and tried to run only on utility power but "on-line" still blinks and tries to switch to battery but can't find it since it is unplugged. It then tries to switch back to "on-line" for a microsecond and then back to battery. After a couple of tries the red overload light flashes then go back into it's cycle again. I have held the front power button in until all of the lights flash and that doesn't help either. This unit hasn't moved and has worked fine in it's location until now.

    Serial # is JB0420020008

    Brent,

    Whenever you turn the UPS on the first thing that it will do is run a self-test. It boots up the UPS to online and switches to on battery to check the internal battery. If the battery bad, the replace battery LED should lit up solid. If it has detected that the battery is disconnected or it cannot detect the battery it would show a flashing replace battery LED. You've said that the unit is producing a tone, can you tell us if there is any pattery with the beep/ tone? Was there an accompanying LED that is flashing/ solid while the tone is on? Was it a continuous tone, chirping or you can hear beeps?

    By any chance do you have a spare RS1500 where we can swap the batteries?

    Thanks for the response. Yes it runs it's automatic self test, but then can't click back to utility power successfully.

    Here is the sequence:

    With Battery Plugged In
    1. Turn on power, one quick chirp
    2. On Line LED flashes green sixteen times
    3. On Battery LED lights solid yellow, fan comes on, On Line LED continues to flash another sixteen times
    4. On Line green LED goes out, On Battery LED stays on (solid yellow), System beeps four times
    5. For a microsecond the yellow On Battery LED goes out, the green On Line LED comes on then goes out again and the yellow On Battery light comes on again and beeps four times.
    6. The system will pause for a second or two at most and then repeat step #5.
    This continues indefinitely


    With Battery Unplugged
    1. Turn on power, one quick chirp
    2. On Line LED flashes green eight times then goes out
    3. On Battery LED lights solid yellow for half a second then goes out, system beeps once, fan comes on
    4. For a microsecond On Battery yellow goes out, green On Line LED blinks once then goes out, fan spins down, On Battery yellow comes back on solid and system gives and extended beep
    5. Step four can repeat any where from 1 to 4 times
    6. Overload red LED comes on and blinks back and fourth with On Line green LED for a couple of blinks
    7. Change Battery Red LED will then (sometimes) come on momentarily then go out
    8. Then it goes back to step 4
    This continues indefinitely

    I do not have another 1500 to use for trouble shooting.

    My first thought was a bad battery but if it cannot run on utility power then it may be something else.

    Brent,

    Do you have the APC PowerChute Personal Edition software installed on your PC? If the UPS switches from Online to OnBattery and vice-versa it is possible that the unit is detecting power disturbances on your outlet i.e. low/high voltage, brownouts and distortion. We can adjust the sensitivity and transfer points of the unit using the APC software and or using the front panel buttons of the unit provided. You can check this out on the UPS user's manual.

    Having the exact same issue as Brent. The unit started going on battery even through I can plug the same equipment into the outlet with no problem. Reset button has no effect. It is now just sitting there beeping (incessantly) with the yellow light on.

    I am having the same problem as Brent, as well.  I know this is an older model but it was working fine until I changed the batteries.  I don't have APC PowerChute Personal Edition software installed and since we have had it a while, I don't have any disks with it.  Is there a place to download it?

    I will say, I called the Tech Support people today for some help and after a few tests, he pretty much told me I needed a new UPS. I thought I would check you folks out first!!

    Any help is appreciated!

    Hi,

    Did the tech ask you to brain dead / reset the UPS? If so and it still is failing then the unit does need to be replaced. 

    To brain dead / reset the UPS

    1: Disconnect any attached load.

    2: Unplug the UPS from the wall socket.

    3: Disconnect the UPS' internal battery.

    4: Push and hold the "On" button on the UPS for 5 seconds

    5: Reconnect internal battery.

    6: Plug UPS in to known good power source.

    7: Turn UPS on.

    One more the same device with this symptoms from me.

    Brain dead / reset doesn't help.

    Can you please tell us some direction of thinking of repairing?

    Thank you!

    Hi'

    I had this problem and scrapped a few of these unit, however i had one this week and i installed power chute and then set the sensitivity to low and the unit went on line , i did many off and on and all is well, so maybe you can try that'
