SOURCE: UPS problem

Hi,

Based on your post/description, two (2) possibilities:
1. electronic fault - main power/AC mains sensor which could be really just a relay; or
2. corroded fuse terminals or fuse holder.

The first is a bit of a challenge since different brands/models have different sensing circuitry design. Some can be as earlier stated, a simple AC relay while others could be a TRIAC switch with a DIAC trigger. Still, some could be an elaborate AD converter and a myriad of logic circuitry. Often, a service manual or at least a schematic diagram would be needed, however these are not that readily available and most often the tech or DIYer must resort to winging it. This of course would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron. Extreme caution must be exercised since even with 12VDC supply most of the electronics are at least at 60VAC+ level.

The 2nd possibility would be of course be the easiest to determine and repair. Replace/clean.

Should the downtime & repair cost makes the project no longer economically reasonable, perhaps your best bet would be to simply replace the UPS since their prices are relatively low.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

You can also adjust the sensitivity of your UPS so that it will accept the Generator's supply. I had to set ours to low sensitivity to get them to work. Depending on your UPS model, you can either connect to it with the supplied USB cable and run powerchute software to set the sensitivity to low, or some models allow you to adjust sensitivity on the front panel. Good Luck!

SOURCE: I recently purchased a used Belkin F6C800-UNV UPS,

This is normal in some lower end UPS's, the voltage can swing quite a bit, a drop of 40 seems like quite a bit but it's out of the question. It will also adapt to what is plugged in yes. Ultimately to test you would want to try it with something like an actual PC plugged in and make sure it stays running. I'd say otherwise it sounds normal to me.

If it is fully charged a 12volt battery and if it's rarely new should show 13.8volts to 14V.But if the battery is fully charged the open outage will be around11.5 to 12volts again depends on how long itvwas charged previously and usage and under what load that is on connected.

Alarm #191 open cell voltage powerware 9130


Alarm error #191 comes from a battery test, where batteries are put under load for 25 seconds. (If the alarm is unexpected, you might have enabled the periodic 30-day battery test.)

#191 is test failure for battery internal resistance. So, need to locate and replace the bad battery, then run the battery test manually. If batteries are good, make sure no battery connector is corroded or loose.

Why won't new alternator charge battery when car is running


Many cars have a voltage regulator that is integral to the alternator. Check to be sure it is properly connected. One year later afternoon the day before the Turkey was to be cooked I replaced the Alternator. I drove 200 hundred miles and had the car die at the gate to my destination. I failed to properly connect the Voltage Regulator on the Alternator. Look in that direction for a bad wire, fuse, connector.

Hi, Restlessness and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Bank angle sensor tripped and ignition/light key switch not cycled to the "OFF" position and then back to the "ON" position.
5. Security alarm needs a reset.
6. Starter control circuit, relay, or solenoid faulty.
7. Electric starter shaft pinion gear is not engaging or over-running starter clutch slipping.
For more information about your issue, please visit the websites below. Good luck and have nice a day.
