Power wave 9155 10kva ups is shuting down when power failure time and it is not switching on when again power came back

Yamaha 4 stokes wont fire back up if you try to restart within 1 second of shuting it off.

Get a professional diagnoses on the set. My first guess would be a defective main board but issue could be power supply related as well.

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit won’t deliver power when the mains supply fails.

hello,

pLease try to back up your data in your laptop then repair or reinstall your operating system to replace the corrupted or damage files.

Thanks

SOUNDS LIKE LAMP IS GOING OUT.

put ink cartridges in the printer

That is a print head tilt or axis failure.
There are 2 problems that cause that 95 percent of the time.
1 is a stainless steel pivot block on the left side frame that gets filled with overflow ink. Needs cleaned.
2. The print head wiper blade is stuck to the print head due to shuting it down improperly or a power failure.

HI there

This is a faulty Mainboard that will need either repair or replacement.

If a Projector starts playing on and off tricks I have found it to be 99% of the time a faulty Mainboard.

Done

I have the same problem. The clock changed to military time after we experienced a power failure. I have tried to correct it by holding down the "Alarm Set" button and hitting the "On/Off" button at the same time. It works while the buttons are pressed but immediately reverts to milirtary time. Any other suggestions?
