fluid is new
valve and pump were changed
Soft start is brand new as well.
Not sure what an AVR is but I am going to google it and find out
AVR - Automatic Voltage Regulator. Since 3 elevators share at the same bus, one bad(winding) motor could affect the 3 consequently. Implement an AVR on each motor to isolate one from affecting the others. ( https://youtu.be/BPPuj0mvs88) Have your power supply monitored with a data logger like ( http://www.gfuve.com/power-meter/di...H4tPT4AIVU7aWCh3m4wmCEAAYAyAAEgKCIvD_BwE)

valve is new. Spending all that money without testing? Have you read everything I tested and checked and added to help prevent and pin point this? It was a phase monitor I added before the soft start light is on all the time. Valve is new voltage and amperage is good I did this every time all day while running the car and its matching car 1

I think we need to be more clear, I said voltage monitor too. What I’m referring to is a 3 phase power quality analyzer that, at the very least, records exact voltage over time.

That's what i meant by testing KSNY. A power recorder. Id ltest it for a week. First hooked up to other running elevator on this single power source to see and give a comparison. Then i'd switch feed breakers and power the running car from MR.MELTY's breaker and see if anything changes.

KSNY, Do you have any information on how a bad blocking inverter caused this problem on one car and not the other? Any info on what a blocking inverter is?? Did the building just accidentally find this bad device?

I dont have a clue as to how it was casuing the porblem on one car and not the other. They are on diffent power feeds and when I went and swapped the feed the problem went with it to the other car. I turned off everything relating to the solor panels on the roof and building. Appartently 1 week after that the solar panel guys came and said they replaced the inverter and restored the solar panels. Ever since that both cars have been running fine.

This is what the solar panel guys told me. For all i know they swapped out something else casuing the problem. The building manager was off that day so they dont have the recipt from the techs. Again just what I am told.

Thanks, I appreciate the reply. It sounds like the solar array was sending bad (dirty) power down the line. Is there equuipment in the MR from the solar array, or is the interface done in the Main Distribution Panel? Again, thanks for the info.

Quite the back story on this thread. So does the customer now pay the full bill? You guys lost a lot of $$$ on this one and you’ve got the evidence now to support your claim as well.
I’d be interested to know how this gets handled.

Johnny Next to the motor room in the main electrical room where everything power related in the bulding goes. not sure if that helps

I’d be interested to know how this gets handled. Its a very large account with over 100+ elevators under contract. I am sure we lost money on it But thats above my pay.

The Siemens ss records the incoming side and motor side voltages at time of fault. What did it say? This was 2 years ago. But the car was littery just sitting there not running and burnt out the motor. The voltage was 480in/out (maybe a 2 volt diffence from line to line). The soft start was added after the 2nd motor. amps was 000 000 000
