    I learned a long time ago to never argue with a fool, people will not know the difference. Actually, the three lead motor currents were measured several weeks ago and were presented to the...

    this did not cause the other compressor failures...as I said it will take a long time to describe all the alterations that we have done to fix this system. Some techs are good some just want to sell...

    typo it is a 60 hz 240 Vac system, the model number is ZR61 PFV 950 if my memory serves correctly, in any case thanks for all your suggestions
  4. type 240 vac

    type 240 vac
  5. yes it is 60hz 3540 Vac but more importantly ...

    yes it is 60hz 3540 Vac
    but more importantly

    FIXED !!!!!!!!!!!!!

    First I want to thank everyone on this board who gave constructive ideas. As most of you know, when you are dealing with a...
  6. I agree,,,,, my calculation show that this should...

    I agree,,,,, my calculation show that this should be maybe 2-3 amps to a maximum of 7 amps depending on voltage drop across the capacitor (which I will measure) using the following formula one can...
  7. yes this is the run capacitor...I may have read...

    yes this is the run capacitor...I may have read the meter incorrectly but that is it...what do you think it should be
  8. thanks for the suggestions.,....on the electrical...

    thanks for the suggestions.,....on the electrical issues...we installed new capacitors, and start relay, in any case, the measured current on the capcitor leg is only about .5 amp....a permanent...

    yes we lowered the charge a little but it is supposedly where it should be thanks
  10. CPR Valve update We adjusted the CPR valve to...

    CPR Valve update
    We adjusted the CPR valve to see if it would lower the motor current. Lowering the suction pressure to 40 psi did lower the current but not to the compressor manufacturers value....
  11. actually I am qualified and I am working side by...

    actually I am qualified and I am working side by side with the contractor that put the system in...so if you know something that we are missing you could point it out
  12. you are correct...but I am also a ham radio...

    you are correct...but I am also a ham radio operator and an over the road truck driver at one time...I know which end of a soldering iron to pick up.... I designed this system to a large degree...or...

    I am a licensed professional electrical and nuclear engineer with extensive expereince.

    the more we look at it it appears the CPR valve is the problem see this link

    will let everyone know if this is the...

    we can actually measure the discharge pressure in several places in the piping...the discharge pressure is a good reading....but you do have a good point...I have seen this problem before but more...
  16. technically you are correct, however, the voltage...

    technically you are correct, however, the voltage at the disconnect is effectively the voltage at the motor in this case ,..there is 3 ft of copper wire from the disconnect to the starter, 2 feet...
  17. not sure what that means....we did some more...

    not sure what that means....we did some more checking last night...the CPR valve may be an issue but too soon to say....also we probably do have too much R22 in the system and we are removing...
  18. voltage reading was taken at disconnect which has...

    voltage reading was taken at disconnect which has about 5 ft of lead before the motor...no voltage drop in this short run
    amp reading at disconnect and at starter...no interference (we thought about...
  19. we are sure of the wiring and capacitors...one...

    we are sure of the wiring and capacitors...one idea we have is that perhaps we have too much charge (R22) in the system. We are going to try taking some out and see if that makes a difference.....
  20. that is a good idea...the CPR valve is set at 75...

    that is a good idea...the CPR valve is set at 75 psi....since we were getting suction pressure below this (65 psi) and still high current it does not seem that this is the problem ...I have asked...
  21. answes2

    There is no restriction where the pressure (suction and discharge) is measured there is a high pressure switch (~400 psi) that has and will trip unit if we get to 400 psi...the pressure taps are...
  22. voltage

    good question probably should have noted it was 237 Vac which is more or less the rated voltage for the single phase (240 v) compressor
  23. Scroll Compressor draws about 10 amps more than it should

    More on the saga of my ZR61 single phase R22 compressor problems with my geothermal system. In summary the compressor is drawing about 10 amps more than the table (curve) shows at every operating...
