I recently got (for free) a SpeedAire Model 3Z582 Single Stage, CCW, 3HP, 3 Phase Air Compressor. It has a Dayton motor with the following specs: Model 3N085, 3 HP, 3 Phase, 3495 RPM motor. According to the spec plate, it pulls 8.2 Amps at 230 Volts
I also purchased a Lapond (SoyanPower) Model SVD-ES 2.2KW, 10 Amp VFD in order to run the 3 phase air compressor, but the VFD's manual is written in heavy "Changlesh", and is tough for me to figure out. I am hoping someone in this forum can help me get this thing up and running, but other than connecting my single phase input to terminals R and S, and my 3 phase motor to U, V, and W, I am lost.
I have read enough to know that the pressure switches in my SpeedAire will not like the kind of power that the VFD outputs. So what is the solution? And how can I make use of all the other terminals? It would seem that the VFD could output a low voltage signal, and then receive a signal back to tell the VFD to STOP or to RUN. Am I correct about that? If so, can anyone tell me how to wire and program this VFD to do so?
Thanks so much!
