I'm trying to connect a 24V relay and 220V pump using the multi-output, FC, on Huanyang 2.2Kw VFD. Attached is the VFD wiring diagram. I have the FA, FB, FC parameter set to 1 - Run. I can hear the internal relay activate when the spindle turns on, but when I check for voltage, I get no reading across FA, FB or FC and DCM (connected to ground).

Am I checking across the right terminals? What would be the correct ground?

Is it safe to say that I could expect 250VAC across FA? If that's that case, I can power the pump straight from FA.
