Huanyang GT Pressure switch connection?

Hello everyone,
Need some guidance please. I'm setting up a new Quincy air compressor QT-7.5HP. Please review the attached pictures from manual. It's all wired up to a new Huanyang GT 7.5KW and runs fine from keyboard. I know other persons have wired control to the pressure switch but not quite sure which 2 terminals to connect. Can someone lend some advise here!

Thanks in advance

Steve in Maine and it's snowing!!

It would be S1 and Com this can only be a switch with no voltage, so check the pressure switch that in the closed position there is no voltage across the 2 connections of the switch

You will then have to change a Parameter for remote control

P0.01=1 this may need to be 2

P05.01=1

Any chance you can forward your parameters? I am doing the same Pressure Switch wiring and those 2 parameters aren't enough to get anything to happen. Thank you!

Are you using the same VFD Drive and what are your motor specs
