Air Assist - Ruida 6442 Voltage issue

[Chad Tennant]

Hello,

I have installed the Super Ultimate Air Assist on my laser unit, and it was working great. I however was fiddling with something, and now the relay will not turn off when either the manual override is turned off to automatic mode, or when the project is done lazing.

I am finding that the relay coal is still receiving 12 volts after I turn off the manual override or the end of the lazing project has completed.

I checked the board, and I find that there is a 12 volt potential between the Status and Wind pins. Is that normal? I don't think so. If anything, I would think it should be 0 volts.

So, did I break something? I have checked the wiring, and everything seems to be properly connected, but is there a short somewhere?

Much appreciated.

Chad

One last thing.

I get a voltage of 12v from status to ground, and a voltage of 24v from wind to ground.

The wind terminal normally makes a ground and I believe the UAA solenoid uses the 24V+ on the same connector with that to operate.
