Been a long while since I’ve been trying to troubleshoot manufacturing equipment. Up on a rooftop trying to figure out why a damper don’t wanna move. Waiting for the guy I’m helping to bring up some tools. The good thing is, there’s only so many things it can be, shouldn’t take long to narrow it down. Already verified the 4-20 loop is putting out the mAs. It seems the actuator has its 120Vs.
