Subject: RE: Raven NH3 cooler troubles. On/off valve won't open.

Thanks for the suggestions. We ended up just manually opening the on off valve and disconnected the mechanism so it couldn't shut off. Was able to run for a little while today. The flow control valve will shut the system clear off when we stop. It does take it a few seconds to open all the way up, so I don't like that it takes a bit to be putting on the full rate. Still waiting on my Trimble man so we'll see what happens there. I'm pretty sure since I never see a change in voltage to the valve that the signaling electronics are malfunctioning. But I'll have to admit that I'm a little out of my league on the diagnosis here.
