<p>I got a call at 5:15AM saying that an ECal alarm had gone off and that one value had briefly gone to 0 and then returned at a higher value. When I logged in I found the left pump pressure had increased from its usual 11.1 to 12.8. I tried a soft reboot from NIMax but wasn't sure which channel controlled the pumps. I tried cRIO5 and that did nothing. cRIO6 did the trick and the pump readout went to 0. However, when the readouts turned back on, the left pump was still elevated as before. I did a hard reboot of everything by cycling the power and when everything came back on the left pump pressure was back to its usual 11.1. I'm not sure why the soft reboot wasn't sufficient. Since it was only the left pump pressure that was faulty, it was not likely due to a cRIO expansion chassis and instead due to the pressure sensor itself. My guess is that cycling the cRIO didn't power cycle the sensor.</p>
