The label on the panel side is incorrect for the temperature (it was swapped with flow). Chiller temperature now reads back fine in both the soft (VME) and hard (cRIO) interlocks.</div>

The pressure only reads back on the cRIO though, the voltage is getting to the patch panel. I've tried swapping various cables and slots around and even rebooting the VME crate to no avail. I'm not quite sure what the problem is, but since it is at least in
the hardware interlock I'm not going to spend any more time with it for now.</div>

<p style="margin: 0in; font-family: Calibri, sans-serif; font-size: 11pt;">Hello Brian,</p>
<p style="margin: 0in; font-family: Calibri, sans-serif; font-size: 11pt;"> </p>
<p style="margin: 0in; font-family: Calibri, sans-serif; font-size: 11pt;">Chiller outlet pressure and temperature readings are not correct. The chiller is set at 0 C but outlet temperature is -24 C and pressure -0.2 PSI. Chiller internal temperature reading
is 0.1 C.</p>
