PSL tripped
The PSL is offline again. Seems the chiller tripped again. XTALTEMP started rising about 5 minutes ago.

We went to the chiller, in the upper chiller we see no water in the tube where you fill the water. The display says Outlet temperature 20.7C setp: 20C, and cycles through error messages: flow senor 1, conductivity too high, level low.
We saw some water on the floor about 1-2 cups of water. Some photos that show where the water was are attached. We wiped all the water up that was outside the chiller, but didn't reach in and around the cables to dry up inside the enclosure. The gray canvas in the back seems completely dry.
