Corner Chilled water pump trip

Strange - another chilled water pump trip - this time in the corner. CWP3 VFD unit tripped. I reset the 480volt circuit (pushed the reset button, did NOT cycle the breaker).

The pump started up with no issues. Currently I have left the system with two CWPs and their associated chillers running. Both CWP1 and CWP3 are running. I happened to be in the control room when Jeff reported an alarm The LVEA is recovering from a ~0.5 F temperature excursion.
