Chilled water pump at End Y tripped
I just received a call from Cheryl in the control room saying the chilled water pump at EY was in alarm. I looked at the screen and chilled water pump #1 had tripped. I started pump 2.

Chilled water pump 2 did not appear to allow the chiller to start so I cleared the fault on pump 1 and restarted pump 1. The water temperature is now falling. I will continue to monitor.
