PSL diode chiller broken

Michael R, Rick S, Ollie. P

Our spare diode chiller died over the weekend, bringing down the PSL. We believed we traced it back to a broken water sensor inside the chiller. After removing the part we verified we could not spin the turbines inside it and could not get a signal out of it. We have ordered a new part which should arrive tomorrow. As both our diode chillers are down at the moment, the PSL will remain off until this new part can be installed.
