System Status: UP
Scheduled shutdown: 8 PM, Tues 22 Nov
Systems expected to be back online by early evening on Wedmesday 23 Nov. During this downtime a Transient Voltage Suppression System and an Under-Voltage & Phase Regulator will be installed to help mitigate against problems from the electrical grid. The Variable Frequency Drive on the primary pump will be removed as it has often (for unknown reasons and despite replacement, fixes and reprogramming) been implicated in most of the emergency shutdowns this calendar year. Storage system firwmare on the controllers and disk drawers will be updated. Finally, all the inlet water valves on the TCS racks will be replaced as a preventative measure (two already cracked in Aug-Sept).
