Southwest Linac Zone 24/26 level alarm. 26 Emptied.
South Linac Modules 24 and 26 both saw their JT valves go closed despite CAMAC commands to open at 0125 this morning. CAMAC EV cards had to be reseated prior to them resuming operation.
2L26 unfortunately went to 0% level (outlet temp rose to 25K before beginning to cool again).
COMMENT ON Startup of Two Additional Central Chilled Water System Chillers and Associated Primary and Secondary Pumps and Final Commissioning
Chiller 60-CH-4 was successfully started today. Refrigerant charge may need to be adjusted a little when flow testing and balancing (TAB) is completed the chiller is more heavily loaded (system maximum load must only 47 percent of Chiller 60-CH-4 capacity). It was determined that a control board in Chiller 60-CH-3 was the low voltage signal issue source. The board will be replaced Monday. TAB and startup of Chiller 60-CH-3 should occur Monday 12/1/25. Chiller plant control sequence checks will occur after Chiller 60-CH-3 startup is successfully completed.
