Machine trip just as I was exiting the TRIUMF gate. QRL said cold box fault 
as did red lite on compressor. At cold box panel all turbine red lites were 
on and compressed air failure lite was on. But there was no problems with 
compressed air. On fist trip logger LED # 8 and 16 were lit. Restarted 
compressor then start flow to cold box, start turbines, start // warm 
return until temps returning back from solenoid were <= TIC121 then 
switched to //cold return mode. Opened cv155 to 0.88
Solenoid temps at 24K and starting to trend down.
