I recieved a call from ops at 22:00 tonight that the solenoid had alarmed. 
I came in and found a cold box fault, with the compressor tripped off. I 
was unable to restart the compressor. I cleared the cryostat quench and 
compressor trips. The system looked as though it was ready to start. I 
pushed the compressor "ON" button, but as soon as the main contactor 
closed, the compressor tripped again. After a few trys and a bit of 
searching, I tried resetting the compressor over-pressure switch. That 
allowed me to restart the compressor. Once the high pressure comes up I'll 
start flow to the turbines.

Came in this morning to find the helium return line to the buffer tank 
frosted up. MV51 has been stuck open the whole time. That exlains the 
cooldown rate and other problem. Cycled MV51 a few times and it now seems 
closed. Switched back to parallel cold return this moring at 8:00. Rates 
are much better. The E-log was also down this morning.

Power lead temps have been slowly increasing over the last wekk. I ramped 
the solenoid down and am warming the power leads to >80k.
