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.
