I was phoned at about 9:30 tonight with a solenoid alarm. After looking at 
the display I found the system to be tripped off. When I came in I found 
the compressor off and the solenoid quenched. There was no real indication 
of the problem other than a cold box fault. I restarted the compressor and 
started flow to the cold box.
