Diagnostic cable to the compressor was knocked loose. Cable is re-attached and alarm is gone. System is fully operational, and users are able to scan. Will continue to monitor throughout the week for any additional leaks or problems.

Update
Per Siemens engineer: "It is OK to continue scanning, the system is at 50.4% helium and has been steady since ramping yesterday. Temperatures and pressure all look good, except the cold head compressor is not reporting correctly, which is most likely what triggered the alarm. Will be over to assess shortly."
