The Automated Radioxenon Analyzer/Sampler (ARSA) is a complex gas-collection and analysis system that requires constant online monitoring of system operations and overall system health. The software-control system records and monitors and over 100 different system sensors (temperature, pressures, voltages, etc.) A real-time record of the system state allows the system to monitor for unsafe conditions and maintain the system in a safe state regardless of external or internal failures (vacuum pump, valve or power failures, and runaway temperatures are a few examples). Another function of real-time monitoring allows the user to troubleshoot the system when a problem arises, should a minor sensor or a major system failure occur. This paper will outline the general scheme used by the state-of-health program to monitor and assess the system, the graphical user interface program and the alert message system, and give specific examples of proper system performance and some system failures.
