8.1 Fail-Safe Operation

In cooperation with I/O modules and the ThermoView software, the camera provides a fail-safe system. That
system is designed to alert the operator and provide a safe output in case of any system failure. Basically, it is
designed to shut down the process in the event of a set-up error, system error, or a failure in the sensor electronics.
