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.
Warning
The Fail-Safe circuit should never be relied on exclusively to protect critical processes. Other
safety devices should also be used to supplement this function!
