The Advanced Scan Fail Safety of the Xscan scanners can be switched to three different modes:
The Fail Safety mode permanently checks if the scanner output matches the input signal. If there is any deviation, it switches of the laser output.
The Beam Block Safety mode completely blocks every focussed beam (threshold can be adjusted) and also has the Fail Safety functions enabled.
As third option it is also possible to completely deactivate the scanner safety (not recommended, for testing or scientific use only).
The manual for the Xscan scanner s shows how the settings can be adjusted.
The setting for the Advanced Scan Fail Safety for upgraded systems with CT-6210HP works similar.
