In our physics lab we are facing a problem with a T40 power supply from an old 5W Millennia Vs laser. This system is already more than 10 years old, and it is no more supported by Spectra-Physics (at least in our region). Nevertheless this system worked well for all these years, and we only had to make some minor maintenance, and once to replace the burned high-current power supply.
Recently we experienced a problem: during the start-up power supply showed an error 201 ("Diode 1 current calibration required"), and after a while error 205 ("Diode 1 temperature calibration required"). We have never experienced this errors with this laser before. Millennia user manual says nothing about these error codes too.
We would appreciate it if somebody could give us advice about what could be a problem here? Thanks!
