I went back into family for Xmas and my father has some pb with his kiln controller (a Hartmann&Braun, now ABB, Protronic PS 2) he was given. His problems are probably basic prog/config but 2 hours playing with it and as much passed googling for a manual didn't lead to anything. (any hint?)
So I guess it's time to not waste more time and get a new controller.
What would the industrial wizards recommend? (pref. low cost available on ebay)
Requirements:
220V-50Hz mains
K type input or (0-20/4-20, he already has the converter)
0-1300°C at least 3 programmable ramp rates (2 up, 1 down) at least 2 plateau durations PID auto-tuning (I'll be 700km away)
Easy temperature profile programming (i.e. front panel) The output will drive a small relay... which will drive the power relay (10kW-3phases), so no real power requirement.
Manual available on line.
