This was my first experience of fitting a Tridonic digital dimmable ballast. I thought: "how hard can it be ... ".
There are four ballasts per fitting, two lamps per ballast. A number of fittings on a single switch.
I laid the new ballast alongside failed one, and swapped the wires one for one to make sure I didn't get any mixed up. New ballast has identical labeling for wires as old one.
When I turned power back on I found the new ballast was dimming its lamps UP, while the rest of the fittings were dimming their lamps DOWN! :-( And vice versa.
I tried suppliers customer services and Tridonic website for installation information, but this appears limited for this model - a PCA Excel one4all.
However, under section titled 'switchDIM' I 've found mention on 'synchronisation' using different durations of switch push - this seems to refer to a toggle type switch, allowing switch to be 'pulsed' briefly or held down for several seconds to reset factory settings.
Has anyone any experience of this problem, and whether solving it is simply a matter of synchronisation using switch pushes please?
