Just took delivery of a few Velbus bits to play with and have a go at programming in Visual Studio 2008, thats giving me issues… but first and more importantly…
I have got an issue with the power supply VMB3PS, it is powered from a Velbus transformer VMBTR1, however when connected up as described in the manual as a single output transformer… positive in to terminal A and negative into terminal F and terminals B and C bridged and then D and E bridged…
I get +20 volts at the output !
I get the right lights on, but do they just show power, or correct voltage and polarity ?
What am i missing ?
