I have recently installed a new cbus system to a restaurant but am having issues where three different banks of lights on three separate universal dimmer modules have turned themselves off and then turned back on again a second or two later. I have not overloaded the current rating of the individual channels and the problem has arisen on two banks of down lights on electronic transformers and one bank of fittings that have an integral iron core transformer. One bank of lights had nine down lights (450W), another bank has eight down lights (400W) and the third has just four fittings (200W). Coincidently or possibly too coincidently all three banks of lights are the only three that were actually wired with two separate switch wires to each bank but doubled up in to one channel in the dimmer to save money (not my idea!), i.e three channels used instead of six. This is apparently a known occasional problem. Has anyone encountered this problem? Can you suggest a cause and a possible cure? Why if an iron core transformer is installed in a fitting is the cbus module showing an amber light? Shouldn't it be green? Any help would be greatly appreciated.
