Hi all I haven't posted for a few years, I used to post under the name Kelly but forgot my password details etc so I have re registered under Frantic. The issue I am having is with Universal dimmers and channels turning OFF and then turning back ON again. It is a new house that I commissioned mid 2011 and has 6 universal dimmers installed. It is dimming 50W dicroic lamps only. The Electrician that wired the job did a good job and wired the house to normal wiring practices. He ran out a circuit from the switchboard looping the Earth and Neutral conductors to each fitting including ceiling sweep fans on CBus fan control relays on the circuit and ran a single active back to the enclosure with the Universal Dimmers. The client has reported and I have seen it once myself that some of the lighting channels will turn themselves OFF and then back ON instantaneously. It is not always the same channel and they cannot pick a trigger that will make this fault happen. It usually happens at least once a day. I set up a log on the touchscreen and asked them to check it when it happened but the log doesn't pick it up. Its fair to say they are not happy. I have had my project checked by CIS and they could see no problems. The response I have had from Tech Support and they have been helpful is It has been suggested that their could be a common neutral on the loads that is causing the universal dimmers to think they need to change between trailing or leading edge. If the loads on the dimmers and relays etc share a common neutral between them, if say a couple of channels are active on a universal dimmer and then another channel on a relay is turned on, if sharing a common neutral there is a voltage change/difference detected by the other universal dimmer that may trick it into thinking that it needs to change it's state of leading or trailing which would result in the loads turning off then on. Has anyone experienced this issue and have you any suggestions in rectifying the fault.. Thanks Mark
