I have a client that has several WAC cable track systems with magnetic drivers. Some are 3-wire tracks with a shared common. These work fine. There are several 2-wire tracks in the stair and these work fine.
The gallery has 2 independent sections of track controlled by 2 identical WAC MLV transformers(I think they are 600w) and 2 RRD-6NA. One of the 6NAs randomly goes into protect mode. The dimmer is remotely located so the owner has to go upstairs and reset it. It may then work for some random number of cycles. The other 6NA never has an issue. I tried swapping the dimmer with the dining chandelier and the issue stayed with the track. I have tried using forward and reverse phase with a variety of high and low end trim settings with no luck.
The other distinction is the track that goes into protect mode has 3 MR16 LED fixtures. The track with no issue has 6 (maybe more) MR16 LED fixtures. I'm wondering if there is a minimum load issue with the transformer itself. WAC is, of course, no help. I'm thinking about installing a MLC on the transformer itself or maybe even adding a fixture or two to the short track.
Any thoughts?
