So, after almost a decade of flawless performance, our Sensor 24 Pack is giving me grief. A particular address is not able to produce a steady output. When I bring up the address on the board (or at the rack), the light attached flashes sometimes rhythmically, sometimes sporadically. I've noticed that even the signal LED on the dimmer module flashes at the same time as if the signal going to the module is being interrupted. I've swapped modules around and the problem seems to stay in the position leading me to think it's a MPE module problem, but I don't really have an idea what I could be looking for or if this has to be a service call. Any thoughts?
