Hello All
I just installed two R20 modules, one in each of two 72 channel sensor plus portable racks. The relays were fine for the first few hours but they have begun "flickering," rapidly switching on and off. About 30 times per second. Its not consistent, it happens every few minutes for a fews seconds. Sometimes more then others. It appears to happen less when the DMX value sent to them is 90%. There is no change in the behavior when I remove the DMX feed to the racks. It is LED pars and LED moving heads on the circuits. They are not overloaded. I have installed this type of fixture on R20s before with no problem. I swapped out the modules and got the same behavior. The racks are pretty caked in dust. Thoughts?
