I'm hoping someone might be able to chime in if they have seen something similar before.
I'm driving two contactors (they close at different times) off the MC41. The contactors at peak draw 3.9A for about 75ms. When the contactors close, a very short time later, the MC41 enters a critical fault. The flashing lights (4R, 1Y, 12Y, 3Y, 1Y, 2Y) seems to indicate there is a 'watchdog' fault. Looking at my CPU/RAM usage and cycle usage, we are not even using 1% capacity. Is it possible this overcurrent condition could trigger this particular fault?
As well, I can't seem to find any information on what the 12Y is supposed to mean? "R4:1 n:3:1:2" which would be the "n" in the manual. What would the 12th part of the software mean?
