Passive regens how often.

[Shipit]

I haul short and heavy. Sometimes idle more than drive. Hauling grain you sit in a line of 30 trucks pulling forward every 10 min then run 20 miles and do it again. My cm2350 is doing them every time I restart or use the jake. I'm sure it's full of carbon. It seems if I leave truck running it doesn't do as many ? On time it was doing it during extremely dusty conditions. Which grain dust is explosive. The inhibit switch don't seem to prevent it from doing it. Is four or five time a day excessive for this type of work.?
