Hello,

pls give me some guidance of what are all the DLN's mode and what does it mean, like premix, extended lean lean,secondary xfer mode? Pls suggest me

 

It's kind of difficult to explain on this forum without drawings etc. If you send me an Email to [email protected] I can send you explanatory documents

 

Typically your Control Spec will have some pretty good information in it. I would check to see if you could get a copy and read through it, it should be pretty informative.
