Detroit 14L 60 Series Regen issues

Looks like 345 degrees at outlet temp. Think you may be looking at min and Max columns.

 

I guess my screen shot won't open that wide, I see nothing at the top. Not sure why any value would post other than the one that matters but I'm good with this also, so we got temp on all VBOC-(Vertical Back Of Cab) temperature sensors, now we need to generate enough heat for the ACM to to command the intake module to open and supply fuel to the fuel doser to really pour on the coals, this is where the diverting valve on the compressor side of the turbo (with the air line I mentioned earlier), that runs to a block mounted (purge/air) solenoid, will open to supply an oxygen rich air supply via the fuel doser "T" fitting to the DOC to bring the temps up to about 700+/800+ (I forgot), once this target temperature is reached the intake module will open and supply fuel to the doser and will take you into the 1000+ degree point. It's been awhile for me on a gen 1 and I probably didn't detail it quite right but a soot blocked DOC will not react to an oxygen rich atmosphere or a diesel rich atmosphere, and a successful "purge" test only means that the solenoid opened and closed as commanded, not that it actually delivered the air (bad line). I have a detailed manufactures manual that precisely describes these subsystems regardless how badly I butchered the description, sorry hope this helps a bit, thanks.

 

Haven't ever worked on a Series 60 with a DPF, but never seen any other engine open EGR valve during regen. EGR lowers cylinder temp, you are wanting to raise them. Thinking Series 60 uses intake throttle valve to help increase temps for stationary regen. Might want to verify its operation and make sure have no boost leaks, low fuel pressure, or weak injectors. I have kicked manual fan on in cold weather before to get a truck start a regen.
