Confused About Regen

[rjpotts]

While mowing with my 3510 (just reached 40 hours) I glanced down and saw a regen light. I told myself to just keep mowing and the regen process would run it's course. After a while the light went out and I continued mowing until all the grass was cut.

Afterwards I opened the manual to assure myself that I did the right thing, that's when I became confused. Looking back I think the regen light I saw was the "regen underway" light but now I'm not sure, I suppose it could have been the "regen warning" light, again I'm just not sure. I didn't realize there were 2 different regen lights until I saw it in the manual.

At no time did I push the "regen now" button, should I have?

Is there anyway after the fact that I confirm a regen actually occurred?

The regen happens automatically and the light will show. If you do not want the regen to happen, like if your are in an area with highly combustible material, or don't want high revs for some reason, then you can by-pass it and use the 'regen now' button to start the regen later.

edit:

Clarification: The light with the 'temperature' symbol means that the regen is underway. You dont have to do anything other than let it finish, meaning if you are done with the tractor before it goes out, leave it at high RPM until if finishes and dont just shut the tractor off.

The other light that looks like air blowing through a filter means that regen is required, but did not start or was canceled by the operator. In this case when you are done using the tractor, park it someplace safe, set the parking brake and manually start the regen.

It's pretty much recommended to do what you did and just keep working while it regens on it own. It does no harm and seems to finish faster this way anyways since the engine is under load and thus hotter. The exceptions would be as noted above.

You did the right thing.

These new tractors need just a few more lights, bells & whistles. If they wanted to make it user friendly - the light should have been followed by a short message - "pg XX in Op Manual". Come on - if the regen is fully automated - surely a short message wouldn't be that difficult.

You should have heard a slight change in the sound of the engine while it was doing the regen. It usually smells a bit too, although it may not at only 40hrs.

My 3510se did normal "in use" regens up until just shy of 400hrs. Then it started going into a near constant cycle of regens, every 2-3 hours it would try to do one. After 4 or 5 of these, the other regen light finally came on, for the first time, indicating it was time for a parked manual regen. Since then, I've put another 100ish hours on the machine, and it's just done a couple of the "in use" regens since.

The only time I've ever pushed the regen button, is when I got the light indicating a parked regen was needed.

Very helpful, Thanks!

Or maybe a "regen complete" message.

Thanks for that. I am ~35 hours on mine and figure I should be seeing something soon. I kind of understood it to be how you stated but wasn't quite sure, the language in the manual is not entirely clear and the legends for the lights are very similar. You've cleared it up for me, thanks!

Edit... just got my first regen today at 38 hours while mowing. Light came on, could hear a different "loading" on engine, different smell, seems like it was less than 10 minutes light went out. Just like 'Oyl' said.

Sold around the world and used by people who speak hundreds of languages. For many users those words wouldn’t mean anymore than the pictures.
Just read the manual. Very clear. And for all who preach “it’s the dealer!” It is astonishing how many dealers didn’t cover regen (mine did, and I don’t and didn’t give a flip about who my dealer was)

Operator Manual addresses Regen in this order:

First it calls out DPF Regeneration warning lamp
"If carbon is accumulated in the exhaust
catalytic filter, this warning
lamp comes on or blinks.
If this warning lamp comes on, press
the "regeneration" button."

Then it calls out DPF Regeneration underway lamp
"This lamp comes on while the regeneration
process is being performed in
the DPF."

Followed by:
1. Stage 1 warning lamp for DPF clogging: DPF Soot Loading Level 120% - 160%
Manual regeneration required Engine RP M limit (below 2,200rpm)
If this warning lamp comes on, make sure to press the "regeneration" button.
(see page 4-12)

2. Stage 2 warning lamp for DPF clogging: DPF Soot Loading Level 160% - 200%
Manual regeneration required Engine RPM limit (below 2,200rpm)
If the DPF is not regenerated in the stage 1 warning state, the warning lamp blinks.
In this state, make sure to perform DP F regeneration process.
(see page 4-12)

3. Stage 3 warning lamp for DPF clogging: DPF Soot Loading Level 200% or higher
P assive regeneration prohibited
E ngine RP M limit (below 1,500rpm)
If the DP F is still not regenerated even in this state,
the Check engine lamp comes on and the DPF needs to be replaced.

This doesn't include the info boxes alongside like
!!WARNING!!
In the warning level 3 (CEL lamp ON ), both manual and automatic regeneration processes cannot be performed.
When the DP F warning lamp comes on, make sure to perform the manual regeneration as the active regeneration cannot be performed.
Enabling condition for manual regeneration
- Clutch engaged
- Brake ON
- Engine rpm Idle state
If any of the above conditions is not met during regeneration, the regeneration mode is deactivated.

"Just read the manual. Very clear."
Not so much for someone that has never owned a Tier4 tractor.
