vtfireman85 Posted August 13 Share Posted August 13 While running the backhoe today it beeped and showed an exhaust filter symbol and “on” underneath, I continued running it at 1500 as I had been because I suspected it shouldn’t be shut down, it beeped snd flashed the symbol a couple more times over 10-15 minutes, then it showed the symbol and “off” and didn’t do it again all day. Did it do a burn cycle and its all good now? What should I have done differently? Any information would be great. Quote Link to comment Share on other sites More sharing options...

searcyfarms Posted August 13 Share Posted August 13 likely so, my deere Compact Tractor = light comes on, you have to keep running it, it wont even shut off IIRC i think i tried that once, if you try to lower the idle it will not lower below a certain point it runs the idle up to do what it needs to do, it takes mine around 30 mins when it comes on while I am cutting the grass to go back down to 0% Quote Link to comment Share on other sites More sharing options...
Lars (midessa) Posted August 13 Share Posted August 13 Although I am not familiar with DPF systems on construction equipment, generally a symbol like the one you showed indicates exhaust temps are high. Is there an operators manual? Or decals on a nearby sun visor, or sidewall? Quote Link to comment Share on other sites More sharing options...

Turn the key off, remove the key, it will still run until the burnout is done. And burn nearly a half a tank of fuel to do it.... Quote Link to comment Share on other sites More sharing options...
cm228 Posted August 13 Share Posted August 13 As others mentioned. That’s normal operation. The symbol you showed is to tell you the exhaust is very hot so you avoid combustable materials while the regen is running Matt 1 Quote Link to comment Share on other sites More sharing options...
poor farmer/logger Posted August 13 Share Posted August 13 Yup. Sounds normal. You did the right thing revving the motor up. They need heat to burn out properly. I keep after dad not to idle the skid steer around while it’s doing it’s thing. So far hasn't caused any issues but im sure the day is coming.

1566Hog Posted August 13 Share Posted August 13 On my CAT 329E hoe, it shows a percentage of how full the DPF is before I need to do a manual burn. When I first got it, I thought it would do it automatically as I was operating the controls. Well, I needed to keep digging a pipeline in, as there was 5 guys waiting around on me. So I kept going. DPF percentage got to 115% and then derated me. I couldn’t even do a manual burn to it as the CAT service tech talked like I should. Found out, once you hit 115%, CAT has to come out and hookup their computer to do the burn and reset it. Expensive mistake I guess you could put it. So I always burn it manually when I see it getting to about 70%. I realize not every machine is set up this way, and may not even show you the percentage. I guess I’m giving out free advice to anyone who sees the light on for awhile to just make a quick phone call to their service guy before you wait too long and need a on-site service call like I did. 2 Quote Link to comment Share on other sites More sharing options...

Friends have a NH excavator that they plugged the DPF in, it was similarly inconvenient and very expensive, I almost think it needed to be replaced.

MTB98 Posted August 13 Share Posted August 13 5 hours ago, vtfireman85 said: It is a PDF ( short for PITA) 20 miles away on a computer. Storing PDFs of frequently used operators manuals (vehicle, tractor, attachments, etc) doesn’t take up much room on a smartphone and then they’re always handy. New things are getting complicated and have so many features it’s good to have a book to look up how they work or what different warning lights may mean. 7 minutes ago, Diesel Doctor said: Why do they use indistinguishable symbols? What is wrong with English? After awhile the DPF symbol will be common enough that everyone will know what it means. An oil pressure symbol or seat belt light or battery light makes sense to all of us because we’ve seen them for years and years. Quote Link to comment Share on other sites More sharing options...

Cattech Posted August 13 Share Posted August 13 Bit of advice for everyone running emissions compliant diesels.... Talk to the service department at the dealer, educate yourself on what indicators mean what...! Most of the time, the emissions equipment is made to run in the background and you don't have to worry about it. But a lot of the time, it requires the machine being operated in a certain way. An example, there's probably quite a few people here who run Cat D series skidloaders, but few who know this about them... The throttle dial has a green zone from about 50% up. If you always run the machine with the throttle in that green zone, it will regen on its own during normal operation. If you run it below that, it will need a parked regen from time to time. I would say 1/3 of the emissions related problems we repair are operator induced. People spend thousands of dollars repairing things that would have been fine had they simply paid attention to the light on the dash and known what it meant. 1 1 Quote Link to comment Share on other sites More sharing options...

iowaboy1965 Posted August 13 Share Posted August 13 I'm so old I can recall when an oil light actually said OIL!!! These new universal symbols aren't really. 🙄 I would have no idea what the symbol above meant if I saw it. Quote Link to comment Share on other sites More sharing options...

Even a basic passenger car has dozens of warning lamps now. There are websites for dashboard warning lights, quite a few symbols to memorize. https://dashboardsymbols.com/2011/08/diesel-particulate-filter-dpf-warning-symbol-indicators/ Quote Link to comment Share on other sites More sharing options...

Just means we can be confused world wide by vague symbols that are not self explanatory most times. Another reason I am not a fan of glo bull anything.

If I ever catch the software engineer that wrote the programing for those machines I will probably do jail time after that meeting . . . That and they used crap potentiometers for the controls . . .

Cat isn't what it used to be. Our county as been running Cat graders forever but last several have been problematic to the point one was traded for a JD a couple years ago. Also have one Case grader.
