Form No. 3420-558 Rev A Diesel Particulate Filter Operation Guide Machines with Yanmar Tier 4-F Engines Software Guide Introduction Operation This Software Guide describes operation of the machine software that controls the diesel particulate filter regenerations for the machines with the 3-button InfoCenter. Diesel Particulate Filter Regeneration The diesel particulate filter (DPF) is part of the exhaust system.
PAGE 2
DPF Soot Accumulation • DPF regeneration is a process that heats the DPF to convert the soot to ash. • Over time, the diesel particulate filter accumulates • In addition to the warning messages, the computer soot in the soot filter. The computer for the engine monitors the soot level in the DPF. reduces the power produced by the engine at different soot-accumulation levels. • When enough soot accumulates, the computer informs you that it is time to regenerate the DPF.
PAGE 3
DPF Ash Accumulation • When enough ash accumulates, the engine • The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter. • Ash is a residue of the regeneration process. Over • time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust. • • The computer for the engine calculates the amount of ash accumulated in the DPF.
PAGE 4
Types of Diesel Particulate Filter Regeneration Types of diesel particulate filter regeneration that are performed while the machine is operating: Type of Regeneration Conditions that cause DPF regeneration DPF description of operation Passive Occurs during normal operation of the machine at high-engine speed or high-engine load • The InfoCenter does not display an icon indicating passive regeneration.
PAGE 5
Types of diesel particulate filter regeneration that require you to park the machine: (cont'd.) Type of Regeneration Conditions that cause DPF regeneration DPF description of operation Recovery Occurs because the operator ignored requests for a parked regeneration and continued operating the machine, adding more soot to the DPF • When the reset-standby/parked or recovery regeneration icon or ADVISORY #190 displays in the InfoCenter, a recovery regeneration is requested.
PAGE 6
Technician Menu DPF Operation Table Important: For operating convenience, you may decide to perform a parked regeneration before the soot load reaches 100%, provided the engine has run more than 50 hours since the last successful reset, parked, or recovery regeneration. Use the technician menu to view the current state of engine regeneration control and view the reported soot level. State Description Normal The DPF is in normal-operating mode—passive regeneration.
PAGE 7
Passive DPF Regeneration Important: The high exhaust-temperature icon indicates that the exhaust temperature discharged from of your machine may be hotter than during regular operation. • Passive regeneration occurs as part of normal engine operation. • While operating the machine, run the engine at • While operating the machine, run the engine at full-engine speed and high load when possible to promote DPF regeneration. full engine speed and high load when possible to promote DPF regeneration.

g227304 g224394 Figure 13 2. Figure 15 Press the right button to change the inhibit regeneration setting from On to Off (Figure 13) or from Off to On (Figure 14). Note: If the engine exhaust temperature is too low, the InfoCenter displays ADVISORY #186 (Figure 16) to inform you to set the engine to full throttle (high idle).
PAGE 9
Parked or Recovery Regeneration regeneration required—power takeoff disabled ADVISORY #189 (Figure 20). • When the engine computer requests either a parked regeneration or a recovery regeneration, the regeneration request icon (Figure 17) displays in the InfoCenter. g224398 Figure 20 Important: Perform a parked regeneration to restore the PTO function; refer to Preparing to Perform a Parked or Recovery Regeneration (page 10) and Performing a Parked or Recovery Regeneration (page 10).

Important: Perform a recovery regeneration 2. to restore the PTO function; refer to Preparing to Perform a Parked or Recovery Regeneration (page 10) and Performing a Parked or Recovery Regeneration (page 10). Move the machine outside to an area away from combustible materials. 3. Park the machine on a level surface. 4. Ensure that the traction control or motion-control levers are in the NEUTRAL position. 5. If applicable, shut off the PTO, and lower the cutting units or accessories. 6.

3. At the DPF checklist screen, verify that the parking brake is engaged and that the engine speed is set to low idle (Figure 28). g224402 g224407 g224629 Figure 26 2. At the VERIFY FUEL LEVEL screen, verify that you have 1/4 tank of fuel if you are performing the parked regeneration or 1/2 tank of fuel if you are performing the recovery regeneration, and press the right button to continue (Figure 27). g227679 Figure 28 4.

5. The InfoCenter displays the INITIATING DPF REGEN message (Figure 30). Check Message and Corrective Action Table (cont'd.) g224411 Corrective Action: Start and run the engine. g227681 Figure 30 6. Corrective Action: Run the engine to warm the coolant temperature to 60°C (140°F). The InfoCenter displays the time to complete message (Figure 31). Corrective Action: Change the engine speed to low idle. g224406 Corrective Action: Troubleshoot the engine computer condition and retry DPF regeneration.

Canceling a Parked or Recovery Regeneration displays ADVISORY #183 (Figure 33). Press the left button to exit to the home screen. Use the Parked Regen Cancel or Recovery Regen Cancel setting to cancel a running parked or recovery regeneration process. 1. Access the DPF Regeneration menu (Figure 35). g224392 Figure 33 g227305 Note: If the regeneration fails to complete, the Figure 35 InfoCenter displays Advisory #184 (Figure 33). Press the left button to exit to the home screen. 2.
