Types of DPF regeneration that require you to park the machine:
Type of Regeneration
Parked
Conditions that cause DPF regeneration
Occurs during normal operation of the machine at
high-engine speed or high-engine load
Occurs because of low-engine speed, low-engine
load, or after the computer detects the DPF is
becoming obstructed with soot
Occurs every 100 hours
Also occurs after assist regeneration only if the
computer detects that assist regeneration did not
sufficiently reduce the soot level
Conditions that cause DPF regeneration
Occurs because the computer detects back
pressure in the DPF due to soot buildup
Also occurs because the operator initiates a parked
regeneration
May occur because you set the InfoCenter to inhibit
reset regeneration and continued operating the
machine, adding more soot when the DPF already
needs a reset regeneration
May result from using the incorrect fuel or engine oil
DPF description of operation
•
The InfoCenter does not display an icon
indicating passive regeneration.
•
During passive regeneration, the DPF
processes high-heat exhaust gasses, oxidizing
harmful emissions, and burning soot to ash.

The InfoCenter does not display an icon
indicating assist regeneration.
