DPF and RegenerationDPF and Regeneration
It cannot be emphasized enough that the paver
should be maintained in good operating condition so
the emission system can automatically perform the
regeneration (regen) process.
If engine faults are present that
prevent the ability to perform regeneration, DPF
levels will continue to rise. It is important to
resolve any engine faults immediately and perform
the needed regeneration to prevent costly DPF
technician service if DPF level warnings or engine
faults are ignored.
If regeneration begins while operating, immediately
move the paver to a safe location to allow regeneration
to occur. During regeneration, there may be a
noticeable sound difference. The high exhaust
temperature icon will illuminate on engine and pave
screens will appear during the process.
• If unable to move to a safe location for the engine to
perform a regeneration automatically, the operator
may choose to temporarily inhibit (disable) the
regeneration process.
• Press Button #4 while on the Engine screen,
then use Button #2 to inhibit regeneration,
described on Page 4-15, until you can move
to a safe location and complete the parked
regeneration process. (Pages 4-32 and 4-33)
NOTE: The ability to inhibit (disable) regeneration
is only possible at DPF levels 1 and 2,
described on the following page.
NOTE: Regeneration will remain disabled until the
engine is turned off or the operator navigates
back to the screen to enable regeneration.
EXHAUST TEMPERATURES WILL BE
EXTREMELY HIGH. BE SURE EXHAUST WILL NOT
COME INTO CONTACT WITH ANY COMBUSTIBLE
MATERIALS.
Monitor the surrounding area during
regeneration. If unsafe conditions develop, shut the
unit off immediately.
DPF LevelsDPF Levels
Pay attention to the DPF level
icon on the engine and pave
screens. Automatic regeneration
can only occur at DPF Level 1
and 2.
DO NOT allow soot levels to reach high levels to prevent
damage to the engine and/or DPF components that will
require costly repairs. DPF levels are described below.
NOTE: If the operator has not inhibited regeneration
and there are no engine faults, but automatic
regeneration is not occurring at DPF Level
1 or 2, increase engine RPMs and/or load to
allow the DPF to automatically regenerate.
It is important to perform a parked
regeneration BEFORE the DPF level reaches Level
4. If the regeneration process is not performed and
the soot level reaches Level 4, non-warranty factory
assistance from the engine manufacturer is required.
If an engine fault is present at DPF Levels 1 and 2, a
message banner may appear on the engine and pave
screen notifying operator regeneration is not possible
until the engine fault is resolved. DPF levels will continue
to rise. (Figure 4-35)
