DPF REGENERATION (REGEN)
Before operating the paver, it is important that the
operator understand the Diesel Particulate Filter
(DPF) regeneration process described throughout the
following pages. DPF regeneration is the term given to
the cleaning process where the exhaust temperature
is raised to safely burn off any soot and undesired
combustion gas. When the DPF lter reaches a soot
saturation level between 25 - 45 percent, the onboard
engine ECU (Engine Control Unit) will activate a
regeneration cycle. The DPF icon on the DM430 digital
controller indicates the level of soot build-up on a scale
of Level 0 - 5. Regeneration will occur automatically
at Level 1 - 2. DPF is further explained on the following
pages.
During normal operation, the DPF is cleaned
automatically. Under certain conditions, the operator
may have to instruct the control system to perform the
cleaning process. It is important to perform a parked,
manual regeneration BEFORE the engine reaches
as high as Level 4. If the DPF reaches Level 4 - 5,
non-warranty factory assistance from the engine
manufacturer is required.
Once the regeneration cycle has been activated, it is
important not to shut off the engine as the regeneration
cycle will fail and could possibly damage the engine.
The system may attempt a second regeneration, but if it
is unsuccessful, the DPF lter is blocked more than 80
percent and needs to be cleaned or replaced.
The engine speed will increase during regeneration
and there may be a noticeable sound difference. Once
regeneration is complete, the engine will return to
normal idle speed.
Don’t idle machine any longer than
necessary as too much idling can cause soot to build
up on the DPF, requiring more frequent regeneration.
There are several factors that affect how often your DPF
regenerates and the life expectancy of your DPF lter:
• Grade of engine oil.
• Grade of diesel fuel.
• Use of additives.
• Mileage.
• Wear of other components.
DM430 DIGITAL DISPLAY
The DM430 digital display features a high-resolution,
anti-glare color display screen optimized with wide
viewing angles in a variety of lighting conditions. When
starting the engine, the “boot” screen automatically
displays on the DM430 digital display unit, followed by
the Engine screen.
Keep the controller screen clean
by wiping with a soft, damp cloth. Use a mild dish
washing detergent if needed. To avoid scratching or
discoloring the display, DO NOT use abrasive pads,
scouring powders or solvents (such as alcohol,
benzene or paint thinner).
Pressing “soft key” buttons on the control unit navigates
to other screens, scrolls through information, toggles
between screens and allows users to make selections
as described on the following pages. A banner along
the bottom of some screens correspond with the
four function selection buttons (), and may change
accordingly as described on the following pages.
Symbols and pop-up alert messages may
also appear on the engine (and pave)
screens as described throughout this
section. (Table 4-2 beginning on Page 4-16)
