M25H Road Sweeper Operating Instructions
DPF regeneration (Stage V engines only)
During use of the sweeper the DPF ash/soot warning symbol may appear on the Main screen. This indicates that a standstill DPF regeneration is required.
DPF regeneration is the process of burning off (oxidizing) the accumulated soot from the diesel particle filter (DPF).
The regeneration process cannot be forced via the main screen. It can only be released if the Deutz ECU is
requesting regeneration due to ash/soot load or 550 engine hours have passed since the last regeneration.
The Serdia (Deutz) tool can be used to force a regeneration if desired.
Ensure that the vehicle is parked somewhere safe, away from the public, with plenty of ventilation.
DPF regeneration prerequisites
• Engine coolant temperature must be above 75°C
• Engine must be at idle
• The ECU must be requesting a standstill regeneration or is being forced by the service tool
• Enough fuel for at least 30 minutes run time.
DPF regeneration process
The operator must authorise the regeneration process by pressing the release button on the Scarab control system
display. Not the truck dashboard which may have its own button for the truck engine with a similar symbol.
This can be done via any of the screens shown to the right.
Press button
o
from the Main screen or press button
e
from either the After-treatment screen or the
EOL Test/Regen screen.
The regeneration process takes about 20 minutes but could be shorter or longer depending on condition of the DPF.
Button
w
from the After-treatment screen or EOL/Test Regen screen will cancel the Regen process.
For more information on how to access these screens see the section “LCD Monitor Screen” starting on page 56.
Whilst the regeneration is active the sweeper functions are disabled, this is to allow the system to control the engine
speed at a known load to carry out the regeneration efficiently.
Regeneration process completion
When the regeneration process has completed the following will happen depending on what screen you are viewing.
• The warning symbol will disappear from Main screen.
• On the After-treatment screen the Regen Status will show “Not Active”.
• On the EOL Test screen the Regen Flag will show “Regen finished successfully”.
Normal use of the sweeper is now available.
