Groundsmaster 4000--D/4010--D Page 3 -- 9 Yanmar Diesel Engine
Stationary regeneration is requested by the engine
ECU if the assist and reset regenerations do not return
the DPF particulate level to an acceptable level. During
the stationary regeneration, the engine ECU controls
engine speed, load and air/fuel mixture to perform a
controlled burn of the particulate collected in the DPF.
This type of regeneration is not a normal condition and
may indicate that t he DPF will require service soon, that
an engine problem exists (e.g. incorrect engine fuel or
oil) or that a DPF pressure sensor is failing. If a station-
ary regeneration is necessary, an advisory will occur on
the InfoCenter and the necessary steps will be listed. A
large icon will be displayed on the InfoCenter instead of
the temperature gauge during stationary regeneration
(Fig. 5). During the stationary regeneration process, the
InfoCenter display will identify the percent completed
during the process. The machine cannotbe used during
a stationary regeneration.
When the regeneration process is completed, the In-
foCenter will remove the stationary regeneration icon
andcease periodic regenerationmessages.The engine
will return to low idle speed with operator controls re-
turned to normal.
IMPORTANT: A stationary regeneration should
ONLY be initiated if an InfoCenter display advisory
requests that t his be done.
IMPORTANT: During a stationary regeneration,
make sure that the machine is parked on a hard,
level surface in a well ventilated area. This process
runs the machine at a high er exhaust temperature
for a period of approximately thirty (30) minutes to
burn off collected particulate in the DPF.
