If an active regeneration does not occur between 90%-
130% the DPF warning lamp will illuminate at 130%
(Figure 64 Point C). This may occur due to conditions
for active regeneration not being met or if the operator
has disabled the active regeneration. The DPF lamp is
used to indicate that regeneration of the DPF is
required. It is recommended that if applicable the DPF
regeneration disable switch be deactivated. If the
system has not been disabled then a manual
regeneration should be performed using the switch on
the control panel (Figure 62). If the DPF lamp is on for
one of the above reasons, then it will remain on until
regeneration has been completed.

If the DPF Regeneration disable switch continues to be
activated or a manual regeneration has not been
performed then the soot load will continue to increase
to 170% (Figure 64 Point D) at this point the warning
lamp will illuminate and the DPF lamp will remain
illuminated. The engine control system will invoke a
25% derate. At this point automatic regeneration is
disabled by the engine ECM, only a manual
regeneration can be completed.

tate 4 (E) – DPF Non Recoverable
If soot is allowed to accumulate to 230% the engine
should be stopped, the shutdown lamp will illuminate.
If the engine monitoring system is configured to
shutdown the engine will shutdown automatically. The
engine may be restarted but will shutdown after 30
seconds of operation.

ss
ure Monitoring (Wall Flow
Only)
The pressure differential measured across the DPF is
used as an input to a flow resistance model. This model
allows a comparison of the DPF soot load against the
primary soot load estimation model. Under normal
operating conditions the delta pressure based model
will predict soot load below the engine software model.
Active regeneration can be triggered from the flow
resistance model if the DPF is becoming blocked at a
higher rate than expected (according to the soot load
estimation model) (Figure 64 Point F).
