DPF Indicator On Solid None None The indicator provides a
general indication of the
soot load. The indicator is
off when the soot load is
normal.
A regeneration is required.
In automatic mode the
ECM will decide when to
allow the active
regeneration.
If the DPF indicator stays
illuminated allow a manual
regeneration without inter-
ruption. An uninterrupted
active regeneration will re-
set the DPF indicator.
-
DPF Indicator On Solid Amber indicator Flashing The indicator indicates that
the soot load has
increased.
The engine will derate.
A manual regeneration is
required. Perform a man-
ual regeneration, or a serv-
ice regeneration will be
required.
-
DPF Indicator On Solid Amber indicator Flashing The flashing warning indi-
cator and red stop indicator
indicates that the engine
has continued to be oper-
ated while a regeneration
is required.
The engine will be derated
and the engine should be
shut down immediately.
Once the engine enters
into shutdown mode,
you must contact your
Perkins distributor or
your Perkins dealer.
Your dealer or distributor
will need to perform a serv-
ice level regeneration. The
DFP may need to be
replaced.

as a diagnostic lamp. For more information refer to
this Operation and Maintenance Manual, “Diagnostic

Regeneration Operation
Regeneration will require the following conditions:
Automatic Regeneration
In order for an automatic regeneration to take place
the engine must be at operating temperature.
Turning the keyswitch to the OFF position during a
regeneration will stop the regeneration. An interrupted
regeneration will not remove the soot from the DPF
and will waste fuel.
Wall Flow DPF Only
The engine Revs Per Minute (RPM) must be above
1200 RPM for the regeneration to start. Normal
operation can continue. During an automatic
regeneration the minimum idle speed will be
controlled to 950 RPM.
Manual Regeneration
The DPF indicator must be illuminated. Where
applicable, safety interlock for your application must
be engaged before a manual regeneration can occur,
refer to your OEM for more information. No throttle
inputs are required, the ECM will control the engine
RPM. Press the force regeneration switch for 2
seconds. Do not operate the application during the
manual regeneration.
