(Table 6, contd)
Amber Warning Lamp Lamp is now
flashing
The flashing lamp will indicate that the engine
has continued to be operated, regeneration is
required.
An urgent regeneration is required. If a regener-
ation is not allowed, the DPF could be damage.
Once the engine entres into shutdown mode
you must contact your Perkins dealer or your
Perkins distributor. Your dealer or distributor
will need to perform a service level regeneration.
The DFP may need to be replaced.
Red Stop Lamp On The engine could be derated or the engine could
be shut down.
Some applications will be equipped with a monitoring
gauge. Illustration 40 is an example of the levels of
soot loading on a gauge.
Illustration 40 g02153650
(1) Normal operation level 1
(2) Level 2 with DPF lamp illuminated
(3) level 3 with DPF lamp illuminated and amber warning lamp
illuminated.
During the normal working cycle of the engine the
ECM will control when the regeneration will occur.
Regeneration will take place by low speed automatic
regeneration or by enhanced automatic regeneration.
Operation of the engine at level 3 and not allowing a
regeneration to be performed could damage the DFP.
Soot Level and Engine Loading
Illustration 41 is a guide to show engine RPM engine
load and when regeneration can occur.
Illustration 41 g02237313
(A) Engine load factor
(B) Engine RPM
(1) Low speed automatic regeneration
(2) High speed automatic regeneration (60-80% soot load)
(3) High speed automatic regeneration (80-100% soot load)
In some circumstances high speed regeneration
cannot occur. Allow the application to operate at a
lower load factor in order to allow low speed
regeneration to occur.

Fuel Conservation Practices
The efficiency of the engine can affect the fuel
economy. Perkins design and technology in
manufacturing provides maximum fuel efficiency in
all applications. Follow the recommended procedures
to attain optimum performance for the life of the
engine.
• Avoid spilling fuel.
Fuel expands when it is warmed up. The fuel may
overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
