Once the amount of soot or sulfur collected has
reached, a critical threshold level the DPF indicator
and red STOP lamp will illuminate solid.
Regenerations may be locked out and require an
authorized Perkins distributor to perform
regeneration with service tool.
A fault code will be active for any DPF system-related
issue. Follow the troubleshooting guide to rectify the
issue.
If the DPF loses function, or is tampered with in any
way, the check engine lamp, and an amber action (if
equipped) will illuminate. A fault code will also
annunciate. The lamps and fault code will remain
active until the problem is rectified.
NOTICE
The engine and emissions control system shall be
operated, used, and maintained in accordance with
the instructions provided. Failure to follow the instruc-
tions could result in emissions performance that does
not meet the requirements applicable to the category
of the engine. No deliberate tampering with, or mis-
use of the engine emissions control system should
take place. Prompt action is critical to rectify any in-
correct operation, use, or maintenance of the emis-
sions control system.
Carbon Dioxide (CO
2
) Emissions
Statement
Emissions regulations require that the value of the
CO
2
emissions be reported to the end user. For this
engine, 717 g/kWh was determined to be the CO
2
value during the EU type approval process. This
value was recorded in EU type approval certificate.
This CO
2
measurement results from testing over a
fixed test cycle, under laboratory conditions, with a
parent engine representative of the engine family.
This value shall not imply or express any guarantee
of the performance of a particular engine.

Selective
Catalytic
Reduction
Warning
System
The
selective
catalytic
reduction
(SCR)
system
is
a
system
used
to
reduce
NOx
emissions
from
the
engine.
Diesel
exhaust
fluid
(DEF)
is
pumped
from
the
DEF
tank
and
is
sprayed
into
the
exhaust
stream.
The
DEF
reacts
with
the
SCR
catalyst
to
reduce
NOx
and
leaves
a
nitrogen
and
water
vapor.
The
Exhaust
Gas
Recirculation
(EGR)
system
cools,
measures,
and
introduces
recalculated
exhaust
gas
into
the
intake
manifold
to
aid
in
NOx
reduction.
The
engine
and
emissions
control
system
shall
be
operated,
used,
and
maintained
in
accordance
with
the
instructions
provided
to
the
end
user
to
maintain
the
emissions
performance
of
the
engine
within
the
requirements
applicable
to
the
category
of
the
engine.
No
deliberate
tampering
with,
or
misuse
of
the
engine
emissions
control
system
should
take
place.
In
particular
regarding
deactivating,
or
not
maintaining
the
SCR
system.
