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.
