ACCC configuration defines cylinder cutout for cold
cranking and cold running conditions. This
configuration electronically disables cylinder(s),
which improves fuel efficiency by controlling the fuel
delivery to the injectors. This action does not
compromise engine power output.
Alternative Engine Starting
Procedure
Note: For a new engine, or when a long block has
been obtained and rebuilt in service, or after a major
overall, Perkins recommends following the procedure
below:
Note: When possible, ensure that the engine is not
started under load.
1. After completion of the installation process, prime
the fuel system and the lubricating oil system.
Refer to Operation and Maintenance Manual for
more information.
2. Apply power to the ECM. Ensure keyswitch is
enabled. With the RUN / STOP switch set to the
STOP position, crank the engine for 15 seconds.
Do not start the engine.
3. With the RUN / STOP switch set to the RUN
position, crank the engine. The engine should start
and operate at the rated speed, operate the
engine for 1 minute. The oil pressure will be
monitored by the ECM. If the engine oil pressure
does not reach the required level, the ECM will log
a fault and the engine will stop automatically.
4. Stop the engine. Inspect the engine for leaks from
the fuel, coolant, and lubricating oil systems.
a. If no leaks are present, proceed to step 5.
b. If leaks are present, repair the leaks. Repeat
Step 3 to Step 4.
5. Start the engine. Operate the engine for 1 minute.
Monitor the engine oil pressure. Continue to
operate the engine with no load applied for 4
minutes. The total time period for this operation is
5 minutes.
Note: After the engine has run for 5 minutes, check
the engine monitoring systems. Ensure that the
engine is operating correctly before the load is
applied.
6. Increase the engine load to 50 percent of prime
power over a 60 second time period. Operate the
engine for 20 minutes at 50 percent engine load.
7. Increase the engine load to 100 percent of prime
power over a 90 second time period. Operate the
engine for 20 minutes at 100 percent engine load.
8. Gradually remove all the engine load over a 60
second time period.
9. Operate the engine off load for a time period of 4
minutes to reduce the operating temperature of
the engine.
10. Stop the engine. Inspect the engine for leaks from
the fuel, coolant, and lubricating oil systems.

Cold Weather Starting
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
Follow the recommendations that are detailed below
will improve cold starting and reduce white smoke
emissions.
Below 10 °C (50 °F) jacket water heater must be
installed and operating at temperature of 60 °C
(140 °F).
At temperatures of between 10 °C (50 °F) and
−18 °C (−0.4 °F), if equipped, a closed circuit
breather heater must be operated to prevent
freezing. At temperatures of below −18 °C (−0.4 °F),
refer to your Perkins distributor for more information.
No load operation and or multiple start/stop events in
colder ambient conditions can cause the emission of
white smoke from the exhaust. The emission of white
smoke from the exhaust is a result of partly unburnt
fuel due to the low cylinder temperatures. No load
operation should be avoided and multiple start/stop
events kept to a minimum.
Air filters to pull in air from inside the canopy or
enclosure, not outside the canopy or enclosure.
Fully charged batteries of the correct capacity.
Electrical cables that meet the recommended
specification.
Contact your Perkins distributor or Perkins dealer for
more information.
