2. Diesel Exhaust Fluid (DEF) Lamp
•
The Diesel Exhaust Fluid Lamp alerts the operator that the DEF is
low and SHOULD be replenished.
•
When DEF level drops below 10% the DEF lamp illuminates. The
operator should now add DEF fluid.
•
When DEF level drops below 5% the DEF lamp starts flashing. The
engine power will de-rate to 25% which may cause the unit to shut
off due to engine over load.
•
When DEF level drops to 0% the DEF lamp continues flashing and
the engine will stop repeatedly.
•
When the machine is started again it is not possible to switch unit to
full load and engine runs at idle speed.
•
Refill at least 50% of DEF tank volume. After 3 minutes DEF tank
gauge level will show actual tank volume and red DEF lamp goes
OFF.
Exhaust System Cleaning Switch
The exhaust system cleaning switch provides operator control of the
exhaust cleaning system. When the switch is turned to the NORMAL
position (0), the engine ECM will automatically perform the exhaust
system cleaning when required. When the switch is turned to the
INITIATE position (Right), a request is sent to the engine ECM for a
manual cleaning of the exhaust system.
This manual cleaning will only happen when the engine ECM
determines conditions for cleaning are met. When the switch is turned
to the DISABLE position (Left), the engine ECM disallows any
automatic or manual (non-mission) cleaning of the exhaust system.
When the switch is turned to the DISABLE position (Left), the engine
ECM disallows any automatic or manual (non-mission) cleaning of the
exhaust system.
Important Notes:
The DOC is a maintenance free device and will under normal
conditions remain operational for as long as the engine.
The DEF system requires maintenance of the filter situated in the
Bosch dosing pump at the required intervals (see scheduled
maintenance).
Using any fluid other then the proper DEF fluid will contaminate and
render the dosing system inoperable causing the engine to stop.
Should any contamination occur, then the tank needs to be removed
and cleaned before filling with the correct DEF fluid.
DEF fluid should only be used from clean receptacles or filtered
pumping systems.
Never use additives to change the DEF fluid properties.
AFTERTREATMENT PROTECTION AFFECTING COMPRESSOR
OPERATION
DEF Quality
Adequate DEF quality is essential to meet emission targets. If an issue
with the DEF quality is detected the system will warn the operator of
the issue by the use of warning lights. If the warnings are ignored the
engine derate will apply, resulting in lower compressor flow output.
DEF Equipment Tampering
When any hardware or performance issues cause the NOx emissions
to exceed the legislated limits, the operator is warned with the
respective engine fault codes. If the warnings are ignored, the
inducements will start.
NOTE:
Switch returns from INITIATE position to NORMAL position
automatically.

WARNING: Continued use of the Exhaust System Cleaning
Inhibit position will at first lead to warning messages being
displayed on the Midport. Failure to respond with a return to the
Normal switch position will eventually create a severe engine
power derate and shutdown, running in this condition until
shutdown could also damage the SCR core requiring
replacement instead of cleaning.
WARNING: The ultimate engine protection level will be activated
after several restarts with the incorrect DEF quality in the DEF
tank and requires a Cummins technician to reset protection
parameters to allow engine restart.
