Machines with Aftertreatment Exhaust System
15.6 Conditioning the Aftertreatment Exhaust System (if equipped)
Overview Sustained operation of the generator under load heats the Selective Catalytic
Reduction (SCR) system to a temperature high enough to burn accumulated Diesel
Exhaust Fluid (DEF) crystals. This conditioning process normally occurs
automatically.
DEF crystals may fill the Decomposition Reactor Tube (DRT) if the engine runs at
idle for long periods with no load. An indicator
(a) on the control panel illuminates
when a conditioning is needed.
Procedure Perform the procedure below to condition the SCR system.
1. Start the engine at low idle speed.
2. Move the manual conditioning switch (b) to the “ON” position and hold it for five
seconds, then release the switch. The indicator will go out and the conditioning
process will begin.
The engine speed will gradually increase to about 1100 rpm while the machine is in
conditioning mode. When conditioning is complete, the engine speed will return to
low idle (about 900 rpm).
Note: The conditioning process may continue for up to one hour depending on
ambient conditions and the amount of DEF crystals inside the DRT.
NOTICE: To prevent machine damage, perform a manual conditioning as soon as
the indicator illuminates.
