4.2.9 Checking Selective Catalytic Regeneration Conditioning Mode

The selective catalytic regeneration (SCR) system is part of the exhaust aftertreatment system. The SCR conditioning
process can activate any time the windrower is running so long as the INHIBIT SCR CONDITIONING switch is set to OFF. The
functionality of the INHIBIT SCR CONDITIONING feature will need to be verified.
The SCR conditioning inhibit mode is off when indicator (A) on
™
the HarvestTouch Display is not highlighted.
If SCR conditioning mode is on, then indicator (A) will be
highlighted. This will prevent the SCR process from occurring.
NOTE:
If the SCR system is inhibited for an extended period, the engine
will begin to derate its power levels until manual SCR
conditioning is performed. Refer to the windrower operator's
manual for more information.
If the SCR conditioning inhibit symbol is highlighted, turn SCR
inhibit mode off as follows:
