Regeneration
Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) is used to regenerate the DPF. The DPF traps both soot and ash. The ash is removed through a manual cleaning process. Refer to Operation and Maintenance Manual, "Diesel Particulate Filter - Clean" for more information on the service of the DPF. Types of Regeneration
Passive Regeneration - The engine conditions are sufficient for regeneration. The rate of regeneration is much lower than active regeneration. Active Regeneration - The engine duty cycle conditions are not sufficient for passive regeneration to occur.Regeneration Indicators
Five Indicators can be affected by the DPF regeneration. Note: Amber or yellow Warning Indicator can be use as a diagnostic Indicator. For more information refer to this Operation and Maintenance Manual, "Diagnostic Lamp".
Regeneration Active - The Indicator is illuminated during active regeneration. The Indicator will stay on until the aftertreatment has cooled.
DPF - This Indicator provides a general indication of the soot load. The Indicator is off when the soot load is normal. Note: If the Indicator is illuminated, a regeneration will be required.
Regeneration Disable - This Indicator is illuminated whenever the disable switch is activated or the system has been disabled by the engine ECM.
Amber or Yellow Warning - This Indicator, indicates that the soot load has increased. Regeneration is required. Also, the DPF Indicator will be illuminated. A flashing indicator will cause an engine derate.
Red Stop - This Indicator, indicates that the soot load is extremely high. The soot load is at level 3. The DPF Indicator will be illuminated and the amber warning indicator will be flashing. The engine will be shut down.Regeneration Switch
The regeneration switch has three position force regeneration, automatic regeneration, and disable regeneration.Note: Some OEMs may have other means of activating a forced regeneration such as touch screen interface.Note: The MIDDLE position of the regeneration switch is the default position for automatic mode of regeneration.
Force Regeneration - Press in the top of the switch for 2 seconds in order to begin regeneration. An indicator light on the switch will become active showing that the regeneration is active. The regeneration active Indicator will become active showing that the regeneration is active.
Disable Regeneration - Press in the bottom of the switch for 2 seconds in order to disable regeneration. An indicator light on the switch will become active. The disable indicator will illuminate. Note: To re-enable the regeneration, cycle the engine start switch key or press and hold down the force regeneration switch for 2 seconds.Modes of Regeneration
Automatic
Forced RegenerationAutomatic regeneration is controlled by the engine ECM. Automatic - Automatic regeneration allows for the DPF regeneration to start automatically with up to 80 percent load on the engine. In order for an automatic regeneration to occur, the following conditions must be met:
Refer to OEM for the applications interlocks required to be engaged before regeneration can take place.Forced regeneration - A forced regeneration is initiated by pressing the regeneration switch. Soot Level Monitoring and Indicators
