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
Note: In operation an Indicator can have two states, on solid and flashing. The sequence is to give a visual indication of the importance of the warning. Some application may also have an audible warning installed.Ensure that the engine maintenance is carried out at the correct intervals. A lack of maintenance can result in illumination of the warning Indicators. For the correct intervals of maintenance, refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule".

Indicator Operation
Aftertreatment Indicator Aftertreatment Indicator State Warning Indicator Warning Indicator State Description Action Required
All indicators are checked at key on. Any indicator illuminate after 2 seconds must be investigated. Any indicator that has not illuminated must be investigated.
OFF OFF OFF OFF Normal operation None
During passive regeneration NO indicators will be illuminated.
Regeneration active ON OFF OFF The indicator shows that elevated emission temperatures are possible.
The indicator will stay illuminated during regeneration. None
Regeneration active ON OFF OFF Active regeneration occurring
DPF ON OFF OFF
Level 1
DPF ON OFF OFF Indication of soot loading An active regeneration required
Level 2
DPF ON solid Amber Indicator Flashing Soot loading has increased Perform a forced regeneration, or a service regeneration will be required.
Level 3
DPF ON solid Amber Indicator Flashing The flashing warning indicator will indicate that the engine has continued to be operated
The STOP warning indicator will indicate that the engine will be derated and will be shut down.
After 30 seconds the engine will automatically shut down. The engine can be restarted but will only run for 30 seconds before shutting down again. A forced regeneration is required.
Hold the forced regeneration switch for 10 seconds before a regeneration begins. If Regeneration cannot occur, contact your Cat dealer.
