Note: To re-enable the regeneration, cycle the engine start switch key or press and hold down the force regeneration switch for 2 seconds. If the soot level is above 15%, an active regeneration will begin if you are within the low speed automatic regeneration window.Note: If the engine start switch key is cycled while the regeneration system is disabled via the disable regeneration switch, press and hold the disable regeneration switch for 2 seconds to re-initiate the disable regeneration.Soot Level Monitoring
Illustration 1 g02228033The soot level monitor indicates the level of soot that has accumulated within the DPF. The five marks on the monitor represent a percentage of soot within the DPF. The first mark indicates 0% soot level. The second mark indicates 25% soot level. The middle mark indicates 50% soot level. The fourth mark indicates 75% soot level. The last mark indicates 100% soot level. The soot level monitor can be used to optimize DPF regenerations based upon the work cycle of your machine. If machine conditions do not allow for an automatic regeneration, a forced regeneration should be performed before the soot level gauge indicates 100%. Note: Some machines will display soot level as a percentage and will not use a graphical depiction as displayed above.Modes of Regeneration
Automatic: An automatic regeneration is allowed between approximately 30% and 100% on the soot level monitor. There are two types of automatic regeneration, low speed automatic and high speed automatic.
Forced: A forced regeneration is initiated by pressing the force regeneration switch. A forced regeneration is allowed when the soot level is equal to or greater than 15%. The machine must be brought to a low idle speed in order to perform a forced regeneration.
Disabled: When the regeneration system is in disabled mode, automatic regenerations will not be performed.

the engine must be at a state of low idle, refer to illustration 2. Machine should be stationary . Engaging the parking brake or hydraulic lock will ensure the quickest start time for regeneration. If low idle speed is less than 1000 rpm, engine speed will automatically increase to between 1000 and 1400 rpm to activate regeneration.Load on engine should be minimal. Soot percentage must be between 30% and 100% on the soot monitor.Low speed automatic regenerations are ideal in environments where interruptions in the work cycle of the machine are not a problem. By utilizing low speed regenerations, the duration of the regeneration will be shortest and less fuel will be consumed by the aftertreatment regeneration device when low speed regenerations are used.High Speed Automatic Regeneration (2)
Engine can be operating between approximately 1400 rpm and 2200 rpmEngine load factor can be anywhere between 30% and 85%Soot load percentage will be between 60 and 75% when this type of regeneration is available.High speed automatic regenerations are ideal for situations where interruptions in the work cycle are not acceptable.
