Regeneration
The regeneration process is controlled by the engine ECU. The engine ECU monitors emissions
parameters such as soot level and ash level. When the engine ECU determines that a regeneration is
necessary, it initiates the regeneration process which requires the engine to operate at a designated
speed for a designated period of time as determined by the engine ECU. The engine ECU
communicates the need for a regeneration via the regeneration lamp on the panel.
When the engine ECU initiates a regeneration, the yellow DPF (Diesel Particulate Filter) lamp will
illuminate with the display message shown above. The operator can press the ENTER button (for
Yes) to allow the regeneration to initiate or the MENU button (for No) to delay the regeneration
process to a later time. Answering “No” only delays the regeneration process. The regeneration
lamp stays illuminated and regen request prompts continue as long as the engine ECU determines a
regeneration is required.
Over time, the engine ECU increases the level of severity through both lamp indications and display
messages.
Levels of severity:
1)
Lowest Level
2)
Moderate Level
3)
High Level
4)
Warning Level
5)
Service Regen Level
At the lowest level, the DFP lamp illuminates.
As the levels increase, the DFP lamp begins to
blink. As the levels continue to increase the
yellow alarm lamp illuminates.
