Emissions Monitoring - Regeneration
The engine ECU continuously monitors the engine’s emissions parameters. When certain
conditions are reached, the ECU will indicate that a regen is needed. The information can
be obtained by entering the Emissions Parameters menu (described above).
The regen status can be set to two different states, Auto or Regen Inhibit. When the unit
is in Regen Inhibit, the ECU will not be able to initiate a regen. This state should be used
sparingly and for a brief period of time. The default setting is Auto, which allows for the
ECU to initiate a regen. Regeneration is initiated and controlled solely by the engine ECU.
REGENERATION LEVELS
0 –
PASSIVE
the normal engine operation where the elimination of soot/ash is accom-
plished by the current engine speed and load.
1 –
AUTO
the ECU enables automatic active regeneration due to the current soot/ash
load. There is no effect on engine performance or operation during automatic active
regeneration. If the regen inhibit mode is activated, a “Disable Inhibit – Yes/No” prompt
will appear. As the regen continues to be inhibited, an “Auto Regen Needed” screen will
scroll with the standard screen.
2 –
AUTO/PARKED
as the soot/ash levels increase, the ECU may continue as in level 1,
or may send a Parked Regen request (DPF Lamp).
3 –
PARKED
the ECU will send prompts to the controller and light the DPF Lamp (see
below).
