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. This controller works in cooperation with
the ECU to display this information as well as provide an interface between the operator and ECU.
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 this is the normal engine operation where the elimination of soot and ash is
accomplished by the current engine speed and load.
1 – Auto at this level, the ECU enables automatic active regeneration due to the
current soot and 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).
4 – Service Regen the Kubota Service Regen Required prompt will appear. At this stage, a
service technician is required to perform a regen.
5 – Service Required the engine requires service by an authorized dealer.
