DPF Regen Display Status
•
OFF: When OFF, passive regeneration is underway.
•
AUTO: Automatic regeneration is underway.
•
PARKED MODE: Machine functions are locked out, preparation for a
forced regeneration.
Passive Regeneration
The DPF is self-cleaning and generally requires no operator action. Passive
regeneration means the engine is operating at a high enough temperature
(more than 570°F/300°C) to burn particulate as it is created, and none is
being emitted.
Automatic Regeneration
When particulate matter builds up, the engine regenerates automatically. Machine operation is not interrupted.
NOTICE:
Coolant temperature must be 150°F (65°C) or higher for an automatic regeneration to occur.
Inhibited (Disabled) Regeneration
Inhibit (disable) regeneration
only
if high exhaust temperatures pose a fire hazard, such as in confined spaces.
Scroll to “Inhibit Regen”
(7)
and press
Enter Key
to turn it ON.
Certain engine conditions also inhibit regeneration:
•
out of neutral
•
park brake off
•
low exhaust temperature
•
engine cold
If regeneration is underway and the throttle is adjusted, regeneration will be interrupted.
