⑤ Auto regeneration mode operation
▶Fire hazard!
During the Diesel Particulate Filter (DPF) forced regeneration process the exhaust
stack and fixed hood area becomes extremely hot. Park the machine outside and
away from combustible or highly flammable material.
Failure to comply could result in death or serious injury.
Warning
z In this operational mode, the operator does not
have to take any actions, the system is activated
automatically by the engine electronic controller.
NOTE : Auto regeneration is the normal operating
mode.
z The following conditions will activate the
burner.;
- When Soot load is 60% or more of capacity.
- Every four hours after last regeneration.
- When engine operating temperature reaches
designated regeneration temperature, set by
engine controller.
- When DPF inhibited switch is NOT ON.
NOTE : Duration of burner operation is
approximately 30 to 40 minutes.
z During the regeneration operation, the (DPF)
regeneration indicator light (1) and (DPF)
temperature Indicator light (2) will both be
illuminated.
▶If engine is turned off during regeneration mode, soot will not be completely burned
and may increase fuel consumption. KEY-OFF during regeneration mode is not
recommendable because too short operation won’t finish regeneration mode, So,
we recommend to users to operate until all indicator lights are “OFF” without Key
switch OFF.
NOTICE
▶During DPF hot shut down, the fuel pump will continue to run to cool components in
the fuel circuit. If there are any errors during this cooling action, the engine will not
run. Start engine after this cooling operation has completed. This will lead to longer
crank times before the engine runs. After heavy work of tractor, allow engine to run
at idle for approximately five minutes to allow fuel system to cool down.
NOTICE
z Depending on the soot rate of the (DPF) regeneration indicator light will show several different
blinking frequencies during the regeneration process. See previous page.
z The engine warning indicator light (3) will blink when there is a excessive soot load in the (PDF).
Stop working tractor and prepare for (DPF) regeneration.
z In case of turning off the engine running during regeneration mode, The regeneration is to resume
again when restarting the engine.
