The regeneration lamp turns on when the DPF soot level exceeds 100%
l
The regeneration lamp blinks when the DPF soot level exceeds 105%
l
The regeneration lamp blinks slowly, the CE lamp turns on and the engine power is
reduced (25%) when the DPF soot level exceeds 111%
l
The regeneration lamp blinks quickly, the CE lamp turns on and the engine power is
reduced (50%) when the DPF soot level exceeds 121%
DPF regeneration consists of passive and active regeneration while driving and forced
regeneration is activated manually by the operator.
When the DPF soot level is less than 105%, active regeneration is activated manually
while driving. However, at 105% or higher the system notifies the operator that forced
regeneration must be performed manually. At 120% or higher the engine warning light
lamp turns on, engine power drops 50% and the operator must call for service.
l
DPF soot level 105% or less: Active regeneration
l
DPF soot level 105%-120%: Forced regeneration + decrease in engine power
l
DPF soot level 105%-120%: Notify the operator that forced regeneration needs to
be performed
l
DPF soot level 120% or higher: Regeneration is not possible/must call for service to
regeration the DPF
