DIESEL PARTICULATE FILTER
REGENERATION
When the Diesel Particle Filter regeneration process
is kept at its default ‘AUTOMATIC’ setting, then the
DPF regeneration will be performed automatically
when the Soot Load exceeds 60%.
The controller display will indicate an ongoing DPF
Regeneration by showing the HEST icon (High
Exhaust System Temperature):
The DPF regeneration process will continue, until the
Soot Load has become as low as possible, or until the
engine is stopped.
When the DPF regeneration process is stopped, the
HEST icon will disappear from the display.
AUTOMATIC DPF REGENERATION
(DEFAULT)
In specific cases, when the engine speed is constant at
Minimum RPM, it can happen that the DPF
regeneration already starts from 30% Soot Load (LSR
- Low Speed Regeneration).
This can happen in following situations:
Warming Up
Not Loaded
Loaded (when running in Unload condition -
minimum RPM)
Cooldown
When an LSR is ongoing while the soot load is less
than 60%, and the engine speed changes (engine is
stopped, machine gets loaded, …), then the DPF
Regeneration process will be stopped.
If the Soot Load is higher than 30% when cooling
down should start (then an LSR is expected to be
started) the controller will ask:
If Enter is pressed within 10 seconds then the
controller will allow the DPF regeneration to be
completed before the engine is stopped.
If Enter is not pressed (within 10 seconds), then the
engine will be stopped after cooling down.
