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 - mini-
mum 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.
INHIBIT DPF REGENERATION
When running in an environment where an elevated
exhaust temperature is not allowed, it might be necessary
to inhibit DPF regeneration. This has to be done at
Customer Service Level. Go to General settings 1000.
Parameter 1142 ECU DPF Regeneration Enable - Set to
“OFF”. The controller has now put the DPF Regeneration
in a FORCED OFF mode, which is Inhibit DPF
Regeneration.
The compressor controller will communicate with the
engine controller and the (RED) Inhibit DPF regeneration
icon will appear:
When the controller gets powered down, it will (at next
power up) fall back to its default settings, meaning
AUTOMATIC DPF regeneration.
INCREASING SOOT LOAD
When the DPF Regeneration is Inhibited, or when the
engine does not get sufficient possibility to automatically
perform a full DPF Regeneration, the Soot Load will
exceed the normal levels.
The controller will show the DPF Regeneration Needed
Icon. In case of Inhibited DPF Regeneration, the DPF
Regeneration Needed Icon will overwrite the DPF
Inhibited Icon.
Required Action:
• Force DPF Regeneration, see paragraph FORCE
DPF REGENERATION
When DPF Regeneration is started, the DPF Regeneration
Needed icon will disappear and the HEST icon will pop-
up.
A full DPF Regeneration can take up to an
hour.
DPF Regeneration Inhibited.
