lock the system and select ”Start” in the
regeneration menu on the IC (Instrument Cluster).
NOTE!
The operator can start the regeneration
immediately by pressing the SELECT button on the
IC (Instrument Cluster) control keypad when an
alarm indication for regeneration pops up on the IC
(Instrument Cluster).
NOTE!
Make sure that there is no flammable material
around the machine, especially in the engine
compartment before starting the regeneration, this
is important to prevent risk of fire. Clean all
flammable materials from the machine. See pages
278
,
332
and
334
for detailed information.
During regeneration, the HEST (High exhaust
temperature) lamp is on, see symbol. This is to
indicate that regeneration is in progress and that the
exhaust temperature has increased. Do not turn off
the engine while the HEST lamp is on.
NOTE!
The machine must be in an area that is not heat-
sensitive while the symbol is lit.
Service regeneration
If a requested regeneration is delayed for too long,
the PM (particulate matter)-load in the DPF (diesel
particulate filter) and the amount of sulphur in the
SCR (selective catalytic reduction) will be too high
for a safe parked regeneration. Then regeneration
must be started with Volvo's service tool in order to
perform a safe regeneration.
Fuel consumption
During a parked regeneration, the fuel consumption
may increase.
Delaying regeneration
The operator can delay the regeneration by
pressing the ESC button on the IC (Instrument
Cluster) control keypad when an alarm indication
for regeneration pops up on the IC (Instrument
Cluster). The alarm indication will pop up again after
15 minutes or when the engine is restarted.
Delayed regeneration may be useful if the machine
is in a heat-sensitive environment.
