FORCED REGENERATION ACTIVATION PROCEDURE
1. Ensure that the genset is in a well-ventilated outdoor
location.
If the fuel level indicator shows
2.
a low level, refuel the genset so that the
regeneration process is complete.
Disconnect all connected loads,
3.
the genset should run no load.
Press
4.
Regeneration button for at least 3 seconds
until the procedure starts.
The regeneration process will start
5.
if all requirements are met, in particular the temperature of
the coolant must be above 60°C.
6. The system will inform the operator when the regeneration
process is finished.
7. At any time it is possible to interrupt the process by pressing
the Regeneration Inhibit button or by switching off the
engine.
Warnings
• Forced regeneration should only be carried out if requested
by the ECU when the "ATT filter warning light" illuminates.
(from level 3 to 5 particulate accumulation).
• DO NOT perform forced regenerations if NOT requested by
the ECU (from Level 0 - 2 particle accumulation).
• Repeated forced regenerations cause severe fuel
contamination of the engine oil.
• If the regeneration inhibit function is abused, the level of
particulate accumulation will quickly increase.
• It is necessary to change the oil and engine oil filter with
every forced regeneration by KOHLER software (Particulate
accumulation of Level 5).
• The permissible fuel contamination in the engine oil is 3%
MAX.
• DO NOT operate any controls during the regeneration
process.
Regeneration inhibit button
If the power unit is used in a situation that is not suitable for
the high temperatures reached by the exhaust gases during
regeneration (e.g. working in areas with dry brushwood),
the system can be temporarily disabled. To disable DPF
regeneration, proceed as follows:
Press and
1.
Inhibit button for at least 3 seconds to
disable the
The disabling is indicated by the

activation of the "Regeneration inhibition light".
Once suitable conditions are restored, press
3.
the Regeneration Inhibit Button again to resume
Auto Regeneration. The "Regeneration Inhibit
Indicator Light" will change its status to inactive
and hold the Forced

Automatic regeneration.
ATS - AFTER TREATMENT SYSTEM
Warnings:
• The regeneration inhibit command is ignored by the system
if there is a request for manual regeneration (forced or
service)
• If the operator continues to operate the machine without
allowing Automatic regeneration, the system activates the
forced regeneration process with a possible reduction of
engine power.
• Be sure to reactivate "Automatic" regeneration as soon
as possible to avoid unnecessary formation of particulate
matter or soot in the DPF.
• DPF regeneration automatically returns to 'Automatic' mode
after each ignition.
Dummy load
The genset is equipped with a
resistive bank located in front of the
radiator that allows the system to
correctly perform all regeneration
processes, regardless of
electrical consumers connected
to the genset.
The activation of the dummy
load is automatically controlled
by the genset controller, which
continuously compares
regeneration signal from
engine with the electrical power
supplied by the generator,
determining whether or
the dummy load is activated.
No operation is required of the
operator to manage the dummy load.
DPF maintenance
The particulate filter is designed to retain the residual ash
generated during diesel combustion. This filter is capable of
operating for many hours without maintenance.
At some point, the particle filter will require professional
maintenance to remove the accumulated residue. The exact
number of hours of operation before maintenance is required
will vary depending on the engine power category, duty cycle,
operating conditions, and accumulated ash content. In any
case, the removal and disposal of the ashes contained in the
DPF must only be carried out by specialised personnel.
Warning:
DO NOT attempt in any way to remove the ashes using water
or other chemicals. Failure to follow the approved methods of
ash removal may damage the DPF, and may invalidate the
warranty.
Note:
Proper treatment is required for an exhaust gas filter that
has reached the end of its useful life, as ashes or catalyst
substances in the device may be classified as hazardous
waste under applicable local laws or regulations.
