Interrupting automatic regeneration manually
If automatic regeneration starts while the machine is in the direct vicinity of
easily flammable material, interrupt regeneration manually with the rocker
switch 49.
The rocker switch 49 is located in switch panel 2. The rocker switch has
three settings:
• Position 0 = OFF.
• Position I = interrupts regeneration of the diesel particulate filter.
• Position II = triggers a manual regeneration of the diesel particulate
filter.
Interrupt regeneration:
• Press and hold the rocker switch 49 at least 3 seconds in position I.
➥ Automatic regeneration is interrupted.
- Control lamp 28 illuminates.
- Control lamp 29 goes out.
If automatic regeneration has been interrupted manually, then there are
the following possibilities:
• Manual regeneration can be triggered – see "Manual regeneration" on
page 1-77.
• After restarting the engine, automatic regeneration starts again as
soon as the engine reaches its operating temperature.
Regeneration stops if it is interrupted manually, or if the ignition switch key
is moved to position 0 during regeneration. This has the effect that the
soot particles are not removed from the diesel particulate filter. The
following regeneration then takes longer.
Repeatedly interrupting regeneration can cause damage to the diesel
particulate filter/engine.
► Once regeneration has started, finish it without any interruption, if
possible.
► Interrupt regeneration manually only in exceptional cases, for example,
if the vehicle is in the direct vicinity of easily flammable material.
► Once it has started, do not interrupt regeneration more than once.
Reduced engine output
The load in the diesel particulate filter increases due to multiple
interruptions of the regeneration. From a load of more than 100%, the
engine automatically lowers the engine output. A maximum of 1800 rpm
or a maximum torque of 50% is available.
In the display, the control lamp illuminates 27 and the control lamp 22
flashes.
If this regeneration is interrupted again, the engine independently
switches off every 30 seconds.
The diesel particulate filter must be replaced by authorized Perkins
distribution partners.
