Standstill regeneration
±
Temperatures of approx. 600 °C occur on the exhaust pipe during regeneration. A special engine operating state
becomes active during standstill regeneration and the machine is not allowed to be used during the active standstill
regeneration. Danger of burns!
If the support mode does not attain an adequate reduction of the soot contamination, the filter will continue to become
contaminated with soot and a standstill regeneration will be necessary. This is displayed by a flashing regeneration lamp.
The standstill regeneration must be initiated by the operator. We recommend carrying out a necessary standstill
regeneration as quickly as possible, as otherwise the diesel particle filter will continue to become contaminated with soot.
If the standstill regeneration is not carried out, the engine control unit will activate the specified engine protection functions,
depending on the contamination of the diesel particle filter. Every standstill regeneration slightly dilutes the engine oil with
fuel. The number of standstill regenerations is therefore monitored.
Implementation of the standstill regeneration
The engine must be brought into a «safe state» for the regeneration:
• Shut down the engine on an open terrain at a safe distance to
flammable objects.
• Warm up the engine; the coolant temperature must reach at least
75°C.
• Operate the engine in idling.
• The engine control unit now requires a signal indicating that the
unit is safely parked (stationary signal). This occurs, depending on
the application, for ex-ample by: – Activating the parking brake.
• Operating the release button. Position depends on application,
see device manual. The regeneration lamp lights up continuously.
Once the standstill regeneration has been released, the engine automatically increases the speed level. Using the
device during standstill regeneration is prohibited. The regeneration lasts 35 to 40 minutes on average. The standstill
regeneration can be interrupted at any time by pressing the regeneration button again or by removing the
regeneration release. Using the device during standstill regeneration also leads to it being interrupted. The request for
standstill regeneration remains until it is completed without interruption. Certain engine faults lead to excessive
carbon emission which cannot be seen due to the diesel particle filter. In such cases, the diesel particle filter can be
loaded very quickly, among other things, to a level which no longer allows a standstill regeneration by the opera-tor.
Very short intervals between two standstill regenerations (<10h) can be an indication of such a defect. Please contact
the DEUTZ service. The regeneration lamp goes out when regeneration has been successfully completed. If the
standstill regeneration request is not observed and the DPF is overloaded to an impermissible level, then the filter can
only be regenerated via the DEUTZ service.
Replacing the diesel particle filter
It may be necessary to replace the diesel particle filter after a high filter running time as non-combustible residues
accumulate in the filter - so-called ash.
If the ash loading goes beyond a certain level, this will be indicated by the ash lamp.
The diesel particle filter needs to be replaced
The machine can operate normally until the replacement is carried out by the service.
The time interval between two regeneration requests is shortened in proportion to the run time. Please contact your DEUTZ
partner DEUTZ particle filters come with a catalysing coating, so require a special cleaning procedure to prevent damage to
the coating.
The DEUTZ filter replacement programme guarantees that the filter medium is properly cleaned, and the medium fully
functions and performs as if it were a new part!
