OPERATING INSTRUCTIONS 55
12/154
Normal Operation – Manual regeneration required:
DPF lamp indicates to the operator that the filter requires a
manual active regeneration to clear a build-up of excessive PM
soot.
Active regeneration is enabled - but duty cycle conditions prevent
regeneration from occurring due to low exhaust temperatures. This will
be a very infrequent occurrence.
However, at the next convenient opportunity (such as end of shift)
the operator should park the equipment and initiate a manual
regeneration when it is safe to do so.
Normal Operation – Regeneration Inhibit:
Regeneration DISABLE position should only be selected if the
compressor is to be used in a location that could be considered
hazardous if the engine ECM initiates active regeneration (increased
exhaust temperatures).
