In case of TRIPLE BLINKING RED, it is necessary to connect to BYBOX by means of the dedicated
software, to determinate which is the cause of the signalling (call the AC Service ).
Scheduled maintenance
A necessary condition for the BPF R620 system to work is to systematically follow the maintenance
plan specified by the vehicle/engine manufacturer.
It is necessary to guarantee that:
The smoke opacity of the exhaust gases measured upstream of the filter is lower than 1.7 K [m-1]
The lube-oil consumption is lower than 0.25% of the fuel consumption.
The temperature of the exhaust gases at the inlet of the muffler must be kept above 350°C for at least
15% of the engine running time if BPF systems are used.
The temperature of the exhaust gases at the outlet of the muffler must be kept above 200°C for at
least 50%for BPF R620 systems.
Note
For achieving the functioning temperature profiles described above to favour/allow on board
regeneration of the particulate filter, it is suggested, when possible during the normal use of the
engine, to:
For circulating applications, bring the engine to full running load (at full power/driving under load
on a straight stretch of road at a constant speed, observing the speed limit, or on a section of road
going uphill).
For auxiliary engines, earth movement vehicles, or stationary applications, increase the power
demand from the hydraulics system or the other connected devices, to achieve full load on the engine.
In any case, this loading of the engine must be carried out for no more than 15 minutes.
