Explanations regarding the rating plate
The recommended inspection and replacement intervals and the corresponding operating
limits are jointly defined with the enginebuilder. This information is specific to the system.
Operation above the indicated values n
Bmax
, t
Bmax
can considerably shorten the recommended
replacement intervals. In such cases, we recommend contacting the nearest ABB Turbochar-
ging Service Station.
n
Mmax
, t
Mmax
normally apply only when running at overload (110%) during trials on the engine
test bed. These limit values can also be permitted during operation for special applications.
Operation above n
Mmax
and t
Mmax
is not permitted.
Non-observance of the recommended inspection and replacement intervals increases the
risk of unpredictable component failures.
