Table 5: Oil pressure range
Depending on the design, metering orifices can be installed in the oil inlet of the low-pres-
sure and high-pressure stages in order to adjust the oil pressures.

Lubricating oil temperature
CAUTION
Machine damage
If the oil temperature at the oil inlet exceeds the admissible range, this may
lead to engine damage.

Table 6: Lubricating oil temperature
The specified maximum oil outlet temperature is considered to be an alarm value for the op-
eration of the low-pressure and high-pressure stage and must be monitored according to
the current regulations.
If the low-pressure or high-pressure stage has been operated outside of the admissible
range for a long period of time, ABB Turbocharging recommends having the low-pressure or
high-pressure stage inspected by an ABB Turbocharging Service Station.
