Lubricating oil temperature at the inlet
CAUTION
Machine damage
Machine damage may result if the oil temperature at the oil inlet ex-
ceeds the permissible range.
 Keep the oil temperature at the oil inlet as specified in the following
table.

Permissible
30 … 105 °C
Temporarily permissible (< 1 h) → alarm > 105 °C
Not permissible → stop engine

Not permissible → do not start engine (before
starting: preheat oil)
< 30 °C
Lubricating oil temperature at the outlet
The oil temperature at the outlet depends mainly on:
 lubricating oil temperature and pressure at the oil inlet
 engine load and turbocharger speed
 exhaust gas temperature
The maximum permissible oil temperature at the outlet is listed in the fol-
lowing table. The specified oil outlet temperature must be regarded as an
alarm value for turbocharger operation and be monitored in accordance
with standard regulations.

If the turbocharger has been operated outside the permissible range for a
prolonged period of time, ABB Turbo Systems recommends having the
turbocharger inspected by an ABB Turbocharging Service Station.
