4 Monitoring during operation
4.1 Oil pressure, oil temperature
Lubricating oil pressure
CAUTION
Assuring lubricating oil pressure
Serious damage to engine or property can result from missing or insuffi-
cient lubricating oil supply.
u The lubricating oil pressure must be monitored during operation and the
necessary pressure assured at the oil inlet.
For monitoring the lubricating oil pressure, ABB Turbo Systems recommends installing a
manometer "M". If the pressure is controlled electronically, the appropriate signals are to be
triggered at the warning and alarm values.

The permitted oil pressure ranges at measuring point M of the turbocharger are listed be-
low.

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