5.1

Oil pressure, oil temperature

Lubricating oil pressure
CAUTION
Assuring lubricating oil pressure
Serious damage to the engine or property can result from a missing or insuf-
ficient lubricating oil supply.
The lubricating oil pressure must be monitored during operation and the
u
necessary pressure assured at the oil inlet.
For monitoring the lubricating oil pressure, ABB Turbocharging recommends installing a
manometer "M". If the pressure is controlled electronically, the relevant signals should be
triggered at the warning and alarm values.

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