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.
Fig. 17: Lubricating oil pressure measuring point
The permitted oil pressure ranges at measuring point M of the turbocharger are listed be-
low.
Status for operation

Warning signal: Temporarily admissible (<1 h )
Alarm signal: Not permissible. Stop the engine immediately
Table 8: Oil pressure range
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.
Observe oil temperature at the oil inlet according to the following table.
