Monitoring operation
4.1
Oil pressure, oil temperature
Lubricating oil pressure, oil inlet
CAUTION
Assuring lubricating oil pressure
Serious damage to engine or property can result from missing or insufficient
lubricating oil supply.
The lubricating oil pressure must be monitored during operation and the
necessary pressure assured at the oil inlet.

M Oil pressure measuring point
T Oil temperature measuring point
For monitoring the lubricating oil pressure, ABB Turbo Systems recommends installing an "M"
manometer immediately before the turbocharger. If the pressure is controlled electronically,
the appropriate signals are to be triggered at the warning and alarm values.
*) If the drain pipe is vented, the measuring point for lubricating oil temperature can be in-
stalled at the outlet in the vent tank. Otherwise the measurement should be taken in the drain
pipe as close to the turbocharger as possible.
NOTICE
Oil orifice at the oil inlet
To limit the oil flow rate through the turbocharger to the admissible values
with the engine at 100% load, an oil orifice is mandatory or has already been
fitted at the oil inlet of the bearing casing if the oil inlet pressure is > 3 bar.
