Page 42: Commissioning After Taking Out Of Operation
Lubricants and pastes used during assembly can liquefy or vaporise and escape as oily fluids during the initial hours of operation. Continual escape of an oily fluid indicates an oil leak. If there is a leak, contact an ABB Turbocharging Service Station. Commissioning after taking out of operation...
Page 43: Monitoring During Operation
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 Turbocharging recommends installing a manometer "M". If the pressure is controlled electronically, the relevant signals should be triggered at the warning and alarm values.
