Operation Manual / 4 Product description / A200-L4 Monitoring during operation / 4.1 Oil pressure, oil temperature© Copyright 2018 ABB. All rights reserved. HZTL4036_EN Revision M August 2018Lubricating oil temperature at the outletThe oil temperature at the outlet is mainly dependant on:¡ Lubricating oil temperature and pressure at the oil inlet¡ Engine load and turbocharger speed¡ Exhaust gas temperatureThe maximum admissible oil temperature at the outlet is listed in the following table. Thespecified oil outlet temperature is to be considered as alarm value for the turbocharger op-eration and must be monitored according to the current regulations.Status for operation Oil temperature at the inletToil,inlet [°C]Oil temperature at the outletToil,outlet [°C]Admissible 45 ≤ 110Admissible 85 ≤ 130Temporarily admissible → alarm 45 > 110Temporarily admissible → alarm 85 > 130Not admissible → stop engine 45 > 120Not admissible → stop engine 85 > 140Table 8: Lubricating oil temperature at the outletIf the turbocharger was operated for a longer period of time outside of the admissiblerange, ABB Turbo Systems recommends to have the turbocharger inspected by an ABB Tur-bocharging Service Station.4.1.1 Pre-lubrication and post-lubricationCAUTIONPre-lubricationSerious damage to engine or property can result if the turbocharger is notsupplied with oil from the first moment after starting the engine.u Activate the pre-lubrication device each time before starting the engine.The pre-lubrication time is at least 5 minutes.The post-lubrication time is at least 10 minutes.If the engine is operated for 5 to 10 minutes in idle mode before stopping, no additionalpost-lubrication is required.Page 17 / 108
