Oil Mist Detector
1. General
The engine has an oil mist detection system. The system includes the sensors (2) and
the control unit (1) on the engine (see Fig. 1).
A display unit (8) is installed in the control room (Fig. 2).
The sensors (2) are installed on the fuel side of the engine for:
D Each cylinder of the divided crankcase
D The supply unit drive
D The supply unit.
The oil mist detection system continuously monitors the concentration of oil mist in the
crankcase, supply unit drive and the supply unit. If there is a high oil mist
concentration, the oil mist detector activates an alarm.
Damage to the bearings is quickly found and explosions in the crankcase are
prevented (see also 0460−1 Instructions about the Prevention of Crankcase
Explosions).
2. Function
Each sensor (2) optically monitors the concentration of oil mist. Each sensor (2) has a
self-test function to make sure that there are no internal faults.
Data communication is between the control unit (1) and the display unit (8)
(see Fig. 2).
The adjustments can be programmed in the display unit (8).
The menu-driven software has three user levels:
D User: Read-only of data.
D Operator: Password-protected level for access to most adjustments
and functions.
D Service: Password-protected level for authorized staff of the
manufacturer and service personnel.
Note: Instructions that relate to adjustments, commissioning, troubleshooting,
and maintenance are given in the related documentation of the
manufacturer.
