MAN B&W S50ME-B9.3 -TII
Project Guide
Electronically Controlled
Two-stroke Engines
with Camshaft Controlled Exhaust Valves
This Project Guide is intended to provide the information necessary for the layout of a marine propulsion
plant.
The information is to be considered as preliminary. It is intended for the project stage only and subject to
modification in the interest of technical progress. The Project Guide provides the general technical data
available at the date of issue.
It should be noted that all figures, values, measurements or information about performance stated in this
project guide are for guidance only and should not be used for detailed design purposes or as a substi-
tute for specific drawings and instructions prepared for such purposes.
Data updates
Data not finally calculated at the time of issue is marked 'Available on request'. Such data may be made
available at a later date, however, for a specific project the data can be requested. Pages and table entries
marked 'Not applicable' represent an option, function or selection which is not valid.
The latest, most current version of the individual Project Guide sections are available on the Internet at:
www.marine.man.eu → 'Two-Stroke'.
Extent of Delivery
The final and binding design and outlines are to be supplied by our licensee, the engine maker, see Chap-
ter 20 of this Project Guide.
In order to facilitate negotiations between the yard, the engine maker and the customer, a set of 'Extent of
Delivery' forms is available in which the basic and the optional executions are specified.
Electronic versions
This Project Guide book and the 'Extent of Delivery' forms are available on the Internet at:
www.marine.man.eu → 'Two-Stroke', where they can be downloaded.

Questions and answers
ME Auxiliary Blower No.1 have no power supply, Auxiliary Blower is running , no issues
The ME Auxiliary Blower No.1 may have no power supply due to several possible causes:
1. Input Power Issues: The power supply systems (A or B) may not be receiving input voltage (100–240V AC or 110–240V AC), possibly due to disconnection or failure in the AC source.
2. Overcurrent Protection Activation: Input or output overcurrent protection may have triggered, cutting off the power.
3. Output Voltage Fault: The output voltage may be outside the normal 24V DC range (too high or too low), causing a shutdown.
4. UPS Battery Mode or Alarm: The system may be in UPS battery mode or showing an alarm such as “Batteries not available (fuse fail),” interrupting normal power supply.
5. Fuse Failure: A fuse failure could disconnect the power supply to the blower motor.
6. Control System Fault: A fault in the control panel or pressure switches may prevent the blower from receiving the run signal.
7. Blower Motor Issue: The electric motor may be faulty or disconnected, especially if not starting properly under Direct Online Start (DOL) conditions.
Each of these should be checked systematically to identify the root cause.
