MAN B&W MODUL Multi-Purpose Controller
Part/Type: 1142075-2
Revision: 1.57
Serial Number: OT11481012636
1. Manufacturer & Origin
-
Manufacturer: MAN Energy Solutions (formerly MAN Diesel & Turbo).
-
Product Line: MAN B&W, specifically for their two-stroke marine diesel engines.
2. Product Type & Function
This is a MODUL-type Multi-Purpose Controller (MPC). It is a critical component of the ME/ME-C engine control system, which is the electronically controlled common-rail system for MAN B&W low-speed engines.
-
Primary Role: It acts as a sophisticated, modular I/O (Input/Output) and processing unit within the Engine Control System (ECS).
-
Typical Functions: An MPC like this collects signals from various engine sensors (e.g., temperatures, pressures, positions) and, based on pre-programmed logic and commands from the main Engine Control Unit (ECU), controls actuators such as:
-
Cylinder Lubricators
-
Exhaust Valve Actuators
-
Fuel Injection Control Valves
-
Auxiliary Blowers
-
Start/Stop Valves
-
It handles both analog and digital signals.
-
3. Model & Revision Details
-
Model Number 1142075-2: This is the specific part number for this MPC module. The “-2” suffix often indicates a specific variant or hardware version.
-
Revision 1.57: This is a crucial identifier. It refers to the software/firmware revision loaded on the controller’s processor. The functionality, parameters, and compatibility of the MPC are determined by this revision. It must be compatible with the software revisions of the other ECS components (like the ECU).
4. Serial Number
-
S/N: OT11481012636: This unique identifier is used for:
-
Traceability: Tracking manufacturing date, batch, and quality control.
-
Service & Support: When ordering spare parts or seeking technical help from MAN, this number is essential.
-
Documentation: Linking the physical unit to its specific test certificates and as-built documentation.
-
5. Typical Physical Description
While exact dimensions require a datasheet, these MPC modules are typically:
-
Housed in a sturdy, rectangular metal casing for EMC protection.
-
Feature multiple electrical connectors (e.g., circular, D-sub) for field wiring, power, and communication (CAN bus).
-
Have status LEDs to indicate power, communication, and I/O activity.
-
Designed for mounting on a DIN rail or panel inside the engine control box.
6. Importance & Application
This controller is a key part of ensuring the engine operates efficiently, safely, and in compliance with emissions regulations (like IMO Tier II/III). A fault in this unit can lead to engine performance issues, alarms, or even shutdowns.
