Engine Interface Module (EIM)
The Engine Interface Module (EIM) is the central connection box on the engine. It covers the complete
minimum scope of a marine engine. It does not comprise control elements of components requiring
maintenance.
Functions:
• Starter control (start repetition, tooth alignment, starter protection)
• Monitoring of the battery-charging generator
• Open bus interface to the plant (SAE J1939)
• Emergency stop function with line break monitoring
• Redundant supply voltage input
• Emergency shutoff flap control (option)
• Key switch logic
• Interface to ECU and EMU
• MCS5 dialog interface
• Control of an MTU lube-oil priming pump (power components in separate MTU PPC Box)
• Connection facility for an MTU Local Operating Station (LOS)
• Serial RS422 interface for diagnosis
The engine interface comprises two parts. The first part of signals is integrated in the engine wiring har-
ness with a 62-pole Tyco connector X52. The second part refers to signals associated with higher cur-
rents. These signals are led out via M threaded bolts and also integrated in the engine wiring harness.
Functions
• ECU supply
• EMU supply
• Plant signals (ECU7 connector X1)
• Bus interface (2x MCS5 CAN)
• CAN dialog output (1xMCS5 CAN)
• Emergency stop from EMU and ECU
• Electric starter
• Terminal 45 starter A/B (engaged)
• Pneumatic starter
• Start-air pressure valve
• Start-air pressure sensor
• Barring device (barring gear 1 and 2)
• Battery-charging generator (with exciter control)
• Optional emergency air shutoff flaps
• Activation signal to air shutoff flaps 1+2
• Feedback signal from air shutoff flaps 1+2
Electronic engine governor (ECU)
Functions:
• Engine speed control with fuel and speed limitation dependent on engine status and operating condi-
tions
• Control of sequential turbocharging, cylinder bank cut-out and air recirculation function.
• Data processing logistics for analog and binary signals
• Interface for data transfer to CAN field bus for remote control and ship-side monitoring
