Engine Interface Module (EIM)
The Engine Interface Module (EIM) is the central connection box on the engine. Covers the entire mini-
mum scope of a marine engine. Has no controls or parts requiring maintenance.
Functions:
• Starter control (start repetition, tooth alignment, starter protection)
• Generator monitoring
• Open bus interface to the plant (SAE J1939)
• Emergency stop function with line break monitoring
• Redundant power supply
• Optional control of emergency air-shutoff flaps
• 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 is connected to the engine wiring harness via a
62-pole Tyco connector X52. The second part comprises signals at higher current levels. These signals
are led out via M threaded pins and also connected to the engine wiring harness.
Functions
• ECU supply
• EMU supply
• Plant signals (ECU7 connector X1)
• Bus interface (2x MCS5 CAN)
• CAN dialog output (1xMCS5 CAN)
• ECU and EMU emergency stop
• Electric starter
• Terminal 45 of starter A/B (starter engaged)
• Pneumatic starter
• Start-air pressure valve
• Start-air pressure sensor
• Barring gear (barring gear 1 and 2)
• Generator (with excitation control)
• Optional shut-down air flaps
• Control SSK 1+2
• Feedback SSK 1+2
Electronic Engine Control Unit (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;
• RS 232 interface for connection of MTU dialog unit.
Electronic Engine Monitoring Unit (EMU), optional
Functions:
• Data processing logistics for analog and binary signals;
• Interface for data transfer to CAN field bus for remote control and ship-side monitoring.
