Engine Interface Module (EIM)
The Engine Interface Module (EIM) is the central connection box on the engine. It covers the entire minimum
scope of a marine engine. It has no controls or parts requiring maintenance.
Functions:
• Start control (start repetition tooth-on-tooth, starter protection)
• Battery-charging generator monitoring
• 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)
The engine interface comprises two parts. The first part is integrated in the engine wiring harness via a Tyco
connector X52, 62-pin. 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 (ECU9 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)
Electronic Engine Control Unit (ECU)
Functions:
• Engine speed control with fuel and speed limitation according to engine status and operating conditions
• 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
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
Electronic Gear Control Unit (GCU), ship-side wall-mounting
Functions:
• Date processing logistics for gear coupling control
• Input/output signals as well as data transfer to CAN field bus for remote control and ship-side monitoring
Monitoring in engine room
Engine control and monitoring unit (LOP)
