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)

Serial RS422 interface for diagnosis
The engine interface is divided into two parts. The first part is integrated in the engine wiring harness via the
62-pole Tyco connector X52. The second part is formed by those signals involving a higher current. Such
signals are routed out via M threaded pins and are also integrated in the engine wiring harness.
