Engine protection and safety functions
• Restricting engine operation to remain within safe operating values
• Engine protection with dual-level safety systems
The following ECU responses including alarm signaling can be programmed:
– Start interlock
– Controlled torque reduction
– Torque limitation to an absolute value
– Torque limitation by deduction of a relative value
– Engine shutdown
• Engine safety shutdown (stop or emergency stop) in the event of limit violations and sensor defects, con-
figurable
• ESCM (Engine Side Condition Management)
Automatic engine power reduction for safety as a function of e.g.:
– Intake air temperature
– Operating site (e.g. altitude above sea level)
Engine monitoring for genset applications
• Engine speed
• Coolant temperature (HT and LT circuit)
• Coolant level (HT and LT circuit)
• Charge-air pressure (A and B sides)
• Charge-air temperature
• High-pressure fuel (rail)
• Fuel pressure after filter
• Fuel pressure before additional filter
• Fuel temperature (rail)
• Oil temperature
• Oil pressure, oil refill pump
• Lube oil pressure differential downstream of filter
• Crankcase pressure
• Turbocharger speed
• Leak fuel level
• Ambient air quality (humidity, temperature, pressure)
• Exhaust temperature (A and B sides)
• Exhaust temperature (throttle flap for thermal management, A and B sides)
• EIL (Engine Identification Label)
Additional components
SmartConnect
Upload and download of specific data and parameters
The following diagnostics data is generated:
• Mini display for showing fault codes
• Engine identification data (engine number, serial number,...)
• Control unit identification (serial number, part number, design status, CCS, ...)
• Software version identification (application, firmware, CCS, ...)
• Data logger for remote maintenance
Benefits
• Simple handling
• No MTU Service personnel required
EIL (Engine Identification Label)
• Identification of engine hardware
• Data storage, e.g. aging data
