EMR 2
System Functions
4.9 LDA function
For mobile applications, the injection quantity for acceleration and dynamic load increase is limited with
reference to the charge air pressure (smoke quantity-characteristic field). Usage: protection of the exhaust
turbo supercharger and prevention of smoke ejection.
4.10 Temperature-dependent start control
In order to prevent smoke ejection and for optimizing the governing relationship, the start quantity, the
speed ramp and the governor parameters are controlled with reference to the temperature (required basic
function).
4.11 Speed throttling (input F 7)
This function is designed for a driving speed evaluation is accordance with DIN 11786.
4.12 Engine protection functions
All monitoring functions can be provided with a message lamp on the plant side (dependent on the scope of
the function and the pins that can be assigned).
Oil pressure monitoring
The user is warned by means of the message lamp when
!
the oil pressure has overstepped the warning limit and/or
!
after a pre-warning period, the performance has been reduced by the EMR 2, or
!
the oil pressure falls below the switch-off limit and, after a pre-warning period,
the engine is switched off.
Coolant temperature monitoring
The user is warned by means of the message lamp when
!
the temperature exceeds the warning limit and/or
!
after a pre-warning period, the performance has been reduced by the EMR 2, or
!
the temperature exceeds the switch-off limit and, after a pre-warning period,
the engine is switched off
Charge air monitoring
The user is warned by means of the message lamp when
!
the temperature exceeds the warning limit and/or
!
after a pre-warning period, the performance has been reduced by the EMR 2, or
!
The temperature exceeds the switch-off limit and after a pre-warning period, the engine is
switched off.
