EMR 2
System Functions
4.1 Overview features
Feature Chapter Description
Speed control 4.3
As variable speed, idling/end or fixed speed governor; choice
of switchable governor features during operation, freezing
the current speed, fixed speed governor for network
synchronization or load distribution, overdrive speed
Set point input 4.4
By means of
!
Pedal sensor and/or hand throttle
!
External voltage signal (0 - 5 V)
!
CAN Bus (remote electronics)
!
Fixed speed signal (genset operation)
!
Pulse width modulation (PWM)
!
Touch control operation Up/Down (digital)
Optimal adaptation to different applications
Torque limitation 4.5
Up to three performance curves can be set independently of
each other within the framework of the engine limits
Governor behaviour (speed
droop)
4.6
Constant, variable or switchable speed droop from 0 - 80 %
for adaptation to the application
Engine Start/Stop 4.7
Engine switch-off by means of EMR actuator (additional
safety using switch-off solenoid possible)
Monitoring and signal
output functions
4.8
Coolant temperature and level, oil pressure, charge air
temperature, fuel temperature
→
fault display and/or
performance reduction or engine switch-off for engine
protection
LDA function 4.9
Smoke limitation through charge air pressure and/or
temperature-dependent limitation of the adjustment speed of
the injection
Temperature-dependent
start control
4.10
Improving the starting ability, gentle cold start without smoke
ejection
Altitude correction 4.13 Engine protection because of reduced air pressure
Fuel volume correction 4.14 Compensation for loss of performance due to fuel heating
Emergency running 4.15
Emergency running after failure of set point signal (e.g. using
accelerator pedal), the charge air sensor or the vehicle speed
signal
Selection of cold
start help installations
4.16
Failure of auxiliary control units, EMR 2 controls a selection
of heating flange, glow plugs or flame starting apparatus
Data communication 5 Interfaces, diagnostics and programming
Output of fault
fault blink codes
7.2 Simplified fault diagnosis
