Analog inputs
It is possible to configure on each Analog input:

Reading from IL Analog inputs or from Engine Control Unit via CAN bus (J1939)

Sensor characteristics
– from the list, or custom sensor curve

Value dimension (e.g. psi - bars,

F -

C, % - l)

Sensor resolution
Warning and shut-down limits are adjusted in Engine Protect setpoints group.
The analog inputs are configurable. Use LiteEdit software to modify configuration. Default
configuration is:
Oil Pressure
Oil pressure analog input. Default range 0 to 10.0 bars.
Water Temp
Water temperature analog input. Default range 40 to 120

C.
Fuel Level
Fuel Level analog input. Default VDO sensor 0-180R = 0-100%
Hint:
For further information about analog inputs configuration see Analog inputs .
For correct calculation of statistics value TotFuelConsum, Dim in Sensor characteristics must be in
[%], sensor range 0 - 100% (0% empty tank
– 100% full tank).
CAN J1939 interface
Following values can be received from Engine Control Unit via CAN bus instead of measuring on IL-
NT terminals when J1939 interface is enabled.
Value Value is received from
J1939 enabled J1939 disabled
RPM ECU IL-NT
– RPM terminals
Oil pressure ECU or IL-NT AI1 IL-NT AI1 terminals
Water temperature ECU or IL-NT AI2 IL-NT AI2 terminals
Fuel Level
ECU or IL-NT AI3 IL-NT AI3 terminals
ECU State ECU
Fuel Rate ECU
Manifold temp ECU
Boost Pressure ECU
Percent Load ECU
Use LiteEdit to enable/disable J1939 interface and to configure IL-NT analog inputs.
Hint:
RPM reading is automatically switched to pickup or generator voltage measuring (depends on Basic
Settings : Gear Teeth value) if J1939 fails.
Analog outputs
Optional plug in card IL-NT AOU8 provides eight Pulse-With-Modulation (PWM) outputs. These are
intended to drive VDO style analog gauges. This is to provide visual indication of typically ECU values
without installing additional sensors on the engine. PWM signal emulates sensor which would be
typically mounted on the engine.
Any value from controller may be configured to the outputs. Use LiteEdit PC SW to configure
corresponding sensor/gauge curve and value selection.
