necessary to set the setpoint
Basic settings
:
COM1 Mode
= CUMMINS.
Loss of communication causes a warning alarm. On the contrary the ECU can be switched off at
quiescent engine that means not-communicating ECU is in that moment normal situation. All values
from ECU shall show ####, but no alarm is displayed. The output
ECU Comm OK
follows the real
situation which means it is not active anytime when the ECU does not communicate.
The output
ECU PowerRelay
closes at the beginning of prestart and opens if the engine shall be
stopped. It can be used to switch the ECU on and off. If the putput is configured but not active the
ECU communication alarm is blocked.
The engine is started via standard contact output or via CAN bus depending on ECU capabilities.
Values read from ECU
There is fixed set of values read from J1939 ECU by IL-NT controller:
Î
Engine speed (frame EEC1)
Î
Engine oil pressure (frame Engine Fluid Level/Pressure)
Î
Engine coolant temperature (frame Engine Temperature)
Î
Total engine hours (frame Engine Hours, Revolutions)
Î
Fuel rate (frame Fuel Economy)
Î
Boost pressure (frame Inlet/Exhaust Conditions)
Î
Intake manifold 1 temperature (frame Inlet/Exhaust Conditions)
Î
Engine oil temperature 1 (frame Engine Temperature 1)
When “Cummins-Modbus” option is selected, following values are read from Modbus Register Data
(for QSX15,QSK45, QSK60):
Î
Engine Speed (Register Address:30001)
Î
Oil Pressure (Register Address:30003)
Î
Coolant Temperature (Register Address:30002)
Î
Engine Running Time (Register Address:30008-30009)
Î
Fuel Consumption Rate (Register Address:30018)
Î
Intake Manifold Absolute Pressure (Register Address:30530 (QSK45, QSK60 only))
Î
Intake Manifold Temperature (Register Address:30531 (QSK45, QSK60 only))
Hint:
Values read from ECU are not written to history besides the fault codes.
Diagnostic messages read from ECU
Diagnostic messages are read and displayed in extra ECU Alarm list. For Standard J1939 SPN
(Suspect Parameter Number), FMI (Failure Mode Identifier) and OC (Occurrence Counter) are shown
together with text description if available.
One SPN (Suspect Parameter Number) / FMI (Failure Mode Identify) couple describes one fail
information. If FMI is equal to 0 or 1, WRN is displayed in the ECU Alarm list. For any other FMI
values, FLS is displayed.
Detail SPN/FMI code specification see in:
•
SAE Truck and Bus Control and Communications Network Standards Manual, SAE HS-1939
Publication
•
Or refer to corresponding engine manufacturer’s ECU error codes list.
Complete list of text diagnostic messages for each ECU can be found in
Comap Electronic Engines
Support
manual.
Hint:
InteliLite controller doesn’t support J1587 diagnostic line on Volvo engines. This can cause in some
cases a J1939 alarm message FC:000608 due to missing J1587 bus. Contact your Volvo distributor to
update ECU firmware.
For Scania engines the fault codes are displayed in hexadecimal format.
