*ECU-controlled engine support
There exists only one firmware branch for both standard and electronic controlled (monitored)
engines.
Presence of the ECU on the CAN bus/RS232 is configured via LiteEdit like other peripheries (iG-IOM,
iGL-RA15). Pressing the
button in Configuration window of LiteEdit (version 2.0 and higher),
opens ECU dialog window where the appropriate engine/ECU type should be selected. There are
three groups of engine/ECU types:
•
Standard J1939 engines
•
Scania S6
•
Cummins-MODBUS
If the connected engine is Cummins communicating via RS232, it is necessary to set the setpoint
Basic settings
:
RS232 mode
= CUMMINSMB.
Loss of communication causes shutdown of the running engine. 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 CommOK
follows the real situation, that means it is not active anytime when the ECU does not communicate.
The output
ECU PwrRelay
closes at the beginning of prestart and opens if the engine shall be
stopped.
The engine is started via standard contact output or via CAN bus (for Volvo and Scania engines). For
other engines J1939 is used for monitoring only.
