*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 opens ECU dialog window
where the appropriate engine/ECU type should be selected. The actual list of ECU types is available
on ComAp website in "ECU list - x.y.iwe" package. Download this package and import it into LiteEdit in
the same way as standard firmware IWE package.
More information about ECU list packages, configuration and wiring recommendations can be found in
ComAp Electronic Engines Support
manual.
If the connected engine is Cummins with GCS engine control unit communicating via Modbus it is
necessary to set the setpoint
Basic settings
:
COM1 Mode
= ECU LINK or
COM2 Mode
= ECU LINK.
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 output is configured but not active the
ECU communication alarm is blocked.
