BAR AS 8E8955 - Caterpillar

The EMCP 4 shows previous and current events from both the EMCP and external modules. These events are organized into logs for each physical EMCP 4 module.The logs include the following:STATUS EVENTS - Recent event historyGENSET CONTROL - Events for the EMCP 4 GSCENGINE CONTROL - Events for a primary CAN data link compatible engine ECMDIGITAL AVR - Events for the Cat Digital Voltage Regulator (CDVR)THERMOCOUPLE - Events for the thermocouple moduleEXTERNAL I/O - Events for the discrete input/output (DIO) moduleRTD MODULE - Events for the resistive temperature device (RTD) moduleSCR MODULE - Events for engine after treatment systemsThe generator set control log stores events that are generated by the EMCP 4. Any other event is stored within the module that generated the event. Even if the EMCP annunciates an event, that does not mean that the EMCP logs that event. The event may be within the log of another module.Each log is visible only if the module is connected to the appropriate data link. The module must be connected to either the primary data link or the accessory data link. The module must be communicating with the EMCP 4.The list of event logs can be viewed by pressing the "Event Log" key or via the "VIEW" submenu. Select the log that you wish to view and press the "OK" key to view the events.The EMCP 4 supports more than one instance of some of the above modules. Those modules are uniquely identified with a number at the end of the log name.The module number is software-configured, and is called the "ECU INSTANCE NUMBER". The ECU instance number can be viewed and modified by the Caterpillar service tool.An event in the EMCP 4 generator set control log can be in one of three states:
Present
Active
InactiveTable 1 explains the different states.
Table 1
Present This state is only applicable to the generator set control log. Present means that the condition that caused the event is still present. The condition must be addressed before the event can be reset.
This state only applies to Genset Control events. Other modules will not have present in logs.
Active The event was previously in a "Present" state, but event is no longer present. The event has been latched by the event system and needs to be reset before the engine can be restarted.
Within the generator set control log, the condition that caused the event is still affecting the system, but may be reset. Warning type events automatically reset when the condition that caused the event is resolved and will never be active.
Within any log other than the generator set control log, the condition that caused the event is affecting the system. The event may, or may not, be resettable. If the "Reset All" command fails to reset the event, then this event is still occurring. The event must be resolved before the event can be reset.
Many events go from present to active when the engine is shut down and may reoccur once the engine starts running again. Further
