EMCP3 Caterpillar

A flashing red shutdown lamp (3) indicates that there is an unacknowledged shutdown event. The lamp will change from flashing red to solid red when the Alarm Acknowledge key (4) is pressed.

Shutdown events can only be reset when the shutdown events are described as "Active". Use the following procedure in order to reset the active shutdown events.

Note: The following instructions do not apply to the EMCP 3 that is listed as "GENSET CONTROL" in the event log.

Resetting All Events for a Single Module

1. Press the stop key (6).

   Note: The control must be in "STOP" in order to reset active shutdown events.

2. Use the scroll down key (12) in order to navigate from "MAIN MENU" to "EVENT LOG".

3. Press the enter key (10). An "ACTIVE EVENTS" screen will be displayed that will list the electronic control modules that are connected to the system. The total number of active events for an ECM is listed to the right of the ECM. Refer to Illustration 6.

4. Use the scroll down key in order to highlight an ECM that has active events. Refer to Illustration 6.

5. Press the enter key in order to display the active events for the selected ECM. Refer to Illustration 7.

   Note: The events are sorted. Present events are placed at the top of the log, then active events, and finally inactive events. Within each of these groups, events are sorted by time and date with the most recent events at the top of each group. If a real-time clock time stamp is not available, then events are sorted based on the engine hours.

6. Scroll through the events in order to highlight an active event.

7. Ensure that the condition which caused the event is no longer present and then press the enter key.

   If the condition that caused the event is no longer present, and the control is in "STOP", then "RESET ALL" will be highlighted.

8. Press the enter key again. The fault will clear. If there are no other active shutdown events, then the red shutdown lamp will turn off.

   Note: Modules other than the EMCP 3 do not distinguish between "PRESENT" and "Active" events. If the "RESET ALL" does not reset all of the events when the enter key is pressed, then the condition that is causing the event, that is being viewed, may still be present. For example, if the engine shutdown due to a low coolant level fault, then the "Low Coolant Level Shutdown" event will not reset until the coolant level has been filled to the required level.

9. Repeat steps 4 through 8 until there are no active shutdown events remaining. When all active shutdown events have been reset, then the Red Shutdown Lamp will be turned off.

10. Press the escape key (9) three times in order to return to the "MAIN MENU" screen.

Reset Individual Events from the Generator Set Control

1. Press the STOP key (6).

   Note: The control must be in "STOP" in order to reset active shutdown events.

2. Use the scroll down key (12) in order to navigate from the "MAIN MENU" to the "EVENT LOG" menu.

5. Press the enter key in order to display the active events for the selected ECM. Refer to Illustration 7.

   Note: The events are sorted from top to bottom. For example, the highest priority events will be listed at the top of the event log.

   The state of the event , the priority level, and the event types that are associated with a specific event are listed in Table 1.

6. Scroll through the events in order to highlight an active event.

7. Ensure that the condition which caused the event is no longer present and then press the enter key.

   If the condition that caused the event is no longer present, and the control is in "STOP", then "RESET" will be highlighted.

8. Press the enter key again. The fault will clear. If there are no other active shutdown events, then the red shutdown lamp will turn off.

9. Repeat steps 4 through 8 until there are no active shutdown events remaining. When all active shutdown events have been reset, then the red shutdown lamp will be turned off.

10. Press the escape key (9) three times in order to return to the "MAIN MENU" screen.

Resetting All Events for All Modules

1. Ensure that the control is "Stopped".

2. Execute the following from any screen. Press the "ACKNOWLEDGE" key and hold the "ACKNOWLEDGE" key for approximately 5 seconds.

3. A confirmation prompt will appear.

4. Press the enter key in order to continue to "RESET" all events on all of the modules. Press the escape key in order to "CANCEL" the reset operation.

Note: "Reset All Events" will not reset "Present" events! For example, if the "E-Stop" switch is pressed and an EMERGENCY STOP SWITCH ACTIVATED SHUTDOWN is present. The event cannot be reset until the "E-Stop" is pulled out and the event status changes from "PRESENT" to "ACTIVE".

Resetting Events for Engines Without J1939 Support

The EMCP 3 generator set control (GSC) support that is provided for engine events, depends on the type of engine ECM. The configuration of the EMCP 3 GSC includes the following set points:

• Engine type configuration

• Engine control J1939 data link support configuration

The functionality that is available for the different types of engine ECM is shown in Table 2.

The EMCP 3 GSC can reset all events for electronic engines with no J1939 support. The reset is accomplished by the use of a relay output.

Three conditions must be satisfied in order for the reset to work.

1. One of the digital selectors must be configured for "ECU Fault Reset". Refer to the "Digital Selector Options" information for a list of options that relate to the digital selectors.

2. The corresponding relay output must be wired to a corresponding "Fault Reset I/O" pin on the engine ECM or the relay must be set up to power cycle the ECM.

3. The EMCP 3 GSC set points that are shown in Table 2 must be set properly. The "Engine Type Configuration" must be set to "Electronic". The "Engine Control J1939 Data Link Support" must be set to "NO J1939 SUPPORT". If the "Engine Control J1939 Data Link Support" is set to "NO J1939 SUPPORT", then the engine control will not be listed in the EMCP 3 GSC display event log. However, there will be an option to "RESET ALL ENGINE EVENTS". If the enter key is pressed with the "RESET ALL ENGINE EVENTS" option selected, the "ECU FAULT RESET" will be activated. The "ECU FAULT RESET" will activate the corresponding relay output. The "ECU FAULT RESET" will trigger the engine ECU to reset the faults or will cycle the power for the ECU.
