The main component of the Electronic Modular Control Panel 4.2 (EMCP 4.2) is the Electronic Control Module (ECM). This section discusses the display, keys, and indicators on the control system panel of the ECM. The EMCP 4.2 panel is used for monitoring and controlling many of the generator set functions. Some of the functions include:
Sending start and stop signals to the engine
Providing visual and audible indications when warning or shutdown events occur
Displaying engine information and AC generator set information
Displaying Suspect Parameter Number (SPN) and Failure Mode Identifier (FMI) information for events
Programming set points for the standard EMCP 4.2 (The set points for optional modules are set with the use of Cat ET).

(1) Display Screen - Information from the EMCP 4 is displayed on the display screen. This screen is used for the following programming and display functions.
Displaying AC parameter information of the generator set
Displaying engine parameter information of the generator set
Programming set points for the generator
Displaying engine event information
Displaying event codes from other modules
Programming the display preferences of the EMCP 4.2
Changing password levels of the EMCP 4.2Alarm Indicators
(2) Yellow Warning Lamp - A solidly illuminated yellow warning lamp indicates that there are acknowledged warnings that are still present. A flashing yellow warning lamp indicates that there are unacknowledged warnings that are still present. To verify the warnings, press the alarm acknowledge/silence key (5). If there are no longer any active warnings, then the lamp will turn off. If active warnings still exist, then the lamp will change from flashing yellow to solid yellow. (3) Red Shutdown Lamp - A solidly illuminated red shutdown lamp indicates that there are acknowledged shutdown events that are still active. A flashing red shutdown lamp indicates that there are unacknowledged active shutdown events. To verify the shutdown events, press the alarm acknowledge/silence key (5). If the condition that caused the shutdown has been cleared, and the acknowledge/silence key (5) has been pressed, then the lamp will change from flashing red to solid red.Note: Any condition that has caused a shutdown event must be manually reset.Reference: Systems Operation, "Event Resetting"Alarm Acknowledge/Silence Key
(5) Alarm Acknowledge/Silence - Pressing the alarm acknowledge/silence key causes the horn relay output to turn off, which silences the horn. When the alarm acknowledge key is pressed, a global acknowledge command is transmitted on the CAN data link. Other modules may be configured to respond to the global acknowledge signal. When the horn relay sounds, one or both of the alarm lamps will begin to flash. Depending on the active status of the alarms when this key is pressed,
