The main component of the "Electronic Modular Control Panel 3" (EMCP 3) is the "Electronic Control Module" (ECM). This section discusses the display, keys, and indicators on the control system panel of the ECM. The EMCP 3 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 3 (The set points for optional modules are set with the use of Cat ET.)
The following components can be found on the front panel of the ECM:
- Information Display
- Alarm Indicators
- Alarm Acknowledge/Silence Key
- Function Keys
- Navigation Keys
- System Overview Keys
(1) Display Screen - Information from the EMCP 3 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 3
- Changing password levels of the EMCP 3
(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. In order to verify the warnings, press the Alarm Acknowledge/Silence key (4). 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 - An 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. In order to verify the shutdown events, press the Alarm Acknowledge/Silence key (4). If there are no longer any active shutdown events, then the lamp will turn off. If active shutdown events still exist, then the lamp will change from flashing red to solid red.
Note: Any condition that has caused a shutdown event must be manually reset.

(4) Alarm Acknowledge/Silence - Pressing the Alarm Acknowledge/Silence key causes the horn relay output to turn off, which silences the alarm. 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 (2) or (3) will begin to flash. Depending on the active status of the alarms when this key is pressed, the flashing lamps will either turn off or will illuminate and remain on. The acknowledge alarm button always sends out a global acknowledge, however other modules must be configured in order to listen to the global acknowledge.
(5) Lamp Test - Pressing the lamp test key and holding the lamp test key will cause all of the LED indicators and the display screen pixels to illuminate. The LED indicators and the display screen pixels will remain illuminated until the key is released.
(6) STOP - Pressing the "STOP" key causes the EMCP 3 to enter the "STOP" mode.
(7) AUTO - Pressing the "AUTO" key causes the EMCP 3 to enter the "AUTO" mode.
(8) RUN - Pressing the "RUN" key causes the EMCP 3 to enter the "RUN" mode.
(9) Escape Key - The escape key is used during menu navigation in order to navigate up through the menu/submenu structure. Each key press causes the user to move backward (upward) through the menus. The escape key is also used in order to exit/cancel data entry screens during set point programming. If the escape key is pressed during set point programming, then none of the changes displayed on the screen will be saved to memory.
(10) Enter Key - The enter key is used during menu navigation in order to move forward (downward) through the menu/submenu structure. The key is also used during set point programming in order to save set points changes. Pressing the Enter key during set point programming causes set point changes to be saved to memory.
(11) Right Key - The right key is used during set point adjustment. During numeric data entry, the key is used in order to choose which digit is being edited. The key is also used during certain set point adjustments in order to select a check box or to deselect a check box. If a box is checked, then pressing the key will cause the check mark to disappear. If the box is not checked, then pressing the key will cause a check mark to appear inside the box.
(12) Down Key - The down key is used in order to navigate down through the various menus or monitoring screens. The key is also used during set point entry. During numeric data entry, the key is used in order to decrement the digits (0-9). If the set point requires selection from a list, then the key is used to navigate down through the list.
(13) Up Key - The up key is used in order to navigate up through the various menus or monitoring screens. The key is also used during set point entry. During numeric data entry, the key is used in order to increment the digits (0-9). If the set point requires selection from a list, then the key is used to navigate up through the list.
(14) Left Key - The left key is used during set point adjustment. During numeric data entry, the key is used in order to choose which digit is being edited. The key is also used during certain set point adjustments in order to select a check box or to deselect a check box. If a box is checked, then pressing the key will cause the check mark to disappear. If the box is not checked, then pressing the key will cause a check mark to appear inside the box.
(15) Engine Overview - Pressing the engine overview key displays the first screen of engine information. This initial information page contains various engine parameters that summarize the operation of the engine. Additional engine parameters can be viewed by pressing the "Down" key (12) multiple times.
(16) AC Overview - Pressing the AC overview key displays the first screen of AC information for the generator set. This initial information page contains various AC parameters that summarize the electrical operation of the generator set. Additional AC parameters can be viewed by pressing the down key (12) multiple times.
