The main component of the Electronic Modular Control Panel 4.1/4.2 (EMCP 4.1/4.2) is the Electronic Control Module (ECM). This section discusses the display, keys, and indicators on the control system panel of the ECM. The EMCP 4.1 and EMCP 4.2 panels are 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 4.1/4.2 (The set points for optional modules are set with the use of Cat ET).
- RS-485 Annunciator configuration (EMCP 4.2 only)
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 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 4.1/4.2
- Changing password levels of the EMCP 4.1/4.2
(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.

(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, the flashing lamp(s) will either turn off or solidly illuminate. The alarm acknowledge key always sends out a global acknowledge, however other modules must be configured to listen to the global acknowledge.
(8) RUN - Pressing the "RUN" key causes the EMCP 4.1/4.2 to enter the run mode.
(9) AUTO - Pressing the "AUTO" key causes the EMCP 4.1/4.2 to enter the auto mode.
(10) STOP - Pressing the "STOP" key causes the EMCP 4.1/4.2 to enter the stop mode or cooldown mode.
(11) Escape Key - The escape key is used during menu navigation 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 to cancel out of 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.
(14) OK Key - The "OK" key is used during menu navigation to move forward (downward) through the menu/submenu structure. The key is also used during set point programming to save set points changes. Pressing the OK key during set point programming causes set point changes to be saved to memory.
(12) Up Key - The up key is used 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 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.
(13) Right Key - The right key is used during set point adjustment. During numeric data entry, the key is used to choose which digit is being edited. The key is also used during certain set point adjustments to select a check box or to deselect a check box. If a box has a check mark inside of the box, then pressing the key will cause the check mark to disappear. If the box does not have a check mark inside of the box, then pressing the key will cause a check mark to appear inside the box.
(15) Down Key - The down key is used 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 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.
(16) Left Key - The left key is used during set point adjustment. During numeric data entry, the key is used to choose which digit is being edited. The key is also used during certain set point adjustments to select a check box or to deselect a check box. If a box has a check mark inside of the box, then pressing the key will cause the check mark to disappear. If the box does not have a check mark inside of the box, then pressing the key will cause a check mark to appear inside the box.
(2) 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 multiple times.
(3) 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 multiple times.
