Navigation Keys
AC Overview (2) - The "AC OVERVIEW" key will navigate the display to the first screen of AC information. The "AC OVERVIEW" information contains various AC parameters that summarize the electrical operation of the generator set.
Engine Overview (3) - The "ENGINE OVERVIEW" key will navigate the display to the first screen of engine information. The "ENGINE OVERVIEW" information contains various engine parameters that summarize the operation of the generator set.
Main Menu Key (4) - The "MAIN MENU"key will navigate the display to the main menu directly without having to navigate out of menus.
Acknowledge Key (5) - Pressing the "ACKNOWLEDGE" key will cause the horn relay to turn off. The horn relay being turned off will silence the horn. Pressing the "ACKNOWLEDGE" key will also cause any red or yellow flashing lights to either turn off or to come on continuously. The "ACKNOWLEDGE" key may also be configured to send out a global alarm silence signal on the J1939 Data Link. Sending out a global alarm silence signal on the J1939 Data Link will silence the horns on the annunciators.
Reset Key (6) - Pressing the "RESET" key will reset various events.
Event Log Key (7) - Pressing the "EVENT LOG" key will navigate the display to the event log.
RUN Key (8) - Pressing the "RUN" key will start the engine.
AUTO Key (9) - Pressing the "AUTO" key will cause the engine to enter the "AUTO" mode. The engine will start if the module receives a start command from a remote source.
STOP Key (10) - Pressing the "STOP" key will stop the engine.
Escape Key (11) - The "ESCAPE" key is used in order to navigate through the menus. When the key is pressed, the user moves backward or the user moves upward through the menus. The "ESCAPE" key is also used to exit out of entering data when the user is programming the setpoints. If the "ESCAPE" key is pressed while the user is programming the setpoints, changes made on the screen will not be saved to memory.
Up Key (12) - The "UP" key is used to navigate through the various menus and monitoring screens. The "UP" key is also used when a setpoint is entered. When entering numeric data, the "UP" key is used in order to increment the digits (0-9). If the setpoint requires selection from a list, the "UP" key is used to navigate UP through the list.
Right Key (13) - The "RIGHT" key is used during setpoint adjustment. The "RIGHT" key is used to select which digit is edited while entering numeric data. The "RIGHT" key is also used during some setpoint adjustments in order to select or to unselect a check box. If a check box has a check mark, the function has been enabled. Pressing the "RIGHT" key will disable the function. Pressing the "RIGHT" key will also cause the check mark to disappear. If the check box does not have a check mark, the function is disabled. Pressing the "RIGHT" key will enable the function. Pressing the "RIGHT" key will also cause a check mark to appear.
Enter Key (14) - The "ENTER" key is used in order to navigate through the menus. When the key is pressed, the user moves forward or the user moves downward through the menus. The "ENTER" key is also used to save any changes while the setpoints are being programmed. Pressing the "OK" key during programming the setpoints causes the changes to be saved to memory.
Down Key (15) - The "DOWN" key is used to navigate downward through the various menus or screens. The "DOWN" key is also used to program the setpoints. The "DOWN" key is used to decrease the digits when entering numeric data. If the setpoint requires selection from a list, the "DOWN" key is used to navigate DOWN through the list.
Left Key (16) - The "LEFT" key is used during setpoint adjustment. The "LEFT" key is used to select the digit that is edited during the entry of numeric data. The "LEFT" key is also used during some of the setpoint adjustments to select a check box. The key is also used to unselect a check box. If a check box has a check mark, pressing the "LEFT" key will disable the function. Pressing the key will also remove the check mark. Pressing the "LEFT" key will also cause the check mark to disappear. If the check box does not have a check mark, pressing the "LEFT" key will enable the function. Pressing the "LEFT" key will also cause a check mark to appear.
Alarm Indicators
Yellow Warning Lamp - A yellow warning lamp is located above the "ACKNOWLEDGE" key. A flashing yellow light indicates that there are active warnings that have not been acknowledged. A continuous yellow light indicates that there are acknowledged warnings that are active. If there are any active warnings, the yellow light will change from flashing yellow to continuous yellow after the "ACKNOWLEDGE" key is pressed. If there are no longer any active warnings, the yellow light will turn off after the "ACKNOWLEDGE" key is pressed.
Red Shutdown Lamp - A red shutdown lamp is located above the "RESET" key. A flashing red light indicates that there are active shutdowns that have not been acknowledged. A continuous red light indicates that there are active shutdowns that have been acknowledged. If there are any active shutdowns, the red light will change from flashing red to continuous red after the "ACKNOWLEDGE" key is pressed. Any condition that has caused a shutdown must be manually reset. If there are no longer any active shutdowns, the red light will turn off.
Digital Inputs
There are several digital inputs and outputs on "EMCP 4.1" and "EMCP 4.2". For detailed information about the inputs on this electronic control module, see Systems Operation, Troubleshooting, Testing, and Adjusting, UENR1209, "EMCP4.1/4.2".

Starting Aid Auto/Manual Switch (1) - The starting aid switch is optional. The starting aid switch is used to inject ether into the engine when you are starting the engine in cold-weather conditions. When the starting aid switch is in the ON position, the solenoid valve is energized. The switch then meters a specific amount of ether into a holding chamber. When the starting aid switch is released, the solenoid releases the ether to the engine.
Panel Light Switch (2) - The panel lights switch turns on or the panel lights switch turns off the panel lights.
Emergency Stop Push Button (3) - The emergency stop push button (ESPB) is used to shut down the engine during an emergency situation. If equipped, the ESPB shuts off the fuel and the ESPB activates the optional air shutoff.
Voltage Adjust Switch (4) - This switch can be used to raise the voltage. The switch can also be used to lower the voltage.
Speed Potentiometer (5) - The speed potentiometer is optional. The speed potentiometer can be used with the generator set that has an electronic governor.
Customer Connection (6) - The customer connection is a 9-pin connector for connecting the Cat Electronic Technician.
Horn (7) - The horn provides an audible alarm.
Pump Run Switch (if equipped) (8) - Under normal circumstances, the fuel transfer process is automatic. In some instances, a manual operation may be required. Press the pump run switch once in order to start the pump manually.
Pump Stop Switch (if equipped) (9) - The pump stop switch is a push-button switch that locks into position. The pump stop switch will stop the pump if the switch is locked into position. Releasing the switch will place the pump back into the run mode.
