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 will also send out a global alarm silence signal on the J1939 Data Link. Annunciators on the J1939 Data Link can be configured to silence their individual horns upon receipt of the global acknowledge.
Reset Key (6) - Pressing the "RESET" key will reset all events that can be reset currently (events that are PRESENT cannot be reset)..
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 put the generator set into a mode where it will attempt to start the engine except in cases where there are any active or present shutdown events.
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-start source.
STOP Key (10) - Pressing the "STOP" key will put the generator set into a mode where it stops the engine. Depending on the configuration, the set may run on for a cooldown period before stopping the engine.
Escape Key (11) - The "ESCAPE" key is used 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 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 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.
OK/enter Key (14) - The "ENTER" key is used 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.
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.
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, UENR7097, "EMCP4.2B".
