EMCP 3 control system panel (1) Display screen (2) Yellow warning lamp (3) Red shutdown lamp (4) Alarm acknowledge/silence key (5) Lamp test key (6) Stop key (7) Auto key (8) Run key (9) Escape key (10) Enter key (11) Right key (12) Down key (13) Up key (14) Left key (15) Engine overview key (16) AC overview key The engine and generator set points are programmed in the EMCP 3 at the factory. The set points that are stored in the EMCP 3 must match the specified set points of the particular generator set. The set points, which are programmable, affect the following:
Proper operation of the engine
Serviceability of the engine
The accuracy of the information that is shown on the display screen (1) The set points may require modification when the EMCP 3 is moved from one engine to another engine. The set points may also require modification in order to satisfy the requirements of the installation.Function and Navigation Keys
The keys listed below are used for programming the EMCP 3 and navigating within the menu structure.ReferenceRefer to Systems Operation, "Electronic Control Module (Generator Set)" for a full explanation of the use of the function keys such as enter and escape. Refer to Systems Operation, "Electronic Control Module (Generator Set)" full explanation of the navigation keys such as scroll left, scroll right, scroll up, scroll down. (9) Escape - Used to navigate up (backward) through the menu structure and to return from the data entry screens during set point programming. (10) Enter key - Select a highlighted menu item or save a programmed value. (11) Scroll Right key - During numeric data entry, choose the digit to edit. During certain setpoint adjustments, select or deselect a check box. (12) Scroll Down key - Move down through the main menu or navigate within a list in order to highlight one of the items. Also used to decrement digits (0-9). (13) Scroll Up key - Move up through the main menu or navigate within a list in order to highlight one of the items. Also used to increment digits (0-9). (14) Scroll Left key - During numeric data entry, choose the digit to edit. During certain setpoint adjustments, select or deselect a check box.EMCP 3.x Programming Example
Note: The following programming example is not intended as a standard or as a preferred method of use. The example is presented here only as an example of the logical flow for programming. For consistency of terminology, a "normally closed" switch is a switch that is closed prior to installation, not being acted upon. A "normally open" switch is a switch that is open prior to installation not being acted upon. The example outlines the steps for wiring a low fuel level shutdown float switch to "Digital Input #3".In this example, the "Active Low" configuration will be used. The example will assume the use of a normally open switch that closes when the fuel
