The main component of the Operator Control Panel (OCP) is the electronic control module (ECM). This section discusses the display, keys, and indicators on the control system panel of the ECM. The OCP 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
- Displaying Suspect Parameter Number (SPN) and Failure Mode Identifier (FMI) information for events
- Programming set points for the standard OCP (The set points for optional modules are set with the use of Cat ET).
- Annunciator configuration is done within the OCP
The following components can be found on the front panel of the ECM:
- Information Display
- Alarm Indicators
- Alarm Acknowledge/Silence Key
- Event Reset Key
- Function Keys
- Navigation Keys
- System Overview Keys
(1) Display Screen - Information from the OCP is displayed on the display screen. This screen is used for the following programming and display functions.
- Displaying engine parameter information
- Programming set points for the engine
- Displaying engine event information
- Displaying event codes from other modules
- Programming the display preferences of the OCP
- Changing password levels of the OCP
(10) Alarm Acknowledge/Silence Key - Pressing the alarm acknowledge/silence key will cause the horn relay output to turn off and silence the horn. Press the key (10) to cause any yellow or red flashing lights to turn off. Press the key (10) to cause flashing lights to become solid depending on the active status of the alarms. The alarm acknowledge/silence key may also be configured to send out a global alarm silence on the J1939 Data Link. The silence function will silence horns on annunciators. However, other modules must be configured in order to listen to the global acknowledge.
(11) Event Reset Key - The event reset button will clear all inactive fault conditions.
Yellow Warning Light - The yellow warning light (10) is located directly above the alarm acknowledge/silence key (11). A flashing yellow light indicates that there is an unacknowledged active warning. A solid yellow light indicates that there are acknowledged warnings active. If there are any active warnings, the yellow light will change from flashing yellow to solid yellow after the alarm acknowledge/silence key is pressed. If there are no longer any active warnings, the yellow light will turn off after the alarm acknowledge/silence key is pressed.
Red Shutdown Light - The red shutdown (12) light is located directly above the event reset key (13). A flashing red light indicates that there are unacknowledged active shutdown events. A solid red light indicates that there are acknowledged shutdown events active. If there are any active shutdown events, the red light will change from flashing red to solid red after the alarm acknowledge/silence key is pressed. Any condition that has caused a shutdown event must be manually reset. If there are no longer any active shutdown events, the red light will turn off.
(2) F4 - Pressing the F4 key will enable the function that is described on the screen directly above this key. When this key is defined on screen to scroll up or down, the Scroll Up and Scroll Down keys will also function the same.
(3) F3 - Pressing the F3 key will enable the function that is described on the screen directly above this key. When this key is defined on screen to scroll up or down, the Scroll Up and Scroll Down keys will also function the same.
(4) F2 - Pressing the F2 key will enable the function that is described on the screen directly above this key. When this key is defined on screen to scroll up or down, the Scroll Up and Scroll Down keys will also function the same.
(5) F1 - Pressing the F1 key will enable the function that is described on the screen directly above this key. When this key is defined on screen to scroll up or down, the Scroll Up and Scroll Down keys will also function the same.
(15) RUN - Pressing the "RUN" key causes the OCP to enter the run mode.
(16) AUTO - Pressing the "AUTO" key causes the OCP to enter the auto mode.
(17) STOP - Pressing the "STOP" key causes the OCP to enter the stop mode or the cool down mode.
(18) 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 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.
(21) OK Key - The OK 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 OK key during set point programming causes set point changes to be saved to memory.
(6) Control Key - The control key will navigate the display to the screen that allows the user to monitor and/or adjust the speed control of the engine.
(9) Main Menu Key - The main menu will navigate the display to the main menu directly without having to navigate out of menus.
(14) Event Log - The event log button will navigate the display to the event log.
(19) 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.
(20) 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 has a check mark, then pressing the key will cause the check mark to disappear. If the box does not have a check mark, then pressing the key will cause a check mark to appear inside the box.
(22) 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.
(23) 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 has a check mark, then pressing the key will cause the check mark to disappear. If the box does not have a check mark, then pressing the key will cause a check mark to appear inside the box.
(7) AUX Overview - AUX is meant to be a open ended button that could be used for compressor, fire pump or other applications.
(8) Engine Overview - Pressing the engine overview key displays the menu of engine information.
