EMCP3 Caterpillar

Real Time Clock Programming

Usage:

The real-time clock provides accurate information for the time and the date of an automatic time-based start/stop control. The real-time clock provides a mechanism for time stamps in the event log.

Note: The EMCP 3.1 does not utilize a real-time clock for time stamping.

The EMCP 3.1 tracks the time and the date using an internal real-time clock with an internal battery backed up memory. The time and the date will be maintained by the internal battery even when the control battery power is disconnected.

After the internal battery fails, the real-time clock will continue to keep time only when the control battery power is connected. If the control battery power is disconnected, then the real-time clock must be reprogrammed when the EMCP 3 is powered up again.

Function and Navigation Keys

Reference: The call outs in this section are related to the EMCP 3 control panel illustration in the Systems Operation, RENR7902, "Electronic Control Module (Generator Set)" section.

The keys listed below are used for programming the EMCP 3 and navigating within the menu structure.

Reference: Refer to Systems Operation, RENR7902, "Electronic Control Module (Generator Set)" section for an explanation of the function keys and the navigation keys. The function keys include the enter and escape keys. The navigation keys include the scroll left, scroll right, scroll up, and scroll down) keys.

Escape (9) - Used to navigate up (backward) through the menu structure and to back out of data entry screens during set point programming.

Enter key (10) - Select a highlighted menu item or save a programmed value.

Scroll Right key (11) - During numeric data entry, choose the digit to edit. During certain set point adjustments, select or deselect a check box.

Scroll Down key (12) - 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).

Scroll Up key (13) - 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).

Scroll Left key (14) - During numeric data entry, choose the digit to edit. During certain set point adjustments, select or deselect a check box.
