11.1 System Diagnostics
Your DLC contains extensive diagnostics that allow it to determine the source of common problems. If
your DLC is not operating properly, your first course of action should be to review the
{DIAGNOSTICS} sub-menu in the {CONFIGURE} menu. To access this menu from the standard
operating mode follow this procedure (provided your user interface -- keypad and display -- is
functioning)]:
1. Press [MOTOR] repeatedly until the display reads {MOTOR OFF}.
2. Cycle power to the DLC (turn the main OFF then ON). This will cause the self-test routine to re-
execute.
3. Press [MENU]. The screen { - MENU - / DIAGNOSTICS-1} will appear. The value, in this case '1'
indicates how many failures were detected.
4. Press [ENTER] to enter the Diagnostics Menu. The screen {DIAG MENU 1/8 / POWER IN: OK}
will appear.
5. Repeatedly press [UP] to cycle through all eight Diagnostic screens.
6. If a screen displays a FAIL message, press [ENTER] to display the time and date the failure occurred.
Press [ENTER] again to display the clear screen. Press [UP] and then [ENTER] to clear the message.
Make a note of any failures reported in the Diagnostics Menu. Using this information, proceed with
the troubleshooting instructions below:
Other actions may be necessary to bring the process back to normal conditions before clearing a
failure.
