Troubleshooting Checklist
The following checklist provides a general procedure for diagnosing the
controller and its supporting modules. If you follow this checklist,
you’ll be able to identify many of the problems that occur in a typical
installation. When you’ve identified the problem, use Table 4–1 to
confirm your diagnosis and fix the problem.
If your initial diagnosis points to several possible causes, use the tools
described later in this chapter to further refine your diagnosis. If the
problem can’t be diagnosed using the checklist and tools, call customer
service for additional support.
To troubleshoot the controller and its supporting modules:
1. Check the power to the cabinet and its components. Are the cords
properly connected? Is the power within specifications?
2. Check the component cables. Are the bus cables to the controllers
connected properly? Are the ECB cables properly connected?
3. Check the program cards to ensure they’re fully seated.
4. Check the operator control panel and devices for LED codes. See
Appendix C, “LED Codes,” to interpret the LED codes.
5. Connect a local terminal to the controller and check its configuration
with the following command:
SHOW THIS_CONTROLLER FULL
Ensure that the ACS version is correct and that pertinent patches have
been installed. Also, check the status of the cache module and its ECB.
In a dual redundant configuration, check the other controller with the
following command:
SHOW OTHER_CONTROLLER FULL
6. Using FMU, check for last failure or memory-system failure entries.
Show these codes and translate the last failure codes they contain.
“Significant Event Reporting,” page 4–14.
If the controller has failed to the extent that it cannot support a local
terminal for FMU, check the host’s error log for the instance or last-
failure codes. See Appendix D, “Event Reporting: Templates and
Codes,” to interpret the event codes.
