Publication 1769-IN082A-EN-P - July 2008
OK (con’t) Steady red Upon power-up, the OK indicator is steadily red for a few moments. This 
is normal behavior and is not a fault.
If the OK indicator is steadily red for more than a few moments or 
changes to steadily red while in use, then a nonrecoverable major fault 
has occurred and project memory has been cleared.
To recover from a major fault, cycle power to the packaged controller, 
re-download the project, and put the packaged controller in Run mode.
If the OK indicator remains steadily red, contact your Rockwell 
Automation representative or local
 distributor.
Steady green Packaged controller is OK.
Flashing green The packaged controller is storing or loading a project to or from 
nonvolatile memory.
