Clear a Major Fault
If the OK status indicator flashes red because of a recoverable major
fault, clear the fault by following these steps.
1. Turn the controller keyswitch from PROG to RUN and back to
PROG.
2. Go online with RSLogix 5000 software.
3. On the Controller Properties dialog box, click the Major Faults
tab to find information about the fault.
If the OK status indicator is flashing red because of a nonrecoverable
major fault, the controller:
• initially displayed a solid red OK indicator.
• reset itself.
• cleared the project from its memory.
• set the OK indicator to flashing red.
• produced a major recoverable fault and generated a
corresponding fault code in the RSLogix 5000 project.
– Fault code 60 means the CompactFlash card is not installed.
– Fault code 61 means the CompactFlash card is installed.
Follow these steps to recover from fault code 60 or 61.
1. Turn the controller keyswitch from PROG to RUN and back to
PROG.
2. Go online with RSLogix 5000 and download the project.
3. Change to REM RUN or RUN mode.
If the issue persists, record the status of the OK and RS-232 indicators
before cycling power and contacting Rockwell Automation support.
