Clear faults

Clear major and minor faults remotely from the software. Also clear major faults using the controller keyswitch.
To clear faults
  1. On the
    Online
     toolbar, select the
    Controller Properties
     icon.
  2. In the
    Controller Properties
     dialog box, select the
    Major Faults
     tab.
  3. Select
    Clear Majors
     to clear the controller major faults and safety faults from the major fault log.
  4. If the controller keyswitch is in Run mode, the controller immediately begins running again when the fault is cleared. Confirm to the clear the faults.
    TIP:
    This clears the major faults and the major fault log. The results shows in the
    Recent Faults
     area of the dialog box.
    • A non-recoverable Safety fault exists, or
    • The project is Safety Locked, or
    • A Safety signature exists, or
    • The Safety Status (on the
      Safety
       tab of the controller properties ) is any value except OK,
      the Safety application and certain parts of the standard application cannot be edited online or offline. Once the Safety fault is cleared, available options are download, upload, or go online with the controller.
      When a recoverable Safety fault exists, editing is available in both standard and Safety applications.
      To clear a major fault from the controller keyswitch:
In the Safety controller, non-recoverable faults can occur. When a non-recoverable fault occurs in a Safety application on
GuardLogix
 5380 and
GuardLogix
 5580 controllers, the Safety task will not run again until you re-download the project. However, this rule is not applicable to the non-recoverable Safety Task Fault - Safety Task Watchdog Timeout (type 14, code 1), Safety Partner Missing (type 14, code 3), Safety Partner Unavailable (type 14, code 4).
When a non-recoverable fault occurs in a Safety application on
GuardLogix
 5370 and
GuardLogix
 5570 controllers, the Safety task will not run again until you re-download the project, or until the Safety components are reinitialized from a Safety signature in the controller.
When a non-recoverable Safety fault exists, editing in the standard application is still available. However, editing is restricted to only those portions of the Safety application that are accessible while in the Safety Locked state.
Whenever:
  1. Move the keyswitch from the RUN or REM position to the PROG position.
  2. Move the keyswitch from the PROG to the REM position.
  3. To restart the program, move the keyswitch from the REM to the RUN position.
    The OK LED on the controller should change from blinking red to solid green, and the RUN LED on the controller should be solid green.
  4. To not restart the program, move the keyswitch from the REM to the PROG position.
    The OK LED on the controller should change from blinking red to solid green, and the RUN LED on the controller should not be illuminated.
    TIP:
    This clears the major faults but not the major fault log (shown on the
    Major Faults
     tab).
To clear a minor fault from the software:
  1. On the
    Online
     toolbar, select the
    Controller Properties
     icon.
  2. In the
    Controller Properties
     dialog box, select the
    Major Faults
     tab.
  3. Select
    Clear Minors
     to clear the controller minor faults from the minor fault log.
