  • Page 28: Error Response

    CSCP 012 C-DIAS SAFETY CPU Error Response In the event of an error, please consult the chapter "LED Displays", as important infor- mation on the runtime status of the system can be derived from the status and error dis- play. Since errors in general are of a complex nature, do not perform a diagnosis based on the LEDs alone (consult the corresponding chapter in the Safety System Handbook as well).

  • Page 29: Configuration Distribution Error

    C-DIAS SAFETY CPU CSCP 012 During restart, the Safety CPU first runs the POST (Power On Self Test). In the POST, whether the Safety CPU is configured or not is determined. If the Flash memory in the Safety CPU is empty, it changes to the service mode and switches the status LED (ST) to continuously on.

  • Page 30: Troubleshooting

    CSCP 012 C-DIAS SAFETY CPU Troubleshooting • Check all modules in the system for completeness and type conformity • Check that all modules are error-free • Check all connector cables • Cancel the error with the QUIT_ERROR command If the Safety CPU remains in the error status after the QUIT_ERROR command has been executed, it must be retested using the SafetyDesigner.
