  • Page 29: Operation

    Proline t-mass 500 HART Operation NOTICE Unlocking the device deactivates diagnostic functions, and the device may not be able to carry out its safety function in the unlocked SIL mode. ‣ Therefore, independent measures must be taken to ensure that there is no risk of danger while the SIL device is unlocked.

  • Page 30: Safe States

    Operation Proline t-mass 500 HART Safe states The system adopts one of the three states depending on the error detected: • Application error Application errors are detected by the device and a fixed failure current is output. The device can continue communicating via HART (device state: "temporarily safe"). This state persists until the application error is resolved and the device can again supply a valid measured value at the current output.
