.. _safety_flags: Safety Flags ============ The safety flags are represented in software by the following enums .. doxygenenum:: safety_flag The safety flags can be temporarily or permanent. Some temporary flags are reset automatically, once the error condition disappears. Others have to be explicitly cleared. ---------------------------------------------------------------------------------------------------------------------------------- .. _safety_flags_adc_overflow: ERR_FLAG_MEAS_ADC_OVERFLOW -------------------------- ``ERR_FLAG_MEAS_ADC_OVERFLOW`` is triggered in case of an overflow in the signal path of the measurement ADC. This should never happen unless there is a bug in the software. ========== ============= ============= =========== persistent self-clearing Stops PID Panic Mode ========== ============= ============= =========== yes no yes no ========== ============= ============= =========== ---------------------------------------------------------------------------------------------------------------------------------- .. _safety_flags_adc_off: ERR_FLAG_MEAS_ADC_OFF --------------------- ``ERR_FLAG_MEAS_ADC_OFF`` signals that the measurement ADC for the PT1000 sensor is deactivated. This flag is automatically cleared by the firmware once the ADC is started. ========== ============= ============= =========== persistent self-clearing Stops PID Panic Mode ========== ============= ============= =========== no yes yes no ========== ============= ============= =========== ---------------------------------------------------------------------------------------------------------------------------------- .. _safety_flags_adc_watchdog: ERR_FLAG_MEAS_ADC_WATCHDOG -------------------------- ``ERR_FLAG_MEAS_ADC_WATCHDOG`` is used as a wire break detection mechanism. This flag is set when the PT1000 measurement ADC detects an invalid resistance measurement. .. seealso:: :ref:`ADC Watchdog` ========== ============= ============= =========== persistent self-clearing Stops PID Panic Mode ========== ============= ============= =========== no no yes no ========== ============= ============= =========== ---------------------------------------------------------------------------------------------------------------------------------- .. _safety_flags_adc_unstable: ERR_FLAG_MEAS_ADC_UNSTABLE -------------------------- ``ERR_FLAG_MEAS_ADC_UNSTABLE`` is set after startup of the PT1000 measuremnt or after reconfiguring the filter settings. .. seealso:: :ref:`firmware_meas_adc_filter` ========== ============= ============= =========== persistent self-clearing Stops PID Panic Mode ========== ============= ============= =========== no yes no no ========== ============= ============= =========== .. _safety_flags_safety_mem_corrupt: ERR_FLAG_SAFETY_MEM_CORRUPT --------------------------- ``ERR_FLAG_SAFETY_MEM_CORRUPT`` is set during the initialization of the controller, in case a corrupted safety memory is encountered. In this case the error memory is reinitialized and the flag is set in the error memory. Afer a reboot it will stay asserted until the safety backup memory is cleared .. seealso:: :ref:`backup_ram` ========== ============= ============= =========== persistent self-clearing Stops PID Panic Mode ========== ============= ============= =========== yes no yes no ========== ============= ============= ===========
