What: /sys/bus/iio/devices/iio:deviceX/fault_oc KernelVersion: 5.1 Contact: linux-iio@vger.kernel.org Description: Open-circuit fault. The detection of open-circuit faults, such as those caused by broken thermocouple wires. Reading returns either '1' or '0'. === ======================================================= '1' An open circuit such as broken thermocouple wires has been detected. '0' No open circuit or broken thermocouple wires are detected === ======================================================= What: /sys/bus/iio/devices/iio:deviceX/fault_ovuv KernelVersion: 5.1 Contact: linux-iio@vger.kernel.org Description: Overvoltage or Undervoltage Input Fault. The internal circuitry is protected from excessive voltages applied to the thermocouple cables by integrated MOSFETs at the T+ and T- inputs, and the BIAS output. These MOSFETs turn off when the input voltage is negative or greater than VDD. Reading returns either '1' or '0'. === ======================================================= '1' The input voltage is negative or greater than VDD. '0' The input voltage is positive and less than VDD (normal state). === =======================================================
