The detection of open-circuit faults, 6 such as those caused by broken thermocouple wires. 7 Reading returns either '1' or '0'. 8 '1' = An open circuit such as broken thermocouple wires 9 has been detected. 10 '0' = No open circuit or broken thermocouple wires are detected 11 12What: /sys/bus/iio/devices/iio:deviceX/fault_ovuv 13KernelVersion: 5.1 14Contact: linux-iio@vger.kernel.org 15Description: 16 Overvoltage or Undervoltage Input Fault. The internal circuitry 17 is protected from excessive voltages applied to the thermocouple 18 cables by integrated MOSFETs at the T+ and T- inputs, and the 19 BIAS output. These MOSFETs turn off when the input voltage is 20 negative or greater than VDD. 21 Reading returns either '1' or '0'. 22 '1' = The input voltage is negative or greater than VDD. 23 '0' = The input voltage is positive and less than VDD (normal 24 state). 25
