- 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).
