• The most common causes are wiring mistakes or an incompatible sensor is being used.
    • Ensure that the analog sensor being used provides a 0-10 VDC output signal and not of another variety such as 0-5 VDC or 4-20mA.
    • Use a digital multi-meter to ensure that the sensor is outputting DC voltage in the range of 0-10 VDC.
    • Ensure that the 0-10 VDC signal wire from the analog sensor is wired to pin #1 on the analog input of the Caddis device.
    • Make sure that the ground wire from the analog sensor is wired to pin #4 on the analog input of the Caddis device.
    • Ensure that the Caddis device is grounded properly as a floating ground will cause many problems, including problems with the analog input port.
    • If an oscilloscope is available, ensure that there is not excessive electrical noise on the 0-10 VDC analog sensor output wire.
    • Check with LCM2M support to ensure that the scaling values are set up correctly for your sensor. Please be prepared to share the datasheet for the sensor with LCM2M support.
