(6) Example of input signal error detection
To detect an error when the analog input value becomes lower than 2.4mA for a channel with an input range
of 4mA to 20mA:
Substitute the following values into the input signal error detection lower limit value.
• Input signal error detection lower limit value: 2.4mA
• Input range lower limit value (Offset value): 4.0mA
• Gain value: 20.0mA
Therefore, set the input signal error detection setting value to 100 (10.0%).
In this case, the input signal error detection value behaves as follows. (With the 100 (10%) setting, an error is
detected when the value is not only 2.4mA, but also 21.6mA.)
