(5) Refer to Section 3.2.3 for details of the input signal error detection function.
POINT
(1) Set the input signal error detection upper limit value to less than 25mA.
If the setting is 25mA or more, the error may not be detected.
(2) For the Q62AD-DGH, set the input signal error detection lower limit value to
0mA or more.
If it has been set to less than 0mA, the error may not be detected.
(3) The following table shows the lower limit value, offset value, and gain value for
each range.
