Switching to the High or Low Value when Input Disconnection
Occurs during Process Value Scaling with Negative Gain
If an input becomes disconnected during process value scaling with negative gain, either the maximum (high)
or minimum (low) process value can be set.
If the process value’s High/low value after sensor error setting is set to high, the maximum process value will be
set when the input is disconnected.
If the process value’s High/low value after sensor error setting is set to low, the minimum process value will be
set when the input is disconnected.

Process value scaling with negative gain
When process value is greater than 3,000,
output turns ON.
When input signal is less than 8 mA, output turns ON.
