The following modes are available for the analog input 3. In modes 2 & 3 a current loop loss trip is generated if the input current falls below 3mA.
In modes 2 and 4 the destination parameter is at a value equivalent to 0.0% when the input current is less than 4mA. In modes 3 and 5 the destination
parameter is at a value equivalent to 100.0% when the input current is less than 4mA.
