Sensor Selection
You need to configure a controller to match the input device, which is normally a
thermocouple or RTD. When you select an input device the controller
automatically sets the input linearization to match the sensor. It also sets high
and low limits, which in turn limit the range high and range low values.
Use Sensor Type and Input Type (Input Group) to select the appropriate sensor.
Figure 4.6 — Sensor Ranges
Range Low and Range High
The controller constrains the set point to a value between range high and range
low. Range high cannot be set higher than the sensor high limit or lower than
range low. Range low cannot be set lower than the sensor low limit or higher
than range high.
Use Set Point (Operation Group), Range High and Range Low (Input Group) to
select or view values for the corresponding parameters.
