Link to PV Stable Band
Figure 4.72
When the mode to link to the PV stable band is selected per Table 4.Z, the PV
display color will change according to whether the present value (PV) is lower
than, within, or higher than the PV stable band shown in Figure 4.73. The
width of the PV stable band is configured with the SP as the center, as shown
below.
Figure 4.73
The default band width is 5.0 (
°C/°F) for controllers with
Thermocouple/Resistance Thermometer Multi-Inputs and 5.0% FS for
Controllers with Analog Inputs.
