80 Ratio PID Controller
7.3 Ratio Controller Parameter Selections
Figure 7-4 illustrates how a Ratio Controller would appear with only the default values and power applied,
but no analog input or output signals. In Figure 7-4, ANO0 (TB1-10) is jumpered to ANI0 (TB1-2) to simu-
late process operation. The unit has the AC power supply and power cord 173D109U03. Connecting
ANO0 to ANI0 is done only for illustration purposes and is not necessary to configure the controller. If the
controller is connected to a Datalink network, then assign the Instrument Address (B001) and Baud Rate
(B002) first so the remaining datapoints may be entered at the SUPERVISOR-PC unit.
After this section, refer to Section 9 to configure the parameter display datapoints. The parameter display
is accessed by pressing the F2 push button from this display. Also, refer to Section 10.0, Instrument Tun-
ing, or Section 11.0, EASY-TUNE, to set the operating performance parameters: Proportional Band
(C106), Reset Time (C107), and Rate Time (C108). All other datapoints not shown in the illustration are at
the default value.
