4.3.4 POINT DISPLAY 3 (CDM = 3, RATIO CONTROLLER)
The Ratio Controller Display is illustrated in Figure 4-6. In the illustration the control module tag
name appears at the top of the display. The left side of the Ratio Controller Display (CDM = 3)
contains a fifty segment vertical axis with numerical values above and below it indicating its upper
and lower ranges. Left of the vertical axis is the process variable bar. Alarm limits appear left of the
process variable bar as indicators at the alarm limit values. On the immediate right of the vertical
axis are the setpoint arrowhead and ratio tick-pointer. The ratio tick-pointer indicates the value the
setpoint will assume when ratio operation is selected. Beneath the vertical axis is a forty segment
horizontal axis with the C and O close and open valve indicators at either end. The output bar moves
under the horizontal axis and the output value is also indicated numerically below the output bar. On
the right side of the display is the RAtio legend and the RAtio value that affects the output appears
immediately beneath it. The middle legend is the engineering units and the lower legend is PV with
the Process Variable value appearing below it. If the process variable bar moves beyond either
alarm limit indicator, an alarm overlay appears in the area below the control module tag name.
