4.5 FCO105 - Ratio Set Control w/ Operator Setpoint Limits
Factory Configured Option FCO105 provides a ratio set controller in Loop01. The setpoint to the Captive Flow
controller can be maintained as a ratio of the Captive Flow to Wild Flow. The controller has complete setpoint
tracking as well as ratio tracking. The local setpoint will track the Captive Flow signal when the loop is not in auto
(NA) OR is in External (Ratio) Set (ES). The value of the RATIO will be computed as Captive Flow
setpoint
/ Wild
Flow while in the tracking mode which occurs whenever the loop is not in auto (NA) OR is in Internal Set (IS). The
tracking features can be removed by setting the TC inputs to UNCONFIG. The Wild Flow signal will be displayed
on Variable X and the actual Ratio CF/WF will be displayed on Variable Y.
