Page 68: Applications
Functions Applications The configuration of the system is determined by: • Version of the SFC • The required measurement and control parameters • The installed components • the selection of the suitable application • the type of sensor module installed The SFC provides the option to customize the system to the various on-site systems using three integrated applications.
Page 69 Functions 4.5.1 Application 1 - Process measurement With application 1, the SFC operates exclusively as a measuring device. A maximum of four freely configurable alarm relays are available. The type of measurement is determined by the type of the sensor measuring module. Controller outputs are not supported in this application.

Page 71 Functions 4.5.2.1 Single feed forward with process measurement This operating mode controls the quantity-proportional dosing of disinfectants. The single feed forward with process measurement is only supported with sensor measuring modules with the Process Control option. A typical application is simple flow-controlled potable water chlorination, as shown in the following figure.
Page 72 Functions Please note If the measuring range end value of the flow meter is not identical with the actual maximum flow rate, a factor for adjusting the flow rate signal should be input in the menu „Inputs/Outputs“ - „Flow Wq“. For example: Measuring range flow meter = 5000 l/h / max.
Page 73 Functions 4.5.2.2 Single feedback closed loop control with process measurement This operating mode controls the desired measured variable according to the the provided setpoint. Single feedback closed loop control is supported with all sensor measuring modules (with and without the Process Control option). The following figure shows a typical application of a chlorine single feedback closed loop control for tanks which are circulated in cycles.

Page 75 Functions 4.5.2.3 Compound loop with process measurement The compound loop is a combination of the single feed forward with additional single feedback closed-loop control to correct control deviations. The compound loop is only supported with sensor measuring modules with the Process Control option. The following figure shows a typical chlorine compound loop as implemented in the treatment of potable water.
Page 76 Functions The compound loop outputs a dosing capacity proportional to the How the combi- flow rate, which does not have a fixed dosing factor proportional to control works the flow rate as in the single feed forward, but varies depending on demand.
Page 77 Functions Operation after a flow rate change: Behavior in operation The single feedback closed-loop control remains switched off (Ypi stop function) during the disturbance variables (flow rate change, positioner running time, dead time from line lengths). This maintains a stable control, which means the control operates with the dosing factor from the dosing factor table applicable for the new flow rate.
