The controller output is calculated in this operating mode as
follows:
Yout = Wq x DF x (X-measured value x X-factor) x Yout-factor
Wq
Control variable 1 flow in %
DF
Set dosing factor in %
X-measured value
Control variable 2 measured value sensor
measuring module 1 in %
X factor
Amplification factor for X measured value
Yout
Determined controller output value %
Yout factor
This factor offers the option to increase the dosing
output if the setpoint is not reached with a dosing
factor DF of 100 %.
Setting range: 1.0– 4.0
Factory setting: 1.0

Single Feed Back Control
This operating mode controls the desired measured variable
according to the the provided setpoint.
A typical application example is chlorine control for tanks that are
circulated in cycles.
Please note
This control operating mode is also available for sensor measuring
module 2 if application 3 is selected, however, only with internal
setpoint input.
Note:
If this factor is increased, there is a danger that
the setpoint value will also not be reached with a
higher flow rate value, because the Yout value
takes the value 100 % prematurely.
