Parameterization and operation
Q RETURN RATIO
Note: 0/4 to20 mA input can be used either for Qreci or for Qras.
If the value Q RETURN RATIO is “0” the RAS flow is calculated
bases on the mA input signal.
If the value is different from “0” the RAS flow is calculated from the
inflow:
Q RETURN = Q RETURN RATIO * INFLOW
within the limits of MIN RETURN SLUDGE and MAX RETURN
SLUDGE.
