Parameterization and operation
P FACT NH4
Note: These settings are only necessary if NH
4
-N measurement in
effluent for feed back control is available!
Proportional factor for the PID closed loop controller for the NH4-N
concentration effluent aeration.
[1/mg/L]
INTEGRAL TIME NH4
Note: These settings are only necessary if NH
4
-N measurement in
effluent for feed back control is available!
Integral time for the PID closed loop controller for the NH4-N
concentration in the thickened sludge.
Note: INTEGRAL TIME NH4 is set to “0” to deactivate the integral
part of the PID controller.
[min]
DERIVATIVE TIME NH4
Note: These settings are only necessary if NH
4
-N measurement in
effluent for feed back control is available!
Derivation time for the PID closed loop controller for the NH4-N
concentration effluent aeration
Note: DERIVATIVE TIME NH4 is set to “0” to deactivate the
derivative part of the PID controller.
[min]
LIMITS
MIN DO
If a calculated DO set point is lower than the MIN DO value, the DO
set point is set to that value
[mg/L]
MAX DO
If a calculated DO set point is higher than the MIN DO value, the DO
set point is set to that value
[mg/L]
SMOOTHING
Smoothing on the calculated DO set point
[min]
INPUTS
MIN INFLOW
Minimum flow rate of influent according to measurement signal
corresponding to 0/4mA
[L/s]
MAX INFLOW
Maximum flow rate of influent according to measurement signal
corresponding to 20mA
[L/s]
0/4 to 20 mA
Transfer range of 0/4 to 20 mA current loop as set in connected flow
measuring instrument.
