5.2.1.40 Control Parameters: if Parameters = pH
5.2.1.40.18 Setpoint
Range: 0.00–14 pH
5.2.1.40.28 P-Band:
Range: 0.00–14 pH
5.2.1.40 Control Parameters: if Parameters = Ammonia
5.2.1.40.19 Setpoint
Range: 0.00–500 ppm
5.2.1.40.29 P-Band:
Range: 0.00–500 ppm
5.2.1.40.3 Reset time: The reset time is the time till the step response of a sin-
gle I-controller will reach the same value as it will be suddenly
reached by a P-controller.
Range: 0–9’000 sec
5.2.1.40.4 Derivative time: The derivative time is the time till the ramp re-
sponse of a single P-controller will reach the same value as it will
be suddenly reached by a D-controller.
Range: 0–9’000 sec
5.2.1.40.5 Control timeout: If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value
does not come closer to the setpoint, the dosing process will be
