A-96.250.111 / 211019 75
Control upwards or downwards.
Setpoint: User defined precess value for the selected parameter.
P-Band: Range below (upwards control) or above (downwards con-
trol) the set-point, within which the dosing intensity is reduced from
100% to 0% to reach the set-point without overshooting.
5.2.1.43 Control Parameters: if Parameter = DIS.
5.2.1.43.10 Setopint:
Range: 0.00 –10.00 ppm
5.2.1.43.20 P-Band:
Range: 0.00 –10.00 ppm
5.2.1.43 Control Parameters: if Parameter = pH/Redox
5.2.1.43.11 Setopint:
Range: -3.00 to + 15.00 pH
5.2.1.43.21 P-Band:
Range: 0.00 –2.00 pH
5.2.1.43 Control Parameters: if Parameter = Temperature
5.2.1.43.12 Setopint:
Range: -30 to + 120 °C
5.2.1.43.22 P-Band:
Range: 0.00 –100 °C
5.2.1.43 Control Parameters: if Parameter = Sample flow
5.2.1.43.13 Setopint:
Range: 0–600 rpm
5.2.1.43.23 P-Band:
Range: 0–600 rpm
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
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
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
stopped for safety reasons.
Range: 0–720 min
