Program List and Explanations
Control upwards or downwards
Setpoint: User-defined process value for the selected parameter.
P-Band: Range below (upwards control) or above (downwards con-
trol) the set-point, within the dosing intensity is reduced from 100%
to 0% to reach the setpoint without overshooting.
5.2.1.43 Control Parameters: if Parameters = Conductivity
5.2.1.43.10 Setpoint
Range: 0 S–300 mS
5.2.1.43.20 P-Band:
Range: 0 S–300 mS
5.2.1.43 Control Parameters: if Parameters = Temperature
5.2.1.43.11 Setpoint
Range: -25 to +270 °C
5.2.1.43.21 P-Band:
Range: 0 to +100 °C
5.2.1.43 Control Parameters: if Parameters = Sample flow
5.2.1.43.12 Setpoint
Range: 0 –50 l/h
5.2.1.43.22 P-Band:
Range: 0 –50 l/h
5.2.1.43 Control Parameters: if Parameters = Cond. uc.
5.2.1.43.13 Setpoint
Range: 0 S–300 mS
5.2.1.43.23 P-Band:
Range: 0 S–300 mS
5.2.1.43.3 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
5.2.1.43.4 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
5.2.1.43.5 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
stopped for safety reasons.
Range: 0–720 min
