AMI Codes-II
Program List and Explanations
A-96.250.571 / 050517 85
Control upwards/downwards
Setpoint: User-defined process value (Measured value or flow)
P-Band: Range below (upwards control) or above (downwards
control) the set-point, within the dosing intensity is reduced from
100% to 0% to reach the set-point without overshooting.
5.2.1.43 Control Parameters: if Parameters = DIS
5.2.1.43.10 Setpoint: 0–5 ppm or 0–5 mg/l
5.2.1.43.20 P-Band: 0–5 ppm 0–5 mg/l
5.2.1.43 Control Parameters: if Parameters = pH
5.2.1.43.11 Setpoint: 0 –14 pH
5.2.1.43.21 P-Band: 0 –14 pH
5.2.1.43 Control Parameters: if Parameters = Temperature
5.2.1.43.12 Setpoint: -30 to +120 °C
5.2.1.43.22 P-Band: 0 to +100 °C
5.2.1.43 Control Parameters: if Parameters = Sample Flow
5.2.1.43.13 Setpoint: 0–600 B/s
5.2.1.43.23 P-Band: 0 –200 B/s
Reset time: The reset time is the time till the step response of a
single 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
response 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
