AMI Oxytrace QED
Program List and Explanations
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 = Oxygen
5.2.1.43.10
Setopint:
Range: 0.00 ppb –20.00 ppm
5.2.1.43.20
P-Band:
Range: 0.00 ppb –20.00 ppm
5.2.1.43
Control Parameters
: if Parameter = Temperature
5.2.1.43.11
Setopint:
Range: -30 to + 130 °C
5.2.1.43.21
P-Band:
Range: 0 to + 100 °C
5.2.1.43
Control Parameters
: if Parameter = Sample flow
5.2.1.43.12
Setopint:
Range: 0–50 l/h
5.2.1.43.22
P-Band:
Range: 0–50 l/h
5.2.1.43
Control Parameters
: if Parameter = Saturation
5.2.1.43.13
Setopint:
Range: 0–200%
5.2.1.43.23
P-Band:
Range: 0–200%
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
