AMI Hydrazine
Program List and Explanations
If Control upwards or Control downwards is active
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:

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
