Setpoint: User defined precess value for the selected parameter.
P-Band: Range below (upwards control) or above (downwards
control) the set-point, within which the dosing intensity is reduced
from 100% to 0% to reach the set-point without overshooting.
Control Parameters: if Parameter = Hydrogen
Setopint:
Range: 0.00 ppb –20.00 ppm
P-Band:
Range: 0.00 ppb –20.00 ppm
Control Parameters: if Parameter = Temperature
Setopint:
Range: -30 to +130 °C
P-Band:
Range: 0 to +100 °C
Control Parameters: if Parameter = Sample flow
Setopint:
Range: 0–50 l/h
P-Band:
Range: 0–50 l/h
Control Parameters: if Parameter = Saturation
Setopint:
Range: 0–200%
P-Band:
Range: 0–200%
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 s
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 s
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
