Series 642
In the adaptive pressure controller mode, the RAMP TIME parameter also can be a value to minimize
over- / undershooting. The ramp could be used to harmonize the adaptive control algorithm.
GAIN FACTOR
The GAIN FACOTR is a control parameter to adapt the performance of the pressure control algorithm. A
higher gain results in faster response, higher over- / undershoot of pressure. A lower gain results in
slower response, lower over- / undershoot of pressure.
Example:
Set SENSOR DELAY of the adaptive pressure controller to the value 0.75
