For an impulse-frequency controller you have to set the following parameters:
1) Set points S1 and S2
S1 refers to relay 1, S2 refers to relay 2.
2) P range and integral action time for S1 and S2
Adjust a P range > 0. For a P controller set integral time = 0, for a PI controller set an integral time > 0.
3) Pulse-frequencies for S1 and S2
Enter the maximum pulse-frequency that corresponds to 100% dosage.
4) The acting direction for S1 and S2
Select „raise“ if the dosage raises the measured value.
Select „lower“ if the dosage lowers the measured value.
