Pulse time.
For a pulse-pause 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
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
Both frequencies must be set to 00, otherwise the controller will act as an impulse-frequency controller.
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.
5) Pulse + pause time
Define a period of time during which the relay is proportionally to the control deviation ON (pulse) or OFF
(pause), respectively.
6) Least pulse time
Set a minimum pulse time that the relay has to at least remain open to allow the actuator to react.
