Hysteresis
Contr. settings 0,01 mS
For an ON/OFF controller you have to set the following parameters:
1) Set points S1 and S2
Set point S1 refers to relay 1, set point S2 refers to relay 2.
2) P range and integral action time for S1 and S2
For an ON/OFF controller set P range = 0 and integral time = 0.
3) Acting direction for S1 and S2
Select “raise“ if the dosage raises the measured value.
Select “lower“ if the dosage lowers the measured value.
4) Optionally a hysteresis
The hysteresis prevents fast switching in the vicinity of the set point. If hysteresis is activated (by setting a
value > 0) the relay switches only when the set point is exceeded by half the hysteresis.
