3. P3-H
- hysteresis level of activation/deactivation of PK1 and PK2 outputs
4. MODE
- output operating mode:
Mode 0
– Absolute with two thresholds. Activation of PK1 and PK2 outputs is realized after
reaching of P1 and P2 values, respectively.
Mode 1
– Reverse with two thresholds. Operation is similar to the above mode. Deactivation
of PK1 and PK2 outputs is realized after reaching of P1 and P2 values, respectively.
