4.2 Switching function OUTx changes its switching state if it is above or below the set switching limits (SPx, rPx) The following switching functions can be selected: • Hysteresis function / normally open: [OUx] = [Hno] (→ fig. 1). • Hysteresis function / normally closed: [OUx] = [Hnc] (→ fig. 1). First the set point (SPx) is set, then the reset point (rPx) with the requested differ- ence •... -
