5.7 Switching functions

Hysteresis function (configurable via teach function or IO-Link)
If the system pressure fluctuates around the set point, the hysteresis keeps the
switching status of the outputs stable. With increasing system pressure, the
output switches when reaching the switch point (SP).
Normally open contact (HNO): Active
■
Contact normally closed (HNC): Inactive
■
With system pressure falling again, the output will not switch back before the reset
point (RP) is reached.
Normally open contact (HNO): Inactive
