4.2 Communication, parameter setting, evaluation

OUT1 (pin 4)

• Switching signal for system pressure limit

• Communication via IO-Link

OUT2 (pin 2) • Switching signal for system pressure limit

4.3 Switching function

OUTx changes its switching status 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)�

The hysteresis defined remains even if SPx is changed again�

• Window function / normally open: [OUx] = [Fno] (→ fig. 2).

• Window function / normally closed: [OUx] = [Fnc] (→ fig. 2).

The width of the window can be set by means of the difference between FHx and FLx� FHx = upper value, FLx = lower value�

1 2

P = system pressure; HY = hysteresis; FE = window

When set to the window function the set and reset points have a fixed hysteresis of 0�25 % of the measuring span�

4.4 IO-Link
