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�
FH

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�
