Function 4
Processing of the measured signals 4.1
The unit shows the current system pressure on its display� •
It generates 1 output signal according to the parameter setting� •
OUT1 switching signal for pressure limit values
Switching function 4.2
OUT1 changes its switching state if it is above or below the set switching limits
(SP1, rP1)� The following switching functions can be selected:
Hysteresis function / normally open: [OU1] = [Hno] (→ fig. 1). •
Hysteresis function / normally closed: [OU1] = [Hnc] (→ fig. 1). •
First the set point (SP1) is set, then the reset point (rP1) at the requested distance�
Window function / normally open: [OU1] = [Fno] (→ fig. 2). •
Window function / normally closed: [OU1] = [Fnc] (→ fig. 2). •
The width of the window can be set by means of the distance between SP1 and
rP1� SP1 = maximum value, rP1 = minimum value�
