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 

difference�
• 

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 SPx and 

rPx� SPx = upper value, rPx = lower value�

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

4.3  Diagnostic function

Output 2 is used as diagnostic output based on the DESINA specification if [OU2] 

= [dESI]�
•  If there is no fault, the output is switched and carries UB+ (if P-n = PnP) or UB- 

(if P-n = nPn)�

• 

In case of malfunctions the output becomes inactive. The following 

malfunctions are detected:

 -measuring cell defective;

 -short circuit in output 1
