9.3  User settings (optional)
9.3.1  Set delay for the switching outputs

• [dS1] = time delay for SP1 / FH1� If the system pressure exceeds SP1 or 

if the system pressure enters the acceptable range (window), the output 

changes the switching status when the time dS1 has elapsed�

• [dr1] = time delay for rP1 / FL1� If the system pressure falls below rP1 or 

if the system pressure leaves the acceptable range (window), the output 

changes the switching status when the time dr1 has elapsed�

 

Select [dS1] or [dr1] and set the value between 0 and 5000 ms in steps 

of 2 ms (at 0 the time delay is not active)�

9.3.2  Set damping for the switching outputs

 

Select [dAP] and set the value�

dAP value = response time between pressure change and change of the 

switching status in milliseconds�

The following fixed values can be set; they define the switching frequency (f 

in Hz) of the output:

9.3.3  Configuration of the display

 

Select [diS] and set the update rate and orientation of the display:

 -[d1]: update of the measured values every 50 ms�

 -[d2]: update of the measured values every 200 ms�

 -[d3]: update of the measured values every 600 ms�

 -[Ph]: display of the pressure peaks remains for a short time (peak 

hold)�

 -[rd1], [rd2], [rd3], [rPh]: display as for d1, d2, d3; rotated by 180°�

 -[OFF]: the display is switched off in the operating mode�

 

Select [cLor] and define the colour of the digital display:

 -[r-on]: display = red if output 1 is switched; display = green if output 1 

is not switched�

 -[G-on]: display = green if output 1 is switched; display = red if output 1 

is not switched�

 -[red]: the colour of the display is red / does not change�

 -[Gren]: the colour of the display is green / does not change�
