10  Operation

After power on of the supply voltage the unit is in the Run mode (= normal operati-

on)� It carries out its measurement and evaluation functions and generates output 

signals according to the set parameters�
Operating indicators → 7 Operating and display elements.

10.1  Read the set parameter values

 

► Press [Mode/Enter] briefly to scroll the parameters�

 

► Press [Set] briefly to indicate the corresponding parameter value for 15 s� After 

another 15 s the unit returns to the Run mode�

10.2  Fault indication

[OL]

overload pressure (measuring range exceeded)

[UL]

underpressure range (measuring range below the minimum value)

[SC1]

short circuit in OUT1*

[SC2]

short circuit in OUT2*

[SC]

short circuit in both switching outputs*

*The output concerned is switched off as long as the short circuit exists�

This faults are indicated even if the display is deactivated�
